Energy Conservation Program: Energy Conservation Standards for
Consumer Conventional Cooking Products
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Supplemental notice of proposed rulemaking and announcement of
public meeting.
-----------------------------------------------------------------------
SUMMARY: The Energy Policy and Conservation Act, as amended (``EPCA''),
prescribes energy conservation standards for various consumer products
and certain commercial and industrial equipment, including consumer
conventional cooking products. EPCA also requires the U.S. Department
of Energy (``DOE'') to periodically determine whether more-stringent
standards would be technologically feasible and economically justified,
and would result in significant energy savings. In this supplemental
notice of proposed rulemaking (``SNOPR''), DOE proposes new and amended
energy conservation standards for consumer conventional cooking
products, and also announces a public meeting to receive comment on
these proposed standards and associated analyses and results.
DATES:
Meeting: DOE will hold a public meeting via webinar on Tuesday,
January 31, 2023, from 1:00 p.m. to 4:00 p.m. See section VII of this
document, ``Public Participation,'' for webinar registration
information, participant instructions, and information about the
capabilities available to webinar participants.
Comments: DOE will accept comments, data, and information regarding
this SNOPR no later than April 3, 2023.
Comments regarding the likely competitive impact of the proposed
standard should be sent to the Department of Justice contact listed in

I. Synopsis of the Proposed Rule
The Energy Policy and Conservation Act, Public Law 94-163, as
amended (``EPCA''),\1\ authorizes DOE to regulate the energy efficiency
of a number of consumer products and certain industrial equipment. (42
U.S.C. 6291-6317). Title III, Part B of EPCA \2\ established the Energy
Conservation Program for Consumer Products Other Than Automobiles. (42
U.S.C. 6291-6309). These products include consumer conventional cooking
products, the subject of this rulemaking.
---------------------------------------------------------------------------
\1\ All references to EPCA in this document refer to the statute
as amended through the Energy Act of 2020, Public Law 116-260 (Dec.
27, 2020), which reflect the last statutory amendments that impact
Parts A and A-1 of EPCA.
\2\ For editorial reasons, upon codification in the U.S. Code,
Part B was redesignated Part A.
---------------------------------------------------------------------------
Pursuant to EPCA, any new or amended energy conservation standard
must be designed to achieve the maximum improvement in energy
efficiency that DOE determines is technologically feasible and
economically justified. (42 U.S.C. 6295(o)(2)(A)). Furthermore, the new
or amended standard must result in a significant conservation of
energy. (42 U.S.C. 6295(o)(3)(B)). EPCA also provides that not later
than six years after issuance of any final rule establishing or
amending a standard, DOE must publish either a notice of determination
that standards for the product do not need to be amended, or a notice
of proposed rulemaking including new proposed energy conservation
standards (proceeding to a final rule, as appropriate). (42 U.S.C.
6295(m)).
In accordance with these and other statutory provisions discussed
in this document, DOE proposes new and amended energy conservation
standards for consumer conventional cooking products. Per its authority
in 42 U.S.C. 6295(h)(2), DOE proposes to remove the existing
prescriptive standard for gas cooking tops prohibiting a constant
burning pilot light. Instead, for conventional cooking tops, DOE
proposes performance standards only, shown in Table I.1 which are the
maximum allowable integrated annual energy consumption (``IAEC'') and
expressed in kilowatt-hours per year (``kWh/year'') for electric
cooking tops and thousand British thermal units per year (``kBtu/
year'') for gas cooking tops. The IAEC includes active mode, standby
mode, and off mode energy use. These proposed standards for
conventional cooking tops, if adopted, would apply to all product
classes listed in Table I.1 and manufactured in, or imported into, the
United States starting on the date three years after the publication of
any final rule for this rulemaking. DOE notes that constant burning
pilot lights, which are currently prohibited under the existing
prescriptive standard for gas cooking tops, 10 CFR 430.32(j), consume
approximately 2,000 kBtu/year. While DOE's proposal would remove this
prescriptive requirement from its regulations, DOE notes that, based on
its review of the existing prescriptive standard prohibiting constant
burning pilots for gas cooking tops, the proposed
[[Page 6820]]
performance standards of 1,204 kBtu per year for gas cooking tops would
not be achievable by products if they were to incorporate a constant
burning pilot.
Table I.1--Proposed Energy Conservation Performance Standards for
Conventional Cooking Tops
------------------------------------------------------------------------
Maximum integrated annual
Product class energy consumption (IAEC)
------------------------------------------------------------------------
Electric Open (Coil) Element Cooking Tops.... 199 kWh/year.
Electric Smooth Element Cooking Tops......... 207 kWh/year.
Gas Cooking Tops............................. 1,204 kBtu/year.
------------------------------------------------------------------------
For conventional ovens, the proposed standard is a prescriptive
design requirement for the control system of the oven. Conventional
ovens shall not be equipped with a control system that uses a linear
power supply. (See Table I.2). These proposed standards, if adopted,
would apply to all conventional ovens manufactured in, or imported
into, the United States starting on the date three years after the
publication of the final rule for this rulemaking. DOE also notes that
the current prescriptive standards for conventional gas ovens
prohibiting constant burning pilot lights would continue to be
applicable. (10 CFR 430.32(j)). Table I.2 provides a summary of the
proposed standards for conventional ovens.

------------------------------------------------------------------------
* A linear power supply produces unregulated as well as regulated power.
The unregulated portion of a linear power supply typically consists of
a transformer that steps alternating current (``AC'') line voltage
down, a voltage rectifier circuit for AC to direct current (``DC'')
conversion, and a capacitor to produce unregulated, direct current
output. Linear power supplies are described in section IV.C.1.b of
this SNOPR.
A. Benefits and Costs to Consumers
Table I.3 presents DOE's evaluation of the economic impacts of the
proposed standards, represented by trial standard level (``TSL'') 2, on
consumers of conventional cooking products, as measured by the average
life-cycle cost (``LCC'') savings and the simple payback period
(``PBP'').\3\ The shipment-weighted average LCC savings are positive
for all product classes, and the shipment-weighted PBP is less than the
average lifetime of consumer conventional cooking products, which is
estimated to be 16.8 years for electric cooking products and 14.5 years
for gas cooking products (see section IV.F.6 of this document).
---------------------------------------------------------------------------
\3\ The average LCC savings refer to consumers that are affected
by a standard and are measured relative to the efficiency
distribution in the no-new-standards case, which depicts the market
in the compliance year in the absence of new or amended standards
(see section IV.F.9 of this document). The simple PBP, which is
designed to compare specific efficiency levels, is measured relative
to the baseline product (see section IV.C of this document).

[[Page 6821]]
DOE's analysis of the impacts of the proposed standards on
consumers is described in section IV.F of this document.
B. Impact on Manufacturers
The industry net present value (``INPV'') is the sum of the
discounted cash flows to the industry from the base year through the
end of the analysis period (2022-2056). Using a real discount rate of
9.1 percent, DOE estimates that the INPV for manufacturers of consumer
conventional cooking products in the case without new and amended
standards is $1,607 million in 2021 dollars. Under the proposed
standards, the change in INPV is estimated to range from -9.6 percent
to -9.4 percent, which is approximately -$154.8 million to -$150.4
million. In order to bring products into compliance with new and
amended standards, it is estimated that the industry would incur total
conversion costs of $183.4 million.
DOE's analysis of the impacts of the proposed standards on
manufacturers is described in section IV.J of this document. The
analytic results of the manufacturer impact analysis (``MIA'') are
presented in section V.B.2 of this document.
C. National Benefits and Costs 4
---------------------------------------------------------------------------
\4\ All monetary values in this document are expressed in 2021
dollars.
---------------------------------------------------------------------------
DOE's analyses indicate that the proposed energy conservation
standards for consumer conventional cooking products would save a
significant amount of energy. Relative to the case without new and
amended standards, the lifetime energy savings for consumer
conventional cooking products purchased in the 30-year period that
begins in the anticipated year of compliance with the new and amended
standards (2027-2056) amount to 0.46 quadrillion British thermal units
(``Btu''), or quads.\5\ This represents a savings of 3.4 percent
relative to the energy use of these products in the case without
amended standards (referred to as the ``no-new-standards case'').
---------------------------------------------------------------------------
\5\ The quantity refers to full-fuel-cycle (``FFC'') energy
savings. FFC energy savings includes the energy consumed in
extracting, processing, and transporting primary fuels (i.e., coal,
natural gas, petroleum fuels), and, thus, presents a more complete
picture of the impacts of energy efficiency standards. For more
information on the FFC metric, see section IV.H.1 of this document.
---------------------------------------------------------------------------
The cumulative net present value (``NPV'') of total consumer
benefits of the proposed standards for consumer conventional cooking
products ranges from $0.65 billion (at a 7-percent discount rate) to
$1.71 billion (at a 3-percent discount rate). This NPV expresses the
estimated total value of future operating-cost savings minus the
estimated increased product and installation costs for consumer
conventional cooking products purchased in 2027-2056.
In addition, the proposed standards for consumer conventional
cooking products are projected to yield significant environmental
benefits. DOE estimates that the proposed standards would result in
cumulative emission reductions (over the same period as for energy
savings) of 21.9 million metric tons (``Mt'') \6\ of carbon dioxide
(``CO2''), 2.2 thousand tons of sulfur dioxide
(``SO2''), 51.8 thousand tons of nitrogen oxides
(``NOX''), 244.9 thousand tons of methane
(``CH4''), 0.1 thousand tons of nitrous oxide
(``N2O''), and 0.01 tons of mercury (``Hg'').\7\
---------------------------------------------------------------------------
\6\ A metric ton is equivalent to 1.1 short tons. Results for
emissions other than CO2 are presented in short tons.
\7\ DOE calculated emissions reductions relative to the no-new-
standards case, which reflects key assumptions in the Annual Energy
Outlook 2022 (``AEO2022''). AEO2022 represents current federal and
state legislation and final implementation of regulations as of the
time of its preparation. See section IV.K of this document for
further discussion of AEO2022 assumptions that effect air pollutant
emissions.
---------------------------------------------------------------------------
DOE estimates the value of climate benefits from a reduction in
greenhouse gases (``GHG'') using four different estimates of the social
cost of CO2 (``SC-CO2''), the social cost of
methane (``SC-CH4''), and the social cost of nitrous oxide
(``SC-N2O''). Together these represent the social cost of
GHG (``SC-GHG'').\8\ DOE used interim SC-GHG values developed by an
Interagency Working Group on the Social Cost of Greenhouse Gases
(``IWG'').\9\ The derivation of these values is discussed in section
IV.L of this document. For presentational purposes, the climate
benefits associated with the average SC-GHG at a 3-percent discount
rate are estimated to be $1.17 billion. DOE does not have a single
central SC-GHG point estimate and it emphasizes the importance and
value of considering the benefits calculated using all four SC-GHG
estimates.
---------------------------------------------------------------------------
\8\ On March 16, 2022, the Fifth Circuit Court of Appeals (No.
22-30087) granted the federal government's emergency motion for stay
pending appeal of the February 11, 2022, preliminary injunction
issued in Louisiana v. Biden, No. 21-cv-1074-JDC-KK (W.D. La.). As a
result of the Fifth Circuit's order, the preliminary injunction is
no longer in effect, pending resolution of the federal government's
appeal of that injunction or a further court order. Among other
things, the preliminary injunction enjoined the defendants in the
case from ``adopting, employing, treating as binding, or relying
upon'' the interim estimates of the social cost of greenhouse
gases--which were issued by the Interagency Working Group on the
Social Cost of Greenhouse Gases on February 26, 2021--to monetize
the benefits of reducing greenhouse gas emissions. As reflected in
this rule, DOE has reverted to its approach prior to the injunction
and presents monetized benefits where appropriate and permissible
under law.

Gases, Technical Support Document: Social Cost of Carbon, Methane,
and Nitrous Oxide. Interim Estimates Under Executive Order 13990,
Washington, DC, February 2021. www.whitehouse.gov/wp-content/uploads/2021/02/TechnicalSupportDocument_SocialCostofCarbonMethaneNitrousOxide.pdf.
---------------------------------------------------------------------------
DOE estimated the monetary health benefits from SO2 and
NOX emissions reductions using benefit per ton estimates
from the scientific literature, as discussed in section IV.L of this
document. DOE estimated the present value of the health benefits would
be $0.61 billion using a 7-percent discount rate, and $1.63 billion
using a 3-percent discount rate.\10\ DOE is currently only monetizing
(for SO2 and NOX) PM2.5 precursor
health benefits and (for NOX) ozone precursor health
benefits, but will continue to assess the ability to monetize other
effects such as health benefits from reductions in direct
PM2.5 emissions.
---------------------------------------------------------------------------
\10\ DOE estimates the economic value of these emissions
reductions resulting from the considered TSLs for the purpose of
complying with the requirements of Executive Order 12866.
---------------------------------------------------------------------------
Table I.4 summarizes the economic benefits and costs expected to
result from the proposed standards for consumer conventional cooking
products. There are other important unquantified effects, including
certain unquantified climate benefits, unquantified public health
benefits from the reduction of toxic air pollutants, direct
PM2.5 and other emissions that affect both indoor and
outdoor air quality, unquantified energy security benefits, and
distributional effects, among others.

Note: This table presents the costs and benefits associated with
consumer conventional cooking products shipped in 2027--2056. These
results include benefits to consumers which accrue after 2056 from the
products shipped in 2027--2056.
* Climate benefits are calculated using four different estimates of the
social cost of carbon (SC-CO2), methane (SC-CH4), and nitrous oxide
(SC-N2O) (model average at 2.5 percent, 3 percent, and 5 percent
discount rates; 95th percentile at 3 percent discount rate) (see
section IV.L of this document). Together these represent the global SC-
GHG. For presentational purposes of this table, the climate benefits
associated with the average SC-GHG at a 3 percent discount rate are
shown, but DOE does not have a single central SC-GHG point estimate.
On March 16, 2022, the Fifth Circuit Court of Appeals (No. 22-30087)
granted the Federal government's emergency motion for stay pending
appeal of the February 11, 2022, preliminary injunction issued in
Louisiana v. Biden, No. 21-cv-1074-JDC-KK (W.D. La.). As a result of
the Fifth Circuit's order, the preliminary injunction is no longer in
effect, pending resolution of the Federal government's appeal of that
injunction or a further court order. Among other things, the
preliminary injunction enjoined the defendants in that case from
``adopting, employing, treating as binding, or relying upon'' the
interim estimates of the social cost of greenhouse gases--which were
issued by the Interagency Working Group on the Social Cost of
Greenhouse Gases on February 26, 2021--to monetize the benefits of
reducing greenhouse gas emissions. As reflected in this rule, DOE has
reverted to its approach prior to the injunction and presents
monetized benefits where appropriate and permissible under law.
** Health benefits are calculated using benefit-per-ton values for NOX
and SO2. DOE is currently only monetizing (for SO2 and NOX) PM2.5
precursor health benefits and (for NOX) ozone precursor health
benefits, but will continue to assess the ability to monetize other
effects such as health benefits from reductions in direct PM2.5
emissions. See section IV.L of this document for more details.
[dagger] Total and net benefits include those consumer, climate, and
health benefits that can be quantified and monetized. For presentation
purposes, total and net benefits for both the 3-percent and 7-percent
cases are presented using the average SC-GHG with 3-percent discount
rate, but DOE does not have a single central SC-GHG point estimate.
DOE emphasizes the importance and value of considering the benefits
calculated using all four SC-GHG estimates.
[Dagger] Costs include incremental equipment costs as well as
installation costs.
The benefits and costs of the proposed standards can also be
expressed in terms of annualized values. The monetary values for the
total annualized net benefits are (1) the reduced consumer operating
costs, minus (2) the increase in product purchase prices and
installation costs, plus (3) the value of climate and health benefits
of emission reductions, all annualized.\11\
---------------------------------------------------------------------------
\11\ To convert the time-series of costs and benefits into
annualized values, DOE calculated a present value in 2022, the year
used for discounting the NPV of total consumer costs and savings.
For the benefits, DOE calculated a present value associated with
each year's shipments in the year in which the shipments occur
(e.g., 2030), and then discounted the present value from each year
to 2022. Using the present value, DOE then calculated the fixed
annual payment over a 30-year period, starting in the compliance
year, that yields the same present value.
---------------------------------------------------------------------------
The national operating savings are domestic private U.S. consumer
monetary savings that occur as a result of purchasing the covered
products and are measured for the lifetime of consumer conventional
cooking products shipped in 2027-2056. The benefits associated with
reduced emissions achieved as a result of the proposed standards are
also calculated based on the lifetime of consumer conventional cooking
products shipped in 2027-2056. Total benefits for both the 3-percent
and 7-percent cases are presented using the average GHG social costs
with 3-percent discount rate. Estimates of SC-GHG are presented for all
four discount rates in section IV.L of this document.
Table I.5 presents the total estimated monetized benefits and costs
associated with the proposed standard, expressed in terms of annualized
values. The results under the primary estimate are as follows.
Using a 7-percent discount rate for consumer benefits and costs and
health benefits from reduced NOX and SO2
emissions, and the 3-percent discount rate case for climate benefits
from reduced GHG emissions, the estimated cost of the standards
proposed in this rule is $32.5 million per year in increased equipment
costs, while the estimated annual benefits are $100.8 million in
reduced equipment operating costs, $67.0 million in climate benefits,
and $64.9 million in health benefits. In this case, the net benefit
would amount to $200.3 million per year.
Using a 3-percent discount rate for all benefits and costs, the
estimated cost of the proposed standards is $32.2 million per year in
increased equipment costs, while the estimated annual benefits are
$130.7 million in reduced operating costs, $67.0 million in climate
benefits, and $93.8 million in health benefits. In this case, the net
benefit would amount to $259.2 million per year.

Note: This table presents the costs and benefits associated with consumer conventional cooking products shipped
in 2027-2056. These results include benefits to consumers which accrue after 2056 from the products shipped in
2027-2056. The Primary, Low Net Benefits, and High Net Benefits Estimates utilize projections of energy prices
from the AEO2022 Reference case, Low Economic Growth case, and High Economic Growth case, respectively. In
addition, incremental equipment costs reflect a medium decline rate in the Primary Estimate, a low decline
rate in the Low Net Benefits Estimate, and a high decline rate in the High Net Benefits Estimate. The methods
used to derive projected price trends are explained in sections IV.F.1 and IV.H.3 of this document. Note that
the Benefits and Costs may not sum to the Net Benefits due to rounding.
* Climate benefits are calculated using four different estimates of the global SC-GHG (see section IV.L of this
document). For presentational purposes of this table, the climate benefits associated with the average SC-GHG
at a 3 percent discount rate are shown, but the Department does not have a single central SC-GHG point
estimate, and it emphasizes the importance and value of considering the benefits calculated using all four SC-
GHG estimates. On March 16, 2022, the Fifth Circuit Court of Appeals (No. 22-30087) granted the Federal
government's emergency motion for stay pending appeal of the February 11, 2022, preliminary injunction issued
in Louisiana v. Biden, No. 21-cv-1074-JDC-KK (W.D. La.). As a result of the Fifth Circuit's order, the
preliminary injunction is no longer in effect, pending resolution of the Federal government's appeal of that
injunction or a further court order. Among other things, the preliminary injunction enjoined the defendants in
that case from ``adopting, employing, treating as binding, or relying upon'' the interim estimates of the
social cost of greenhouse gases--which were issued by the Interagency Working Group on the Social Cost of
Greenhouse Gases on February 26, 2021--to monetize the benefits of reducing greenhouse gas emissions. Aa
reflected in this rule, DOE has reverted to its approach prior to the injunction and presents monetized
benefits where appropriate and permissible under law.
** Health benefits are calculated using benefit-per-ton values for NOX and SO2. DOE is currently only monetizing
(for SO2 and NOX) PM2.5 and (for NOX) ozone precursor health benefits, but will continue to assess the ability
to monetize other effects such as health benefits from reductions in direct PM2.5 emissions. See section IV.L
of this document for more details.
[dagger] Total benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with 3-
percent discount rate, but the Department does not have a single central SC-GHG point estimate.
[Dagger] Costs include incremental equipment costs as well as installation costs.
DOE's analysis of the national impacts of the proposed standards is
described in sections IV.H, IV.K and IV.L of this document.
D. Conclusion
DOE has tentatively concluded that the proposed standards represent
the maximum improvement in energy efficiency that is technologically
feasible and economically justified, and would result in the
significant conservation of energy. Specifically, with regards to
technological feasibility, products achieving these standard levels are
already commercially available for all product classes covered by this
proposal. As for economic justification, DOE's analysis shows that the
benefits of the proposed standard exceed, to a great extent, the
burdens of the proposed standards. That conclusion remains true under
any reasonable analytical assumption--i.e., the proposed standards are
net beneficial under any discount rate (both for climate and non-
climate benefits and costs), any cost scenario, and any other scenario
DOE analyzed. Moreover, because consumer operating cost savings and
health benefits alone greatly exceed costs under all such assumptions
and scenarios, DOE noted that this conclusion does not depend on
climate benefits (though DOE's estimates of climate benefits remain
important and robust).
Using a 7-percent discount rate for consumer benefits and costs and
NOX and SO2 reduction benefits, and a 3-percent
discount rate case for GHG social costs, the estimated cost of the
proposed standards for consumer conventional cooking products is $32.5
million per year in increased product costs, while the estimated annual
benefits are $100.8 million in reduced product operating costs, $67.0
million in climate benefits and $64.9 million in health benefits. The
net monetized benefit amounts to $200.3 million per year.
The significance of energy savings offered by a new or amended
energy conservation standard cannot be determined without knowledge of
the specific circumstances surrounding a given rulemaking.\12\ For
example, some covered products and equipment have substantial energy
consumption occur during periods of peak energy demand. The impacts of
these products on the energy infrastructure can be more pronounced than
products with
[[Page 6824]]
relatively constant demand. Accordingly, DOE evaluates the significance
of energy savings on a case-by-case basis.

in New or Revised Energy Conservation Standards and Test Procedures
for Consumer Products and Commercial/Industrial Equipment, 86 FR
70892, 70901 (Dec. 13, 2021).
---------------------------------------------------------------------------
As previously mentioned, the standards are projected to result in
estimated national energy savings of 0.46 quads FFC, the equivalent of
the electricity use of 19 million residential homes in one year. The
NPV of consumer benefit for these projected energy savings is $0.65
billion using a discount rate of 7 percent, and $1.71 billion using a
discount rate of 3 percent. The cumulative emissions reductions
associated with these energy savings are 21.9 Mt of CO2, 2.2
thousand tons of SO2, 51.8 thousand tons of NOX,
0.01 tons of Hg, 244.9 thousand tons of CH4, and 0.1
thousand tons of N2O. The estimated monetary value of the
climate benefits from reduced GHG emissions (associated with the
average SC-GHG at a 3-percent discount rate) is $1.17 billion. The
estimated monetary value of the health benefits from reduced
SO2 and NOX emissions is $0.61 billion using a 7-
percent discount rate and $1.63 billion using a 3-percent discount
rate. As such, DOE has initially determined the energy savings from the
proposed standard levels are ``significant'' within the meaning of 42
U.S.C. 6295(o)(3)(B). A more detailed discussion of the basis for these
tentative conclusions is contained in the remainder of this document
and the accompanying technical support document (``TSD'').\13\
---------------------------------------------------------------------------
\13\ The TSD is available in the docket for this rulemaking at
www.regulations.gov/docket/EERE-2014-BT-STD-0005/document.
---------------------------------------------------------------------------
DOE also considered more-stringent energy efficiency levels as
potential standards, and is still considering them in this rulemaking.
However, DOE has tentatively concluded that the potential burdens of
the more-stringent energy efficiency levels would outweigh the
projected benefits.
Based on consideration of the public comments DOE receives in
response to this document and related information collected and
analyzed during the course of this rulemaking effort, DOE may adopt
energy efficiency levels presented in this document that are either
higher or lower than the proposed standards, or some combination of
level(s) that incorporate the proposed standards in part.
II. Introduction
The following section briefly discusses the statutory authority
underlying this proposed rule, as well as some of the relevant
historical background related to the establishment of standards for
consumer conventional cooking products.
A. Authority
EPCA authorizes DOE to regulate the energy efficiency of a number
of consumer products and certain industrial equipment. Title III, Part
B of EPCA established the Energy Conservation Program for Consumer
Products Other Than Automobiles. These products include consumer
conventional cooking products, the subject of this document. (42 U.S.C.
6292(a)(10)). EPCA prescribed energy conservation standards for these
products (42 U.S.C. 6295(h)(1)), and directs DOE to conduct future
rulemakings to determine whether to amend these standards. (42 U.S.C.
6295(h)(2)). EPCA further provides that, not later than six years after
the issuance of any final rule establishing or amending a standard, DOE
must publish either a notice of determination that standards for the
product do not need to be amended, or a notice of proposed rulemaking
(``NOPR'') including new proposed energy conservation standards
(proceeding to a final rule, as appropriate). (42 U.S.C. 6295(m)(1)).
The energy conservation program under EPCA consists essentially of
four parts: (1) testing, (2) labeling, (3) the establishment of Federal
energy conservation standards, and (4) certification and enforcement
procedures. Relevant provisions of EPCA specifically include
definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293),
labeling provisions (42 U.S.C. 6294), energy conservation standards (42
U.S.C. 6295), and the authority to require information and reports from
manufacturers (42 U.S.C. 6296).
Federal energy efficiency requirements for covered products
established under EPCA generally supersede State laws and regulations
concerning energy conservation testing, labeling, and standards. (42
U.S.C. 6297(a)-(c)). DOE may, however, grant waivers of Federal
preemption for particular State laws or regulations, in accordance with
the procedures and other provisions set forth under EPCA. (See 42
U.S.C. 6297(d)).
Subject to certain criteria and conditions, DOE is required to
develop test procedures to measure the energy efficiency, energy use,
or estimated annual operating cost of each covered product. (42 U.S.C.
6295(r)). Manufacturers of covered products must use the prescribed DOE
test procedure as the basis for certifying to DOE that their products
comply with the applicable energy conservation standards adopted under
EPCA and when making representations to the public regarding the energy
use or efficiency of those products. (42 U.S.C. 6293(c) & 42 U.S.C.
6295(s)) Similarly, DOE must use these test procedures to determine
whether the products comply with standards adopted pursuant to EPCA.
(42 U.S.C. 6295(s)) The DOE test procedures for conventional cooking
tops appear at title 10 of the Code of Federal Regulations (``CFR'')
part 430, subpart B, appendix I1 (``appendix I1''). There are currently
no DOE test procedures for conventional ovens.
DOE must follow specific statutory criteria for prescribing new or
amended standards for covered products, including consumer conventional
cooking products. Any new or amended standard for a covered product
must be designed to achieve the maximum improvement in energy
efficiency that the Secretary of Energy (``Secretary'') determines is
technologically feasible and economically justified. (42 U.S.C.
6295(o)(2)(A) & 42 U.S.C. 6295(o)(3)(B)) Furthermore, DOE may not adopt
any standard that would not result in the significant conservation of
energy. (42 U.S.C. 6295(o)(3))
Moreover, DOE may not prescribe a standard if DOE determines by
rule that the standard is not technologically feasible or economically
justified. (42 U.S.C. 6295(o)(3)(B)). In deciding whether a proposed
standard is economically justified, DOE must determine whether the
benefits of the standard exceed its burdens. (42 U.S.C.
6295(o)(2)(B)(i)). DOE must make this determination after receiving
comments on the proposed standard, and by considering, to the greatest
extent practicable, the following seven statutory factors:
(1) The economic impact of the standard on the manufacturers and on
the consumers of the products subject to such standard;
(2) The savings in operating costs throughout the estimated average
life of the covered products in the type (or class) compared to any
increase in the price of, or in the initial charges for, or maintenance
expenses of, the covered products which are likely to result from the
imposition of the standard;
(3) The total projected amount of energy (or as applicable, water)
savings likely to result directly from the imposition of the standard;
(4) Any lessening of the utility or the performance of the covered
products likely to result from the imposition of the standard;
(5) The impact of any lessening of competition, as determined in
writing by the Attorney General, that is likely to
[[Page 6825]]
result from the imposition of the standard;
(6) The need for national energy and water conservation; and
(7) Other factors the Secretary considers relevant.
(42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII)).
Further, EPCA establishes a rebuttable presumption that a standard
is economically justified if the Secretary finds that the additional
cost to the consumer of purchasing a product complying with an energy
conservation standard level will be less than three times the value of
the energy savings during the first year that the consumer will receive
as a result of the standard, as calculated under the applicable test
procedure. (42 U.S.C. 6295(o)(2)(B)(iii)).
EPCA also contains what is known as an ``anti-backsliding''
provision, which prevents the Secretary from prescribing any amended
standard that either increases the maximum allowable energy use or
decreases the minimum required energy efficiency of a covered product.
(42 U.S.C. 6295(o)(1)). Also, the Secretary may not prescribe an
amended or new standard if interested persons have established by a
preponderance of the evidence that the standard is likely to result in
the unavailability in the United States in any covered product type (or
class) of performance characteristics (including reliability),
features, sizes, capacities, and volumes that are substantially the
same as those generally available in the United States. (42 U.S.C.
6295(o)(4)).
Additionally, EPCA specifies requirements when promulgating an
energy conservation standard for a covered product that has two or more
subcategories. DOE must specify a different standard level for a type
or class of product that has the same function or intended use, if DOE
determines that products within such group: (A) consume a different
kind of energy from that consumed by other covered products within such
type (or class); or (B) have a capacity or other performance-related
feature which other products within such type (or class) do not have
and such feature justifies a higher or lower standard. (42 U.S.C.
6295(q)(1)). In determining whether a performance-related feature
justifies a different standard for a group of products, DOE must
consider such factors as the utility to the consumer of the feature and
other factors DOE deems appropriate. Id. Any rule prescribing such a
standard must include an explanation of the basis on which such higher
or lower level was established. (42 U.S.C. 6295(q)(2)).
Finally, pursuant to the amendments contained in the Energy
Independence and Security Act of 2007 (``EISA 2007''), Public Law 110-
140, any final rule for new or amended energy conservation standards
promulgated after July 1, 2010, is required to address standby mode and
off mode energy use. (42 U.S.C. 6295(gg)(3)). Specifically, when DOE
adopts a standard for a covered product after that date, it must, if
justified by the criteria for adoption of standards under EPCA (42
U.S.C. 6295(o)), incorporate standby mode and off mode energy use into
a single standard, or, if that is not feasible, adopt a separate
standard for such energy use for that product. (42 U.S.C.
6295(gg)(3)(A)-(B)). DOE's current test procedures for conventional
cooking tops address standby mode and off mode energy use. In this
rulemaking, DOE intends to incorporate such energy use into any amended
energy conservation standards for conventional cooking tops that it may
adopt. As discussed in section III.C of this document, DOE does not
have a current test procedure for conventional ovens. As a result, a
performance standard that addresses standby mode and off mode energy
use is not feasible for conventional ovens. However, in this SNOPR, DOE
is proposing to adopt prescriptive design requirements for the control
system of conventional ovens that would address standby mode and off
mode energy use.
B. Background
1. Current Standards
In a final rule published on April 8, 2009 (``April 2009 Final
Rule''), DOE prescribed the current energy conservation standards for
consumer conventional cooking products that prohibits constant burning
pilots for all gas cooking products (i.e., gas cooking products both
with or without an electrical supply cord) manufactured on and after
April 9, 2012. 74 FR 16040. These standards are set forth in DOE's
regulations at 10 CFR 430.32(j)(1)-(2).
2. History of Standards Rulemaking for Consumer Conventional Cooking
Products
The National Appliance Energy Conservation Act of 1987 (``NAECA''),
Public Law 100-12, amended EPCA to establish prescriptive standards for
gas cooking products, requiring gas ranges and ovens with an electrical
supply cord that are manufactured on or after January 1, 1990, not to
be equipped with a constant burning pilot light. (42 U.S.C.
6295(h)(1)). NAECA also directed DOE to conduct two cycles of
rulemakings to determine if more stringent or additional standards were
justified for kitchen ranges and ovens. (42 U.S.C. 6295(h)(2)).
DOE undertook the first cycle of these rulemakings and published a
final rule on September 8, 1998, which found that no standards were
justified for conventional electric cooking products at that time. 63
FR 48038. In addition, partially due to the difficulty of conclusively
demonstrating at that time that elimination of standing pilots for
conventional gas cooking products without an electrical supply cord was
economically justified, DOE did not include amended standards for
conventional gas cooking products in the final rule. 63 FR 48038,
48039-48040. For the second cycle of rulemakings, DOE published the
April 2009 Final Rule amending the energy conservation standards for
consumer conventional cooking products to prohibit constant burning
pilots for all gas cooking products (i.e., gas cooking products both
with or without an electrical supply cord) manufactured on or after
April 9, 2012. DOE decided to not adopt energy conservation standards
pertaining to the cooking efficiency of conventional electric cooking
products because it determined that such standards would not be
technologically feasible and economically justified at that time. 74 FR
16040, 16085.\14\
---------------------------------------------------------------------------
\14\ As part of the April 2009 Final Rule, DOE decided not to
adopt energy conservation standards pertaining to the cooking
efficiency of microwave ovens. DOE has since published a final rule
on June 17, 2013, adopting energy conservation standards for
microwave oven standby mode and off mode. 78 FR 36316. DOE is not
considering energy conservation standards for microwave ovens as
part of this proposed rule. A separate rulemaking is underway
addressing energy conservation standards for microwave ovens. See
www.regulations.gov/docket/EERE-2017-BT-STD-0023/document.
---------------------------------------------------------------------------
As noted, EPCA requires that, not later than six years after the
issuance of a final rule establishing or amending a standard, DOE
publish a NOPR proposing new standards or a notification of
determination that the existing standards do not need to be amended.
(42 U.S.C. 6295(m)(1)). On February 12, 2014, DOE published a request
for information (``RFI'') document (``February 2014 RFI'') to initiate
the mandatory review process imposed by EPCA. 79 FR 8337. In making
this determination, DOE must evaluate whether new or amended standards
would (1) yield a significant savings in energy use and (2) be both
technologically feasible and economically justified. (42 U.S.C.
6295(m)(1)(B) and 42 U.S.C. 6295(o)(3)(B))
On June 10, 2015, DOE published a NOPR (``June 2015 NOPR'')
proposing
[[Page 6826]]
new and amended energy conservation standards for consumer conventional
ovens. 80 FR 33030. In the June 2015 NOPR, DOE noted that it was
deferring its decision regarding whether to adopt amended energy
conservation standards for conventional cooking tops, pending further
study. 80 FR 33030, 33038-33040.
On September 2, 2016, DOE published an SNOPR (``September 2016
SNOPR'') proposing new and amended energy conservation standards for
conventional cooking tops based on the amendments to the test procedure
as proposed in a test procedure SNOPR published on August 22, 2016
(``August 2016 TP SNOPR;'' 81 FR 57374). 81 FR 60784. In the September
2016 SNOPR, DOE also revised its proposal from the June 2015 NOPR for
conventional ovens from a performance-based standard to a prescriptive
standard given that DOE had proposed to repeal the test procedure for
conventional ovens in the August 2016 TP SNOPR. 81 FR 60784, 60793-
60794. (The history of the test procedures for conventional cooking
tops and conventional ovens is discussed in greater detail in section
III.C of this document.)
On December 14, 2020, DOE published a notification of proposed
determination (``NOPD'') proposing not to amend the energy conservation
standards for consumer conventional cooking products (``December 2020
NOPD''). 85 FR 80982. In the December 2020 NOPD, DOE initially
determined that amended energy conservation standards for consumer
conventional cooking products would not be economically justified and
would not result in a significant conservation of energy.
DOE held a public meeting on January 28, 2021, to solicit feedback
from stakeholders concerning the December 2020 NOPD, and received
comments in response to the December 2020 NOPD from the interested
parties listed in Table II.1.

energy conservation standards for consumer conventional cooking
products. (Docket NO. EERE-2014-BT-STD-0005, which is maintained at

(commenter name, comment docket ID number, page of that document).
---------------------------------------------------------------------------
3. Basis for This Proposed Rule
In the December 2020 NOPD, the tentative determination that amended
energy conservation standards for consumer conventional cooking
products would not be economically justified and would not result in a
significant conservation of energy hinged, in significant part, on
DOE's proposal to screen out all identified technology options that
would improve the performance of gas cooking tops to efficiencies above
the baseline efficiency level. 85 FR 80982, 81003-81004. DOE noted in
the December 2020 NOPD that the estimates for energy savings associated
with a specific technology option for gas cooking tops, optimized
burner and grate design, may vary depending on the test procedure, and
thus DOE screened out this technology options from further analysis of
gas cooking tops. Id. at 85 FR 81004. As discussed in section III.C of
this document, at the time of the December 2020 NOPD, DOE had withdrawn
its test procedure for conventional cooking tops. However, DOE
additionally stated in the December 2020 NOPD that it would reevaluate
the energy savings associated with this technology option if it
considered performance standards in a future rulemaking. Id.
On August 22, 2022, DOE published a final rule (``August 2022 TP
Final Rule'') establishing a test procedure for conventional cooking
tops, at 10 CFR part 430, subpart B, appendix I1, ``Uniform Test Method
for the Measuring the Energy Consumption of Conventional Cooking
Products.'' 87 FR 51492. As a result, in this SNOPR, DOE is
reevaluating the energy savings associated with the optimized burner
and grate design technology option for conventional gas cooking tops
and has tentatively found that amended energy conservation standards
for consumer conventional cooking products are economically justified
and would result in a significant conservation of energy.
As discussed in section III.C of this document, this SNOPR
specifically further differs from the September 2016 SNOPR in that the
performance standards evaluated for conventional cooking tops are based
on the new appendix I1 test procedure, rather than on the now-withdrawn
former appendix I.
C. Deviation From Appendix A
In accordance with section 3(a) of 10 CFR part 430, subpart C,
appendix A (``appendix A''), DOE notes that it is deviating from the
provision in appendix A regarding the NOPR stage for an energy
conservation standard rulemaking. Section 6(f)(2) of appendix A
specifies that the length of the public comment period for a NOPR will
vary depending upon the circumstances of the particular rulemaking, but
will not be less than 75 calendar days. For this SNOPR, DOE has opted
to instead
[[Page 6827]]
provide a 60-day comment period. DOE requested comment in the February
2014 RFI on the technical and economic analyses and provided
stakeholders a 60-day comment period, after publishing the comment
period extension. Additionally, DOE provided a 30-day comment period
for the September 2016 SNOPR with an extension to 60 days, and a 75-day
comment period for the December 2020 NOPD. 81 FR 60784, 81 FR 67219, 85
FR 80982. DOE has relied on many of the same analytical assumptions and
approaches as used in the September 2016 SNOPR and December 2020 NOPD.
As such, DOE believes a 60-day comment period is appropriate and will
provide interested parties with a meaningful opportunity to comment on
the proposed rule.
III. General Discussion
DOE developed this proposal after considering oral and written
comments, data, and information from interested parties that represent
a variety of interests. The following discussion addresses issues
raised by these commenters.
A. General Comments
This section summarizes general comments received from interested
parties regarding rulemaking timing and process.
GEA supported the comments submitted by AHAM and incorporated them
by reference. (GEA, No. 85 at p. 1).
AHAM stated that the 2017 statutory deadline to publish a final
rule regarding consumer conventional cooking product energy
conservation standards has passed, and that DOE should not hold this
rule open and should finalize a determination not to amend the
standard. (AHAM, No. 84 at p. 4). AHAM commented that it is
disingenuous of other commenters to simultaneously challenge DOE for
failing to timely meet an obligation while also urging it to further
delay meeting that same obligation. (Id.) AHAM added that, should DOE
believe energy conservation standards based on measured efficiency
could be justified once a reliable test procedure exists, DOE can
propose a rule at any time after the publication of the determination
not to amend the standard, although AHAM questioned whether such a
standard would be justified under EPCA. (Id.) AHAM further noted that
EPCA requires that DOE re-evaluate its determination not to amend the
standard within 3 years of the issuance of that determination. 42
U.S.C. 6295(m)(3)(B). (Id.)
GEA commented that DOE's actions on this standard are long past
due. (GEA, No. 85 at p. 2).
The CA IOUs urged DOE to consider the implications of the December
2020 NOPD on the Executive Order 13990 and the announcement that the
DOE would be re-examining the withdrawal of the cooking top test
procedure. (CA IOUs, No. 89 at p. 5)
In the most recent stage of this rulemaking, DOE published the
December 2020 NOPD in which it tentatively concluded that new and
amended energy conservation standards for consumer conventional cooking
products would not be economically justified and would not result in a
significant conservation of energy, in part because it was unable to
evaluate certain technology options for gas cooking tops in the absence
of a test procedure for these products. 85 FR 80982. The test procedure
established in the August 2022 TP Final Rule, discussed in more detail
in section III.C of this document, provides testing results upon which
these SNOPR analyses for conventional cooking tops were based. DOE
reevaluated its analyses as quickly as possible once the test procedure
was finalized. President Biden's Executive Order 13990, which addresses
the social cost of carbon and other greenhouse gases, are discussed in
section IV.L of this document.
The Joint Gas Associations agreed with the DOE's tentative
determination in the December 2020 NOPD that no new standards are
justified. (Joint Gas Associations, No. 86 at pp. 2-3). The Joint Gas
Associations further supported the December 2020 NOPD's tentative
determination that neither of the February 2020 Process Rule's
thresholds for significant energy savings are met for TSL 2 or TSL 1
for consumer conventional cooking products. (Id.)
The Joint Commenters expressed concern that DOE indicated it was in
the process of revising the Process Rule, yet the Department cited the
energy savings thresholds from the February 2020 Process Rule to
justify the proposed determination of no amended standards. (Joint
Commenters, No. 87 at p. 1). The Joint Commenters added that with
billions of consumer savings at risk, DOE should not move forward with
this determination until DOE completed the indicated revisions to the
Process Rule. (Id.) The Joint Commenters further commented that DOE
should eliminate the energy savings thresholds as part of the Process
Rule revision in order to ensure that critical energy and utility bill
savings are not lost. (Joint Commenters, No. 87 at p. 2).
In evaluating the significance of the estimated energy savings for
the December 2020 NOPD, DOE applied a two-part numeric threshold test
that was then applicable under section 6(b) of appendix A to 10 CFR
part 430 subpart C (Jan. 1, 2021 edition).\16\ Specifically, the
threshold required that an energy conservation standard result in a
0.30 quads reduction in site energy use over a 30-year analysis period
or a 10-percent reduction in site energy use over that same period. See
85 FR 8626, 8670 (Feb. 14, 2020). In the December 2020 NOPD, DOE stated
that the estimated site energy savings at the max-tech level evaluated
at that time was 0.57 quads, which exceeded the 0.3-quads threshold,
but expressed concern that this TSL might result in the unavailability
of certain product types for conventional ovens because there would be
significant uncertainty as to whether commercial-style manufacturers
would be able to test their products in the absence of a DOE test
procedure for conventional ovens. 85 FR 80982, 81053. (See section
III.C of this document for discussion of the repeal of the conventional
oven test procedure.) DOE then evaluated the next lower TSL than max-
tech and estimated that it would save an estimated 0.22 quads of site
energy over the evaluation period, which would represent a 4.9-percent
decrease in the site energy use of the evaluated products. Id. That
estimated site energy savings would not reach the 0.3 quad-threshold or
the 10-percent site energy saving threshold enumerated in section 6(b)
of appendix A to 10 CFR part 430 subpart C (Jan. 1, 2021 edition).
Accordingly, DOE tentatively determined in the December 2020 NOPD that
new or amended energy conservation standards for consumer conventional
cooking products would not result in significant conservation of energy
and be economically justified. Id.
---------------------------------------------------------------------------
\16\ DOE established the numeric threshold test in section 6(b)
of appendix A to 10 CFR part 430 subpart C in a final rule published
on February 14, 2020. 85 FR 8626.
---------------------------------------------------------------------------
On December 13, 2021, DOE published in the Federal Register, a
final rule that amended appendix A. 86 FR 70892 (``December 2021 Final
Rule''). The December 2021 Final Rule, in part, removed the numeric
threshold in section 6(b) of appendix A for determining when the
significant energy savings criterion is met, reverting to DOE's prior
practice of making such determinations on a case-by-case basis. 86 FR
70892.
Adkins commented that many consumer cooking products are already
[[Page 6828]]
operating at near peak capabilities and added that introducing stronger
regulations on consumer cooking products would increase the cost of
these products for consumers, lowering consumption with little to no
positive environmental impact. (Adkins, No. 81 at p. 1)
Ahmad commented that DOE's tentative determination of no economic
justification for cooking products may still be valid because of a lack
of significant technological advancements since the September 2016
SNOPR. (Ahmad, No. 82 at p. 1)
AHAM stated that no significant changes have occurred to justify
new standards since the April 2009 Final Rule that determined that
energy conservation standards for consumer conventional cooking
products were not justified. (AHAM, No. 84 at p. 4)
GEA stated that consumer conventional cooking products use little
energy compared to other DOE regulated products and therefore DOE's
limited resources are better served on products for whom greater energy
savings is feasible. (GEA, No. 85 at p. 2) GEA supported DOE's proposed
determination not to amend standards. (Id.)
The Joint Gas Associations agreed with DOE's tentative
determination in the December 2020 NOPD that a potential amended
standard based on TSL 3 would result in a negative net present value, a
negative INPV range, a potential unavailability of certain product
types for conventional ovens, and a loss of certain functions that
provide utility to customers, and that a potential standard at TSL 3 is
not economically justified. (Joint Gas Associations, No. 86 at p. 3)
The Joint Gas Associations further stated that any potential positive
impacts from an amended standard at TSL 3 are not outweighed by these
estimated negative impacts. (Id.)
The Joint Commenters commented that, without the February 2020
Process Rule thresholds, adopting standards at TSL 2 from the December
2020 NOPD could provide full-fuel cycle savings of 0.6 quads and
consumer savings of up to $3.7 billion. (Joint Commenters, No. 87 at p.
2) The Joint Commenters added that adopting standards at the TSL 2 from
the December 2020 NOPD would provide full-fuel-cycle energy savings of
0.28 quads and NPV savings of up to $2 billion for electric smooth
element cooking tops with an incremental cost of only $3, and would
achieve full-fuel-cycle energy savings of 0.1 quads and NPV savings of
up to $730 million for self-cleaning freestanding conventional electric
ovens with an incremental cost of $1. (Id. referencing 85 FR 80982,
81049-81050).
NEEA commented that according to the 2015 RECS, while cooking
represents a small amount of overall home energy use (1.4 percent in
residential electricity use and 2.9 percent in residential gas use),
when combined with the potential individual unit savings for cooking
tops shown in the December 2020 NOPD and external testing, performance-
based standards for cooking tops could lead to significant national
energy savings. (NEEA, No. 88 at p. 3) NEEA noted that DOE's testing
showed that conventional gas cooking tops with similar average burner
input rates can vary in annual energy use by as much as 27 percent, and
conventional oven efficiency for units with similar input rates varied
by 11 percent and 19 percent for gas and electric units, respectively.
(Id. referencing 85 FR 80982, 81008-81009) NEEA also noted that DOE
found potential energy savings on average of 24 percent for induction
electric cooking tops compared to a baseline smooth element electric
cooking top. NEEA commented that this is in line with recent testing
conducted by the Food Service Technology Center,\17\ which found a 23-
percent efficiency improvement. (Id. referencing 85 FR 80982, 81035)
NEEA recommended that DOE proceed with updated standards for cooking
tops and conventional ovens once the test procedure has been updated,
commenting that this would allow DOE to consider performance-based
standards for cooking tops and conventional ovens that harness energy
efficiency opportunities, which could not be fully achieved through the
prescriptive standards considered in the December 2020 NOPD (Id.).

---------------------------------------------------------------------------
The CA IOUs commented that, given the recent shift in consumer
behavior, there is a high likelihood that a reanalysis of the TSL 2
defined in the December 2020 NOPD based on more recent cooking
frequency data would lead to site savings greater than 0.3 quads,
exceeding the February 2020 Process Rule's significant energy savings
threshold. (CA IOUs, No. 89 at pp. 3-4)
EPCA requires that any new or amended energy conservation standards
prescribed by DOE for any type (or class) of covered product be
designed to achieve the maximum improvement in energy efficiency (or
for certain products, water efficiency) which the Secretary determines
is technologically feasible and economically justified. Upon the
finalization of a new test procedure for consumer conventional cooking
products, DOE reevaluated its analysis from the December 2020 NOPD,
including its tentative determination at that time to screen out the
technology option for improved burner and grate design. DOE is updating
its tentative conclusions in this SNOPR to reflect the use of optimized
burners and grates on gas cooking tops to achieve higher efficiencies.
See section IV.A.2 and section IV.B of this document, as well as
chapters 3 and 4 of the TSD for this SNOPR for additional information
on this technology option and screening analysis. DOE also updated its
information regarding the prevalence of baseline technologies in
conventional ovens on the market. See section IV.F.8 of this document
and chapter 7 of the TSD for this SNOPR. Pursuant to these updates and
others outlined in this SNOPR, DOE revised its analysis regarding the
technological feasibility and economic justification of new and amended
energy conservation standards for consumer conventional cooking
products and presents a summary of the results in section V of this
SNOPR.
B. Product Classes and Scope of Coverage
When evaluating and establishing energy conservation standards, DOE
divides covered products into product classes by the type of energy
used or by capacity or other performance-related features that justify
differing standards. In making a determination whether a performance-
related feature justifies a different standard, DOE must consider such
factors as the utility of the feature to the consumer and other factors
DOE determines are appropriate. (42 U.S.C. 6295(q))
As discussed in section II.A of this document, 42 U.S.C.
6292(a)(10) of EPCA covers kitchen ranges and ovens, or ``cooking
products.'' DOE's regulations define ``cooking products'' as consumer
products that are used as the major household cooking appliances. They
are designed to cook or heat different types of food by one or more of
the following sources of heat: Gas, electricity, or microwave energy.
Each product may consist of a horizontal cooking top containing one or
more surface units \18\ and/or one or more heating compartments. 10 CFR
430.2. DOE is not considering energy
[[Page 6829]]
conservation standards for microwave ovens as part of this proposed
rulemaking.\19\
---------------------------------------------------------------------------
\18\ The term surface unit refers to burners for gas cooking
tops and electric resistance heating elements or inductive heating
elements for electric cooking tops.
\19\ See www.regulations.gov/docket/EERE-2017-BT-STD-0023/document.
---------------------------------------------------------------------------
DOE defines a combined cooking product as a household cooking
appliance that combines a conventional cooking top and/or conventional
oven with other appliance functionality, which may or may not include
another cooking product (10 CFR part 430, subpart B, appendix I). In
this analysis, DOE is not treating combined cooking products as a
distinct product category and is not basing its product classes on such
a category. Instead, DOE is evaluating energy conservation standards
for conventional cooking tops and conventional ovens separately.
Because combined cooking products consist, in part, of a cooking top
and/or oven, the cooking top and oven standards would continue to apply
to the individual components of the combined cooking product.
As part of the 2009 standards rulemaking for consumer conventional
cooking products, DOE did not consider energy conservation standards
for consumer conventional gas cooking products with higher burner input
rates, including products marketed as ``commercial-style'' or
``professional-style,'' due to a lack of available data for determining
efficiency characteristics of those products. DOE considered such
products to be gas cooking tops with burner input rates greater than
14,000 British thermal units per hour (``Btu/h'') and gas ovens with
burner input rates greater than 22,500 Btu/h. 74 FR 16040, 16054 (Apr.
8, 2009); 72 FR 64432, 64444-64445 (Nov. 15, 2007). DOE also stated
that the DOE cooking products test procedures at that time may not
adequately measure performance of gas cooking tops and ovens with
higher burner input rates. 72 FR 64432, 64444-64445 (Nov. 15, 2007).
As part of the February 2014 RFI, DOE stated that it tentatively
planned to consider energy conservation standards for all consumer
conventional cooking products, including commercial-style gas cooking
products with higher burner input rates. In addition, DOE stated that
it may consider developing test procedures for these products and
determine whether separate product classes are warranted. 79 FR 8337,
8340 (Feb. 12, 2014).
As discussed in section III.C of this document, DOE's new test
procedure for conventional cooking tops in appendix I1 measures the
energy use of commercial-style gas cooking tops with high burner input
rates. DOE also repealed the conventional oven test procedure in a
final rule published on December 16, 2016 (``December 2016 TP Final
Rule''). 81 FR 91418.
In the December 2020 NOPD, in the absence of Federal test
procedures to measure the energy use or energy efficiency of
conventional cooking tops and conventional ovens, DOE evaluated
prescriptive design requirements for the control system of conventional
electric smooth element cooking tops and conventional ovens, including
commercial-style ovens with higher burner input rates. 85 FR 80982,
80988. In the December 2020 NOPD, DOE stated that it would maintain the
existing prescriptive design requirements for all conventional gas
cooking products, noting that the current definitions for
``conventional cooking top'' and ``conventional oven'' in 10 CFR 430.2
already cover commercial-style gas cooking products with higher burner
input rates, as these products are household cooking appliances with
surface units or compartments intended for the cooking or heating of
food by means of a gas flame. Id. In the December 2020 NOPD, DOE did
not propose a separate product class for gas cooking tops and ovens
with higher burner input rates that are marketed as ``commercial-
style'' and did not propose separate definitions for these products.
Id.
Adkins supported higher standards for industrial cooking equipment
and stated that the degree of energy saved by an individual consumer is
minimal when compared to that of an entire business or corporation.
(Adkins, No. 81 at p. 1)
Ahmad commented that microwave ovens should be the subject of
amended energy conservation standards due to widespread use in the U.S.
(Ahmad, No. 82 at p. 1)
The scope of this rulemaking is limited to cooking products. As
defined in 10 CFR 430.2, ``cooking products'' are consumer products
that are used as the major household cooking appliances. They are
designed to cook or heat different types of food by one or more of the
following sources of heat: Gas, electricity, or microwave energy. Each
product may consist of a horizontal cooking top containing one or more
surface units and/or one or more heating compartments. Industrial
cooking equipment and microwave ovens are not in the scope of this
proposed rule.
In this SNOPR, DOE is proposing to define a portable conventional
cooking top as a conventional cooking top designed to be moved from
place to place. Using this definition, DOE is proposing that the
proposed standards for conventional cooking tops would apply to
portable models according to their means of heating (gas, electric open
(coil) element, or electric smooth element).
DOE requests comment on its proposed definition for portable
conventional cooking top and DOE's proposal to include portable
conventional cooking tops in the existing product classes. DOE also
seeks data and information on its initial determination not to
differentiate conventional cooking tops on the basis of portability
when considering product classes for this SNOPR analysis.
C. Test Procedure
EPCA sets forth generally applicable criteria and procedures for
DOE's adoption and amendment of test procedures. (42 U.S.C. 6293)
Manufacturers of covered products must use these test procedures to
certify to DOE that their product complies with energy conservation
standards and to quantify the efficiency of their product. DOE's
current energy conservation standards for consumer conventional cooking
products are prescriptive standards that prohibits constant burning
pilots for all gas cooking products (i.e., gas cooking products both
with or without an electrical supply cord) manufactured on and after
April 9, 2012. 74 FR 16040. (See 10 CFR 430.32(j)(2).)
DOE established test procedures for consumer conventional cooking
products in a final rule published in the Federal Register on May 10,
1978. 43 FR 20108, 20120-20128. DOE revised its test procedures for
cooking products to more accurately measure their efficiency and energy
use, and published the revisions as a final rule in 1997. 62 FR 51976
(Oct. 3, 1997). These test procedure amendments included: (1) A
reduction in the annual useful cooking energy; (2) a reduction in the
number of self-clean oven cycles per year; and (3) incorporation of
portions of International Electrotechnical Commission (``IEC'')
Standard 705-1988, ``Methods for measuring the performance of microwave
ovens for household and similar purposes,'' and Amendment 2-1993 for
the testing of microwave ovens. Id. The test procedures for consumer
conventional cooking products established provisions for determining
estimated annual operating cost, cooking efficiency (defined as the
ratio of cooking energy output to cooking energy input), and energy
factor (defined as the ratio of annual useful cooking energy output to
total annual energy input). 10 CFR 430.23(i); appendix I. These
provisions
[[Page 6830]]
for consumer conventional cooking products were not used for compliance
with any energy conservation standards because the standards to date
have been design requirements; in addition, there is no EnergyGuide
\20\ labeling program for cooking products.
---------------------------------------------------------------------------
\20\ For more information on the EnergyGuide labeling program,
see: consumer.ftc.gov/articles/how-use-energyguide-label-shop-home-appliances.
---------------------------------------------------------------------------
DOE subsequently conducted a rulemaking to address standby and off
mode energy consumption, as well as certain active mode (i.e., fan-only
mode) testing provisions, for consumer conventional cooking products,
satisfying the EPCA requirement that DOE include measures of standby
mode and off mode power in its test procedures for residential
products, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)). DOE
published a final rule on October 31, 2012 (``October 2012 TP Final
Rule''), adopting standby and off mode provisions. 77 FR 65942.
Prior to the June 2015 NOPR, DOE issued two notices requesting
comment on the test procedures for cooking products. On January 30,
2013, DOE published a NOPR (``January 2013 TP NOPR'') proposing
amendments to the cooking products test procedure in appendix I that
would allow for the testing of active mode energy consumption of
induction cooking tops; i.e., conventional cooking tops equipped with
induction heating technology for one or more surface units on the
cooking top. 78 FR 6232. DOE proposed to incorporate induction cooking
tops by amending the definition of ``conventional cooking top'' to
include induction heating technology. Furthermore, DOE proposed to
require for all cooking tops the use of test equipment compatible with
induction technology. Specifically, DOE proposed to replace the solid
aluminum test blocks specified at that time in the test procedure for
cooking tops with hybrid test blocks comprising two separate pieces: an
aluminum body and a stainless-steel base. 78 FR 6232, 6234.
On December 3, 2014, DOE issued a second notice requesting comment
on the test procedures for cooking products (``December 2014 TP
SNOPR''). 79 FR 71894. In the December 2014 TP SNOPR, DOE modified its
proposal from the January 2013 TP NOPR in response to comments from
interested parties to specify different test equipment that would allow
for measuring the energy efficiency of induction cooking tops, and
would include an additional test block size for electric surface units
with large diameters (both induction and electric resistance). Id. In
addition, DOE proposed methods to test non-circular electric surface
units, electric surface units with flexible concentric cooking zones,
and full-surface induction cooking tops. Id. In the December 2014 TP
SNOPR, DOE also proposed amendments to add a larger test block size to
test gas cooking top burners with higher input rates. Id.
In the December 2014 TP SNOPR, DOE also proposed methods for
measuring conventional oven volume, clarification that the existing
oven test block must be used to test all ovens regardless of input
rate, and a method to measure the energy consumption and efficiency of
conventional ovens equipped with an oven separator. 79 FR 71894.
On July 2, 2015, DOE published a test procedure final rule (``July
2015 TP Final Rule'') adopting the test procedure amendments discussed
above for conventional ovens only. 80 FR 37954.
As discussed in the June 2015 NOPR for conventional ovens, DOE
received a significant number of comments raising issues with the
repeatability and reproducibility of the proposed hybrid test block
test method for cooking tops in response to the December 2014 TP SNOPR
and in separate interviews conducted with consumer conventional cooking
product manufacturers in February and March of 2015. 80 FR 33030,
33039-33040. A number of manufacturers that produce and sell products
in Europe supported the use of a water-heating test method and
harmonization with IEC Standard 60350-2 Edition 2, ``Household electric
appliances--Part 2: Hobs--Method for measuring performance'' \21\
(``IEC Standard 60350-2'') for measuring the energy consumption of
electric cooking tops. These manufacturers stated that the test methods
in IEC Standard 60350-2 are compatible with all electric cooking top
types, specify additional cookware diameters to account for the variety
of surface unit sizes on the market, and use test loads that represent
real-world cooking top loads. Efficiency advocates also recommended
that DOE require water-heating test methods to produce a measure of
cooking efficiency for conventional cooking tops that is more
representative of actual cooking performance than the hybrid test block
method. 80 FR 33030, 33039-33040. For these reasons, DOE decided to
defer its decision regarding adoption of energy conservation standards
for conventional cooking tops until a representative, repeatable and
reproducible test method for cooking tops was finalized. 80 FR 33030,
33040.
---------------------------------------------------------------------------
\21\ Hob is the British English term for cooking top.
---------------------------------------------------------------------------
DOE published an SNOPR on August 22, 2016 (``August 2016 TP
SNOPR'') that proposed amendments to the test procedures for
conventional cooking tops. 81 FR 57374. Given the feedback from
interested parties discussed above and based on the additional testing
and analysis conducted for the test procedure rulemaking, in the August
2016 TP SNOPR, DOE withdrew its proposal for testing conventional
cooking tops with a hybrid test block. Instead, DOE proposed to amend
its test procedure to incorporate by reference the relevant sections of
European Standard EN 60350-2:2013 ``Household electric cooking
appliances Part 2: Hobs--Methods for measuring performance'' \22\ (``EN
60350-2:2013''), which provide a water-heating test method to measure
the energy consumption of electric cooking tops. The test method
specifies the quantity of water to be heated in a standardized test
vessel whose size is selected based on the diameter of the surface unit
under test. The test vessels specified in EN 60350-2:2013 are
compatible with all cooking top technologies and surface unit diameters
available on the U.S. market. 81 FR 57374, 57381-57384.
---------------------------------------------------------------------------
\22\ The test methods in EN 60350-2:2013 are based on the same
test methods in the draft version of IEC 60350-2 available at the
time of the December 2016 TP Final Rule. As noted in that final
rule, based on the few comments received during the development of
the draft, DOE expected that the IEC procedure, once finalized,
would retain the same basic test method as contained in EN 60350-
2:2013. 81 FR 91418, 91421.
---------------------------------------------------------------------------
DOE also proposed to extend the test methods provided in EN 60530-
2:2013 to measure the energy consumption of gas cooking tops by
correlating test equipment diameter to burner input rate, including
input rates that exceed 14,000 Btu/h. 81 FR 57374, 57385-57386. In
addition, DOE also proposed in the August 2016 TP SNOPR to include
methods for both electric and gas cooking tops to calculate the annual
energy consumption (``AEC'') and integrated annual energy consumption
(``IAEC'') to account for the proposed water-heating test method. 81 FR
57374, 57387-57388. In the August 2016 TP SNOPR, DOE proposed to repeal
the conventional oven test procedure. DOE determined that the
conventional oven test procedure may not accurately represent consumer
use as it favors conventional ovens with low thermal mass and does not
capture cooking performance-related benefits due to increased thermal
mass of the oven cavity. 81 FR 57374, 57378-57379.
[[Page 6831]]
As discussed previously, for the September 2016 SNOPR, DOE
evaluated its proposed energy conservation standards for conventional
cooking tops based on the cooking top test procedure proposed in the
August 2016 TP SNOPR. 81 FR 60784, 60797. For conventional ovens, due
to the uncertainties in analyzing a performance-based standard using
oven testing provisions that DOE proposed to remove from the test
procedure, as discussed previously, DOE proposed in the September 2016
SNOPR prescriptive design requirements for the control system of
conventional ovens. 81 FR 60784, 60794.
On December 16, 2016, DOE published a final rule repealing the test
procedures for conventional ovens, and adopting the test procedure
amendments for conventional cooking tops proposed in the August 2016 TP
SNOPR, with the following modifications:
Aligning the test methods for electric surface units with
flexible concentric cooking zones (also referred to as multi-ring
surface units) with the provisions in EN 60350-2:2013; \23\
---------------------------------------------------------------------------
\23\ EN 60350-2:2013 requires testing of the largest measured
diameter of multi-ring surface units only, unless an additional test
vessel category is needed to meet the test vessel selection
requirements in EN 60350-2:2013. In that case, one of the smaller-
diameter settings of the multi-ring surface unit may be tested if it
fulfills the test vessel category requirement.
---------------------------------------------------------------------------
Clarifying the simmering temperature requirements,
temperature sensor requirements, and surface unit diameter measurement;
and
Maintaining the existing installation requirements in
appendix I. 81 FR 91418.
The Administrative Procedure Act (``APA''), 5 U.S.C. 551 et seq.,
provides among other things, that ``[e]ach agency shall give an
interested person the right to petition for the issuance, amendment, or
repeal of a rule.'' (5 U.S.C. 553(e)) DOE received a petition from AHAM
requesting that DOE reconsider its December 2016 TP Final Rule. In its
petition, AHAM requested that DOE undertake a rulemaking to withdraw
the test procedure for conventional cooking tops, while maintaining the
repeal of the oven test procedure that was part of the December 2016 TP
Final Rule. In the interim, AHAM sought an immediate stay of the
effectiveness of the December 2016 TP Final Rule, including the
requirement that manufacturers use the final test procedure to make
energy-related claims. In its petition, AHAM claimed that its analyses
showed that the test procedure is not representative for gas cooking
tops and, for gas and electric cooking tops, has such a high level of
variation it will not produce accurate results for certification and
enforcement purposes and will not assist consumers in making purchasing
decisions based on energy efficiency. DOE published AHAM's petition on
April 25, 2018, and requested comments and information on whether DOE
should undertake a rulemaking to consider the proposal contained in the
petition. 80 FR 17944.
On August 18, 2020, DOE published a final rule (``August 2020 TP
Final Rule'') withdrawing the test procedure for conventional cooking
tops after evaluating new information and data produced by AHAM and
other interested parties that suggested that the test procedure yields
inconsistent results that are indicative of the test not being
representative of energy use or efficiency during an average use cycle.
85 FR 50757. Testing conducted by DOE and outside parties using the
test procedure yielded inconsistent results. 85 FR 50757, 50763. DOE
had not identified the cause of the inconsistencies and noted that its
data to date was limited. Id. DOE concluded, therefore, that the test
procedure was not representative of energy use or efficiency during an
average use cycle. Id. DOE also determined that it would be unduly
burdensome to leave the test procedure in place and require cooking top
tests to be conducted using that test method without further study to
resolve those inconsistencies. Id.
As discussed, DOE published the August 2022 TP Final Rule
establishing a test procedure for conventional cooking tops, at 10 CFR
part 430, subpart B, appendix I1, ``Uniform Test Method for the
Measuring the Energy Consumption of Conventional Cooking Products.'' 87
FR 51492. The test procedure adopted the latest version of the relevant
industry standard published by IEC, Standard 60350-2 (Edition 2.0 2017-
08), ``Household electric cooking appliances--Part 2: Hobs--Methods for
measuring performance'' (``IEC 60350-2:2017''), for electric cooking
tops with modifications including adapting the test method to gas
cooking tops, normalizing the energy use of each test cycle to a
consistent final water temperature, and including a measurement of
standby mode and off mode energy use. Id.
Under EPCA, any new or amended energy conservation standard must
include, where applicable, test procedures prescribed in accordance
with the test procedure provisions of the Act (42 U.S.C. 6295(r)). As
discussed previously, DOE repealed the conventional oven test procedure
and is evaluating new prescriptive design requirements for the control
system of conventional ovens, while proposing to maintain the existing
prescriptive design requirements for conventional gas ovens. As a
result, the prescriptive design requirements would not require
manufacturers to test using the DOE test procedure to certify
conventional ovens.
Furthermore, since DOE is proposing to adopt prescriptive design
requirements that would not require a test procedure for conventional
ovens, DOE tentatively concludes that no test procedures for
conventional ovens are needed at this time. If finalized, this
tentative determination would satisfy the EPCA requirement at 42 U.S.C.
6293(b)(1)(A) that requires the Secretary to review test procedures for
all covered products, including conventional ovens, every 7 years and
either amend those test procedures or publish in the Federal Register
of a determination not to amend the test procedure. The last time the
conventional ovens test procedure was evaluated was as part of the
December 2016 Final Rule, which repealed the existing test procedure
for conventional ovens. Therefore, if DOE were to proceed, it would
need to finalize its determination by December 16, 2023.
AHAM stated that the absence of a test procedure to measure
efficiency for cooking tops and conventional ovens is sufficient
grounds upon which to justify a determination not to amend standards
beyond the existing design standards (AHAM, No. 84 at pp. 2-3). AHAM
added that EPCA does not allow DOE to prescribe amended or new
standards without a final test procedure in place (Id. referencing 42
U.S.C. 6295(o)(3)).
EPCA's requirement that the Secretary may not prescribe an amended
or new standard if a test procedure has not been prescribed does not
apply to dishwashers, clothes washers, clothes dryers, and kitchen
ranges and ovens, the subject of this rulemaking (42 U.S.C.
6295(o)(3)(A)).
AHAM commented that it was working on a test procedure to measure
the efficiency of cooking tops and conventional ovens (AHAM, No. 84 at
p. 3). AHAM added that DOE and some efficiency advocates have been
included in the task force that is developing the test. (Id.) AHAM
stated that the goals of its cooking top and conventional oven test
procedures are to address the technical issues in the previous cooking
top and conventional oven test procedures, which ultimately resulted in
their withdrawal, and to develop new test procedures that are accurate,
repeatable, and reproducible. (Id.) AHAM suggested that DOE would be
[[Page 6832]]
able to adopt both procedures in their entirety in a future rulemaking.
(Id.)
In response to DOE's notification of the White House Office of
Management and Budget (``OMB'') that it would review its withdrawal of
the cooking top test procedure, AHAM urged DOE not to consume its
resources in considering to reinstate the withdrawn cooking top test
procedure and stated that DOE should continue to work with AHAM and
efficiency advocates to develop a new collaborative cooking top test
procedure which would provide certainty as DOE proceeds with a future
standards rulemaking process, shorten the time needed to finalize a
test method, and satisfy the goals of Executive Order 13990. (AHAM, No.
84 at p. 3)
GEA supported DOE's proposed determination not to amend standards
because there is no current test procedure for consumer conventional
cooking products. (GEA, No. 85 at p. 2) GEA stated that the previously
withdrawn test procedures were not reliable or reproducible. (Id.) GEA
stated that it is working closely with the AHAM task force dedicated to
developing a reliable, repeatable, and reproducible test procedure for
consumer conventional cooking products. (Id.)
The Joint Commenters stated that DOE must establish test procedures
for cooking products and complete the revision of the Process Rule
prior to proceeding with a determination for cooking products
standards. (Joint Commenters, No. 87 at p. 1) The Joint Commenters
noted that performance-based standards have the potential to achieve
significantly greater savings than prescriptive requirements, and that
DOE should focus on establishing test procedures rather than use
repealed test procedures to evaluate potential standard levels. (Id.)
NEEA recommended that DOE conduct further testing as needed and
issue updated test procedures for both cooking tops and conventional
ovens, given the significant potential energy savings from performance
standards for both product categories. (NEEA, No. 88 at pp. 1-2) NEEA
recommended that DOE conduct additional testing to resolve the
discrepancies found during former testing and develop a revised test
procedure for conventional cooking tops as soon as possible. (NEEA, No.
88 at p. 2) NEEA stated that all concerns submitted in AHAM's petition
for the withdrawal of the cooking top test procedure (concern over the
lack of defined tolerance for staying ``as close as possible'' to 194
degrees Fahrenheit (``[deg]F'') in the test procedure, variability in
energy consumption during the simmer phase, and variability in
determining the turn down temperature and setting) can be addressed by
setting appropriate tolerances on these variables. (Id.) NEEA further
noted that the test method that was referenced in the 2016 test
procedure, EN 60350-2-2013, has been updated since the December 2016 TP
Final Rule and the revised test method may serve as an additional
resource in developing an updated test procedure that is
representative, repeatable, and reproducible. (NEEA, No. 88 at pp. 2-3)
NEEA recommended that DOE consider ASTM Standard F1521 in updating the
test procedure, which has been used by the Food Service Technology
Center to conduct testing on conventional cooking top performance and
efficiency and is currently being updated for ASTM Committee F26 on
Food Service Equipment. (NEEA, No. 88 at p. 2)
The CA IOUs believe that the withdrawn cooking top test procedure
is adequately repeatable and that it should be re-examined. (CA IOUs,
No. 89 at p. 2) The CA IOUs stated they believe the discrepancies
presented in the AHAM Withdrawal Petition are, in part, due to specific
test method employed during AHAM's testing. (Id.) The CA IOUs continued
that because the test data which was used to withdraw the test
procedure did not use the ambient condition \24\ specifications of the
test procedure in question, DOE should pursue robust round robin
testing to uncover the true reproducibility values associated with the
test procedure. (Id.) In the August 2020 TP Final Rule, DOE cited
authority to withdraw the cooking products test procedure under 42
U.S.C. 6293(b)(3), noting that ``DOE has the authority to withdraw a
test procedure that is not representative of an average use cycle or
period of use and is unduly burdensome to conduct.'' (Id.) In response,
the CA IOUs commented that they believe the authority to act on an
unrepresentative test procedure lies in 42 U.S.C. 6293(b)(2), which
only grants DOE the authority to prescribe or amend a test procedure,
not to withdraw a test procedure in its entirety. (Id.) The CA IOUs
requested that DOE consider reinstating the test procedure and using
the performance-based analysis therein. (Id.)
---------------------------------------------------------------------------
\24\ AHAM's petition noted that some of the test labs
participating in the round robin testing were unable to meet the
ambient conditions of ``2 [deg]F'' specified in the DOE
test procedure, and therefore ran tests at 5 [deg]F in
their laboratories. (EERE-2018-BT-TP-0004-0003) DOE notes that the
test procedure finalized in the December 2016 TP Final Rule required
ambient conditions of 2 [deg]Celsius (``[deg]C''), which
is equivalent to 5 [deg]F, the specification used by
AHAM.
---------------------------------------------------------------------------
DOE acknowledges that a test procedure is necessary to evaluate the
performance of, and to adopt performance standards for, cooking tops.
As discussed previously, since the December 2020 NOPD, DOE has
published a test procedure final rule establishing test procedures for
cooking tops. In this SNOPR, DOE has analyzed performance-based
standards for cooking tops, measured according to new appendix I1.
D. Technological Feasibility
1. General
In each energy conservation standards rulemaking, DOE conducts a
screening analysis based on information gathered on all current
technology options and prototype designs that could improve the
efficiency of the products or equipment that are the subject of the
rulemaking. As the first step in such an analysis, DOE develops a list
of technology options for consideration in consultation with
manufacturers, design engineers, and other interested parties. DOE then
determines which of those means for improving efficiency are
technologically feasible. DOE considers technologies incorporated in
commercially-available products or in working prototypes to be
technologically feasible. Sections 6(b)(3)(i) and 7(b)(1) of appendix
A.
After DOE has determined that particular technology options are
technologically feasible, it further evaluates each technology option
in light of the following additional screening criteria: (1)
practicability to manufacture, install, and service; (2) adverse
impacts on product utility or availability; (3) adverse impacts on
health or safety, and (4) unique-pathway proprietary technologies.
Sections 6(b)(3)(ii)-(v) and 7(b)(2)-(5) of appendix A. Section IV.B of
this document discusses the results of the screening analysis for
consumer conventional cooking products, particularly the designs DOE
considered, those it screened out, and those that are the basis for the
standards considered in this rulemaking. For further details on the
screening analysis for this rulemaking, see chapter 4 of the TSD for
this SNOPR.
2. Maximum Technologically Feasible Levels
When DOE proposes to adopt an amended standard for a type or class
of covered product, it must determine the maximum improvement in energy
efficiency or maximum reduction in
[[Page 6833]]
energy use that is technologically feasible for such product. (42
U.S.C. 6295(p)(1)) Accordingly, in the engineering analysis, DOE
determined the maximum technologically feasible (``max-tech'')
improvements in energy efficiency for consumer conventional cooking
products, using the design parameters for the most efficient products
available on the market or in working prototypes. The max-tech levels
that DOE determined for this rulemaking are described in section IV.C
of this proposed rule and in chapter 5 of the TSD for this SNOPR.
E. Energy Savings
1. Determination of Savings
For each trial standard level (i.e., TSL), DOE projected energy
savings from application of the TSL to consumer conventional cooking
products purchased in the 30-year period that begins in the year of
compliance with the proposed standards (2027-2056).\25\ The savings are
measured over the entire lifetime of consumer conventional cooking
products purchased in the previous 30-year period. DOE quantified the
energy savings attributable to each TSL as the difference in energy
consumption between each standards case and the no-new-standards case.
The no-new-standards case represents a projection of energy consumption
that reflects how the market for a product would likely evolve in the
absence of new or amended energy conservation standards.
---------------------------------------------------------------------------
\25\ Each TSL is composed of specific efficiency levels for each
product class. The TSLs considered for this SNOPR are described in
section V.A of this document. DOE conducted a sensitivity analysis
that considers impacts for products shipped in a 9-year period.
---------------------------------------------------------------------------
DOE used its national impact analysis (``NIA'') spreadsheet model
to estimate national energy savings (``NES'') from potential amended or
new standards for consumer conventional cooking products. The NIA
spreadsheet model (described in section IV.H of this document)
calculates energy savings in terms of site energy, which is the energy
directly consumed by products at the locations where they are used. For
electricity, DOE reports national energy savings in terms of primary
energy savings, which is the savings in the energy that is used to
generate and transmit the site electricity. For natural gas, the
primary energy savings are considered to be equal to the site energy
savings. DOE also calculates NES in terms of FFC energy savings. The
FFC metric includes the energy consumed in extracting, processing, and
transporting primary fuels (i.e., coal, natural gas, petroleum fuels),
and thus presents a more complete picture of the impacts of energy
conservation standards.\26\ DOE's approach is based on the calculation
of an FFC multiplier for each of the energy types used by covered
products or equipment. For more information on FFC energy savings, see
section IV.H.1 of this document.
---------------------------------------------------------------------------
\26\ The FFC metric is discussed in DOE's statement of policy
and notice of policy amendment. 76 FR 51282 (Aug. 18, 2011), as
amended at 77 FR 49701 (Aug. 17, 2012).
---------------------------------------------------------------------------
2. Significance of Savings
To adopt any new or amended standards for a covered product, DOE
must determine that such action would result in significant energy
savings. (42 U.S.C. 6295(o)(3)(B))
The significance of energy savings offered by a new or amended
energy conservation standard cannot be determined without knowledge of
the specific circumstances surrounding a given rulemaking.\27\ For
example, some covered products and equipment have most of their energy
consumption occur during periods of peak energy demand. The impacts of
these products on the energy infrastructure can be more pronounced than
products with relatively constant demand.
---------------------------------------------------------------------------
\27\ The numeric threshold for determining the significance of
energy savings established in a final rule published on February 14,
2020 (85 FR 8626, 8670), was subsequently eliminated in a final rule
published on December 13, 2021 (86 FR 70924).
---------------------------------------------------------------------------
Accordingly, DOE evaluates the significance of energy savings on a
case-by-case basis, taking into account the significance of cumulative
FFC national energy savings, the cumulative FFC emissions reductions,
and the need to confront the global climate crisis, among other
factors. DOE has initially determined the energy savings from the
proposed standard levels are ``significant'' within the meaning of 42
U.S.C. 6295(o)(3)(B).
F. Economic Justification
1. Specific Criteria
As noted previously, EPCA provides seven factors to be evaluated in
determining whether a potential energy conservation standard is
economically justified (42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII)). The
following sections discuss how DOE has addressed each of those seven
factors in this rulemaking.
a. Economic Impact on Manufacturers and Consumers
In determining the impacts of a potential amended standard on
manufacturers, DOE conducts an MIA, as discussed in section IV.J of
this document. DOE first uses an annual cash-flow approach to determine
the quantitative impacts. This step includes both a short-term
assessment--based on the cost and capital requirements during the
period between when a regulation is issued and when entities must
comply with the regulation--and a long-term assessment over a 30-year
period. The industry-wide impacts analyzed include (1) INPV, which
values the industry on the basis of expected future cash flows, (2)
cash flows by year, (3) changes in revenue and income, and (4) other
measures of impact, as appropriate. Second, DOE analyzes and reports
the impacts on different types of manufacturers, including impacts on
small manufacturers. Third, DOE considers the impact of standards on
domestic manufacturer employment and manufacturing capacity, as well as
the potential for standards to result in plant closures and loss of
capital investment. Finally, DOE takes into account cumulative impacts
of various DOE regulations and other regulatory requirements on
manufacturers.
For individual consumers, measures of economic impact include the
changes in LCC and PBP associated with new or amended standards. These
measures are discussed further in the following section. For consumers
in the aggregate, DOE also calculates the national net present value of
the consumer costs and benefits expected to result from particular
standards. DOE also evaluates the impacts of potential standards on
identifiable subgroups of consumers that may be affected
disproportionately by a standard.
b. Savings in Operating Costs Compared to Increase in Price (LCC and
PBP)
EPCA requires DOE to consider the savings in operating costs
throughout the estimated average life of the covered product in the
type (or class) compared to any increase in the price of, or in the
initial charges for, or maintenance expenses of, the covered product
that are likely to result from a standard. (42 U.S.C.
6295(o)(2)(B)(i)(II)) DOE conducts this comparison in its LCC and PBP
analysis.
The LCC is the sum of the purchase price of a product (including
its installation) and the operating expense (including energy,
maintenance, and repair expenditures) discounted over the lifetime of
the product. The LCC analysis requires a variety of inputs, such as
product prices, product energy consumption, energy prices, maintenance
and repair costs, product lifetime, and discount rates appropriate for
consumers. To account for uncertainty and variability in specific
[[Page 6834]]
inputs, such as product lifetime and discount rate, DOE uses a
distribution of values, with probabilities attached to each value.
The PBP is the estimated amount of time (in years) it takes
consumers to recover the increased purchase cost (including
installation) of a more-efficient product through lower operating
costs. DOE calculates the PBP by dividing the change in purchase cost
due to a more-stringent standard by the change in annual operating cost
for the year that standards are assumed to take effect.
For its LCC and PBP analysis, DOE assumes that consumers will
purchase the covered products in the first year of compliance with new
or amended standards. The LCC savings for the considered efficiency
levels are calculated relative to the case that reflects projected
market trends in the absence of new or amended standards. DOE's LCC and
PBP analysis is discussed in further detail in section IV.F of this
document.
c. Energy Savings
Although significant conservation of energy is a separate statutory
requirement for adopting an energy conservation standard, EPCA requires
DOE, in determining the economic justification of a standard, to
consider the total projected energy savings that are expected to result
directly from the standard. (42 U.S.C. 6295(o)(2)(B)(i)(III)) As
discussed in section III.E of this document, DOE uses the NIA
spreadsheet models to project national energy savings.
d. Lessening of Utility or Performance of Products
In establishing product classes and in evaluating design options
and the impact of potential standard levels, DOE evaluates potential
standards that would not lessen the utility or performance of the
considered products. (42 U.S.C. 6295(o)(2)(B)(i)(IV)) Based on data
available to DOE, the standards proposed in this document would not
reduce the utility or performance of the products under consideration
in this rulemaking.
e. Impact of Any Lessening of Competition
EPCA directs DOE to consider the impact of any lessening of
competition, as determined in writing by the Attorney General, that is
likely to result from a proposed standard. (42 U.S.C.
6295(o)(2)(B)(i)(V)) It also directs the Attorney General to determine
the impact, if any, of any lessening of competition likely to result
from a proposed standard and to transmit such determination to the
Secretary within 60 days of the publication of a proposed rule,
together with an analysis of the nature and extent of the impact. (42
U.S.C. 6295(o)(2)(B)(ii)) DOE will transmit a copy of this proposed
rule to the Attorney General with a request that the Department of
Justice (``DOJ'') provide its determination on this issue. DOE will
publish and respond to the Attorney General's determination in the
final rule. DOE invites comment from the public regarding the
competitive impacts that are likely to result from this proposed rule.
In addition, stakeholders may also provide comments separately to DOJ
regarding these potential impacts. See the ADDRESSES section for
information to send comments to DOJ.
f. Need for National Energy Conservation
DOE also considers the need for national energy and water
conservation in determining whether a new or amended standard is
economically justified. (42 U.S.C. 6295(o)(2)(B)(i)(VI)) The energy
savings from the proposed standards are likely to provide improvements
to the security and reliability of the Nation's energy system.
Reductions in the demand for electricity also may result in reduced
costs for maintaining the reliability of the Nation's electricity
system. DOE conducts a utility impact analysis to estimate how
standards may affect the Nation's needed power generation capacity, as
discussed in section IV.M of this document.
DOE maintains that environmental and public health benefits
associated with the more efficient use of energy are important to take
into account when considering the need for national energy
conservation. The proposed standards are likely to result in
environmental benefits in the form of reduced emissions of air
pollutants and greenhouse gases associated with energy production and
use, including in-home emissions reductions experienced by consumers,
and their families. DOE conducts an emissions analysis to estimate how
potential standards may affect these emissions, as discussed in section
IV.K of this document; the estimated emissions impacts are reported in
section V.B.6 of this document. DOE also estimates the economic value
of climate and health benefits from certain emissions reductions
resulting from the considered TSLs, as discussed in section IV.L of
this document.
g. Other Factors
In determining whether an energy conservation standard is
economically justified, DOE may consider any other factors that the
Secretary deems to be relevant. (42 U.S.C. 6295(o)(2)(B)(i)(VII)) To
the extent DOE identifies any relevant information regarding economic
justification that does not fit into the other categories described
previously, DOE could consider such information under ``other
factors.''
2. Rebuttable Presumption
As set forth in 42 U.S.C. 6295(o)(2)(B)(iii), EPCA creates a
rebuttable presumption that an energy conservation standard is
economically justified if the additional cost to the consumer of a
product that meets the standard is less than three times the value of
the first year's energy savings resulting from the standard, as
calculated under the applicable DOE test procedure. DOE's LCC and PBP
analyses generate values used to calculate the effects that proposed
energy conservation standards would have on the payback period for
consumers. These analyses include, but are not limited to, the 3-year
payback period contemplated under the rebuttable-presumption test. In
addition, DOE routinely conducts an economic analysis that considers
the full range of impacts to consumers, manufacturers, the Nation, and
the environment, as required under 42 U.S.C. 6295(o)(2)(B)(i). The
results of this analysis serve as the basis for DOE's evaluation of the
economic justification for a potential standard level (thereby
supporting or rebutting the results of any preliminary determination of
economic justification). The rebuttable presumption payback calculation
is discussed in section IV.F.9 of this proposed rule.
IV. Methodology and Discussion of Related Comments
This section addresses the analyses DOE has performed for this
rulemaking with regard to consumer conventional cooking products.
Separate paragraphs address each component of DOE's analyses.
DOE used several analytical tools to estimate the impact of the
standards proposed in this document. The first tool is a spreadsheet
that calculates the LCC savings and PBP of potential amended or new
energy conservation standards. The national impacts analysis uses a
second spreadsheet set that provides shipments projections and
calculates national energy savings and net present value of total
consumer
[[Page 6835]]
costs and savings expected to result from potential energy conservation
standards. DOE uses the third spreadsheet tool, the Government
Regulatory Impact Model (``GRIM''), to assess manufacturer impacts of
potential standards. These three spreadsheet tools are available on the
DOE website for this rulemaking: www.regulations.gov/docket/EERE-2014-BT-STD-0005/document. Additionally, DOE used output from the latest
version of the Energy Information Administration's (``EIA's'') Annual
Energy Outlook (``AEO''), a widely known energy projection for the
United States, for the emissions and utility impact analyses.
A. Market and Technology Assessment
DOE develops information in the market and technology assessment
that provides an overall picture of the market for the products
concerned, including the purpose of the products, the industry
structure, manufacturers, market characteristics, and technologies used
in the products. This activity includes both quantitative and
qualitative assessments, based primarily on publicly available
information. The subjects addressed in the market and technology
assessment for this rulemaking include (1) a determination of the scope
of the rulemaking and product classes, (2) manufacturers and industry
structure, (3) existing efficiency programs, (4) shipments information,
(5) market and industry trends; and (6) technologies or design options
that could improve the energy efficiency of consumer conventional
cooking products. The key findings of DOE's market assessment are
summarized in the following sections. See chapter 3 of the TSD for this
SNOPR for further discussion of the market and technology assessment.
1. Product Classes
When evaluating and establishing energy conservation standards, DOE
may establish separate standards for a group of covered products (i.e.,
establish a separate product class) if DOE determines that separate
standards are justified based on the type of energy used, or if DOE
determines that a product's capacity or other performance-related
features that justifies a different standard. (42 U.S.C. 6295(q)) In
making a determination whether a performance-related feature justifies
a different standard, DOE must consider such factors as the utility to
the consumer of the feature and other factors DOE determines are
appropriate. (Id.)
a. Conventional Cooking Tops
During the previous energy conservation standards rulemaking for
cooking products, DOE evaluated product classes for conventional
cooking tops based on energy source (i.e., gas or electric). These
distinctions initially yielded two conventional cooking top classes:
(1) gas cooking tops; and (2) electric cooking tops. For electric
cooking tops, DOE determined that the ease of cleaning smooth elements
provides enhanced consumer utility over coil elements. Because smooth
elements can use more energy than coil elements, DOE defined two
separate product classes for electric cooking tops. DOE defined the
following product classes for consumer conventional cooking tops in the
April 2009 Final Rule TSD (``2009 TSD''): \28\
---------------------------------------------------------------------------
\28\ The TSD from the previous residential cooking products
standards rulemaking is available at: www.regulations.gov/docket/EERE-2006-STD-0127/document.
---------------------------------------------------------------------------
Electric cooking tops--low or high wattage open (coil)
elements;
Electric cooking tops--smooth elements; and
Gas cooking tops--conventional burners.
Induction Heating
In the December 2020 NOPD, DOE proposed to maintain the product
classes for conventional cooking tops from the previous standards
rulemaking, as discussed. 85 FR 80982, 80995. DOE also proposed to
consider induction heating as a technology option for electric smooth
element cooking tops rather than as a separate product class. Id. DOE
noted that induction heating provides the same basic function of
cooking or heating food as heating by gas flame or electric resistance,
and that the installation options available to consumers are also the
same for both cooking products with induction and with electric
resistance heating. Id. In addition, in considering whether there are
any performance-related features that justify a higher energy use
standard to establish a separate product class, DOE noted in the
September 2016 SNOPR that the utility of speed of cooking, ease of
cleaning, and requirements for specific cookware for induction cooking
tops do not appear to be uniquely associated with higher energy use
compared to other electric smooth element cooking tops with electric
resistance heating elements. 81 FR 60784, 60801.
DOE did not receive any comments regarding induction technologies
in response to the December 2020 NOPD.
In addition to the reasons presented in the December 2020 NOPD and
discussed previously, DOE recognizes that induction cooking tops are
only compatible with ferromagnetic cooking vessels. However, DOE does
not identify any consumer utility unique to any specific type of
cookware that would warrant establishing separate product classes. As
discussed in chapter 8 of the TSD for this SNOPR, DOE considered the
cost of replacing cookware as part of the LCC analysis. DOE also
conducted standby testing on full-surface induction cooking tops. Based
on DOE's testing, the sensors required to detect the presence of a pot
placed on the cooking surface do not remain active while the product is
in standby mode. In addition, DOE notes that the standby power required
for the tested model (0.25 watts (``W'')) was below the average standby
power for other electric cooking tops in DOE's test sample (2.25 W).
For these reasons, DOE is not considering a separate product class for
induction cooking products.
Commercial-Style Cooking Tops
Based on DOE's review of conventional gas cooking tops available on
the market, DOE determined for December 2020 NOPD that products
marketed as commercial-style cannot be distinguished from standard
residential-style products based on performance characteristics or
consumer utility. 85 FR 80982, 80995. While conventional gas cooking
tops marketed as commercial-style have more than one burner rated above
14,000 Btu/h and cast-iron grates, approximately 50 percent of cooking
top models marketed as residential-style also have one or more burners
rated above 14,000 Btu/h and cast-iron grates. Id.
As part of the December 2020 NOPD, DOE considered whether separate
product classes for commercial-style gas cooking tops with higher
burner input rates are warranted by comparing the test energy
consumption of individual surface units in a sample of cooking tops
tested by DOE. Id. For the September 2016 SNOPR analysis, DOE conducted
testing of gas surface units in a sample of twelve gas cooking tops,
which included six products marketed as commercial-style, according to
the test procedure established in the December 2016 TP Final Rule and
determined that there was no statistically significant correlation
between burner input rate and the ratio of surface unit energy
consumption to
[[Page 6836]]
test load mass \29\ for cooking tops marketed as either residential-
style or commercial-style. 81 FR 60783, 60801-60802. DOE noted that its
testing showed that this efficiency ratio for gas cooking tops is more
closely related to burner and grate design rather than input rate. Id.
at 81 FR 60802.
---------------------------------------------------------------------------
\29\ Because the mass of the test load depends on the input rate
of the burner, the test energy consumption must be normalized for
comparison. The higher the ratio of test energy consumption to test
load mass, the less efficient the surface unit.
---------------------------------------------------------------------------
DOE recognized in the December 2020 NOPD that the presence of
certain features, such as heavy cast-iron grates and multiple high-
input rate burners (``HIR burners''), may help consumers perceive a
difference between commercial-style and residential-style gas cooking
top performance. 85 FR 80982, 80996. However, DOE stated that it was
not aware of clearly defined and consistent design differences and
corresponding utility provided by commercial-style gas cooking tops as
compared to residential-style gas cooking tops. Id. Although DOE's
testing indicated there is a difference in energy consumption between
residential-style and commercial-style gas cooking tops, this
difference could not be correlated to any specific utility provided to
consumers. Id. Moreover, DOE stated that it is not aware of an industry
test standard that evaluates cooking performance and that would
quantify the utility provided by these products. Id. While DOE stated
in the December 2020 NOPD that it recognizes the presence of certain
commercial-style features described by manufacturers may allow
consumers to cook with a wide variety of cooking methods, manufacturers
have not provided consumer usage data demonstrating that consumers of
commercial-style cooking tops and residential-style cooking tops employ
significantly different cooking methods during a typical cooking cycle.
Id. Moreover, DOE also stated that manufacturers have not provided
evidence that consumers of commercial-style cooking tops would use more
burners on a cooking top during a single cooking cycle than consumers
of residential-style cooking tops. Id. DOE noted that there are many
residential-style cooking tops with one to two HIR burners and
continuous cast-iron grates that provide consumers with the ability to
sear food at high temperatures and simmer at low temperatures. Id. For
these reasons, DOE did not propose in the December 2020 NOPD to
establish a separate product class for gas cooking tops marketed as
commercial-style or conventional gas cooking tops with higher burner
input rates. Id.
DOE did not receive any comments regarding commercial-style gas
cooking tops in response to the December 2020 NOPD.
For this SNOPR analysis, DOE further considered whether separate
product classes for commercial-style cooking tops are warranted by
comparing the test energy consumption of burners in a sample of cooking
tops tested by DOE according to new appendix I1. DOE measured energy
consumption of gas burners in a sample of 24 gas cooking tops, which
included 11 products marketed as commercial-style. The number of
burners per cooking top ranged from four to six.
DOE's testing, as presented in chapter 5 of the TSD for this SNOPR,
showed that energy consumption for gas cooking tops continues to be
more closely related to burner and grate design rather than input rate,
as it was in the September 2016 SNOPR analysis.
Based on both review of the market and comments from manufacturers,
DOE recognizes that the presence of certain features, such as heavy
cast-iron grates and multiple HIR burners, may help consumers perceive
a difference between commercial-style and residential-style gas cooking
top performance. However, DOE continues to not be aware of clearly
defined, consistent design differences and corresponding utility
provided by commercial-style gas cooking tops as compared to
residential-style gas cooking tops. Although DOE's testing indicates
there is a difference in energy consumption between residential-style
and commercial-style gas cooking tops, this difference could not be
correlated to any specific utility provided to consumers. In addition,
there are many residential-style cooking tops with one to two HIR
burners and continuous cast-iron grates that provide consumers with the
ability to sear food at high temperatures and simmer at low
temperatures. For these reasons, DOE is not evaluating a separate
product class for commercial-style gas cooking tops.
However, as discussed in sections IV.B.1.b and IV.C.1.a of this
document, DOE conducted its engineering analysis consistent with
products currently available on the market and only evaluated
efficiency levels for gas cooking tops that maintain the features
available in conventional cooking tops marketed as commercial-style
(e.g., at least one HIR burners, continuous cast-iron gates, etc.) that
may be used to differentiate these products in the marketplace.
Downdraft Cooking Tops
DOE is aware of conventional cooking tops, including the cooking
top portion of conventional ranges, which incorporate venting systems
which draw air, combustion products, steam, smoke, grease, odors, and
other cooking emissions across the surface of the cooking top and
through a vent ducted to the outdoors (``downdraft venting systems'').
The fan in downdraft venting systems may be activated automatically any
time the cooking top is being operated, through a control algorithm
that determines when the fan should be activated, or by means of
consumer selection. Because indoor air quality (``IAQ'') related to
cooking emissions is the subject of increasing attention and
concern,\30\ and because venting systems designed to specifically
exhaust the emissions from conventional cooking products have been
shown to significantly improve IAQ in homes,\31\ building codes in
certain local jurisdictions mandate the use of venting systems for
conventional cooking products.\32\ Although these venting systems may
be external to and separate from the conventional cooking product
(i.e., a vent hood over a conventional cooking top or a separate
downdraft venting unit built into a countertop), venting may also be
accomplished by means of a downdraft venting system incorporated
integrally in a conventional cooking top. According to DOE's review of
products on the market and discussions with manufacturers, the
prevalence of conventional cooking tops with integral downdraft venting
systems is increasing.
---------------------------------------------------------------------------
\30\ See, for example, the discussion and recommendations
addressing ``Indoor Air Pollution from Cooking'' by the California
Air Resources Board, available at: ww2.arb.ca.gov/resources/documents/indoor-air-pollution-cooking.
\31\ Militello-Hourigan, R.E. and Miller, S.L., ``The impacts of
cooking and an assessment of indoor air quality in Colorado passive
and tightly constructed homes,'' Building and Environment, October
15, 2018. Vol. 144, pp. 573-582. Research indicated that fine
particulate matter (PM2.5) concentrations from cooking
activity in homes could be reduced by at least 75 percent through
the use of a directly exhausting conventional range hood.
\32\ See, for example, Section 15.16.020 ``Domestic Range Hoods
and Vents'' of the San Clemente, California, Mechanical Code, which
requires that ``[k]itchen range hoods shall be installed for cooking
facilities with an approved forced-draft system of ventilation
vented to the outside of the building.''
---------------------------------------------------------------------------
The energy consumption of an integral downdraft venting system,
including the fan and, in some cases, a motor to move the inlet duct
into position during operation, increases the total annual energy
consumption of a conventional cooking top. At this time, DOE does not
have information
[[Page 6837]]
regarding the operating patterns or consumer usage of downdraft venting
systems in conventional cooking tops that would allow it to
characterize representative energy use. Therefore, recognizing the
importance of IAQ issues and rapidly evolving market demands, and so as
to not impede innovation in this area, DOE has not evaluated the energy
consumption of downdraft venting systems nor is proposing to establish
separate product classes for conventional cooking tops with downdraft
venting systems in this SNOPR. DOE will continue to collect information
on such cooking tops and may consider the impacts in a future
rulemaking.
Alternatively, DOE could consider specifying an adder to the
maximum allowable IAEC value in the energy conservation standards for
conventional cooking tops with a downdraft venting system, which would
account for the energy consumption of the fan and any motor operation
during active mode and any standby mode or off mode power consumption
specifically associated with the downdraft venting system.
DOE seeks comment on the impacts of downdraft venting systems on
energy consumption and associated data about such impacts. DOE further
requests comment on its proposal to not include the energy consumption
of any downdraft venting system in the energy conservation standards
for conventional cooking tops.
Single-Zone Conventional Cooking Tops
DOE notes that some conventional cooking tops are distributed in
commerce with only a single cooking zone with a relatively high input
power for electric cooking tops or high burner input rate for gas
cooking tops. Single-cooking zone cooking tops do not provide the
ability for consumers to cook multiple food loads at the same time and,
particularly for gas cooking tops, may not operate over the full range
of input rates associated with all typical cooking processes for which
a conventional cooking top is used (e.g., boiling, saut[eacute]ing,
simmering, reheating) or accommodate the complete range of typical
cookware sizes. To achieve this full functionality, conventional
cooking tops with single cooking zones are typically used in
conjunction with one or more additional conventional cooking tops to
provide the consumer with the choice of the number and type of cooking
zones to use. Indeed, DOE observes that manufacturers of single-zone
cooking tops that are not portable conventional cooking tops also
typically manufacture and market comparable dual-zone cooking tops with
similar construction and design features, and consumers may choose to
install non-portable single-zone cooking units in combination with one
or more of such comparable dual-zone units to achieve full cooking
functionality. As a result, DOE expects that evaluating the IAEC of a
single-zone non-portable cooking top by itself would not be
representative of the average use of the product, and therefore
proposes that a more representative value of IAEC would be based on a
tested configuration of the typical combination of a single-zone
cooking top paired with one or more additional cooking tops, such that
the combination of conventional cooking tops in aggregate provides
complete functionality to the consumer.
Based on DOE's review of commercially available products, single-
zone and dual-zone non-portable cooking tops typically range in width
from 12 inches to 15 inches; DOE therefore proposes that the most
representative pairing for the tested configuration of a single-zone
cooking top would be the combination of one single-zone cooking top and
one comparable dual-zone cooking top, because the overall width of the
combination would not exceed the width of typical conventional cooking
tops with four to six cooking zones (24 inches to 36 inches) and
because this is the minimum number of such cooking tops that would
ensure complete functionality as previously described. Based on its
expectation that consumers will select, to the extent possible,
matching products for this combination, DOE proposes to define the
tested configuration of a single-zone non-portable cooking top as the
single-zone unit along with the same manufacturer's dual-zone non-
portable cooking top unit within the same product class and with
similar design characteristics (e.g., construction materials, user
interface), and use the same heating technology (i.e., gas flame,
electric resistive heating, or electric inductive heating) and energy
source (e.g., voltage, gas type). DOE expects that these products
comprising the test configuration typically would be marketed as being
within the same ``product line'' by manufacturers. In instances where
the manufacturer's product line contains more than one dual-zone non-
portable cooking top unit, DOE proposes that the dual-zone unit with
the least energy consumption, as measured using appendix I1, be
selected for the tested configuration, which along with the single-zone
counterpart, would span the full range of expected per-cooking zone
energy efficiency performance.
In the approach DOE is proposing, the representative IAEC of the
single-zone non-portable cooking top would factor in the performance of
the two additional cooking zones included in the dual-zone cooking top
that is part of the tested configuration. That is, the IAEC would be
based on the average active mode performance of the three cooking zones
comprising the tested configuration. Because the single-zone non-
portable cooking top contains one of the three burners, while the
comparable dual-zone cooking top contains two, DOE additionally
proposes that the IAEC of the single-zone non-portable cooking top unit
under consideration be calculated as the weighted average of the
measured IAEC of the single-zone cooking top and the IAEC dual-zone
cooking top in the tested configuration, using the number of cooking
zones as the basis for the weighting factors; i.e., the single-zone
IAEC would have a weighting of \1/3\ and the dual-zone IAEC would have
a weighting of \2/3\. Recognizing that the dual-zone cooking top in the
tested configuration would already be separately tested to determine
its IAEC value for certification purposes, to minimize testing burden
associated with this approach, DOE is proposing that the represented
IAEC value of the dual-zone cooking top (determined separately) would
be used in the calculation of the single-zone cooking top's represented
IAEC value (i.e., DOE is not requiring the dual-zone cooking top to be
tested again for the purpose of determining the represented IAEC value
of the single-zone cooking top). DOE expects that this approach will
produce results that are most representative for the tested
configuration. Further, DOE proposes that if there is no dual-zone non-
portable cooking top within the same product class and with similar
construction and design features as the single-zone non-portable
cooking top being tested, then consumers are likely to purchase and
install the single-zone cooking top for use on its own; in that case,
the most representative IAEC of the single-zone cooking top is the IAEC
of that product as measured according to appendix I1.
DOE requests comment on its proposed tested configuration and
determination of representative IAEC for single-zone non-portable
cooking tops.
DOE additionally proposes that a cooking top basic model is an
individual cooking top model and does not include any combinations of
cooking top models that may be installed together. Accordingly, as part
of DOE's proposal, each individual cooking top model that may be
installed
[[Page 6838]]
in combination must be rated as a separate basic model, and any
combination of such cooking top models that are typically installed in
combination does not itself need to have a separate representation as
its own basic model. In other words, DOE does not expect combinations
to be separately represented or certified to the Department as their
own basic models. This proposal is consistent with the current
definition of a basic model at 10 CFR 430.2, which specifies that basic
model includes all units of a given type of covered product (or class
thereof) manufactured by one manufacturer; having the same primary
energy source; and, which have essentially identical electrical,
physical, and functional (or hydraulic) characteristics that affect
energy consumption, energy efficiency, water consumption, or water
efficiency. Therefore, DOE believes this clarification is helpful to
provide specific context for cooking tops, but DOE is not proposing
specific amendments to the basic model definition in this rule.
DOE requests comment on its proposal to not define ``basic model''
with respect to cooking products or cooking tops, and on possible
definitions for ``basic model'' with respect to cooking products or
cooking tops that could be used if DOE were to determine such a
definition is necessary.
b. Conventional Ovens
During the first energy conservation standards rulemaking for
cooking products, DOE evaluated product classes for conventional ovens
based on energy source (i.e., gas or electric). These distinctions
initially yielded two conventional oven product classes: (1) gas ovens;
and (2) electric ovens. DOE more recently determined that the type of
oven-cleaning system is a utility feature that affects performance. DOE
found that standard ovens and ovens using a catalytic continuous-
cleaning process use roughly the same amount of energy. On the other
hand, self-clean ovens use a pyrolytic process that provides enhanced
consumer utility with lower overall energy consumption as compared to
either standard or catalytically lined ovens. Therefore, in the April
2009 Final Rule analysis described in the 2009 TSD, DOE defined the
following product classes for conventional ovens:
Electric ovens--standard oven with or without a catalytic
line;
Electric ovens--self-clean oven;
Gas ovens--standard oven with or without a catalytic line;
and
Gas ovens--self-clean oven.
Self-Cleaning Technology
Based on DOE's review of conventional gas ovens available on the
U.S. market, and on manufacturer interviews and testing conducted as
part of the engineering analysis, DOE noted in the June 2015 NOPR that
the self-cleaning function of a self-clean oven may employ methods
other than a high-temperature pyrolytic cycle to perform the cleaning
action.\33\ 80 FR 33030, 33043. DOE clarified that a conventional self-
clean electric or gas oven is an oven that has a user-selectable mode
separate from the normal baking mode, not intended to heat or cook
food, which is dedicated to cleaning and removing cooking deposits from
the oven cavity walls. Id. As part of the September 2016 SNOPR, DOE
stated that it is not aware of any differences in consumer behavior in
terms of the frequency of use of the self-clean function that would be
predicated on the type of self-cleaning technology rather than on
cleaning habits or cooking usage patterns that are not dependent on the
type of technology. 81 FR 60784, 60804. As a result, DOE did not
consider establishing separate product classes based on the type of
self-cleaning technology in the December 2020 NOPD. Id.
---------------------------------------------------------------------------
\33\ DOE noted that it is aware of a type of self-cleaning oven
that uses a proprietary oven coating and water to perform a self-
clean cycle with a shorter duration and at a significantly lower
temperature setting. The self-cleaning cycle for these ovens, unlike
catalytically-lined standard ovens that provide continuous cleaning
during normal baking, still have a separate self-cleaning mode that
is user-selectable.
---------------------------------------------------------------------------
For the reasons discussed previously, DOE is not considering
separate product classes based on the type of self-cleaning technology.
DOE welcomes data on the consumer usage patterns of pyrolytic
versus non-pyrolytic self-cleaning functions in conventional ovens, and
requests comment on its preliminary determination that self-cleaning
technologies do not warrant separate product class considerations.
Commercial-Style Ovens
With regard to gas oven burner input rates, DOE noted in the June
2015 NOPR that based on its review of the consumer conventional gas
ovens available on the market, residential-style gas ovens typically
have an input rate of 16,000 to 18,000 Btu/h, whereas residential gas
ovens marketed as commercial-style typically have burner input rates
ranging from 22,500 to 30,000 Btu/h.\34\ 80 FR 33030, 33043. Additional
review of both the residential-style and commercial-style gas oven
cavities indicated that there is significant overlap in oven cavity
volume between the two oven types. Id. Standard residential-style gas
oven cavity volumes range from 2.5 to 5.6 cubic feet (``ft\3\'') and
gas ovens marketed as commercial-style have cavity volumes ranging from
3.0 to 6.0 ft\3\. Id. Sixty percent of the commercial-style models
surveyed had cavity volumes between 4.0 and 5.0 ft\3\, while fifty
percent of the standard models had cavity volumes between 4.0 and 5.0
ft\3\. Id. The primary differentiating factor between the two oven
types was burner input rate, which is greater than 22,500 Btu/h for
commercial-style gas ovens. Id.
---------------------------------------------------------------------------
\34\ However, DOE noted that many gas ranges, while marketed as
commercial- or professional-style and having multiple surface units
with high input rates, did not have a gas oven with a burner input
rate above 22,500 Btu/h.
---------------------------------------------------------------------------
DOE conducted testing for the June 2015 NOPR using the version of
the test procedure later adopted in the July 2015 TP Final Rule to
determine whether commercial-style gas ovens with higher burner input
rates warrant establishing a separate product class. DOE evaluated the
cooking efficiency of eight conventional gas ovens, including five
ovens with burners rated at 18,000 Btu/h or less and the remaining
three with burner input rates ranging from 27,000 Btu/h to 30,000 Btu/
h. Id. DOE's testing showed that the measured cooking efficiencies for
ovens with burner input rates above 22,500 Btu/h were lower than for
ovens with ratings below 22,500 Btu/h, even after normalizing cooking
efficiency to a fixed cavity volume. Id. at 80 FR 33044. DOE also noted
that the conventional gas ovens with higher burner input rates in its
test sample were marketed as commercial-style and had greater total
thermal mass, including heavier racks and thicker cavity walls, even
after normalizing for cavity volume. Id. DOE's testing of a 30,000 Btu/
h oven suggested that much of the energy input to commercial-style
ovens with higher burner input rates goes to heating the added mass of
the cavity, rather than the test load, resulting in relatively lower
measured efficiency when measured according to the test procedure
adopted in the July 2015 TP Final Rule. Id. DOE also investigated the
time it took each oven in the test sample to heat the test load to a
final test temperature of 234 [deg]F above its initial temperature, as
specified in the DOE test procedure in appendix I at the time of the
testing. Id. at 80 FR 33045. DOE's testing showed that gas ovens with
burner input rates greater than 22,500 Btu/h do not heat the test load
significantly faster than the
[[Page 6839]]
ovens with lower burner input rates, and two out of the three units
with the higher burner input rates took longer than the average time to
heat the test load. Id. Therefore, DOE concluded in the June 2015 NOPR
that there is no unique utility associated with faster cook times that
is provided by gas ovens with burner input rates greater than 22,500
Btu/h. Id.
Based on DOE's testing, reverse engineering, and additional
discussions with manufacturers, DOE posited in the June 2015 NOPR that
the major differentiation between conventional gas ovens with lower
burner input rates and those with higher input rates, including those
marketed as commercial-style, was design and construction related to
aesthetics rather than improved cooking performance. Id. Further, DOE
did not identify any unique utility conferred by commercial-style gas
ovens. For the reasons discussed above, DOE did not propose in the June
2015 NOPR to establish a separate product class for conventional gas
ovens with higher burner input rates. Id.
As part of the September 2016 SNOPR, to further address whether
commercial-style ovens provide a unique utility that would warrant
establishing a separate product class, DOE conducted additional
interviews with manufacturers of commercial-style cooking products and
reviewed additional commercial-style test data. 81 FR 60783, 60805-
60806. While these data demonstrated a difference in energy consumption
between residential-style and commercial-style ovens when measured
according to the test procedure adopted in the July 2015 TP Final Rule,
this difference could not be correlated to any specific utility
provided to consumers. Id. at 60806. Moreover, DOE stated that it is
not aware of an industry test standard that evaluates cooking
performance and that would quantify the utility provided by these
products. Id. DOE also noted that all conventional ovens, regardless of
whether or not the product is marketed as commercial-style, must meet
the same safety standards for the construction of the oven. Id.
American National Standards Institute (``ANSI'') Z21.1 ``Household
Cooking Gas Appliances'' (``ANSI Z21.1''), Section 1.21.1, requires
that the oven structure, and specifically the baking racks, have
sufficient strength to sustain a load of up to 25 pounds depending on
the width of the rack. A similar standard (Underwriters Laboratories
(``UL'') 858 ``Household Electric Ranges'' (``UL 858'')) exists for
electric ovens.
DOE also observed as part of the September 2016 SNOPR that many of
the design features identified by manufacturers as unique to
commercial-style ovens and that may impact the energy consumption, such
as extension racks, convection fans, cooling fans, and hidden bake
elements, are also found in residential-style products. 81 FR 60783,
60806. DOE noted that the presence of these features, along with
thicker oven cavity walls and higher burner input rates, may help
consumers perceive a difference between commercial-style and
residential-style ovens. Id. However, DOE stated in the September 2016
SNOPR that it was not aware of a clearly defined and consistent design
difference and corresponding utility provided by commercial-style ovens
as compared to residential-style ovens. Id. For these reasons, DOE did
not propose in the September 2016 SNOPR, or in the December 2020 NOPD
to establish a separate product class for commercial-style ovens. Id.
at 85 FR 80982, 80998.
DOE did not receive any comments on the December 2020 NOPD
regarding commercial-style ovens. Based on DOE's analysis discussed
previously, DOE is not evaluating a separate product class for
commercial-style ovens in this SNOPR.
Installation Configuration
As discussed in section III.C of this document, in the October 2012
TP Final Rule, DOE amended appendix I to include methods for measuring
fan-only mode.\35\ Based on DOE's testing of freestanding, built-in,
and slide-in conventional gas and electric ovens, DOE observed that all
of the built-in and slide-in ovens tested consumed energy in fan-only
mode, whereas freestanding ovens did not. The energy consumption in
fan-only mode for built-in and slide-in ovens ranged from approximately
1.3 to 37.6 watt-hours (``Wh'') per cycle, which corresponds to 0.25 to
7.6 kWh/year. Based on DOE's reverse engineering analyses, DOE noted
that built-in and slide-in products incorporate an additional exhaust
fan and vent assembly that is not present in freestanding products. The
additional energy required to exhaust air from the oven cavity is
necessary for slide-in and built-in installation configurations to meet
safety-related temperature requirements because the oven is enclosed in
cabinetry. For these reasons, DOE proposed in the June 2015 NOPR,
September 2016 SNOPR, and December 2020 NOPD to include separate
product classes for freestanding and built-in/slide-in ovens. 80 FR
33030, 33045; 81 FR 60784, 60806; 85 FR 80982, 80998.
---------------------------------------------------------------------------
\35\ Fan-only mode is an active mode that is not user-selectable
in which a fan circulates air internally or externally to the
cooking product for a finite period of time after the end of the
heating function.
---------------------------------------------------------------------------
DOE did not receive comment on its proposal in the December 2020
NOPD to include separate product classes for built-in/slide-in ovens.
For the reasons discussed above, DOE analyzed separate product classes
for freestanding and built-in/slide-in ovens for this SNOPR.
c. Evaluated Product Classes
In summary, DOE analyzed the product classes listed in Table IV.1
for this SNOPR.

DOE seeks comment on the product classes evaluated in this SNOPR.
2. Technology Options
In the preliminary market analysis and technology assessment, DOE
identified technology options that would be expected to improve the
efficiency of conventional cooking tops and of conventional ovens.
Initially, these technologies encompass all those that DOE believes are
technologically feasible. Chapter 3 of the TSD for this SNOPR includes
the detailed list and descriptions of all technology options identified
for consumer conventional cooking products.
AHAM stated that the available technology options have not changed
since the April 2009 Final Rule. (AHAM, No. 84 at p. 4)
GEA stated there have been no technology improvements impacting
energy efficiency and no meaningful energy savings opportunity in
consumer conventional cooking products since the last standards rule
and therefore there is no justification for changing the current
standards. (GEA, No. 85 at p. 2)
As discussed in chapter 3 of the TSD for this SNOPR, DOE has
performed market research and evaluated available consumer conventional
cooking products to assess existing technology options. Although DOE
has found that there are no specific new technology options that impact
energy efficiency available since the April 2009 Final Rule,
manufacturers are innovating on aspects of cooking performance that do
not relate to efficiency.
a. Conventional Electric Cooking Tops
In response to the September 2016 SNOPR, DOE received comments from
AHAM opposing improved contact conductance as a technology option for
electric open (coil) element cooking tops. AHAM commented that the test
procedure specifies narrow tolerances on the flatness of the test
vessel, which AHAM felt were appropriate to reduce variability in test
results. AHAM stated that if a consumer does not use pots with
comparable flatness, any reduction in energy consumption due to greater
flatness of the heating element that would be measured using the test
procedure will not be realized in the field. Based on its test data,
AHAM asserted that consumers are using warped pans and that improving
the flatness of the heating element will not achieve improved contact
conductance. AHAM stated, therefore, that the energy savings associated
with the improved contact conductance technology option measured under
the test procedure is not representative of what consumer will
experience in the field and, as a result, this should not be considered
as a technology option. (AHAM, No. 64 at pp. 7-10)
DOE agreed that, based on the test data provided by AHAM, improving
the flatness of the electric coil heating element may not result in
energy savings due to the warping of pots and pans used by consumers.
As a result, DOE did not consider improved contact conductance as a
technology option for electric open (coil) element cooking tops for the
December 2020 NOPD. 85 FR 80982, 80999.
In the December 2020 NOPD, DOE proposed to consider the technology
options for conventional electric cooking tops listed in Table IV.2.
Id. at 85 FR 80999-81000.
Table IV.2--December 2020 NOPD Technology Options for Conventional
Electric Cooking Tops
------------------------------------------------------------------------
-------------------------------------------------------------------------
Electric Open (Coil) Element Cooking Tops:
1. None.
Electric Smooth Element Cooking Tops:
1. Halogen elements.
2. Induction elements.
3. Low-standby-loss electronic controls.
------------------------------------------------------------------------
In response to the December 2020 NOPD, the CA IOUs requested that
DOE re-examine its reasoning for no longer considering improved
electric coils as a technology option in electric open (coil) element
cooking tops. (CA IOUs, No. 89 at p. 5) The CA IOUs acknowledged that
pan warping over time is likely to occur, however the CA IOUs do not
believe this should preclude DOE from exploring improved electric coils
as an energy saving option. (Id.) The CA IOUs also expressed doubt that
energy savings from improving contact conductance is non-existent due
to pan warping, stating that AHAM's own data confirms that pan warping
may, in some cases, actually lessen the time it takes for a pot of
water to reach 200 [deg]F on an electric open (coil) element cooking
top. (Id. citing AHAM, No. 64 at p. 9)
DOE agrees that AHAM's data show that pan warping may, in some
cases, lessen the time it takes for a pot of water to reach 200 [deg]F
on an electric open (coil) element cooking top; however, AHAM's data
also demonstrate that in other cases, pan warpage may increase such
heating time. Given the inconsistent relationship between pan warpage
and heat-up time, and the lack of information regarding how cookware
may warp during typical consumer use, manufacturers would be unable to
determine whether any modification to the flatness of their coil
heating elements would improve contact conductance. Therefore, DOE
tentatively concludes that greater flatness of the heating element
would not result in energy savings for consumers, and maintains its
decision to not consider improved contact conductance as a technology
option. DOE is also not aware of any other technology options to
improve electric open (coil) element cooking tops.
For electric open (coil) element cooking tops, in this SNOPR, DOE
did not identify any technology options for improving efficiency.
DOE seeks comment on any existing technologies that improve the
efficiency of electric open (coil) element cooking tops.
For electric smooth element cooking tops, DOE has identified an
additional technology option: reduced air gap. Typical radiant element
cooking tops have an air gap between the heating element and the
ceramic-glass cooking top surface. Energy is expended to heat the air
between the heating element and the glass, with that heated air
providing minimal heating to the cooking vessel. One approach for
increasing the efficiency of a radiant element is to reduce the air gap
to reduce the amount of wasted heat.
For electric smooth element cooking tops, in this SNOPR, DOE
considered the technologies listed in Table IV.3.
Table IV.3--Technology Options for Electric Smooth Element Cooking Tops
------------------------------------------------------------------------
-------------------------------------------------------------------------
1. Halogen elements.
2. Induction elements.
[[Page 6841]]
3. Low-standby-loss electronic controls.
4. Reduced air gap.
------------------------------------------------------------------------
b. Conventional Gas Cooking Tops
In the December 2020 NOPD, DOE proposed to consider the technology
options for conventional gas cooking tops listed in Table IV.4. 85 FR
80982, 80999-81000.
Table IV.4--December 2020 NOPD Technology Options for Conventional Gas
Cooking Tops
------------------------------------------------------------------------
-------------------------------------------------------------------------
1. Radiant gas burners.
2. Catalytic burners.
3. Reduced excess air at burner.
4. Reflective surfaces.
5. Optimized burner and grate design.
------------------------------------------------------------------------
DOE did not receive any comments on the December 2020 NOPD
regarding additional technology options for gas cooking tops.
For gas cooking tops, in this SNOPR, DOE considered the
technologies listed in Table IV.5.
Table IV.5--Technology Options for Conventional Gas Cooking Tops
------------------------------------------------------------------------
-------------------------------------------------------------------------
1. Catalytic burners.
2. Optimized burner and grate design.
3. Radiant gas burners.
4. Reduced excess air at burner.
5. Reflective surfaces.
------------------------------------------------------------------------
c. Conventional Ovens
In the December 2020 NOPD, DOE proposed to consider the technology
options for conventional ovens listed in Table IV.6. 85 FR 80982,
81003.
Table IV.6--December 2020 NOPD Technology Options for Conventional Ovens
------------------------------------------------------------------------
-------------------------------------------------------------------------
1. Bi-radiant oven (electric only).
2. Forced convection.
3. Halogen lamp oven (electric only).
4. Improved and added insulation (standard ovens only).
5. Improved door seals.
6. Low-standby-loss electronic controls.
7. No oven-door window.
8. Oven separator (electric only).
9. Optimized burner and cavity design (gas only).
10. Reduced vent rate (electric standard ovens only).
11. Reflective surfaces.
------------------------------------------------------------------------
Based on review of the additional test data provided by AHAM and
GEA in response to the September 2016 SNOPR, in the December 2020 NOPD,
DOE agreed that replacing the intermittent glo-bar ignition system with
an intermittent/interrupted ignition or intermittent pilot ignition may
not achieve energy savings due to the elimination of heat input that
the glo-bar contributes to the cavity and food load, which must be
offset by additional gas consumption. Id. at 85 FR 81001. As a result,
DOE did not consider intermittent/interrupted or intermittent pilot
ignition systems as a technology option in the December 2020 NOPD. Id.
NEEA recommended that DOE conduct its own testing to verify whether
or not there is an energy savings opportunity from intermittent pilot
ignition systems compared to glo-bar ignition systems. (NEEA, No. 88 at
p. 4)
NEEA has not provided any data or information to suggest that
intermittent pilot ignition systems provide any energy savings compared
to glo-bar ignition systems. DOE continues to agree with AHAM's
theoretical assertion that replacing the intermittent glo-bar ignition
system with an intermittent pilot ignition would eliminate the heat
input that the glo-bar contributes to the cavity and food load, which
must be offset by additional gas consumption. Because this theory is
supported by AHAM's test data, DOE continues to consider that
intermittent pilot ignition systems would not provide energy savings,
and is not considering them as a technology option in this SNOPR.
DOE requests information on the potential energy savings associated
with intermittent pilot ignition systems.
For gas and electric ovens, in this SNOPR, DOE considered the
technologies listed in Table IV.7.
Table IV.7--Technology Options for Conventional Electric and Gas Ovens
------------------------------------------------------------------------
-------------------------------------------------------------------------
1. Bi-radiant oven (electric only).
2. Forced convection.
3. Halogen lamp oven (electric only).
4. Improved and added insulation (standard ovens only).
5. Improved door seals.
6. Low-standby-loss electronic controls.
7. No oven-door window.
8. Optimized burner and cavity design (gas only).
9. Oven separator (electric only).
10. Reduced vent rate (electric standard ovens only).
11. Reflective surfaces.
------------------------------------------------------------------------
B. Screening Analysis
DOE uses the following five screening criteria to determine which
technology options are suitable for further consideration in an energy
conservation standards rulemaking:
(1) Technological feasibility. Technologies that are not
incorporated in commercial products or in commercially viable, existing
prototypes will not be considered further.
(2) Practicability to manufacture, install, and service. If it is
determined that mass production of a technology in commercial products
and reliable installation and servicing of the technology could not be
achieved on the scale necessary to serve the relevant market at the
time of the projected compliance date of the standard, then that
technology will not be considered further.
(3) Impacts on product utility. If a technology is determined to
have a significant adverse impact on the utility of the product to
subgroups of consumers, or result in the unavailability of any covered
product type with performance characteristics (including reliability),
features, sizes, capacities, and volumes that are substantially the
same as products generally available in the United States at the time,
it will not be considered further.
(4) Safety of technologies. If it is determined that a technology
would have significant adverse impacts on health or safety, it will not
be considered further.
(5) Unique-pathway proprietary technologies. If a technology has
proprietary protection and represents a unique pathway to achieving a
given efficiency level, it will not be considered further, due to the
potential for monopolistic concerns.
10 CFR part 430, subpart C, appendix A, sections 6(b)(3) and 7(b).
In summary, if DOE determines that a technology, or a combination
of technologies, fails to meet one or more of the listed five criteria,
it will be excluded from further consideration in the engineering
analysis. The reasons for eliminating any technology are discussed in
the following sections.
The following sections also include comments from interested
parties pertinent to the screening criteria, DOE's evaluation of each
technology option against the screening analysis criteria, and whether
DOE determined that a technology option should be excluded (``screened
out'') based on the screening criteria.
1. Screened-Out Technologies
a. Conventional Electric Cooking Tops
Based on DOE's review of products available on the market and its
product teardowns, DOE stated in the December 2020 NOPD that it is not
aware of any cooking tops that incorporate halogen heating elements.
Id. at 85 FR 81004. Because this technology is currently not being used
commercially or in working prototypes, DOE stated that it does not
believe that it would be practicable to
[[Page 6842]]
produce this technology in commercial products on the scale necessary
to serve the market by the potential compliance date of the proposed
standards. Id. As a result, DOE screened out halogen elements from
further analysis in the December 2020 NOPD. Id.
DOE did not receive any comments on the December 2020 NOPD
regarding the screening analysis for conventional electric cooking
tops.
In this SNOPR, DOE maintains its tentative determination from the
December 2020 NOPD that it would not be practicable to manufacture,
install and service halogen heating elements for electric smooth
element cooking tops on the scale necessary to serve the relevant
market at the time of the effective date of an amended standard, and
screened out this technology from further consideration.
In this SNOPR, DOE is additionally screening out a subset of low-
standby-loss electronic controls, namely those that use ``automatic
power-down'' because this type of low-standby-loss electronic controls
may negatively impact product utility. In particular, it may result in
a loss in the utility of the continuous clock display for combined
cooking products, such as ranges. However, it should be noted that the
other low-standby-loss electronic controls such as switch-mode power
supplies (``SMPSs'') were still analyzed in this SNOPR.
In this SNOPR, DOE is additionally screening out reduced air gap as
a technology option because DOE is aware that the air gaps in
commercialized radiant heating elements are currently as small as is
practicable to manufacture on the scale necessary to serve the cooking
products market. Furthermore, DOE is not aware of the magnitude of
potential energy savings from this technology.
DOE requests comment on the magnitude of potential energy savings
that could result from the use of a reduced air gap as a technology
option.
DOE seeks comment on its screening analysis for conventional
electric cooking tops and whether any additional technology options
should be screened out on the basis of any of the screening criteria in
this SNOPR.
b. Conventional Gas Cooking Tops
For conventional gas cooking tops, in the September 2016 SNOPR and
the December 2020 NOPD, DOE screened out radiant gas burners, catalytic
burners, reduced excess air at burner, and reflective surfaces. 81 FR
60784, 60810-60811; 85 FR 80982, 81003.
In the September 2016 SNOPR, DOE considered different efficiency
levels associated with the optimized burner and grate design technology
option that it observed in products available on the market, including
a range of commercial-style gas cooking tops that maintain the
utilities discussed previously in section IV.A.1.a of this document. 81
FR 60784, 60817. DOE characterized the optimized burner and grate
design incremental efficiency levels based on different observed
features (e.g., HIR burners, grate types and material). Id.
In the December 2020 NOPD, DOE further noted that all gas cooking
tops on the market, including those with an optimized burner and grate
design, have been certified to applicable safety standards. 85 FR
80982, 81004. However, DOE recognized that the estimates for the energy
savings associated with optimized burner and grate design may vary
depending on the test procedure, and thus screened out this technology
option from further analysis of gas cooking tops in the December 2020
NOPD. Id. DOE stated that it would reevaluate the energy savings
associated with this technology option if it considered performance
standards in a future rulemaking. Id.
NEEA recommended that, under an updated test procedure, DOE
continue to evaluate screened out technologies such as optimized burner
and grate design, because NEEA believes this technology option has the
potential to impact efficiency significantly as it affects heat
transfer from the burner to the pot or pan. (NEEA, No. 88 at pp. 3-4)
NEEA recommended that, under an updated test procedure, DOE continue to
evaluate screened out technology options that may improve heat transfer
between the burner and the cooking vessel like the Turbo Pot product
which according to NEEA can improve efficiency by 50 to 60 percent
through a fin design on the pot. (NEEA, No. 88 at p. 4) NEEA recommends
that, under an updated test procedure, DOE continue to evaluate
screened out technology options that improve transfer efficiency
between the burner and the cooking vessel including new burner face
materials (such as metal mesh, ceramics, and metal foam) and power
burners instead of atmospheric burners. (NEEA, No. 88 at p. 4)
The CA IOUs requested that DOE re-examine its reasoning for
screening out optimized grates and burners, because the CA IOUs believe
improvements to this technology could ultimately lead to a non-zero
savings value for gas cooking tops. (CA IOUs, No. 89 at p. 4) The CA
IOUs added that if the withdrawn test procedure is adequate to analyze
the efficiency improvements of grate design, and overall performance
improvement of other product classes' design features, it should not
preclude DOE from considering technologically feasible design
improvements that would improve energy efficiency in gas cooking tops.
(Id.)
As discussed in section III.C of this document, DOE is considering
performance standards for cooking tops, based on new appendix I1.
Therefore, as discussed in the December 2020 NOPD, DOE is reevaluating
the energy savings associated with optimized burner and grate design.
As discussed in chapter 5 of the TSD for this SNOPR, DOE testing has
confirmed that optimizing the burner and grate system can lead to
reduced energy consumption, as measured under appendix I1. Therefore,
DOE is no longer screening out optimized burner and grate design from
its analysis.
However, DOE is aware of a wide range of optimized burner and grate
designs on the market, some of which may reduce the consumer utility
associated with HIR burners and continuous cast-iron grates. In this
SNOPR, DOE is screening out any optimized burner and grate designs that
would reduce consumer utility by only including in its analysis gas
cooking tops that include at least one HIR burner and continuous cast-
iron grates.
In this SNOPR, DOE is continuing to screen out catalytic burners,
radiant gas burners, reduced excess air at burner, and reflective
surfaces, for the same reasons as in the December 2020 NOPD.
DOE seeks comment on its screening analysis for conventional gas
cooking tops and whether any additional technology options should be
screened out on the basis of any of the screening criteria in this
SNOPR.
c. Conventional Ovens
For the same reasons discussed in the September 2016 SNOPR, DOE
screened out added insulation, bi-radiant oven, halogen lamp oven, no
oven door window, reflective surfaces, and optimized burner and cavity
design from further analysis for conventional ovens in the December
2020 NOPD. 81 FR 60784, 60811; 85 FR 80982, 81004.
The Joint Commenters stated that DOE's screening analysis was
inconsistent. (Joint Commenters, No. 87 at p. 2) In particular, the
Joint Commenters noted that technology options like optimized burner
and grate design for gas cooking tops were screened out due to the lack
of a test procedure whereas other technology options that rely on a
test procedure like improved insulation and improved door seals for
conventional ovens were kept
[[Page 6843]]
in the analysis. (Id.) The Joint Commenters added that new test
procedures should be established prior to conducting analysis of
potential standards. (Id.)
As discussed above, DOE is no longer screening out optimized burner
and grate design for gas cooking tops, due to the existence of the new
appendix I1 test procedure.
DOE agrees with the Joint Commenters and recognizes that the
estimates for the energy savings associated with improved insulation,
improved door seals and reduced vent rate may vary depending on the
test procedure, and thus is screening out these technology options from
further analysis of gas cooking tops in this SNOPR. DOE will reevaluate
the energy savings associated with this technology option if it
considers performance standards in a future rulemaking.
For the same reasons as discussed above for conventional electric
cooking tops, DOE is continuing to screen out the use of automatic
power-down low-standby-loss electronic controls. DOE is aware that the
use of automatic power-down low-standby-loss electronic controls may
negatively impact product utility. In particular, the use of automatic
power-down low-standby-loss electronic controls may result in a loss in
the utility of the continuous clock display for ovens. However, it
should be noted that the other low-standby-loss electronic controls
such as SMPSs were still analyzed.
Because DOE did not receive any comments opposing the conventional
oven technology options screened out in the December 2020 NOPD, for the
same reasons discussed in the December 2020 NOPD, DOE is continuing to
screen out added insulation, bi-radiant oven, halogen lamp oven, no
oven door window, reflective surfaces, and optimized burner and cavity
design from further analysis in this SNOPR. DOE continues to seek
comment on the technology options screened out in this SNOPR.
DOE seeks comment on its screening analysis for conventional ovens
and whether any additional technology options should be screened out on
the basis of any of the screening criteria in this SNOPR.
2. Remaining Technologies
Through a review of each technology, DOE tentatively concludes that
all of the other identified technologies listed in section IV.A.2 of
this document met all five screening criteria to be examined further as
design options in DOE's SNOPR analysis. In summary, DOE did not screen
out the technology options listed in Table IV.8.
Table IV.8--Retained Design Options for Consumer Conventional Cooking
Products
------------------------------------------------------------------------
-------------------------------------------------------------------------
Electric Open (Coil) Element Cooking Tops:
None.
Electric Smooth Element Cooking Tops:
1. Induction elements.
2. Switch-mode power supply.
Gas Cooking Tops:
1. Optimized burner and grate design.
Conventional Ovens:
1. Forced convection.
2. Switch-mode power supply.
3. Oven separator (electric only).
------------------------------------------------------------------------
DOE seeks comment on the retained design options for consumer
conventional cooking products.
DOE has initially determined that these technology options are
technologically feasible because they are being used or have previously
been used in commercially available products or working prototypes. DOE
also finds that all of the remaining technology options meet the other
screening criteria (i.e., practicable to manufacture, install, and
service and do not result in adverse impacts on consumer utility,
product availability, health, or safety, unique-pathway proprietary
technologies). For additional details, see chapter 4 of the TSD for
this SNOPR.
C. Engineering Analysis
The purpose of the engineering analysis is to establish the
relationship between the efficiency and cost of consumer conventional
cooking products. There are two elements to consider in the engineering
analysis; the selection of efficiency levels to analyze (i.e., the
``efficiency analysis'') and the determination of product cost at each
efficiency level (i.e., the ``cost analysis''). In determining the
performance of higher-efficiency products, DOE considers technologies
and design option combinations not eliminated by the screening
analysis. For each product class, DOE estimates the baseline cost, as
well as the incremental cost for the product at efficiency levels above
the baseline. The output of the engineering analysis is a set of cost-
efficiency ``curves'' that are used in downstream analyses (i.e., the
LCC and PBP analyses and the NIA).
1. Efficiency Analysis
DOE typically uses one of two approaches to develop energy
efficiency levels for the engineering analysis: (1) relying on observed
efficiency levels in the market (i.e., the efficiency-level approach),
or (2) determining the incremental efficiency improvements associated
with incorporating specific design options to a baseline model (i.e.,
the design-option approach). Using the efficiency-level approach, the
efficiency levels established for the analysis are determined based on
the market distribution of existing products (in other words, based on
the range of efficiencies and efficiency level ``clusters'' that
already exist on the market). Using the design option approach, the
efficiency levels established for the analysis are determined through
detailed engineering calculations and/or computer simulations of the
efficiency improvements from implementing specific design options that
have been identified in the technology assessment. DOE may also rely on
a combination of these two approaches. For example, the efficiency-
level approach (based on actual products on the market) may be extended
using the design option approach to ``gap fill'' levels (to bridge
large gaps between other identified efficiency levels) and/or to
extrapolate to the max-tech level (particularly in cases where the max-
tech level exceeds the maximum efficiency level currently available on
the market).
In this SNOPR, DOE is adopting a design-option approach supported
by testing, supplemented by reverse engineering (physical teardowns and
testing of existing products in the market) to identify the incremental
cost and efficiency improvement associated with each design option or
design option combination. The design-option approach is appropriate
for consumer conventional cooking products, given the lack of
certification data to determine the market distribution of existing
products and to identify efficiency level ``clusters'' that already
exist on the market. DOE also conducted interviews with manufacturers
of consumer conventional cooking products following the February 2014
RFI to develop a deeper understanding of the various combinations of
design options used to increase product efficiency, and their
associated manufacturing costs.
DOE conducted testing and reverse engineering teardowns on products
available on the market. Because there are no performance-based energy
conservation standards or energy reporting requirements for consumer
conventional cooking products, DOE selected test units based on
performance-related features and technologies advertised in product
literature.
For each product/equipment class, DOE generally selects a baseline
model
[[Page 6844]]
as a reference point for each class, and measures changes resulting
from potential energy conservation standards against the baseline. The
baseline model in each product class represents the characteristics of
a product typical of that class (e.g., capacity, physical size).
Generally, a baseline model is one that just meets current energy
conservation standards, or, if no standards are in place, the baseline
is typically the most common or least efficient unit on the market.
For each product class for both conventional cooking tops and
conventional ovens, DOE analyzed several efficiency levels (``ELs'').
As part of DOE's analysis, the maximum available efficiency level is
the highest efficiency unit currently available on the market. DOE also
defines a ``max-tech'' efficiency level to represent the maximum
possible efficiency for a given product.
In response to the September 2016 SNOPR, AHAM commented that the
manufacturer interviews in the earlier stages of the rulemaking have
little or no meaning under the current proposed test procedure. (AHAM,
No. 64 at p. 34-35) AHAM commented that significant changes to DOE's
analysis have occurred since the manufacturer interviews, including (a)
the proposed repeal of the oven test procedure;(b) the proposal of an
entirely different cooking top test procedure; and (c) the entirely
different approach taken to both cooking top and oven standards. (Id.)
AHAM commented that the September 2016 SNOPR was an entirely new
proposal, compared to previous proposals, that was based on a totally
new test procedure with which manufacturers had very little experience.
(Id.)
In the December 2020 NOPD, before the publication of the August
2022 TP Final Rule, DOE was following the then-current version of the
Process Rule which indicated that a NOPD would be warranted due to the
potential energy savings of the economically justified efficiency
levels being below the mandatory threshold level. Therefore, at the
time of the December 2020 NOPD, DOE did not conduct supplemental
manufacturer interviews. Since then, two factors have changed to
justify DOE's current SNOPR: first the Process Rule has been amended
and no longer includes a mandatory threshold, and second, the
publication of the August 2022 TP Final Rule enabled DOE to propose
performance standards for conventional cooking tops which have higher
energy saving potentials than the design requirement standards
considered in the December 2020 NOPD. Accordingly, for this SNOPR, DOE
sought updated manufacturer feedback through confidential interviews on
issues relating to potential energy conservation standards for both
conventional cooking tops and conventional ovens.
a. Conventional Cooking Tops
The December 2020 NOPD was published prior to the August 2022 TP
Final Rule establishing appendix I1, which measures the energy
consumption of conventional cooking tops. In the absence of a test
procedure, the efficiency levels defined in the December 2020 NOPD were
based on prescriptive standards. Therefore, the efficiency levels
defined in the December 2020 NOPD are no longer relevant.
DOE's test sample for this SNOPR included 14 electric cooking tops,
the cooking top portion of 8 electric ranges, 13 gas cooking tops, and
the cooking top portion of 8 gas ranges for a total of 43 consumer
conventional cooking tops covering all of the product classes
considered in this analysis. The test unit characteristics and appendix
I1 test results are available in chapter 5 of the TSD for this SNOPR.
Baseline Efficiency Levels
For this SNOPR, DOE developed performance-based baseline efficiency
levels for consumer conventional cooking tops using the measured energy
consumption of units in the DOE test sample. DOE determined the cooking
top IAEC for each cooking top in the test sample based on the water
heating test procedure adopted in the August 2022 TP Final Rule.
The baseline cooking top efficiency levels for this SNOPR differ
from those presented in the December 2020 NOPD. As discussed, the
cooking top efficiency levels for this SNOPR were determined using the
test procedure finalized in the August 2022 TP Final Rule, whereas the
analysis published in the December 2020 NOPD was based on the test
method adopted in the December 2016 TP Final Rule. As part of the
August 2022 TP Final Rule, DOE defined IAEC using an average of 418
cooking top cycles per year to represent consumer cooking frequency, as
determined using data from the 2015 RECS. By comparison, the December
2016 TP Final Rule used values of 207.5 and 214.5 cooking top cycles
per year for electric and gas cooking tops, respectively, based on the
2009 RECS. Primarily due to the updated number of cooking top cycles
per year (along with some other minor changes to the test procedure),
the baseline IAEC values calculated using the test method finalized in
the August 2022 TP Final Rule are higher than the baseline IAEC values
presented in the December 2020 NOPD.
To establish the new baseline IAEC values for cooking tops, DOE set
the baseline cooking top integrated annual energy consumption (i.e.,
IAEC) equal to the sum of the maximum cooking top active annual energy
consumption (i.e., AEC) observed in the dataset for the analyzed
product class and the maximum combined low-power mode annual energy
consumption (``ETLP'') observed in the dataset for the
analyzed product class. This approach is consistent with the design-
option approach used to determine the incremental efficiency levels, as
discussed further in chapter 5 of TSD for this SNOPR. The consumer
conventional cooking top baseline efficiency levels for this SNOPR,
expressed in kWh/year for electric cooking tops and kBtu/year, are
presented in Table IV.9.
Table IV.9--Consumer Conventional Cooking Top Baseline Efficiency Levels
------------------------------------------------------------------------
Product class IAEC
------------------------------------------------------------------------
Electric Cooking Tops--Open (Coil) 199 kWh/year.
Elements.
Electric Cooking Tops--Smooth Elements. 250 kWh/year.
Gas Cooking Tops....................... 1,775 kBtu/year.
------------------------------------------------------------------------
DOE notes that the efficiency levels for gas cooking tops evaluated
in this SNOPR would replace the current prescriptive standards for gas
cooking tops which prohibits the use of a constant burning pilot light.
As such, DOE's proposed standards for gas cooking tops would be only
performance standards. DOE notes that constant burning pilot lights
consume approximately 2,000 kBtu/year and even the baseline considered
efficiency level of 1,775 kBtu per year for gas cooking tops would not
be achievable by products if they were to incorporate a constant
burning pilot.
DOE seeks comment on the methodology and results for the proposed
baseline efficiency levels for conventional cooking tops.
Incremental Efficiency Levels
i. Electric Cooking Tops
For the electric open (coil) element cooking top product class, DOE
did not identify any design options for reducing IAEC in this SNOPR and
as a result, DOE did not consider any higher efficiency levels above
the baseline.
For electric smooth element cooking tops, as discussed, DOE
measured the
[[Page 6845]]
AEC and ETLP of each cooking top in its test sample for this
SNOPR. DOE then reviewed the AEC and ETLP values for the
electric smooth element cooking tops in its test sample and identified
three higher efficiency levels that can be achieved without sacrificing
clock functionality.
DOE defined EL 1 for electric smooth element cooking tops based on
the low-standby-loss electronic controls design option. As discussed
above, DOE defined the baseline efficiency assuming the highest AEC
would be paired with the highest ETLP observed in its test
sample. DOE is aware of many methods employed by manufacturers to
achieve lower ETLP, including by changing from a linear
power supply to an SMPS, by dimming the control screen's default
brightness, by allowing the clock functionality to turn off after a
period of inactivity, and by removing the clock from the cooking top
altogether. DOE defined EL 1 using the lowest measured ETLP
among the units in its test sample with clock functionality, paired
with the baseline AEC, to avoid any potential loss of utility from
setting a standard based on a unit without clock functionality.
DOE defined EL 2 for electric smooth element cooking tops using the
lowest measured AEC (highest efficiency) among radiant cooking tops in
its sample and the same ETLP as EL 1. DOE notes that, this
AEC value can also be reached by units using induction technology.
To determine the highest measured efficiency for electric smooth
element cooking tops, ``max tech'' or EL 3, DOE calculated the sum of
the lowest measured AEC in its test sample of electric smooth element
cooking tops, which represented induction technology, and the same
ETLP as EL 1.
DOE seeks comment on the methodology and results for the proposed
incremental efficiency levels for electric cooking tops.
ii. Gas Cooking Tops
In the September 2016 SNOPR, DOE considered efficiency levels
associated with optimized burner and grate design for conventional gas
cooking tops. 81 FR 60783, 60817. DOE's testing at the time showed that
energy use was correlated to burner design (e.g., grate weight, flame
angle, distance from burner ports to the cooking surface) and could be
reduced by optimizing the design of the burner and grate system. DOE
reviewed the test data for the conventional gas cooking tops in its
test sample and identified three efficiency levels associated with
improving the burner and grate design. Id.
Although DOE's testing showed that there was no statistically
significant correlation between burner input rate and cooking energy
consumption of the cooking top, DOE noted that cooking tops that
incorporate different combinations of burners, including HIR burners
for larger food loads, have differing capabilities to cook or heat
different sized food loads. As a result, DOE proposed multiple
efficiency levels that took into account key burner configurations. Id.
DOE defined EL 1 in the September 2016 SNOPR based on an optimized
burner and improved grate design of the unit in the test sample with
the lowest measured IAEC among those with cast-iron grates and a six-
surface unit configuration with at least four out of the six surface
units having burner input rates exceeding 14,000 Btu/h. Id. DOE
selected these criteria to maintain the full functionality of cooking
tops marketed as commercial-style. Id. DOE noted that while there are
some such products with fewer than six surface units and fewer than
four HIR burners, DOE did not observe any products marketed as
residential-style with the burner configuration DOE associated with
Efficiency Level 1 of the September 2016 SNOPR. Id.
DOE defined EL 2 in the September 2016 SNOPR based on an optimized
burner and further improved grate design of the unit in the DOE test
sample with the lowest measured IAEC among those units with cast-iron
grates and at least one surface unit having a burner input rate
exceeding 14,000 Btu/h. Id. None of the gas units in the DOE test
sample marketed as commercial-style were capable of achieving this
efficiency level. The cooking tops in the DOE test sample capable of
meeting this efficiency level were marketed as residential-style and
had significantly lighter cast-iron grates than the commercial-style
units. Id.
DOE defined EL 3 (max-tech) in the September 2016 SNOPR based on
the unit in the DOE test sample with the lowest measured IAEC among
those with cast-iron grates, regardless of the number of burners or
burner input rate. Id. DOE noted that the grate weight for this unit
was not lowest in the DOE test sample, confirming that a fully
optimized burner and grate design, and not a reduction in grate weight
alone, is required to improve cooking top efficiency.
In response to the September 2016 SNOPR, AHAM commented that there
were commercial-style products on the market at that time with up to
six HIR burners. AHAM's test data indicated that cooking products
meeting this description were not able to meet DOE's Efficiency Level 1
as proposed in the September 2016 SNOPR. (AHAM, No. 64 at p. 25)
Because DOE's proposed standard level was designed to maintain the full
functionality of commercial-style gas cooking tops, AHAM urged DOE to
propose a less stringent level for gas cooking tops. (AHAM, No. 64 at
p. 28)
DOE has preliminarily determined, as discussed in section IV.B.1.b
of this document, that the utility of commercial-style cooking products
can be met with a single HIR burner. For this SNOPR, DOE considered
efficiency levels associated with optimized burner and grate design,
but only insofar as was not screened out. DOE is aware that some
methods used by gas cooking top manufacturers to achieve lower AEC can
result in a smaller number of HIR burners.\36\ HIR burners provide
unique consumer utility and allow consumers to perform high heat
cooking activities such as searing and stir-frying. DOE is also aware
that some consumers derive utility from continuous cast-iron grates,
such as the ability to use heavy pans, or to shift cookware between
burners without needing to lift them. Because of this, as discussed in
IV.B.1.b of this document, DOE has defined the ELs for gas cooking tops
such that all ELs are achievable with continuous cast-iron grates and
at least one HIR burner.
---------------------------------------------------------------------------
\36\ DOE defines a high-input rate burner as a burner with an
input rate greater than or equal to 14,000 Btu/h.
---------------------------------------------------------------------------
DOE's testing showed that energy use was correlated to burner
design and cooking top configuration (e.g., grate weight, flame angle,
distance from burner ports to the cooking surface) and could be reduced
by optimizing the design of the burner and grate system. DOE reviewed
the test data for the gas cooking tops in its test sample and
identified two efficiency levels associated with improving the burner
and grate design that corresponded to different design criteria. DOE
defined EL 1 and EL 2 for gas cooking tops using the same
ETLP as used for the baseline efficiency level.
DOE seeks comment on the methodology and results for the proposed
incremental efficiency levels for gas cooking tops.
iii. Analyzed Efficiency Levels
As discussed, DOE established efficiency levels for electric smooth
element cooking tops and for gas cooking tops based on combining an AEC
value and an ETLP value associated with specific design
options, noting that different combinations of AEC and ETLP
could be used to meet the IAEC of a
[[Page 6846]]
given efficiency level. Table IV.10 through Table IV.12 show the
efficiency levels for each cooking top product class that are evaluated
in this SNOPR.

b. Conventional Ovens
Potential Prescriptive Standards
As discussed in section III.C of this document, there are no
current test procedures for conventional ovens. Therefore, in this
SNOPR, DOE is considering only efficiency levels corresponding to
prescriptive design requirements as defined by the design options
developed as part of the screening analysis (see section IV.B of this
document): forced convection, the use of a switch-mode power supply,
and an oven separator.
DOE ordered the design options by ease of implementation. Table
IV.13 and Table IV.14 define the efficiency levels analyzed in this
SNOPR for conventional electric and gas ovens, respectively.

------------------------------------------------------------------------
Note: All efficiency levels for conventional gas ovens include the
current prescriptive requirement prohibiting the use of a constant
burning pilot light.
In this SNOPR, DOE is assuming that a baseline conventional oven
uses a linear power supply, based on DOE's analysis of these products.
A linear power supply typically produces unregulated as well as
regulated power. The main characteristic of an unregulated power supply
is that its output may contain significant voltage ripple and that the
output voltage will usually vary with the current drawn. The voltages
produced by regulated power supplies are typically more stable,
exhibiting less ripple than the output from an unregulated power supply
and maintaining a relatively constant voltage within the specified
current limits of the device(s) regulating the power. The unregulated
portion of a linear power supply typically consists of a transformer
that steps AC line voltage down, a voltage rectifier circuit for AC to
DC conversion, and a capacitor to produce unregulated, DC output.
However, there are other means of producing and implementing an
unregulated power supply such as transformerless capacitive and/or
resistive rectification circuits. Within a linear power supply, the
unregulated
[[Page 6847]]
output serves as an input into a single or multiple voltage-regulating
devices. Such regulating devices include Zener diodes, linear voltage
regulators, or similar components which produce a lower-potential,
regulated power output from a higher-potential DC input. This approach
results in a rugged power supply which is reliable, but typically has
an efficiency of about 40 percent.
For EL 1, DOE is analyzing the use of an SMPS rather than a linear
power supply. An SMPS can reduce the standby mode energy consumption
for conventional ovens due to their higher conversion efficiencies of
up to 75 percent in appliance applications for power supply sizes
similar to those of conventional ovens. An SMPS also reduces the no-
load standby losses. In this SNOPR, DOE is considering EL 1 to
correspond to the prescriptive requirement that the conventional oven
not be equipped with a linear power supply.
For EL 2, DOE is analyzing the use of forced convection. A forced
convection oven uses a fan to distribute warm air evenly throughout the
oven cavity. The use of forced circulation can reduce fuel consumption
by cooking food more quickly, at lower temperatures, and in larger
quantities than a natural convection oven of the same size and rating.
Ovens can use convection heating elements in addition to resistance and
other types of elements to speed up the cooking process. By using
different cooking elements where they are most effective, such
combination ovens can reduce the time and energy consumption required
to cook food. As described further in chapter 5 of the TSD for this
SNOPR, DOE performed testing on consumer conventional ovens in support
of this rulemaking to determine the improvement in cooking efficiency
associated with forced convection. Included in the DOE test sample were
four gas ovens and two electric ovens equipped with forced convection.
DOE compared the measured energy consumption of each oven in bake mode
to the average energy consumption of bake mode and convection mode
(including energy consumption due to the fan motor) as specified in the
test procedure. The relative decrease in active mode energy consumption
resulting from the use of forced convection in consumer conventional
ovens ranged from 3.5 to 7.5 percent depending on the product class. In
this SNOPR, DOE is considering EL 2 to correspond to the prescriptive
requirement that the conventional oven be equipped with a convection
fan. This prescriptive requirement would not preclude a non-convection
mode being offered selectable by the consumer.
For EL 3, DOE is analyzing the use of an oven separator, for
electric ovens only.\37\ For loads that do not require the entire oven
volume, an oven separator can be used to reduce the cavity volume that
is used for cooking. With less oven volume to heat, the energy used to
cook an item would be reduced. The oven separator considered here is
the type that can be easily and quickly installed by the user. The side
walls of the oven cavity would be fitted with ``slots'' that guide and
hold the separator into position, and a switch to indicate when the
separator has been installed. The oven would also require at least two
separate heating elements to heat the two cavities. Different pairs of
``slots'' would be spaced throughout the oven cavity so that the user
could select different positions to place the separator. In this SNOPR,
DOE is considering EL 3 to correspond to the prescriptive requirement
that the conventional electric oven be equipped with an oven separator.
---------------------------------------------------------------------------
\37\ Oven separators are not used in conventional gas ovens
because they would interfere with the combustion air flow and
venting requirements for the separate gas burners on the top and
bottom of the oven cavity.
---------------------------------------------------------------------------
DOE seeks comment on the definitions of the proposed efficiency
level for conventional ovens.
Energy Consumption of Baseline Efficiency Level
As noted in the December 2020 NOPD, DOE's test sample for
conventional ovens included one gas wall oven, seven gas ranges, five
electric wall ovens, and two electric ranges for a total of 15
conventional ovens covering all of the considered product classes. DOE
conducted testing according to the test procedure adopted in the July
2015 TP Final Rule. 81 FR 60784, 60812. However, as discussed
previously, in this SNOPR, DOE is considering only efficiency levels
corresponding to prescriptive design requirements. In order to develop
estimated energy consumption rates for each efficiency level, in
support of the Energy Use analysis (see section IV.E of this document),
DOE based its analyses on the data measured using the now-repealed test
procedure.
The integrated annual oven energy consumption (``IEAO''
\38\) for each consumer conventional oven in DOE's test sample was
broken down into its component parts: the energy of active cooking
mode, EAO (including any self-cleaning operation); fan-only
mode, for built-in/slide-in ovens as applicable; and combined low-power
mode, ETLP (including standby mode and off mode).
---------------------------------------------------------------------------
\38\ In this SNOPR, DOE refers to the integrated annual oven
energy consumption using the abbreviation IEAO, rather
than IAEC, as was used in previous documents in this rulemaking.
This change is being made to emphasize the difference between the
IAEC values used for conventional cooking tops which were measured
according to the new appendix I1 and the energy use values used for
conventional ovens which were measured according to the test
procedure as finalized in the July 2015 TP Final Rule.
---------------------------------------------------------------------------
Because oven cooking efficiency and energy consumption depend on
cavity volume, DOE normalized IEAO to a representative
cavity volume of 4.3 ft\3\ using the relationship between energy
consumption and cavity volume discussed in chapter 5 of the TSD for
this SNOPR to allow for more direct comparison between units in the
test sample.
As part of the September 2016 SNOPR, DOE developed energy
consumption values for the baseline efficiency levels for conventional
ovens considering both data from the previous standards rulemaking and
the measured energy use for the test units. DOE conducted testing for
all units in its test sample to measure integrated annual energy
consumption, which included energy use in active mode (including fan-
only mode) and standby mode. 81 FR 60784, 60814. As discussed in the
September 2016 SNOPR, DOE augmented its analysis of electric standard
ovens by considering the energy use of the electric self-clean units in
its test sample, adjusted to account for the differences between
standard-clean and self-clean ovens. Augmenting the electric standard
oven dataset with self-clean models from the DOE test sample allowed
DOE to consider a wider range of cavity volumes in its analysis. 81 FR
60784, 60815. To establish the estimated energy consumption values for
the baseline efficiency levels for conventional ovens, DOE first
derived a relationship between energy consumption and cavity volume.
Using the slope from the previous rulemaking, DOE selected new
intercepts corresponding to the ovens in its test sample with the
lowest efficiency, so that no ovens in the test sample were cut off by
the baseline curve. DOE then set baseline standby energy consumption
for conventional ovens equal to that of the oven (including the oven
component of a range) with the highest standby energy consumption in
DOE's test sample to maintain the full functionality of controls for
consumer utility. In response to the September 2016 SNOPR, DOE did not
receive comment on the baseline efficiency levels considered for
[[Page 6848]]
conventional ovens. 85 FR 80982, 81011. Thus, DOE did not modify the
baseline levels for conventional ovens in the December 2020 NOPD.
As part of the December 2020 NOPD, DOE evaluated the baseline
efficiency levels presented in Table IV.15, which also presents the
energy consumption values for each product class which are based on an
oven with a cavity volume of 4.3 ft\3\. Id.

* IEAO values are normalized based on a 4.3 ft\3\ volume oven.
For this SNOPR, DOE expanded its sample size of conventional ovens
and ranges which were used to determine the baseline ETLP
value. DOE calculated the baseline ETLP using the highest
combined low-power mode measured power on a conventional range with a
linear power supply. DOE also rectified a formula error which was
incorrectly allocating the number of hours in fan-only mode. These
small changes resulted in slightly updated estimated energy consumption
representing the baseline efficiency levels.
The evaluated baseline efficiency levels for consumer conventional
ovens are presented in Table IV.16. After receiving manufacturer
feedback and reviewing products currently on the market, DOE determined
the energy consumption of the baseline efficiency levels based on an
oven with a cavity volume of 4.3 ft\3\ to represent the market-average
cavity volume.

Energy Consumption of Incremental Efficiency Levels
For the September 2016 SNOPR, DOE developed incremental efficiency
levels for each conventional oven product class by first considering
information from the previous rulemaking analysis described in the 2009
TSD. In cases where DOE identified design options during testing and
reverse engineering teardowns, DOE updated the efficiency levels based
on the tested data. 81 FR 60784, 60818. Table IV.17 through Table IV.20
present the efficiency levels for each product class proposed in the
September 2016 SNOPR, along with the associated estimated energy
consumption normalized based on an oven with a cavity volume of 4.3
ft\3\. In response to the September 2016 SNOPR, DOE did not receive
comment on the incremental efficiency levels considered for
conventional ovens. Id. Thus, DOE did not modify the incremental levels
for conventional ovens in the December 2020 NOPD. 85 FR 80982, 81015.

DOE developed the incremental efficiency levels for each design
option identified as a result of the screening analysis. DOE then
developed estimated energy consumption values for each efficiency level
based on test data collected according to the earlier version of the
oven test procedure established in the July 2015 TP Final Rule. The
details of the methodology used to estimate the energy consumption of
each efficiency level for each product class are available in chapter 5
of the TSD for this SNOPR.
DOE's testing of freestanding, built-in, and slide-in installation
configurations for consumer conventional gas and electric ovens
revealed that built-in and slide-in ovens have a fan that consumes
energy in fan-only mode, whereas freestanding ovens do not have such a
fan. For this SNOPR, DOE developed separate energy consumption values
for each installation configuration.
Table IV.21 and Table IV.22 show the efficiency levels for each
consumer conventional oven product class analyzed in this SNOPR. The
IEAO values for each efficiency level are normalized based
on an oven cavity volume of 4.3 ft\3\.

DOE seeks comment on the methodology and results for the estimated
energy use of each proposed efficiency level for conventional ovens.
Energy Use Versus Cavity Volume
The energy consumption of the conventional oven efficiency levels
detailed above are predicated upon ovens with a cavity volume of 4.3
ft\3\. Based on DOE's testing of conventional gas and electric ovens
and discussions with manufacturers, energy use scales with oven cavity
volume due to larger ovens having higher thermal masses and larger
volumes of air (including larger vent rates) than smaller ovens.
Because the DOE test procedure adopted in the July 2015 TP Final Rule
for measuring IEAO uses a fixed test load size, larger ovens
with higher thermal mass will have a higher measured IEAO.
As a result, DOE considered available data to characterize the
relationship between energy use and oven cavity volume.
For the September 2016 SNOPR, DOE established the slopes by first
evaluating the data from the previous rulemaking analysis described in
the 2009 TSD, which presented the relationship between measured energy
factor (``EF'') and cavity volume, then translating from EF to
IEAO, considering the range of cavity volumes for the
majority of products available on the market as well as testing of
units in DOE's test sample. The intercepts for each efficiency level
were then chosen so that the equations passed through the desired
IEAO corresponding to a particular volume. 81 FR 60784,
60821-60822. As part of the analysis for the December 2020 NOPD, DOE
updated the intercepts in the IEAO versus cavity volume
relationships for each product class to reflect the revisions to the
efficiency levels made in that analysis.
In this SNOPR, DOE further updated the efficiency levels, and
associated IEAO intercepts. Additional discussion of DOE's
derivation of the oven IEAO versus cavity volume
relationship is presented in chapter 5 of the TSD for this SNOPR.
2. Cost Analysis
The cost analysis portion of the engineering analysis is conducted
using one or a combination of cost approaches. The selection of cost
approach depends on a suite of factors, including the availability and
reliability of public information, characteristics of the regulated
product, the availability and timeliness of purchasing the product on
the market. The cost approaches are summarized as follows:
Physical teardowns: Under this approach, DOE physically
dismantles a commercially available product, component-by-component, to
develop a detailed bill of materials for the product.
Catalog teardowns: In lieu of physically deconstructing a
product, DOE identifies each component using parts diagrams (available
from manufacturer websites or appliance repair websites, for example)
to develop the bill of materials for the product.
Price surveys: If neither a physical nor catalog teardown
is feasible (for example, for tightly integrated products such as
fluorescent lamps, which are infeasible to disassemble and for which
parts diagrams are unavailable) or cost-prohibitive and otherwise
impractical (e.g., large commercial boilers), DOE conducts price
surveys using publicly available pricing data published on major online
retailer websites and/or by soliciting prices from distributors and
other commercial channels.
In the present case, DOE conducted the analysis using physical and
catalog teardowns. The resulting bill of materials provides the basis
for the manufacturer production cost (``MPC'') estimates.
3. Cost-Efficiency Results
a. Conventional Cooking Tops
For the December 2020 NOPD, DOE maintained its estimates for the
incremental MPCs developed for the September 2016 SNOPR, but adjusted
the cost-efficiency results to reflect updates to parts pricing
estimates and the most recent PPI data. 85 FR 80982, 81018. DOE also
updated the cost-efficiency results to reflect the revised efficiency
levels in that analysis. Id. The estimates for the incremental MPCs
considered in the December 2020 NOPD are presented in Table IV.23.

----------------------------------------------------------------------------------------------------------------
For this SNOPR, DOE developed the cost-efficiency results for each
conventional cooking top product class with incremental efficiency
levels shown in Table IV.24 and Table IV.25. DOE developed incremental
MPCs based on manufacturing cost modeling of units in its sample
featuring the design options.
[[Page 6851]]
As discussed in chapter 5 of the TSD for this SNOPR, DOE evaluated
two versions of the optimized burner and grate design option,
representative of a minimum of either 4 or 1 HIR burners. DOE's testing
showed that decreased energy use could be correlated to burner design
and cooking top configuration (e.g., grate weight, flame angle,
distance from burner ports to the cooking surface). Because this design
option effectively corresponds to a whole burner and grate system re-
design, regardless of the efficiency level achieved by the re-design,
the incremental costs for EL 1 and for EL 2 for gas cooking tops
include the cost for redesigning the combination of each burner and
grate configuration. Therefore, DOE was not able to determine different
incremental costs for EL 1 and EL 2 for gas cooking tops.

estimates and the most recent PPI data. 85 FR 80982, 81019. DOE also
updated the cost-efficiency results to reflect the efficiency levels in

the December 2020 NOPD are presented in Table IV.26.

For this SNOPR, DOE developed the cost-efficiency results for each
conventional oven product class shown in Table IV.27 and Table IV.28.
DOE developed incremental MPCs based on manufacturing cost modeling of
units in its sample featuring the design options. DOE notes that the
estimated incremental MPCs are equivalent for the freestanding and
built-in/slide-in oven product classes and for the standard and self-
clean oven product classes because none of the considered design
options would be implemented differently as a function of installation
configuration or self-clean functionality.

DOE seeks comment on the manufacturer production costs for consumer
conventional cooking products used in this analysis.
4. Manufacturer Selling Price
To account for manufacturers' non-production costs and profit
margin, DOE applies a multiplier (the manufacturer markup) to the MPC.
The resulting manufacturer selling price (``MSP'') is the price at
which the manufacturer distributes a unit into commerce. DOE developed
an average manufacturer markup by examining the annual Securities and
Exchange Commission (``SEC'') 10-K reports filed by publicly traded
manufacturers primarily engaged in appliance manufacturing and whose
combined product range includes consumer conventional cooking products.
See chapter 12 of the TSD for this SNOPR for additional detail on the
manufacturer markup.
D. Markups Analysis
The markups analysis develops appropriate markups (e.g., retailer
markups, distributor markups, contractor markups) in the distribution
chain and sales taxes to convert the MSP estimates derived in the
engineering analysis to consumer prices, which are then used in the LCC
and PBP analysis. At each step in the distribution channel, companies
mark up the price of the product to cover business costs and profit.
For consumer conventional cooking products, the main parties in the
distribution chain are (1) the manufacturers of the products; (2) the
retailers purchasing the products from manufacturers and selling them
to consumers; and (3) the consumers who purchase the products.
For retailers, DOE developed separate markups for baseline products
(baseline markups) and for the incremental cost of more efficient
products (incremental markups). Incremental markups are coefficients
that relate the change in the MSP of higher-efficiency models to the
change in the retailer sales price. Baseline markups are applied to the
price of products with baseline efficiency, while incremental markups
are applied to the difference in price between baseline and higher-
efficiency models (the incremental cost increase). The incremental
markup is typically less than the baseline markup and is designed to
maintain similar per-unit operating profit before and after new or
amended standards.\39\ DOE relied on economic data from the U.S. Census
Bureau to estimate average baseline and incremental markups.\40\
---------------------------------------------------------------------------
\39\ Because the projected price of standards-compliant products
is typically higher than the price of baseline products, using the
same retail markup for the incremental cost and the baseline cost
would result in higher per-unit operating profit for retailers.
While such an outcome is possible, DOE maintains that in markets
that are reasonably competitive it is unlikely that standards would
lead to a sustainable increase in profitability for retailers in the
long run.
\40\ U.S. Census, 2017 Annual Retail Trade Survey (ARTS),
Electronics and Appliance Stores sectors.
---------------------------------------------------------------------------
Based on microeconomic theory, the degree to which firms can pass
along a cost increase depends on the level of market competition,
including variables such as the market structure and conditions on both
the supply and demand sides (e.g., supply and demand elasticity). DOE
examined industry data from IBISWorld and determined the results
suggest that the industry groups involved in appliance retail exhibit a
fair degree of competition even though three firms occupy approximately
85 percent of the market.\41\ However DOE notes that, consumer demand
for household appliances is relatively inelastic (i.e., demand is not
expected to decrease substantially with an increase in the price of
product). Under relatively competitive markets with elastic demand, it
may be tenable for retailers to maintain a fixed markup for a short
period of time after an input price increase, but the market
competition should eventually force them to readjust their markups to
reach a medium-term equilibrium in which per-unit profit is relatively
unchanged before and after standards are implemented. DOE developed the
incremental markup approach based on the widely accepted economic view
that firms are not able to sustain a persistently higher dollar margin
in a competitive market in the medium term. Under competitive market
conditions, if the price of the product increases under standards, the
only way to maintain the same dollar margin as before is for the markup
(and percent gross margin) to decline.

E. Energy Use Analysis
The purpose of the energy use analysis is to determine the annual
energy consumption of consumer conventional cooking products at
different efficiencies in representative U.S. single-family homes,
multi-family residences, and to assess the energy savings potential of
increased consumer conventional cooking product efficiency. The energy
use analysis estimates the range of energy use of consumer conventional
cooking products in the field (i.e., as they are actually used by
consumers). The energy use analysis provides the basis for other
analyses DOE performed, particularly assessments of the energy savings
and the savings in consumer operating costs that could result from
adoption of amended or new standards.
In the December 2020 NOPD, DOE used the 2009 California Residential
Appliance Saturation Survey (``RASS'') and a Florida Solar Energy
Center (``FSEC'') study to establish representative annual energy use
values for conventional cooking tops and ovens.
DOE established a range of energy use from data in the EIA's 2015
Residential Energy Consumption Survey (``RECS 2015'').\42\ RECS 2015
does not provide the annual energy consumption of cooking tops, but it
does provide the frequency of cooking top use.\43\ DOE
[[Page 6853]]
was unable to use the frequency of use to calculate the annual energy
consumption using a bottom-up approach, as data in RECS 2015 did not
include information about the duration of a cooking event to allow for
an annual energy use calculation. For the December 2020 NOPD, DOE
relied on California RASS 2009 and FSEC data to establish the average
annual energy consumption of a conventional cooking top and a
conventional oven.

Administration, Residential Energy Consumption Survey: 2015 RECS

households statistically selected to represent 118.2 million housing
units in the United States. Available at: www.eia.gov/consumption/residential/.
\43\ DOE was unable to use the frequency of use to calculate the
annual energy consumption using a bottom-up approach, as data in
RECS did not include information about the duration of a cooking
event to allow for an annual energy use calculation.
---------------------------------------------------------------------------
From RECS 2015, DOE developed household samples for each product
class. For each household using a conventional cooking top and a
conventional oven, RECS provides data on the frequency of use and
number of meals cooked in the following bins: (1) less than once per
week, (2) once per week, (3) a few times per week, (4) once per day,
(5) two times per day, and (6) three or more times per day. DOE
utilized the frequency of use to define the variability of the annual
energy consumption. First, DOE assumed that the weighted-average
cooking frequency from RECS represents the average energy use values
based on the California RASS and FSEC data. DOE then varied the annual
energy consumption across the RECS households based on their reported
cooking frequency relative to the weighted-average cooking frequency.
AHAM stated that consumer cooking behavior is still the most
significant factor in the energy use of consumer conventional cooking
products. (AHAM, No. 84 at p. 4)
The CA IOUs commented that the COVID-19 pandemic has fundamentally
altered cooking behavior in households across the country. (CA IOUs,
No. 89 at p. 3) The CA IOUs cited a December 2020 survey of more than
1,000 demographically and geographically representative participants
conducted by HUNTER,\44\ in which over 54 percent of responders
reported that they cooked more at home compared to before the pandemic,
with 51-71 percent of responders intending to continue cooking at home,
even after the pandemic is over. (Id.) The CA IOUs also cited a survey
by International Food Information Council,\45\ in which nearly 60
percent of responders stated they are cooking at home more as a result
of the pandemic, and a separate PG&E survey \46\ in which 28 percent of
responders claiming that cooking had been the most likely factor which
contributed to increased energy use in their home during the pandemic.
(Id.) The CA IOUs added that DOE's use of the 2015 RECS to estimate
operating hours for cooking tops does not account for these changing
use trends. (Id.)

DOE agrees that cooking behavior is a significant factor for
determining the energy use of consumer conventional cooking products.
Although, the pandemic has likely introduced changes to consumers
lifestyle, there is insufficient data at this time to establish a
definite trend originating from the pandemic. If appropriate data from
the 2020 RECS are available for the final rule analysis, DOE will
evaluate the extent to which the data may have been affected by changes
in cooking usage due to the pandemic. DOE notes that an increase in
consumer cooking product usage would translate into increased energy
savings and monetized benefits relative to the reference estimates
presented in this SNOPR.
DOE requests comment on data and information on how the pandemic
has changed consumer cooking behavior and product usage.
For this SNOPR, DOE updated the datasets used to establish average
annual energy consumption values for cooking tops and ovens. DOE
utilized the 2019 California RASS \47\ and 2021 field-metered data from
the Pecan Street Project \48\ to estimate representative annual energy
use values for conventional cooking tops and ovens. Pecan Street
measures circuit-level electricity use at 1-minute resolution from
volunteer households across multiple states. From the Pecan Street
data, DOE performed an analysis of 39 households in Texas and 28
households in New York to derive develop average annual energy
consumption values for each State. In the absence of similar field-
metered data for other States, DOE weighted the average annual energy
use results from California (from CA RASS 2019), Texas, and New York by
the number of households in each State to estimate an average National
energy use value more representative than any individual State
measurement. DOE calculated a household-weighted National value using
the average values from Texas, New York, and California and estimates
for the number of households in each State from the U.S. Census.\49\
DOE retained the methodology used in the NOPD to establish a range in
energy use values using RECS 2015.

Chapter 7 of the TSD for this SNOPR provides details on DOE's
energy use analysis for consumer conventional cooking products.
F. Life-Cycle Cost and Payback Period Analysis
DOE conducted LCC and PBP analyses to evaluate the economic impacts
on individual consumers of potential energy conservation standards for
consumer conventional cooking products. The effect of new or amended
energy conservation standards on individual consumers usually involves
a reduction in operating cost and an increase in purchase cost. DOE
used the following two metrics to measure consumer impacts:
The LCC is the total consumer expense of an appliance or
product over the life of that product, consisting of total installed
cost (manufacturer selling price, distribution chain markups, sales
tax, and installation costs) plus operating costs (expenses for energy
use, maintenance, and repair). To compute the operating costs, DOE
discounts future operating costs to the time of purchase and sums them
over the lifetime of the product.
The PBP is the estimated amount of time (in years) it
takes consumers to recover the increased purchase cost (including
installation) of a more-efficient product through lower operating
costs. DOE calculates the PBP by dividing the change in purchase cost
at higher efficiency levels by the change in annual operating cost for
the year that amended or new standards are assumed to take effect.
For any given efficiency level, DOE measures the change in LCC
relative to the LCC in the no-new-standards case, which reflects the
estimated efficiency distribution of consumer conventional cooking
products in the absence of new or amended energy conservation
standards. In contrast, the PBP for a given efficiency level is
measured relative to the baseline product.
For each considered efficiency level in each product class, DOE
calculated the LCC and PBP for a nationally representative set of
housing units. As stated previously, DOE developed household samples
from the 2015 RECS. For each sample household, DOE determined the
energy consumption for the consumer conventional cooking
[[Page 6854]]
products and the appropriate energy price. By developing a
representative sample of households, the analysis captured the
variability in energy consumption and energy prices associated with the
use of consumer conventional cooking products.
Inputs to the calculation of total installed cost include the cost
of the product--which includes MPCs, manufacturer markups, retailer and
distributor markups, and sales taxes--and installation costs. Inputs to
the calculation of operating expenses include annual energy
consumption, energy prices and price projections, repair and
maintenance costs, product lifetimes, and discount rates. DOE created
distributions of values for product lifetime, discount rates, and sales
taxes, with probabilities attached to each value, to account for their
uncertainty and variability.
The computer model DOE uses to calculate the LCC relies on a Monte
Carlo simulation to incorporate uncertainty and variability into the
analysis. The Monte Carlo simulations randomly sample input values from
the probability distributions and consumer conventional cooking product
user samples. For this rulemaking, the Monte Carlo approach is
implemented in MS Excel together with the Crystal BallTM
add-on.\50\ The model calculated the LCC for products at each
efficiency level for 10,000 housing units per simulation run. The
analytical results include a distribution of 10,000 data points showing
the range of LCC savings for a given efficiency level relative to the
no-new-standards case efficiency distribution. In performing an
iteration of the Monte Carlo simulation for a given consumer, product
efficiency is chosen based on its probability. If the chosen product
efficiency is greater than or equal to the efficiency of the standard
level under consideration, the LCC calculation reveals that a consumer
is not impacted by the standard level. By accounting for consumers who
already purchase more-efficient products, DOE avoids overstating the
potential benefits from increasing product efficiency.
---------------------------------------------------------------------------
\50\ Crystal BallTM is commercially available
software tool to facilitate the creation of these types of models by
generating probability distributions and summarizing results within
Excel, available at www.oracle.com/middleware/technologies/crystalball.html (last accessed June 28, 2022).
---------------------------------------------------------------------------
DOE calculated the LCC and PBP for consumers of conventional
cooking products as if each were to purchase a new product in the
expected year of required compliance with new or amended standards. New
and amended standards would apply to consumer conventional cooking
products manufactured 3 years after the date on which any new or
amended standard is published. (42 U.S.C. 6295(m)(4)(A)(i)) At this
time, DOE estimates publication of a final rule in 2023. Therefore, for
purposes of its analysis, DOE used 2027 as the first year of compliance
with any amended standards for consumer conventional cooking products.
Table IV.29 summarizes the approach and data DOE used to derive
inputs to the LCC and PBP calculations. The paragraphs that follow
provide further discussion. Details of the spreadsheet model, and of
all the inputs to the LCC and PBP analyses, are contained in chapter 8
of the TSD for this SNOPR and its appendices.

table or in chapter 8 of the TSD for this SNOPR.
1. Product Cost
To calculate consumer product costs, DOE multiplied the MPCs
developed in the engineering analysis by the markups described
previously (along with sales taxes). DOE used different markups for
baseline products and higher-efficiency products, because DOE applies
an incremental markup to the increase in MSP associated with higher-
efficiency products.
To project future product prices, DOE examined the electric and gas
cooking products Producer Price Index (``PPI''). These indices,
adjusted for inflation, show a declining trend. DOE performed a power-
law fit of historical PPI data and cumulative shipments. For the
electric cooking products price trend, DOE used the ``Electric
household ranges, ovens, surface cooking units and equipment'' PPI for
1967-2021.\51\ For the gas cooking product price trend, DOE used the
``Gas household ranges, ovens, surface cooking units and equipment''
for 1981-2021.\52\ See chapter 8 of the TSD for this SNOPR

2. Installation Cost
Installation cost includes labor, overhead, and any miscellaneous
materials and parts needed to install the product. DOE used data from
the 2021
[[Page 6855]]
RS Means Mechanical Cost Data \53\ on labor requirements to estimate
installation costs for consumer conventional cooking products.
---------------------------------------------------------------------------
\53\ RS Means Company Inc., RS Means Mechanical Cost Data
(2021). Available at https://rsmeans.com (last accessed on June 23,
2022).
---------------------------------------------------------------------------
In general, DOE estimated that installation costs would be the same
for different efficiency levels. In the case of electric smooth element
cooking tops, the induction heating at EL 3 requires a change of
cookware to those that are ferromagnetic to operate the cooking tops in
addition to an upgrade to existing electrical wiring to accommodate for
a higher amperage. DOE treated this as additional installation cost for
this particular design option. DOE used average number of pots and pans
utilized by a representative household to estimate this portion of the
installation cost. See chapter 8 of the TSD for this SNOPR for details
about this component.
3. Annual Energy Consumption
For each sampled household, DOE determined the energy consumption
for a consumer conventional cooking product at different efficiency
levels using the approach described previously in section IV.E of this
document.
4. Energy and Gas Prices
Because marginal electricity price more accurately captures the
incremental savings associated with a change in energy use from higher
efficiency, it provides a better representation of incremental change
in consumer costs than average electricity prices. Therefore, DOE
applied average electricity prices for the energy use of the product
purchased in the no-new-standards case, and marginal electricity prices
for the incremental change in energy use associated with the other
efficiency levels considered.
DOE derived electricity prices in 2021 using data from the Edison
Electric Institute (``EEI'') Typical Bills and Average Rates reports.
Based upon comprehensive, industry-wide surveys, this semi-annual
report presents typical monthly electric bills and average kilowatt-
hour costs to the customer as charged by investor-owned utilities. For
the residential sector, DOE calculated electricity prices using the
methodology described in Coughlin and Beraki (2018).\54\ For the
commercial sector, DOE calculated electricity prices using the
methodology described in Coughlin and Beraki (2019).\55\

DOE's methodology allows electricity prices to vary by sector,
region and season. In the analysis, variability in electricity prices
is chosen to be consistent with the way the consumer economic and
energy use characteristics are defined in the LCC analysis. For
consumer conventional cooking products, DOE calculated weighted-average
values for average and marginal electricity and gas price for the nine
census divisions. See chapter 8 of the TSD for this SNOPR for details.
To estimate energy prices in future years, DOE multiplied the 2021
energy prices by the projection of annual average price changes for
each of the nine census divisions from the Reference case in AEO2022,
which has an end year of 2050.\57\ To estimate price trends after 2050,
DOE used constant value calculated from a simple average of the price
trend between 2046 through 2050.

5. Maintenance and Repair Costs
Repair costs are associated with repairing or replacing product
components that have failed in an appliance; maintenance costs are
associated with maintaining the operation of the product. Typically,
small incremental increases in product efficiency produce no, or only
minor, changes in repair and maintenance costs compared to baseline
efficiency products.
For gas ovens, DOE determined the repair and maintenance costs
associated with glo-bar ignition systems. DOE estimated the average
repair cost attributable to glo-bar systems and annualized it over the
life of the unit at $22.58 based on an analysis of available online
data found on appliance repair costs.
DOE seeks feedback and comment on its estimate for repair costs for
consumer conventional cooking products.
6. Product Lifetime
Equipment lifetime is the age at which the equipment is retired
from service. DOE used a variety of sources to establish low, average,
and high estimates for product lifetime. Additionally, DOE used AHAM's
input to the December 2020 NOPD on the average useful life by product
categories, such as electric range, gas range, wall oven, and electric
cooking top. Utilizing this detail and the market shares of these
product categories, DOE refined the average lifetime estimates to a
more representative 16.8 years for all electric cooking products and
14.5 years for all gas cooking products. DOE characterized the product
lifetimes with Weibull probability distributions.
DOE requests comment and additional data on its estimates for the
lifetime distribution.
See chapter 8 of the TSD for this SNOPR for further details on the
sources used to develop product lifetimes, as well as the use of
Weibull distributions.
7. Discount Rates
In the calculation of LCC, DOE applies discount rates appropriate
to households to estimate the present value of future operating cost
savings. DOE estimated a distribution of discount rates for consumer
conventional cooking products based on the opportunity cost of consumer
funds.
DOE applies weighted average discount rates calculated from
consumer debt and asset data, rather than marginal or implicit discount
rates.\58\ The LCC analysis estimates net present value over the
lifetime of the product, so the appropriate discount rate will reflect
the general opportunity cost of household funds, taking this time scale
into account. Given the long-time horizon modeled in the LCC analysis,
the application of a marginal interest rate associated with an initial
source of funds is inaccurate. Regardless of the method of purchase,
consumers are expected to continue to rebalance their
[[Page 6856]]
debt and asset holdings over the LCC analysis period, based on the
restrictions consumers face in their debt payment requirements and the
relative size of the interest rates available on debts and assets. DOE
estimates the aggregate impact of this rebalancing using the historical
distribution of debts and assets.
---------------------------------------------------------------------------
\58\ The implicit discount rate is inferred from a consumer
purchase decision between two otherwise identical goods with
different first cost and operating cost. It is the interest rate
that equates the increment of first cost to the difference in net
present value of lifetime operating cost, incorporating the
influence of several factors: transaction costs; risk premiums and
response to uncertainty; time preferences; interest rates at which a
consumer is able to borrow or lend. The implicit discount rate is
not appropriate for the LCC analysis because it reflects a range of
factors that influence consumer purchase decisions, rather than the
opportunity cost of the funds that are used in purchases.
---------------------------------------------------------------------------
To establish residential discount rates for the LCC analysis, DOE
identified all relevant household debt or asset classes in order to
approximate a consumer's opportunity cost of funds related to appliance
energy cost savings. It estimated the average percentage shares of the
various types of debt and equity by household income group using data
from the Federal Reserve Board's triennial Survey of Consumer Finances
\59\ (``SCF'') starting in 1995 and ending in 2019. Using the SCF and
other sources, DOE developed a distribution of rates for each type of
debt and asset by income group to represent the rates that may apply in
the year in which amended standards would take effect. DOE assigned
each sample household a specific discount rate drawn from one of the
distributions. The average rate across all types of household debt and
equity and income groups, weighted by the shares of each type, is 4.3
percent. See chapter 8 of the TSD for this SNOPR for further details on
the development of consumer discount rates.

8. Energy Efficiency Distribution in the No-New-Standards Case
To accurately estimate the share of consumers that would be
affected by a potential energy conservation standard at a particular
efficiency level, DOE's LCC analysis considered the projected
distribution (market shares) of product efficiencies under the no-new-
standards case (i.e., the case without amended or new energy
conservation standards) in the compliance year (2027).
For cooking tops, DOE estimated the current efficiency distribution
for each product class from the sample of cooking tops used to develop
the engineering analysis. For ovens, DOE relied on model counts of the
current market distribution. Given the lack of data on historic
efficiency trends, DOE assumed that the estimated current distributions
would apply in 2027.
While DOE acknowledges that economic factors may play a role when
consumers decide on what type of conventional cooking product to
install, assignment of conventional cooking product efficiency for a
given installation, based solely on economic measures such as life-
cycle cost or simple payback period most likely would not fully and
accurately reflect actual real-world installations. There are a number
of market failures discussed in the economics literature that
illustrate how purchasing decisions with respect to energy efficiency
are unlikely to be perfectly correlated with energy use, as described
below. DOE maintains that the method of assignment, which is in part
random, is a reasonable approach, one that simulates behavior in the
conventional cooking product market, where market failures result in
purchasing decisions not being perfectly aligned with economic
interests, more realistically than relying only on apparent cost-
effectiveness criteria derived from the limited information in RECS.
DOE further emphasizes that its approach does not assume that all
purchasers of conventional cooking product make economically irrational
decisions (i.e., the lack of a correlation is not the same as a
negative correlation). As part of the random assignment, some homes or
buildings with more frequent cooking events will be assigned higher
efficiency conventional cooking products, and some homes or buildings
with particularly lower cooking events will be assigned baseline units.
By using this approach, DOE acknowledges the uncertainty inherent in
the data and minimizes any bias in the analysis by using random
assignment, as opposed to assuming certain market conditions that are
unsupported given the available evidence.
First, consumers are motivated by more than simple financial trade-
offs. There are consumers who are willing to pay a premium for more
energy-efficient products because they are environmentally
conscious.\60\ There are also several behavioral factors that can
influence the purchasing decisions of complicated multi-attribute
products, such as conventional cooking products. For example, consumers
(or decision makers in an organization) are highly influenced by choice
architecture, defined as the framing of the decision, the surrounding
circumstances of the purchase, the alternatives available, and how
they're presented for any given choice scenario.\61\ The same consumer
or decision maker may make different choices depending on the
characteristics of the decision context (e.g., the timing of the
purchase), which have nothing to do with the characteristics of the
alternatives themselves or their prices. Consumers or decision makers
also face a variety of other behavioral phenomena including loss
aversion, sensitivity to information salience, and other forms of
bounded rationality.\62\

---------------------------------------------------------------------------
The first of these market failures--the split-incentive or
principal-agent problem--is likely to affect conventional cooking
products more than many other types of appliances. The principal-agent
problem is a market failure that results when the consumer that
purchases the equipment does not internalize all of the costs
associated with operating the equipment. Instead, the user of the
product, who has no control over the purchase decision, pays the
operating costs. There is a high likelihood of split incentive problems
in the case of rental properties where the landlord makes the choice of
what conventional cooking product to install, whereas the renter is
responsible for paying energy bills.
Attari et al.\63\ show that consumers tend to underestimate the
energy use of large energy-intensive appliances, but overestimate the
energy use of small appliances. This may affect how consumers evaluate
and purchase available products on the market. Therefore, it is likely
that consumers systematically underestimate the energy use associated
with conventional cooking products, resulting in less cost-effective
purchases.

DOE seeks comment and feedback on its estimate for the no-new-
standards case efficiency distribution.
9. Payback Period Analysis
The payback period is the amount of time (expressed in years) it
takes the consumer to recover the additional installed cost of more-
efficient products, compared to baseline products, through energy cost
savings. Payback periods that exceed the life of the product mean that
the increased total installed cost is not recovered in reduced
operating expenses.
The inputs to the PBP calculation for each efficiency level are the
change in total installed cost of the product and the change in the
first-year annual operating expenditures relative to the baseline. DOE
refers to this as a ``simple PBP'' because it does not consider changes
over time in operating cost savings. The PBP calculation uses the same
inputs as the LCC analysis when deriving first-year operating costs.
As noted previously, EPCA establishes a rebuttable presumption that
a standard is economically justified if the Secretary finds that the
additional cost to the consumer of purchasing a product complying with
an energy conservation standard level will be less than three times the
value of the first year's energy savings resulting from the standard,
as calculated under the applicable test procedure. (42 U.S.C.
6295(o)(2)(B)(iii)) For each considered efficiency level, DOE
determined the value of the first year's energy savings by calculating
the energy savings in accordance with the applicable DOE test
procedure, and multiplying those savings by the average energy price
projection for the year in which compliance with the new and amended
standards would be required.
G. Shipments Analysis
DOE uses projections of annual product shipments to calculate the
national impacts of potential amended or new energy conservation
standards on energy use, NPV, and future manufacturer cash flows.\65\
The shipments model takes an accounting approach, tracking market
shares of each product class and the vintage of units in the stock.
Stock accounting uses product shipments as inputs to estimate the age
distribution of in-service product stocks for all years. The age
[[Page 6858]]
distribution of in-service product stocks is a key input to
calculations of both the NES and NPV, because operating costs for any
year depend on the age distribution of the stock. The shipment
projections are based on historical data and an analysis of key market
drivers for each product. For consumer conventional cooking products,
DOE accounted for three market segments: (1) new construction, (2)
existing homes (i.e., replacing failed products), and (3) retired but
not replaced products.
---------------------------------------------------------------------------
\65\ DOE uses data on manufacturer shipments as a proxy for
national sales, as aggregate data on sales are lacking. In general,
one would expect a close correspondence between shipments and sales.
---------------------------------------------------------------------------
To determine new construction shipments, DOE used a forecast of new
housing coupled with product market saturation data for new housing.
For new housing completions and mobile home placements, DOE adopted the
projections from EIA's AEO2022 through 2050. For subsequent years, DOE
set the annual new housing completions fixed to the 2050 value. The
market saturation data for new housing was derived from RECS 2015.
DOE estimated replacements using product retirement functions
developed from product lifetimes. DOE used retirement functions based
on Weibull distributions. To reconcile the historical shipments with
modeled shipments, DOE assumed that every retired unit is not replaced.
DOE attributed the reason for this non-replacement to building
demolition occurring over the period 2027-2056. The not-replaced rate
is distributed across electric and gas cooking products.
DOE allocated shipments to each product class based on the current
market share of the class. DOE developed the market shares based on
data collected from Appliance Magazine Market Research report \66\ and
U.S. Appliance Industry Statistical Review.\67\ The product class
market shares are kept constant over time.

Industry: Market Value, Life Expectancy & Replacement Picture 2012.

---------------------------------------------------------------------------
As in the December 2020 NOPD, DOE did not estimate any fuel
switching between electric and gas cooking products, as no significant
switching was observed from historical data between 2003 to 2020.
However, DOE is aware of recent state and local policies promoting the
decarbonization of residential buildings which may impact estimates for
the distribution of shipments between electric and gas cooking products
in the no-new-standards case. Additionally, the Inflation Reduction Act
(IRA) allocates $4.5 billion in rebates to cover the costs of high-
efficiency electric home upgrades, including rebates targeting electric
conventional cooking products. DOE understands that these rebates may
cause the shipments of electric conventional cooking products to
increase and gas conventional cooking products to decline in the no-
new-standards case, thus impacting economic estimates in standards
cases.\68\ Ideally, incorporating the impacts of these policies would
require data on the consumer response rebates covering conventional
cooking products offered through local policies and the IR A rebates.
The implementation and consumer response to these policies is still
nascent and has not yet shown an impact on available shipments data.
However, other forecasts and data may prove useful in informing an
analysis that recognizes the likely sizeable impact the IRA will have
in incentivizing GHG reducing fuel-switching choices among cooking
product consumers, independent of the standards proposed in this
action. DOE will continue to explore possible avenues for such analysis
in anticipation of the final rule. If DOE receives or discovers through
further exploration, information and data (including its own cooking
specific modeling as program designs are established under the IRA),
DOE may consider a sensitivity scenario or other analytic approach
based on comments received on IRA and other policies promoting
electrification.

---------------------------------------------------------------------------
DOE seeks comment on the distribution between electric and gas
cooking products over the shipments analysis period and the potential
for fuel switching between electric and gas cooking products.
Specifically, DOE requests data on existing policy incentives for
consumers to switch fuels and data that indicates the number of
consumers switching fuel types between electric and gas cooking
products.
DOE considered the impact of standards on product shipments. DOE
concluded that it is unlikely that the price increase due to the
proposed standards would impact the decision to install a cooking
product in the new construction market. In the replacement market, DOE
assumed that, in response to an increased product price, some consumers
will choose to repair their old cooking product and extend its lifetime
instead of replacing it immediately. DOE estimated the magnitude of
such impact through a purchase price elasticity of demand. The
estimated price elasticity of -0.367 is based on data for cooking
products as described in appendix 9A of the TSD for this SNOPR. This
elasticity relates the repair or replace decision to the incremental
installed cost of higher efficiency cooking products. DOE estimated
that the average extension of life of the repaired unit would be 5
years, and then that unit will be replaced with a new cooking unit.
The second-hand market for used appliances is a potential
alternative to consumers purchasing a new unit or repairing a broken
unit. An increase in the purchases of older, less-efficient second-hand
units due to a price increase due to a standard could potentially
decrease projected energy savings. DOE assumed that purchases on the
second-hand market would not change significantly due to a standard and
did not include their impact on product shipments.
DOE requests data on the market size and typical selling price of
units sold through the second-hand market for cooking products.
For further details on the shipments analysis, please refer to
chapter 9 of the TSD for this SNOPR.
DOE welcomes input on the effect of new and amended standards on
impacts across products within the same fuel class and equipment type.
DOE seeks comment on the general approach to its shipments
methodology.
H. National Impact Analysis
The NIA assesses the national energy savings (i.e., NES) and the
NPV from a national perspective of total consumer costs and savings
that would be expected to result from new or amended standards at
specific efficiency levels.\69\ (``Consumer'' in this context refers to
consumers of the product being regulated.) DOE calculates the NES and
NPV for the potential standard levels considered based on projections
of annual product shipments, along with the annual energy consumption
and total installed cost data from the energy use and LCC analyses. For
the present analysis, DOE projected the energy savings, operating cost
savings, product costs, and NPV of consumer benefits over the lifetime
of consumer conventional cooking products sold from 2027 through 2056.
---------------------------------------------------------------------------
\69\ The NIA accounts for impacts in the 50 states and U.S.
territories.
---------------------------------------------------------------------------
DOE evaluates the impacts of new or amended standards by comparing
a case without such standards with standards-case projections. The no-
new-standards case characterizes energy use and consumer costs for each
product class in
[[Page 6859]]
the absence of new or amended energy conservation standards. For this
projection, DOE considers historical trends in efficiency and various
forces that are likely to affect the mix of efficiencies over time. DOE
compares the no-new-standards case with projections characterizing the
market for each product class if DOE adopted new or amended standards
at specific energy efficiency levels (i.e., the TSLs or standards
cases) for that class. For the standards cases, DOE considers how a
given standard would likely affect the market shares of products with
efficiencies greater than the standard.
DOE uses a spreadsheet model to calculate the energy savings and
the national consumer costs and savings from each TSL. Interested
parties can review DOE's analyses by changing various input quantities
within the spreadsheet. The NIA spreadsheet model uses typical values
(as opposed to probability distributions) as inputs.
Table IV.33 summarizes the inputs and methods DOE used for the NIA
analysis for the SNOPR. Discussion of these inputs and methods follows
the table. See chapter 10 of the TSD for this SNOPR for further
details.

------------------------------------------------------------------------
1. Product Efficiency Trends
A key component of the NIA is the trend in energy efficiency
projected for the no-new-standards case and each of the standards
cases. Section IV.F.8 of this document describes how DOE developed an
energy efficiency distribution for the no-new-standards case (which
yields a shipment-weighted average efficiency) for each of the
considered product classes for the year of anticipated compliance with
an amended or new standard. DOE assumed a static efficiency
distribution over the shipments analysis period.
For the standards cases, DOE used a ``roll-up'' scenario to
establish the shipment-weighted efficiency for the year that standards
are assumed to become effective (2027). In this scenario, the market
shares of products in the no-new-standards case that do not meet the
standard under consideration would ``roll up'' to meet the new standard
level, and the market share of products above the standard would remain
unchanged.
2. National Energy Savings
The national energy savings analysis involves a comparison of
national energy consumption of the considered products between each
trial standards case (or TSL) and the case with no new or amended
energy conservation standards. DOE calculated the national energy
consumption by multiplying the number of units (stock) of each product
(by vintage or age) by the unit energy consumption (also by vintage).
DOE calculated annual NES based on the difference in national energy
consumption for the no-new standards case and for each higher
efficiency standard case. DOE estimated energy consumption and savings
based on site energy and converted the electricity consumption and
savings to primary energy (i.e., the energy consumed by power plants to
generate site electricity) using annual conversion factors derived from
AEO2022. Cumulative energy savings are the sum of the NES for each year
over the timeframe of the analysis.
Use of higher-efficiency products is sometimes associated with a
direct rebound effect, which refers to an increase in utilization of
the product due to the increase in efficiency. DOE did not find any
data on the rebound effect specific to consumer conventional cooking
products.
DOE seeks feedback on its assumption of no rebound effect
associated with the use of more efficient conventional cooking products
as a result of a standard.
In 2011, in response to the recommendations of a committee on
``Point-of-Use and Full-Fuel-Cycle Measurement Approaches to Energy
Efficiency Standards'' appointed by the National Academy of Sciences,
DOE announced its intention to use FFC measures of energy use and
greenhouse gas and other emissions in the national impact analyses and
emissions analyses included in future energy conservation standards
rulemakings. 76 FR 51281 (Aug. 18, 2011). After evaluating the
approaches discussed in the August 18, 2011 notice, DOE published a
statement of amended policy in which DOE explained its determination
that EIA's National Energy Modeling System (``NEMS'') is the most
appropriate tool for its FFC analysis and its intention to use NEMS for
that purpose. 77 FR 49701 (Aug. 17, 2012). NEMS is a public domain,
multi-sector, partial equilibrium model of the U.S. energy sector \70\
that EIA uses to prepare its Annual Energy Outlook. The FFC factors
incorporate losses in production and delivery in the case of natural
gas (including fugitive emissions) and additional energy used to
produce and deliver the various fuels used by power plants. The
approach used for deriving FFC measures of energy use and emissions is
described in appendix 10B of the TSD for this SNOPR.
---------------------------------------------------------------------------

Modeling System: An Overview 2009, DOE/EIA-0581(2009), October 2009.

---------------------------------------------------------------------------
EEI commented that values for full-fuel-cycle energy estimates for
electricity are extremely overstated,
[[Page 6860]]
especially for consumers in states with renewable portfolio standards.
(EEI, No. 83 at pp. 61-62) EEI added that the values in the December
2020 NOPD use outdated information, are more accurate of a national
average, and are not very representative of what many consumers are
going to see. (Id.) EEI also noted that other standards are
increasingly using regional values. (Id.)
As previously mentioned, DOE converts electricity consumption and
savings to primary energy using annual conversion factors derived from
the AEO. Traditionally, EIA has used the fossil fuel equivalency
approach to report noncombustible renewables' contribution to total
primary energy, in part because the resulting shares of primary energy
are closer to the shares of generated electricity.\71\ The fossil fuel
equivalency approach applies an annualized weighted-average heat rate
for fossil fuel power plants to the electricity generated (in kWh) from
noncombustible renewables. EIA recognizes that using captured energy
(the net energy available for direct consumption after transformation
of a noncombustible renewable energy into electricity) or incident
energy (the mechanical, radiation, or thermal energy that is measurable
as the ``input'' to the device) are possible approaches for converting
renewable electricity to a common measure of primary energy,\72\ but it
continues to use the fossil fuel equivalency approach in the AEO and
other reporting of energy statistics. DOE contends that it is important
for it to maintain consistency with EIA in DOE's accounting of primary
energy savings from energy efficiency standards.
---------------------------------------------------------------------------
\71\ Without adjusting primary energy for fossil fuel
equivalence, the noncombustible renewable share of total energy
consumption for utility-scale electricity generation in 2018 would
have bene 6 percent instead of the 15-percent share under the fossil
fuel equivalency approach. On a physical units basis, net generation
from noncombustible renewable energy sources was 16 percent of total
utility-scale net generation in the same year. www.eia.gov/todayinenergy/detail.php?id=41013 (last accessed June 28, 2022).

---------------------------------------------------------------------------
3. Net Present Value Analysis
The inputs for determining the NPV of the total costs and benefits
experienced by consumers are (1) total annual installed cost, (2) total
annual operating costs (energy costs and repair and maintenance costs),
and (3) a discount factor to calculate the present value of costs and
savings. DOE calculates net savings each year as the difference between
the no-new-standards case and each standards case in terms of total
savings in operating costs versus total increases in installed costs.
DOE calculates operating cost savings over the lifetime of each product
shipped during the projection period.
As discussed in section IV.F.1 of this document, DOE developed
separate product price trends for electric and gas cooking products
based on a power-law fit of historical PPI data and cumulative
shipments. For the electric cooking products price trend, DOE used the
``Electric household ranges, ovens, surface cooking units and
equipment'' PPI for 1967-2021.\73\ For the gas cooking product price
trend, DOE used the ``Gas household ranges, ovens, surface cooking
units and equipment'' for 1981-2021.\74\ DOE applied the same trends to
project prices for each product class at each considered efficiency
level. By 2056, which is the end date of the projection period, the
average product price is projected to drop 17 percent relative to 2027
for electric cooking products, and 25 percent for gas cooking products.
DOE's projection of product prices is described in chapter 8 of the TSD
for this SNOPR.

---------------------------------------------------------------------------
To evaluate the effect of uncertainty regarding the price trend
estimates, DOE investigated the impact of different product price
projections on the consumer NPV for the considered TSLs for consumer
conventional cooking products. In addition to the default price trend,
DOE considered two product price sensitivity cases: (1) a high price
decline case based on a learning rate derived from subset of PPI data
for the period 1993-2021 for electric cooking products and the period
1981-2001 for gas cooking products (2) a low price decline case based
on a learning rate derived from a subset of PPI data from the period of
1967-1992 for electric cooking products and the period 2002-2021 for
gas cooking products. The derivation of these price trends and the
results of these sensitivity cases are described in appendix 10C of the
TSD for this SNOPR.
The energy cost savings are calculated using the estimated energy
savings in each year and the projected price of the appropriate form of
energy. To estimate energy prices in future years, DOE multiplied the
average regional energy prices by the projection of annual national-
average residential energy price changes in the Reference case from
AEO2022, which has an end year of 2050. To estimate price trends after
2050, DOE used a constant value derived from the average value between
2046 through 2050. As part of the NIA, DOE also analyzed scenarios that
used inputs from variants of the AEO2022 Reference case that have lower
and higher economic growth. Those cases have lower and higher energy
price trends compared to the Reference case. NIA results based on these
cases are presented in appendix 10C of the TSD for this SNOPR.
In calculating the NPV, DOE multiplies the net savings in future
years by a discount factor to determine their present value. For this
SNOPR, DOE estimated the NPV of consumer benefits using both a 3-
percent and a 7-percent real discount rate. DOE uses these discount
rates in accordance with guidance provided by the OMB to Federal
agencies on the development of regulatory analysis.\75\ The discount
rates for the determination of NPV are in contrast to the discount
rates used in the LCC analysis, which are designed to reflect a
consumer's perspective. The 7-percent real value is an estimate of the
average before-tax rate of return to private capital in the U.S.
economy. The 3-percent real value represents the ``social rate of time
preference,'' which is the rate at which society discounts future
consumption flows to their present value.

I. Consumer Subgroup Analysis
In analyzing the potential impact of new or amended energy
conservation standards on consumers, DOE evaluates the impact on
identifiable subgroups of consumers that may be disproportionately
affected by a new or amended national standard. The purpose of a
subgroup analysis is to determine the extent of any such
disproportional impacts. DOE evaluates impacts on particular subgroups
of consumers by analyzing the LCC impacts and PBP for those particular
consumers from alternative standard levels. For this SNOPR, DOE
analyzed the impacts of the considered standard levels on two
subgroups: (1) low-income households and (2) senior-only households.
The analysis used subsets of the RECS 2015 sample composed of
households that meet the criteria for the two subgroups. While the RECS
data offers further disaggregation of these consumer subgroups by owner
or renter status, DOE only examined the overall positive LCC savings to
these consumer subgroups and did not further
[[Page 6861]]
disaggregate the data. DOE used the LCC and PBP spreadsheet model to
estimate the impacts of the considered efficiency levels on these
subgroups. Chapter 11 in the TSD for this SNOPR describes the consumer
subgroup analysis.
DOE requests comment on whether additional consumer subgroups,
including any disaggregation of the subgroups analyzed in this SNOPR,
may be disproportionately affected by a new or amended national
standard and warrant additional analysis in the final rule.
J. Manufacturer Impact Analysis
1. Overview
DOE performed an MIA to estimate the financial impacts of new and
amended energy conservation standards on manufacturers of consumer
conventional cooking products and to estimate the potential impacts of
such standards on employment and manufacturing capacity. The MIA has
both quantitative and qualitative aspects and includes analyses of
projected industry cash flows, the INPV, investments in research and
development (``R&D'') and manufacturing capital, and domestic
manufacturing employment. Additionally, the MIA seeks to determine how
new and amended energy conservation standards might affect
manufacturing employment, capacity, and competition, as well as how
standards contribute to overall regulatory burden. Finally, the MIA
serves to identify any disproportionate impacts on manufacturer
subgroups, including small business manufacturers.
The quantitative part of the MIA primarily relies on the GRIM, an
industry cash flow model with inputs specific to this rulemaking. The
key GRIM inputs include data on the industry cost structure, unit
production costs, product shipments, manufacturer margins, and
investments in R&D and manufacturing capital required to produce
compliant products. The key GRIM outputs are the INPV, which is the sum
of industry annual cash flows over the analysis period, discounted
using the industry-weighted average cost of capital, and the impact to
domestic manufacturing employment. The model uses standard accounting
principles to estimate the impacts of more-stringent energy
conservation standards on a given industry by comparing changes in INPV
and domestic manufacturing employment between a no-new-standards case
and the various standards cases (i.e., TSLs). To capture the
uncertainty relating to manufacturer pricing strategies following new
and amended standards, the GRIM estimates a range of possible impacts
under different markup scenarios.
The qualitative part of the MIA addresses manufacturer
characteristics and market trends. Specifically, the MIA considers such
factors as a potential standard's impact on manufacturing capacity,
competition within the industry, the cumulative impact of other DOE and
non-DOE regulations, and the impacts on manufacturer subgroups. The
complete MIA is outlined in chapter 12 of the TSD for this SNOPR.
DOE conducted the MIA for this rulemaking in three phases. In Phase
1 of the MIA, DOE prepared a profile of the consumer conventional
cooking product manufacturing industry based on the market and
technology assessment, preliminary manufacturer interviews, and
publicly available information. This included a top-down analysis of
consumer conventional cooking product manufacturers that DOE used to
derive preliminary financial inputs for the GRIM (e.g., revenues;
materials, labor, overhead, and depreciation expenses; selling,
general, and administrative expenses (``SG&A''); and R&D expenses). DOE
also used public sources of information to further calibrate its
initial characterization of the consumer conventional cooking products
manufacturing industry, including company filings of form 10-K from the
SEC,\76\ corporate annual reports, the U.S. Census Bureau's Economic
Census,\77\ and reports from D&B Hoovers.\78\

\78\ Available at app.avention.com.
---------------------------------------------------------------------------
In Phase 2 of the MIA, DOE prepared a framework industry cash-flow
analysis to quantify the potential impacts of new and amended energy
conservation standards. The GRIM uses several factors to determine a
series of annual cash flows starting with the announcement of the
standard and extending over a 30-year period following the compliance
date of the standard. These factors include annual expected revenues,
costs of sales, SG&A and R&D expenses, taxes, and capital expenditures.
In general, energy conservation standards can affect manufacturer cash
flow in three distinct ways: (1) creating a need for increased
investment, (2) raising production costs per unit, and (3) altering
revenue due to higher per-unit prices and changes in sales volumes.
In addition, during Phase 2, DOE developed interview guides to
distribute to manufacturers of consumer conventional cooking products
in order to develop other key GRIM inputs, including product and
capital conversion costs, and to gather additional information on the
anticipated effects of energy conservation standards on revenues,
direct employment, capital assets, industry competitiveness, and
subgroup impacts.
In Phase 3 of the MIA, DOE conducted structured, detailed
interviews with representative manufacturers. During these interviews,
DOE discussed engineering, manufacturing, procurement, and financial
topics to validate assumptions used in the GRIM and to identify key
issues or concerns. As part of Phase 3, DOE also evaluated subgroups of
manufacturers that may be disproportionately impacted by new and
amended standards or that may not be accurately represented by the
average cost assumptions used to develop the industry cash flow
analysis. Such manufacturer subgroups may include small business
manufacturers, low-volume manufacturers (``LVMs''), niche players, and/
or manufacturers exhibiting a cost structure that largely differs from
the industry average. DOE identified two manufacturer subgroups for a
separate impact analysis: commercial-style manufacturers and small
business manufacturers. The commercial-style manufacturer subgroup is
discussed in section V.B.2.d of this document. The small business
subgroup is discussed in section VI.B of this document.
2. Government Regulatory Impact Model and Key Inputs
DOE uses the GRIM to quantify the changes in cash flow due to new
and amended standards that result in a higher or lower industry value.
The GRIM uses a standard, annual discounted cash-flow analysis that
incorporates manufacturer costs, markups, shipments, and industry
financial information as inputs. The GRIM models changes in costs,
distribution of shipments, investments, and manufacturer margins that
could result from new and amended energy conservation standards. The
GRIM spreadsheet uses the inputs to arrive at a series of annual cash
flows, beginning in 2022 (the reference year of the analysis) and
continuing to 2056. DOE calculated INPVs by summing the stream of
annual discounted cash flows during this period. For manufacturers of
consumer conventional cooking
[[Page 6862]]
products, DOE used a real discount rate of 9.1 percent, which was
derived from industry financials and then modified according to
feedback received during manufacturer interviews.
DOE requests comment on the use of 9.1 percent as an appropriate
real discount rate for consumer conventional cooking product
manufacturers.
The GRIM calculates cash flows using standard accounting principles
and compares changes in INPV between the no-new-standards case and each
standards case. The difference in INPV between the no-new-standards
case and a standards case represents the financial impact of the new
and amended energy conservation standards on manufacturers. As
discussed previously, DOE developed critical GRIM inputs using a number
of sources, including publicly available data, results of the
engineering analysis, and information gathered from industry
stakeholders during the course of manufacturer interviews. The GRIM
results are presented in section V.B.2 of this document. Additional
details about the GRIM, the discount rate, and other financial
parameters can be found in chapter 12 of the TSD for this SNOPR.
a. Manufacturer Production Costs
Manufacturing more efficient products is typically more expensive
than manufacturing baseline products due to the use of more complex
components, which are typically more costly than baseline components.
The changes in the MPCs of the covered products can affect the
revenues, manufacturer margins, and cash flow of the industry.
In the MIA, DOE used the MPCs calculated in the engineering
analysis, as described in section IV.C of this document and further
detailed in chapter 5 of the TSD for this SNOPR. For this SNOPR
analysis, DOE used a design-option approach supported by testing,
supplemented by reverse engineering (physical teardowns and testing of
existing products in the market) to identify the incremental cost and
efficiency improvement associated with each design option or design
option combination. DOE used these updated MPCs from the engineering
analysis in this MIA.
b. Shipments Projections
The GRIM estimates manufacturer revenues based on total unit
shipment projections and the distribution of those shipments by
efficiency level. Changes in sales volumes and efficiency mix over time
can significantly affect manufacturer finances. For this analysis, the
GRIM uses the NIA's annual shipment projections derived from the
shipments analysis from 2022 (the reference year) to 2056 (the end year
of the analysis period). See chapter 9 of the TSD for this SNOPR for
additional details.
c. Product and Capital Conversion Costs
New or amended energy conservation standards could cause
manufacturers to incur conversion costs to bring their production
facilities and product designs into compliance. DOE evaluated the level
of conversion-related expenditures that would be needed to comply with
each considered efficiency level in each product class. For the MIA,
DOE classified these conversion costs into two major groups: (1)
product conversion costs; and (2) capital conversion costs. Product
conversion costs are investments in research, development, testing,
marketing, and other non-capitalized costs necessary to make product
designs comply with new and amended energy conservation standards.
Capital conversion costs are investments in property, plant, and
equipment necessary to adapt or change existing production facilities
such that new compliant product designs can be fabricated and
assembled.
To evaluate the level of capital conversion costs manufacturers
would likely incur to comply with new and amended energy conservation
standards, DOE estimated the capital investments that a major and minor
consumer conventional cooking product manufacturer would be required to
make to be able to manufacture compliant products at each efficiency
levels for each product class. DOE then scaled these cost investment
estimates by the number of major and minor consumer conventional
cooking product manufacturers to arrive at the industry conversion cost
estimates.
To evaluate the level of product conversion costs manufacturers
would likely incur to comply with amended energy conservation
standards, DOE estimated the number of consumer conventional cooking
product models currently on the market, the efficiency distribution of
those models on the market, the estimated testing cost to test to the
DOE test procedure (for cooking tops only), and the estimated per model
R&D costs to redesign a non-compliant model into a compliant model for
each analyzed efficiency level.
DOE used DOE's Compliance Certification Database (``CCD''),\79\
California Energy Commission's (``CEC's'') MAEDBS database,\80\ and
Canada's Natural Resources Canada database \81\ to identify consumer
conventional cooking product models covered by this rulemaking. DOE
used the efficiency distribution of the shipments analysis to estimate
the model efficiency distribution. DOE increased the cost estimates
from the August 2022 TP Final Rule \82\ based on manufacturer feedback
and used these higher per unit testing costs to estimate the per model
testing costs for cooking tops. Lastly, DOE estimated separate per
model R&D costs for each product class at each efficiency level based
on manufacturer interviews and inputs from the engineering analysis.
DOE then combined the per model testing and R&D costs with the number
of models that would need to be tested and redesigned to estimate the
industry product conversion costs.

In general, DOE assumes all conversion-related investments occur
between the year of publication of the final rule and the year by which
manufacturers must comply with the new and amended standards. The
conversion cost figures used in the GRIM can be found in section V.B.2
of this document. For additional information on the estimated capital
and product conversion costs, see chapter 12 of the TSD for this SNOPR.
d. Markup Scenarios
MSPs include direct manufacturing production costs (i.e., labor,
materials, and overhead estimated in DOE's MPCs) and all non-production
costs (i.e., SG&A, R&D, and interest), along with profit. To calculate
the MSPs in the GRIM, DOE applied manufacturer margins to the MPCs
estimated in the engineering analysis for each product class and
efficiency level. Modifying these margins in the standards case yields
different sets of impacts on manufacturers. For the MIA, DOE modeled
two standards-case scenarios to represent uncertainty regarding the
potential impacts on prices and profitability for manufacturers
following the implementation of new and amended energy conservation
standards: (1) a preservation of gross margin scenario; and (2) a
preservation of operating profit scenario. These
[[Page 6863]]
scenarios lead to different margins that, when applied to the MPCs,
result in varying revenue and cash flow impacts on manufacturers.
Under the preservation of gross margin scenario, DOE applied the
same ``gross margin percentage'' across all efficiency levels in the
standards-cases that is used in the no-new-standards case. This
scenario assumes that manufacturers would be able to maintain the same
margin of 17 percent, that is used in the no-new-standards case, in all
standards cases, even as the MPCs increase due to energy conservation
standards.\83\ This margin is the same margin that was used in the
December 2020 NOPD. This scenario represents the upper bound to
industry profitability under new and amended energy conservation
standards.
---------------------------------------------------------------------------
\83\ The gross margin percentage of 17 percent is based on a
manufacturer markup of 1.20.
---------------------------------------------------------------------------
Under the preservation of operating profit scenario, DOE modeled a
situation in which manufacturers are not able to increase per-unit
operating profit in proportion to increases in MPCs. Under this
scenario, as the MPCs increase, manufacturers reduce their margins (on
a percentage basis) to a level that maintains the no-new-standards
operating profit (in absolute dollars). The implicit assumption behind
this scenario is that the industry can only maintain its operating
profit in absolute dollars after compliance with new and amended
standards. Therefore, operating profit in percentage terms is reduced
between the no-new-standards case and the analyzed standards cases. DOE
adjusted the margins in the GRIM at each TSL to yield approximately the
same earnings before interest and taxes in the standards case in the
year after the compliance date of the new and amended standards as in
the no-new-standards case. This scenario represents the lower bound to
industry profitability under new and amended energy conservation
standards.
A comparison of industry financial impacts under the two scenarios
is presented in section V.B.2.a of this document.
K. Emissions Analysis
The emissions analysis consists of two components. The first
component estimates the effect of potential energy conservation
standards on power sector and site (where applicable) combustion
emissions of CO2, NOX, SO2, and Hg.
The second component estimates the impacts of potential standards on
emissions of two additional greenhouse gases, CH4 and
N2O, as well as the reductions to emissions of other gases
due to ``upstream'' activities in the fuel production chain. These
upstream activities comprise extraction, processing, and transporting
fuels to the site of combustion.
The analysis of electric power sector emissions of CO2,
NOX, SO2, and Hg uses emissions factors intended
to represent the marginal impacts of the change in electricity
consumption associated with amended or new standards. The methodology
is based on results published for the AEO, including a set of side
cases that implement a variety of efficiency-related policies. The
methodology is described in appendix 13A in the TSD for this SNOPR. The
analysis presented in this notice uses projections from AEO2022. Power
sector emissions of CH4 and N2O from fuel
combustion are estimated using Emission Factors for Greenhouse Gas
Inventories published by the Environmental Protection Agency
(``EPA'').\84\

The on-site operation of consumer conventional cooking products
requires combustion of fossil fuels and results in emissions of
CO2, NOX, SO2, CH4, and
N2O, where these products are used. Site emissions of these
gases were estimated using Emission Factors for Greenhouse Gas
Inventories and, for NOX and SO2 emissions
intensity factors from an EPA publication.\85\

---------------------------------------------------------------------------
A 2022 study by Stanford University (``Stanford Study''), which
measured methane emissions in 53 California homes, suggests that gas
ranges (including the gas cooking top and gas oven portions) contribute
methane emissions that were estimated to be 0.8 to 1.3 percent of gas
consumption for active (cooking) mode due to incomplete combustion and
post-meter leakage during active, standby, and off modes.\86\ Further,
a significant majority (three-quarters) of these emissions take place
during standby mode due to leakage. In active mode, the Stanford Study
noted that such emissions occurred both during steady-state operation
and during burner ignition/extinction. Gas cooking tops with standing
pilot lights released on average over 10 times the methane during each
ignition event than those with electronic spark ignition. Regarding
standby mode, the Stanford Study found that 48 out of the 53 gas ranges
measured, along with their associated nearby piping, leaked some
methane continuously. The Stanford Study estimated that, over a 20-year
analysis period, the annual methane emissions from all gas-fired
consumer conventional cooking products in U.S. homes have a climate
impact comparable to the annual CO2 emissions from 500,000
automobiles. Additionally, increased methane emissions contribute to
the formation of surface level ozone which has been linked to negative
health outcomes.

---------------------------------------------------------------------------
Studies from the emerging field of indoor air quality have measured
emissions of additional pollutants associated with gas cooking products
not quantified in this SNOPR analysis that may potentially contribute
to negative health impacts, especially in areas with inadequate
ventilation.87 88 Such in-home emissions may be associated
with a variety of serious respiratory and cardiovascular conditions and
other health risks. Reduced in-home gas combustion may deliver
additional health benefits to consumers and their families by reducing
exposure to various pollutants. The level of health benefits may also
depend on the degree to which a household uses or has access to proper
ventilation. Although the benefits in reductions of these pollutants
are not quantified in this SNOPR analysis, reductions of on-site
emissions provide health benefits to sensitive populations such as
children, elderly, and household members with respiratory
conditions.\89\ These subgroups are likely to experience more acutely
health effects that are caused or exacerbated by the on-site emissions.
DOE acknowledges the potential heath impact of these emissions, but
notes the uncertainty in quantifying their impact in this emerging area
of study.

DOE notes that the current energy conservation standards for
consumer conventional cooking products established in the April 2009
Final Rule prohibit constant burning pilots for all gas cooking
products (i.e., gas cooking
[[Page 6864]]
products both with or without an electrical supply cord) manufactured
on and after April 9, 2012. 10 CFR 430.32(j)(1)-(2). In this SNOPR, DOE
analyzed a design option and corresponding efficiency levels for gas
cooking tops, optimized burner/improved grates, that are associated
with improvements in combustion characteristics. In general, higher
efficiency burner systems correlate with more complete combustion and
thus more efficient conversion of the energy content in the gas to
thermal energy.
DOE seeks comment on any health impacts to consumers, environmental
impacts, or general public health and welfare impacts (including the
distribution of such impacts across sensitive populations) of its
proposals in this SNOPR on on-site emissions from gas cooking products
of methane, carbon dioxide, particulate matter, nitrogen dioxide, or
other hazardous air emissions. DOE also seeks comment on whether
manufacturers are instituting design approaches, control strategies, or
other measures to mitigate methane or other emissions from incomplete
combustion and leakage.
FFC upstream emissions, which include emissions from fuel
combustion during extraction, processing, and transportation of fuels,
and ``fugitive'' emissions (direct leakage to the atmosphere) of
CH4 and CO2, are estimated based on the
methodology described in chapter 15 of the TSD for this SNOPR.
The emissions intensity factors are expressed in terms of physical
units per MWh or MMBtu of site energy savings. For power sector
emissions, specific emissions intensity factors are calculated by
sector and end use. Total emissions reductions are estimated using the
energy savings calculated in the national impact analysis.
1. Air Quality Regulations Incorporated in DOE's Analysis
DOE's no-new-standards case for the electric power sector reflects
the AEO, which incorporates the projected impacts of existing air
quality regulations on emissions. AEO2022 generally represents current
legislation and environmental regulations, including recent government
actions, that were in place at the time of preparation of AEO2022,
including the emissions control programs discussed in the following
paragraphs.\90\
---------------------------------------------------------------------------
\90\ For further information, see the Assumptions to AEO2022
report that sets forth the major assumptions used to generate the
projections in the Annual Energy Outlook. Available at www.eia.gov/outlooks/aeo/assumptions/ (last accessed June 28, 2022).
---------------------------------------------------------------------------
SO2 emissions from affected electric generating units
(``EGUs'') are subject to nationwide and regional emissions cap-and-
trade programs. Title IV of the Clean Air Act sets an annual emissions
cap on SO2 for affected EGUs in the 48 contiguous States and
the District of Columbia (``DC''). (42 U.S.C. 7651 et seq.)
SO2 emissions from numerous States in the eastern half of
the United States are also limited under the Cross-State Air Pollution
Rule (``CSAPR''). 76 FR 48208 (Aug. 8, 2011). CSAPR requires these
States to reduce certain emissions, including annual SO2
emissions, and went into effect as of January 1, 2015.\91\ AEO2022
incorporates implementation of CSAPR, including the update to the CSAPR
ozone season program emission budgets and target dates issued in 2016.
81 FR 74504 (Oct. 26, 2016). Compliance with CSAPR is flexible among
EGUs and is enforced through the use of tradable emissions allowances.
Under existing EPA regulations, any excess SO2 emissions
allowances resulting from the lower electricity demand caused by the
adoption of an efficiency standard could be used to permit offsetting
increases in SO2 emissions by another regulated EGU.
---------------------------------------------------------------------------
\91\ CSAPR requires states to address annual emissions of
SO2 and NOX, precursors to the formation of
fine particulate matter (PM2.5) pollution, in order to
address the interstate transport of pollution with respect to the
1997 and 2006 PM2.5 National Ambient Air Quality
Standards (``NAAQS''). CSAPR also requires certain states to address
the ozone season (May-September) emissions of NOX, a
precursor to the formation of ozone pollution, in order to address
the interstate transport of ozone pollution with respect to the 1997
ozone NAAQS. 76 FR 48208 (Aug. 8, 2011). EPA subsequently issued a
supplemental rule that included an additional five states in the
CSAPR ozone season program. 76 FR 80760 (Dec. 27, 2011)
(Supplemental Rule).
---------------------------------------------------------------------------
However, beginning in 2016, SO2 emissions began to fall
as a result of the Mercury and Air Toxics Standards (``MATS'') for
power plants. 77 FR 9304 (Feb. 16, 2012). In the MATS final rule, EPA
established a standard for hydrogen chloride as a surrogate for acid
gas hazardous air pollutants (``HAP''), and also established a standard
for SO2 (a non-HAP acid gas) as an alternative equivalent
surrogate standard for acid gas HAP. The same controls are used to
reduce HAP and non-HAP acid gas; thus, SO2 emissions are
being reduced as a result of the control technologies installed on
coal-fired power plants to comply with the MATS requirements for acid
gas. In order to continue operating, coal power plants must have either
flue gas desulfurization or dry sorbent injection systems installed.
Both technologies, which are used to reduce acid gas emissions, also
reduce SO2 emissions. Because of the emissions reductions
under the MATS, it is unlikely that excess SO2 emissions
allowances resulting from the lower electricity demand would be needed
or used to permit offsetting increases in SO2 emissions by
another regulated EGU. Therefore, energy conservation standards that
decrease electricity generation would generally reduce SO2
emissions. DOE estimated SO2 emissions reduction using
emissions factors based on AEO2022.
CSAPR also established limits on NOX emissions for
numerous States in the eastern half of the United States. Energy
conservation standards would have little effect on NOX
emissions in those States covered by CSAPR emissions limits if excess
NOX emissions allowances resulting from the lower
electricity demand could be used to permit offsetting increases in
NOX emissions from other EGUs. In such case, NOX
emissions would remain near the limit even if electricity generation
goes down. A different case could possibly result, depending on the
configuration of the power sector in the different regions and the need
for allowances, such that NOX emissions might not remain at
the limit in the case of lower electricity demand. In this case, energy
conservation standards might reduce NOX emissions in covered
States. Despite this possibility, DOE has chosen to be conservative in
its analysis and has maintained the assumption that standards will not
reduce NOX emissions in States covered by CSAPR. Energy
conservation standards would be expected to reduce NOX
emissions in the States not covered by CSAPR. DOE used AEO2022 data to
derive NOX emissions factors for the group of States not
covered by CSAPR.
The MATS limit mercury emissions from power plants, but they do not
include emissions caps and, as such, DOE's energy conservation
standards would be expected to slightly reduce Hg emissions. DOE
estimated mercury emissions reduction using emissions factors based on
AEO2022, which incorporates the MATS.
L. Monetizing Emissions Impacts
As part of the development of this proposed rule, for the purpose
of complying with the requirements of Executive Order 12866, DOE
considered the estimated monetary benefits from the reduced emissions
of CO2, CH4, N2O, NOX, and
SO2 that are expected to result from each of the TSLs
considered. In order to make this calculation analogous to the
calculation of the NPV of consumer benefit, DOE considered the reduced
emissions expected to
[[Page 6865]]
result over the lifetime of products shipped in the projection period
for each TSL. This section summarizes the basis for the values used for
monetizing the emissions benefits and presents the values considered in
this SNOPR.
On March 16, 2022, the Fifth Circuit Court of Appeals (No. 22-
30087) granted the Federal government's emergency motion for stay
pending appeal of the February 11, 2022, preliminary injunction issued
in Louisiana v. Biden, No. 21-cv-1074-JDC-KK (W.D. La.). As a result of
the Fifth Circuit's order, the preliminary injunction is no longer in
effect, pending resolution of the Federal government's appeal of that
injunction or a further court order. Among other things, the
preliminary injunction enjoined the defendants in that case from
``adopting, employing, treating as binding, or relying upon'' the
interim estimates of the social cost of greenhouse gases--which were
issued by the Interagency Working Group on the Social Cost of
Greenhouse Gases on February 26, 2021--to monetize the benefits of
reducing greenhouse gas emissions. As reflected in this rule, DOE has
reverted to its approach prior to the injunction and presents monetized
benefits where appropriate and permissible under law. However, DOE
notes it would reach the same conclusion presented in this proposed
rulemaking that the proposed standards are economically justified no
matter what value is ascribed to climate benefits. DOE requests comment
on how to address the climate benefits and other non-monetized effects
of the proposal.
1. Monetization of Greenhouse Gas Emissions
DOE estimates the monetized benefits of the reductions in emissions
of CO2, CH4, and N2O by using a
measure of the social cost (``SC'') of each pollutant (e.g., SC-
CO2). These estimates represent the monetary value of the
net harm to society associated with a marginal increase in emissions of
these pollutants in a given year, or the benefit of avoiding that
increase. These estimates are intended to include (but are not limited
to) climate-change-related changes in net agricultural productivity,
human health, property damages from increased flood risk, disruption of
energy systems, risk of conflict, environmental migration, and the
value of ecosystem services.
DOE exercises its own judgment in presenting monetized climate
benefits as recommended by applicable Executive orders and DOE would
reach the same conclusion presented in this proposed rulemaking in the
absence of the social cost of greenhouse gases. That is, the social
costs of greenhouse gases, whether measured using the February 2021
interim estimates presented by the Interagency Working Group on the
Social Cost of Greenhouse Gases or by another means, did not affect the
rule ultimately proposed by DOE.
DOE estimated the global social benefits of CO2,
CH4, and N2O reductions (i.e., SC-GHGs) using the
estimates presented in the Technical Support Document: Social Cost of
Carbon, Methane, and Nitrous Oxide Interim Estimates under Executive
Order 13990, published in February 2021 by the IWG. The SC-GHGs is the
monetary value of the net harm to society associated with a marginal
increase in emissions in a given year, or the benefit of avoiding that
increase. In principle, SC-GHGs includes the value of all climate
change impacts, including (but not limited to) changes in net
agricultural productivity, human health effects, property damage from
increased flood risk and natural disasters, disruption of energy
systems, risk of conflict, environmental migration, and the value of
ecosystem services. The SC-GHGs therefore, reflects the societal value
of reducing emissions of the gas in question by one metric ton. The SC-
GHGs is the theoretically appropriate value to use in conducting
benefit-cost analyses of policies that affect CO2,
N2O and CH4 emissions. As a member of the IWG
involved in the development of the February 2021 SC-GHG TSD, DOE agrees
that the interim SC-GHG estimates represent the most appropriate
estimate of the SC-GHG until revised estimates have been developed
reflecting the latest, peer-reviewed science.
The SC-GHGs estimates presented here were developed over many
years, using a transparent process, peer-reviewed methodologies, the
best science available at the time of that process, and with input from
the public. Specifically, in 2009, the IWG, that included the DOE and
other executive branch agencies and offices, was established to ensure
that agencies were using the best available science and to promote
consistency in the social cost of carbon (i.e., SC-CO2)
values used across agencies. The IWG published SC-CO2
estimates in 2010 that were developed from an ensemble of three widely
cited integrated assessment models (``IAMs'') that estimate global
climate damages using highly aggregated representations of climate
processes and the global economy combined into a single modeling
framework. The three IAMs were run using a common set of input
assumptions in each model for future population, economic, and
CO2 emissions growth, as well as equilibrium climate
sensitivity--a measure of the globally averaged temperature response to
increased atmospheric CO2 concentrations. These estimates
were updated in 2013 based on new versions of each IAM. In August 2016,
the IWG published estimates of the social cost of methane (i.e., SC-
CH4) and nitrous oxide (i.e., SC-N2O) using
methodologies that are consistent with the methodology underlying the
SC-CO2 estimates. The modeling approach that extends the IWG
SC-CO2 methodology to non-CO2 GHGs has undergone
multiple stages of peer review. The SC-CH4 and SC-
N2O estimates were developed by Marten et al.\92\ and
underwent a standard double-blind peer review process prior to journal
publication. In 2015, as part of the response to public comments
received to a 2013 solicitation for comments on the SC-CO2
estimates, the IWG announced a National Academies of Sciences,
Engineering, and Medicine review of the SC-CO2 estimates to
offer advice on how to approach future updates to ensure that the
estimates continue to reflect the best available science and
methodologies. In January 2017, the National Academies released their
final report, ``Valuing Climate Damages: Updating Estimation of the
Social Cost of Carbon Dioxide,'' and recommended specific criteria for
future updates to the SC-CO2 estimates, a modeling framework
to satisfy the specified criteria, and both near-term updates and
longer-term research needs pertaining to various components of the
estimation process (National Academies, 2017).\93\ Shortly thereafter,
in March 2017, President Trump issued Executive Order 13783, which
disbanded the IWG, withdrew the previous TSDs, and directed agencies to
ensure SC-CO2 estimates used in regulatory analyses are
consistent with the guidance contained in OMB's Circular A-4,
``including with respect to the consideration of domestic versus
international impacts and the consideration of appropriate discount
rates'' (E.O. 13783, Section 5(c)). Benefit-cost analyses following
E.O. 13783 used SC-GHG estimates that attempted to focus on the U.S.-
specific
[[Page 6866]]
share of climate change damages as estimated by the models and were
calculated using two discount rates recommended by Circular A-4, 3
percent and 7 percent. All other methodological decisions and model
versions used in SC-GHG calculations remained the same as those used by
the IWG in 2010 and 2013, respectively.

On January 20, 2021, President Biden issued Executive Order 13990,
which re-established the IWG and directed it to ensure that the U.S.
Government's estimates of the social cost of carbon and other
greenhouse gases reflect the best available science and the
recommendations of the National Academies (2017). The IWG was tasked
with first reviewing the SC-GHG estimates currently used in Federal
analyses and publishing interim estimates within 30 days of the E.O.
that reflect the full impact of GHG emissions, including by taking
global damages into account. The interim SC-GHG estimates published in
February 2021 are used here to estimate the climate benefits for this
proposed rulemaking. The E.O. instructs the IWG to undertake a fuller
update of the SC-GHG estimates by January 2022 that takes into
consideration the advice of the National Academies (2017) and other
recent scientific literature. The February 2021 SC-GHG TSD provides a
complete discussion of the IWG's initial review conducted under E.O.
13990. In particular, the IWG found that the SC-GHG estimates used
under E.O. 13783 fail to reflect the full impact of GHG emissions in
multiple ways.
First, the IWG found that the SC-GHG estimates used under E.O.
13783 fail to fully capture many climate impacts that affect the
welfare of U.S. citizens and residents, and those impacts are better
reflected by global measures of the SC-GHG. Examples of omitted effects
from the E.O. 13783 estimates include direct effects on U.S. citizens,
assets, and investments located abroad, supply chains, U.S. military
assets and interests abroad, and tourism, and spillover pathways such
as economic and political destabilization and global migration that can
lead to adverse impacts on U.S. national security, public health, and
humanitarian concerns. In addition, assessing the benefits of U.S. GHG
mitigation activities requires consideration of how those actions may
affect mitigation activities by other countries, as those international
mitigation actions will provide a benefit to U.S. citizens and
residents by mitigating climate impacts that affect U.S. citizens and
residents. A wide range of scientific and economic experts have
emphasized the issue of reciprocity as support for considering global
damages of GHG emissions. If the United States does not consider
impacts on other countries, it is difficult to convince other countries
to consider the impacts of their emissions on the United States. The
only way to achieve an efficient allocation of resources for emissions
reduction on a global basis--and so benefit the U.S. and its citizens--
is for all countries to base their policies on global estimates of
damages. As a member of the IWG involved in the development of the
February 2021 SC-GHG TSD, DOE agrees with this assessment and,
therefore, in this proposed rule DOE centers attention on a global
measure of SC-GHG. This approach is the same as that taken in DOE
regulatory analyses from 2012 through 2016. A robust estimate of
climate damages that accrue only to U.S. citizens and residents does
not currently exist in the literature. As explained in the February
2021 TSD, existing estimates are both incomplete and an underestimate
of total damages that accrue to the citizens and residents of the U.S.
because they do not fully capture the regional interactions and
spillovers discussed above, nor do they include all of the important
physical, ecological, and economic impacts of climate change recognized
in the climate change literature. As noted in the February 2021 SC-GHG
TSD, the IWG will continue to review developments in the literature,
including more robust methodologies for estimating a U.S.-specific SC-
GHG value, and explore ways to better inform the public of the full
range of carbon impacts. As a member of the IWG, DOE will continue to
follow developments in the literature pertaining to this issue.
Second, the IWG found that the use of the social rate of return on
capital (7 percent under current OMB Circular A-4 guidance) to discount
the future benefits of reducing GHG emissions inappropriately
underestimates the impacts of climate change for the purposes of
estimating the SC-GHG. Consistent with the findings of the National
Academies (2017) and the economic literature, the IWG continued to
conclude that the consumption rate of interest is the theoretically
appropriate discount rate in an intergenerational context,\94\ and
recommended that discount rate uncertainty and relevant aspects of
intergenerational ethical considerations be accounted for in selecting
future discount rates.

---------------------------------------------------------------------------
Furthermore, the damage estimates developed for use in the SC-GHG
are estimated in consumption-equivalent terms, and so an application of
OMB Circular A-4's guidance for regulatory analysis would then use the
consumption discount rate to calculate the SC-GHG. DOE agrees with this
assessment and will continue to follow developments in the literature
pertaining to this issue. DOE also notes that while OMB Circular A-4,
as published in 2003, recommends using 3- and 7-percent discount rates
as ``default'' values, Circular A-4 also reminds agencies that
``different regulations may call for different emphases in the
analysis, depending on the nature and complexity of the regulatory
issues and the sensitivity of the benefit and cost estimates to the key
assumptions.'' On discounting, Circular A-4 recognizes that ``special
ethical considerations arise when comparing benefits and costs across
generations,'' and Circular A-4 acknowledges that analyses may
appropriately ``discount future costs and consumption benefits [. . .]
at a lower rate than for intragenerational analysis.'' In the 2015
Response to Comments on the Social Cost of Carbon for Regulatory Impact
Analysis, OMB, DOE, and the other IWG members recognized that
``Circular A-4 is a living document'' and ``the use of 7 percent is not
considered appropriate for intergenerational discounting. There is wide
support for this view in the academic literature, and it is recognized
in Circular A-4 itself.'' Thus, DOE concludes that a 7 percent discount
rate is not appropriate to apply to value the social cost of greenhouse
gases in the analysis presented in this analysis.
To calculate the present and annualized values of climate benefits,
[[Page 6867]]
DOE uses the same discount rate as the rate used to discount the value
of damages from future GHG emissions, for internal consistency. That
approach to discounting follows the same approach that the February
2021 TSD recommends ``to ensure internal consistency--i.e., future
damages from climate change using the SC-GHG at 2.5 percent should be
discounted to the base year of the analysis using the same 2.5 percent
rate.'' DOE has also consulted the National Academies' 2017
recommendations on how SC-GHG estimates can ``be combined in RIAs
[regulatory impact analyses] with other cost and benefits estimates
that may use different discount rates.'' The National Academies
reviewed ``several options,'' including ``presenting all discount rate
combinations of other costs and benefits with [SC-GHG] estimates.''
As a member of the IWG involved in the development of the February
2021 SC-GHG TSD, DOE agrees with this assessment and will continue to
follow developments in the literature pertaining to this issue. While
the IWG works to assess how best to incorporate the latest, peer
reviewed science to develop an updated set of SC-GHG estimates, it set
the interim estimates to be the most recent estimates developed by the
IWG prior to the group being disbanded in 2017. The estimates rely on
the same models and harmonized inputs and are calculated using a range
of discount rates. As explained in the February 2021 SC-GHG TSD, the
IWG has recommended that agencies revert to the same set of four values
drawn from the SC-GHG distributions based on three discount rates as
were used in regulatory analyses between 2010 and 2016 and subject to
public comment. For each discount rate, the IWG combined the
distributions across models and socioeconomic emissions scenarios
(applying equal weight to each) and then selected a set of four values
recommended for use in benefit-cost analyses: an average value
resulting from the model runs for each of three discount rates (2.5
percent, 3 percent, and 5 percent), plus a fourth value, selected as
the 95th percentile of estimates based on a 3 percent discount rate.
The fourth value was included to provide information on potentially
higher-than-expected economic impacts from climate change. As explained
in the February 2021 SC-GHG TSD, and DOE agrees, this update reflects
the immediate need to have an operational SC-GHG for use in regulatory
benefit-cost analyses and other applications that was developed using a
transparent process, peer-reviewed methodologies, and the science
available at the time of that process. Those estimates were subject to
public comment in the context of dozens of proposed rulemakings as well
as in a dedicated public comment period in 2013.
There are a number of limitations and uncertainties associated with
the SC-GHG estimates. First, the current scientific and economic
understanding of discounting approaches suggests discount rates
appropriate for intergenerational analysis in the context of climate
change are likely to be less than 3 percent, near 2 percent or
lower.\95\ Second, the IAMs used to produce these interim estimates do
not include all of the important physical, ecological, and economic
impacts of climate change recognized in the climate change literature
and the science underlying their ``damage functions''--i.e., the core
parts of the IAMs that map global mean temperature changes and other
physical impacts of climate change into economic (both market and
nonmarket) damages--lags behind the most recent research. For example,
limitations include the incomplete treatment of catastrophic and non-
catastrophic impacts in the integrated assessment models, their
incomplete treatment of adaptation and technological change, the
incomplete way in which inter-regional and intersectoral linkages are
modeled, uncertainty in the extrapolation of damages to high
temperatures, and inadequate representation of the relationship between
the discount rate and uncertainty in economic growth over long time
horizons. Likewise, the socioeconomic and emissions scenarios used as
inputs to the models do not reflect new information from the last
decade of scenario generation or the full range of projections. The
modeling limitations do not all work in the same direction in terms of
their influence on the SC-CO2 estimates. However, as
discussed in the February 2021 TSD, the IWG has recommended that, taken
together, the limitations suggest that the interim SC-GHG estimates
used in this SNOPR likely underestimate the damages from GHG emissions.
DOE concurs with this assessment.

DOE's derivations of the SC-GHG values (i.e., SC-CO2,
SC-N2O, and SC-CH4) used for this SNOPR are
discussed in the following sections, and the results of DOE's analyses
estimating the benefits of the reductions in emissions of these GHGs
are presented in section V.B.6 of this document.
a. Social Cost of Carbon
The SC-CO2 values used for this SNOPR were based on the
values presented for the IWG's February 2021 TSD. Table IV.34 shows the
updated sets of SC-CO2 estimates from the IWG's February
2021 TSD in 5-year increments from 2020 to 2050. The full set of annual
values that DOE used is presented in appendix 14A of the TSD for this
SNOPR. For purposes of capturing the uncertainties involved in
regulatory impact analysis, DOE has determined it is appropriate
include all four sets of SC-CO2 values, as recommended by
the IWG.\96\
---------------------------------------------------------------------------
\96\ For example, the February 2021 TSD discusses how the
understanding of discounting approaches suggests that discount rates
appropriate for intergenerational analysis in the context of climate
change may be lower than 3 percent.

----------------------------------------------------------------------------------------------------------------
For 2051 to 2070, DOE used SC-CO2 estimates published by
EPA, adjusted to 2020$.\97\ These estimates are based on methods,
assumptions, and parameters identical to the 2020-2050 estimates
published by the IWG. DOE expects additional climate benefits to accrue
for any longer-life consumer conventional cooking products after 2070,
but a lack of available SC-CO2 estimates for emissions years
beyond 2070 prevents DOE from monetizing these potential benefits in
this analysis. DOE notes that the SC-CO2 monetization
results presented in this SNOPR are a conservative estimate and that
the inclusion of emissions after 2070 would slightly increase estimated
benefits.

---------------------------------------------------------------------------
DOE multiplied the CO2 emissions reduction estimated for
each year by the SC-CO2 value for that year in each of the
four cases. DOE adjusted the values to 2021$ using the implicit price
deflator for gross domestic product (``GDP'') from the Bureau of
Economic Analysis. To calculate a present value of the stream of
monetary values, DOE discounted the values in each of the four cases
using the specific discount rate that had been used to obtain the SC-
CO2 values in each case.
b. Social Cost of Methane and Nitrous Oxide
The SC-CH4 and SC-N2O values used for this
SNOPR were based on the values developed for the February 2021 TSD.
Table IV.35 shows the updated sets of SC-CH4 and SC-
N2O estimates from the latest interagency update in 5-year
increments from 2020 to 2050. The full set of annual values used is
presented in appendix 14A of the TSD for this SNOPR. To capture the
uncertainties involved in regulatory impact analysis, DOE has
determined it is appropriate to include all four sets of SC-
CH4 and SC-N2O values, as recommended by the IWG.
DOE derived values after 2050 using the approach described above for
the SC-CO2.

--------------------------------------------------------------------------------------------------------------------------------------------------------
DOE multiplied the CH4 and N2O emissions
reduction estimated for each year by the SC-CH4 and SC-
N2O estimates for that year in each of the cases. DOE
adjusted the values to 2021$ using the implicit price deflator for GDP
from the Bureau of Economic Analysis. To calculate a present value of
the stream of monetary values, DOE discounted the values in each of the
cases using the specific discount rate that had been used to obtain the
SC-CH4 and SC-N2O estimates in each case.
2. Monetization of Other Emissions Impacts
For the SNOPR, DOE estimated the monetized value of NOX
and SO2 emissions reductions from electricity generation
using the latest benefit per ton estimates for that sector from the
EPA's Benefits Mapping and Analysis Program.\98\ DOE used EPA's values
for PM2.5-related benefits associated with NOX
and SO2 and for ozone-related benefits associated with
NOX for 2025, 2030, and 2040, calculated with discount rates
of 3 percent and 7 percent. DOE used linear interpolation to define
values for the years not given in the 2025 to 2040 period; for years
beyond 2040 the values are held constant. DOE derived values specific
to the sector for consumer conventional cooking products using a method
described in appendix 14B of the TSD for this SNOPR.
---------------------------------------------------------------------------
\98\ Estimating the Benefit per Ton of Reducing PM2.5 Precursors
from 21 Sectors. Available at www.epa.gov/benmap/estimating-benefit-ton-reducing-pm25-precursors-21-sectors.
---------------------------------------------------------------------------
DOE also estimated the monetized value of NOX and
SO2 emissions reductions from site use of natural gas in
consumer conventional cooking products using benefit-per-ton estimates
from the EPA's Benefits Mapping and Analysis Program. Although none of
the sectors covered by EPA refers
[[Page 6869]]
specifically to residential and commercial buildings, the sector called
``area sources'' would be a reasonable proxy for residential and
commercial buildings.\99\ The EPA document provides high and low
estimates for 2025 and 2030 at 3- and 7-percent discount rates.\100\
DOE used the same linear interpolation and extrapolation as it did with
the values for electricity generation. DOE notes that in-home emissions
may carry different monetized health risks than the risks assumed in
the monetized health benefits calculations.
---------------------------------------------------------------------------
\99\ ``Area sources'' represents all emission sources for which
states do not have exact (point) locations in their emissions
inventories. Because exact locations would tend to be associated
with larger sources, ``area sources'' would be fairly representative
of small dispersed sources like homes and businesses.
\100\ ``Area sources'' are a category in the 2018 document from
EPA, but are not used in the 2021 document cited above. See:
www.epa.gov/sites/default/files/2018-02/documents/sourceapportionmentbpttsd_2018.pdf.
---------------------------------------------------------------------------
DOE multiplied the site emissions reduction (in tons) in each year
by the associated $/ton values, and then discounted each series using
discount rates of 3 percent and 7 percent as appropriate. DOE will
continue to evaluate the monetization of avoided NOX
emissions and will make any appropriate updates for the final rule.
Additional details on the monetization of NOX and
SO2 emissions reductions are included in chapter 14 of the
TSD for this SNOPR.
M. Utility Impact Analysis
The utility impact analysis estimates several effects on the
electric power generation industry that would result from the adoption
of new or amended energy conservation standards. The utility impact
analysis estimates the changes in installed electrical capacity and
generation that would result for each TSL. The analysis is based on
published output from the NEMS associated with AEO2022. NEMS produces
the AEO Reference case, as well as a number of side cases that estimate
the economy-wide impacts of changes to energy supply and demand. For
the current analysis, impacts are quantified by comparing the levels of
electricity sector generation, installed capacity, fuel consumption and
emissions in the AEO2022 Reference case and various side cases. Details
of the methodology are provided in the appendices to chapters 13 and 15
of the TSD for this SNOPR.
The output of this analysis is a set of time-dependent coefficients
that capture the change in electricity generation, primary fuel
consumption, installed capacity and power sector emissions due to a
unit reduction in demand for a given end use. These coefficients are
multiplied by the stream of electricity savings calculated in the NIA
to provide estimates of selected utility impacts of potential new or
amended energy conservation standards.
In response to the September 2016 SNOPR, the Joint Gas Associations
commented that DOE should conduct a similar analysis on natural gas
utilities as it conducted on electric utilities to assess the impact of
the proposed efficiency requirements on that segment of the energy
industry. (Joint Gas Associations, No. 68 at pp. 3-4) The Joint Gas
Associations added that a shift from natural gas cooking products to
electric cooking products would impact the electric grid requirements.
(Id.)
DOE notes that the utility impact analysis as applied to electric
utilities only estimates the change to capacity and generation as a
result of a standard, as modeled in NEMS, and there is no gas utility
analog. DOE further notes that the impact to natural gas utility sales
is equivalent to the natural gas saved by the proposed standard and
includes those results in chapter 15 of the TSD for this SNOPR.
N. Employment Impact Analysis
DOE considers employment impacts in the domestic economy as one
factor in selecting a proposed standard. Employment impacts from new or
amended energy conservation standards include both direct and indirect
impacts. Direct employment impacts are any changes in the number of
employees of manufacturers of the products subject to standards, their
suppliers, and related service firms. The MIA addresses those impacts.
Indirect employment impacts are changes in national employment that
occur due to the shift in expenditures and capital investment caused by
the purchase and operation of more-efficient appliances. Indirect
employment impacts from standards consist of the net jobs created or
eliminated in the national economy, other than in the manufacturing
sector being regulated, caused by (1) reduced spending by consumers on
energy, (2) reduced spending on new energy supply by the utility
industry, (3) increased consumer spending on the products to which the
new standards apply and other goods and services, and (4) the effects
of those three factors throughout the economy.
One method for assessing the possible effects on the demand for
labor of such shifts in economic activity is to compare sector
employment statistics developed by the Labor Department's Bureau of
Labor Statistics (``BLS''). BLS regularly publishes its estimates of
the number of jobs per million dollars of economic activity in
different sectors of the economy, as well as the jobs created elsewhere
in the economy by this same economic activity. Data from BLS indicate
that expenditures in the utility sector generally create fewer jobs
(both directly and indirectly) than expenditures in other sectors of
the economy.\101\ There are many reasons for these differences,
including wage differences and the fact that the utility sector is more
capital-intensive and less labor-intensive than other sectors. Energy
conservation standards have the effect of reducing consumer utility
bills. Because reduced consumer expenditures for energy likely lead to
increased expenditures in other sectors of the economy, the general
effect of efficiency standards is to shift economic activity from a
less labor-intensive sector (i.e., the utility sector) to more labor-
intensive sectors (e.g., the retail and service sectors). Thus, the BLS
data suggest that net national employment may increase due to shifts in
economic activity resulting from energy conservation standards.

Laboratory: Richland, WA. PNNL-24563.
---------------------------------------------------------------------------
DOE notes that ImSET is not a general equilibrium forecasting
model, and that the uncertainties involved in projecting employment
impacts, especially changes in the later years of the analysis. Because
ImSET does not incorporate price changes, the employment effects
predicted by ImSET may over-estimate actual job impacts
[[Page 6870]]
over the long run for this rule. Therefore, DOE used ImSET only to
generate results for near-term timeframes (2027), where these
uncertainties are reduced. For more details on the employment impact
analysis, see chapter 16 of the TSD for this SNOPR.
V. Analytical Results and Conclusions
The following section addresses the results from DOE's analyses
with respect to the considered energy conservation standards for
consumer conventional cooking products. It addresses the TSLs examined
by DOE, the projected impacts of each of these levels if adopted as
energy conservation standards for consumer conventional cooking
products, and the standards levels that DOE is proposing to adopt in
this SNOPR. Additional details regarding DOE's analyses are contained
in the TSD for this SNOPR supporting this document.
A. Trial Standard Levels
In general, DOE typically evaluates potential new or amended
standards for products and equipment by grouping individual efficiency
levels for each class into TSLs. Use of TSLs allows DOE to identify and
consider manufacturer cost interactions between the product classes, to
the extent that there are such interactions, and market cross
elasticity from consumer purchasing decisions that may change when
different standard levels are set.
In the analysis conducted for this SNOPR, DOE analyzed the benefits
and burdens of three TSLs for consumer conventional cooking products.
DOE developed TSLs that combine efficiency levels for each analyzed
product class. DOE presents the results for the TSLs in this document,
while the results for all efficiency levels that DOE analyzed are in
the TSD for this SNOPR.
Table V.1 through Table V.3 present the TSLs and the corresponding
efficiency levels that DOE has identified for potential amended energy
conservation standards for consumer conventional cooking products. TSL
3 represents the maximum technologically feasible (max-tech) energy
efficiency for all product classes. TSL 2 represents an intermediate
TSL. TSL 1 is configured with the minimum efficiency improvement in
each product class corresponding to electronic controls for electric
cooking tops, optimized burners for gas cooking tops, and switch mode
power supplies for ovens.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
DOE constructed the TSLs for this SNOPR to include ELs
representative of ELs with similar characteristics (i.e., using similar
technologies and/or efficiencies, and having roughly comparable
equipment availability). The use of representative ELs provided for
greater distinction between the TSLs. While representative ELs were
included in the TSLs, DOE considered all efficiency levels as part of
its analysis.\103\
---------------------------------------------------------------------------
\103\ Efficiency levels that were analyzed for this SNOPR are
discussed in section IV.C of this document. Results by efficiency
level are presented in chapters 8, 10, and 12 of the TSD for this
SNOPR.
---------------------------------------------------------------------------
B. Economic Justification and Energy Savings
1. Economic Impacts on Individual Consumers
DOE analyzed the economic impacts on consumer conventional cooking
products consumers by looking at the effects that potential new and
amended standards at each TSL would have on
[[Page 6871]]
the LCC and PBP. DOE also examined the impacts of potential standards
on selected consumer subgroups. These analyses are discussed in the
following sections.
a. Life-Cycle Cost and Payback Period
In general, higher-efficiency products affect consumers in two
ways: (1) purchase price increases and (2) annual operating costs
decrease. Inputs used for calculating the LCC and PBP include total
installed costs (i.e., product price plus installation costs), and
operating costs (i.e., annual energy use, energy prices, energy price
trends, repair costs, and maintenance costs). The LCC calculation also
uses product lifetime and a discount rate. Chapter 8 of the TSD for
this SNOPR provides detailed information on the LCC and PBP analyses.
Table V.4 through Table V.25 show the LCC and PBP results for the
TSLs considered for each product class. In the first of each pair of
tables, the simple payback is measured relative to the baseline
product. In the second table, impacts are measured relative to the
efficiency distribution in the no-new-standards case in the compliance
year (see section IV.F.8 of this document). Because some consumers
purchase products with higher efficiency in the no-new-standards case,
the average savings are less than the difference between the average
LCC of the baseline product and the average LCC at each TSL. The
savings refer only to consumers who are affected by a standard at a
given TSL. Those who already purchase a product with efficiency at or
above a given TSL are not affected. Consumers for whom the LCC
increases at a given TSL experience a net cost.

b. Consumer Subgroup Analysis
In the consumer subgroup analysis, DOE estimated the impact of the
considered TSLs on low-income households and senior-only households.
Table V.26 through Table V.36 compare the average LCC savings and PBP
at each efficiency level for the consumer subgroups with similar
metrics for the entire consumer sample for each product class. In most
cases, the average LCC savings and PBP for low-income households and
senior-only households at the considered efficiency levels are not
substantially different from the average for all households. Usage data
from RECS 2015 indicate that low-income households have a similar usage
pattern to all households which leads to similar results. Senior-only
households were found to use cooking products less frequently than the
general population resulting in slightly lower savings. Chapter 11 of
the TSD for this SNOPR presents the complete LCC and PBP results for
the subgroups.

In the absence to data specific to each consumer subgroup, DOE
assumed the efficiency distribution developed for the reference case
analysis (see section IV.F.8 of this document for details). However,
for gas cooking tops, this likely overestimates the negative impact to
low-income households that are more likely to purchase traditional
residential-style gas cooking tops which tend to have fewer high output
burners and slimmer grates relative to commercial-style gas cooking
tops. These households are more likely to purchase products above the
baseline at EL 1 or EL 2. As both EL 1 and EL 2 have the same installed
cost (see Table V.5), a standard for these consumers would not lead to
an increase in purchase price and would result in operating cost
savings for consumers that purchase EL 1 in the no-new-standards case
and EL 2 in a standards case.
c. Rebuttable Presumption Payback
As discussed in section III.F.2 of this document, EPCA establishes
a rebuttable presumption that an energy conservation standard is
economically
[[Page 6879]]
justified if the increased purchase cost for a product that meets the
standard is less than three times the value of the first-year energy
savings resulting from the standard. In calculating a rebuttable
presumption payback period for each of the considered TSLs, DOE used
discrete values, and, as required by EPCA, based the energy use
calculation on the DOE test procedure for consumer conventional cooking
products. In contrast, the PBPs presented in section V.B.1.a of this
document were calculated using distributions that reflect the range of
energy use in the field.
Table V.37 presents the rebuttable-presumption payback periods for
the considered TSLs for consumer conventional cooking products. While
DOE examined the rebuttable-presumption criterion, it considered
whether the standard levels considered for the SNOPR are economically
justified through a more detailed analysis of the economic impacts of
those levels, pursuant to 42 U.S.C. 6295(o)(2)(B)(i), that considers
the full range of impacts to the consumer, manufacturer, Nation, and
environment. The results of that analysis serve as the basis for DOE to
definitively evaluate the economic justification for a potential
standard level, thereby supporting or rebutting the results of any
preliminary determination of economic justification.

2. Economic Impacts on Manufacturers
DOE performed an MIA to estimate the impact of new and amended
energy conservation standards on manufacturers of consumer conventional
cooking products. The following section describes the expected impacts
on manufacturers at each considered TSL. Chapter 12 of the TSD for this
SNOPR explains the analysis in further detail.
a. Industry Cash Flow Analysis Results
In this section, DOE provides GRIM results from the analysis, which
examines changes in the industry that would result from the analyzed
energy conservation standards. The following tables summarize the
estimated financial impacts (represented by changes in INPV) of
potential new and amended energy conservation standards on
manufacturers of consumer conventional cooking products, as well as the
conversion costs that DOE estimates manufacturers of consumer
conventional cooking products would incur at each TSL. To evaluate the
range of cash-flow impacts on the consumer conventional cooking product
industry, DOE modeled two scenarios using different assumptions that
correspond to the range of anticipated market responses to new and
amended energy conservation standards: (1) the preservation of gross
margin scenario and (2) the preservation of operating profit scenario.
In the preservation of gross margin scenario, consumer conventional
cooking product manufacturers are able to maintain their margins (as a
percentage), even as the MPCs of consumer conventional cooking products
increase due to energy conservation standards. The same uniform margin
of 17 percent is applied across all efficiency levels in the
preservation of gross margin.\104\ In the preservation of operating
profit scenario, manufacturers are not able to maintain their original
margins of 17 percent, in the standards cases. Instead, manufacturers
are only able to maintain the same operating profit (in absolute
dollars) in the standards cases as in the no-new-standards case,
despite higher MPCs.
---------------------------------------------------------------------------
\104\ The gross margin percentage of 17 percent is based on a
manufacturer markup of 1.20.
---------------------------------------------------------------------------
Each of the modeled scenarios results in a unique set of cash-flows
and corresponding industry values at each TSL for consumer conventional
cooking product manufacturers. In the following discussion, the INPV
results refer to the difference in industry value between the no-new-
standards case and each standards case resulting from the sum of
discounted cash-flows from 2022 through 2056. To provide perspective on
the short-run cash-flow impact, DOE includes in the discussion of
results a comparison of free cash flow between the no-new-standards
case and the standards case at each TSL in the year before new and
amended standards are required.
DOE presents the range in INPV for consumer conventional cooking
product manufacturers in Table V.38 and Table V.39.

----------------------------------------------------------------------------------------------------------------
* Parentheses indicate negative values. Numbers may not sum exactly due to rounding.
At TSL 1, DOE estimates impacts on INPV will range from -$105.1
million to -$100.7 million, which represents a change of -6.5 percent
to -6.3. percent, respectively. At TSL 1, industry free cash-flow
decrease to $90.3 million, which represents a decrease of approximately
42.5 percent, compared to the no-new-standards case value of $132.9
million in 2026, the year before the estimated compliance date.
TSL 1 would set the energy conservation standard at baseline for
the electric open (coil) element cooking top product class and at EL 1
for all other product classes. DOE estimates that 100 percent of the
electric open (coil) element cooking top shipments, 80 percent of the
electric smooth element cooking top shipments, 52 percent of the gas
cooking top shipments, 95 percent of the electric oven shipments, and
96 percent of the gas oven shipments would already meet or exceed the
efficiency levels required at TSL 1 in 2027.
At TSL 1, DOE expects consumer conventional cooking product
manufacturers to incur approximately $45.5 million in product
conversion costs to redesign all non-compliant cooking top models and
oven models, as well as to test all (both compliant and newly
redesigned) cooking top models to DOE's cooking top test procedure.
Additionally, consumer conventional cooking product manufacturers would
incur approximately $58.5 million in capital conversion costs to
purchase new tooling and equipment necessary to produce all electric
smooth element cooking top models and all oven models to use switch-
mode power supplies and to purchase new molds for grates and burners
for gas cooking top models that would not meet this energy conservation
standard.
At TSL 1, the shipment-weighted average MPC for consumer
conventional cooking products slightly increases by 0.5 percent
relative to the no-new-standards case shipment-weighted average MPC in
2027. In the preservation of gross margin scenario, manufacturers can
fully pass on this slight cost increase. The slight increase in
shipment weighted average MPC is outweighed by the $104.1 million in
conversion costs, causing a moderately negative change in INPV at TSL 1
under the preservation of gross margin scenario.
Under the preservation of operating profit scenario, manufacturers
earn the same per-unit operating profit as would be earned in the no-
new-standards case, but manufacturers do not earn additional profit
from their investments or higher MPCs. In this scenario, the 0.5
percent shipment weighted average MPC increase results in a reduction
in the margin after the analyzed compliance year. This reduction in the
margin and the $104.1 million in conversion costs incurred by
manufacturers cause a moderately negative change in INPV at TSL 1 under
the preservation of operating profit scenario.
At TSL 2, DOE estimates impacts on INPV will range from -$154.8
million to -$150.4 million, which represents a change of -9.6 percent
to -9.4 percent, respectively. At TSL 2, industry free cash-flow
decrease to $60.7 million, which represents a decrease of approximately
72.2 percent, compared to the no-new-standards case value of $132.9
million in 2026, the year before the estimated compliance date.
TSL 2 would set the energy conservation standard at baseline for
the electric open (coil) element cooking top product class; at EL 1 for
the electric smooth element cooking top and for all oven product
classes (electric and gas); and at EL 2 for the gas cooking top product
class, which represents max-tech for this product class. DOE estimates
that 100 percent of the electric open (coil) element cooking top
shipments, 80 percent of the electric smooth element cooking top
shipments, 4 percent of the gas cooking top shipments, 95 percent of
the electric oven shipments, and 96 percent of the gas oven shipments
would already meet or exceed the efficiency levels required at TSL 2 in
2027.
At TSL 2, DOE expects consumer conventional cooking product
manufacturers to incur approximately $109.9 million in product
conversion costs at this TSL. This includes testing costs and product
redesign costs. The majority of the product conversion costs
[[Page 6881]]
are for gas cooking top manufacturers to redesign non-compliant gas
cooking top models to meet this energy conservation standard, as well
as to test all (both compliant and newly redesigned) cooking top models
to DOE's cooking top test procedure. Additionally, consumer
conventional cooking product manufacturers would incur approximately
$73.5 million in capital conversion costs to purchase new tooling and
equipment necessary to produce all electric smooth element cooking top
models and all oven models to use switch-mode power supplies and to
purchase new molds for grates and burners for gas cooking top models
that would not meet this energy conservation standard.
At TSL 2, the shipment-weighted average MPC for consumer
conventional cooking products slightly increases by 0.5 percent
relative to the no-new-standards case shipment-weighted average MPC in
2027. In the preservation of gross margin scenario, manufacturers can
fully pass on this slight cost increase. The slight increase in
shipment weighted average MPC is outweighed by the $183.4 million in
conversion costs, causing a moderately negative change in INPV at TSL 2
under the preservation of gross margin scenario.
Under the preservation of operating profit scenario, the 0.5
percent shipment weighted average MPC increase results in a reduction
in the margin after the analyzed compliance year. This reduction in the
manufacturer markup and the $183.4 million in conversion costs incurred
by manufacturers cause a moderately negative change in INPV at TSL 2
under the preservation of operating profit scenario.
At TSL 3, DOE estimates impacts on INPV will range from -$1,368.6
million to -$1,185.1 million, which represents a change of -85.2
percent to -73.8 percent, respectively. At TSL 3, industry free cash-
flow decrease to -$666.2 million, which represents a decrease of
approximately 799.0 percent, compared to the no-new-standards case
value of $132.9 million in 2026, the year before the estimated
compliance date.
TSL 3 would set the energy conservation standard at baseline for
the electric open (coil) element cooking top product class; at EL 2 for
the gas cooking top product class and for all the gas oven product
classes (standard and self-clean); and at EL 3 for the electric smooth
element cooking top product class and for all the electric oven product
classes (standard and self-clean). This represents max-tech for all
product classes. DOE estimates that 100 percent of the electric open
(coil) element cooking top shipments, 5 percent of the electric smooth
element cooking top shipments, 4 percent of the gas cooking top
shipments, zero percent of the electric standard oven (freestanding and
built-in) shipments, zero percent of the electric self-clean oven
(freestanding) shipments, 2 percent of the electric self-clean (built-
in) shipments, 62 percent of gas standard oven (freestanding)
shipments, 38 percent of the gas standard oven (built-in) shipments, 93
percent of the gas self-clean oven (freestanding) shipments, and 77
percent of the gas self-clean (built-in) shipments would already meet
the efficiency levels required at TSL 3 in 2027.
At TSL 3, DOE expects consumer conventional cooking product
manufacturers to incur approximately $1,401.6 million in product
conversion costs at this TSL. This includes testing costs and product
redesign costs. At this TSL electric smooth element cooking top
manufacturers would have to completely redesign most of their electric
smooth element cooking top models to use induction technology. Electric
oven manufacturers would have to completely redesign all of their
electric oven models to use oven separators. Additionally, consumer
conventional cooking product manufacturers would incur approximately
$444.8 million in capital conversion costs to purchase new tooling and
equipment necessary to produce the numerous redesigned cooking top and
oven models at this TSL.
At TSL 3, the shipment-weighted average MPC for consumer
conventional cooking products significantly increases by 17.7 percent
relative to the no-new-standards case shipment-weighted average MPC in
2027. In the preservation of gross margin scenario, manufacturers can
fully pass on this cost increase. The significant increase in shipment
weighted average MPC is outweighed by the $1,846.4 million in
conversion costs, causing a significantly negative change in INPV at
TSL 3 under the preservation of gross margin scenario.
Under the preservation of operating profit scenario, the 17.7
percent shipment weighted average MPC increase results in a reduction
in the margin after the analyzed compliance year. This reduction in the
margin and the $1,846.4 million in conversion costs incurred by
manufacturers cause a significantly negative change in INPV at TSL 3
under the preservation of operating profit scenario.
b. Direct Impacts on Employment
To quantitatively assess the potential impacts of new and amended
energy conservation standards on direct employment in the consumer
conventional cooking products industry, DOE used the GRIM to estimate
the domestic labor expenditures and number of direct employees in the
no-new-standards case and in each of the standards cases (i.e., TSLs)
during the analysis period.
Production employees are those who are directly involved in
fabricating and assembling products within a manufacturer facility.
Workers performing services that are closely associated with production
operations, such as materials handling tasks using forklifts, are
included as production labor, as well as line supervisors.
DOE used the GRIM to calculate the number of production employees
from labor expenditures. DOE used statistical data from the U.S. Census
Bureau's 2019 Annual Survey of Manufacturers (``ASM'') and the results
of the engineering analysis to calculate industry-wide labor
expenditures. Labor expenditures related to product manufacturing
depend on the labor intensity of the product, the sales volume, and an
assumption that wages remain fixed in real terms over time. The total
labor expenditures in the GRIM were then converted to domestic
production employment levels by dividing production labor expenditures
by the annual payment per production worker.
Non-production employees account for those workers that are not
directly engaged in the manufacturing of the covered products. This
could include sales, human resources, engineering, and management. DOE
estimated non-production employment levels by multiplying the number of
consumer conventional cooking product workers by a scaling factor. The
scaling factor is calculated by taking the ratio of the total number of
employees, and the total production workers associated with the
industry NAICS code 335220, which covers consumer conventional cooking
product manufacturing.
The employment impacts shown in Table V.40 represent the potential
domestic production employment that could result following the new and
amended energy conservation standards. The upper bound of the results
estimates the maximum change in the number of production workers that
could occur after compliance with the new and amended energy
conservation standards when assuming that manufacturers continue to
produce
[[Page 6882]]
the same scope of covered products in the same production facilities.
It also assumes that domestic production does not shift to lower labor-
cost countries. Because there is a risk of manufacturers evaluating
sourcing decisions in response to the new and amended energy
conservation standards, the lower bound of the employment results
includes DOE's estimate of the total number of U.S. production workers
in the industry who could lose their jobs if some existing domestic
production were moved outside of the United States. While the results
present a range of domestic employment impacts following 2027, the
following sections also include qualitative discussions of the
likelihood of negative employment impacts at the various TSLs.
Using 2019 ASM data and interviews with manufacturers, DOE
estimates that approximately 60 percent of the consumer conventional
cooking products sold in the United States are manufactured
domestically. With this assumption, DOE estimates that in the absence
of new and amended energy conservation standards, there would be
approximately 4,322 domestic production workers involved in
manufacturing consumer conventional cooking products in 2027. Table
V.40 shows the range of the impacts of the new and amended energy
conservation standards on U.S. production workers in the consumer
conventional cooking product industry.

----------------------------------------------------------------------------------------------------------------
* DOE presents a range of potential impacts. Numbers in parentheses indicate negative values.
At the upper end of the range, all examined TSLs show an increase
in the number of domestic production workers for consumer conventional
cooking products. The upper end of the range represents a scenario
where manufacturers increase production hiring due to the increase in
the labor associated with adding the required components to make
consumer conventional cooking products more efficient. However, as
previously stated, this assumes that in addition to hiring more
production employees, all existing domestic production would remain in
the United States and not shift to lower labor-cost countries.
At the lower end of the range, all examined TSLs show either no
change in domestic production employment or a decrease in domestic
production employment. The lower end of the domestic employment range
assumes that gas cooking top domestic production employment does not
change at any TSL. Manufacturing more efficient gas cooking tops by
optimizing the burner and improving grates would not impact the
location where production occurs for this product class. Additionally,
this lower range assumes that TSLs set at EL 1 for all oven product
classes and the electric smooth element cooking top product class would
not change the domestic production employment. EL 1 would require SMPSs
for all oven product classes and can be achieved using low-standby-loss
electronic controls for the electric smooth element cooking top product
class. The majority of manufacturers already use SMPSs in their ovens
and are able to meet the efficiency requirements at EL 1 for the
electric smooth element cooking top product class. Adding these standby
features to models currently not using these features would not change
the location where production occurs for these product classes.
At the lower end of the range, DOE estimated that up to 50 percent
of domestic production employment for the electric smooth element
cooking top product class could be relocated abroad at max-tech.
Additionally, DOE estimated that up to 25 percent of domestic
production employment for the oven product classes could be relocated
abroad at max-tech. DOE estimates that there would be approximately 584
domestic production employees involved in the production of electric
smooth element cooking tops and 3,102 domestic production employees
involved in the production covering all oven product classes in 2027 in
the no-new-standards case. Using these values to estimate the lower end
of the range, DOE estimated that up to 1,068 domestic production
employees could be eliminated at TSL 3 (due to standards being set at
max-tech for the electric smooth element cooking top product class and
for all oven product classes).\105\
---------------------------------------------------------------------------
\105\ 584 x 50% + 3,102 x 25% = 1,067.5.
---------------------------------------------------------------------------
DOE provides a range of potential impacts to domestic production
employment as each manufacturer would make a business decision that
best suits their individual product needs. However, manufacturers
stated during interviews that due to the larger size of most consumer
conventional cooking products, there are few units that are
manufactured and shipped from far distances such as Asia or Europe. The
vast majority of consumer conventional cooking products are currently
made in North America. Some manufacturers stated that even significant
changes to production lines would not cause them to shift their
production abroad, as several manufacturers either only produce
consumer conventional cooking products domestically or have made
significant investments to continue to produce consumer conventional
cooking products domestically.
DOE requests comment on the estimated potential domestic employment
impacts on consumer conventional cooking product manufacturers
presented in this SNOPR.
c. Impacts on Manufacturing Capacity
Manufacturers stated that any standard requiring induction heating
technology for electric smooth element cooking tops would be very
difficult to meet since there are approximately 5 percent of shipments
currently using this technology. Additionally, any standards requiring
oven separators for the electric oven product classes would be very
difficult to meet since that would require completely redesigning the
oven cavity of almost every electric oven model currently on the
market.
All other ELs analyzed require making incremental improvements to
existing designs and should not present any manufacturing capacity
constraints given the 3-year compliance period proposed in this SNOPR.
[[Page 6883]]
DOE requests comment on the potential manufacturing capacity
constraints placed on consumer conventional cooking product
manufacturers at the TSLs presented in this SNOPR.
d. Impacts on Subgroups of Manufacturers
Using average cost assumptions to develop an industry cash-flow
estimate may not be adequate for assessing differential impacts among
manufacturer subgroups. Small manufacturers, niche product
manufacturers, and manufacturers exhibiting cost structures
substantially different from the industry average could be affected
disproportionately. DOE analyzed the impacts on small businesses in
section VI.B of this document. DOE also identified the commercial-style
manufacturer subgroup as a potential manufacturer subgroup that could
be adversely impacted by energy conservation standards based on the
results of the industry characterization.
The commercial-style manufacturer subgroup consists of consumer
conventional cooking product manufacturers that primarily sell gas
cooking tops, gas ovens, and electric self-clean ovens marketed as
commercial-style, either as a stand-alone product or as a component of
a conventional range. For the cooking top product classes, while
commercial-style manufacturers do not produce electric open (coil)
element cooking tops, some commercial-style manufacturers do produce
electric smooth element cooking tops. Of those commercial-style
manufacturers that do produce electric smooth element cooking tops, all
these manufacturers have products that use induction technology and
would be able to meet the max-tech for this product class.
Commercial-style manufacturers would likely face more difficulty
meeting potential standards set for the gas cooking top product class
than other consumer conventional cooking product manufacturers.
However, as previously stated in IV.C.1, all analyzed ELs for the gas
cooking top product class are achievable with continuous cast-iron
grates and at least one HIR burner. Therefore, while commercial-style
manufacturers would likely have to redesign a higher portion of their
gas cooking top models compared to other consumer conventional cooking
product manufacturers, all ELs for the gas cooking top product class
are achievable for commercial-style manufacturers.
For the oven product classes, the vast majority of commercial-style
electric and gas ovens already use SMPSs in their ovens and would not
have difficulty meeting potential standard levels requiring SMPSs for
any oven product classes. Additionally, commercial-style manufactures
typically have a higher percentage of gas oven models that use forced
convention than other consumer conventional cooking product
manufacturers. However, like the rest of the market, there are very
few, if any, commercial-style electric ovens equipped with an oven
separator and it would be difficult for commercial-style manufacturers
to convert all of their oven cavities into ovens equipped with an oven
separator.
DOE requests comment on the potential impacts on commercial-style
manufacturers at the TSLs presented in this SNOPR.
e. Cumulative Regulatory Burden
One aspect of assessing manufacturer burden involves looking at the
cumulative impact of multiple DOE standards and the product-specific
regulatory actions of other Federal agencies that affect the
manufacturers of a covered product or equipment. While any one
regulation may not impose a significant burden on manufacturers, the
combined effects of several existing or impending regulations may have
serious consequences for some manufacturers, groups of manufacturers,
or an entire industry. Assessing the impact of a single regulation may
overlook this cumulative regulatory burden. In addition to energy
conservation standards, other regulations can significantly affect
manufacturers' financial operations. Multiple regulations affecting the
same manufacturer can strain profits and lead companies to abandon
product lines or markets with lower expected future returns than
competing products. For these reasons, DOE conducts an analysis of
cumulative regulatory burden as part of its rulemakings pertaining to
appliance efficiency.
DOE evaluates product-specific regulations that will take effect
approximately 3 years before or after the estimated 2027 compliance
date of any new and amended energy conservation standards for consumer
conventional cooking products. This information is presented in Table
V.41.

3. National Impact Analysis
This section presents DOE's estimates of the national energy
savings and the NPV of consumer benefits that would result from each of
the TSLs considered as potential amended standards.
a. Significance of Energy Savings
To estimate the energy savings attributable to potential amended
standards for consumer conventional cooking products, DOE compared
their energy consumption under the no-new-standards case to their
anticipated energy consumption under each TSL. The savings are measured
over the entire lifetime of products purchased in the 30-year period
that begins in the year of anticipated compliance with amended
standards (2027-2056). Table V.42 presents DOE's projections of the
national energy savings for each TSL considered for consumer
conventional cooking products. The savings were calculated using the
approach described in section IV.H.3 of this document.

----------------------------------------------------------------------------------------------------------------
OMB Circular A-4 \113\ requires agencies to present analytical
results, including separate schedules of the monetized benefits and
costs that show the type and timing of benefits and costs. Circular A-4
also directs agencies to consider the variability of key elements
underlying the estimates of benefits and costs. For this rulemaking,
DOE undertook a sensitivity analysis using 9 years, rather than 30
years, of product shipments. The choice of a 9-year period is a proxy
for the timeline in EPCA for the review of certain energy conservation
standards and potential revision of and compliance with such revised
standards.\114\ The review timeframe established in EPCA is generally
not synchronized with the product lifetime, product manufacturing
cycles, or other factors specific to consumer conventional cooking
products. Thus, such results are presented for informational purposes
only and are not indicative of any change in DOE's analytical
methodology. The NES sensitivity analysis results based on a 9-year
analytical period are presented in Table V.43. The impacts are counted
over the lifetime of consumer conventional cooking products purchased
in 2027-2035.

Regulatory Analysis. September 17, 2003.
obamawhitehouse.archives.gov/omb/circulars_a004_a-4/ (last accessed
July 11, 2022).
\114\ Section 325(m) of EPCA requires DOE to review its
standards at least once every 6 years, and requires, for certain
products, a 3-year period after any new standard is promulgated
before compliance is required, except that in no case may any new
standards be required within 6 years of the compliance date of the
previous standards. While adding a 6-year review to the 3-year
compliance period adds up to 9 years, DOE notes that it may
undertake reviews at any time within the 6-year period and that the
3-year compliance date may yield to the 6-year backstop. A 9-year
analysis period may not be appropriate given the variability that
occurs in the timing of standards reviews and the fact that for some
products, the compliance period is 5 years rather than 3 years.

b. Net Present Value of Consumer Costs and Benefits
DOE estimated the cumulative NPV of the total costs and savings for
consumers that would result from the TSLs considered for consumer
conventional cooking products. In accordance with OMB's guidelines on
regulatory analysis,\115\ DOE calculated NPV using both a 7-percent and
a 3-percent real discount rate. Table V.44 shows the consumer NPV
results with impacts counted over the lifetime of products purchased in
2027-2056.

criteria.

The previous results reflect the use of a default trend to estimate
the change in price for consumer conventional cooking products over the
analysis period (see section IV.F.1 of this document). DOE also
conducted a sensitivity analysis that considered one scenario with a
lower rate of price decline than the reference case and one scenario
with a higher rate of price decline than the reference case. The
results of these alternative cases are presented in appendix 10C of the
TSD for this SNOPR. In the high-price-decline case, the NPV of consumer
benefits is higher than in the default case. In the low-price-decline
case, the NPV of consumer benefits is lower than in the default case.
In each case, net benefits remain positive.
c. Indirect Impacts on Employment
It is estimated that that amended energy conservation standards for
consumer conventional cooking products would reduce energy expenditures
for consumers of those products, with the resulting net savings being
redirected to other forms of economic activity. These expected shifts
in spending and economic activity could affect the demand for labor. As
described in section IV.N of this document, DOE used an input/output
model of the U.S. economy to estimate indirect employment impacts of
the TSLs that DOE considered. There are uncertainties involved in
projecting employment impacts, especially changes in the later years of
the analysis. Therefore, DOE generated results for near-term timeframes
(2027), where these uncertainties are reduced.
The results suggest that the proposed standards would be likely to
have a negligible impact on the net demand for labor in the economy.
The net change in jobs is so small that it would be imperceptible in
national labor statistics and might be offset by other, unanticipated
effects on employment. Chapter 16 of the TSD for this SNOPR presents
detailed results regarding anticipated indirect employment impacts.
4. Impact on Utility or Performance of Products
As discussed in section IV.C of this document, DOE has tentatively
concluded that the standards proposed in this SNOPR would not lessen
the utility or performance of the consumer conventional cooking
products under consideration in this rulemaking. Manufacturers of these
products currently offer units that meet or exceed the proposed
standards.
AHAM stated that the introduction of any new standards could have a
significant impact on the utility of cooking products by, for example,
potentially lowering burner input rates or requiring changes that would
result in less sturdy grates. (AHAM, No. 84 at p. 4)
As discuss in section IV.C of this document, when evaluating higher
ELs
[[Page 6886]]
for gas cooking tops, DOE ensured that all potential standard levels
would maintain the ability for cooking tops to offer at least one HIR
burner and continuous cast-iron grates.
5. Impact of Any Lessening of Competition
DOE considered any lessening of competition that would be likely to
result from new or amended standards. As discussed in section III.F.1.e
of this document, the Attorney General determines the impact, if any,
of any lessening of competition likely to result from a proposed
standard, and transmits such determination in writing to the Secretary,
together with an analysis of the nature and extent of such impact. To
assist the Attorney General in making this determination, DOE has
provided DOJ with copies of this SNOPR and the accompanying TSD for
review. DOE will consider DOJ's comments on the proposed rule in
determining whether to proceed to a final rule. DOE will publish and
respond to DOJ's comments in that document.
As discussed in chapter 3 of the TSD for this SNOPR, DOE estimates
that there are approximately 34 manufacturers of consumer conventional
cooking products supplying the domestic market, and that three major
manufacturers represent roughly 85 percent of the market. The major
manufacturers offer a full array of appliances under multiple brands at
a range of price points. Other manufacturers offer a much more limited
set of products that are focused on the higher end premium products or
other consumer niches.
The consumer conventional cooking product market can be divided
into three sub-markets: a smaller entry level ``value'' consumer
conventional cooking product market; a mass-market consumer
conventional cooking product market; and a premium commercial-style
consumer conventional cooking product market. The smaller entry level
consumer conventional cooking product market typically consists of
ovens, cooking tops, and ranges that have a width of 30'' or less.
These products typically compete on price, as consumers that purchase
these products are price sensitive. The mass-market consumer
conventional cooking product market makes up the vast majority of the
consumer conventional cooking product market. These are ovens, cooking
tops, and ranges that are sold in big box retail stores and larger
internet retailers. The premium commercial-style consumer conventional
cooking product market typically consists of ovens, cooking tops, and
ranges, that have a width of 30'' or larger that have gas cooking tops,
gas ovens, or electric self-clean ovens marketed as commercial-style,
either as a stand-alone product or as a component of a conventional
range. These products typically do compete on brand and features as
well as price and are significantly more expensive than the mass-
produced consumer conventional cooking products.
As discussed in section III.C of this document, there is currently
no test procedure for conventional ovens and efficiency gains can be
obtained from product redesigns of design improvements at low
incremental manufacturing costs.
For products sold in all three consumer conventional cooking
product sub-markets, meeting energy conservation standards for consumer
conventional ovens set at EL 1 (TSL 1 and TSL 2) would not present a
significant challenge for any consumer conventional cooking product
manufacturer. Based on the shipments analysis used in the NIA, DOE
estimates that approximately 95 percent of ovens will meet or exceed EL
1 by the estimated compliance date. The remaining five percent of the
market would need to purchase switch-mode power supplies to be used in
their consumer conventional ovens. Switch-mode power supplies are
widely used and readily available and constitute a minor increase in
production costs for the consumer conventional ovens that do not
currently use switch-mode power supplies.
As discussed in section III.C of this document, although there is a
new test procedure for conventional cooking tops, there is no current
performance standard. As a result, conventional cooking top design may
not be optimized to the IAEC metric and efficiency gains can be
obtained from product redesigns at low incremental manufacturing costs.
Regarding standards for consumer conventional cooking tops, the
majority of smaller entry level ``value'' consumer conventional cooking
products would not be significantly impacted by any energy conservation
standards set below max-tech for consumer conventional cooking tops.
The majority of consumer conventional cooking tops sold in the smaller
entry level ``value'' consumer conventional cooking product market
either have electric open (coil) element cooking tops or gas-cooking
tops with thinner non-continuous grates. DOE is only considering a
baseline efficiency level for electric open (coil) element cooking tops
that can be meet by all products. Gas cooking tops with thinner non-
continuous grates typically are at max-tech. It is unlikely that many
gas cooking tops sold in the smaller entry level ``value'' consumer
conventional cooking product market would have to redesign their
products to meet standards set at any efficiency level.
For the mass-market consumer conventional cooking product market,
most electric smooth element cooking tops will meet or exceed standards
set at EL 1 (TSL 1 and TSL 2). The majority of electric smooth element
cooking tops that are at baseline, EL 1, and EL 2 (i.e., not the
electric smooth cooking tops that use induction technology, which are
electric smooth element cooking tops meting max-tech) are sold in the
mass-market consumer conventional cooking product market. Based on the
shipments analysis used in the NIA, DOE estimates that approximately 80
percent of electric smooth element cooking tops will meet or exceed EL
1 by the estimated compliance date.
Most of the gas cooking top products sold in the mass-market
consumer conventional cooking product market would have to be
redesigned to meet standards set at max-tech (TSL 2 and TSL 3). Based
on the shipments analysis used in the NIA, DOE estimates that
approximately 96 percent of gas cooking tops will need to be redesigned
to meet standards set at max-tech by the estimated compliance date.
The premium commercial-style consumer conventional cooking product
market typically uses either electric cooking tops that use induction
technology and are at max-tech for the electric smooth element cooking
top product class or gas cooking tops. All electric smooth element
cooking tops using induction technology would be able to meet standards
set at max-tech for the electric smooth element product class. Premium
commercial-style manufacturers would likely face more difficulty
meeting potential standards set for the gas cooking top product class
than other consumer conventional cooking product manufacturers.
However, as previously stated in section IV.C.1 of this document, all
analyzed ELs for the gas cooking top product class are achievable with
continuous cast-iron grates and at least one HIR burner. Therefore,
while commercial-style manufacturers would likely have to redesign a
higher portion of their gas cooking top models compared to other
consumer conventional cooking product manufacturers, all ELs for the
gas cooking top product class are achievable for commercial-style
manufacturers. Additionally, premium commercial-style consumer
conventional cooking products typically are not as cost sensitive as
the other consumer
[[Page 6887]]
conventional cooking product markets. Premium commercial-style consumer
conventional cooking product typically sell for more than twice the
cost of mass-market consumer conventional cooking products. DOE
anticipates that premium commercial-style consumer conventional cooking
product manufacturers are more likely to be able to pass on cost
increases to their customers than the other consumer conventional
cooking product markets.
Overall, DOE does not anticipate that energy conservation standards
set at TSL 1 or TSL 2 would significantly alter the current market
structure that consumer conventional cooking products are currently
sold.
DOE does not expect the proposed rule to increase the concentration
in an already concentrated market. DOE understands that barriers to
entry or expansion associated with manufacturing and selling cooking
products is high particularly in the mass-market segment. The cost of
developing brand recognition; achieving manufacturing scale to lower
production costs; and developing a distribution network, are all
significant challenges. The industry has responded by segmenting the
market into more focused markets that allow differentiation and
competition on factors other than price. For the reasons described in
this section, the proposed rule likely would not alter the competitive
balance or market structure of the consumer conventional cooking
product industry.
DOE invites comment from the public regarding the competitive
impacts that are likely to result from this proposed rule. In addition,
stakeholders may also provide comments separately to DOJ regarding
these potential impacts. See the ADDRESSES section for information to
send comments to DOJ.
6. Need of the Nation To Conserve Energy
Enhanced energy efficiency, where economically justified, improves
the Nation's energy security, strengthens the economy, and reduces the
environmental impacts (costs) of energy production.
DOE seeks comment on the potential impacts on energy security as a
result of amended standards for cooking products, which reduce the use
of natural gas as a result of more-efficient cooking appliances.
Reduced in-home gas combustion may deliver additional health
benefits to consumers and their families by reducing exposure to
various pollutants. Reduced electricity demand due to energy
conservation standards is also likely to reduce the cost of maintaining
the reliability of the electricity system, particularly during peak-
load periods. Chapter 15 in the TSD for this SNOPR presents the
estimated impacts on electricity generating capacity, relative to the
no-new-standards case, for the TSLs that DOE considered in this
rulemaking.
Energy conservation resulting from potential energy conservation
standards for consumer conventional cooking products is expected to
yield environmental benefits in the form of reduced emissions of
certain air pollutants and greenhouse gases. Table V.46 provides DOE's
estimate of cumulative emissions reductions expected to result from the
TSLs considered in this rulemaking. The emissions were calculated using
the multipliers discussed in section IV.K of this document. DOE reports
annual emissions reductions for each TSL in chapter 13 of the TSD for
this SNOPR.

As part of the analysis for this rulemaking, DOE estimated monetary
benefits likely to result from the reduced emissions of CO2
that DOE estimated for each of the considered TSLs for consumer
conventional cooking products. Section IV.L of this document discusses
the SC-CO2 values that DOE used. Table V.47 presents the
value of CO2 emissions reduction at each TSL for each of the
SC-CO2 cases. The time-series of annual values is presented
for the proposed TSL in chapter 14 of the TSD for this SNOPR.

for consumer conventional cooking products. Table V.48 presents the
value of the CH4 emissions reduction at each TSL, and Table

DOE is well aware that scientific and economic knowledge about the
contribution of CO2 and other GHG emissions to changes in
the future global climate and the potential resulting damages to the
global and U.S. economy continues to evolve rapidly. DOE, together with
other Federal agencies, will continue to review methodologies for
estimating the monetary value of reductions in CO2 and other
GHG emissions. This ongoing review will consider the comments on this
subject that are part of the public record for this and other
rulemakings, as well as other methodological assumptions and issues.
DOE notes that the proposed standards would be economically justified
even without inclusion of monetized benefits of reduced GHG emissions.
DOE also estimated the monetary value of the health benefits
associated with NOX and SO2 emissions reductions
anticipated to result from the considered TSLs for consumer
conventional cooking products. The dollar-per-ton values that DOE used
are discussed in section IV.L of this document. Table V.50 presents the
present value for NOX emissions reduction for each TSL
calculated using 7-percent and 3-percent discount rates, and Table V.51
presents similar results for SO2 emissions reductions. The
results in these tables reflect application
[[Page 6889]]
of EPA's low dollar-per-ton values, which DOE used to be conservative.
The time-series of annual values is presented for the proposed TSL in
chapter 14 of the TSD for this SNOPR.

DOE has not considered the monetary benefits of the reduction of Hg
for this proposed rule. DOE has also not quantitatively assessed the
health benefits of reducing in-home exposure to particulate matter,
nitrogen dioxide, and other hazardous air pollutants. Such in-home
emissions may be associated with a variety of serious respiratory and
cardiovascular conditions and other health risks. Not all the public
health and environmental benefits from the reduction of greenhouse
gases, NOX, and SO2 are captured in the values
above, and additional unquantified benefits from the reductions of
those pollutants as well as from the reduction of Hg, direct PM, and
other co-pollutants may be significant. For example, studies have
indicated that gas ranges, particularly when used without venting
systems, can expose household members to indoor air pollution at levels
that exceed health-based guidelines.
DOE seeks comment on any impacts of its proposals in this SNOPR on
indoor air pollutants released by gas cooking products, as well as any
other design approaches, control strategies, or other measures to
mitigate these emissions.
7. Other Factors
The Secretary of Energy, in determining whether a standard is
economically justified, may consider any other factors that the
Secretary deems to be relevant. (42 U.S.C. 6295(o)(2)(B)(i)(VII)) No
other factors were considered in this analysis.
8. Summary of Economic Impacts
Table V.52 presents the NPV values that result from adding the
estimates of the potential economic benefits resulting from reduced
GHG, NOX and SO2 emissions to the NPV of consumer
benefits calculated for each TSL considered in this rulemaking. The
consumer benefits are domestic U.S. monetary savings that occur as a
result of purchasing the covered products, and are measured for the
lifetime of products shipped in 2027-2056. The climate benefits
associated with reduced GHG emissions resulting from the adopted
standards are global benefits and are also calculated based on the
lifetime of consumer conventional cooking products shipped in 2027-
2056.

C. Conclusion
When considering new or amended energy conservation standards, the
standards that DOE adopts for any type (or class) of covered product
must be designed to achieve the maximum improvement in energy
efficiency that the Secretary determines is technologically feasible
and economically justified. (42 U.S.C. 6295(o)(2)(A)) In determining
whether a standard is economically justified, the Secretary must
determine whether the benefits of the standard exceed its burdens by,
to the greatest extent practicable, considering the seven statutory
factors discussed previously. (42 U.S.C. 6295(o)(2)(B)(i)) The new or
amended standard must also result in significant conservation of
energy. (42 U.S.C. 6295(o)(3)(B))
For this SNOPR, DOE considered the impacts of new and amended
standards for consumer conventional cooking products at each TSL,
beginning with the maximum technologically feasible level, to determine
whether that level was economically justified. Where the max-tech level
was not justified, DOE then considered the next most efficient level
and undertook the same evaluation until it reached the highest
efficiency level that is both technologically feasible and economically
justified and saves a significant amount of energy. DOE refers to this
process at the ``walk-down'' analysis.
To aid the reader as DOE discusses the benefits and/or burdens of
each TSL, tables in this section present a summary of the results of
DOE's quantitative analysis for each TSL. In addition to the
quantitative results presented in the tables, DOE also considers other
burdens and benefits that affect economic justification. These include
the impacts on identifiable subgroups of consumers who may be
disproportionately affected by a national standard and impacts on
employment.
DOE also notes that the economics literature provides a wide-
ranging discussion of how consumers trade off upfront costs and energy
savings in the absence of government intervention. Much of this
literature attempts to explain why consumers appear to undervalue
energy efficiency improvements. There is evidence that consumers
undervalue future energy savings as a result of (1) a lack of
information or informational asymmetries, (2) a lack of sufficient
salience of the long-term or aggregate benefits, (3) a lack of
sufficient personal financial savings to warrant delaying or altering
purchases, (4) excessive focus on the short term, in the form of
inconsistent weighting of future energy cost savings relative to
available returns on other investments, due to loss aversion, myopia,
inattention, or other factors, (5) computational or other difficulties
associated with the evaluation of relevant tradeoffs, and (6) a
divergence in incentives (for example, between renters and owners, or
builders and purchasers, or between current and subsequent owners).
Having less than perfect foresight and a high degree of uncertainty
about the future, consumers may trade off these types of investments at
a higher-than-expected rate between current consumption and uncertain
future energy cost savings.
In DOE's current regulatory analysis, potential changes in the
benefits and costs of a regulation due to changes in consumer purchase
decisions are included in two ways. First, if consumers forego the
purchase of a product in the standards case, this decreases sales for
product manufacturers, and the impact on manufacturers attributed to
lost revenue is included in the MIA. Second, DOE accounts for energy
savings attributable only to products actually used by consumers in the
standards case; if a standard decreases the number of products
purchased by consumers, this decreases the potential energy savings
from an energy conservation standard. DOE provides estimates of
shipments and changes in the volume of product purchases in chapter 9
of the TSD for this SNOPR. However, DOE's current analysis does not
explicitly control for heterogeneity in consumer preferences,
preferences across subcategories of products or specific features, or
consumer price sensitivity variation according to household
income.\116\

While DOE is not prepared at present to provide a fuller
quantifiable framework for estimating the benefits and costs of changes
in consumer purchase decisions due to an energy conservation standard,
DOE is committed to developing a framework that can support empirical
quantitative tools for improved assessment of the consumer welfare
impacts of appliance standards. DOE has posted a paper that discusses
the issue of consumer welfare impacts of appliance energy conservation
standards, and potential enhancements to the methodology by which these
impacts are defined and estimated in the regulatory process.\117\

standards on consumer choice and how to quantify this impact in its
regulatory analysis in future rulemakings.
1. Benefits and Burdens of TSLs Considered for Consumer Conventional
Cooking Products Standards
Table V.53 and Table V.54 summarize the quantitative impacts
estimated for each TSL for consumer conventional cooking products. The
national impacts are measured over the lifetime of consumer
conventional cooking products purchased in the 30-year period that
begins in the anticipated year of compliance with amended standards
(2027-2056). The energy savings, emissions reductions, and value of
emissions reductions refer to full-fuel-cycle results. DOE is
presenting monetized benefits in accordance with the applicable
Executive Orders and DOE would reach the same conclusion presented in
this notice in the absence of the social cost of greenhouse gases,
including the Interim Estimates presented by the Interagency Working
Group. The efficiency levels contained in each TSL are described in
section V.A of this document.

Note: This table presents the costs and benefits associated with consumer conventional cooking products shipped
in 2027-2056. These results include benefits to consumers which accrue after 2056 from the products shipped in
2027-2056.
* Climate benefits are calculated using four different estimates of the SC-CO2, SC-CH4 and SC-N2O. Together,
these represent the global SC-GHG. For presentational purposes of this table, the climate benefits associated
with the average SC-GHG at a 3 percent discount rate are shown, but the Department does not have a single
central SC-GHG point estimate. On March 16, 2022, the Fifth Circuit Court of Appeals (No. 22-30087) granted
the Federal government's emergency motion for stay pending appeal of the February 11, 2022, preliminary
injunction issued in Louisiana v. Biden, No. 21-cv-1074-JDC-KK (W.D. La.). As a result of the Fifth Circuit's
order, the preliminary injunction is no longer in effect, pending resolution of the Federal government's
appeal of that injunction or a further court order. Among other things, the preliminary injunction enjoined
the defendants in that case from ``adopting, employing, treating as binding, or relying upon'' the interim
estimates of the social cost of greenhouse gases--which were issued by the Interagency Working Group on the
Social Cost of Greenhouse Gases on February 26, 2021--to monetize the benefits of reducing greenhouse gas
emissions. As reflected in this rule, DOE has reverted to its approach prior to the injunction and presents
monetized benefits where appropriate and permissible under law.
** Health benefits are calculated using benefit-per-ton values for NOX and SO2. DOE is currently only monetizing
(for NOX and SO2) PM2.5 precursor health benefits and (for NOX) ozone precursor health benefits, but will
continue to assess the ability to monetize other effects such as health benefits from reductions in direct
PM2.5 emissions. The health benefits are presented at real discount rates of 3 and 7 percent. See section IV.L
of this document for more details.
*** Negative values denoted in parentheses.
[dagger] Total and net benefits include consumer, climate, and health benefits. For presentation purposes, total
and net benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with 3-
percent discount rate, but the Department does not have a single central SC-GHG point estimate. DOE emphasizes
the importance and value of considering the benefits calculated using all four sets of SC-GHG estimates.
[Dagger] Costs include incremental equipment costs as well as installation costs.

DOE first considered TSL 3, which represents the max-tech
efficiency levels for all product classes except for electric open
(coil) element cooking tops, for which the only considered efficiency
level is the baseline. TSL 3 would save an estimated 1.47 quads of
energy, an amount DOE considers significant. Under TSL 3, the NPV of
consumer benefit would decrease compared to the no-new-standards case
by $15.68 billion using a discount rate of 7 percent, and by $27.75
billion using a discount rate of 3 percent.
The cumulative emissions reductions at TSL 3 are 55.5 Mt of
CO2, 16.7 thousand tons of SO2, 105.0 thousand
tons of NOX, 0.11 tons of Hg, 482.2 thousand tons of
CH4, and 0.4 thousand tons of N2O. The estimated
monetary value of the climate benefits from reduced GHG emissions
(associated with the average SC-GHG at a 3-percent discount rate) at
TSL 3 is $2.77 billion. The estimated monetary value of the health
benefits from reduced SO2 and NOX emissions at
TSL 3 is $1.62 billion using a 7-percent discount rate and $4.33
billion using a 3-percent discount rate.
Using a 7-percent discount rate for consumer benefits and costs,
health benefits from reduced SO2 and NOX
emissions, and the 3-percent discount rate case for climate benefits
from reduced GHG emissions, the estimated total NPV at TSL 3 is $11.29
billion less than the no-new-standards case. Using a 3-percent discount
rate for all benefits and costs, the estimated total NPV at TSL 3 is
$20.65 billion less than the no-new-standards case. The estimated total
NPV is provided for additional information. However, DOE primarily
relies upon the NPV of consumer benefits when determining whether a
proposed standard level is economically justified.
At TSL 3, the average LCC impact is a savings of $22 for gas
cooking tops and an average LCC loss of $580 for electric smooth
element cooking tops, $30 for freestanding electric standard ovens, $33
for built-in/slide-in electric standard ovens, $15 for freestanding
electric self-clean ovens, $11 for built-in/slide-in electric self-
clean ovens, $8 for freestanding gas standard ovens, $13 for built-in/
slide-in gas standard ovens, $1 for freestanding gas self-clean ovens,
and $5 for built-in/slide-in gas self-clean ovens. The simple payback
period is 87.5 years for electric smooth element cooking tops, 5.0
years for gas cooking tops, 17.0 years for freestanding electric ovens,
17.2 years for built-in/slide-in electric ovens, 14.1 years for
freestanding gas ovens, and 14.4 years for built-in/slide-in gas ovens.
The fraction of consumers experiencing a net LCC cost is 95 percent for
electric smooth element cooking tops, 18 percent for gas cooking tops,
80 percent for freestanding electric standard ovens, 81 percent for
built-in/slide-in electric standard ovens, 75 percent for freestanding
electric self-clean ovens, 72 percent for built-in/slide-in electric
self-clean ovens, 33 percent for freestanding gas standard ovens, 56
percent for built-in/slide-in gas standard ovens, 6 percent for
freestanding gas self-clean ovens, and 20 percent for built-in/slide-in
gas self-clean ovens. At TSL 3, the proposed standard for electric open
(coil) element cooking tops is at the baseline resulting in no LCC
impact, an undefined PBP, and no consumers experiencing a net LCC cost.
At TSL 3, the projected change in INPV ranges from a decrease of
$1,368.6 million to a decrease of $1,185.1 million, which corresponds
to decreases of 85.2 percent and 73.8 percent, respectively. DOE
estimates that industry must invest $1,846.4 million to comply with
standards set at TSL 3. DOE estimates that 100 percent of the electric
open (coil) element cooking top shipments, 5 percent of the electric
smooth element cooking top shipments, 4 percent of the gas cooking top
shipments, zero percent of the electric standard oven (freestanding and
built-in) shipments, zero percent of the electric self-clean oven
(freestanding) shipments, 2 percent of the electric self-clean (built-
in) shipments, 62 percent of gas standard oven (freestanding)
shipments, 38 percent of the gas standard oven (built-in) shipments, 93
percent of the gas self-clean oven (freestanding) shipments, and 77
percent of the gas self-clean (built-in) shipments would already meet
the efficiency levels required at TSL 3 in 2027.
[[Page 6893]]
The Secretary tentatively concludes that at TSL 3 for consumer
conventional cooking products, the benefits of energy savings, emission
reductions, and the estimated monetary value of the emissions
reductions would be outweighed by the negative NPV of consumer
benefits, the economic burden on many consumers (e.g., negative LCC
savings across all product classes except gas cooking tops), and the
significant impacts on manufacturers, including the large conversion
costs and the significant reduction in INPV. A significant fraction of
electric smooth element cooking top, electric oven, and gas standard
oven consumers would experience a net LCC cost and negative LCC
savings. The consumer NPV is negative at both 3 and 7 percent. The
potential reduction in INPV could be as high as 85.2 percent.
Consequently, the Secretary has tentatively concluded that TSL 3 is not
economically justified as a whole, and in particular for all product
classes except for gas cooking tops. DOE notes that for gas cooking
tops, the only product class with positive LCC savings, the same EL (2)
is carried forward to TSL 2.
DOE then considered TSL 2, which represents the baseline efficiency
for electric open (coil) element cooking tops, efficiency level 1 for
electric smooth element cooking tops, electric ovens, and gas ovens,
and efficiency level 2 for gas cooking tops. TSL 2 would save an
estimated 0.46 quads of energy, an amount DOE considers significant.
Under TSL 2, the NPV of consumer benefit would be $0.65 billion using a
discount rate of 7 percent, and $1.71 billion using a discount rate of
3 percent.
The cumulative emissions reductions at TSL 2 are 21.9 Mt of
CO2, 2.2 thousand tons of SO2, 51.8 thousand tons
of NOX, 0.01 tons of Hg, 244.9 thousand tons of
CH4, and 0.1 thousand tons of N2O. The estimated
monetary value of the climate benefits from reduced GHG emissions
(associated with the average SC-GHG at a 3-percent discount rate) at
TSL 2 is $1.17 billion. The estimated monetary value of the health
benefits from reduced SO2 and NOX emissions at
TSL 2 is $0.61 billion using a 7-percent discount rate and $1.63
billion using a 3-percent discount rate.
Using a 7-percent discount rate for consumer benefits and costs,
health benefits from reduced SO2 and NOX
emissions, and the 3-percent discount rate case for climate benefits
from reduced GHG emissions, the estimated total NPV at TSL 2 is $2.43
billion. Using a 3-percent discount rate for all benefits and costs,
the estimated total NPV at TSL 2 is $4.51 billion. The estimated total
NPV is provided for additional information, however DOE primarily
relies upon the NPV of consumer benefits when determining whether a
proposed standard level is economically justified.
At TSL 2, the average LCC impact is a savings of $13 for electric
smooth element cooking tops, $22 for gas cooking tops, $1 for electric
ovens, and $1 for gas ovens. The simple payback period is 0.6 years for
electric smooth element cooking tops, 5.0 years for gas cooking tops,
1.7 years for freestanding electric ovens, 1.8 years for built-in/
slide-in electric ovens, 1.9 years for freestanding gas ovens, and 2.0
years for built-in/slide-in gas ovens. The fraction of consumers that
experience a net LCC cost is 0 percent for electric smooth element
cooking tops, 18 percent for gas cooking tops, 0 percent for electric
ovens, and 1 percent for gas ovens. At TSL 2, the proposed standard for
electric open (coil) element cooking tops is at the baseline resulting
in no LCC impact, an undefined PBP, and no consumers experiencing a net
LCC cost.
At TSL 2, the projected change in INPV ranges from a decrease of
$154.8 million to a decrease of $150.4 million, which correspond to
decreases of 9.6 percent and 9.4 percent, respectively. DOE estimates
that industry must invest $183.4 million to comply with standards set
at TSL 2. DOE estimates that 100 percent of the electric open (coil)
element cooking top shipments, 80 percent of the electric smooth
element cooking top shipments, 4 percent of the gas cooking top
shipments, 95 percent of the electric oven shipments, and 96 percent of
the gas oven shipments would already meet or exceed the efficiency
levels required at TSL 2 in 2027.
After considering the analysis and weighing the benefits and
burdens, the Secretary has tentatively concluded that at a standard set
at TSL 2 for consumer conventional cooking products would be
economically justified for all product classes. At this TSL, the
average LCC savings for all conventional cooking product classes is
positive. A shipment-weighted 4 percent of conventional cooking product
consumers experience a net cost, with the highest in any single product
class being 18 percent for gas cooking tops; the percent net cost for
all other product classes is between 0 to 1 percent. The FFC national
energy savings are significant and the NPV of consumer benefits is
positive using both a 3-percent and 7-percent discount rate. Notably,
the benefits to consumers vastly outweigh the cost to manufacturers. At
TSL 2, the NPV of consumer benefits, even measured at the more
conservative discount rate of 7 percent is over 4 times higher than the
maximum estimated manufacturers' loss in INPV. The standard levels at
TSL 2 are economically justified even without weighing the estimated
monetary value of emissions reductions. When those emissions reductions
are included--representing $1.17 billion in climate benefits
(associated with the average SC-GHG at a 3-percent discount rate), and
$1.63 billion (using a 3-percent discount rate) or $0.61 billion (using
a 7-percent discount rate) in health benefits--the rationale becomes
stronger still.
As stated, DOE conducts the walk-down analysis to determine the TSL
that represents the maximum improvement in energy efficiency that is
technologically feasible and economically justified as required under
EPCA. The walk-down is not a comparative analysis, as a comparative
analysis would result in the maximization of net benefits instead of
energy savings that are technologically feasible and economically
justified, which would be contrary to the statute. 86 FR 70892, 70908.
Although DOE has not conducted a comparative analysis to select the
proposed energy conservation standards, DOE notes that TSL 2 has a
lower percentage of consumers experiencing a net cost and a shorter
payback period relative to TSL 3.
Although DOE considered proposed amended standard levels for
conventional cooking products by grouping the efficiency levels for
each product class into TSLs, DOE evaluates all analyzed efficiency
levels in its analysis. For electric open (coil) element cooking tops,
TSL 2 represents the baseline efficiency level, the only level
considered in this product class in this SNOPR. For electric smooth
element cooking tops, TSL 2 represents EL 1 which incorporates low-
standby-loss electronic controls. Setting a standard at EL 2 or EL 3
would result in a larger percentage of consumers experiencing a net LCC
cost and longer payback periods relative to EL 1. For gas cooking tops,
TSL 2 represents EL 2, the maximum measured efficiency for products
with at least one HIR burner, which is determined to be technologically
feasible and economically justified. For electric and gas ovens, TSL 2
corresponds to EL 1, which incorporates switch mode power supplies. A
standard at EL 2 or EL 3 for electric ovens would result in a
significantly higher percentage of consumers experiencing a net LCC
cost and longer payback periods relative to EL 1. Similarly, for gas
ovens, a
[[Page 6894]]
standard at EL 2 would result in a larger percentage of consumers
experiencing a net LCC cost and longer payback periods relative to EL
1. The proposed standard levels at TSL 2 results in positive LCC
savings for all product classes and a lower percentage of consumers
experiencing a net cost to the point where DOE has tentatively
concluded that they are economically justified, as discussed for TSL 2
in the preceding paragraphs.
Therefore, based on the above considerations, DOE proposes to adopt
the energy conservation standards for consumer conventional cooking
products at TSL 2. The proposed amended energy conservation standards
for consumer conventional cooking products, are shown in Table V.55 and
Table V.56.

2. Annualized Benefits and Costs of the Proposed Standards
The benefits and costs of the proposed standards can also be
expressed in terms of annualized values. The annualized net benefit is
(1) the annualized national economic value (expressed in 2021$) of the
benefits from operating products that meet the proposed standards
(consisting primarily of operating cost savings from using less energy,
minus increases in product purchase costs, and (2) the annualized
monetary value of the climate and health benefits from emission
reductions.
Table V.57 shows the annualized values for consumer conventional
cooking products under TSL 2, expressed in 2021$. The results under the
primary estimate are as follows.
Using a 7-percent discount rate for consumer benefits and costs and
NOX and SO2 reduction benefits, and a 3-percent
discount rate case for GHG social costs, the estimated cost of the
proposed standards for consumer conventional cooking products is $32.5
million per year in increased equipment costs, while the estimated
annual benefits are $100.8 million from reduced equipment operating
costs, $67.0 million from GHG reductions, and $64.9 million from
reduced NOX and SO2 emissions. In this case, the
net benefit amounts to $200.3 million per year.
Using a 3-percent discount rate for all benefits and costs, the
estimated cost of the proposed standards for consumer conventional
cooking products is $32.2 million per year in increased equipment
costs, while the estimated annual benefits are $130.7 million in
reduced operating costs, $67.0 million from GHG reductions, and $93.8
million from reduced NOX and SO2 emissions. In
this case, the net benefit amounts to $259.2 million per year.

Note: This table presents the costs and benefits associated with consumer conventional cooking products shipped
in 2027-2056. These results include benefits to consumers which accrue after 2056 from the products shipped in
2027-2056. The Primary, Low Net Benefits, and High Net Benefits Estimates utilize projections of energy prices
from the AEO2022 Reference case, Low Economic Growth case, and High Economic Growth case, respectively. In
addition, incremental equipment costs reflect a medium decline rate in the Primary Estimate, a low decline
rate in the Low Net Benefits Estimate, and a high decline rate in the High Net Benefits Estimate. The methods
used to derive projected price trends are explained in sections IV.F.1 and IV.H.3 of this document. Note that
the Benefits and Costs may not sum to the Net Benefits due to rounding.
* Climate benefits are calculated using four different estimates of the global SC-GHG (see section IV.L of this
document). For presentational purposes of this table, the climate benefits associated with the average SC-GHG
at a 3 percent discount rate are shown, but the Department does not have a single central SC-GHG point
estimate, and it emphasizes the importance and value of considering the benefits calculated using all four SC-
GHG estimates. On March 16, 2022, the Fifth Circuit Court of Appeals (No. 22-30087) granted the Federal
government's emergency motion for stay pending appeal of the February 11, 2022, preliminary injunction issued
in Louisiana v. Biden, No. 21-cv-1074-JDC-KK (W.D. La.). As a result of the Fifth Circuit's order, the
preliminary injunction is no longer in effect, pending resolution of the Federal government's appeal of that
injunction or a further court order. Among other things, the preliminary injunction enjoined the defendants in
that case from ``adopting, employing, treating as binding, or relying upon'' the interim estimates of the
social cost of greenhouse gases--which were issued by the Interagency Working Group on the Social Cost of
Greenhouse Gases on February 26, 2021--to monetize the benefits of reducing greenhouse gas emissions. As
reflected in this rule, DOE has reverted to its approach prior to the injunction and presents monetized
benefits where appropriate and permissible under law.
** Health benefits are calculated using benefit-per-ton values for NOX and SO2. DOE is currently only monetizing
(for SO2 and NOX) PM2.5 and (for NOX) ozone precursor health benefits, but will continue to assess the ability
to monetize other effects such as health benefits from reductions in direct PM2.5 emissions. The health
benefits are presented at real discount rates of 3 and 7 percent. See section IV.L of this document for more
details.
[dagger] Total benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with 3-
percent discount rate, but the Department does not have a single central SC-GHG point estimate.
[Dagger] Costs include incremental equipment costs as well as installation costs.
D. Reporting, Certification, and Sampling Plan
Manufacturers, including importers, must use product-specific
certification templates to certify compliance to DOE. For consumer
conventional cooking products, the certification template reflects the
general certification requirements specified at 10 CFR 429.12 and the
product-specific requirements specified at 10 CFR 429.23.
In manufacturer interviews, multiple manufacturers expressed
concern about the variability of cooking top test results and the
potential impact on certifying compliance, but none provided
information regarding how DOE should consider such variability in its
analysis of potential energy conservation standards for cooking tops.
DOE notes that as part of the August 2022 TP Final Rule, a sampling
plan for cooking tops was established at 10 CFR 429.23, requiring that
a sample of sufficient size be tested to ensure that any represented
value of IAEC be greater than the mean of the sample or than the upper
97.5 percent confidence limit of the true mean divided by 1.05. DOE is
not proposing to amend the product-specific certification requirements
for these products in this SNOPR because it does not have information
regarding whether the confidence limit should be adjusted.
DOE seeks comment and data to potentially re-evaluate the sampling
plan for cooking tops in the context of any potential performance
standards for these products.
VI. Procedural Issues and Regulatory Review
A. Review Under Executive Orders 12866 and 13563
Executive Order (``E.O.'') 12866, ``Regulatory Planning and
Review,'' as supplemented and reaffirmed by E.O. 13563, ``Improving
Regulation and Regulatory Review,'' 76 FR 3821 (Jan. 21, 2011),
requires agencies, to the extent permitted by law, to (1) propose or
adopt a regulation only upon a reasoned determination that its benefits
justify its costs (recognizing that some benefits and costs are
difficult to quantify); (2) tailor regulations to impose the least
burden on society, consistent with obtaining regulatory objectives,
taking into account, among other things, and to the extent practicable,
the costs of cumulative regulations; (3) select, in choosing among
alternative regulatory approaches, those approaches that maximize net
benefits (including potential economic, environmental, public health
and safety, and other advantages; distributive impacts; and equity);
(4) to the extent feasible, specify performance objectives, rather than
specifying the behavior or manner of compliance that regulated entities
must adopt; and (5) identify and assess available alternatives to
direct regulation, including providing economic incentives to encourage
the desired behavior, such as user fees or marketable permits, or
providing information upon which choices can be made by the public. DOE
emphasizes as well that E.O. 13563 requires agencies to use the best
available techniques to quantify anticipated present and future
benefits and costs as accurately as possible. In its guidance, the
Office of Information and Regulatory Affairs (``OIRA'') in OMB has
emphasized that such techniques may include identifying changing future
compliance costs that might result from
[[Page 6896]]
technological innovation or anticipated behavioral changes. For the
reasons stated in the preamble, this proposed regulatory action is
consistent with these principles.
Section 6(a) of E.O. 12866 also requires agencies to submit
``significant regulatory actions'' to OIRA for review. OIRA has
determined that this proposed regulatory action constitutes a
``significant regulatory action within the scope of section 3(f)(1)''
of E.O. 12866. Accordingly, pursuant to section 6(a)(3)(C) of E.O.
12866, DOE has provided to OIRA an assessment, including the underlying
analysis, of benefits and costs anticipated from the proposed
regulatory action, together with, to the extent feasible, a
quantification of those costs; and an assessment, including the
underlying analysis, of costs and benefits of potentially effective and
reasonably feasible alternatives to the planned regulation, and an
explanation why the planned regulatory action is preferable to the
identified potential alternatives. These assessments are summarized in
this preamble and further detail can be found in the technical support
document for this rulemaking.
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of an initial regulatory flexibility analysis (``IRFA'')
for any rule that by law must be proposed for public comment, unless
the agency certifies that the rule, if promulgated, will not have a
significant economic impact on a substantial number of small entities.
As required by E.O. 13272, ``Proper Consideration of Small Entities in
Agency Rulemaking,'' 67 FR 53461 (Aug. 16, 2002), DOE published
procedures and policies on February 19, 2003, to ensure that the
potential impacts of its rules on small entities are properly
considered during the rulemaking process. 68 FR 7990. DOE has made its
procedures and policies available on the Office of the General
Counsel's website (energy.gov/gc/office-general-counsel). DOE has
prepared the following IRFA for the products that are the subject of
this rulemaking.
For manufacturers of consumer conventional cooking products, the
SBA has set a size threshold, which defines those entities classified
as ``small businesses'' for the purposes of the statute. DOE used the
SBA's small business size standards to determine whether any small
entities would be subject to the requirements of the rule. (See 13 CFR
part 121.) The size standards are listed by North American Industry
Classification System (``NAICS'') code and industry description and are
available at www.sba.gov/document/support--table-size-standards.
Manufacturing of consumer conventional cooking products is classified
under NAICS 335220, ``Major Household Appliance Manufacturing.'' The
SBA sets a threshold of 1,500 employees or fewer for an entity to be
considered as a small business for this category.
1. Description of Reasons Why Action Is Being Considered
EPCA prescribed energy conservation standards for consumer
conventional cooking products (42 U.S.C. 6295(h)(1)), and directs DOE
to conduct future rulemakings to determine whether to amend these
standards. (42 U.S.C. 6295(h)(2)) EPCA further provides that, not later
than 6 years after the issuance of any final rule establishing or
amending a standard, DOE must publish either a notice of determination
that standards for the product do not need to be amended, or a NOPR
including new proposed energy conservation standards (proceeding to a
final rule, as appropriate). (42 U.S.C. 6295(m)(1)) This rulemaking is
in accordance with DOE's obligations under EPCA.
2. Objectives of, and Legal Basis for, Rule
NAECA, Public Law 100-12, amended EPCA to establish prescriptive
standards for gas cooking products, requiring gas ranges and ovens with
an electrical supply cord that are manufactured on or after January 1,
1990, not to be equipped with a constant burning pilot light. (42
U.S.C.6295(h)(1)) NAECA also directed DOE to conduct two cycles of
rulemakings to determine if more stringent or additional standards were
justified for kitchen ranges and ovens. (42 U.S.C. 6295(h)(2)) EPCA
additionally requires that, not later than 6 years after the issuance
of a final rule establishing or amending a standard, DOE publish a NOPR
proposing new standards or a notification of determination that the
existing standards do not need to be amended. (42 U.S.C. 6295(m)(1))
This rulemaking is also in accordance with the six-year review required
under 42 U.S.C. 6295(m)(1).
3. Description of Estimated Number of Small Entities Regulated
DOE has recently conducted a focused inquiry into small business
manufacturers of the products covered by this rulemaking. DOE used the
SBA's small business size standards to determine whether any small
entities would be subject to the requirements of the rule. The size
standards are listed by NAICS code as well as by industry description
and are available at www.sba.gov/document/support--table-size-
standards. Manufacturing cooking tops is classified under NAICS 335220,
``major household appliance manufacturing.'' The SBA sets a threshold
of 1,500 employees or fewer for an entity to be considered as a small
business for this category. DOE used available public information to
identify potential small manufacturers. DOE accessed the Compliance
Certification Database \118\ (CCD), the Modernized Appliance Efficiency
Database System \119\ (MAEDbS), and the National Resources Canada
database \120\ (NRCan) to create a list of companies that import or
otherwise manufacture the products covered by this SNOPR. Additionally,
in response to the September 2016 SNOPR, Felix Storch provided a list
of potential small businesses, not previously identified in the
September 2016 SNOPR.\121\ (Felix Storch, No. 62 at p. 2) Once DOE
created a list of potential manufacturers, DOE used market research
tools to determine whether any companies met SBA's definition of a
small entity--based on the total number of employees for each company
including parent, subsidiary, and sister entities--and gather annual
revenue estimates.

\121\ Some of the companies Felix Storch identified, either had
more than 1,500 employees, were completely foreign owned and
operated, or did not sell any products covered by this rulemaking.
Therefore, these companies do not meet SBA's definition of a small
business and DOE did not include these companies in this IRFA. The
remaining companies that do meet SBA's definition of a small
business were included in this IRFA.
---------------------------------------------------------------------------
Based on DOE's analysis, DOE identified 34 companies potentially
manufacturing consumer conventional cooking products covered by this
rulemaking. DOE screened out companies that have more than 1,500 total
employees or are entirely foreign owned and operated, and therefore do
not meet SBA's requirements to be considered a small entity. Of the 34
companies DOE identified as manufacturing consumer conventional cooking
products sold in the United States, 15 were identified as potential
small businesses.
[[Page 6897]]
4. Description and Estimate of Compliance Requirements Including
Differences in Cost, if Any, for Different Groups of Small Entities
DOE is proposing TSL 2 in this SNOPR. For all oven product classes,
TSL 2 requires that the ovens not be equipped with a linear power
supply. Based on DOE's shipment analysis more than 95 percent of ovens
use a switch mode power supply and therefore are not equipped with a
linear power supply. Based on DOE's shipment analysis, DOE assumed
most, if not all, small businesses already use switch mode power
supplies for the ovens they manufacturer. If any small businesses do
still use linear power supplies in their ovens, there would be minimal
conversion costs to these small businesses, as switch mode power
supplies can be purchased as a separate component and would most likely
not require a significant redesign to incorporate these switch mode
power supplies. The remainder of this cost analysis focuses on the
costs associated with complying with the proposed cooking top energy
conservation standards.
As stated in the previous section, DOE identified 15 potential
small manufacturers of consumer conventional cooking products. All 15
of these small businesses manufacture cooking tops. These 15 small
businesses can be grouped into two manufacturing groups: those that
manufacture entry level cooking tops and those that manufacture premium
cooking tops.
Gas cooking top entry level products typically have thinner non-
continuous grates with only one burner above 14,000 BTUs (although some
of these small businesses may offer a limited number of models with
thicker continuous grates and more than one burner above 14,000 BTUs).
Electric cooking top entry level products typically have electric coil
element cooking tops (although a few small businesses may have up to 25
percent of their electric ranges or electric cooking tops using
electric smooth element cooking tops). These entry level small
businesses usually compete on price in the market.
Gas cooking top premium products typically have thicker continuous
grates with multiple burners above 14,000 BTUs. Electric cooking top
premium products use smooth element, typically with induction
technology. Small businesses manufacturing premium products do not
offer electric coil element cooking tops. Lastly, small businesses
manufacturing premium products typically compete on the high quality
and professional look and design of their products. These ranges or
cooking tops are typically significantly more expensive than entry
level products.
Based on data from each small business's websites, DOE estimated
the number of basic models each small business offers.

DOE estimated the small business conversion costs and testing costs
using the same methodology used to estimate the industry conversion
costs, described in section IV.J.2.c of this document. There are two
types of conversion costs that small businesses could incur due to the
proposed standards: product conversion costs (including any testing
costs) and capital conversion costs. Felix Storch commented in response
to the September 2016 SNOPR that small manufacturers often lack the
staff with expertise to fully understand the test procedures,
complexities and nuances of the regulations. (Felix Storch, No. 62 at
p. 2) Additionally, Felix Storch commented that small manufacturers pay
substantially more and have longer lead times for energy testing.
(Felix Storch, No. 62 at p. 3) In the August 2022 TP Final Rule, DOE
estimated a lower per unit testing costs for testing done in-house and
a more costly third-party lab per unit testing cost. For this IRFA, DOE
assumed all small businesses would incur the more costly third-party
lab per unit testing cost, as most small businesses do not have in-
house testing capabilities or capacity to test all their products in
accordance with the DOE test procedure.
Product conversion costs are investments in R&D, testing,
marketing, and other non-capitalized costs necessary to make product
designs comply with new and amended energy conservation standards.
Capital conversion costs are investments in property, plant, and
equipment necessary to adapt or change existing production facilities
such that new compliant product designs can be fabricated and
assembled. Manufacturers would have to incur testing costs for all
cooking tops since DOE is proposing to establish a new energy
conservation standard for cooking tops. Therefore, even products that
meet the proposed energy conservation standard would incur testing
costs to test these cooking tops to demonstrate compliance with the
proposed energy conservation
[[Page 6898]]
standards. However, manufacturers would only incur R&D product
conversion costs and capital conversion costs if they have products
that do not meet the energy conservation standards.
Based on the estimated model counts for each cooking top product
class shown in Table VI.2 and the conversion cost and testing cost
methodology used to calculate industry conversion costs, DOE estimated
the conversion costs and testing costs for each small business,
displayed in Table VI.3. DOE then used D&B Hoovers \122\ to estimate
the annual revenue for each small business. Manufacturers will have 3
years between publication of a final rule and compliance with the
energy conservation standards. Therefore, DOE presents the estimated
conversion costs and testing costs as a percent of the estimated 3
years of annual revenue for each small business.

Based on Table VI.3 there are two premium small businesses
manufacturers that could be significantly impacted by this proposed
rulemaking, if finalized as proposed.
DOE requests comment on its findings that there are 15 domestic
small businesses that manufacture conventional cooking products and its
estimate of the potential impacts on these small businesses.
Additionally, DOE requests comment on the potential for any small
businesses to exit the consumer conventional cooking products market in
response to the proposed energy conservation standards.
5. Duplication, Overlap, and Conflict With Other Rules and Regulations
DOE is not aware of any rules or regulations that duplicate,
overlap, or conflict with the rule being considered.
6. Significant Alternatives to the Rule
The discussion in the previous section analyzes impacts on small
businesses that would result from DOE's proposed rule, represented by
TSL 2. In reviewing alternatives to the proposed rule, DOE examined
energy conservation standards set at lower efficiency levels. DOE
estimates that manufacturers, including small businesses, would have to
spend approximately 43 percent less conversion costs at TSL 1 compared
to TSL 2. While TSL 1 would reduce the impacts on small business
manufacturers, it would come at the expense of a reduction in energy
savings and consumer savings. TSL 1 achieves 39 percent lower energy
savings compared to the energy savings at TSL 2. Additionally, TSL 1
achieves 44 percent lower consumer NPV at 3 percent and 49 percent
lower consumer NPV at 7 percent compared to the consumer NPV achieved
at TSL 2.
Based on the presented discussion, establishing standards at TSL 2
balances the benefits of the energy savings at TSL 2 with the potential
burdens placed on consumer conventional cooking product manufacturers,
including small business manufacturers. Accordingly, DOE does not
propose one of the other TSLs considered in the analysis, or the other
policy alternatives examined as part of the regulatory impact analysis
and included in chapter 17 of the TSD for this SNOPR.
DOE seeks comment on the policy alternatives presented in the
regulatory impact analysis and data that can be used to estimate the
manufacturer response to Federal credits.
Additional compliance flexibilities may be available through other
means. EPCA provides that a manufacturer whose annual gross revenue
from all of its operations does not exceed $8 million may apply for an
exemption from all or part of an energy conservation standard for a
period not longer than 24 months after the effective date of a final
rule establishing the standard. (42 U.S.C. 6295(t)) Additionally,
manufacturers subject to DOE's energy efficiency standards may apply to
DOE's Office of Hearings and Appeals for exception relief under certain
circumstances. Manufacturers should refer to 10 CFR part 430, subpart
E, and 10 CFR part 1003 for additional details.
C. Review Under the Paperwork Reduction Act
Under the procedures established by the Paperwork Reduction Act of
1995 (``PRA''), a person is not required to respond to a collection of
information by a Federal agency unless that
[[Page 6899]]
collection of information displays a currently valid OMB Control
Number.
OMB Control Number 1910-1400, Compliance Statement Energy/Water
Conservation Standards for Appliances, is currently valid and assigned
to the certification reporting requirements applicable to covered
equipment, including consumer conventional cooking products.
DOE's certification and compliance activities ensure accurate and
comprehensive information about the energy and water use
characteristics of covered products and covered equipment sold in the
United States. Manufacturers of all covered products and covered
equipment must submit a certification report before a basic model is
distributed in commerce, annually thereafter, and if the basic model is
redesigned in such a manner to increase the consumption or decrease the
efficiency of the basic model such that the certified rating is no
longer supported by the test data. Additionally, manufacturers must
report when production of a basic model has ceased and is no longer
offered for sale as part of the next annual certification report
following such cessation. DOE requires the manufacturer of any covered
product or covered equipment to establish, maintain, and retain the
records of certification reports, of the underlying test data for all
certification testing, and of any other testing conducted to satisfy
the requirements of part 429, part 430, and/or part 431. Certification
reports provide DOE and consumers with comprehensive, up-to date
efficiency information and support effective enforcement.
Revised certification data would be required for gas cooking tops
and conventional gas ovens were this SNOPR to be finalized as proposed.
New certification data would be required for electric cooking tops and
conventional electric ovens were this SNOPR to be finalized as
proposed. However, DOE is not proposing new or amended certification or
reporting requirements for consumer conventional cooking products in
this SNOPR. Instead, DOE may consider proposals to establish
certification requirements and reporting for consumer conventional
cooking products under a separate rulemaking regarding appliance and
equipment certification. DOE will address changes to OMB Control Number
1910-1400 at that time, as necessary.
Notwithstanding any other provision of the law, no person is
required to respond to, nor shall any person be subject to a penalty
for failure to comply with, a collection of information subject to the
requirements of the PRA, unless that collection of information displays
a currently valid OMB Control Number.
D. Review Under the National Environmental Policy Act of 1969
DOE is analyzing this proposed regulation in accordance with the
National Environmental Policy Act of 1969 (``NEPA'') and DOE's NEPA
implementing regulations (10 CFR part 1021). DOE's regulations include
a categorical exclusion for rulemakings that establish energy
conservation standards for consumer products or industrial equipment.
10 CFR part 1021, subpart D, appendix B5.1. DOE anticipates that this
rulemaking qualifies for categorical exclusion B5.1 because it is a
rulemaking that establishes energy conservation standards for consumer
products or industrial equipment, none of the exceptions identified in
categorical exclusion B5.1(b) apply, no extraordinary circumstances
exist that require further environmental analysis, and it otherwise
meets the requirements for application of a categorical exclusion. See
10 CFR 1021.410. DOE will complete its NEPA review before issuing the
final rule.
E. Review Under Executive Order 13132
E.O. 13132, ``Federalism,'' 64 FR 43255 (Aug. 10, 1999), imposes
certain requirements on Federal agencies formulating and implementing
policies or regulations that preempt State law or that have federalism
implications. The Executive order requires agencies to examine the
constitutional and statutory authority supporting any action that would
limit the policymaking discretion of the States and to carefully assess
the necessity for such actions. The Executive order also requires
agencies to have an accountable process to ensure meaningful and timely
input by State and local officials in the development of regulatory
policies that have federalism implications. On March 14, 2000, DOE
published a statement of policy describing the intergovernmental
consultation process it will follow in the development of such
regulations. 65 FR 13735. DOE has examined this proposed rule and has
tentatively determined that it would not have a substantial direct
effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government. EPCA governs
and prescribes Federal preemption of State regulations as to energy
conservation for the products that are the subject of this proposed
rule. States can petition DOE for exemption from such preemption to the
extent, and based on criteria, set forth in EPCA. (42 U.S.C. 6297)
Therefore, no further action is required by Executive Order 13132.
F. Review Under Executive Order 12988
With respect to the review of existing regulations and the
promulgation of new regulations, section 3(a) of E.O. 12988, ``Civil
Justice Reform,'' imposes on Federal agencies the general duty to
adhere to the following requirements: (1) eliminate drafting errors and
ambiguity, (2) write regulations to minimize litigation, (3) provide a
clear legal standard for affected conduct rather than a general
standard, and (4) promote simplification and burden reduction. 61 FR
4729 (Feb. 7, 1996). Regarding the review required by section 3(a),
section 3(b) of E.O. 12988 specifically requires that Executive
agencies make every reasonable effort to ensure that the regulation:
(1) clearly specifies the preemptive effect, if any, (2) clearly
specifies any effect on existing Federal law or regulation, (3)
provides a clear legal standard for affected conduct while promoting
simplification and burden reduction, (4) specifies the retroactive
effect, if any, (5) adequately defines key terms, and (6) addresses
other important issues affecting clarity and general draftsmanship
under any guidelines issued by the Attorney General. Section 3(c) of
Executive Order 12988 requires Executive agencies to review regulations
in light of applicable standards in section 3(a) and section 3(b) to
determine whether they are met or it is unreasonable to meet one or
more of them. DOE has completed the required review and determined
that, to the extent permitted by law, this proposed rule meets the
relevant standards of E.O. 12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (``UMRA'')
requires each Federal agency to assess the effects of Federal
regulatory actions on State, local, and Tribal governments and the
private sector. Pub. L. 104-4, section 201 (codified at 2 U.S.C. 1531).
For a proposed regulatory action likely to result in a rule that may
cause the expenditure by State, local, and Tribal governments, in the
aggregate, or by the private sector of $100 million or more in any one
year (adjusted annually for inflation), section 202 of UMRA requires a
Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy.
(2 U.S.C. 1532(a), (b))
[[Page 6900]]
The UMRA also requires a Federal agency to develop an effective process
to permit timely input by elected officers of State, local, and Tribal
governments on a proposed ``significant intergovernmental mandate,''
and requires an agency plan for giving notice and opportunity for
timely input to potentially affected small governments before
establishing any requirements that might significantly or uniquely
affect them. On March 18, 1997, DOE published a statement of policy on
its process for intergovernmental consultation under UMRA. 62 FR 12820.
DOE's policy statement is also available at www.energy.gov/sites/prod/files/gcprod/documents/umra_97.pdf.
Although this proposed rule does not contain a Federal
intergovernmental mandate, it may require expenditures of $100 million
or more in any one year by the private sector. Such expenditures may
include: (1) investment in research and development and in capital
expenditures by consumer conventional cooking products manufacturers in
the years between the final rule and the compliance date for the new
standards and (2) incremental additional expenditures by consumers to
purchase higher-efficiency consumer conventional cooking products,
starting at the compliance date for the applicable standard.
Section 202 of UMRA authorizes a Federal agency to respond to the
content requirements of UMRA in any other statement or analysis that
accompanies the proposed rule. (2 U.S.C. 1532(c)) The content
requirements of section 202(b) of UMRA relevant to a private sector
mandate substantially overlap the economic analysis requirements that
apply under section 325(o) of EPCA and Executive Order 12866. The
SUPPLEMENTARY INFORMATION section of this SNOPR and the TSD for this
proposed rule respond to those requirements.
Under section 205 of UMRA, the Department is obligated to identify
and consider a reasonable number of regulatory alternatives before
promulgating a rule for which a written statement under section 202 is
required. (2 U.S.C. 1535(a)) DOE is required to select from those
alternatives the most cost-effective and least burdensome alternative
that achieves the objectives of the proposed rule unless DOE publishes
an explanation for doing otherwise, or the selection of such an
alternative is inconsistent with law. As required by 42 U.S.C. 6295(m),
this proposed rule would establish new and amended energy conservation
standards for consumer conventional cooking products that are designed
to achieve the maximum improvement in energy efficiency that DOE has
determined to be both technologically feasible and economically
justified, as required by 42 U.S.C. 6295(o)(2)(A) and 42 U.S.C.
6295(o)(3)(B). A full discussion of the alternatives considered by DOE
is presented in chapter 17 of the TSD for this proposed rule.
H. Review Under the Treasury and General Government Appropriations Act,
1999
Section 654 of the Treasury and General Government Appropriations
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family
Policymaking Assessment for any rule that may affect family well-being.
This rule would not have any impact on the autonomy or integrity of the
family as an institution. Accordingly, DOE has concluded that it is not
necessary to prepare a Family Policymaking Assessment.
I. Review Under Executive Order 12630
Pursuant to E.O. 12630, ``Governmental Actions and Interference
with Constitutionally Protected Property Rights,'' 53 FR 8859 (Mar. 15,
1988), DOE has determined that this proposed rule would not result in
any takings that might require compensation under the Fifth Amendment
to the U.S. Constitution.
J. Review Under the Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for Federal agencies to review
most disseminations of information to the public under information
quality guidelines established by each agency pursuant to general
guidelines issued by OMB. OMB's guidelines were published at 67 FR 8452
(Feb. 22, 2002), and DOE's guidelines were published at 67 FR 62446
(Oct. 7, 2002). Pursuant to OMB Memorandum M-19-15, Improving
Implementation of the Information Quality Act (April 24, 2019), DOE
published updated guidelines which are available at www.energy.gov/sites/prod/files/2019/12/f70/DOE%20Final%20Updated%20IQA%20Guidelines%20Dec%202019.pdf. DOE has
reviewed this SNOPR under the OMB and DOE guidelines and has concluded
that it is consistent with applicable policies in those guidelines.
K. Review Under Executive Order 13211
E.O. 13211, ``Actions Concerning Regulations That Significantly
Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 (May 22,
2001), requires Federal agencies to prepare and submit to OIRA at OMB,
a Statement of Energy Effects for any proposed significant energy
action. A ``significant energy action'' is defined as any action by an
agency that promulgates or is expected to lead to promulgation of a
final rule, and that (1) is a significant regulatory action under
Executive Order 12866, or any successor order; and (2) is likely to
have a significant adverse effect on the supply, distribution, or use
of energy, or (3) is designated by the Administrator of OIRA as a
significant energy action. For any proposed significant energy action,
the agency must give a detailed statement of any adverse effects on
energy supply, distribution, or use should the proposal be implemented,
and of reasonable alternatives to the action and their expected
benefits on energy supply, distribution, and use.
DOE has tentatively concluded that this regulatory action, which
proposes new and amended energy conservation standards for consumer
conventional cooking products, is not a significant energy action
because the proposed standards are not likely to have a significant
adverse effect on the supply, distribution, or use of energy, nor has
it been designated as such by the Administrator at OIRA. Accordingly,
DOE has not prepared a Statement of Energy Effects on this proposed
rule.
L. Information Quality
On December 16, 2004, OMB, in consultation with the Office of
Science and Technology Policy (``OSTP''), issued its Final Information
Quality Bulletin for Peer Review (``the Bulletin''). 70 FR 2664 (Jan.
14, 2005). The Bulletin establishes that certain scientific information
shall be peer reviewed by qualified specialists before it is
disseminated by the Federal Government, including influential
scientific information related to agency regulatory actions. The
purpose of the bulletin is to enhance the quality and credibility of
the Government's scientific information. Under the Bulletin, the energy
conservation standards rulemaking analyses are ``influential scientific
information,'' which the Bulletin defines as ``scientific information
the agency reasonably can determine will have, or does have, a clear
and substantial impact on important public policies or private sector
decisions.'' 70 FR 2664, 2667.
In response to OMB's Bulletin, DOE conducted formal peer reviews of
the energy conservation standards development process and the analyses
that are typically used and has prepared
[[Page 6901]]
a report describing that peer review.\123\ Generation of this report
involved a rigorous, formal, and documented evaluation using objective
criteria and qualified and independent reviewers to make a judgment as
to the technical/scientific/business merit, the actual or anticipated
results, and the productivity and management effectiveness of programs
and/or projects. Because available data, models, and technological
understanding have changed since 2007, DOE has engaged with the
National Academy of Sciences to review DOE's analytical methodologies
to ascertain whether modifications are needed to improve the
Department's analyses. DOE is in the process of evaluating the
resulting report.\124\

section at the beginning of this document. Webinar registration
information, participant instructions, and information about the
capabilities available to webinar participants will be published on
DOE's website at www1.eere.energy.gov/buildings/appliance_standards/standards.aspx?productid=34. Participants are responsible for ensuring
their systems are compatible with the webinar software.
B. Procedure for Submitting Prepared General Statements for
Distribution
Any person who has an interest in the topics addressed in this
document, or who is representative of a group or class of persons that
has an interest in these issues, may request an opportunity to make an
oral presentation at the webinar. Such persons may submit to
[email protected]. Persons who wish to speak
should include with their request a computer file in WordPerfect,
Microsoft Word, PDF, or text (ASCII) file format that briefly describes
the nature of their interest in this rulemaking and the topics they
wish to discuss. Such persons should also provide a daytime telephone
number where they can be reached.
DOE requests persons selected to make an oral presentation to
submit an advance copy of their statements at least two weeks before
the webinar. At its discretion, DOE may permit persons who cannot
supply an advance copy of their statement to participate, if those
persons have made advance alternative arrangements with the Building
Technologies Office. As necessary, requests to give an oral
presentation should ask for such alternative arrangements.
C. Conduct of the Webinar
DOE will designate a DOE official to preside at the webinar/public
meeting and may also use a professional facilitator to aid discussion.
The meeting will not be a judicial or evidentiary-type public hearing,
but DOE will conduct it in accordance with section 336 of EPCA. (42
U.S.C. 6306) A court reporter will be present to record the proceedings
and prepare a transcript. DOE reserves the right to schedule the order
of presentations and to establish the procedures governing the conduct
of the webinar. There shall not be discussion of proprietary
information, costs or prices, market share, or other commercial matters
regulated by U.S. anti-trust laws. After the webinar and until the end
of the comment period, interested parties may submit further comments
on the proceedings, as well as on any aspect of the rulemaking.
The webinar will be conducted in an informal, conference style. DOE
will present a general overview of the topics addressed in this
rulemaking, allow time for prepared general statements by participants,
and encourage all interested parties to share their views on issues
affecting this rulemaking. Each participant will be allowed to make a
general statement (within time limits determined by DOE), before the
discussion of specific topics. DOE will allow, as time permits, other
participants to comment briefly on any general statements.
At the end of all prepared statements on a topic, DOE will permit
participants to clarify their statements briefly. Participants should
be prepared to answer questions by DOE and by other participants
concerning these issues. DOE representatives may also ask questions of
participants concerning other matters relevant to this rulemaking. The
official conducting the webinar/public meeting will accept additional
comments or questions from those attending, as time permits. The
presiding official will announce any further procedural rules or
modification of the previous procedures that may be needed for the
proper conduct of the webinar.
A transcript of the webinar will be included in the docket, which
can be viewed as described in the Docket section at the beginning of
this document and will be accessible on the DOE website. In addition,
any person may buy a copy of the transcript from the transcribing
reporter.

E. Issues on Which DOE Seeks Comment
Although DOE welcomes comments on any aspect of this proposal, DOE
is particularly interested in receiving comments and views of
interested parties concerning the following issues:
(1) DOE requests comment on its proposed definition for portable
conventional cooking top and DOE's proposal to include portable
conventional cooking tops in the existing product classes. DOE also
seeks data and information on its initial determination not to
differentiate conventional cooking tops on the basis of portability
when considering product classes for this SNOPR analysis.

on energy consumption and associated data about such impacts. DOE
further requests comment on its proposal to not include the energy
consumption of any downdraft venting system in the energy conservation
standards for conventional cooking tops.
(3) DOE requests comment on its proposed tested configuration and
determination of representative IAEC for single-zone non-portable
cooking tops.
(4) DOE requests comment on its proposal to not define ``basic
model'' with respect to cooking products or cooking tops, and on
possible definitions for ``basic model'' with respect to cooking
products or cooking tops that could be used if DOE were to determine
such a definition is necessary.
(5) DOE welcomes data on the consumer usage patterns of pyrolytic
versus non-pyrolytic self-cleaning functions in conventional ovens, and
requests comment on its preliminary determination that self-cleaning
technologies do not warrant separate product class considerations.

types between electric and gas cooking products.
(26) DOE requests data on the market size and typical selling price
of units sold through the second-hand market for cooking products.
(27) DOE welcomes input on the effect of new and amended standards
on impacts across products within the same fuel class and equipment
type.
(28) DOE seeks comment on the general approach to its shipments
methodology.
(29) DOE seeks feedback on its assumption of no rebound effect
associated with the use of more efficient conventional cooking products
as a result of a standard.
(30) DOE requests comment on whether additional consumer subgroups,
including any disaggregation of the subgroups analyzed in this SNOPR,
may be disproportionately affected by a new or amended national
standard and warrant additional analysis in the final rule.
(31) DOE requests comment on the use of 9.1 percent as an
appropriate real discount rate for consumer conventional cooking
product manufacturers.
(32) DOE seeks comment on any health impacts to consumers,
environmental impacts, or general public health and welfare impacts
(including the distribution of such impacts across sensitive
populations) of its proposals in this SNOPR on on-site emissions from
gas cooking products of methane, carbon dioxide, particulate matter,
nitrogen dioxide, or other hazardous air emissions. DOE also seeks
comment on whether manufacturers are instituting design approaches,

stakeholders may also provide comments separately to DOJ regarding
these potential impacts. See the ADDRESSES section for information to
send comments to DOJ.
(38) DOE seeks comment on any impacts of its proposals in this
SNOPR on indoor air pollutants released by gas cooking products, as
well as any other design approaches, control strategies, or other
measures to mitigate these emissions.
(39) DOE welcomes data submissions and comments that will provide
for a fuller assessment of the potential impact of energy conservation
standards on consumer choice and how to quantify this impact in its
regulatory analysis in future rulemakings.
(40) DOE seeks comment and data to potentially re-evaluate the
sampling plan for cooking tops in the context of any potential
performance standards for these products.
(41) DOE requests comment on its findings that there are 15
domestic small businesses that manufacture conventional cooking
products and its estimate of the potential impacts on these small
businesses. Additionally, DOE requests comment on the potential for any
small businesses to exit the consumer conventional cooking products
market in response to the proposed energy conservation standards.
(42) DOE seeks comment on the policy alternatives presented in the
regulatory impact analysis and data that can be used to estimate the
manufacturer response to Federal credits.
Additionally, DOE welcomes comments on other issues relevant to the
conduct of this rulemaking that may not specifically be identified in
this document.
VIII. Approval of the Office of the Secretary
The Secretary of Energy has approved publication of this
supplemental notice of proposed rulemaking and announcement of public
meeting.

Signed in Washington, DC, on January 10, 2023.
Treena V. Garrett,
Federal Register Liaison Officer, U.S. Department of Energy.
For the reasons set forth in the preamble, DOE proposes to amend
parts 429 and 430 of chapter II, subchapter D, of title 10 of the Code
of Federal Regulations, as set forth below:
PART 429--CERTIFICATION, COMPLIANCE, AND ENFORCEMENT FOR CONSUMER
PRODUCTS AND COMMERCIAL AND INDUSTRIAL EQUIPMENT
0
1. The authority citation for part 429 continues to read as follows:
Authority: 42 U.S.C. 6291-6317; 28 U.S.C. 2461 note.
0
2. Amend Sec. 429.23 by revising paragraph (a) to read as follows:
Sec. 429.23 Cooking products.
(a) Determination of represented values. Manufacturers must
determine the represented values, which include the certified ratings,
for each basic model of cooking product by testing, in conjunction with
the applicable sampling provisions.
(1) Sampling plan for selection of units for testing. (i) The
requirements of
[[Page 6904]]
Sec. 429.11 are applicable to cooking products; and
(ii) For each basic model of cooking product, a sample of
sufficient size shall be randomly selected and tested to ensure that
any represented value of estimated annual operating cost, standby mode
power consumption, off mode power consumption, annual energy
consumption, integrated annual energy consumption, or other measure of
energy consumption of a basic model for which consumers would favor
lower values shall be greater than or equal to the higher of:
(A) The mean of the sample, where:
[GRAPHIC] [TIFF OMITTED] TP01FE23.000
and x is the sample mean; n is the number of samples; and
xi is the ith sample; Or,
(B) The upper 97\1/2\ percent confidence limit (UCL) of the true
mean divided by 1.05, where:
[GRAPHIC] [TIFF OMITTED] TP01FE23.001
And x is the sample mean; s is the sample standard deviation; n is
the number of samples; and t0.975 is the t statistic for a
97.5% one-tailed confidence interval with n-1 degrees of freedom (from
appendix A).
(2) Product-specific provisions for determination of represented
values. (i) Non-portable conventional cooking tops with a single
cooking zone.
(A) Representations for a basic model must be based on the tested
configuration. For the purpose of this paragraph (a)(2)(i), the
``tested configuration'' means:
(1) The non-portable conventional cooking top unit containing the
single cooking zone, and
(2) If commercially available from the same manufacturer, the non-
portable conventional cooking top unit that has similar design
characteristics (e.g., construction materials, user interface) as the
non-portable conventional cooking top containing the single cooking
zone, but that contains two cooking zones that are within the same
product class and use the same heating technology (i.e., gas flame,
electric resistive heating, or electric inductive heating) and energy
source (e.g., voltage, gas type) as the non-portable conventional
cooking top containing the single cooking zone. If more than one such
comparable unit with two cooking zones is commercially available from
the same manufacturer, the least energy consumptive of those units with
two cooking zones shall be included in the tested configuration. If no
such comparable unit with two cooking zones is commercially available
from the same manufacturer, the tested configuration shall be only the
non-portable conventional cooking top unit containing the single
cooking zone.
(B) Determination of the represented value of integrated annual
energy consumption (IAEC) of the tested configuration of a non-portable
conventional cooking top with a single cooking zone.
(1) If the tested configuration includes a comparable non-portable
conventional cooking top unit containing two cooking zones, the
represented value of IAEC is calculated as follows:
IAEC = \1/3\ x IAECsingle x \2/3\ x IAECdouble
Where:
IAECsingle is the IAEC for the non-portable conventional
cooking top unit containing the single cooking zone included in the
tested configuration as determined in Sec. 430.23(i)(2) of this
chapter; and
IAECdouble is the IAEC for the comparable non-portable
conventional cooking top unit containing two cooking zones included
in the tested configuration as determined in Sec. 430.23(i)(2) of
this chapter.
(2) If the tested configuration includes only the non-portable
conventional cooking top unit containing the single cooking zone, the
represented value of IAEC is equal to that cooking top's IAEC as
determined in Sec. 430.23(i)(2) of this chapter.
