                              September 27, 2011 Session

 CONSUMER ADVOCATE & PROTECTION DIVISION OF THE OFFICE
       OF THE ATTORNEY GENERAL OF TENNESSEE
                         v.
          TENNESSEE REGULATORY AUTHORITY

                 An Appeal from the Tennessee Regulatory Authority
                                   No. 09-00183

                 No. M2011-00028-COA-R12-CV - Filed May 30, 2012

This is an appeal from an order of the Tennessee Regulatory Authority (“TRA”). The appeal
was filed by the Consumer Advocate and Protection Division of the Office of Tennessee’s
Attorney General. It challenges the TRA’s authority to allow a gas company to recover
attorney fees that were incurred in a proceeding before the TRA that did not involve rate-
making, and the TRA’s authority to order that the attorney fees be recovered from asset
management funds. We conclude that the TRA has the authority to order that such litigation
fees be recovered as any other reasonable and prudent operating expense of the utility, and
that the TRA acted within its authority in ordering that the fees be paid out of asset
management funds. The TRA’s decision, therefore, is affirmed.

Before we outline the facts and proceedings at issue in this appeal, a brief overview of the
parties, terminology, and regulatory framework is helpful to an understanding of the issues
on appeal.

                                        B ACKGROUND

Respondent/Appellee Chattanooga Gas Company (“the Gas Company”) is a corporation
engaged in the business of transporting, distributing, and selling natural gas in Chattanooga
and Cleveland, Tennessee, and in other portions of Hamilton and Bradley Counties as well.
Although the Gas Company is a for-profit corporation, it is also a public utility, and its
operations are subject to the jurisdiction of Respondent/Appellee Tennessee Regulatory
Authority (“TRA”). See Tenn. Code Ann. § 65-4-101, et seq.

Utility customers in the areas served by the Gas Company pay it to provide them with natural
gas via the customers’ monthly bills. The Gas Company’s rates and charges must be set forth
in tariffs filed by the Gas Company with the TRA, and the Gas Company can charge the
customer only the rates and charges that are set forth in a filed and effective tariff. See Tenn.
Code Ann. § 65-5-102; Tenn. Comp. R. & Regs. 1220-4-1-.03. The tariff in this case is a
multipage loose-leaf document “so that changes [can] be made by reprinting and inserting
a single leaf” when the tariff is revised. See Tenn. Comp. R. & Regs. 1220-1-4-.02. Thus,
a customer’s monthly bill reflects the sum of all of the charges that the company is entitled
to charge, as set forth in the tariff.

The two main components of the Gas Company’s monthly bill charges are (1) the cost of
distributing the gas to the consumer, and (2) the cost of the gas commodity itself, which
includes the cost of storing and transporting that commodity to the Gas Company’s
distribution system for available use. The charges for these two components are set forth in
the tariff and regulated by the TRA. However, each component is governed by a different
set of rules. This is explained in more detail below.

                                               -2-
                               The Distribution of Gas – Base Rates

By statute, the Gas Company is permitted to charge a reasonable base rate for the service of
distributing natural gas to the consumer. Tennessee Code Annotated § 65-5-101 gives the
TRA the authority “to fix just and reasonable individual rates, joint rates, tolls, fares, charges
or schedules thereof, as well as commutation, mileage, and other special rates” charged by
any public utility. The utility is permitted to set base rates that allow it to recover its
operating expenses and earn a profit from the consumer from the operation of its business;
in overseeing these base rates, the TRA is required to balance the interests of the utility with
the interests of Tennessee consumers. See Tenn. Am. Water Co. v. Tenn. Reg. Auth., No.
M2009-00553-COA-R12-CV, 2011 WL 334678, at *15 (Tenn. Ct. App. Jan. 28, 2011). On
one hand, the rate approved by the TRA must provide the utility the opportunity to earn a just
and reasonable return on its investment; on the other hand the rate must not be exorbitant,
so as to avoid the exploitation of consumers. See Bluefield Water Works & Improvement
Co. v. Public Serv. Comm’n of the State of West Va., 262 U.S. 679, 690 (1923). “A rate
need only fall within the ‘zone of reasonableness’ . . . that takes into consideration the
interests of both the consumer and the utility.” Tenn. Cable Television Ass’n. v. Tenn. Pub.
Serv. Comm’n, 844 S.W.2d 151, 159 (Tenn. Ct. App. 1992).

If the public utility wants to increase its base rates, because of increased expenses, decreased
revenues, or any other reason, it must file a revised tariff and a petition with the TRA to
revise the existing rates at least thirty days before the effective date of the new rates. Tenn.
Comp. R. & Regs. 1220-4-1-.03 to .06; see Tenn. Code Ann. § 65-5-103.1 The TRA then has
several options. It can simply allow the revised rate to go into effect by taking no action. In
the alternative, the TRA has the authority to suspend the rate increase pending an
investigation into whether the rate increase is just and reasonable. See Tenn. Code Ann. §
65-5-103. The TRA also has the option to convene a contested case and allow interested
parties to intervene in the matter to oppose the rates. If the TRA conducts an investigation
or contested hearing and then authorizes a rate revision other than the one requested by the
public utility, the utility must file a revised tariff that sets out the rates authorized by TRA.
Only after the revised tariff becomes effective can the public utility charge consumers the
increased rates. The revised tariff remains in effect until it is modified. See Tenn. Code
Ann. § 65-5-103; Tenn. Comp. R. & Regs. 1220-4-1-.03 to .06; see also City of Chattanooga
v. Tenn. Reg. Auth., No. M2008-01733-COA-R12-CV, 2010 WL 2867128, at *1 (Tenn. Ct.
App. July 21, 2010). In utility regulatory parlance, a proceeding before the TRA that
involves the setting of base rates is commonly referred to as a “rate case.”

1
 A public utility is prohibited from raising the rates it charges consumers unless it files a petition with the
TRA. See City of Chattanooga v. Tenn. Reg. Auth., No. M2008-01733-COA-R12-CV, 2010 WL 2867128,
at *1 (Tenn. Ct. App. July 21, 2010) (citing Tenn. Code Ann. § 65-5-103).

                                                     -3-
In a rate case, the TRA will generally consider the utility’s revenues and operating expenses
for a given test period. It then uses that information to predict the rate of return that the
revised rate structure will produce in the reasonably foreseeable future. To evaluate the
requested rate, the TRA takes into consideration the estimated effect of predicted revenues,
expenses, and investments. The attorney fees that the public utility reasonably anticipates
will be incurred in the rate case itself are called “litigation expenses” or “Rate Case
Expenses.”2 These litigation expenses are recoverable as any other business expense in the
rate case; that is, the expenses are built into the revised rates. In this way, the TRA permits
the utility to recover from consumers the reasonable and prudent litigation expenses incurred
in the regulatory proceeding through the setting of the utility’s rates going forward. See
Tenn. Am. Water Co. v. Tenn. Reg. Auth., No. M2009-00553-COA-R12-CV, 2011 WL
334678, at *26-27 (Tenn. Ct. App. Jan. 28, 2011). The parties involved in this appeal do not
challenge the authority of the TRA to permit the utility to recover litigation expenses in this
manner in a rate case.3

                                                  Cost of Gas

The other main component of the Gas Company’s monthly charges is the cost of gas. The
Gas Company must purchase gas and have it delivered to its own distribution system at the
level needed to meet the full natural gas supply needs of the consumers.4 See Tenn. Code
Ann. § 65-4-114 & 115. Generally, the cost of gas is charged to consumers on a pass-
through basis. This means that the utility does not earn a profit from the cost of gas; the
consumer pays the wholesale price, or what the utility paid for the gas.5 The cost of gas is
calculated by using the mechanism set forth in the Purchased Gas Adjustment (“PGA”)
Rules, found in Tenn. Comp. R. & Regs. 1220-4-7 of the Rules of the Tennessee Regulatory

2
    As used in this Opinion, the phrase “litigation expenses” includes attorney fees unless otherwise indicated.
3
 As stated by the Consumer Advocate in its appellate brief: “In general, litigation costs in rate cases are
treated similarly to a number of other expenses for which a utility can seek recovery in a rate case, including
such items as wages and salaries, pensions, depreciation, and administrative costs.” Appellant’s Brief at pp.
14-15 (citing Tenn. Am. Water Co., 2011 WL 334678, at *26-27).
4
 The Gas Company has about 62,000 “firm customers.” As defined in the Gas Company’s tariff, “firm
customers” are customers for whom the Gas Company has a firm obligation to supply gas that is not
ordinarily subject to interruption or curtailment.
5
 This is in contrast to the cost of distributing the gas. As noted above, the Gas Company is permitted to earn
a profit in the rate charged to the consumer for the cost of distributing the gas.

                                                        -4-
Authority.6 Under the PGA Rules, the Gas Company is directed to adjust its charges to
recover the cost of gas (which is not included in the utility’s rate base) from consumers
through their monthly bills. The PGA Rules seek to ensure that the Gas Company neither
over-collects nor under-collects gas costs from consumers.7 See PGA Rule 1220-4-7-.02(1)
& 1220-4-7-.03(1)(a)5(iv).

The PGA mechanism for calculating the cost of gas is quite complicated; it involves intricate
formulas that take into consideration fixed gas costs, variable costs, and related charges. The
Purchased Gas Adjustment itself is comprised of three major components: (1) the Gas Charge
Adjustment, (2) the Refund Adjustment, and (3) the Actual Cost Adjustment. The utility is
required to file a variety of PGA tariff sheets related to the PGA calculations.8

Before a utility is permitted to alter the PGA, the utility must file the proposed tariff changes
with the TRA at least thirty days before the effective date. See PGA Rule 1220-4-7-.02(3).
If the TRA does nothing, the revised rates go into effect after expiration of the thirty-day
period. The TRA may instead choose to suspend the proposed changes and set the matter for
a hearing. The PGA Rules recognize that, in some instances, thirty-days’ notice as to the cost
of gas is not feasible, such as when the Gas Company receives less than thirty days’ notice
from its supplier of an increase in price. In such instances, the TRA “may permit the
Company to place rates into effect with shorter advance notice, upon good cause shown.”
PGA Rule 1220-4-7-.02(3).

At least once a year, the utility must file a non-binding gas purchase plan with the TRA. As
provided under the PGA Rules, the TRA Staff audits the annual report and filing. See PGA
Rule 1220-4-7-.05(1). If the TRA does not order a hearing within ninety days of the filing,
the public utility’s gas purchasing practices are deemed prudent. See PGA Rule 1220-4-7-
.05(2).

The Tenn. Comp. R. & Regs. 1220-4-7 and the subsections therein will be cited as “PGA Rule” in this
Opinion.
7
 As stated in the regulations, “The[] Purchased Gas Adjustment (PGA) Rules are intended to permit the
company to recover, in timely fashion, the total cost of gas purchased for delivery to its customers and to
assure that the Company does not over-collect or under-collect Gas Costs from its customers.” PGA Rule
1220-4-7-.02(1).
8
 We need not go into detail about the various PGA tariff sheets required to be filed with the TRA. Suffice
it to say that the PGA tariff sheets are filed with the TRA, and the TRA must approve any changes in these
tariff sheets.

                                  Asset Management Practices

The monthly charges to the Gas Company’s customers are also affected by the Company’s
“asset management” practices, that is, its practices related to gas purchases. The public
utility’s asset management practices are the method by which it ensures that it will have
sufficient natural gas supply available for the consumers.

The Gas Company outsources certain of its asset management tasks to AGL Resources/AGL
Services Company (“AGL Resources”), a natural gas distribution company.9 AGL Resources
personnel, working exclusively for the Gas Company, determine the level of natural gas that
the Gas Company will purchase to fill the needs of its customers. Once the gas is purchased,
the Gas Company sells or assigns its rights to some of its pipeline capacity assets, i.e.
purchased gas, to an asset manager for a fee. The asset manager is then responsible for
managing the purchased gas supply so as to ensure that the Gas Company’s customers have
an adequate amount of gas when they need it. If it is determined that some of the pipeline
capacity assets that have been purchased will not be needed to meet the needs of the Gas
Company’s customers, the asset manager can market the excess assets to other jurisdictions.

In this case, the Gas Company entered into an asset management agreement with a company
affiliated with the Gas Company, asset manager Sequent Energy Management (“Sequent”).
The Gas Company selected Sequent as its asset manager through a competitive Request for
Proposal (“RFP”) process, as required by the Gas Company’s tariff. Under the asset
management agreement, Sequent was responsible for marketing and selling the Gas
Company’s excess assets. The Agreement provides that the profit earned from the non-
jurisdictional sales of such excess assets would be shared equally (50/50) between Sequent
and the Gas Company. The Gas Company would then, in turn, pass its share of the profit
from the asset sales directly to its customers. The Gas Company’s affiliate, Sequent, keeps
its share of any profits. The asset management agreement between the Gas Company and
Sequent required Sequent to pay a minimum annual fee to the Gas Company, regardless of
whether any gains were earned from the sale of assets. The costs associated with Sequent’s
performance of its duties as the Gas Company’s asset manager were to be deducted from
Sequent’s portion of the profits from the asset sales.

Through the Gas Company’s asset management practices, it has been able to return some of
this profit from the sale of excess assets to consumers. For example, over a thirty-nine month

 The Gas Company is a subsidiary of AGL Resources. The Gas Company’s functions of load forecasting,
pipeline transportation capacity, storage service levels, peaking capability requirements, daily supply
resource management, system monitoring, and asset manager compliance are all performed by AGL
Resources employees, who work exclusively for the Gas Company.

period from 2005 to 2008, Gas Company customers received approximately $7.9 million
from the non-jurisdictional sale of its gas supply and capacity assets.

Gas Company customers recover their share of the profits from non-jurisdictional asset sales
through the Interruptible Margin Credit Rider (“IMCR”), which is included in the Gas
Company’s tariff at “Gas Tariff, TRA No. 1, Tenth Revised Sheet No. 48.” The IMCR
provision included in the tariff is not a component of the PGA Rules; rather, it is a tariff
provision unique to the Gas Company. The IMCR provision states that it is “intended to
authorize the Company to recover not more than ninety percent (90%) of the gross profit
margin losses,” and “to authorize the Company to recover not more than fifty percent (50%)
of the gross profit margin that results from transactions with non-jurisdictional Customers
. . . should such transactions be made by the Company.”

The Gas Company is required to file with the TRA an annual report of the negotiated rate
gross profit margin losses and the gross profit margin from non-jurisdictional transactions.10
The IMCR annual report also includes the calculation of the IMCR adjustment factor to be
applied to customers’ bills. The IMCR factor is a separate billing factor, either a credit or
surcharge as applicable. The entire IMCR report, including the accounting for the Gas
Company’s asset management funds and the application of the IMCR factor to the bills of
Gas Company customers, is subject to an annual audit by the TRA Staff.

                                 Rate Case 1 – Docket No. 06-00175

On June 30, 2006, the Gas Company filed a petition with the TRA. Among other things, the
petition sought to increase the Gas Company’s base rate and implement a new rate design
proposal.11 As required, the Gas Company filed the revised tariff with its petition and
requested that the new rate be effective as of January 1, 2007. In the same time period, the
Gas Company filed several other tariffs, all containing the effective date of July 31, 2006.
To consider these matters, the TRA convened a contested case proceeding under Docket No.
06-00175. In this Opinion, Docket No. 06-00175 is referred to as “Rate Case 1.”

In July 2006, on behalf of local consumers, the Petitioner/Appellant Consumer Advocate and
Protection Division of the Office of the Attorney General of Tennessee (“Consumer

Advocate”)12 and Respondent/Appellee Chattanooga Regional Manufacturer’s Association
(individually “the Manufacturer’s Association”) (collectively “Consumer Groups”),13 on
behalf of local consumers, filed petitions to intervene in Rate Case 1. The intervenor
petitions claimed that the increase in revenue and other changes sought by the Gas Company
were not fair, just, or reasonable, and were not in the best interest of the consumer. On July
27, 2006, the TRA entered an order suspending the tariffs, granting the Consumer Groups’
motions to intervene, and establishing a schedule for the proceedings. In addition, the TRA
bifurcated the proceedings into two phases: revenue requirement (Phase I) and rate design
(Phase II).

During the proceedings, the Consumer Groups raised concerns related to the asset
management arrangement between the Gas Company and its affiliate, Sequent. The
Consumer Advocate wanted to examine Sequent’s gas purchase practices and had concerns
about whether Sequent and the Gas Company were purchasing the correct amount of gas
under their gas supply plan. Essentially, the Consumer Groups alleged that the Gas Company
was oversubscribing its capacity assets, that is, purposefully buying too much gas to help its
affiliate Sequent make profits on the sale of the excess, to the detriment of consumers. Those
concerns did not fit neatly into the characterization of either Phase I or Phase II, but the TRA
made a decision to move the issues to Phase II of the proceedings.

On November 20, 2006, the Gas Company and the Consumer Groups filed with the TRA a
“Proposed Settlement Agreement” to resolve the Phase I issues. At a regularly held TRA
Conference held on December 5, 2006, the Settlement Agreement was unanimously
approved by the TRA. This concluded Phase I of the TRA proceedings.

On May 8, 2007, the Gas Company filed a request with TRA to close Phase II of the
proceedings, because the issues that the parties proposed to address in Phase II — energy
conservation, asset management, and capacity release — were being addressed in an existing
docket, Docket No. 06-00298.14 To facilitate its request to close Phase II, the Gas Company

  The Manufacturer’s Association describes itself as a one-hundred-year-old trade association representing
over 250 manufacturers and other businesses supporting, servicing, and associated with the manufacturing

 Some evidence in the record suggests that on February 23, 2007, the Phase II proceedings were suspended
pending a decision that was already before the TRA in a rate case involving Atmos Energy, Docket No. 05-
                                                                                            (continued...)

                                                   -8-
stated that it would withdraw the conservation initiatives it had proposed as part of its
original TRA petition. The Consumer Groups both objected to the closing of Phase II and
expressed concern regarding their opportunity to be heard on the asset management and
capacity release issues. Ultimately, however, the Consumer Groups agreed that Docket No.
06-00298 would provide an acceptable forum for litigation of those issues.

Accordingly, at a regularly scheduled Authority Conference on July 9, 2007, the TRA voted
to approve the Gas Company’s request to close Phase II, and the case was closed by TRA
order entered on December 17, 2007. Because the audit performed in Docket No. 06-00298
had been completed by the time the TRA order was entered, and the introduction of new
issues into that case would likely have created unnecessary delay in the final resolution of
the audit, the TRA decided to form a separate docket to consider the asset management and
capacity release issues raised by the Consumer Groups.15 This separate docket is discussed
below.

                    The Asset Management Docket - Docket No. 07-00224

Accordingly, the TRA opened a new contested case under Docket No. 07-00224 in order to
conduct an “evaluation of [the Gas Company’s] gas purchases and related sharing
incentives.” The Consumer Groups were allowed to intervene in this docket and to
participate in the proceedings.16 On January 15, 2008, the TRA issued an order convening
a contested case. This new docket is referred to herein as “the Asset Management Docket.”

expenses involved in the new docket would not be factored into the setting of rates in Rate

00258, regarding the issue of what was the appropriate forum for the Consumer Advocate to litigate gas
supply costs and asset management practices. The Gas Company filed this motion to close Phase II in Rate
Case 1 because, based on the suspension of the proceedings, there was no activity in the docket.
15
  The record indicates that the parties agreed to the transfer of the asset management issues into a separate
docket to avoid complications that would arise if a final order were not entered in the existing docket within
six months after the filing of the petition. See Tenn. Code Ann. § 65-5-103(a), (b).

 The Manufacturer’s Association indicated that it intended to intervene in this docket, but it apparently
never filed a petition to intervene. Nevertheless, Counsel for the Manufacturer’s Association regularly
participated in the proceedings.

                                                     -9-
Case 1,17 the Gas Company sought to recover those litigation expenses in the context of the
Asset Management Docket. To this end, on February 28, 2008, at the beginning of the
proceedings in the Asset Management Docket, the Gas Company filed a motion to
accumulate and defer its litigation costs for financial accounting and regulatory purposes so
that, in the end, it would be able to recover those costs from consumers in the future if the
TRA determined that the litigation expenses were recoverable. Additionally, the Gas
Company sought “as an ultimate issue in this proceeding to recover the costs incurred in this
contested case proceeding from the ratepayers through the Purchased Gas Adjustment Rule
(‘PGA’), Chapter 1220-4-7.” The Gas Company reasoned: “As all claims to be litigated in
this docket relate to gas and capacity related costs includible in [the Gas Company’s] PGA,
it is proper for [the Gas Company] to recover the costs associated with the litigation in this
contested case proceeding through the PGA.”

The TRA granted the Gas Company’s request to accumulate and defer the litigation costs,
but clarified that “[t]his determination . . . does not address the issue of whether [the Gas
Company] may recover these costs in the future from ratepayers,” and it expressly reserved
that issue for a later date. On March 17, 2008, the TRA entered an order setting the issues
to be decided in the Asset Management Docket. The order expressly included the issue of
whether the Gas Company would be able to recover from ratepayers litigation costs incurred
as a result of its participation in the Asset Management Docket.18

By all accounts, the Asset Management Docket was a “complex, lengthy, and protracted”
adversarial proceeding that lasted some two years. It is not necessary for us to recount the
details of those proceedings. However, we note that the Asset Management Docket
proceedings included a myriad of disputes; the parties participated in four rounds of
discovery, and in the course of discovery, the Gas Company was required to respond to over
two hundred requests for production propounded by the Consumer Groups. The extensive
discovery also resulted in numerous briefings, motions to compel, and status conferences.
At one point during the proceedings, the Consumer Advocate compared itself to a prosecutor
in a criminal proceeding and claimed that the Gas Company was engaging in defense tactics
similar to those of an accused criminal. The Gas Company, on the other hand, described the

 The Gas Company recovered $300,000 in litigation expenses in Rate Case Expenses incurred in in Rate
Case 1 through the setting of the base rates.

  The list of issues to be addressed in the Asset Management Docket was the subject of some debate. The
Consumer Advocate submitted a revised list of the issues it proposed for resolution in the Asset Management
Docket, and the Gas Company filed a response and a motion to dismiss the claims asserted against it by the
Consumer Groups. The TRA denied the Gas Company’s motion to dismiss and set out its own list of issues
to be decided in that docket.

Consumer Advocate’s discovery requests and overall tactics by using phrases such as
“abusive and expensive fishing expedition,” or “witch hunt,” or “wild goose chase.”

On June 22, 2009, prior to the final hearing in the Asset Management case, the Gas Company
filed a motion for clarification relating to issues of accumulated and deferred litigation costs.
The motion asked for instructions from the TRA on the proper time at which the Gas
Company should provide proof concerning the accumulated and deferred legal expenses it
incurred in the proceedings, considering the fact that the Gas Company’s litigation expenses
would extend beyond the final hearing. In the Consumer Advocate’s response, it agreed with
the Gas Company that the litigation costs may extend beyond the close of the final hearing,
and it took the position that the hearing on the merits in the Asset Management case was not
the appropriate time to address the issue of the Gas Company’s litigation expenses. The
Consumer Advocate’s response also stated: “In agreeing to take up this issue after the
hearing, the Consumer Advocate does not waive its right to contest any aspect of the cost
issue, including, but not limited, to amount.” On June 29, 2009, during a pre-hearing
conference, the TRA Hearing Officer agreed with the parties and directed the Gas Company
to file the proof on its litigation costs at the close of the Asset Management case proceeding.
The hearing on the merits was scheduled for July 13, 2009.

On July 8, 2009, prior to the scheduled hearing, the parties jointly filed a Proposed
Settlement Agreement, resolving all issues in the Asset Management Docket. It included an
agreement to permit the Gas Company to recover the legal expenses incurred in the Asset
Management docket. The Proposed Settlement Agreement further provided that the Gas
Company’s litigation expenses “shall be recorded in the Deferred Gas Cost Account and shall
be recovered based on the schedule below through the procedures set forth in the PGA Rules,
subject to submission of such costs to the Authority, the Authority’s determination that such
costs were prudently incurred, and subject to a maximum cap in the amount of $500,000.”

On July 13, 2009, prior to convening the scheduled hearing on the merits, the TRA
considered the parties’ Proposed Settlement Agreement. The TRA voted unanimously to
deny the Proposed Settlement Agreement, finding that it did not set forth a useful process
that could be implemented by the TRA for continuing or future evaluation of the subject
matters it addressed. The TRA also found that the proposed settlement was not in the best
interest of consumers, the parties, or the TRA. After rejecting the Proposed Settlement
Agreement, the TRA commenced the hearing on the merits, and the parties put on their
proof.

At the conclusion of the proof, the TRA ordered the parties to file written post-hearing briefs
within two weeks of their receipt of the transcript of the Asset Management case hearing.
In accordance with the TRA’s previous ruling, the proof submitted pertained only to the Gas

                                              -11-
Company’s asset management and capacity release practices; no proof was submitted
regarding the litigation expenses incurred by the Gas Company in the Asset Management
Docket.

On August 24, 2009, at a regularly scheduled Authority Conference, the TRA found that the
Gas Company had subscribed to an appropriate level of mix of storage, peaking, and
transportation capacity. It determined that, while the Gas Company’s asset mix appeared
reasonable at that time, anticipated changes in customer mix, weather, and usage patterns
necessitated future periodic review by the TRA of the Gas Company’s capacity planning.
The TRA also ordered the Gas Company to submit future management RFPs to the TRA for
approval prior to placing them out for bid. The TRA concluded by ordering that “a triennial
review of capacity planning shall occur beginning in 2012 with the selection of an
independent consultant.” The TRA allowed the parties a fourteen-day period within which
to comment on the TRA’s ruling. The Gas Company and the Consumer Advocate both filed
comments.

During its regularly scheduled Authority Conference on September 21, 2009, the TRA panel
considered the comments filed by the parties. It voted unanimously to review the Gas
Company’s capacity planning in 2013, rather than 2012, with any future review to be
determined upon the conclusion of the 2013 review. The TRA further determined that the
cost of the 2013 review would be borne by the Gas Company, which would then be permitted
to recover the cost through the Actual Cost Adjustment (“ACA”) account of the PGA Rules.

On October 6, 2009, the Gas Company filed with the TRA detailed proof, including
affidavits, of the litigation expenses it incurred in the Asset Management Docket. The Gas
Company contended that, over the course of the two plus years of litigation in the Asset
Management Docket, it incurred litigation expenses totaling approximately $744,743.81.19
On October 23, 2009, the TRA Hearing Officer entered an order setting the issues and time
for filing briefs related to the Gas Company’s recovery of its litigation costs. As the Hearing
Officer had been informed that the parties had reached a partial agreement on the issue of the
Gas Company’s recovery of its litigation expense, the Hearing Officer also ordered the
parties to file their agreement and provide briefs on: (a) the percentage of the total legal
expenses that the Gas Company should be permitted to recover from ratepayers, and (b) the
appropriate amortization period for the recovery of approved litigation costs.

19
  This figure included the cost of outside attorney fees incurred by two law firms that represented the Gas
Company. It did not include the retention of outside experts, because the Gas Company relied on the
expertise of its own AGL Resources employees during discovery and at the hearing. It also did not include
the expenses incurred in the time and travel costs for those employees.

                                                   -12-
On October 28, 2009, the Consumer Advocate filed a Stipulation with the TRA, stipulating
that it did not contest the accuracy of the total billing amounts for the Gas Company’s
litigation expenses, that it did not contest that the work had been performed, and that it
“agreed that the amount of costs allowed to be recovered shall be recovered through the PGA
[Rules].” The parties did not agree about the portion, if any, of those costs the Gas Company
should be allowed to recover from consumers, nor did they agree about the amortization
period for the recovery of any such costs.

Also on October 28, 2009, the Gas Company and the Consumer Advocate filed briefs with
the TRA Panel on the litigation expense issue. The Gas Company asserted that its legal
expenses were incurred prudently in defending Gas Company actions that were ultimately
found to have been performed in compliance with TRA-approved procedures, and that the
expenses were appropriate and reasonable. The Consumer Advocate conceded that the TRA
had the authority to award litigation expenses to the Gas Company.20 The Consumer
Advocate argued, however, that any such award should be no more than one-half of the Gas
Company’s expenses in the Asset Management Docket. The Consumer Advocate contended
that, if the TRA allowed the Gas Company to recover all of the litigation expenses claimed,
“a dangerous precedent would be set for future non-ratemaking dockets.” The Consumer
Advocate noted that the Gas Company offered no statutory authority for the recovery of such
expenses outside of a rate case, but acknowledged that this matter presented a unique
situation:

        [G]iven the unique history of this matter, including extensive discovery filed
        by the Consumer Advocate in an attempt to gather information in this complex
        Docket of first impression, the Consumer Advocate understands that some
        recovery of costs may be appropriate under the circumstances.

                                           ***
        The Consumer Advocate recognizes that this has been a protracted case with
        extensive discovery and involving complex issues, many of first impression,
        therefore some award of costs could be justified.

The Consumer Advocate argued that, regardless, any final decision should take into account
that the TRA ultimately granted some of the relief requested by the Consumer Advocate by
ordering a triennial review of the Gas Company’s asset management program. The

20
  At oral argument before the TRA, the Consumer Advocate clarified its position on the subject: “[T]he
Consumer Advocate maintains it’s in the discretion of the TRA to completely deny Chattanooga Gas’ request
for cost recovery. Meaning that certainly you can order [that it] recover all their costs, some of their costs,
or none of their costs.”

                                                     -13-
Consumer Advocate proposed that any recovery of the Gas Company’s litigation fees should
be spread out over a period of three years to reduce the burden on consumers.

On November 9, 2009, the parties presented oral argument on the litigation expense recovery
issue before the regularly scheduled TRA Authority Conference. At the hearing, the
Consumer Advocate and the Gas Company agreed that any recovery should be through the
PGA mechanism. The TRA took the issue under advisement.

                                 Rate Case 2 – Docket No. 09-00183

Around that time, on November 16, 2009, the Gas Company filed another petition with the
TRA requesting a rate increase and a modification of its rate design.21 This case was
assigned Docket No. 09-00183. Although the TRA panel members are apparently assigned
randomly to a given docket, it so happened that the TRA panel assigned to the docket for this
petition was comprised of the same three Directors who had been assigned to the Asset
Management Docket.22

At a special TRA Conference on this Gas Company petition, held on November 30, 2009,
the TRA panel voted to convene a contested case proceeding, to suspend the tariff for ninety
days, and to appoint a Hearing Officer for the purpose of hearing preliminary matters and
preparing the matter for a contested hearing before the panel. The Consumer Groups were
permitted to intervene in this docket as well for the purpose of opposing the proposed rate
increase. This docket is referred to herein as “Rate Case 2.”

On December 29, 2009, before the TRA addressed the litigation cost recovery issue pending
in the Asset Management Docket, the Manufacturer’s Association filed a motion in Rate
Case 2 “to Combine the Request of Chattanooga Gas for Reimbursement of Legal Fees in
Docket 07-00224 [the Asset Management Docket] with the Request of Chattanooga Gas for
a General Rate Increase in Docket No. 09-00183 [Rate Case 2].” The Manufacturer’s
Association argued that the Gas Company’s request for costs should be transferred to Rate
Case 2, “because (1) the request is for a specific expense, (2) [the Gas Company’s] ratepayers
need to have public notice of this increase, as well as, the opportunity to comment, and (3)
the TRA does not have the statutory authority to award legal fees outside of a rate case
proceeding.”

21
 In that filing, the Gas Company also proposed the implementation of an energy conservation program called
EnergySMART and the adoption of an Alignment and Usage Adjustment revenue decoupling mechanism.
22
     The three Directors were TRA Chair Sara Kyle, Director Eddie Roberson, and Director Mary W. Freeman.

                                                    -14-
The Consumer Advocate filed a response to the motion to combine. The Consumer
Advocate agreed that legal costs could never be awarded by the TRA in a non-rate case,
regardless of the docket in which the costs were incurred. The Consumer Advocate
acknowledged that this position was contrary to its earlier concession that the TRA had the
discretion to award such expenses. The Consumer Advocate explained that, after reviewing
Tennessee authority on the subject, it came to the position that the TRA could not award
litigation costs to the Gas Company in this non-rate case. In response, the Gas Company
argued that all prudent litigation expenses were recoverable, whether incurred in a rate case
or otherwise, and that the Gas Company’s legal fees should be categorized as “gas-related
costs” and collected from ratepayers under the PGA Rules. Those rules permit amounts paid
to a consultant by a local distribution company to be recorded in the Deferred Gas Cost
Account and recovered through a PGA filing. See PGA Rule 1220-4-7-.05(1)(a)(3).

On January 25, 2010, the parties presented oral argument before the TRA Hearing Officer
on the Manufacturer’s Association’s motion to combine. On February 11, 2010, the Hearing
Officer granted the motion and transferred the proceedings related to the Gas Company’s
request to recover litigation expenses from the Asset Management Docket to Rate Case 2.
The Hearing Officer agreed with the Manufacturer’s Association and the Consumer
Advocate that the prudency of the costs incurred should be considered within a rate case and
found that, because Rate Case 2 was ongoing, it was both practical and efficient to combine
the Gas Company’s request for litigation expenses with the issues in that docket. The
Hearing Officer rejected the Gas Company’s position and determined that the legal fees
requested in the Asset Management Docket were not “gas-related costs” and could not be
collected pursuant to the PGA Rules. Rather, he found that utility legal fees and regulatory
expenses were ordinarily evaluated in the context of a rate case, and if considered valid and
prudent, they could be included in a portion of the overall cost of service for recovery
through an increase in the base rate.

Discovery in Rate Case 2 ensued. The Hearing Officer set the matter for a hearing on the
merits before the TRA panel in Nashville.

In April 2010, a three-day hearing on the merits was conducted before the TRA panel in Rate
Case 2.23 The panel heard testimony from several witnesses on behalf of both the Gas
Company and the Consumer Groups.

Regarding the issue of the Asset Management Docket litigation expenses, the Gas Company
submitted the testimony of the director of regulatory affairs of AGL Resources, Archie

     The hearing was conducted on April 12, 13, and 26, 2010.

                                                    -15-
Hickerson (“Mr. Hickerson”).24 Mr. Hickerson testified that litigation expenses are normal
operating costs of the utility and are routinely included in the regulatory expenses that are
incorporated into the cost of service when rates are set. He also asserted that “any cost that
the [Gas Company] incurs in the normal [course] of business, they can ask to and recover
those costs, and the TRA does have the authority to award the recovery of those costs.”

Mr. Hickerson indicated that, although the Asset Management Docket was not a traditional
rate case, the litigation expenses incurred by the Gas Company in that docket were
recoverable pursuant to the NARUC25 Uniform System of Accounts and the FERC 26 Uniform
System of Accounts, adopted by the TRA,27 which provide that “Regulatory Commission
Expenses” include “all expenses . . . incurred by the utility in connection with formal cases
before regulatory commissions or other regulatory bodies.” The NARUC and FERC systems
also provide that such Regulatory Commission Expenses “shall be charged to account 186,
Miscellaneous Deferred Debits, and amortized by charges to this account.” Specifically, the
recoverable expense items included “expense of counsel, solicitors, attorneys, . . . or defense
against petitions or complaints presented to regulatory bodies . . . .” Mr. Hickerson
acknowledged, however, that he was not aware of any prior TRA ruling in which the TRA
had awarded litigation costs in a non-rate case.

Mr. Hickerson testified as to the amount of litigation expenses claimed by the Gas Company
($744,743.81), and stated that the Gas Company had filed proper verification for the
litigation expenses with the TRA. He also said that the Gas Company proposed to recover
these litigation fees via the PGA/ACA mechanism through a temporary rider on the
Company’s tariff over a period of three years.

The Consumer Advocate submitted the testimony of Terry Buckner (“Mr. Buckner”), who
is a Financial Regulatory Analyst in the Office of the Attorney General. Mr. Buckner
testified that the issues addressed in the Asset Management Docket, involving the cost of gas
and asset management, were not those traditionally addressed in rate cases. He asserted that
the TRA does not have authority under Tennessee law to grant a request for recovery of legal
fees in a non-rate case, regardless of the docket number in which the decision is made. Mr.

                                                    -16-
Buckner indicated that he relied on the case of Kingsport Power Company v. Tennessee
Public Service Commission, No. 84-281-II, 1985 WL 1105936 (Tenn. Ct. App. Feb. 5,
1985), in reaching this conclusion. Mr. Buckner also addressed the reasonableness of the
attorney fees claimed by the Gas Company, opining that the litigation expense sought by the
Gas Company was excessive. He pointed out that there had been no evidentiary hearing
regarding whether the Gas Company acted prudently in incurring those fees.

In May 2010, the parties submitted post-hearing briefs. On May 24, 2010, the TRA Panel
convened at a regularly scheduled Authority Conference to consider the post-hearing briefs.
TRA Director Eddie Roberson drafted a recommendation to the panel and submitted it to the
panel in the form of a motion. He recommended that the Gas Company be permitted to
recover all of the Asset Management Docket litigation expenses requested:

       This has been a most contentious issue between the company and the
       Consumer Advocate. . . . I do believe the costs are recoverable since they
       derived from [a rate case]. . . . It was not the company’s or the stockholders’
       decision whether to spin off the asset manager question into a separate docket.
       It was the TRA’s. The process of [the Asset Management Docket] should
       cause all of us to consider the cost of litigation, which in the final analysis is
       a cost to ratepayers, when pursuing regulatory issues. In my mind, the
       question is not whether the legal fees of the company are recoverable but how
       they will be recovered.

At the hearing, the other two panel members, TRA Chair Sara Kyle and Director Mary
Freeman, agreed with the opinion of Director Roberson.

On November 8, 2010, the TRA issued a lengthy order that resolved the issues related to the
Gas Company’s petition in Rate Case 2. The TRA order also granted the Gas Company’s
request to recover the full amount of litigation expenses it incurred in the Asset Management
Docket. Furthermore, it permitted the Gas Company to recover those funds from consumers
by way of the asset management fund. The TRA explained:

       The panel found that [the Gas Company] was required by the Authority to
       participate in [the Asset Management Docket] and did incur the legal expense
       in a complex, lengthy and protracted proceeding. Additionally, the panel
       found that these costs were incurred in litigating the issues stemming from [the
       Gas Company’s] prior rate case docket, [Rate Case 1]. Upon questioning by
       Director Roberson, Mr. Buckner acknowledged that these legal expenses
       would have been an allowable rate case expense in [Rate Case 1] if the asset
       management issue had been litigated within the [Rate Case 1] docket.

                                              -17-
        Therefore, the panel determined that [the Gas Company] should be allowed
        full recovery of the legal costs incurred in [the Asset Management Docket].
        The panel determined that the most equitable method for the Company to
        recover these costs would be from asset management funds. Allowing
        recovery of legal expenses from asset management funds is an appropriate
        accounting treatment for the non-recurring legal expenses and also provides
        the Company a more timely recovery of legal expenses it has already paid.
        The panel determined the recovery of legal expenses should come from the
        consumers’ share of earnings from the asset management fund, rather than
        through a recurring charge on their monthly bill. Thereafter, the panel voted
        unanimously that recovery of legal expenses should be from asset management
        funds.

Thus, the TRA ordered: “The full amount of legal costs from [the Asset Management
Docket] shall be recovered and such recovery shall be from asset management funds.”

The order also reflected the TRA’s decision to allow the Gas Company to recover other
expenses from asset management funds. Specifically, the TRA ordered that “[t]he
Programmable Thermostat measure and funding of $150,000 for Education and Outreach
Programs shall be funded through revenues generated by [the Gas Company’s] asset manager
and be collected through [the Gas Company’s] IMCR tariff.” The TRA also ordered the Gas
Company to pay $20,000 from asset management funds each year for three years for
consumer-oriented research.28

The Consumer Advocate now appeals the TRA’s decision to permit the Gas Company to
recover its litigation expenses incurred in the Asset Management Docket from asset
management funds. Although the Manufacturer’s Association was aligned with the
Consumer Advocate in the proceedings before the TRA, it has changed its alignment on
appeal and has filed an appellate brief in support of the Gas Company and the TRA. On
appeal, the Manufacturer’s Association takes the position that the TRA properly considered
the Gas Company’s request for Asset Management Docket litigation expenses within the
context of a rate case, after proper notice and a hearing, and that the TRA had the authority
to grant the Gas Company’s request. Thus, the Gas Company, the Manufacturer’s

28
  On October 10, 2010, in accordance with the TRA’s May 24, 2010 ruling, AGL Resources, on behalf of
the Gas Company, filed with the TRA a revised IMCR that included this provision: “The Company shall also
recover through this Rider other costs authorized by the Authority.” This sentence was added to the IMCR
to allow the costs specifically approved by the TRA to be included in the IMCR filing, without having to list
each type of cost separately.

Association, and the TRA (collectively “Appellees”) have all submitted appellate briefs in
support of the TRA’s decision.

                    I SSUES ON A PPEAL AND S TANDARD OF R EVIEW

      1. Whether the TRA exceeded its authority when it awarded litigation costs,
      including attorney fees, for the first time in a case where rates were not being
      set?

      2. Whether a docket to evaluate the Gas Company’s asset management
      practices, in which no rates were set, was a rate case?

      3. Whether the TRA exceeded its authority when it ordered that litigation
      costs, including attorney fees, should be recovered through a rule governing
      the cost of gas that does not permit such recovery?

      4. Whether the award of litigation costs, including attorney fees, for the asset
      management docket on the basis that they “stemmed” from a rate case
      constituted retroactive ratemaking, which is prohibited under Tennessee Law?

One who is aggrieved by a final decision of the TRA must file an appeal with the Middle
Division of this Court. Tenn. Code Ann. § 4-5-322(b)(1)(B)(iii) (2011). The standard for
appellate review of a decision of the TRA is set forth in Tennessee Code Annotated § 4-5-
322(h):

      (h) The court may affirm the decision of the agency or remand the case for
      further proceedings. The court may reverse or modify the decision if the rights
      of the petitioner have been prejudiced because the administrative findings,
      inferences, conclusions or decisions are:

             (1) In violation of constitutional or statutory provisions;

             (2) In excess of the statutory authority of the agency;

             (3) Made upon unlawful procedure;

             (4) Arbitrary or capricious or characterized by abuse of
             discretion or clearly unwarranted exercise of discretion; or

                                            -19-
              (5)(A) Unsupported by evidence that is both substantial and
              material in the light of the entire record.

              (B) In determining the substantiality of evidence, the court shall
              take into account whatever in the record fairly detracts from its
              weight, but the court shall not substitute its judgment for that of
              the agency as to the weight of the evidence on questions of fact.

Tenn. Code Ann. § 4-5-322(h). Thus, the review by this Court is for the “very limited
purpose of determining whether the [TRA] has acted arbitrarily, or in excess of its
jurisdiction, or otherwise unlawfully.” CF Indus. v. Tenn. Pub. Serv. Comm’n, 599 S.W.2d
536, 540 (Tenn. 1980) (quoting City of Whitwell v. Fowler, 343 S.W.2d 897, 899 (Tenn.
1961)).

All of the issues raised by the Consumer Advocate in this appeal involve the question of
whether the TRA exceeded its authority or committed other legal error.29 Such issues are
reviewed de novo on the record, affording no presumption of correctness to the trial court’s
TRA’s decisions. See Tenn. Am. Water Co., 2011 WL 334678, at *15 (citing Tenn. Envt’l
Council, Inc. v. Tenn. Water Quality Control Bd., 254 S.W.3d 396, 402 (Tenn. Ct. App.
2007)). Issues involving statutory interpretation are also issues of law, which we review de
novo. Kiser v. Wolfe, 353 S.W.3d 741, 745 (Tenn. 2011).

In interpreting the relevant statutes and regulations, we are guided by familiar rules of
statutory construction:

       The role of this Court in construing statutes is to ascertain and give effect to
       legislative intent. Cronin v. Howe, 906 S.W.2d 910, 912 (Tenn. 1995).
       Whenever possible, legislative intent is to be ascertained from the natural and
       ordinary meaning of the language used, without forced or subtle construction
       that would limit or extend the meaning of the language. Id. We must avoid
       strained constructions which would render portions of the statute inoperative
       or void. State v. Turner, 913 S.W.2d 158, 160 (Tenn. 1995). Instead, we must
       apply a reasonable construction in light of the purposes and objectives of the
       statutory provision. Id.

Consumer Advocate Div. v. Greer, 967 S.W.2d 759, 761 (Tenn. 1998) (hereinafter “Greer”).

is entitled to great weight in determining legislative intent.” Id. (citing Nashville
Mobilphone Co., Inc. v. Atkins, 536 S.W.2d 335, 340 (Tenn. 1976)).

                                          A NALYSIS

                                    Authority of the TRA

Our analysis must be rooted in an understanding of the TRA’s authority. The TRA is a
regulatory agency and, consequently, it may exercise only the authority that is given to it
expressly by statute or which arises by necessary implication from an express grant of
authority. BellSouth Adver. & Pub’g Corp. v. Tenn. Reg. Auth., 79 S.W.3d 506, 512 (Tenn.
2002); Tenn. Public Serv. Comm’n v. So. Ry. Co., 554 S.W.2d 612, 613 (Tenn. 1977). The
Tennessee legislature’s grant of authority to the TRA is broad indeed. By statute, the
General Assembly has explicitly granted the TRA “practically plenary authority over the
utilities within its jurisdiction.” BellSouth Adver. & Publ’g Corp., 79 S.W.3d at 312 (quoting
Tenn. Cable Tele. Ass’n v. Tenn. Pub. Serv. Comm’n, 844 S.W.2d 151, 159 (Tenn.Ct.
App.1992)). The primary statutory grant of authority is found in Tennessee Code Annotated
§ 65-4-104, which gives the TRA “general supervisory and regulatory power, jurisdiction and
control over all public utilities, and also over their property, property rights, facilities, and
franchises, so far as may be necessary for the purpose of carrying out the provisions of this
chapter.” Tenn. Code Ann. § 65-4-104 (2004). Moreover, Tennessee caselaw, in adherence
to statutory mandates, directs the courts to give statutes related to the authority of the TRA
“a liberal construction;” it cautions that “any doubts as to the existence or extent of a power
conferred on the [TRA] . . . shall be resolved in favor of the existence of the power, to the
end that the [TRA] may effectively govern and control the public utilities placed under its
jurisdiction . . . .” Greer, 967 S.W.2d at 761-62 (quoting Tenn. Code Ann. § 65-4-106 (Supp.
1997)).

Specific to the issues in this case, the TRA has been given broad power “to fix just and
reasonable individual rates, joint rates, tolls, fares, charges or schedules thereof, as well as
commutation, mileage, and other special rates . . . .” Tenn. Code Ann. § 65-5-101. The
authority to fix rates has been delegated totally to the TRA:

       The General Assembly intended to leave rate-making to the Commission’s
       technical competence and specialized knowledge. CF Indus. v. Tennessee
       Pub. Serv. Comm’n, 599 S.W.2d 536, 540 (Tenn. 1980). The only limit it
       placed on the Commission was that the rates must be “just and reasonable.”
       Tenn. Code Ann. § 65-5-201. The breadth of the Commission’s authority has
       prompted the Tennessee Supreme Court to characterize rate-making as
       essentially “a value judgment made by the Commission in the exercise of its

                                              -21-
       sound regulatory judgment and discretion.” CF Indus. v. Tennessee Pub.
       Serv. Comm’n, 599 S.W.2d at 542.

Tenn. Cable Television Ass’n v. Tenn. Pub. Serv. Comm’n, 844 S.W.2d 151, 159 (Tenn.
Ct. App. 1992). “The polestar of public utility rate establishment and regulation is the ‘just
and reasonable’ requirement . . . . There is no statutory nor decisional law that specifies any
particular approach that must be followed by the [TRA].” CF Indus., 599 S.W.2d at 542.
The TRA is expected to use its own experience, technical competence, and specialized
knowledge in fixing just and reasonable rates, so the TRA’s actions in setting rates are not
constrained by the record in a given case. Id. “Thus, focusing upon the issues, the [TRA]
decides that which is just and reasonable. This is the litmus test — nothing more, nothing
less.” Id. at 543.

In order for the TRA to exercise its plenary authority to govern public utilities, the General
Assembly has authorized the TRA to “adopt rules governing the procedures prescribed or
authorized,” including “rules of practice before the authority, together with forms and
instructions,” and “rules implementing, interpreting or making specific the various laws
which [the TRA] enforces or administers.” Greer, 967 S.W.2d at 762 (quoting Tenn. Code
Ann. § 65-2-102(1) & (2) (1997 Supp.)). Pursuant to this express statutory authority, the
TRA adopted the PGA Rules, described above, related to the cost of gas. “Generally, rules
and regulations promulgated pursuant to statutory directive and not inconsistent with such
statutes have the force of law.”             Kogan v. Tenn. Bd. of Dentistry, No.

                Authority to Permit the Recovery of Litigation Expenses

In this appeal, the Consumer Advocate argues that the TRA exceeded its authority when it
awarded litigation expenses to the Gas Company. The Consumer Advocate contends that:
(1) the Asset Management Docket was not a “rate case” and, therefore, the rationale that
litigation costs can be awarded in a “rate case” is inapplicable; (2) the award of litigation
expenses in that docket was not made appropriate either because it arose in the context of a
rate case or because it was combined with another rate case; (3) awarding litigation expenses
to a utility in a non-rate case is not authorized by statute or regulation; (4) awarding litigation
expenses to the utility in a non-rate contested case hearing violates the American Rule; and
(5) the award of litigation expenses in this case constituted improper retroactive ratemaking.
We address these issues in turn.

                         The Asset Management Docket – A Rate Case?

To establish the premise for its main argument, the Consumer Advocate first takes the
position that the Asset Management Docket was not a “rate case.” In making this argument,
the Consumer Advocate concedes that the TRA may permit the Gas Company to recover so-
called Rate Case Expenses as part of the TRA’s implied powers arising out of the
legislature’s express grant of authority to the TRA to “fix just and reasonable” rates.30 This
rationale, the Consumer Advocate contends, does not apply here because no rates were set
in the Asset Management Docket. The Consumer Advocate claims that the term “rates” has
a very precise meaning when used in a regulatory context, and that the TRA’s power to fix
rates extends only to the base rate charged for the distribution of gas to the customer, as
established in a rate case. Because the Asset Management Docket was not a rate case, the
Consumer Advocate insists, the TRA was without authority to award litigation expenses to
the Gas Company in that docket.

In response, Appellees claim that we need not decide whether the TRA has authority to
award litigation expenses in a proceeding that is not a “rate case,” because the Asset
Management Docket was, in fact, a rate case.31 They argue that the term “rate” is much
broader than suggested by the Consumer Advocate, and that it includes base rates, charges,
surcharges, gas costs, fees, and any other mechanism that the TRA devises for the recovery
of a utility’s costs from its customers. In fact, the PGA Rules refer to “demand rates” with
respect to gas costs, and to the filing of a “rate change” under the PGA Rules. See Tenn.
Comp. R. & Regs. 1220-4-7-.02(4); 1220-4-7-.03(1)(a)3(i); 1220-4-7-.03(1)(a)5(iv). The
term “rates,” Appellees argue, can also refer to special tariff rates, which have never been
set in the context of rate cases, and the term may also include charges and fees that are in
addition to the rates set in a rate case proceeding. Thus, the Appellees argue, because the
power of the TRA to “fix just and reasonable” rates extends beyond the setting of base rates,
and the resolution of the Asset Management Docket affected the ultimate rates charged to
the consumer, the Asset Management Docket should be considered a “rate case.”

We agree with Appellees that the TRA’s power to “fix just and reasonable” rates extends
beyond setting base rates in a rate case. The statutes make it clear that the TRA has very
broad “general supervisory and regulatory power, jurisdiction and control over all public

30
  There is no statute or regulation that explicitly permits the TRA to include litigation expenses as an
operating expense of the utility in a rate case. Rather, the practice of allowing Rate Case Expenses to be
recovered by the utility has become the accepted “policy and custom” of the TRA. See Tenn. Am. Water
Co., 2011 WL 334678, at *26.
31
  This assertion is directly contrary to the Gas Company’s argument before the TRA, in which it asserted that
“[t]his clearly is not a rate case.”

                                                    -23-
utilities,” and it presides over all types of regulatory matters. See Tenn. Code Ann. § 65-4-
104 (2004). However, from our review of the record, we must conclude that the Asset
Management Docket cannot be characterized as a “rate case” as that term has come to be
understood in the vernacular of utility regulation. It appears that a proceeding before the
TRA is called a “rate case” only if it is one in which base rates are being set, i.e., where the
TRA fixes a base rate that balances the interest of the utility with the public interest and
assures that the rate charged is just and reasonable. In the Asset Management Docket, the
TRA evaluated the Gas Company’s asset management practices to ensure that consumers
were not being exploited; rates were neither proposed nor set.32 Therefore, we cannot accept
Appellees’ contention that the Asset Management Docket can be characterized as a “rate
case” as that term has been understood and used in the context of utility regulation.

Furthermore, we are not persuaded by Appellees’ argument that the TRA’s award of
litigation expenses was authorized because the Asset Management Docket “stemmed” from
a rate case. The asset management issues were raised by the Consumer Advocate in Rate
Case 1, and could have been decided in that docket. However, they were not decided in that
docket. It is undisputed that the estimated litigation expenses incorporated into the rate that
was set in Rate Case 1 did not include fees for the litigation of the asset management issues.33
Instead, the asset management issues were transferred and resolved in their own separate
docket, apart from the setting of base rates.34

Likewise, we decline to accept Appellees’ argument that the award of litigation expenses by
the TRA was authorized because the litigation expenses were awarded “in the context of a
rate case.” After the merits of the asset management issues raised by the Consumer Advocate
were decided, the question of the Gas Company’s litigation expenses was transferred to Rate
Case 2, in part so that the litigation expenses could be decided “in the context of a rate
case.”35 This transfer, however, did not transform the Asset Management Docket into a “rate

32
 In testifying to the TRA, even the Gas Company’s expert agreed that the Asset Management Docket “was
not a traditional rate proceeding by any means, and [the Gas Company] could not reasonably estimate the
cost to be incurred.”
33
 Had the issues been decided in those proceedings, the Gas Company presumably would have increased the
amount of estimated Rate Case Expenses for the docket and would have incorporated those expenses in
proposing a just and reasonable rate.
34
  Neither party challenged the TRA’s authority to transfer the asset management issues into a docket separate
from the rate case.
35
  The Manufacturer’s Association was interested in having the matter transferred into a rate case in order
to give the public notice and an opportunity to be heard on the issue, and because the Manufacturer’s
                                                                                            (continued...)

                                                    -24-
case.” In fact, the issue of whether the Gas Company could recover Asset Management
Docket litigation expenses was presented and decided separately from the rate case issues in
that docket.36 Accordingly, we decline to adopt Appellees’ argument, and we must conclude
that the TRA’s award of the Gas Company’s litigation expenses was not made in a rate case
or in the equivalent of a rate case.

                 Authority to Award Litigation Expenses in A Non-Rate Case

The issue then becomes whether the TRA had the authority to permit the Gas Company to
recover its litigation expenses in a proceeding that was not a “rate case.” The Consumer
Advocate argues that there is no authority, either express or implied, for the TRA to permit
a utility to recover its litigation expenses in a case in which base rates are not being set. It
argues that the award of litigation expenses in this case was “far different” from an award
of normal operating expenses incurred in a rate case, and that no statutory or regulatory
provision exists that permits the Gas Company to recover litigation expenses that it incurred
in a non-rate case. The Consumer Advocate argues that the TRA’s action in permitting the
Gas Company to recover litigation expenses in a non-rate case was a dramatic change in
regulatory practice, and that the TRA must clearly explain the basis of its authority to make
such a change rather than merely relying on its general authority or citing the fact that the
underlying litigation was “complex.” The Consumer Advocate emphasizes that customers’
bills are comprised of only two charges: the cost of delivering the gas, reflected in the base
rate, and the cost of gas, determined by the application of the PGA Rules. Because the Gas
Company’s litigation expenses were not awarded either as an element of the base rate
charged or through the application of the PGA Rules, the Consumer Advocate contends, the
TRA was without authority to award the Gas Company the litigation expenses it incurred in
the Asset Management Docket.

The Appellees approach the issue from a different perspective. They note that the TRA has
been given plenary authority to govern and supervise utilities, and they argue that nothing in
the statutes or the regulations prohibits the TRA from allowing a utility to recover litigation
expenses incurred in a non-rate regulatory proceeding. The Appellees emphasize that this

35
  (...continued)
Association argued that the TRA had no authority to award the Gas Company its litigation expenses unless
it filed a rate case. Because the public was notified, and because the TRA duly considered the issue in a rate
case, the Manufacturer’s Association does not challenge the TRA’s exercise of its discretion in awarding the
Gas Company its just and reasonable litigation expenses incurred in the Asset Management Docket.
36
  As in Rate Case 1, the litigation expenses incurred in Rate Case 2 were incorporated into the just and
reasonable rate that was fixed by the TRA, but the litigation expenses incurred in the Asset Management
Docket were not included.

                                                    -25-
Court must not interfere with a decision by the TRA unless the TRA has clearly exceeded its
authority, and that where there is “any doubt as to the existence or extent of a power
conferred on the [TRA] . . . [such doubt] shall be resolved in favor of the existence of the
power.” Tenn. Code Ann. § 65-4-106. The TRA is clearly authorized to allow a utility to
recover reasonable and prudent operating costs that are necessary to the utility’s provision
of gas to its customers, they argue, and this may include reasonable and prudent regulatory
commission expenses, as that term is defined in the NARUC system of accounting. In
addition, Appellees claim that, if a utility is not permitted to recover reasonable and prudent
regulatory commission expenses incurred in an extraordinary and unusually complex
proceeding, then the rates set by the TRA will end up being confiscatory, because the utility
would have no way of recovering an extraordinary, legitimate cost of doing business. The
Appellees point out that the Gas Company was left no choice but to expend a considerable
amount of time and resources defending against the allegations of the Consumer Advocate
in the Asset Management Docket, allegations which, as it turned out, were based on neither
fact nor credible data.37 Consequently, the TRA had the authority to allow it to recover the
reasonable and prudent regulatory commission expenses in that case.

In support of its argument on appeal, the Consumer Advocate cites Kingsport Power
Company, the case on which Mr. Buckner relied in support of his testimony. In Kingsport
Power, a consumer association intervened in a proceeding before the Public Service
Commission, the predecessor of the TRA.38 After the matter was concluded, the consumer
association filed a request with the Commission to recover the litigation costs it had incurred
in the underlying proceeding, pursuant to the federal Public Utility Regulatory Practices Act
of 1978 (“PURPA”), 16 U.S.C. § 2632. This statute permitted a consumer to seek
reimbursement for attorney fees and other litigation costs from the utility if the consumer
participated in a regulatory hearing and made a “substantial” contribution, in whole or in part,
to the Commission’s decision.39 Kingsport Power, 1985 WL 1105936, at *1. The Public
Service Commission denied the consumer association’s request, stating: “The Commission
has no statutory authority from the Tennessee legislature to award litigation costs to any
party.” Id. It found, however, that the consumer association would have been entitled to its
litigation fees if the Commission had the jurisdiction to award them. The consumer

  The Gas Company notes that the Consumer Advocate withdrew the majority of the evidence supporting
its claims ten days before the final hearing.
38
  The exact nature of the proceeding is unclear, because no record of the regulatory proceeding or evidence
from the trial court was filed with the appeal. Kingsport Power, 1985 WL 1105936, at *1.

 The consumer was permitted to collect these fees by bringing a civil action against the utility in state court
or by requesting an award of costs from the Commission. Kingsport Power, 1985 WL 1105936, at *1.

                                                     -26-
association filed an appeal to have the Public Service Commission’s decision reviewed by
the chancery court.

On appeal, the chancery court in Kingsport Power agreed with the Public Service
Commission, holding that it had no authority to award litigation expenses to the consumer
association. Because the Public Service Commission had no jurisdiction to award the relief
sought, the chancery court held that the consumer association was not “aggrieved” by the
Commission’s decision and, therefore, had no standing to appeal. Id. at *2. The consumer
association appealed to this Court. On appeal, this Court held that the chancery court did not
have subject matter jurisdiction over the appeal from the Public Service Commission’s order,
because “there was no contested case for the court to review, and nothing before the court
below to invoke its jurisdiction.” Id. at *3. Accordingly, the appellate court held that it
lacked subject matter jurisdiction over the appeal, and dismissed the appeal on that basis.
Id.

In the case at bar, the Consumer Advocate relies on the pronouncement by the Public Service
Commission recounted in Kingsport Power, with which the chancery court apparently
agreed, to the effect that the Public Service Commission had no authority to award litigation
costs to any party.40 Id. at *1. After considering Kingsport Power, we must respectfully
conclude that it is inapposite in this case. First, Kingsport Power involved a request for
litigation expenses pursuant to a federal statute not at issue in the case at bar. More
importantly, the substantive issue in Kingsport Power involved the consumer association’s
right to recover litigation expenses from the utility, not the utility’s right to recover its
operating costs from consumers through gas rates. Thus, the statement by the Public Service
Commission on which the Consumer Advocate relies must be viewed in that context. For
these reasons, we find that Kingsport Power does not support the Consumer Advocate’s
position in this appeal.41

Aside from its reliance on Kingsport Power, the Consumer Advocate insists that the TRA
did not have the authority to permit the Gas Company to recover its asset management
litigation expenses, because those expenses were not recovered either through the setting of

40
  The same Public Service Commission order stated: “No Tennessee statute confers on the Commission the
authority to set attorney fees, expert witness fees, and other litigation costs and assess these costs against
the regulated utility.” Kingsport Power, 1985 WL 1105936, at *1 (emphasis added).
41
  Interestingly, in Kingsport Power, the Public Service Commission indicated in its order that, if the utility
had voluntarily paid the consumer group its attorney fees, it would have treated that “expense as an operating
cost of the utility.” This comment seems to indicate that, had the utility been compelled to pay the litigation
expenses of the consumer group under PURPA, the utility would have been able to recover that expense from
its customers in the manner that the Gas Company seeks to recover its litigation costs in the instant case.

                                                     -27-
rates or through the PGA mechanism. The Consumer Advocate cites no authority that limits
the TRA’s authority to these two means of permitting a utility to recover its costs. Appellees,
on the other hand, do not cite any specific statute or regulation authorizing the TRA to award
asset management litigation expenses. Appellees rely instead on the broad general grant of
power to the TRA.

Overall, from our review of the statutes granting authority to the TRA, the regulations, the
caselaw, and the record in this case, we are persuaded that the Appellee’s perspective on the
issues raised on appeal is correct. The authority granted to the TRA in this arena is clearly
intended to be plenary. The onus, then, is on the Consumer Advocate to show a limitation
on that plenary authority given to the TRA, and it has not done so.

Caselaw and other TRA proceedings indicate that the TRA’s authority is not limited as the
Consumer Advocate insists. The power to “fix just and reasonable” rates is certainly one of
the TRA’s primary responsibilities in governing utilities. Indeed, the task of ratemaking has
been delegated totally to the TRA, and the TRA invests much of its resources into the
ratemaking process. See CF Indus., 599 S.W.2d at 542. However, we agree with Appellees
that the power granted by the legislature to the TRA in Section 65-5-101 is not limited to the
setting of base rates. Rather, the statute directs the TRA to “fix just and reasonable
individual rates, joint rates, tolls, fares, charges or schedules thereof, as well as commutation,
mileage, and other special rates . . . .” Tenn. Code Ann. § 65-5-101. The statutory grant of
authority suggests that, while the TRA’s plenary power to supervise and regulate utilities
includes the setting of base rates, its power is not limited to setting base rates. The statute
indicates that the TRA has authority over all rates charged to customers, and that the TRA
must be able to take any actions necessary in those proceedings to effectuate its decisions.
See BellSouth Adver. & Pub’g Corp., 79 S.W.3d at 506.

As explained above, the Gas Company’s asset management practices directly affect the
ultimate charges to the consumer, in that the Gas Company’s profits from the sale of excess
assets are passed on to the consumer, and they affect the reasonableness of the rates set out
in the Gas Company’s tariff through the charges or credits resulting from the IMCR.42 This
is why the underlying issues were raised in a rate case in the first instance – because asset
management practices affect the ultimate rates charged to customers. The fact that the Asset
Management Docket was not a rate case did not strip the TRA of its authority to allow the

42
  As we discuss in more detail in the analysis of the final issue on appeal, the asset management fund
represents profits due to consumers from the Gas Company’s asset management practices; it is not calculated
by reference to the “cost of gas” calculations in the PGA Rules. Therefore, we do not agree with the
Consumer Advocate’s assertion that the TRA lacked authority to allow the Gas Company to recover its
litigation expenses based on the absence of a PGA Rule permitting such recovery.

                                                   -28-
Gas Company to recover its litigation expenses incurred in that docket as a cost of doing
business.

It is undisputed that the TRA had the authority to preside over the Asset Management Docket
and to address the propriety of the Gas Company’s asset management practices. The Gas
Company had little choice but to participate in the Asset Management Docket to defend its
asset management practices against allegations that they were not in the best interest of the
consumer. At the conclusion of the proceedings, the TRA did not find any improper asset
management practices by the Gas Company.43 In fact, after nearly two years of proceedings,
the Consumer Groups withdrew the testimony of the petitioners’ main expert on the subject,
shortly before the final hearing. The TRA considered the approximately $745,000 in
litigation expenses incurred by the Gas Company in defending its asset management practices
to be an unusual, extraordinary expense of the utility that was necessary, reasonable, and
prudent.44 If the TRA were not permitted to allow the Gas Company to recover these and
other reasonable extraordinary operating costs, this would prevent the TRA from fulfilling
its responsibility to ensure that the base rate charged by the utility covers the utility’s
operating expenses and provides a reasonable rate of return. Thus, in order to “fix just and
reasonable” rates, the TRA must have the authority to permit a utility to recover reasonable
and prudent extraordinary expenses.

The parties have not cited a case in which the TRA permitted a utility to recover its litigation
expenses in a non-rate proceeding, and we have not found one. However, other TRA
proceedings show that it is not unusual for the TRA to exercise its authority to permit a utility
to recover one-time, extraordinary costs. For example, in TRA Docket No. 10-00107, In Re:
Petition of Condo Villas of Gatlinburg Association, Inc. d/b/a Foothills Water Properties for
Emergency Relief for Water Rates, Condo Villas requested emergency relief from the TRA.
Condo Villas sought to recover for an unexpected, extraordinary loss of $15,810 caused by
extreme weather conditions that caused a water line to break, and ultimately resulted in the
loss of millions of gallons of water. Condo Villas sought permission from the TRA to assess
a one-time fee of $155 to each of its 102 customers in order to recover this extraordinary
expense. The Consumer Advocate intervened in the proceeding, and a hearing was
conducted. The TRA granted Condo Villas the relief it requested. The TRA observed that,
“for large utilities, changes in expenses are expected and are generally easy for the utility to
absorb until a rate case filing.” However, because Condo Villas was small and could not

43
  The TRA ordered a future review of the Gas Company’s asset management practices, but we do not
interpret this as a finding that any of its practices were improper.
44
     Again, the reasonableness of the litigation expenses is not an issue before this Court.

                                                       -29-
absorb the unexpected expenses at issue, the TRA permitted the one-time assessment it
requested.

In TRA Docket No. 07-00007, Lynwood Utility Corporation filed a petition to increase its
rates. In the course of those proceedings, consumers complained about odors arising from
Lynwood’s wastewater treatment facility. The Consumer Advocate intervened, and the
parties reached a settlement of the rate case. The TRA approved the settlement, but it
directed Lynwood Utility to file a petition to recover the costs associated with the resolution
of the consumers’ odor complaints. Accordingly, the utility filed Docket No. 08-00060, In
Re: Petition of Lynwood Utility Corporation for Approval of a Cost Recovery Mechanism
for Deferred Odor Elimination Costs, to recover those costs. Subsequently, the Consumer
Advocate and the utility reached an agreement about the odor elimination costs recoverable
by the utility. In this proceeding, there is no indication that the Consumer Advocate
questioned the TRA’s authority to defer odor elimination costs and recover those costs in
another docket outside of a rate-setting case.

In Docket No. 07-00081, Petition of Atmos Energy Corporation for Approval of Tariff
Establishing Environmental Cost Recovery Rider (“ECRR”), Atmos Energy sought
permission from the TRA to recover over a period of three years $2.7 million expended to
cleanup specific environmental sites through an ECRR. The Consumer Advocate intervened.
The parties reached an agreement for Atmos Energy to recover $1.65 million over a period
of four years, and the Consumer Advocate consented to the TRA’s approval of an ECRR that
provided for a recovery period of four years. Once again, there is no indication that the
TRA’s authority to permit the utility to recover extraordinary costs through the addition of
a rider to the tariff was challenged in this proceeding.

Of course, none of these regulatory proceedings directly establishes the TRA’s authority to
allow the Gas Company to recover litigation expenses in a non-rate case.45 They do,
however, demonstrate the manner in which the TRA has addressed extraordinary costs in
the past, and that the setting of base rates is not the only proceeding in which a utility has
been allowed to recover costs.46

45
  The Consumer Advocate correctly points out that these cases involved a utility’s request for a charge or
assessment related to providing utility service, not to incurring litigation expenses in a regulatory proceeding.
46
  After granting the TRA broad authority over the governance of utilities, the General Assembly has not
taken legislative action to curtail the exercise of that authority. Legislative silence on the subject can be
interpreted as indicating legislative approval of the status quo. See Purkey v. Am. Home Assurance Co.,
173 S.W.3d 703, 709 (Tenn. Ct. App. 2005) (stating that Legislature is presumed to be aware of state law
and, by its silence, it intended to preserve the status quo).

                                                      -30-
We also find that the NARUC system of accounting gives credence to the Appellees’
argument that regulatory commission expenses may be recovered by a utility if they are
prudent and reasonable. The definition of “regulatory commission expense,” which is
considered an ordinary operating expense, does not differentiate between litigation expenses
incurred in a “rate case” or those incurred in other types of regulatory cases. Rather,
regulatory commission expenses explicitly include “expenses of counsel, solicitors, or
attorneys . . . engaged in the . . . defense against petitions or complaints presented to
regulatory bodies . . . .” This accounting principle does not, of course, authorize a utility to
recover these operating expenses in every case; rather, it reflects an understanding in the
regulated utility industry that these regulatory commission expenses are simply a cost of
doing business. If the TRA deems it to be appropriate to permit the Gas Company to recover
for this cost in a given proceeding, then it has the authority to allow such recovery.

The Consumer Advocate argues that, even if the TRA had the authority to award the Gas
Company its Asset Management Docket litigation expenses, it did not properly exercise its
authority because it did not explain the reason for its decision. It argues that a mere finding
that the docket was “complex” or “protracted” is an insufficient basis on which to make such
an award. We disagree. It is undisputed that the litigation expenses incurred in the Asset
Management Docket proceedings were complex and that the Gas Company was compelled
to participate. The amount of the Gas Company’s litigation expense is not disputed on
appeal. We find that the TRA’s reasons in the record for awarding the Gas Company its
litigation expenses in this case was sufficient, and its actions were not arbitrary or
capricious.47

Given the TRA’s plenary authority to regulate utilities, and the absence of a statute,
regulation, or other authority prohibiting the TRA’s actions, we hold that the TRA had the
authority to permit the Gas Company to recover from its customers the reasonable and
prudent litigation expenses incurred in the Asset Management Docket.48

                                        The American Rule

The Consumer Advocate argues that the TRA’s award of litigation expenses in the Asset
Management Docket violates the American Rule that each party should bear his own legal

47
  This is unlike the situation in Tennessee American Water Co., wherein the final order of the TRA was
“devoid of” reasons for denying half of the rate case expenses requested in that case. See 2011 WL 334678,
at *27.
48
 The Consumer Advocate cites various policy reasons for its argument that the TRA should not have
awarded litigation expenses. Such policy decisions are beyond the authority of this Court to consider.

                                                  -31-
costs absent a contrary contractual or statutory provision. See House v. Estate of
Edmondson, 245 S.W.3d 372, 377 (Tenn. 2008). The American Rule is not at issue in this
case. As explained in our analysis of this Court’s decision in Kingsport Power, the TRA did
not “award” fees to a “prevailing party,” i.e., it did not order the Consumer Groups to pay
anything to the Gas Company.49 Rather, it permitted the utility to recover from its customers
the utility’s reasonable and prudent litigation expenses. This argument is without merit.

                                       Retroactive Ratemaking

The Consumer Advocate argues that the TRA has the power to set base rates only on a going-
forward basis; that is, rates may not be temporary or subject to a retroactive review that
would require, in effect, either a refund by the company or an additional payment by
consumers. See South Central Bell v. Tenn. Pub. Serv. Comm’n, 675 S.W.2d 718 (Tenn.
Ct. App. 1984). The Consumer Advocate claims that, because the TRA awarded litigation
expenses based on the fact that the Asset Management Docket “stemmed” from Rate Case
1, and then allowed the Gas Company to recover litigation expenses from that proceeding
after Rate Case 1 was closed, the TRA in essence allowed the utility to recover a “refund”
from the proceeding. This decision, the Consumer Advocate argues, constituted
impermissible retroactive ratemaking for which the TRA has no authority.

As noted above, the TRA’s authority to allow the Gas Company to recover its Asset
Management Docket litigation expenses was not based on the fact that it “stemmed” from
a rate case. Rather, the TRA had the authority to permit the Gas Company to recover as an
extraordinary operating expense the litigation expenses incurred in the Asset Management
Docket. This argument is likewise without merit.

              Authority to Allow Recovery From Asset Management Funds

The Consumer Advocate argues that the TRA did not have authority to order that the Asset
Management Docket litigation expenses incurred by the Gas Company be paid from asset
management funds, because this method of recovery is accounted for in the PGA Rules, and
the PGA Rules make no provision for the recovery of litigation costs as a part of the cost of
gas. The Consumer Advocate argues that the PGA Rules specifically enumerate the items

49
  The Consumer Advocate further argues that the American Rule is effectively codified in the Uniform
Administrative Procedures Act, which provides that “any party may be advised and represented at the party’s
own expense by counsel” in a contested case. Tenn. Code Ann. § 4-5-325 (emphasis added). Similarly, the
TRA regulations include a provision stating that “[a]ny party to a contested case may be advised and
represented, at the party’s own expense, by a licensed attorney or attorneys.” Tenn. Comp. Rules & Regs
1220-1-2-.04(1). For the same reasons, neither this statute nor this regulation applies to the TRA’s decision
to permit the Gas Company to recover litigation expenses from its customers.

that can be recovered as a part of the cost of gas. See PGA Rule 1220-4-7-.01 (definition of
“gas costs”). It claims that the PGA Rules cannot be altered at the discretion of the TRA, but
can only be changed through a “rulemaking” procedure. Because the Gas Company never
sought to alter or amend the IMCR through a rulemaking procedure, the Consumer Advocate
contends, the TRA in effect “changed a tariff to the detriment of consumers without notice
or a hearing.” For these reasons, the Consumer Advocate argues, the TRA exceeded its
authority when it ordered that the Asset Management Docket litigation expenses be paid out
of asset management funds.

We respectfully disagree. The asset management fund exists because of the Gas Company’s
asset management practices. It represents profits from the sale of gas and does not involve
the cost of gas. We have already held that the TRA was authorized to allow the utility to
recover the legal expenses it incurred in the Asset Management Docket. In its order, the
TRA concluded that the most appropriate means of recovery for the Gas Company would be
from the asset management fund:

           The panel determined that the most equitable method for the Company to
           recover these costs would be from asset management funds. Allowing
           recovery of legal expenses from asset management funds is an appropriate
           accounting treatment for the non-recurring legal expense and also provides the
           Company a more timely recovery of legal expenses it has already paid. The
           panel determined the recovery of legal expenses should come from the
           consumer’s share of earnings from the asset management fund, rather than
           through a recurring charge on their monthly bill. Thereafter, the panel voted
           unanimously that recovery of legal expenses should be from asset management
           funds.

As explained above, the asset management practices are set forth in the IMCR, and
consumers receive the benefit of their share of asset management funds through the
provisions of the IMCR. Although the Consumer Advocate argues that the litigation
expenses awarded must come “through the PGA mechanism,” the reimbursement to the Gas
Company of its litigation expenses will be made before the asset management funds are
processed through the IMCR or the PGA mechanism. The IMCR provides that “gross profit
margin losses shall be recovered from the firm commodity component of gas costs as
determined under the presently effective Purchased Gas Adjustment Provision.” (Emphasis
added). The IMCR does not provide that the asset management funds are part of the PGA
mechanism.50

     We are mindful of Mr. Hickerson’s testimony that the refund would be accounted for under the Actual Cost
                                                                                                (continued...)

                                                      -33-
Moreover, in the TRA’s order, a variety of Gas Company expenses were ordered to be
recovered from asset management funds, including expenses for energy conservation and
education. The Consumer Advocate does not contest the TRA’s authority to order the
recovery of these costs via asset management funds. In the absence of any express limitation
on this exercise of the TRA’s discretion in this way, we conclude that the TRA has the
authority to order that allowable expenses such as the Asset Management Docket litigation
expenses be paid from asset management funds, by virtue of its plenary power to set rates
and govern and regulate utilities. Therefore, we conclude that the TRA did not exceed its
authority in ordering that the extraordinary litigation expenses incurred in defending the Gas
Company’s asset management fund practices be recovered from asset management funds.

                                            C ONCLUSION

The decision of the TRA is affirmed. Costs on appeal are to be taxed to Appellant Consumer
Advocate and Protection Division of the Office of the Attorney General of Tennessee and
its surety, for which execution may issue, if necessary.
