SUPPLEMENTARY INFORMATION:
Notice of Inquiry
September 20, 2007.
1. In this Notice of Inquiry, the Commission is seeking comments on
its policy regarding the in-kind recovery of fuel and lost and
unaccounted-for gas by natural gas pipeline companies. Current policy,
described below, gives pipelines two options for recovering these
costs, and pipelines follow a variety of practices regarding fuel and
lost and unaccounted-for gas. The Commission is seeking comments on
whether it should change its current policy and prescribe a uniform
method for all pipelines to use in recovering these costs.\1\
---------------------------------------------------------------------------
\1\ In this proceeding, the Commission is seeking comments on
several specific proposals for rate recovery of fuel and lost and
unaccounted-for gas, as well as answers to specific questions. It
also should be noted that the Commission has initiated a separate
proceeding in Docket No. RM07-9-000 inquiring about the need for
changes or revisions in the Commission's reporting requirements for
its financial forms including the Form Nos. 2 and 2-A, Annual
Reports of Major and Nonmajor Natural Gas Companies. Assessment of
Information Requirements for FERC Financial Forms, Notice of
Inquiry, FERC Stats & Regs. ] 35,554 (February 15, 2007). The
Commission received a number of comments and suggestions in that
proceeding regarding the adequacy of information reported in the
Form No. 2 concerning gas retained, used for compression, and lost
and unaccounted-for. Accordingly, the reporting requirements related
to gas retained, used for compression, and lost and unaccounted-for
will be addressed in the Notice of Proposed Rulemaking which the
Commission is concurrently issuing in Docket No. RM07-9-000, 120
FERC ] 61,256.
---------------------------------------------------------------------------
I. Current Commission Policy on Fuel Retention
2. Interstate natural gas pipelines frequently require that
customers contribute a small percentage of the volumes of natural gas
tendered for transportation service to provide fuel for compressors and
to make up for lost and unaccounted-for gas.\2\ Each pipeline states
the percentage it retains in its open access tariff. Currently
effective tariff fuel retention rates range from fractions of a percent
to as high as 13 percent.\3\
---------------------------------------------------------------------------
\2\ Some pipelines do not require shippers to contribute in-kind
a portion of the gas tendered to the pipeline for transportation for
the pipeline's use.
\3\ See, e.g., MIGC, Inc., FERC Gas Tariff, First Revised Volume
No. 1, Eleventh Revised Sheet No. 6 (fuel retention percentages up
to 13 percent); Gas Transmission Northwest, FERC Gas Tariff, Third
Revised Volume No. 1-A, Seventh Revised Sheet No. 6 (0.005 percent
fuel retention).
---------------------------------------------------------------------------
3. The Commission established its current policy concerning the in-
kind recovery of fuel and unaccounted-for gas in ANR Pipeline Company
(ANR).\4\ In its January 2005 order in the ANR case,\5\ the Commission
stated that pipelines have two options to recover these costs. The
first option is to establish a fixed fuel retention percentage in a
general section 4 rate case, and leave that percentage unchanged until
the pipeline files its next general section 4 rate case. The second
option allows the pipeline to include in its tariff a mechanism
permitting periodic changes in its fuel retention percentage outside of
a general section 4 rate case, as allowed by section 154.403 of the
Commission's regulations.\6\ ANR held that, if a pipeline chooses the
second option, it must include in its tariff a mechanism to true-up any
over- and under-recoveries of fuel, absent agreement otherwise by all
interested parties.

---------------------------------------------------------------------------
4. In ANR, the Commission explained that its general ratemaking
policy, established in Order No. 436, is that pipelines must design
their rates based on estimated units of service without any type of
true-up mechanism.\7\ This means that the pipeline is at risk for
under-recovery of its costs between rate cases and may retain any over-
recovery. This gives pipelines an incentive both to minimize their
costs and maximize the service they provide. A cost tracker undercuts
these incentives by guaranteeing the pipeline revenues sufficient to
recover its costs regardless of the level of costs or services
provided.
---------------------------------------------------------------------------
\7\ 18 CFR 284.10(c)(2).
---------------------------------------------------------------------------
5. However, as the Commission explained in ANR, it had permitted an
exception to this policy for a few cost items that are subject to
significant changes from year to year and thus are difficult to
predict. Among these cost items is fuel. The Commission explained that
section 154.403 of its regulations permits a pipeline to adjust its
fuel retention percentages in periodic limited section 4 rate filings
pursuant to a methodology set forth in the pipeline's tariff. The
Commission stated that section 154.403 does not expressly require that
pipelines include true-up mechanisms as part of the tariff provision
permitting periodic adjustments to their fuel retention percentages.
Instead, the Commission stated, it had addressed this issue on a case-
by-case basis and required a true-up when the facts of a particular
case so warranted.
6. In ANR, the Commission changed this approach and held that, if a
pipeline wishes to take full advantage of the incentives underlying our
general ratemaking policy with respect to in-kind fuel recovery, then
it can choose the first option which requires establishing a fixed fuel
retention percentage. However, if the pipeline chooses the second
option and tracks its fuel costs, then there must be an assurance that
the fuel costs are tracked accurately so that the pipeline does not
over-recover its fuel costs under any
[[Page 55763]]
circumstances. Therefore, the second option requires a true-up
mechanism. The Commission explained that allowing a particular cost
item to be tracked gives the pipeline the opportunity to increase that
cost item without regard to the possibility of any offsetting cost
reductions. The Commission stated that in return for this opportunity,
there should be an assurance that the individual cost item is tracked
accurately, and the pipeline should not in any circumstances be
permitted to over-recover those costs.
7. In reaching this conclusion, the Commission rejected ANR's
contention that it should be permitted to retain its existing tracker
without a true-up mechanism because the existing tracker provided it
with an incentive to reduce fuel costs and a true-up mechanism would
eliminate this incentive. ANR argued that because its fuel recovery
mechanism bases each year's fuel retention percentage on the average of
fuel use on its system during the three preceding years, ANR was able
to retain a portion of any over-recoveries of fuel resulting from a
downward trend in fuel use and, on the other hand, must absorb a
portion of any under-recoveries if fuel use trends upward. ANR argued
that with this tracker in place, it had in fact reduced its fuel use
which resulted in savings to its customers.
8. The Commission rejected ANR's argument, stating that allowing
ANR to over-recover fuel from its customers is not a necessary
incentive to encourage the company to minimize its use of fuel gas. The
Commission concluded, with regard to fuel use and lost and unaccounted-
for gas, that the benefits of requiring a true-up outweigh any
disadvantages.
9. While ANR established a general policy of requiring pipelines
such as ANR that have a fuel tracker to include true-up mechanisms, the
Commission has only enforced that policy in individual cases where
parties raise the issue. Thus, pipelines continue to follow a variety
of practices regarding fuel and lost and unaccounted-for gas which can
be described as fitting into one of three categories.
The first category is the stated-rate approach, where a
fixed percentage is stated in the tariff as a non-negotiable fee-in-
kind retained from the volumes tendered for shipment by each shipper
and changed only in a general section 4 rate case. Of 70 major
pipelines, 24 have a stated rate.\8\
---------------------------------------------------------------------------
\8\ These categories and the number of pipelines noted within
each category were identified in a Commission staff analysis of the
FERC tariffs of 70 major pipelines.
---------------------------------------------------------------------------
The second category is the tracker approach, where
provisions in a pipeline's tariff allow the pipeline to make
prospective adjustments to its fuel retention rates from time-to-time,
but do not include a mechanism to allow the pipeline to reconcile past
over-or under-recoveries of fuel. Eight pipelines have tracker
mechanisms without true-up requirements.
The third category is the tracker with a true-up approach,
where provisions in a pipeline's tariff allow for periodic adjustments
to its fuel retention rates, and also provide for a true-up of past
over- and under-recoveries of fuel and lost and unaccounted-for gas.
Thirty-eight pipelines have tracker mechanisms with true-ups in their
tariffs.
II. Discussion
10. Pipeline customers have expressed concerns that in-kind gas
retained by pipelines for fuel and unaccounted-for gas requirements is
excessive, and provides pipelines with significant profits. For
example, the Natural Gas Supply Association, in its recent study of
pipeline returns, estimated that in aggregate 32 pipelines,
representing 80 percent of interstate throughput, generated about $2.1
billion in excess retained fuel over the five-year period ending in
2005.\9\ In a recent complaint against National Fuel Gas Supply
Corporation, the principal concern was excessive fuel retention.\10\

---------------------------------------------------------------------------
11. The Commission's review of information filed by pipelines in
their 2005 Form No. 2 filings indicates that major pipelines appear to
have retained or carried over in their accounts a net sum of over 97
Bcf in fuel beyond what was consumed, lost, or unaccounted-for.\11\ At
average 2005 prices, this represents over $711 million in value.\12\ Of
that amount, 58 Bcf, with a value of $427 million, is attributable to
those pipelines that do not have a tracker mechanism in their tariff,
and nearly 39 Bcf, with a value of over $285 million, is attributable
to pipelines with a tracker and no true-up or a tracker with a true-up
mechanism.
---------------------------------------------------------------------------
\11\ Commission staff examined available Form No. 2 data for
2005 to derive the sum of the net fuel retained (the amount received
from shippers minus the amount consumed for operations or lost or
unaccounted-for).
\12\ The Energy Information Administration (EIA) reports the
average wellhead price of natural gas for 2005 was $7.33 per MMBtu.
(http://tonto.eia.doe.gov/dnav/ng/ng_sum_lsum_dcu_nus_a.htm).
---------------------------------------------------------------------------
12. Moreover, with the tightening in natural gas supplies in recent
years, there have been substantial increases in the price of natural
gas. As a result, the pipeline's fuel charges now make up a
significantly greater percentage of the overall cost of transporting
natural gas.\13\
---------------------------------------------------------------------------
\13\ A comparison between 2002 and 2006 data for Texas Eastern
Transmission Corporation (Texas Eastern) illustrates this point.
According to EIA, the average wellhead natural gas price rose from
$2.95 per MMBtu in 2002, to $6.42 per MMBtu in 2006. Texas Eastern's
maximum rate for interruptible transportation through the full
length of the system (Zone STX to Zone M3) in 2002 was $0.6639 per
MMBtu, and Texas Eastern retained 8.94 percent of the gas for fuel
use, at an additional cost to the shipper of $0.2637 (fuel retention
rate times the wellhead price). FERC Gas Tariff, Seventh Revised
Volume No. 1, Seventh Revised Sheet No. 49. Thus, the shipper's
total cost was $0.9276 per MMBtu. The fuel cost equaled 28.4 percent
of the total. In 2006, the maximum rate for interruptible
transportation was $0.6231, and Texas Eastern retained 7.94 percent
of the gas for fuel, at an additional cost to the shipper of
$0.5097. FERC Gas Tariff, Seventh Revised Volume No. 1, Thirty-
Second Revised Sheet No. 49. Thus, in 2006, the shipper's total cost
was $1.1328 per MMBtu. Here, the fuel cost equaled 45 percent of the
total, an increase of about 17 percentage points over the 2002
figure.
---------------------------------------------------------------------------
13. The increasing significance of pipeline fuel charges in the
overall cost of transportation and the concerns about pipeline cost
over-recoveries suggest that further investigation of in-kind fuel
retention practices is warranted. Therefore, the Commission is seeking
comments on whether its current policy with regard to the in-kind
recovery of fuel and unaccounted for gas should be modified, both for
the purpose of providing pipelines a greater incentive to reduce their
fuel use and lost gas and for the purpose of minimizing pipeline over-
recoveries of these costs. Specifically the Commission is requesting
comments on the following questions:
(1) Should the Commission Continue to Allow Recovery of Pipeline Fuel
Costs Through Fixed Fuel Retention Percentages?
14. As described above, the Commission's review of pipeline Form
No. 2 data indicates that some pipelines, particularly those with fixed
fuel retention percentages, are over-recovering their fuel costs. By
contrast, a properly designed fuel tracker and true-up mechanism would
ensure that a pipeline does not over-recover its fuel costs. However,
allowing pipelines to establish a fixed in-kind fuel retention
percentage in a general section 4 rate case is consistent with the
Commission's general ratemaking
[[Page 55764]]
policies and section 154.403 of the Commission's regulations. In ANR,
the Commission continued to permit pipelines to use that recovery
method, stating that the method gives pipelines an incentive to
minimize their fuel use through more efficient operations. These
efficiencies could benefit customers when the pipeline files its next
general section 4 rate case, although until the pipeline does file a
new section 4 rate case it would retain the benefit from any savings.
Also, a fixed in-kind fuel retention percentage avoids potentially
disruptive changes in the pipeline's fuel rates outside a general
section 4 rate case, thereby giving customers the benefit of greater
certainty as to the pipeline's fuel rates. For that reason, shippers
may favor fixed fuel retention percentages.
15. Do the benefits of a fixed retention percentage for recovery of
fuel in-kind outweigh the potential for cost over-recovery? Have
pipelines with fixed retention percentages reduced their fuel use? If
so, provide specific examples. Have pipelines with fixed in-kind
retention percentages that have reduced their fuel use filed section 4
rate cases, thereby passing through to customers the benefit of any
prospective fuel cost savings? Do pipelines with fixed fuel retention
percentages have less incentive to file new section 4 rate cases, such
that shippers are not receiving the benefit of any reduced fuel use?
Are there barriers that make it difficult for shippers to file section
5 complaints to police over-recovery of fuel costs?
Does the benefit to shippers of greater rate certainty from a fixed
fuel percentage justify continuing to permit pipelines to use a fixed
fuel retention rate? If pipelines were to be allowed to continue using
the fixed fuel retention rate approach, should the Commission consider
imposing explicit incentive requirements, such as the application of an
RPI-X methodology \14\ on either a generic or case-specific basis? If
the Commission were to adopt incentive provisions to encourage
pipelines to reduce fuel use and lost and unaccounted-for gas, should
the Commission adopt a standardized incentive approach, such as the
sharing between the pipeline and its shippers of any fuel cost over-
recoveries and/or under-recoveries? If so, which standardized incentive
approach should the Commission consider?
---------------------------------------------------------------------------
\14\ An ``RPI-X'' methodology would allow fuel costs to rise
with inflation minus some X-factor deduction to provide a strong
incentive towards efficiency and an implicit sharing of future
efficiencies with ratepayers. Such methods, if employed in fuel
retention provisions, would need to be adapted to fit the
circumstances of in-kind retention requirements, rather than
monetary payments.
---------------------------------------------------------------------------
16. New compressor stations can be designed to minimize fuel use
through, for example, motor selection (size, fuel efficiency,
throughput flexibility) as well as minimizing pressure drops through
the station (yard pipe and facility sizing). Existing compressors
stations can also be redesigned to reduce fuel by minimizing pressure
drops through the station or installing gas coolers to reduce the need
for compression. How does the type of fuel cost recovery mechanism
(fixed fuel retention percentages, tracker with no true-up or tracker
with true-up) affect these decisions, if any? Similarly, is the fuel
cost recovery or other mechanism a factor when deciding whether to
construct a larger diameter pipe instead of compression or use advanced
SCADA/control systems to manage line pack?
17. As stated above, if the Commission were to adopt incentive
provisions to encourage pipelines to reduce fuel use and lost and
unaccounted-for gas, one option would be a mechanism for sharing
between the pipeline and its shippers of any fuel cost recoveries and/
or under-recoveries. How could such a cost-and-benefit-sharing
mechanism affect the decisions discussed immediately above? Could a
cost-and-benefit-sharing mechanism between the pipeline and its
customers ameliorate any concerns that fuel efficient investment is
``gold plating'' rate base, i.e., making an investment that increases
the rate base and the corresponding return without necessarily creating
a corresponding benefit to the pipeline's customers?
18. What are the barriers to cost effective, fuel efficient
investment, it any? If barriers exist, how does the Commission remove
such barriers? What factors, including, if applicable, the type of fuel
cost recovery mechanism, affect the amount of research and development
(R&D) being done to advance technology in these areas? How could a
cost-and-benefit-sharing mechanism between the pipeline and its
customers affect the level of R&D? Could fuel efficiency measures
impact either directly or indirectly throughput or reliability on the
pipeline grid, and if so, in what manner?
19. Some fixed fuel retention provisions were established through
settlements. How important are fixed fuel retention provisions to these
settlements? If the Commission adopts a new generic policy, should it
modify these existing settlements to apply its new policy? If the
Commission adopts a generic fuel retention policy, should it permit
pipelines and shippers to reach settlements thereafter that provide for
recovery of fuel costs in a manner different from that policy?
(2) Should the Commission Mandate That All Pipelines Must Have a
Tracker Mechanism for the Recovery of Fuel?
20. While the Commission's general policy is that rates should be
based on projections of future costs based on test period experience,
the Commission permits certain costs that are volatile and thus
particularly difficult to project, to be tracked. Is fuel use and lost
and unaccounted-for gas difficult to predict with precision? If so,
does the volatility of pipeline fuel use and the experience with the
fixed retention percentage justify a blanket requirement that all
pipelines recover their fuel costs through a tracker? If not, should
the Commission continue the exception that permits pipelines to make
limited section 4 filings tracking their fuel costs? Do the recent
increases in the cost of fuel further justify use of a tracker?
21. In Order No. 637, the Commission established a principle that
pipelines should not profit from the penalty provisions in their
tariffs for imbalances, unauthorized overruns, scheduling violations,
etc.\15\ This was intended to eliminate any incentive for pipelines to
propose unnecessary penalties that hinder efficiency.\16\ Does
permitting pipelines to profit from fuel retention also create
undesirable incentives for pipelines? For example, do the profits from
excess fuel retention lead some pipelines to avoid updating their base
tariff rates because, on balance, they are receiving an adequate cash
flow in aggregate?

---------------------------------------------------------------------------
(3) If the Commission Requires Pipelines To Use a Tracker, Should It
Require a True-Up Mechanism?
As stated above, in ANR, the Commission concluded that if a
pipeline has a tracker and is therefore able to recover its fuel costs
outside of a general section 4 proceeding, it should track those costs
accurately and not be permitted to over-recover its fuel costs in any
circumstances. Accordingly, the Commission required all pipelines with
trackers to include a true-up mechanism. With both a tracker and a
true-up mechanism, the pipeline simply passes through its fuel costs to
its customers, and, therefore, there may in
[[Page 55765]]
fact be little incentive for the pipeline to try to reduce those costs.
22. In ANR, the Commission found that the inclusion of a true-up
mechanism in a tracker does not remove all incentives for the pipeline
to reduce its fuel use. The Commission explained that pipelines do face
some competitive pressures in obtaining marginal throughput, for
example, obtaining customers with access to alternative fuels. Because
the Commission has held that pipelines may not discount their fuel use
percentages since those costs are variable, the only way a pipeline can
reduce its fuel percentages in order to help obtain marginal business
is by reducing its fuel usage.
23. Was the Commission's conclusion in ANR, that the benefits of
requiring a true-up as part of a tracker outweigh the disadvantages of
reduced incentives for efficient operation accurate? What impact does a
true-up mechanism have on a pipeline's incentive to reduce fuel costs?
Is there evidence that pipelines with tracker and true-up mechanisms
operate less efficiently than pipelines without such mechanisms?
24. Is there a benefit to giving pipelines an incentive to reduce
fuel use, such as the inclusion in the tracker of a profit or loss
sharing mechanism? If the pipeline could retain some benefit of fuel
cost reductions, would it have a greater incentive to reduce those
costs? Would customers benefit from the reduced costs and from sharing
in any cost over-recoveries? How important are fuel costs relative to
total transportation costs?
(4) Should the Commission Retain Its Current Policy?
25. Finally, the Commission seeks comments on whether it should
retain its current policy which gives pipeline discretion over whether
to have a tracker mechanism governing the recovery of fuel costs. What
are the benefits and/or costs of retaining the current policy? What
factors should the Commission consider in deciding whether a change in
fuel retention policy is warranted at this time?
