COLUMBUS, Ohio, Sept. 7, 2004 - American Electric Power (NYSE: AEP) subsidiary AEP Texas Central Company (formerly known as Central Power and Light) has signed an agreement to sell its 25.2 percent share of the South Texas Project (STP) nuclear plant to STP co-owners Texas Genco Holdings, Inc. (NYSE: TGN) and City Public Service Board of San Antonio (CPS) after the co-owners exercised their rights of first refusal for the AEP Texas Central Company (TCC) share of STP.

Texas Genco Holdings will purchase 13.2 percent of STP for approximately $174 million. CPS will purchase 12 percent of STP for approximately $158 million. When the transactions are complete, Texas Genco Holdings will own 44 percent of STP, and CPS will own 40 percent of STP. The City of Austin elected not to exercise its right of first refusal for the TCC share of the plant and will continue to own 16 percent of STP. STP is operated by STP Nuclear Operating Company. AEP will use the proceeds from the sale to reduce debt.

AEP had announced a purchase agreement with Cameco Corp. for the TCC share of STP March 1. The terms and conditions of the new purchase agreements signed with Texas Genco Holdings and CPS will remain essentially the same as the agreement signed with Cameco. AEP will pay a $7 million break-up fee to Cameco upon termination of the Cameco purchase and sale agreement due to the right-of-first-refusal exercise.

The sale of STP to the co-owners is subject to regulatory approvals including federal clearance pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and approvals from the Nuclear Regulatory Commission, Federal Energy Regulatory Commission, and Securities and Exchange Commission. AEP hopes to close the transaction in late 2004 or early 2005.

“We are pleased to have reached an agreement with the co-owners of STP and will be working diligently to complete the approval process as soon as possible. We also continue to prepare to file for stranded cost recovery as soon as we close the TCC sale transactions,” said Charles Patton, AEP Texas president and chief operating officer.

STP is a 2,500-megawatt nuclear plant located in Matagorda County, Texas, approximately 90 miles southwest of Houston. TCC’s 25.2 percent share of the plant is approximately 630 megawatts.

AEP announced plans in December 2002 to sell all 4,497 MW of the generation assets owned by TCC to determine their market value for calculating stranded costs (the amount that the book value exceeds the market value of the assets) under Texas restructuring legislation. AEP completed sale of 3,813 MW of these generating assets, including eight natural gas plants, one coal-fired plant and one hydro plant, to a joint venture of Sempra Energy Partners and Carlyle/Riverstone Global Energy and Power Fund July 1. AEP continues to work toward completing the sale of TCC’s 7.8 percent share of Oklaunion Plant.

American Electric Power owns more than 36,000 megawatts of generating capacity in the United States and is the nation´s largest electricity generator. AEP is also one of the largest electric utilities in the United States, with more than 5 million customers linked to AEP’s 11-state electricity transmission and distribution grid. The company is based in Columbus, Ohio.
