          CHIEF JUSTICE HECHT delivered the opinion of the Court.


          On January 1, 2002, the Public Utilities Regulatory Act (PURA) implemented a competitive

retail market for electricity in the Electric Reliability Council of Texas (ERCOT).1 Each incumbent,

vertically integrated electric utility within the market was required to “unbundle” its business

            See T EX . U TIL . C OD E §§ 39.001(b)(1) (“The legislature finds that it is in the public interest to . . . implement
on January 1, 2002, a competitive retail electric market that allows each retail customer to choose the customer’s provider
of electricity and that encourages full and fair competition among all providers of electricity”), 39.051(b) (providing for
unbundling by January 1, 2002), 39.102(a) (providing for retail customer choice on or after January 1, 2002); see also
id. § 31.002(5) (“‘Electric Reliability Council of Texas’ or ‘ERCOT’ means the area in Texas served by electric utilities,
municipally owned utilities, and electric cooperatives that is not synchronously interconnected with electric utilities
outside the state.”). ERCOT manages about 90% of the state’s electric load, supplying power to some 24 million Texas
customers. Outside ERCOT, Texas retail customers are served by cooperatives or vertically integrated investor-owned
electric utilities subject to regulation; the Public Utility Commission has not certified that any of those areas have met
PURA’s competitive critieria. P U B . U TIL . C O M M ’N O F T EX ., R EPO RT TO TH E 84 TH L EGISLATU RE : S CO PE O F C O M PETITIO N

activities into three separate units2: a power generation company,3 a transmission and distribution

utility (TDU),4 and a retail electric provider (REP).5 Of the three, only TDUs continued to be

regulated by the Public Utilities Commission (PUC).6

          In this case, several parties to a TDU ratemaking proceeding seek judicial review of the

PUC’s order. As the case comes to us, only three issues remain. We hold that:

•         PURA Section 36.351,7 which requires electric utilities to discount charges for service
          provided to state college and university facilities, does not apply to TDUs because they
          provide service to REPs, not to the REPs’ customers;

•         former PURA Section 36.060(a),8 which required an electric utility’s income taxes to be
          computed as though it had filed a consolidated return with a group of its affiliates eligible

to the PUC for proceedings consistent with this opinion.

                                                        I

       Oncor Electric Delivery Co., LLC (“Oncor”) is the largest TDU in Texas and the sixth largest

in the United States. Its 14,600 miles of transmission lines and 102,000 miles of distribution lines

cover 53,300 square miles and reach 7 million consumers in 401 cities and 91 counties within

ERCOT. Before deregulation, Oncor’s system was part of TXU Electric Co., an integrated utility.

       Oncor is regulated by the PUC. In June 2008, Oncor initiated a ratemaking proceeding with

the Commission, its first request for a comprehensive rate increase since deregulation. Oncor

requested a $253 million increase because of the large investment it had made in its system, its

mounting operations costs, and its anticipated need to make capital expenditures. Several parties

intervened. After extensive hearings, the administrative law judges recommended only a $30 million

rate increase. The PUC ultimately approved a $115 million increase.

       Oncor and other parties to the administrative proceeding sued for judicial review and then

appealed to the court of appeals. The disputes have been winnowed to three, and we limit our

discussion to them. The PUC concluded that:

•        PURA does not require Oncor to discount its rates for transmitting and distributing electricity
         purchased by state colleges and universities;

•        PURA does not require that Oncor’s federal income tax expense be calculated as if it had
         filed a consolidated return with its affiliates, and the expense should be determined as if
         Oncor were a stand-alone corporation; and

•        Oncor failed to show that certain municipal franchise charges were reasonable and necessary
         expenses.

The trial court agreed with the PUC on the tax issue but disagreed on the other two. The court of

appeals agreed with the PUC on the discount and franchise fee issues but not on the tax issue.11

         Three petitions for review were filed with this Court:

•        The State of Texas, which has universities in Oncor’s service areas, seeks review of the
         appellate court’s resolution of the discount issue. The State’s petition is opposed by Oncor,
         the PUC, and CenterPoint Energy Houston Electric, LLC, another TDU. Eight state
         universities in CenterPoint’s service area filed an amicus brief in support of the State’s
         petition.12 We refer to the State and its amici as “State Universities”.13

         13
             The governments of the State are unusually divided in this case. The State sued for judicial review in the trial
court in its own name, asserting the consumer interest of its institutions of higher education in the statutory discount. The
State also has an interest in utility ratemaking through its agency, the PUC, which concluded that Oncor is not required
to apply the discount to its rates. The State and the PUC, with their conflicting positions, are both represented by the
Attorney General. The State has since adopted the alias, “State of Texas Agencies and Institutions of Higher Education”,
shortened to “State Agencies”, apparently to more clearly distinguish between the State’s conflicting interests as both
consumer and regulator. But that agnomen suggests that state agencies other than educational institutions have an interest
in the discount, which, as we explain below, is incorrect. Nor is the State’s consumer interest different from the interest
of the amici State Universities. W e think the State and its amici are more clearly designated “State Universities”, by
which we mean all entities claiming the statutory discount.

•         Oncor seeks review of the appellate court’s resolution of the tax issue. Oncor’s petition is
          opposed by the Office of Public Utility Counsel (OPUC);14 municipalities within Oncor’s
          service area, which refer to themselves as “The Steering Committee of Cities Served by
          Oncor” (“Cities”); and the Texas Industrial Energy Consumers (TIEC).

•         Oncor and Cities seek review of the appellate court’s resolution of the franchise fee issue.
          Their petition is opposed by the PUC.

            The PUC did not file a petition for review. Though the PUC asserts that it properly interpreted the statute,
its response argued that the Court need not grant review on this issue because the statute has since been amended.

20-percent reduction of the utility’s base rates that would otherwise be paid under the applicable

tariffed rate.”18

          Section 36.351 was enacted in 1995,19 when, as we noted at the outset, the generation,

transmission, distribution, and sale of electricity were vertically integrated operations of single

utilities fully regulated by the PUC. In 1999, the Legislature passed Senate Bill 720 “to establish

competition in the retail market for electricity beginning January 1, 2002, and ‘to protect the public

interest during the transition’ to competition.”21 Senate Bill 7 unbundled vertically integrated utilities

in ERCOT, mandating that each electric utility separate its business activities into a power

generation company, an REP, and a TDU.22 The statute deregulated power generation companies and

REPs, creating “a competitive retail electric market that allows each retail consumer to choose the

customer’s provider of electricity”.23 But TDUs remained fully regulated by the PUC.24 Under

deregulation, TDUs still deliver electricity directly to the retail consumer’s meter and provide

metering services, but the charges for TDUs’ services are paid by REPs, which in turn charge the

consumer.25

         Senate Bill 7 did not change the text of Section 36.351, but it did redefine “electric utility”

to exclude unbundled power generation companies and REPs, thereby removing them from the

discount requirement.26 Section 63 of Senate Bill 7 suspended this change during the transition to

a competitive market, freezing total rates paid for electricity by state universities covered by Section

36.351 at December 31, 2001 levels until September 1, 2007.27

         When Oncor initiated this ratemaking proceeding in June 2008, Section 63’s freeze had

expired. Oncor contended that the Section 36.351 discount no longer applied to it because it did not,

in the statute’s words, “charge[] for electric service provided to a facility” of any retail customer,

including state universities. Oncor argued that only REPs provide electric service to retail customers.

The State Universities opposed Oncor’s position. The PUC agreed with Oncor. Concluding that

Section 36.351 is ambiguous, the court of appeals deferred to the PUC’s interpretation.28

         We do not agree that Section 36.351 is ambiguous. PURA is quite clear: in deregulated areas

of the state, a TDU “may not sell electricity”;29 only REPs can.30 TDUs cannot charge consumers for

electric service; TDUs charge wholesale tariffed rates set by the PUC to REPs, who in turn charge

customers negotiated, competitive retail rates. It follows that TDUs cannot discount rates to

consumers but only to REPs. But Section 36.351 does not require a discount to REPs. The State

Universities acknowledge that an REP may not have a legal obligation to pass along a TDU’s

discount to consumers but stress that as a practical matter, universities negotiate with REPs for a

straight pass-through of the TDU charges without any mark-up. The point remains that if universities

continue to receive a discount, it is because of negotiation, not because of Section 36.351. REPs’

not charge consumers for electric service.

transmission and distribution of electricity to consumers’ service meters is a provision of electric

service to consumers’ facilities under Section 36.351 because TDUs’ lines connect to meters

installed and maintained by TDUs at each retail consumer’s facilities. But while TDUs do provide

electric service31 —the physical delivery of electricity to consumers’ premises—they provide this

service to REPs. Only REPs can access the electricity delivered by TDUs. Consumers obtain

electricity through the service provided by REPs.

         The State Universities argue that to interpret Section 36.351 as not applying to TDUs in

deregulated areas produces an absurd result: a state university facility in a regulated area of the state

—outside ERCOT, where vertically integrated electric utilities still exist and are subject to Section

36.351—would be entitled to a discount, while a facility in ERCOT would not be. The University

of Texas at El Paso would receive the discount; the University of Texas at Arlington would not. But

we agree with Oncor and the PUC that leaving any discount to negotiation is consistent with the

competitive market under deregulation.

         The PUC argues that the Legislature recognized the Section 36.351 discount would not

survive deregulation and enacted Section 63 of Senate Bill 7 to extend its effect while the market

transitioned to competition. The State Universities counter that Section 63 froze the total rates paid

         31
              Id. § 11.003(19) (“‘Service’ has its broadest and most inclusive meaning. The term includes any act
performed, anything supplied, and any facilities used or supplied by a public utility in the performance of the utility’s
duties . . . to its patrons, employees, other public utilities, an electric cooperative, and the public.”).

by state universities, not merely the discount. But the discount was included in the frozen rates.

Section 63 preserved the discount while capping total rates. Indeed, Section 63 repeatedly referenced

Section 36.351. We think the PUC has the better of the argument.32

         Finally, the State Universities point to PURA Section 36.354 as evidence that Section 36.351

applies to TDUs. Section 36.354 requires electric utilities to discount rates to military bases but only

“in an area where customer choice is not available.”33 Thus, the statute does not apply to TDUs. The

State Universities argue that when the Legislature wanted to exclude TDUs from a discount

provision, it did so explicitly, and no corresponding language appears in Section 36.351. But in

1995, when Section 36.351 was enacted, it was clearly intended to apply to integrated utilities,

including their transmission and distribution operations. Senate Bill 7’s change in the definition of

“electric utility” made Section 36.351, as we have interpreted the provision, inapplicable to TDUs

but for Section 63, which expired by its own terms in 2007. No change in Section 36.351’s text was

needed to remove its application to TDUs. Section 36.354 was not enacted until 2003.34 At that

point, the limitation of its application to areas outside ERCOT, still under regulation, was perfectly

consistent with Section 36.351.



         32
            The State Universities argue that the PUC’s current position is inconsistent with its determination in a 2001
ratemaking case that the TDU was required to discount its rates under Section 36.351. See Pub. Util. Comm’n of Tex.,

case, Section 63 was still in effect.

         The PUC was required to determine Oncor’s projected expenses and set rates35 at a level that

would allow Oncor a reasonable return on its investment.36 One expense was Oncor’s future tax

liability.37 Oncor contended that its tax expense should be determined as if it were a separate

corporation. OPUC, Cities, and TIEC argued that Oncor’s tax liability should be calculated as if it

were included in its parent’s consolidated tax return. The PUC agreed with Oncor. The court of

appeals reversed.38

         Filing a consolidated federal income tax return allows affiliated companies to share losses

and thereby lower their collective tax liability.39 PURA Section 36.060 requires that the tax savings

from filing a consolidated return benefit ratepayers.40 At the time Oncor’s ratemaking proceeding

was pending in the PUC, Section 36.060(a) provided in pertinent part:

         Unless it is shown to the satisfaction of the regulatory authority that it was reasonable
         to choose not to consolidate returns, an electric utility’s income taxes shall be

Oncor argues that it does not meet condition (1).

         Under federal tax law, a parent corporation and certain of its subsidiary corporations are an

affiliated group that is allowed to file a consolidated return.42 When Oncor initiated this proceeding

in June 2008, it was a wholly owned subsidiary of Energy Future Holdings Corporation (EFH).43 In

2007, EFH and its affiliates, including Oncor, filed a consolidated tax return, as EFH’s and Oncor’s

predecessors had done for years. Oncor, because it was wholly owned by EFH, was deemed a

“disregarded” entity and treated as a division of EFH under federal tax law.44 Had Oncor filed

separately, its tax liability would have been $151 million, but EFH’s affiliated group shared

            Before October 2007, Oncor’s predecessor, Texas Utilities (TXU) Electric Delivery Company, was a Texas

operating losses and, as a result, paid no taxes.45 Using 2007 as the test year, and applying Section

36.060(a), Oncor’s projected tax expense was much lower.

         But in November 2008, while this proceeding was still pending in the PUC, EFH sold a

19.96% interest in Oncor to two international investors. At that point, Oncor was a “partnership” for

federal tax purposes,46 and, because it no longer had a single owner, could not be “‘disregarded’ as

an entity separate from its owner.”47 Federal tax law permitted Oncor to elect to be treated as a

corporation,48 which would have allowed Oncor to be included in the affiliated group eligible for

EFH’s consolidated tax return.49 But Oncor did not make that election, and so by default it would




         45
             Oncor did pay EFH $151 million under their tax-sharing agreement, which called for a consolidated federal
income tax filing for all EFH’s affiliates and subsidiaries, but specifically “segregated or ring-fenced” Oncor from the
tax liabilities or benefits of EFH’s affiliates. The agreement provided that, beginning January 1, 2007, Oncor’s income
tax liability would be calculated and paid on a stand-alone basis as if Oncor were a corporation unrelated to EFH and
its affiliates. This agreement, of course, does not control the application of Section 36.060.

be taxed as a partnership and could not be included in EFH’s consolidated tax return.50 The change

did not impact EFH financially. EFH included its income as a partner in Oncor in its consolidated

tax return, offset this income with other losses, and realized the same sort of tax savings as before.

        The PUC determined that:

•       Oncor’s tax expense should not be based on 2007 but on its situation after November 2008;

•       after November 2008, Oncor was no longer a member of a group eligible to file a
        consolidated tax return within the meaning of Section 36.060(a), and therefore that statute
        did not require calculating its tax return as though it were still included in EFH’s
        consolidated tax return; and

•       although Oncor would be taxed as a partnership, its tax expense should be calculated as if
        it were a stand-alone corporation.

The court of appeals held that because Oncor could have elected to be taxed as a corporation, and

there was no impediment to its doing so, it remained a member of an affiliated group eligible to file

a consolidated tax return.51 Therefore, the court concluded, the PUC should have used the 2007 test

year and applied Section 34.060(a).52

        We disagree. Section 36.060(a) very plainly applies only to a utility that “is” a member of

an affiliated group eligible to file a consolidated tax return, not a utility that could be. The court of

appeals was troubled that Oncor could use its change of ownership and federal tax law to give EFH

the savings ratepayers had received when Oncor was included, as a “disregarded” entity, on EFH’s

consolidated tax return. But that concern cannot be used to read Section 36.060(a) contrary to its

plain text. TIEC argues that the statute should apply because Oncor was “eligible” to be part of a

group filing a consolidated tax return. But that misreads the provision. It is the group that must be

eligible to file a consolidated return, not the utility. The utility must be a member of an eligible

group, and after November 2008, Oncor was not.53

         The developments of November 2008 were “known and measurable changes” the PUC was

required to take into account,54 and it correctly interpreted Section 36.060(a). OPUC, Cities, and

TIEC nevertheless argue that the PUC erred in calculating Oncor’s tax expense as if it were a

corporation when it is taxed as a partnership—that is, its income is passed through to its owners, who

bear the tax. For that reason, they insist, Oncor’s tax expense is minimal. We rejected this argument

in Suburban Utility Corp. v. Public Utility Commission of Texas.55 There, we held that a utility

structured as a Subchapter S corporation could include, as reasonable and necessary expenses in a

ratemaking proceeding, the income taxes paid by its shareholders on the utility’s taxable income.56

Citing precedent from the Commission, we explained that income taxes paid by shareholders of a

pass-through entity “are inescapable business outlays and are directly comparable with similar

corporate taxes which would have been imposed if the utility operations had been carried on by a

corporation.”57 Fairness “entitled” the owner of a pass-through entity “to a reasonable cost of service

         The PUC’s determination to calculate Oncor’s tax expense as if it were a corporation was

not arbitrary or capricious.59

        to collect from each electric utility, transmission and distribution utility, municipally owned utility,
        or electric cooperative that uses the municipality’s streets, alleys, or public ways to provide
        distribution service a charge based on each kilowatt hour of electricity delivered by the utility to each
        retail customer whose consuming facility’s point of delivery is located within the municipality’s

        municipality from electric utilities, municipally owned utilities, or electric cooperatives, as
        appropriate, for calendar year 1998 divided by the total kilowatt hours delivered during 1998 by the
        applicable electric utility, municipally owned utility, or electric cooperative to retail customers whose
        consuming facilities’ points of delivery were located within the municipality’s boundaries. The
        compensation a municipality may collect from each electric utility, transmission and distribution
        utility, municipally owned utility, or electric cooperative providing distribution service shall be equal
        to the charge per kilowatt hour determined for 1998 multiplied times the number of kilowatt hours
        delivered within the municipality’s boundaries.

Section 62(a) of Senate Bill 7 added: “Nothing in this Act shall restrict or limit a municipality’s

historical right to control and receive reasonable compensation for use of public streets, alleys,

rights-of-way, or other public property to convey or provide electricity.”

       In its application to the PUC, Oncor proposed to include $253,884,976 of municipal franchise

charges as a reasonable and necessary operating expense. Of this amount, almost $5.7 million was

a 5% increase recently negotiated between Oncor and Cities. The PUC rejected Oncor’s request,

concluding that a utility cannot pay more than the charge set out in Section 33.008(b). In the court

of appeals, the PUC abandoned that position, which is directly contradicted by Section 33.008(f)’s

phrase, “[n]otwithstanding any other provision”. Instead, the PUC argued, citing the language in

subsection (f), that Oncor could include in its expenses a charge described in Section 33.008(f) only

if it proved that the charge was agreed to “on the expiration of a franchise agreement existing on

September 1, 1999”.65 The PUC argued that Oncor failed to meet its burden of proof because there

was less than a scintilla of evidence that Oncor had agreements with the Cities before September 1,

and that these agreements expired thereafter. The court of appeals agreed.66

       But the expiration of a franchise agreement existing on September 1, 1999, cannot be read

as a condition to agreeing to a different charge. If it were, a municipality that had no franchise

agreement with a TDU on that date could never impose a franchise charge in the future. A

municipality with a franchise agreement in effect on that date could renegotiate it only once and

never again afterward. These restrictions would severely limit “a municipality’s historical right to

control and receive reasonable compensation” for the use of public property, in direct contradiction

of Section 62(a) of Senate Bill 7.

       Section 33.008(f) does not restrict renegotiated franchise charges to only those agreed to on

the expiration of franchise agreements existing on September 1, 1999. The provision simply

precludes the inference that Section 33.008(b) is exclusive. Reading the paragraphs of Section

33.008 together, as we must, they confirm that municipalities may continue to impose franchise

charges after competition, that charges per kilowatt hour equal to the average amount charged in

1998 must be considered reasonable and necessary, and that utilities may continue to renegotiate

franchise charges, though they must demonstrate that the charges are reasonable and necessary in

order to pass them along to REPs.

       The court of appeals misinterpreted Section 33.008(f). The PUC’s disallowance of Oncor’s

renegotiated franchise charges was error.

       Accordingly, the judgment of the court of appeals is affirmed in part and reversed in part, and

the case is remanded to the PUC for proceedings consistent with this opinion.
