FROM THE DISTRICT COURTS OF TRAVIS COUNTY, 201ST & 98TH JUDICIAL DISTRICTS
NOS. GV2-00906 & GN2-01289, HONORABLE SCOTT H. JENKINS, JUDGE PRESIDING


O P I N I O N


	In 1999, the Texas Legislature amended the Public Utility Regulatory Act,
restructuring and partially deregulating the electric industry in Texas.  See Act of May 27, 1999, 76th
Leg., R.S., ch. 405, 1999 Tex. Gen. Laws 2543, 2543-2625 (codified at Tex. Util. Code Ann.
§§ 39.001-.910 (West Supp. 2004-05)) ("PURA").  As part of restructuring, electric utility
companies were required to "unbundle" into three distinct entities: (1) a power generation company,
(2) a transmission and distribution company, and (3) a retail electric provider ("REP").  PURA
§ 39.051.  Some unbundled units were independent, and others remained affiliated with the electric
utility.  City of Corpus Christi v. Public Util. Comm'n, 51 S.W.3d 231, 237 (Tex. 2001).  Affiliated
REPs were required, beginning January 1, 2002, to sell electricity to residential and small
commercial customers at a discounted rate called the price to beat ("PTB").  PURA § 39.202(a).  The
PTB was to be set by the Public Utility Commission ("Commission") at "six percent less than the
affiliated electric utility's corresponding average residential and small commercial rates . . . in effect
on January 1, 1999, adjusted to reflect the fuel factor."  Id.
	This appeal concerns the process of approving the fuel factor component of the PTB. 
See id. § 39.202 (a), (b).  The main issues on appeal are whether the expenses sought by electric
utilities Central Power & Light Company ("CPL") and West Texas Utility Company ("WTU"), (1) 
were "reasonable" estimates of "eligible" projected fuel expenses, and whether procedural
irregularities tainted the fuel factor determinations.  See City of El Paso v. El Paso Elec. Co., 851
S.W.2d 896, 897-98 (Tex. App.--Austin 1993, writ denied). (2)
  After a contested-case hearing in
which the eligibility and the reasonableness of portions of CPL's and WTU's expenses were
questioned, the Commission approved the disputed expenses and included them in the fuel factor
component of the PTB.  On appeal, the district court affirmed the Commission's decision in part and
reversed it in part.  We will affirm in part and reverse in part the district court's judgment.

BACKGROUND

	The Commission set the PTB affiliated retail electric providers must charge to certain
classes of customers to protect residential and small commercial customers from adverse impacts
of competition in the transition to deregulation.  The PTB is the base rate of the utility as modified
by a "fixed fuel factor," an adjustment accounting for changes in fuel prices.  Cities of Alvin v. Public
Util. Comm'n, 143 S.W.3d 872, 875 (Tex. App.--Austin 2004, no pet.).  Fuel factors are calculated
by dividing the electric utility's projected net eligible fuel expenses (3) by the corresponding projected
kilowatt-hour sales for the period in which the fuel factors are expected to be in effect.  16 Tex.
Admin. Code § 25.237(a)(1) (2005).  The expenses recovered through the fuel factor are reasonable
estimates of the electric utility's eligible fuel expenses during the period that the fuel factor is
expected to be in effect. Id. § 25.237(c)(1)(A).
	The process of setting the fuel-factor component of CPL's and WTU's initial PTB
rate began with their applications to the Commission seeking approval of their projected fuel
expenses.  See Tex. Pub. Util. Comm'n, Application of Central Power and Light Company to
Implement the Fuel Fact Component of the Price to Beat Rates, Docket No. 24195 (June 5, 2001);
Tex. Pub. Util. Comm'n, Application of West Texas Utility Company to Implement the Fuel Factor
Component of the Price to Beat Rates, Docket No. 24335 (July 3, 2001); PURA § 39.202(a), (b); 16
Tex. Admin. Code § 25.41(f)(3)(A) (2005) (application process for PTB).  The Commission referred
both applications to the State Office of Administrative Hearings ("SOAH") for contested-case
hearings.  See PURA § 14.053 (West 1998); Tex. Gov't Code Ann. § 2003.049(b) (West 2000); 16
Tex. Admin. Code § 22.207 (2005).  The purpose of each proceeding was to determine whether the
expenses CPL and WTU sought to recover were eligible and reasonable fuel expenses.  See PURA
§ 36.003(a); 16 Tex. Admin. Code §§ 25.235(a), .237(a) (2005).
 AES New Energy, Inc./The New Power Company (jointly, "New Power") intervened
in support of both applications.  The Office of Public Utility Council ("OPC"), (4) the Steering
Committee of Cities served by CPL ("Steering Committee"), and the Cities of Abilene, San Angelo,
and Vernon ("Cities") intervened in opposition to CPL's and WTU's applications.  OPC, Steering
Committee, and Cities argued that the expenses CPL and WTU would incur under deregulation as
a result of competition were ineligible for inclusion in the fuel factor.  These included the capacity
auction expense, (5) the unaccounted for energy expense ("UFE"), (6) the transmission-congestion-management expense ("TCM"), the qualified scheduling entity expense ("QSE"), (7) and the single
area/multi-area management expense. (8)  OPC, Steering Committee, and Cities also challenged the
reasonableness of CPL's and WTU's included coal, natural gas, and purchased-power costs.  They
contended that because the price for coal, natural gas, and purchased power had dropped significantly
after the initial applications to set the fuel factors, the updated prices should be used to estimate
projected fuel costs.  The Cities opposed WTU's request to include railcar depreciation expenses.
	The Commission held all of the disputed expenses eligible for inclusion in the fuel
factors; (9) approved CPL's and WTU's coal, natural gas, and purchased power estimates, finding that
their costs were generally accurate because they were based on existing contracts and not specifically
tied to the market price of natural gas; (10) and approved WTU's railcar-depreciation expense.
	OPC, Steering Committee, and Cities sued the Commission, seeking judicial review
of its decisions. (11)  In CPL's case, the district court reversed the Commission's decision to approve
the capacity-auction expense, finding that the Commission's findings were not supported by
substantial evidence and that in approving the capacity-auction expense the Commission improperly
shifted the burden of proof from the electric utility to the intervenors.  The court affirmed the
Commission's decision in all other respects.  In WTU's case, the district court also reversed the
Commission's decision concerning the capacity-auction expense for lack of substantial evidence and
improper shifting of the burden of proof.  It also reversed the Commission's allowance for UFE
because the Commission's decision was based on the treatment of UFE in other PTB proceedings. 
The Court affirmed the Commission's order in all other respects.  All parties have appealed the
district court's decision, and we have consolidated the appeals. 
	CPL, WTU, the Commission, and New Power appeal the district court's ruling
reversing the Commission's findings regarding the capacity-auction expense.  WTU challenges the
district court's ruling overturning the Commission's decision allowing WTU to recover UFE
expenses.  In both cases, OPC, Steering Committee, and Cities appeal the court's ruling approving
the Commission's decision to allow the disputed expenses.  They also accuse the Commission of
acting arbitrarily and capriciously by excluding testimony concerning the price of natural gas and
affording CPL and WTU preferential treatment in calculating natural gas costs.  Steering Committee
and Cities accuse two Commissioners of engaging in ex parte communications with an Enron
affiliate, New Power, during the pendency of the proceedings and of requesting and receiving
evidence outside the record concerning "headroom."  Steering Committee also alleges that the
Commission erred by relying on non-record facts in approving UFE fees in CPL's case and
challenges the reasonableness of CPL's railcar depreciation expense.

DISCUSSION

Fuel-related expenses
 	The parties' arguments fall into two categories: whether the disputed expenses were
eligible fuel expenses and whether they were reasonable.

Eligibility
	One of the main points of contention in both proceedings was whether CPL and WTU
could recover expenses that would occur only in a deregulated environment.  The disputed expenses
are those relating to the capacity auction, single/multi-area dispatch, QSE, TCM and UFE.  OPC,
Steering Committee, and Cities argue that the fuel factor should be calculated as though the system
of regulation continued, notwithstanding known changes to the marketplace.  This has been referred
to as the "continuing regulation model" and would exclude all expenses arising from deregulation. 
	The Commission contends that it approved each of these expenses because the
traditional method of determining fuel factors requires that "fuel factors be calculated using
reasonable estimates of the electric utility's eligible fuel expense during the period for which the fuel
factor is expected to be in effect," here, the 2002 rate year, and because fuel factors should include
known and measurable expenses that would occur in 2002 after deregulation regardless of whether
those expenses existed before deregulation.  The Commission's decision to approve the disputed
expenses was based on its interpretation of section 39.202(b) and 16 Tex. Admin. Code section
25.41 ("PTB rule").
	The correct construction of section 39.202 is a question of law that we review de
novo.  Texas Dep't of Transp. v. Needham, 82 S.W.3d 314, 318 (Tex. 2002).  In construing a statute,
we determine and implement the legislature's intent.  Liberty Mut. Ins. Co. v. Garrison Contractors,
Inc., 966 S.W.2d 482, 484 (Tex.1998).  We will give weight to the Commission's interpretation of
its own powers if it is reasonable and consistent with the statute.  Cities of Austin, Dallas, Ft. Worth
& Hereford v. Southwestern Bell Tel., 92 S.W.3d 434, 441-42 (Tex. 2002).
 	The Commission's interpretation of its own regulations is entitled to deference by the
courts.  Public Util. Comm'n v. Gulf States Utils. Co., 809 S.W.2d 201, 207 (Tex. 1991).  "Our
review is limited to determining whether the administrative interpretation is plainly erroneous or
inconsistent with the regulation."  Id.  However, if the Commission has failed to follow the clear,
unambiguous language of its own regulation, we must reverse its action as arbitrary and capricious. 
Id.; Power Res. Group, Inc. v. Public Util. Comm'n of Tex., 73 S.W.3d 354, 357 (Tex. App.--Austin
2002, pet. denied).
	PURA section 39.202(b) reads: "The Commission shall determine the fuel factor for
each electric utility as of December 31, 2001."  In adopting its PTB rule, the Commission elaborated: 

The commission agrees that it is critical that the initial price to beat fuel factor be set
as accurately as possible, but disagrees with any assertions that the fuel factor should
reflect anything other than the historic fuel mix of the integrated utility, as this is how
the fuel factor would have been set under continuing regulation (with allowance for
that fuel mix to change as the utility's portfolio changes).


26 Tex. Reg. 2680, 2692 (2001).  It also said:


The commission finds, that as stated in subsection (f)(3)(B), the proper reading of
PURA [Public Utility Regulatory Act] § 39.202(b) is that the final fuel factor should
be set in the traditional manner as outlined by the current fuel rule.  While the
commission recognizes that the inclusion of fuel factor based on historical integrated
utility fuel costs as part of the price to beat appears inconsistent with the market
structure under [Senate Bill] 7, where REPs are prohibited from owning generation,
the commission finds that the price to beat was intended to be calculated from each
utility's regulated rate in effect on January 1, 1999, discounted by 6.0% and updated
for a final fuel factor.  Utility-specific issues are to be addressed in the individual fuel
factor cases, within the confines of this finding.


Id. at 2701.
	The challengers argue that, by authorizing the Commission to determine the fuel
factor for the "electric utility as of December 31, 2001," the legislature intended for the Commission
to approve only the sorts of fuel expenses an integrated "electric utility" would have incurred in a
regulated environment for two reasons: (1) section 39.202(b) uses the term "electric utility," which
does not include a "retail electric provider," and (2) it uses the phrase "as of December 31, 2001,"
the day before deregulation was to commence.  They believe that the Commission's rules support
this reading because they mandate that the fuel factor reflect the historic fuel mix of the integrated
utility, as that is how it would have been set under continuing regulation.
	The Commission now argues, along with the former utilities, that in allowing
expenses for the capacity-auction, UFE, single area/multi-area dispatch, QSE, and TCM costs in the
fuel factor calculation for CPL and WTU, it was permissibly taking into account "known and
measurable" expenses that would necessarily occur in the rate year, 2002, whether or not they
occurred as a result of deregulation. (12)  We must now determine whether the Commission's action
was arbitrary, capricious, or inconsistent with the regulation or statute.  See Gulf States Utils. Co.,
809 S.W.2d at 207; Cities of Austin, Dallas, Ft. Worth & Hereford, 92 S.W.3d at 441-42.
	The Commission argues that it set each of these fuel factors exactly as it would have
set them under a continuing regulation scenario; that is, in considering the disputed expenses, it set
the fuel factor in the traditional manner as outlined in the current fuel rule.  See 26 Tex. Reg. 2680,
2692, 2701.  Traditionally, fuel factors are "calculated using reasonable estimates of the electric
utility's eligible fuel expense during the period in which the fuel factor is expected to be in effect,"
here the 2002 rate year.  16 Tex. Admin. Code §§ 25.237(c)(1)(A) (utility revising fuel factor must
show reasonable estimate for period in effect), 25.41(f)(3)(B) (setting year as 2002).  In its attempt
to set these fuel factors as accurately as possible, the Commission reasoned that it need not ignore
known and measurable events that would occur in the 2002 rate year. (13)  It calculated the fuel factors
using reasonable estimates of actual expenses during the period in which the fuel factors would be
in effect.  This interpretation is not plainly erroneous or inconsistent with the Commission's
regulations or PURA, and therefore we cannot hold it arbitrary and capricious.  See Gulf States Utils.
Co., 809 S.W.2d at 207.
	Furthermore, the Commission's decision to include the expenses is not inconsistent
with the statutory directive to set the fuel factor for the "electric utility as of December 31, 2001." 
The statutory regime provides for the Commission to determine the fuel factor, and is silent
regarding how fuel factors are set.  We are not persuaded by the argument that the use of the term
"electric utility" mandated a myopic snapshot limited to expenses borne by the bundled electric
utility on its last day of existence.  When the legislature enacted the rule, before unbundling, electric
utilities and not retail electric providers were the entities in existence.  When it directed the
Commission to set the fuel factor for the electric utility in PURA section 39.202(b), the legislature
intended for the retail electric provider charging the PTB to use that fuel factor beginning in 2002. 
See PURA § 39.202(a) (requiring retail electric providers to charge the PTB determined for utility). 
It would be illogical to hold that, when the statute required the fuel factor component of the PTB be
set "for" the electric utility, and the retail electric provider was the entity required to charge the PTB,
the legislature affirmatively intended not to set a fuel factor "for" the affiliated retail electric
provider. (14) See McLane Co. v. Strayhorn, 148 S.W.3d 644, 650 (Tex. App.--Austin 2004, pet.
denied) (we do not attribute to legislature intent to work foolish or absurd results).  We decline to
read an expression of legislative intent to specify a single detailed scheme of calculating the fuel
factor component of the PTB into the term "electric utility," particularly where that scheme conflicts
with that of the agency charged with determining the PTB.  See PURA § 39.202 (a)-(b) (authorizing
Commission to set PTB and determine base rates and fuel factor).  Similarly, the language, "as of
December 31, 2001" does not indicate to us a substantive edict as to how a fuel factor should be set;
it merely dictates when.  We believe that the legislature did not intend to override or change the
practice of taking into account cost estimates for the period in which a fuel factor will be in effect
when setting that fuel factor by specifying a date by which the Commission should set the fuel
factors for 2002.  The Commission's acts did not contravene the statutory language of PURA. 
	In short, these fuel factors were set in the traditional manner as outlined by the current
fuel rule: the Commission calculated them as of December 31, using reasonable estimates of
expenses during the period they would be in effect, the rate year 2002. (15)  Thus, Steering
Committee's, OPC's and Cities' arguments regarding the "continuing regulation" model do not
properly address whether the Commission erred.  We hold that the Commission was within its
authority to determine that the capacity-auction, UFE, QSE, TCM, and single area/multi-area
dispatch expenses were eligible fuel expenses to be used in setting the fuel factors.  We overrule
OPC's first issue in both WTU's case and CPL's case insofar as it addresses these expenses and
Steering Committee's and Cities' second issues.  

Reasonability and Substantial Evidence 
	Steering Committee and Cities appeal the district court's judgments affirming the
Commission's estimates of CPL's and WTU's coal and purchased power (16) estimates.  Steering
Committee adds its argument that the Commission erred in allowing CPL to include railcar-depreciation expenses; Steering Committee and Cities assert that the Commission's findings
concerning all three expenses were unreasonable and not supported by substantial evidence.  The
Commission, CPL, WTU, and New Power appeal the district court's ruling that the Commission's
finding 17A (accounting for a loss of 15% of generating capacity but still assuming 100% customer
load after deregulation) (17) was not supported by substantial evidence.  WTU appeals the district
court's ruling that there was insufficient evidence to support its UFE allowance.
 	We review Commission findings under the substantial evidence rule.  See PURA
§ 15.001 (West 1998) ("Any party to a proceeding before the commission is entitled to judicial
review under the substantial evidence rule.").  Under the substantial evidence rule, we may not inject
our own judgment but must defer to that of the Commission on the weight of the evidence on
questions committed to its discretion. (18)  Tex. Gov't Code Ann. § 2001.174 (West 2000).  We must
presume that the Commission's order is supported by substantial evidence; the complaining party
has the burden to overcome this presumption.  City of El Paso v. Public Util. Comm'n, 883 S.W.2d
179, 185 (Tex. 1994); Hammack v. Public Util. Comm'n, 131 S.W.3d 713, 725 (Tex. App.--Austin
2004, pet. denied).  "At its core, the substantial evidence rule is a reasonableness test or a rational
basis test"; if the order is reasonable, we do not concern ourselves with its correctness.  City of El
Paso, 883 S.W.2d at 185 (citing Railroad Comm'n of Texas v. Pend Oreille Oil & Gas Co., 817
S.W.2d 36, 41 (Tex. 1991)). 

Coal costs
	Steering Committee and Cities argue that, because CPL's and WTU's original coal
price estimates were based on an aberrant spike in coal prices and unreasonable estimates that coal
prices would remain high in 2002, the level the Commission used was unsupported by substantial
evidence.  They claimed that there was no evidence contradicting their assertion that the historical
price of coal was much lower.
	To support their coal estimates, CPL and WTU presented the testimony of Marguerite
Mills, who stated that both forecasts were based on actual, contractual coal prices and spot coal
forecasts.  She contended that Steering Committee's and Cities' coal estimates were unreasonably
low and explained, at length, the history and current trends of coal prices as well as her disagreement
with the Cities' witness regarding the feasibility of using cheaper coal.
	At best, Steering Committee and Cities have only shown that the evidence is
conflicting.  Because there is credible evidence to support the Commission's findings, Steering
Committee and Cities have failed to show that the Commission's decision was unreasonable.  City
of El Paso, 883 S.W.2d at 185.  We overrule Steering Committee's and Cities' fourth issues.

Purchased power costs
	Steering Committee and Cities argue that CPL's and WTU's purchased power
estimates, based on estimates of market prices on April 6, 2001, were too high because, by mid-July,
the price had dropped approximately $33 to $37 per megawatt hour due to a decrease in the price of
natural gas. 
	The Commission declined to update the purchased power costs in October when it
updated the natural gas cost under the PTB rule because the Commission's rules did not contemplate
an update for purchased power costs.  It also held that the methodologies employed by both CPL and
WTU provided legitimate estimates of 2002 purchased power costs.  In CPL's case, Stephan Haynes,
managing director of risk oversight for a subsidiary of CPL's and WTU's parent company, testified
to projected prices based on affiliated and independent companies' estimates, and the ALJ
recommended that the Commission retain the April price estimates.  Although Haynes gave the same
testimony in WTU's case, in that case, the ALJ sided with Cities' arguments that the July updates
were more accurate.  The Commission, in reviewing the ALJ's recommendations, decided to retain
the April estimates for both cases.  It was not persuaded that adjusting either estimate using more
recent July prices would result in a more accurate or reasonable estimate of purchased power for the
2002 rate year because purchased power prices always fluctuate and because the appellants had
failed to show a causal connection between the price of natural gas and the cost of purchased power. 
The purchased power contracts in WTU's and CPL's cases were based on existing contracts which
were not tied to the market price of natural gas.  Thus, the Commission had a reasonable basis for
determining that a change in the price of natural gas would not necessarily alter purchased power
costs estimates.  Because Steering Committee and Cities have not shown the finding to be
unreasonable or unsupported by substantial evidence, we overrule their third issues.

Railcar depreciation costs
	CPL included approximately $1.572 million in coal fuel expenses for depreciation
of aluminum rail cars.  Steering Committee argues that, without a depreciation rate study, the
evidence is insufficient to show that the rate the Commission included was reasonable.  OPC joins
in arguing that railcar depreciation expenses are more accurately categorized as a base rate expense
and cannot be included in the fuel factor.  The Commission noted that in some instances railcar
depreciation was treated as a base-rate expense and in others as a fuel-factor expense.  It also noted,
however, that the railcar depreciation expense had not been included in CPL's base rate and was an
actual, fuel-related expense, and heard evidence and argument that depreciation was a proper,
eligible fuel expense specifically listed in Federal Energy Regulatory Commission account 501.  See
16 Tex. Admin. Code § 25.236(a) (including in eligible fuel expenses those properly recorded in
FERC account 501, regarding depreciation on fuel transportation equipment).  We therefore affirm
the district court's holding that the Commission properly included this rate in the fuel factor and
overrule the remainder of OPC's first issue in both cases.
	Steering Committee also argues that the amount of expenses was unreasonable and
unsupported by evidence in the record.  We disagree.  CPL presented testimony from Randall
Hamlett, Manager of Registered Accounting Support for a subsidiary of WTU's and CPL's parent
company, and exhibits supporting the reasonableness of the expense, which was not disputed before
the Commission.  We conclude that there was substantial evidence to support the Commission's
ruling regarding the amount of the railcar depreciation expense and overrule Steering Committee's
seventh issue.

Capacity auction expense
	The trial court determined that the Commission's allowing CPL and WTU to account
for expenses incurred in replacing the loss of 15% of generating capacity while maintaining 100% 
customer loads was not supported by substantial evidence and that, in making that finding, the
Commission improperly shifted the burden of proof from the utility.  The Commission, WTU, CPL,
and New Power appeal these rulings.  
	They argue that their opponents failed to overcome the presumption that the
Commission's ruling was supported by substantial evidence because reasonable minds could have
concluded that the REPs would continue to serve 100% of their native load and because the utilities
were required by law to auction 15% of their generating capacity. (19)  The Commission points to the
testimony of witnesses Mark Gilbert (20) and Myron Adams (21) that the demand for electricity by the
native customer load was forecasted to be 100% at the beginning of competition and argues that
there was substantial evidence supporting the ruling.  We agree.  The Commission was free to accept
or reject the testimony of the witnesses, and even if the evidence had preponderated against its
decision, a reasonable basis exists in the record for the Commission's action.  See City of El Paso,
883 S.W.2d at 185.  Reasonable minds could have come to the Commission's conclusion. 
	The Commission stated that it would have supported a reasonable reduction in
forecasted sales if the record had reflected that such reduction existed or what amount of reduction
might occur.  The district court held, correctly, that it was WTU's and CPL's burden to prove the
costs for purposes of calculating the fuel factor.  See PURA § 39.003.  However, we disagree with
the district court that the Commission shifted this burden of proof.  Rather, when faced with TXU's
and CPL's evidence supporting a 100% customer load and a 15% capacity auction, and no evidence
to the contrary, the Commission found the utilities' position more tenable and ruled in their favor. 
See Central Power & Light Co. v. Public Util. Comm'n, 36 S.W.3d 547, 561 (Tex. App.--Austin
2000, pet. denied) (Commission had discretion to determine factual issues based upon evidence
before it).
	We hold that the Commission's decision was supported by substantial evidence and
that it did not shift the burden of proof and sustain the Commission's first and second issues in both
cases, New Power's first and second issue, and WTU's and CPL's first issues.

Unaccounted for energy (UFE) 
	Unaccounted for energy, the difference between metered generation and metered
customer load (consumption) on the ERCOT system, is determined by ERCOT on a system-wide
basis and allocated to REPs based on their share of total ERCOT sales. (22)  The Commission included
a uniform, system-wide 1% UFE expense allowance in determining WTU's fuel factor, although
WTU had not requested that it do so.  The district court reversed the Commission's findings
regarding WTU's UFE expenses for lack of substantial evidence because the Commission relied on
evidence outside the record to set UFE at 1%. (23)  WTU appeals, arguing that (1) although it did not
request UFE expenses in its initial case, there is nonetheless substantial evidence, in the form of
ERCOT protocols and procedures, and testimony by WTU witness Randall Hamlett, Manager of
Registered Accounting Support for a subsidiary of WTU's and CPL's parent company, regarding
UFE, and (2) WTU need not individually present evidence of UFE levels because the Commission
correctly applied its own precedent or ad hoc policy determinations in reaching its decision.
	Upon review, we find that there is not substantial evidence supporting the
Commission's decision to allow a 1% cost calculation for UFE in this case.  It is true that the
ERCOT protocols and Hamlett's testimony establish that UFE is an expense charged system-wide
on a prorated basis to all ERCOT users.  However, we find no evidence in this proceeding regarding
the proper amount of UFE allowance; no UFE estimate was offered.  Thus, the Commission's
inclusion of 1% and not some other amount was based upon decisions and evidence in other cases. 
We must therefore determine whether this qualifies as a correct application of Commission precedent
or ad hoc policy making.
	The Commission has determined that, "for policy reasons, it is appropriate to include
the same level of UFE in the PTB fuel factors of all affiliated REPs in ERCOT" because UFE is a
uniform cost.  WTU argues that, in adopting the uniform 1% UFE cost in this case, the Commission
was merely following its own precedent.  See Flores v. Employees Ret. Sys. of Tex., 74 S.W.3d 532,
544-45 (Tex. App.--Austin 2002, pet. denied) (agency should follow its own precedent or explain
departure from it).  However, given that no UFE assessment was ever raised or requested in this case,
and that the Commission cited to no prior rulings in support of its 1% determination, we are not
persuaded that the Commission intended to apply its reasoning or ruling from former cases
containing evidence supporting UFE estimates.  We are unconvinced that the Commission included
the 1% in order to follow established precedent.
	WTU next argues that the Commission's policy of including a uniform 1% UFE
estimate in every ERCOT REP's case was effectuated by ad hoc rulemaking in a prior proceeding. 
In some circumstances, the Commission implements its policy choices through ad hoc rulemaking,
statements interpreting, implementing, or prescribing agency law or policy.  Texas Ass'n of Long
Distance Tel. Cos. v. Public Util. Comm'n, 798 S.W.2d 875, 886 (Tex. App.--Austin 1990, writ
denied) ("TEXALTEL"); City of El Paso, 883 S.W.2d at 188-89 (ad hoc adjudication preferred
where agency does not have sufficient experience to warrant rigid rule or where problem is too
specialized for general rule treatment).  Because the uniform percentage was a legislative fact or
policy established in a prior proceeding, WTU contends, there is no need for record evidence in this
case because ad hoc rules implementing policy need not be supported by a record containing direct
evidence regarding their accuracy.  See TEXALTEL, 798 S.W.2d at 887 (permitting Commission to
set ceiling at 145% increase in rates to prevent "severe customer impact" without evidence that
145% of current rates would not cause said impact).  The nature of the decision in question belies
this claim; the Commission nowhere indicated that it had set a rule in another case governing the
disposition in WTU's case, nor did it cite to a previous proceeding for authority supporting its
decision.  Rather, Commission findings of fact 43B and 43C, although they mention policy while
asserting that 1% is the appropriate and a reasonable level for UFE, do not refer to an ad hoc rule
from any other particular case.
	Instead, they appear to apply evidence from other dockets, arguing that "[1%]
represents a lower end of the presented range in the various PTB cases" without citing any support
from WTU's case.  WTU now argues that the Commission may apply relevant evidence from the
other cases to this proceeding, citing West Tex. Utils. Co. v. Office of Pub. Util. Counsel, 896 S.W.2d
261 (Tex. App.--Austin 1995, no writ) ("West Tex. Utils."), in which, it argues, the Commission
applied depreciation rates established in a prior proceeding, rejecting a proposal to change those
rates.  Id. at 267.  In West Tex. Utils., the Commission's final order set certain depreciation rates and
left others, set by a prior proceeding involving the same utility unchanged; it did not apply evidence
from another case to support a finding in the case before it.  Id. at 269 ("all parties . . . were bound
by the Commission's prior decision . . . absent a showing of changed conditions that would
necessitate an adjustment"), 270 ("In the present case, the Commission did not rely on findings of
fact from a previous case to support a new order concerning depreciation rates.  The Commission
merely declined to adjust depreciation rates established in a prior final order.").  West Tex. Utils. is
wholly inapplicable here, where WTU urges that the Commission may use facts found in earlier
proceedings involving different parties to support findings in later proceedings. (24) 
	Because there is not substantial evidence supporting this inclusion in this case and
because the Commission was not engaged in ad hoc rulemaking, but merely applied evidence from
other dockets and cases, we overrule WTU's second issue.
	Steering Committee also raises a UFE issue on appeal: it argues that the district court
erred in affirming the Commission's grant of UFE costs to CPL because there was not substantial
evidence supporting that decision in CPL's case.  The record reveals that witness John Gillespie
testified before SOAH in CPL's case, recommending a positive UFE level be set for CPL and
estimating that it fall between 2.2% and 4%, and explaining the basis of his estimates by illustrating
similarities between the California and Texas markets and the effects of competition.  The
Commission used all this information to decide to include a UFE level of 1%.  This evidence on
projected UFE was not lifted by the Commission on its own motion from another case, and the fact
that the Gillespie's expert opinion was based on the experiences of other utilities has no effect on
its validity, absent a showing that the comparisons were unhelpful.  Thus, there was substantial
evidence supporting the Commission's ruling.  We overrule Steering Committee's fifth issue. 

Procedural challenges

	OPC, Steering Committee, and Cities accuse the Commission of violating their due
process rights to a fair and impartial hearing.  In one issue with three subparts, Steering Committee
and Cities each argue that Commission Chairman Mario Yzaguirre and Commissioner Brett Perlman
should have recused themselves from consideration of both CPL's and WTU's applications because
both maintained ties with Enron, parent company of intervenor New Power, during the application
and review process.  Second, Steering Committee, Cities and OPC contend that the Commission
denied them an opportunity to present evidence concerning CPL's and WTU's natural-gas-price
updates and that the Commission treated them differently than other similarly situated ratepayers.
Third, Steering Committee and Cities contend that they were denied due process when the
Commission discussed "headroom" issues with witnesses not associated with either CPL's or
WTU's proceeding.
	The appellants bore the burden of proof at trial to establish the procedural
irregularities they allege.  Hammack, 131 S.W.3d at 729.  Here they bear the burden of
demonstrating that the trial court's failure to find the alleged irregularities was against the great
weight and preponderance of the evidence.  Id.

Recusal
	Cities and Steering Committee accuse Yzaguirre and Perlman of having a conflict of
interest based on their ties to Enron. (25)  Steering Committee and Cities argue that Yzaguirre's and
Perlman's continued ties to Enron and Yzaguirre's failure to fully disclose his employment history
with Enron created an impermissible conflict of interest. (26) See Lewis v. Guaranty Fed. Sav. & Loan
Ass'n, 483 S.W.2d 837, 843 (Tex. App.--Austin 1972, writ ref'd n.r.e.) (commissioners should
avoid "any conduct tending to undermine faith and confidence in the man or the office in which he
acts"). (27)
 	PURA disqualifies directors, employees, controllers, owners, investors, or interested
parties of utility companies from holding a commission unless they notify the attorney general and
divest themselves of the interest. PURA § 12.152 (West Supp. 2004-05).  Commissioners must be
recused if their impartiality is "reasonably questioned."  See 16 Tex. Admin. Code § 22.3(d) 2005). (28) 
The Commission's recusal rule is similar to Texas Rule of Civil Procedure 18b, which states that
"a judge shall recuse himself in any proceeding in which: (a) his impartiality might reasonably be
questioned."  Under rule 18b, "[r]ecusal is appropriate if the movant has provided enough facts to
establish that a reasonable person, knowing all the circumstances involved, would harbor doubts as
to the impartiality of the trial court, but only when the bias is of such a nature and extent as to deny
the movant due process of law."  Rosas v. State, 76 S.W.3d 771, 774 (Tex. App.--Houston [1st
Dist.] 2002, no pet.) (citing Kemp v. State, 846 S.W.2d 289, 306 (Tex. Crim. App.1992)).
	Due process at a minimum requires notice and an opportunity to be heard at a
meaningful time and in a meaningful manner.  Mathews v. Eldridge, 424 U.S. 319, 333 (1976).  In
administrative proceedings, due process requires that parties be accorded a full and fair hearing on
disputed fact issues.  City of Corpus Christi, 51 S.W.3d at 262; see also Tex. Gov't Code Ann.
§§ 2001.051-.121 (West 2000); 16 Tex. Admin. Code §§ 22.202-.228 (2005).  We presume that
decision makers are fair and unbiased.  Hammack, 131 S.W.3d at 731.  A decisionmaker exhibits
impermissible bias when "[t]he bias . . . come[s] from an extrajudicial source and result[s] in an
opinion on the merits of the case other than what the judge learned from participating in the case." 
Rosas, 76 S.W.3d at 774.
	Neither Steering Committee nor Cities has shown the presence of a conflict of interest
or bias.  Steering Committee and Cities fail to produce the extrajudicial facts they claim played a role
in the Commission's final decision.  They fail to allege that Yzaguirre or Perlman had any personal
or private interest in either CPL's or WTU's applications.  Although they accuse Yzaguirre and
Perlman of maintaining social contacts with Enron affiliate New Power, they do not explain how that
relationship prejudiced the Commission in favor of CPL or WTU. (29)  That the Commissioners had
contact with the utilities they regulate is unremarkable absent a showing by appellants that the
contacts were of such a nature that they would reasonably call the Commissioners' impartiality into
question.  See Rosas, 76 S.W.3d at 774 (citing Kemp, 846 S.W.2d at 305) (applying identical
language from Tex. R. Civ. P. 18(b), holding recusal only appropriate if movant has provided facts
to establish that reasonable person, knowing the circumstances, would doubt impartiality, but only
when nature and extent of bias is such as to deny movant due process of law); see also Charles H.
Koch, Jr., Administrative Law and Practice § 6.10 (2d ed. 1987) (past business association would
not support allegation of conflict of interest and mere allegation will not overcome presumption of
honesty and integrity in administrative adjudicators).
	We hold that Steering Committee's and Cities' allegations that the Commissioners
met with and maintained social contacts with people affiliated with Enron are insufficient to raise
a reasonable question as to their impartiality.  Thus, we overrule Steering Committee's and Cities'
first issues.  

The natural-gas-price update
	OPC, Steering Committee, and Cities argue that the Commission erred by not
allowing them to present evidence at CPL's and WTU's natural-gas-price true-up proceeding on
October 1, 2001, when other, similarly situated, ratepayers were allowed to introduce evidence at
other proceedings. (30)  Because the price of natural gas could affect purchased power costs as well, in
October Steering Committee and Cities reasserted their arguments that CPL's and WTU's purchased
power estimates were too high because they failed to reflect the decline in the price of natural gas. 
CPL and WTU argued that the price of purchased power was not relevant in a proceeding updating
natural gas prices.
	Pursuant to an agreement of the parties, the ALJ in each proceeding referred the
natural gas price update to the Commission for consideration. (31)  Although neither ALJ made formal
recommendations, each opined that the October natural gas price update was intended to reconcile
CPL's and WTU's natural-gas allowances, not to adjust for purchased power costs.  They also
commented that Steering Committee and the Cities had failed to prove a relationship between the
price of natural gas and the price of purchased power. (32)
	OPC, Steering Committee, and Cities requested a hearing on the natural gas price
update in both proceedings and filed affidavits claiming that both CPL's and WTU's purchased-power expense estimates were inflated because they did not reflect the substantial decrease in the
price of natural gas that occurred in mid July, and that they had not had an opportunity to fully
litigate the natural gas price issues because information relevant to the update had not been available
prior to October.  It was "understood at the beginning of the fuel factor case," OPC contended, that
the October update filings and proceedings would be separate from the June and July fuel factor
application filings and determinations.  The Commission staff filed motions to strike the affidavits,
arguing that OPC,  Steering Committee, and Cities were attempting to relitigate the purchased-power
issue and that there was no direct correlation between the prices of natural gas and purchased power. 
	At the November 7, 2001 hearing on the natural gas price updates, the Commission
excluded Steering Committee, Cities, and OPC affidavits attempting to link the prices of natural gas
and purchased power.  Nevertheless, in its final orders, the Commission concluded that it was proper
to adjust an electric utility's purchased-power costs at a true-up proceeding to the extent those costs
could be directly indexed to the price of natural gas and adjusted CPL's fuel factor accordingly. (33)
	OPC argues here that the Commission abused its discretion in excluding the evidence
on the relationship between the prices of natural gas and purchased power because the scope of the
inquiry in the true-up proceeding required the Commission to examine all market factors that could
impact the price of natural gas, not just the market price of natural gas.  It also argues that the
exclusion of its evidence shifted the burden of proof from the utilities to the parties in opposition. 
OPC, Steering Committee and Cities all claim that the Commission impermissibly treated them
differently than other ratepayers.  See PURA § 36.003(b) (West 1998) (prohibiting "unreasonably
preferential, prejudicial, or discriminatory" rates). 
Purchased power
	OPC argues that, in excluding its evidence and denying a hearing, the Commission
abused its discretion and denied ratepayers due process.
	In administrative proceedings, due process requires that parties be accorded a full and
fair hearing on disputed fact issues.  City of Corpus Christi, 51 S.W.3d at 262; Hammack, 131 S.W.3d
at 731; see also Tex. Gov't Code Ann. §§ 2001.051-.121; 16 Tex. Admin. Code §§ 22.202-.228.  At
a minimum, it requires that the "rudiments of fair play" be observed.  Hammack, 131 S.W.3d at 731
(quoting State v. Crank, 666 S.W.2d 91, 94 (Tex. 1984)).  This is not to say that administrative
hearings must measure up to judicial standards, but even they cannot be arbitrary or inherently unfair. 
City of Corpus Christi, 51 S.W.3d at 262 (citing Bexar County Sheriff's Civil Serv. Comm'n v. Davis,
802 S.W.2d 659, 664 (Tex.1990)).  Procedural irregularities do not warrant reversal absent a showing
of harm.  City of Corpus Christi, 51 S.W.3d at 262, 264 (Commission's "failure to follow procedural
requirements of statutes or rules is not reversible error without a showing of harm").  In order to show
harm and obtain a reversal on the grounds that the Commission wrongly excluded evidence requires
a showing that the evidence is controlling on a material issue, not merely cumulative.  See Railroad
Comm'n of Tex. v. Rio Grande Valley Gas Co., 683 S.W.2d 783, 789 (Tex. App.--Austin 1984, no
writ) (citing Lewis v. Metropolitan Sav. & Loan Ass'n, 550 S.W.2d 11, 14 (Tex. 1977)). 
	After reviewing the record and OPC's arguments, we conclude that the OPC has failed
to show that it was harmed by the denial of a hearing or exclusion of evidence.  It is undisputed that
the Commission considered the relationship between the market price of natural gas and its effect,
if any, on purchased power costs and agreed with OPC's position that the price of natural gas could
affect the price of purchased power.  The Commission, however, did not agree that the market price
of natural gas had a direct effect on CPL's and WTU's contract prices for natural gas.  It found, with
one exception, that the market price for natural gas would not directly affect CPL's and WTU's
natural gas prices because those prices were set by contract and not specifically indexed to the market
price of natural gas.  Thus, the prices others paid for natural gas were not controlling on the issue of
CPL's and WTU's actual contractual gas prices. 
	While OPC argues that its October update testimony was relevant to the proper
updated price of natural gas in that it would show that CPL and WTU had failed to lower their
purchased-power costs in light of the changes in the price of natural gas, we note that Steering
Committee and Cities presented evidence that CPL's and WTU's natural gas cost projections were
too high because they failed to account for decreases in the price of natural gas.  OPC has failed to
specify what, if anything, the offered testimony would have added that was materially different from
the admitted evidence.  Because OPC has not shown that the evidence was material and not
cumulative, we hold that it was not reasonably calculated to cause the rendition of an improper order.
Rio Grande Valley Gas Co., 683 S.W.2d at 789.  Absent this showing of harm, any procedural
irregularities do not warrant reversal.  City of Corpus Christi, 51 S.W.3d at 264.
	OPC also argues that the exclusion of evidence shifted the burden from the utilities
to the parties in opposition.  While there is no doubt that the burden of proof lies with the utilities,
see PURA section 39.003 (West Supp. 2004), the exclusion of evidence did not change the burden
of proof to the objecting parties.  Both CPL and WTU were required to and did present evidence
substantiating their purchased-power expenses.  That OPC was prohibited from presenting certain
evidence to the contrary does not constitute burden shifting.  We hold that OPC was not harmed by
the exclusion of its evidence.
Disparate treatment
	Steering Committee, Cities, and OPC assert that they were treated differently than
other similarly situated ratepayers in that the Commission made the purchased-power adjustments
based on the market price of natural gas in three other proceedings, TXU's, TNMU's, and Reliant's. 
See PURA § 36.003(b) (prohibiting unreasonably preferential, prejudicial, or discriminatory rates
across classes of consumers).  We conclude that they have failed to show that they were treated
differently than similarly situated ratepayers.  First, because Reliant's case and TNMP's case were
settled, there could be no comparison between the Commission's actions in those cases and its actions
here; the ratepayers in those cases were not "similarly situated," for purposes of applying precedent. 
See Southwestern Bell Tel. Co. v. Public Util. Comm'n, 31 S.W.3d 631, 641 (Tex. App.--Austin
2000) (no precedential value to settled cases), aff'd, 92 S.W.3d 434 (Tex. 2002).  Second, the
Commission's methodology was consistent.  The Commission made an adjustment in CPL's case but
not in WTU's case because one of CPL's natural gas contracts was "specifically indexed" to the price
of natural gas.  The Commission similarly permitted an adjustment in TXU's case because it had
contract pricing specifically indexed to the price of natural gas.  

Headroom
	Steering Committee and Cities contend that the Commission erred by requesting and
receiving evidence outside the record on headroom issues without opportunity for cross examination. 
"Headroom" refers to the margin between the PTB and the new REPs' costs of providing electricity. 
See Reliant Energy v. Pub. Util. Comm'n of Tex., 62 S.W.3d 833, 837 n.5 (Tex. App.--Austin 2001,
no pet.).  This profit margin has a powerful effect on competition; if the PTB includes a great deal
of headroom, new market entrants will find it easier to undercut affiliated retail electric providers'
prices and still make a profit than if the PTB is closer to the cost of providing electricity.
	Steering Committee and Cities argue that an inordinate concern regarding headroom
shows that the Commissioners were biased in favor of the utilities.  They point to the testimony of
Brian Lloyd, a Commission staff member, and Charles Griffey, a witness for Reliant in its previous
docket, who participated in an October 18, 2001, open meeting set to discuss CPL's, WTU's, and
other utilities' applications to implement their fuel factors.  Lloyd and Griffey appeared before the
Commission and discussed the creation of a spreadsheet that could be used to examine and compare
the different PTB rates established by the Commission, as was done in Reliant's case.  In a follow-up
memo to the Commission, Lloyd stated that he had created two spreadsheets, which were
programmed to show how a change in one particular input, for example, the price of natural gas,
would reflect a corresponding effect on the PTB rate.
	They also point to Perlman's comments at the December 3, 2001 open meeting in
which he said, "I've been deeply disappointed that we're not here having a substantive hearing on
whether there is sufficient headroom in the market for new entrants to compete in the marketplace." 
Commissioner Klein suggested that the Commission solicit feedback from nonaffiliated REPs to see
whether they planned to compete:

If it turns out that at the end of the day . . . of the 30 or so some odd REPs or
whatever the number is in Texas, if some proportion of them say "yes, we will
compete in Houston, Dallas and Corpus Christi," then I think we have an answer
from the marketplace as a whole and we've received the feedback we need.


Yzaguirre clarified that what the Commission would be asking was not additional cost data but a
survey of the REPs to see if they were, in fact, planning to compete against the affiliated REPs. 
Commission Perlman agreed, "all I'm looking for is a one-page affidavit that says 'I like the rules. 
I'm going to compete for small residential--for residential customers.'" 
	Steering Committee and Cities argue that the Commission improperly considered
evidence not in the record from the REPs and solicited Lloyd's and Griffey's input on the
spreadsheet without providing an opportunity to cross examine either witness. 
	We believe that Steering Committee and Cities mischaracterize the role the Lloyd
follow-up memo played.  Commission staff member Lloyd simply created a spreadsheet, possibly
based in part on a model provided by Griffey, which allowed the Commissioners the chance to view
the different PTB rates and to track effects changes in any given input might have on the PTB rate. 
Because the memo concerned only the spreadsheet, and Lloyd was a nonparticipating staff member
properly working to evaluate evidence, the Commission did not solicit or receive facts not made part
of the record or violate the prohibition against ex parte communications.  See Tex. Gov't Code Ann.
§ 2001.061(c) (West 1998) (ex parte communications with Commission employees who have not
participated in hearing in case at issue are permitted so agency may use its specialized skill or
knowledge in evaluating evidence); Hammack, 131 S.W.3d at 732.  Although Lloyd did ultimately
file testimony and participate in a hearing, we believe that this does not render his memo work
suspect, as his testimony was not filed until November.  Thus, at the time the Commission
communicated with him as its staff member, he had not participated in a hearing.
	Second, Steering Committee and Cities do not attempt to show how the
Commission's judgment in either CPL's or WTU's case was affected by any ex parte
communications.  See id. at 731-32.  They must overcome the presumption that the Commissioners
were fair, honest, and unbiased.  Id. at 731.  They simply make the tenuous assertion that the
Commission was concerned about headroom and was therefore biased.  While it does appear that
the Commission was concerned that there be enough headroom, it does not necessarily follow that
such a concern demonstrates bias, or that an increase in headroom would be in the utilities' long-term interests.  The Commission is charged with balancing PURA's competing policy
considerations, including electric consumers' interest in lowering costs and new market entrants'
interest in establishing competition.  See Reliant Energy, 62 S.W.3d at 838.  That the Commission
struck that balance other than where Steering Committee and Cities would have preferred is no
indication of bias.  A higher PTB which included headroom would increase utility profits in the short
term but ultimately encourage competition with the utilities, which the Commission is authorized
to do.  Indeed, we have suggested that, because of its authority to set the initial PTB, the
"Commission could ensure initial adequate headroom" if it so chose.  Reliant Energy, 62 S.W.3d at
838.
	We hold that the spreadsheet and memo did not constitute impermissible extra-record
evidence and that the Commission was within its authority to address concerns regarding the PTB's
effects on competition.  
	Because there was no harmful exclusion of evidence and because the ratepayers were
not treated differently from similarly situated persons, and because the appellants failed to overcome
the presumption of impartiality or show harm resulting from any procedural error we overrule OPC's
second issue in WTU's and CPL's case and Cities' and Steering Committee's first and fifth issues
and Steering Committee's sixth issue.
CONCLUSION

	We hold that the Commission properly included the challenged expenses in
determining the fuel factors for CPL and WTU; that the Commission's estimates of the amounts of
the challenged costs, with the exception of its ruling allowing WTU's UFE allocation, were
supported by substantial evidence; and that OPC, Steering Committee, and Cities failed to show any
harmful procedural error.  We overrule all of OPC's, Steering Committee's, and Cities' issues and
WTU's second issue.  WTU's first issue, the Commission's and New Power's first and second
issues, and CPL's first issue are sustained.
	We reverse that part of the judgments of the district court concluding that finding 17A
in each case was not supported by substantial evidence and that the Commission improperly shifted
the burden of proof.  We render judgment reinstating finding 17A in each case.  We affirm the
district court's judgments in all other respects.  Accordingly, pursuant to the district court's
judgment, WTU's case is remanded to the Commission for further proceedings relating to findings
43A, 43B, and 43C concerning the inclusion of UFE costs, based upon the existing administrative
record, see Reliant Energy, Inc. v. Public. Util. Comm'n, 153 S.W.3d 174, 192 (Tex. App.--Austin
2004, no pet.).

  
					David Puryear, Justice
Before Chief Justice Law, Justices Patterson and Puryear
Affirmed in Part; Reversed and Rendered in Part
Filed:   July 28, 2005
1.   CPL and WTU are owned by the same parent company, AEP, Inc.
2.   In City of El Paso v. El Paso Elec. Co., we explained that an electric utility is entitled to
recover through its rates sums expended for reasonable and necessary operating expenses, including
the cost of fuel-related items.  851 S.W.2d 896, 898 (Tex. App.--Austin 1993, writ denied).  We
also noted that an electric utility incurs fuel costs directly when it generates its own electric power
and indirectly, as an element of the price paid, when the utility buys electric power from another. 
Id.
3.   Eligible fuel expenses are "defined in § 25.236(a) [sic] of this title (relating to Recovery
of Fuel Costs)."  16 Tex. Admin. Code § 25.237 (2005).  Eligible fuel expenses include expenses
recorded in the Federal Energy Regulatory Commission ("FERC") Uniform System of Accounts,
numbers 501, 503, 518, 536, 547, 555, and 565, with certain limitations, but in special
circumstances, an electric utility may recover as eligible expenses fuel or related expenses otherwise
excluded by the limitations where the commission considers whether those expenses are related to
increased reliability, lower costs or other benefits to ratepayers.  Id. § 25.236(a).  Here, the parties
do not argue whether these expenses are properly included in the FERC accounts, but whether the
Commission's comments in setting the PTB rule and PURA's mandate that each utility's fuel factor
be set as of December 31, 2001, categorically exclude these otherwise eligible expenses.  See id.
§ 25.237; PURA § 39.202(b).  Thus, we will not determine whether the excluded expenses are
properly included in the FERC accounts.
4. 	OPC is a state agency representing the interests of residential and small commercial
consumers.  PURA § 13.001 (West 1998).
5. 	PURA section 39.153 requires an electric utility to sell 15 percent of its electric capacity
at auction sixty days prior to deregulation.  CPL and WTU argued that, because utilities could not
provide electricity to 100 percent of their customer bases with their remaining 85 percent capacity,
they would necessarily incur costs of purchasing replacement power.
6. 	UFE is the difference between metered generation (supply) and metered consumption
(delivery).  When an electric utility has generated more electricity than has been accounted for in
delivery, the costs of generation are not fully covered by incoming revenues.  CPL and WTU
attempted to include the wasted electricity as a fuel expense.  
7. 	QSE and TCM expenses are part of a utility's congestion management fee, a new cost
associated with "the transition to single control area operations in ERCOT"; ERCOT, the Electric
Reliability Counsel of Texas, is the interconnected network for transmitting power over a single grid
across the state.  See PURA § 31.002(5) (West Supp. 2004).  
8. 	As a result of deregulation, it was necessary for CPL and WTU to terminate contracts with
other electric utilities to jointly dispatch electricity, thereby improving operating efficiency by
reducing the number of hours during which inefficient gas-fired units are operated.  They argued that
the lost efficiencies from these single area/multi-area dispatch arrangements were eligible expenses
to be considered in their fuel factor calculations.
9. 	See Application of Central Power and Light Company, Docket No. 24195 (Order on
Rehearing, Feb. 7, 2002); Tex. Pub. Util. Comm'n, Application of West Texas Utility Company,
Docket No. 24335 (Order, Dec. 21, 2001).
10. 	The Commission adjusted one of CPL's natural-gas contracts, which was indexed to the
market price of natural gas.
11. 	OPC and Cities separately filed suit against the Commission regarding CPL's application. 
Their suits were consolidated into one case, GN2-0289.  Steering Committee and OPC also filed suit
against the Commission regarding WTU's application, and their causes were also consolidated into
one case, GV2-00906.  Both consolidated cases were tried together. 
12.   In fact, WTU and CPL argue in their post-submission letter that the costs at issue were
neither REP costs nor costs occurring as a result of deregulation, and that some of them began to
occur even before utilities unbundled.  
13.   The Commission has the authority to incorporate known and measurable changes to test
year data at its discretion.  See Central Power & Light Co. v. Public Util. Comm'n, 36 S.W.3d 547,
563 (Tex. App.--Austin 2000, pet. denied) (citing City of El Paso v. Public Util. Comm'n, 883
S.W.2d 179, 188 (Tex. 1994)).  
14. 	REPs do not bear fuel costs except as reflected in their costs in obtaining power. 
However, the fuel factor still determines the PTB that REPs are required to charge certain customers. 
Hence, while recognizing that the REP does not directly incur any costs included in the fuel factor,
we realize that the fuel factor used to determine the REP's PTB is in some sense set "for" the REP.
15. 	We agree with the Commission that the contest between the "continuing regulation" model 
and the "deregulated market model" is largely illusory; the real question is whether allowing these
particular expenses, which coincide with deregulation, fits within the fuel rule's guidelines for
calculating a fuel factor.  
16.   Purchased power costs are those costs associated with the purchase, by contract or on the
open market, of additional power.  See 16 Tex. Admin. Code § 25.5(1), (50), (94) (2005).
17.   Finding 17A was identical in each of the proceedings at the Commission.  
18.   PURA gives the Commission the authority to regulate and supervise utilities, to fix and
regulate their rates, and to ensure that rates and services are just and reasonable.  Public Util.
Comm'n v. GTE-Southwest, Inc., 901 S.W.2d 401, 407 (Tex. 1995).  
19.   "Each electric utility . . . shall sell at auction, at least 60 days before the date set for
customer choice to begin, entitlements to at least 15 percent of the electric utility's Texas
jurisdictional installed generation capacity.  For the purposes of this section, the term 'electric utility'
includes any affiliated power generation company that is unbundled from the electric utility . . . ." 
PURA § 39.153(a).
20.   Mark Gilbert is Manager of Economic Forecasting for a subsidiary of AEP, the parent
company of WTU and CPL.  
21.   Myron Adams is employed as Director of Integrated Resource Planning by AEP.
22.   WTU and CPL point out that ERCOT costs, which applied to electric utilities before
competition began, are relevant to the question of the cost of producing power in 2002.  
23. 	The district court reversed the Commission's findings 43A, 43B, and 43C.  They read as
follows:

43A.	Because UFE costs are actual costs that, under the new ERCOT
protocols, will be allocated to all REPs, it is reasonable to include UFE costs
in WTU's calculation of eligible fuel expenses.

43B.	The appropriate level for UFE costs across ERCOT is 1% of kilowatt-hour (kWh) sales, which represents a lower end of the presented range in the
various PTB cases.  For policy reasons, it is appropriate to include the same
level of UFE in the PTB fuel factors of all affiliated REPs within ERCOT.

43C.	It is reasonable for WTU to include UFE costs in the amount of one
percent of its kWh sales in its eligible fuel expense.

Because the district court appears to have affirmed the Commission's determination that UFE costs
are an eligible expense by allowing UFE expenses in CPL's case, we read its rejection of finding
43A as a holding that inclusion of UFE costs in WTU's case was not reasonable because it was not
based upon substantial evidence.  We address this point in this section.  To the extent that the district
court's reversal of 43A could be read as a determination that UFE is not an eligible expense, we
would reverse that determination based upon the eligibility discussion above.
24. 	We note that an agency may take official notice of generally recognized facts within its
area of specialized knowledge, even if they are not judicially cognizable.  Tex. Gov't Code Ann.
§ 2001.090 (a) (West 2000).  In this case, though, there is no indication that the Commission took
official notice.  Also, 
 
[a]n agency's power to take official notice of a matter within its specialized
knowledge is always subject to the proviso that the parties must be given
adequate advance notice of the facts which the agency proposes to notice, and
given adequate opportunity to show the inaccuracy of the facts or the fallacy of
the conclusions which the agency proposes tentatively to accept without proof. 
To satisfy this requirement, it is necessary that a statement of the matters
noticed be incorporated into the record.  The source material upon which the
agency relies should, on request, be made available to the parties for their
examination.

Railroad Comm'n of Tex. v. Lone Star Gas Co., 611 S.W.2d 911, 913-14 (Tex. App.--Austin 1981,
writ ref'd n.r.e.) (applying predecessor to government code section 2001.090).  No such notice was
provided here.
25.   Cities argue that the Commissioners' previous business relationships with Enron,
continuous statements and focus on headroom or REP profit, request and receipt of evidence outside
the record concerning headroom, "several outlandish decisions contrary to the interest of ratepayers
and financially beneficial to New Power," and Yzaguirre's resignation from the Commission under
pressure due to his previous relationship with Enron undermined confidence that the Commission
performed its duties in a fair, unbiased manner.
26. 	According to Cities and Steering Committee, Yzaguirre failed to publicly disclose his
employment history with Enron pursuant to government code section 572.058.  See Tex. Gov't Code
Ann. § 572.058 (West 1994) (requiring Commissioners to publically disclose "a personal or private
interest in a measure, proposal, or decision pending before" the Commission).  Although Yzaguirre
revealed his previous employment by Enron de Mexico, they contend that he should have also
disclosed his employment history with Enron North America Corp. during the application process.
27. 	For example, in Lewis, we held that it was a denial of due process for the Savings and
Loan Commissioner conducting an ex parte investigation to consider evidentiary matters outside the
administrative record, likening his duty to that of a judge "charged with the solemn trust to act fairly
and impartially in fulfilling invested duties."  Lewis v. Guaranty Fed. Sav. & Loan Ass'n, 483
S.W.2d 837, 843 (Tex. App.--Austin 1972, writ ref'd n.r.e.). 
28. 	A commissioner shall recuse himself if the "commissioner in fact lacks impartiality or the
commissioner's impartiality has been reasonably questioned," or if he or a relative has an interest
in or has participated in the matter in question. 16 Tex. Admin. Code § 22.3(d).
29.   Steering Committee and Cities claim that Yzaguirre and Perlman had "business and social
contact with Enron and New Power officials and representatives," citing, for instance, Yzaguirre's
meeting with New Power and Enron representatives and Perlman's meeting with such
representatives "several times" during the pendency of the cases, discussing such matters as ERCOT
issues, deregulation, and market and competition issues.  Perlman was invited to a New Power
cocktail reception, to dine with New Power's Manager of Government Affairs, and dined with New 
Power's Chief Operational Officer during 2001.  New Power also apparently provided information
on its financial results and exchanged emails and letters.  
30.   A "true-up" proceeding reconciles estimated costs with actual costs.  See State v. Public
Util. Comm'n of Tex., 131 S.W.3d 314, 326 (Tex. App.--Austin 2004, pet. denied).  This natural-gas-price true-up was to reconcile CPL's and WTU's previous estimates with more recent data: the
average price of natural gas over a ten-day period ending September 15, 2001.  See Tex. Admin.
Code § 25.41(f)(3)(D)(I) (2005).
31. 	Both natural-gas price proceedings were consolidated in a contested-case hearing
unconnected with other proceedings and designated docket number 24460. 
32. 	The ALJ in WTU's case said:

[T]he PTB rule does not accommodate an October update to power costs. . . .
The PTB rule singles out natural gas costs for an October update, but
specifically provides that all other inputs into the calculation of the fuel factors
will be based on the record developed in this proceeding. . . .  The ALJ is
unsatisfied that Cities have established a consistent connection between natural
gas prices and purchased power.

	The ALJ in CPL's case noted that CPL presented "convincing evidence that while power
prices can move with gas prices, there is not a consistent relationship between them." 
33.   In findings of fact 51A and 51B in CPL's order, the Commission approved a purchased-power adjustment because CPL had one purchased-power contract that was specifically indexed to
the price of natural gas.  In findings of fact 24C and 24D in WTU's order, the Commission noted that
no adjustment was warranted because none of WTU's contracts were indexed to the price of natural
gas.
