Integrated System Rate Schedules

AGENCY: Southwestern Power Administration, DOE.

ACTION: Notice of extension of integrated system rate schedules.

-----------------------------------------------------------------------

SUMMARY: The Administrator, Southwestern Power Administration 
(Southwestern) has approved and placed into effect on an interim basis 
Rate Order No. SWPA-77, which extends the following existing 
Southwestern Integrated System rate schedules: Rate Schedule P-13A, 
Wholesale Rates for Hydro Peaking Power; Rate Schedule NFTS-13A, 
Wholesale Rates for Non-Federal Transmission/Interconnection Facilities 
Service; and Rate Schedule EE-13, Wholesale Rates for Excess Energy. 
This is an interim rate action effective October 1, 2021, extending for 
a period of two years through September 30, 2023.

DATES: The effective period for the rate schedules specified in Rate 
Order No. SWPA-77 is October 1, 2021, through September 30, 2023.

FOR FURTHER INFORMATION CONTACT: Ms. Fritha Ohlson, Senior Vice 
President and Chief Operating Officer, Office of Corporate Operations, 
Southwestern Power Administration, U.S. Department of Energy, One West 
Third Street, Tulsa, Oklahoma 74103, (918) 595-6684 or email: 
[email protected].

SUPPLEMENTARY INFORMATION: Rate Order No. SWPA-77 is approved and 
placed into effect on an interim basis for the period October 1, 2021, 
through September 30, 2023, for the following Southwestern Integrated 
System rate schedules:

Rate Schedule P-13A, Wholesale Rates for Hydro Peaking Power
Rate Schedule NFTS-13A, Wholesale Rates for Non-Federal Transmission/
Interconnection Facilities Service
Rate Schedule EE-13, Wholesale Rates for Excess Energy

Decision Rationale

    The Southwestern Administrator completed an annual review of the 
continuing adequacy of the existing rate schedules for the Integrated 
System. This review, as presented in the 2021 Integrated System Power 
Repayment Studies (PRSs), indicated the need for a 1.3 percent revenue 
increase to continue to satisfy cost recovery criteria. It is 
Southwestern practice for the Administrator to defer, on a case-by-case 
basis, revenue adjustments for the Integrated System if such 
adjustments are within plus or minus two percent of the revenue 
estimate based on the current Integrated System rate schedules. The 
deferral of a revenue adjustment (rate change) provides for rate 
stability and savings on the administrative costs of implementation. 
The Administrator determined it to be prudent to defer the increase and 
allow the current Integrated System rate schedules, which are set to 
expire September 30, 2021, to remain in effect.
    To ensure that Southwestern has rate schedules in effect for 
collection of revenue in order to meet its repayment obligations, the 
Administrator has approved and placed into effect a two-year extension 
of the Integrated System rate schedules for the period October 1, 2021, 
through September 30, 2023.
    The Administrator followed part 903, subpart A of title 10 of the 
Code of Federal Regulations (CFR), ``Procedures for Public 
Participation in Power and Transmission Rate Adjustments and 
Extensions'' for the extension of the rate schedules. The public was 
informed by notice, published in the Federal Register (86 FR 31500 
(June 14, 2021)) of the proposed extension of the rate schedules and of 
the opportunity to provide written comments for a period of 30 days 
ending July 14, 2021. No comments were received.

Legal Authority

    By Delegation Order No. 00-037.00B, effective November 19, 2016, 
the Secretary of Energy delegated: (1) The authority to develop power 
and transmission rates to the Southwestern Administrator; (2) the 
authority to confirm, approve, and place such rates into effect on an 
interim basis to the Deputy Secretary of Energy; and (3) the authority 
to confirm, approve, and place into effect on a final basis, or to 
remand or disapprove such rates, to the Federal Energy Regulatory 
Commission (FERC). By Delegation Order No. S1-DEL-S4-2021, effective 
February 25, 2021, the Acting Secretary of Energy also delegated the 
authority to confirm, approve, and place such rates into effect on an 
interim basis to the Under Secretary for Science (and Energy). By 
Redelegation Order No. S4-DEL-OE1-2021, effective March 25, 2021, the 
Acting Under Secretary for Science (and Energy) redelegated the 
authority to confirm, approve, and place such rates into effect on an 
interim basis to the Assistant Secretary for Electricity. And by 
Redelegation Order No. 00-002.10-04, effective July 8, 2020, the 
Assistant Secretary for Electricity further redelegated the authority 
to confirm, approve, and place such rates into effect on an interim 
basis to the Southwestern Administrator. This redelegation order, 
despite predating the February 2021 delegation and March 2021 
redelegation, remains valid. By these delegations, and in accordance 
with 10 CFR 903.22(h) and 10 CFR 903.23(a), as amended, (84 FR 5347, 
5350 (Feb. 21, 2019)), the Administrator may approve and extend, on an 
interim basis, rates previously confirmed and approved by FERC beyond 
the period specified by FERC.

Environmental Impact

    Southwestern previously determined that the rate change actions, 
placed into effect on October 1, 2013 for the Integrated System fit 
within the class of categorically excluded actions as listed in 
appendix B to subpart D of 10 CFR part 1021, the Implementing 
Procedures and Guidelines of the National Environmental Policy Act of 
1969, as amended (42 U.S.C. 4321-4347), categorical exclusions 
applicable to B4.3: Electric power marketing rate changes, which does 
not require preparation of either an environmental impact statement 
(EIS) or an environmental assessment (EA). On May 27, 2021, 
Southwestern determined that categorical exclusion B4.3 applies to the 
current action.

Determination Under Executive Order 12866

    Southwestern has an exemption from centralized regulatory review 
under Executive Order 12866; accordingly, no clearance of this notice 
by the Office of Management and Budget is required.

Rate Schedules
Rate Order No. SWPA-77

ORDER APPROVING EXTENSION OF RATE SCHEDULES ON AN INTERIM BASIS

(August 30, 2021)
    Pursuant to Sections 301(b) and 302(a) and of the Department of 
Energy Organization Act, Public Law 42 U.S.C. 7151(b) and 7152(a), the 
functions of the Secretary of the Interior and the Federal Power 
Commission under Section 5 of the Flood Control Act of 1944, 16 U.S.C. 
825s, relating to the Southwestern Power Administration (Southwestern), 
were transferred to, and vested in the Secretary of Energy. By 
Delegation Order No. 00-037.00B, effective November 19, 2016, the 
Secretary of Energy delegated: (1) The authority to develop power and 
transmission rates to the Southwestern Administrator; (2) the authority 
to confirm, approve, and place such rates into effect on an interim 
basis to the Deputy Secretary of Energy; and (3) the authority to 
confirm, approve, and place into effect on a final basis, or to remand 
or disapprove such rates, to the Federal Energy Regulatory Commission 
(FERC). By Delegation Order No. S1-DEL-S4-2021, effective February 25, 
2021, the Acting Secretary of Energy also delegated the authority to 
confirm, approve, and place such rates into effect on an interim basis 
to the Under Secretary for Science (and Energy). By Redelegation Order 
No. S4-DEL-OE1-2021, effective March 25, 2021, the Acting Under 
Secretary for Science (and Energy) redelegated the authority to 
confirm, approve, and place such rates into effect on an interim basis 
to the Assistant Secretary for Electricity. And by Redelegation Order 
No. 00-002.10-04, effective July 8, 2020, the Assistant Secretary for 
Electricity further redelegated the authority to confirm, approve, and 
place such rates into effect on an interim basis to the Southwestern 
Administrator. This redelegation order, despite predating the February 
2021 delegation and March 2021 redelegation, remains valid. By these 
delegations, and in accordance with 10 CFR 903.22(h) and 10 CFR 
903.23(a), as amended, (84 FR 5347, 5350 (Feb. 21, 2019)), the 
Southwestern Administrator may approve and extend, on an interim basis, 
rates previously confirmed and approved by FERC beyond the period 
specified by FERC. Pursuant to that delegated authority, the 
Southwestern Administrator has issued this interim rate order.

BACKGROUND

    The following rate schedules for the Integrated System were 
confirmed and approved on a final basis by FERC on January 9, 2014, in 
Docket No. EF14-1-000 (146 FERC ] 62,016) for the period October 1, 
2013, through September 30, 2017:

Rate Schedule P-13, Wholesale Rates for Hydro Peaking Power
Rate Schedule NFTS-13, Wholesale Rates for Non-Federal Transmission/
Interconnection Facilities Service
Rate Schedule EE-13, Wholesale Rates for Excess Energy

    Since initial FERC approval, Southwestern added a new section 
within rate schedule NFTS-13 with no revenue adjustment and the revised 
rate schedule was designated NFTS-13A to reflect the change. The 
following rate schedule was placed into effect on an interim basis by 
the Deputy Secretary for Energy, effective January 1, 2017, and was 
confirmed and approved on a final basis by FERC on March 9, 2017, in 
Docket No. EF14-1-001 (158 FERC ] 62,182):

Rate Schedule NFTS-13A, Wholesale Rates for Non-Federal Transmission/
Interconnection Facilities Service

A two-year extension of all Integrated System rate schedules was 
approved on an interim basis by the Deputy Secretary in Docket No. 
EF14-1-002 for the period October 1, 2017, through September 30, 2019. 
Subsequently, Southwestern added a new section within rate schedule P-
13 with no revenue adjustment and the revised rate schedule was 
designated P-13A to reflect the change. The following rate schedule was 
placed into effect on an interim basis by the Assistant Secretary for 
Electricity, effective July 1, 2019, and was confirmed and approved on 
a final basis by FERC on August 29, 2019, in Docket No. EF14-1-003 (168 
FERC ] 62,125):

Rate Schedule P-13A, Wholesale Rates for Hydro Peaking Power

A two-year extension of all Integrated System rate schedules was 
approved on an interim basis by the Assistant Secretary for Electricity 
for the period of

[[Page 51143]]

October 1, 2019, through September 30, 2021.

DISCUSSION

    The existing Integrated System rate schedules are based on the 
Southwestern 2013 Power Repayment Studies (PRSs). PRSs have been 
completed for the Integrated System each year since approval of the 
existing rate schedules. Since 2013, subsequent PRSs have indicated the 
need for a minimal rate increase, all within the plus or minus two 
percent rate adjustment threshold practice established by the 
Administrator on June 23, 1987. Therefore, the Administrator deferred 
these rate adjustments in the best interest of the government.
    However, the existing rate schedules are set to expire on September 
30, 2021. Consequently, Southwestern proposed to extend the existing 
rate schedules for a two-year period ending September 30, 2023, on an 
interim basis under the implementation authorities noted in 10 CFR 
903.22(h) and 10 CFR 903.23(a).
    Southwestern followed 10 CFR part 903, ``Procedures for Public 
Participation in Power and Transmission Rate Adjustments and 
Extensions,'' for the proposed extension of the rate schedules. An 
opportunity for customers and other interested members of the public to 
review and comment on the proposed extension of the rate schedules was 
announced by notice, published in the Federal Register on June 14, 2021 
(86 FR 31500), with written comments due by July 14, 2021.

COMMENTS AND RESPONSES

    Southwestern received no comments regarding the extension of the 
rate schedules.

AVAILABILITY OF INFORMATION

    Information regarding the extension of the rate schedules is 
available for public review in the offices of Southwestern Power 
Administration, Williams Tower I, One West Third Street, Tulsa, 
Oklahoma 74103. The rate schedules are available on the Southwestern 
website at www.swpa.gov.

ADMINISTRATION'S CERTIFICATION

    The 2013 Integrated System PRSs indicated that the current rate 
schedules will repay all costs of the Integrated System, including 
amortization of the power investment consistent with the provisions of 
Department of Energy Order No. RA 6120.2. The 2021 Integrated System 
PRSs indicated the need for an annual revenue increase of 1.3 percent. 
However, the 2021 rate adjustment falls within the Southwestern 
established plus or minus two percent Integrated System rate adjustment 
threshold practice and was deferred.
    The Southwestern 2022 PRSs will determine the appropriate level of 
revenues needed for the next rate period. In accordance with Delegation 
Order No. 00-037.00B, effective November 19, 2016, and Section 5 of the 
Flood Control Act of 1944, the Administrator has determined that the 
existing rate schedules are the lowest possible rates consistent with 
sound business principles, and their extension is consistent with 
applicable law.

ENVIRONMENT

    Southwestern previously determined that the rate change actions, 
placed into effect on October 1, 2013 for the Integrated System, fit 
within the class of categorically excluded actions as listed in 
appendix B to subpart D of 10 CFR part 1021, the Implementing 
Procedures and Guidelines of the National Environmental Policy Act of 
1969, as amended (42 U.S.C. 4321-4347), categorical exclusions 
applicable to B4.3: Electric power marketing rate changes, which does 
not require preparation of either an environmental impact statement 
(EIS) or an environmental assessment (EA). On May 27, 2021, 
Southwestern determined that categorical exclusion B4.3 applies to the 
current action.

ADMINISTRATIVE PROCEDURES

    Under the Administrative Procedure Act (5 U.S.C. 553(d)), 
publication or service of a substantive rule must be made not less than 
30 days before its effective date, except (1) a substantive rule that 
grants or recognizes an exemption or relieves a restriction; (2) 
interpretative rules and statements of policy; or (3) as otherwise 
provided by the agency for good cause found and published with the 
rule. The Administrator finds good cause to waive the 30-day delay in 
the effective date of this action as unnecessary for the following 
reasons: (1) This is an extension of rates previously approved by FERC, 
pursuant to 10 CFR 903.23(a); (2) there are no substantive changes, as 
the existing rate schedules and anticipated revenues remain the same; 
and (3) the Administrator provided notice and opportunity for public 
comment more than 30 days prior to the effective date of the rate 
extension and received no comments.

ORDER

    In view of the foregoing, and pursuant to delegated authority from 
the Secretary of Energy, I hereby extend on an interim basis, for the 
period of two years, effective October 1, 2021, through September 30, 
2023, the current Integrated System rate schedules:

Rate Schedule P-13A, Wholesale Rates for Hydro Peaking Power
Rate Schedule NFTS-13A, Wholesale Rates for Non-Federal Transmission/
Interconnection Facilities Service
Rate Schedule EE-13, Wholesale Rates for Excess Energy

includes the associated Regulation Purchased Adder, the Customer must 
pursue these services from a different host Balancing Authority; 
thereby moving all metered loads and resources from Southwestern's 
Balancing Authority Area to the Balancing Authority Area of the new 
host Balancing Authority. Until such time as that meter reconfiguration 
is accomplished, the Customer will be charged for the Regulation and 
Frequency Response Service and applicable Adder then in effect. The 
Customer must notify Southwestern by July 1 of this choice, to be 
effective the subsequent calendar year.
2.4.5. Regulation Purchased Adder
    Southwestern has determined the amount of energy used from storage 
to provide Regulation and Frequency Response Service in order to meet 
Southwestern's Balancing Authority Area requirements. The replacement 
value of such energy used shall be recovered through the Regulation 
Purchased Adder. The Regulation Purchased Adder during the time period 
of January 1 through December 31 of the current calendar year is based 
on the average annual use of energy from storage \1\ for Regulation and 
Frequency Response Service and Southwestern's estimated purchased power 
price for the corresponding year from the most currently approved Power 
Repayment Studies.
---------------------------------------------------------------------------

    \1\ The average annual use of energy from storage for Regulation 
and Frequency Response Service is based on Southwestern studies.
---------------------------------------------------------------------------

    The Regulation Purchased Adder will be phased in over a period of 
four (4) years as follows:

------------------------------------------------------------------------
                                          Regulation purchased adder for
                                            the incremental replacement
                  Year                       value of energy used from
                                                      storage
------------------------------------------------------------------------
2014....................................  \1/4\ of the average annual
                                           use of energy from storage x
                                           2014 Purchased Power price.
2015....................................  \1/2\ of the average annual
                                           use of energy from storage x

2016....................................  \3/4\ of the average annual
                                           use of energy from storage x
                                           2016 Purchased Power price.
2017 and thereafter.....................  The total average annual use
                                           of energy from storage x the
                                           applicable Purchased Power
                                           price.
------------------------------------------------------------------------

2.4.5.1. Applicability of Regulation Purchased Adder
    The replacement value of the estimated annual use of energy from 
storage for Regulation and Frequency Response Service shall be 
recovered by Customers located within Southwestern's Balancing 
Authority Area on a non-coincident peak ratio share basis, divided into 
twelve equal monthly payments, in accordance with the formula in 
Section 2.4.5.2.
    If the Regulation Purchased Adder is determined and applied under 
Southwestern's Rate Schedule NFTS-13A, then it shall not be applied 
here.
2.4.5.2. Procedure for Determining Regulation Purchased Adder
    Unless otherwise specified by contract, the Regulation Purchased 
Adder for an individual Customer shall be based on the following 
formula rate, calculated to include the replacement value of the 
estimated annual use of

[[Page 51147]]

energy from storage by Southwestern for Regulation and Frequency 
Response Service.

RPA = The Regulation Purchased Adder for an individual Customer per 
month, which is as follows:

[(L Customer / L Total) x RP Total 
] / 12

with the factors defined as follows:

L Customer = The sum in MW of the following three 
factors:
    (1) The Customer's highest metered load plus generation used to 
serve the Customer's load that is accounted for through a reduction 
in the Customer's metered load (referred to as `generation behind 
the meter') during the previous calendar year, and
    (2) The Customer's highest rate of Scheduled Exports \2\ during 
the previous calendar year, and
    (3) The Customer's highest rate of Scheduled Imports \2\ during 
the previous calendar year.
---------------------------------------------------------------------------

    \2\ Scheduled Exports and Scheduled Imports are transactions, 
such as sales and purchases respectively, which are in addition to a 
Customer's metered load that contribute to Southwestern's Balancing 
Authority Area need for regulation.
---------------------------------------------------------------------------

L Total = The sum of all L Customer factors for all 
Customers that were inside Southwestern's Balancing Authority Area 
at the beginning of the previous calendar year in MW.
RP Total = The ``net'' cost in dollars and cents based on 
Southwestern's estimated purchased power price for the corresponding 
year from the most currently approved Power Repayment Studies 
multiplied by the average annual use of energy from storage, as 
provided for in the table in Section 2.4.5, to support 
Southwestern's ability to regulate within its Balancing Authority 
Area. The ``net'' cost in dollars and cents shall be adjusted by 
subtracting the product of the quantity of such average annual use 
of energy from storage in MWh and Southwestern's highest rate in 
dollars per MWh for Supplemental Peaking Energy during the previous 
calendar year.

    For Customers that have aggregated their load, resources, and 
scheduling into a single node by contract within Southwestern's 
Balancing Authority Area, the individual Customer's respective 
Regulation Purchased Adder shall be that Customer's ratio share of the 
Regulation Purchased Adder established for the node. Such ratio share 
shall be determined for the Customer on a non-coincident basis and 
shall be calculated for the Customer from their highest metered load 
plus generation behind the meter.
2.4.6. Energy Imbalance Service Limitations
    Energy Imbalance Service primarily applies to deliveries of power 
and energy which are required to satisfy a Customer's load. As Hydro 
Peaking Power and associated energy are limited by contract, the Energy 
Imbalance Service bandwidth specified for Non-Federal Transmission 
Service does not apply to deliveries of Hydro Peaking Power, and 
therefore Energy Imbalance Service is not charged on such deliveries. 
Customers who consume a capacity of Hydro Peaking Power greater than 
their Peaking Contract Demand may be subject to a Capacity Overrun 
Penalty.

3. Hydro Peaking Power Penalties, Terms, and Conditions

3.1. Capacity Overrun Penalty

3.1.1. Penalty Charge for Capacity Overrun
    For each hour during which Hydro Peaking Power was provided at a 
rate greater than that to which the Customer is entitled, the Customer 
will be charged a Capacity Overrun Penalty at the following rates:

------------------------------------------------------------------------
                                                             Rate per
              Months associated with charge                  kilowatt
------------------------------------------------------------------------
March, April, May, October, November, December..........           $0.15
January, February, June, July, August, September........            0.30
------------------------------------------------------------------------

3.1.2. Applicability of Capacity Overrun Penalty
    Customers which have loads within Southwestern's Balancing 
Authority Area are obligated by contract to provide resources, over and 
above the Hydro Peaking Power and associated energy purchased from 
Southwestern, sufficient to meet their loads. A Capacity Overrun 
Penalty shall be applied only when the formulas provided in Customers' 
respective Power Sales Contracts indicate an overrun on Hydro Peaking 
Power, and investigation determines that all resources, both firm and 
non-firm, which were available at the time of the apparent overrun were 
insufficient to meet the Customer's load.

3.2. Energy Overrun Penalty

3.2.1. Penalty Charge for Energy Overrun
    $0.1034 per kilowatthour for each kilowatthour of overrun.
3.2.2. Applicability of Energy Overrun Penalty
    By contract, the Customer is subject to limitations on the maximum 
amounts of Peaking Energy which may be scheduled under the Customer's 
Power Sales Contract. When the Customer schedules an amount in excess 
of such maximum amounts, such Customer is subject to the Energy Overrun 
Penalty.

3.3. Power Factor Penalty

3.3.1. Requirements Related to Power Factor
    Any Customer served from facilities owned by or available by 
contract to Southwestern will be required to maintain a power factor of 
not less than 95 percent and will be subject to the following 
provisions.
3.3.2. Determination of Power Factor
    The power factor will be determined for all Demand Periods and 
shall be calculated under the formula:
[GRAPHIC] [TIFF OMITTED] TN14SE21.000

with the factors defined as follows:

PF = The power factor for any Demand Period of the month.
kWh = The total quantity of energy which is delivered during such 
Demand Period to the point of delivery or interconnection in 
accordance with Section 3.3.4.
rkVAh = The total quantity of reactive kilovolt-ampere-hours (kVARs) 
delivered during such Demand Period to the point of delivery or 
interconnection in accordance with Section 3.3.4.
3.3.3. Penalty Charge for Power Factor
    The Customer shall be assessed a penalty for all Demand Periods of 
a month where the power factor is less than 95 percent lagging. For any 
Demand Period during a particular month such penalty shall be in 
accordance with the following formula:

C = D x (0.95-LPF) x $0.10

with the factors defined as follows:

C = The charge in dollars to be assessed for any particular Demand 
Period of such month that the determination of power

[[Page 51148]]

factor ``PF'' is calculated to be less than 95 percent lagging.
D = The Customer's demand in kilowatts at the point of delivery for 
such Demand Period in which a low power factor was calculated.
LPF = The lagging power factor, if any, determined by the formula 
``PF'' for such Demand Period.

    If C is negative, then C = zero (0).
3.3.4. Applicability of Power Factor Penalty
    The Power Factor Penalty is applicable to radial interconnections 
with the System of Southwestern. The total Power Factor Penalty for any 
month shall be the sum of all charges ``C'' for all Demand Periods of 
such month. No penalty is assessed for leading power factor. 
Southwestern, in its sole judgment and at its sole option, may 
determine whether power factor calculations should be applied to (i) a 
single physical point of delivery, (ii) a combination of physical 
points of delivery where a Customer has a single, electrically 
integrated load, (iii) or interconnections. The general criteria for 
such decision shall be that, given the configuration of the Customer's 
and Southwestern's systems, Southwestern will determine, in its sole 
judgment and at its sole option, whether the power factor calculation 
more accurately assesses the detrimental impact on Southwestern's 
system when the above formula is calculated for a single physical point 
of delivery, a combination of physical points of delivery, or for an 
interconnection as specified by an Interconnection Agreement.
    Southwestern, at its sole option, may reduce or waive Power Factor 
Penalties when, in Southwestern's sole judgment, low power factor 
conditions were not detrimental to the System of Southwestern due to 
particular loading and voltage conditions at the time the power factor 
dropped below 95 percent lagging.

4. Hydro Peaking Power Miscellaneous Rates, Terms, and Conditions

4.1. Real Power Losses

    Customers are required to self-provide all Real Power Losses for 
non-Federal energy transmitted by Southwestern on behalf of such 
Customers under the provisions detailed below.

Customer's monthly Real Power Losses are computed each month on a 
megawatthour basis as follows:

ML = 0.04 x NFE

with the factors defined as follows:

ML = The total monthly loss energy, rounded to the nearest 
megawatthour, to be scheduled by a Customer for receipt by 
Southwestern for Real Power Losses associated with non-Federal 
energy transmitted on behalf of such Customer; and
NFE = The amount of non-Federal energy that was transmitted by 
Southwestern on behalf of a Customer during a particular month.

and energy over the System of Southwestern unless such Customer has 
accounted for Real Power Losses as part of a metering arrangement with 
Southwestern.
    4.1.2. On or before the twentieth day of each month, Southwestern 
shall determine the amount of non-Federal loss energy it provided on 
behalf of the Customer during the previous month and provide a written 
schedule to the Customer setting forth hour-by-hour the quantities of 
non-Federal energy to be delivered to Southwestern as losses during the 
next month.
    4.1.3. Real Power Losses not delivered to Southwestern by the 
Customer, according to the schedule provided, during the month in which 
such losses are due shall be billed by Southwestern to the Customer to 
adjust the end-of-month loss energy balance to zero (0) megawatthours 
and the Customer shall be obliged to purchase such energy at the 
following rates:

------------------------------------------------------------------------
                                                             Rate per

Customer must pursue these services from a different host Balancing 
Authority; thereby moving all metered loads and resources from 
Southwestern's Balancing Authority Area to the Balancing Authority Area 
of the new host Balancing Authority. Until such time as that meter 
reconfiguration is accomplished, the Customer will be charged for the 
Regulation and Frequency Response Service and applicable Adder then in 
effect. The Customer must notify Southwestern by July 1 of this choice, 
to be effective the subsequent calendar year.
2.6.5. Regulation Purchased Adder
    Southwestern has determined the amount of energy used from storage 
to provide Regulation and Frequency Response Service in order to meet 
Southwestern's Balancing Authority Area requirements. The replacement 
value of such energy used shall be recovered through the Regulation 
Purchased Adder. The Regulation Purchased Adder during the time period 
of January 1 through December 31 of the current calendar year is based 
on the average annual use of energy from storage \1\ for Regulation and 
Frequency

[[Page 51153]]

Response Service and Southwestern's estimated purchased power price for 
the corresponding year from the most currently approved Power Repayment 
Studies.
---------------------------------------------------------------------------

    \1\ The average annual use of energy from storage for Regulation 
and Frequency Response Service is based on Southwestern studies.
---------------------------------------------------------------------------

    The Regulation Purchased Adder will be phased in over a period of 
four (4) years as follows:

------------------------------------------------------------------------
                                          Regulation Purchased Adder for
                                            the incremental replacement
                  Year                       value of energy used from
                                                      storage
------------------------------------------------------------------------
2014....................................  \1/4\ of the average annual
                                           use of energy from storage x

                                           price.
------------------------------------------------------------------------

2.6.5.1. Applicability of Regulation Purchased Adder
    The replacement value of the estimated annual use of energy from 
storage for Regulation and Frequency Response Service shall be 
recovered by Customers located within Southwestern's Balancing 
Authority Area on a non-coincident peak ratio share basis, divided into 
twelve equal monthly payments, in accordance with the formula in 
Section 2.6.5.2.
    If the Regulation Purchased Adder is determined and applied under 
Southwestern's Rate Schedule P-13, then it shall not be applied here.
2.6.5.2. Procedure for Determining Regulation Purchased Adder
    Unless otherwise specified by contract, the Regulation Purchased 
Adder for an individual Customer shall be based on the following 
formula rate, calculated to include the replacement value of the 
estimated annual use of energy from storage by Southwestern for 
Regulation and Frequency Response Service.

RPA = The Regulation Purchased Adder for an individual Customer per 
month, which is as follows:
[(L Customer / L Total) x RP Total ] / 12

with the factors defined as follows:

L Customer = The sum in MW of the following three 
factors:
    (1) The Customer's highest metered load plus generation used to 
serve the Customer's load that is accounted for through a reduction 
in the Customer's metered load (referred to as `generation behind 
the meter') during the previous calendar year, and
    (2) The Customer's highest rate of Scheduled Exports \2\ during 
the previous calendar year, and
    (3) The Customer's highest rate of Scheduled Imports \2\ during 
the previous calendar year.
---------------------------------------------------------------------------

    \2\ Scheduled Exports and Scheduled Imports are transactions, 
such as sales and purchases respectively, which are in addition to a 
Customer's metered load that contribute to Southwestern's Balancing 
Authority Area need for regulation.
---------------------------------------------------------------------------

LTotal = The sum of all L Customer factors for all 
Customers that were inside Southwestern's Balancing Authority Area 
at the beginning of the previous calendar year in MW.
RP Total = The ``net'' cost in dollars and cents based on 
Southwestern's estimated purchased power price for the corresponding 
year from the most currently approved Power Repayment Studies 
multiplied by the average annual use of energy from storage, as 
provided for in the table in Section 2.6.5, to support 
Southwestern's ability to regulate within its Balancing Authority 
Area. The ``net'' cost in dollars and cents shall be adjusted by 
subtracting the product of the quantity of such average annual use 
of energy from storage in MWh and Southwestern's highest rate in 
dollars per MWh for Supplemental Peaking Energy during the previous 
calendar year.
    For Customers that have aggregated their load, resources, and 
scheduling into a single node by contract within Southwestern's 
Balancing Authority Area, the individual Customer's respective 
Regulation Purchased Adder shall be that Customer's ratio share of the 
Regulation Purchased Adder established for the node. Such ratio share 
shall be determined for the Customer on a non-coincident basis and 
shall be calculated for the Customer from their highest metered load 
plus generation behind the meter.
 2.6.6. Energy Imbalance Service Limitations
    Energy Imbalance Service is authorized for use only within a 
bandwidth of [ballot]1.5 percent of the actual requirements of the load 
at a particular point of delivery, for any hour, compared to the 
resources scheduled to meet such load during such hour. Deviations 
which are greater than [ballot]1.5 percent, but which are less than 
[ballot]2,000 kilowatts, are considered to be within the authorized 
bandwidth. Deviations outside the authorized bandwidth are subject to a 
Capacity Overrun Penalty.
    Energy delivered or received within the authorized bandwidth for 
this service is accounted for as an inadvertent flow and will be netted 
against flows in the future. The inadvertent flow in any given hour 
will only be offset with the flows in the corresponding hour of a day 
in the same category. Unless otherwise specified by contract, the two 
categories of days are weekdays and weekend days/North American 
Electric Reliability Corporation holidays, and this process will result 
in a separate inadvertent accumulation for each hour of the two 
categories of days. The hourly accumulations in the current month will 
be added to the hourly inadvertent balances from the previous month, 
resulting in a month-end balance for each hour.
    The Customer is required to adjust the scheduling of resources in 
such a way as to reduce the accumulation towards zero. It is recognized 
that the inadvertent hourly flows can be both negative and positive, 
and that offsetting flows should deter a significant accumulation of 
inadvertent. Unless otherwise specified by contract, in the event any 
hourly month-end balance exceeds 12 MWhs, the excess will be subject to 
Section 3.1 or Section 3.2 of this Rate Schedule, depending on the 
direction of the accumulation.

3. Non-Federal Transmission/Interconnection Facilities Service 
Penalties, Terms, and Conditions

3.1. Capacity Overrun Penalty

3.1.1. Penalty Charge for Capacity Overrun
    For each hour during which energy flows outside the authorized 
bandwidth, the Customer will be obliged to purchase such energy at the 
following rates:

------------------------------------------------------------------------
                                                             Rate per
              Months associated with charge                  kilowatt
------------------------------------------------------------------------
March, April, May, October, November, December..........           $0.15

[[Page 51154]]

 
January, February, June, July, August, September........            0.30
------------------------------------------------------------------------

3.1.2. Applicability of Capacity Overrun Penalty
    Customers who receive deliveries within Southwestern's Balancing 
Authority Area are obligated to provide resources sufficient to meet 
their loads. Such obligation is not related to the amount of 
transmission capacity that such Customers may have reserved for 
transmission service to a particular load. In the event that a Customer 
underschedules its resources to serve its load, resulting in a 
difference between resources and actual metered load (adjusted for 
transformer losses as applicable) outside the authorized bandwidth for 
Energy Imbalance Service for any hour, then such Customer is subject to 
the Capacity Overrun Penalty.

3.2. Unauthorized Use of Energy Imbalance Service by Overscheduling of 
Resources

    In the event that a Customer schedules greater resources than are 
needed to serve its load, such that energy flows at rates beyond the 
authorized bandwidth for the use of Energy Imbalance Service, 
Southwestern retains such energy at no cost to Southwestern and with no 
obligation to return such energy.

3.3. Power Factor Penalty

3.3.1. Requirements Related to Power Factor
    Any Customer served from facilities owned by or available by 
contract to Southwestern will be required to maintain a power factor of 
not less than 95 percent and will be subject to the following 
provisions.
3.3.2. Determination of Power Factor
    The power factor will be determined for all Demand Periods and 
shall be calculated under the formula:
[GRAPHIC] [TIFF OMITTED] TN14SE21.001

with the factors defined as follows:

PF = The power factor for any Demand Period of the month.
kWh = The total quantity of energy which is delivered during such 
Demand Period to the point of delivery or interconnection in 
accordance with Section 3.3.4.
rkVAh = The total quantity of reactive kilovolt-ampere-hours (kVARs) 
delivered during such Demand Period to the point of delivery or 
interconnection in accordance with Section 3.3.4.
3.3.3. Penalty Charge for Power Factor
    The Customer shall be assessed a penalty for all Demand Periods of 
a month where the power factor is less than 95 percent lagging. For any 
Demand Period during a particular month such penalty shall be in 
accordance with the following formula:

C = D x (0.95 - LPF) x $0.10

with the factors defined as follows:

C = The charge in dollars to be assessed for any particular Demand 
Period of such month that the determination of power factor ``PF'' 
is calculated to be less than 95 percent lagging.
D = The Customer's demand in kilowatts at the point of delivery for 
such Demand Period in which a low power factor was calculated.
LPF = The lagging power factor, if any, determined by the formula 
``PF'' for such Demand Period.

    If C is negative, then C = zero (0).
3.3.4. Applicability of Power Factor Penalty
    The Power Factor Penalty is applicable to radial interconnections 
with the System of Southwestern. The total Power Factor Penalty for any 
month shall be the sum of all charges ``C'' for all Demand Periods of 
such month. No penalty is assessed for leading power factor. 
Southwestern, in its sole judgment and at its sole option, may 
determine whether power factor calculations should be applied to (i) a 
single physical point of delivery, (ii) a combination of physical 
points of delivery where a Customer has a single, electrically 
integrated load, (iii) or interconnections. The general criteria for 
such decision shall be that, given the configuration of the Customer's 
and Southwestern's systems, Southwestern will determine, in its sole 
judgment and at its sole option, whether the power factor calculation 
more accurately assesses the detrimental impact on Southwestern's 
system when the above formula is calculated for a single physical point 
of delivery, a combination of physical points of delivery, or for an 
interconnection as specified by an Interconnection Agreement.
    Southwestern, at its sole option, may reduce or waive Power Factor 
Penalties when, in Southwestern's sole judgment, low power factor 
conditions were not detrimental to the System of Southwestern due to 
particular loading and voltage conditions at the time the power factor 
dropped below 95 percent lagging.

4. Non-Federal Transmission/Interconnection Facilities Service 
Miscellaneous Rates, Terms, and Conditions

4.1. Real Power Losses

    Customers are required to self-provide all Real Power Losses for 
non-Federal energy transmitted by Southwestern on behalf of such 
Customers under the provisions detailed below.
    Real Power Losses are computed as four (4) percent of the total 
amount of non-Federal energy transmitted by Southwestern. The 
Customer's monthly Real Power Losses are computed each month on a 
megawatthour basis as follows:

ML = 0.04 x NFE

with the factors defined as follows:

ML = The total monthly loss energy, rounded to the nearest 
megawatthour, to be scheduled by a Customer for receipt by 
Southwestern for Real Power Losses associated with non-Federal 
energy transmitted on behalf of such Customer; and
NFE = The amount of non-Federal energy that was transmitted by 
Southwestern on behalf of a Customer during a particular month.

    The Customer must schedule or cause to be scheduled to 
Southwestern, Real Power Losses for which it is responsible subject to 
the following conditions:
    4.1.1. The Customer shall schedule and deliver Real Power Losses 
back to Southwestern during the second month after they were incurred 
by Southwestern in the transmission of the Customer's non-Federal power 
and energy over the System of Southwestern unless such Customer has 
accounted for Real Power Losses as part of a metering arrangement with 
Southwestern.
    4.1.2. On or before the twentieth day of each month, Southwestern 
shall determine the amount of non-Federal loss energy it provided on 
behalf of the Customer during the previous month and provide a written 
schedule to the Customer setting forth hour-by-hour the quantities of 
non-Federal energy to be delivered to Southwestern as losses during the 
next month.
    4.1.3. Real Power Losses not delivered to Southwestern by the 
Customer, according to the schedule provided, during the month in which 
such losses

[[Page 51155]]

are due shall be billed by Southwestern to the Customer to adjust the 
end-of-month loss energy balance to zero (0) megawatthours and the 
Customer shall be obliged to purchase such energy at the following 
rates:
