TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN

NO. 03-03-00463-CV

Cities of Abilene, San Angelo, and Vernon, Appellants v.

Public Utility Commission of Texas and AEP Texas North Company, Appellees

FROM THE DISTRICT COURT OF TRAVIS COUNTY, 261ST JUDICIAL DISTRICT NO. GV201061, HONORABLE LORA J. LIVINGSTON, JUDGE PRESIDING

OPINION

Appellants Cities of Abilene, San Angelo, and Vernon (“the cities”) appeal a district court judgment that affirmed a final order of the Public Utility Commission (“Commission”) in favor of AEP Texas North Company (“AEP”).1 The Commission determined that a prior settlement order was ambiguous with respect to the recovery of certain costs incurred before the commencement of commercial operations at the Southwest Mesa Wind Farm and that these costs could be recovered in a fuel reconciliation proceeding. See Tex. Util. Code Ann. § 36.203 (West 1998). Additionally, the Commission determined that costs associated with AEP’s Oklaunion plant were recoverable in

the fuel reconciliation proceeding. The cities assert that (1) the prior settlement order foreclosed AEP’s ability to recover costs incurred before the commencement of commercial operations at the Southwest Mesa Wind Farm; and (2) the Commission erred in determining that costs associated with AEP’s Oklaunion plant were recoverable because the Commission applied the incorrect standard to determine the Oklaunion plant’s efficiency. We will affirm the judgment of the district court.

BACKGROUND AND PROCEDURE

The Public Utility Regulatory Act allows utilities to recover fuel costs separately from non-fuel, or base costs. See Tex. Util. Code Ann. § 36.203 (West 1998); see also Public Utility Regulatory Act, id. §§ 11.001-64.158 (West 1998 & Supp. 2004) (“PURA”). In a fuel reconciliation proceeding, the utility has the burden to demonstrate that “its eligible fuel expenses during the reconciliation period were reasonable and necessary expenses incurred to provide reliable electric service to retail customers.” 16 Tex. Admin. Code § 25.236(d)(1)(A) (2004).

On December 28, 2000, AEP filed an application for authority to reconcile fuel costs and purchased power costs from July 1, 1997, through July 30, 2000. As part of this request, AEP sought reconciliation of its purchased power costs incurred before the commencement of commercial operations of the Southwest Mesa Wind Farm under its contract with West Texas Wind Energy Partners (“Wind Partners contract”). Additionally, AEP sought to recover costs associated with its Oklaunion coal-fired power plant (“Oklaunion costs”).

The cities contested whether these costs were recoverable in the fuel reconciliation proceeding. The Commission had previously approved a settlement concerning the Wind Partners contract, including a mechanism for recovering costs associated with that contract. See Tex. Pub.

Util. Comm’n, Petition of Central Power & Light Co., West Texas Utilities Co. [AEP], and Southwestern Electric Power Co. for Approval of Contracts and Costs Associated with Renewable Energy Resources and for Authority to Implement a Power Cost Recovery Factor Associated Therewith, Docket No. 18845, Order (Nov. 23, 1998) (hereinafter “Settlement Order”). It is undisputed that costs incurred under the Wind Partners contract after commercial operations began (“post-commercial costs”) were to be recovered through a purchased power conservation factor (PPCF).2 However, the parties dispute whether the Settlement Order contemplated costs incurred before commencement of commercial operations of the Southwest Mesa Wind Farm (“pre- commercial costs”).3 The cities assert that AEP agreed to relinquish the right to recover pre- commercial costs and that these pre-commercial costs were not recoverable in the fuel reconciliation proceeding. AEP, on the other hand, argues that the Settlement Order contemplated only post- commercial costs and was silent on pre-commercial costs; pre-commercial costs would therefore be eligible for recovery through the fuel reconciliation proceeding.

Additionally, the cities contested the standard by which the Commission measured the efficiency of the Oklaunion plant.4 The Commission, in its preliminary order, indicated that it would consider the standard set forth in a previous docket in order to evaluate the efficiency of the

2 The parties essentially agreed in the Settlement Order that, because AEP would recover post-commercial costs through a PPCF, AEP’s fuel factor would be reduced as a result of the Wind Partners contract and AEP’s customers would receive a credit. See generally PURA § 36.203 (West 1998). The full details of the PPCF are not at issue in this appeal.

3 The pre-commercial costs AEP sought to recover totaled $745,530.

4 Only “reasonable and necessary” costs are recoverable. See 16 Tex. Admin. Code § 25.236(d)(1)(A) (2004).

Oklaunion plant. See Tex. Pub. Util. Comm’n, Application of West Texas Utilities [AEP] for Reconciliation of Fuel Costs, Docket No. 23477, Preliminary Order (July 13, 2001) (hereinafter “Docket No. 23477 Preliminary Order”); see also Tex. Pub. Util. Comm’n, Application of Southwestern Electric Power Company for Reconciliation of Fuel Costs, Surcharge of Fuel Cost Under-Recoveries, and Related Relief, Docket No. 17460, Preliminary Order (Aug. 22, 1997) (hereinafter “Docket No. 17460 Preliminary Order”). The cities assert that the Commission was required to determine the Oklaunion plant’s efficiency by comparing the Oklaunion plant to other coal plants in Texas. Conversely, AEP argued that the Commission should determine the Oklaunion plant’s efficiency by comparing the Oklaunion plant to similar coal plants throughout the United States.

An administrative law judge (“ALJ”) held a hearing on September 27, 2001 to review AEP’s request for fuel reconciliation, as well as the cities’ objections. AEP presented evidence in support of its request to include pre-commercial costs of the Wind Partners contract in reconcilable fuel. Additionally, AEP introduced evidence of its calculation of the efficiency of its Oklaunion plant using data from the North American Electric Reliability Council’s Generation Adequacy Data System (“NERC GADS”). The calculation based on the NERC GADS data produced an efficiency factor of 77.2 percent for the Oklaunion plant, compared with an efficiency factor of 72.1 percent for other coal plants throughout the country.5

According to AEP’s testimony before the Commission, AEP sought to “mazimiz[e]

utilization of [AEP]’s lower-cost coal generation to achieve the overall lowest reasonable fuel cost.” The cities assert that Oklaunion costs should not be recoverable if AEP was not operating the Oklaunion plant efficiently.

The cities also introduced evidence at the hearing before the ALJ. The cities introduced testimony that pre-commercial costs associated with the Wind Partners contract should not be allowed. Further, the cities introduced testimony that the efficiency of the Oklaunion plant should be determined by comparing the Oklaunion plant to other plants in Texas. The efficiency factor for other coal plants in Texas averaged 80.8 percent, compared to Oklaunion’s 77.2 percent.

On December 17, 2001, the ALJ issued a proposal for decision (“PFD”). In the PFD, the ALJ determined that AEP should not be permitted to recover the pre-commercial costs associated with the Wind Partners contract because those costs were required to be recovered through the separate PPCF.6 However, the ALJ determined that the NERC GADS standard proposed by AEP should be used to determine the plant’s efficiency. The ALJ further determined that AEP had prudently managed the Oklaunion plant and that costs associated with the plant should be approved.
