COLUMBUS, Ohio, Jan. 2, 2007 – American Electric Power (NYSE: AEP) announced today that its AEP Generating Co. subsidiary has agreed to purchase the Lawrenceburg Generating Station from an affiliate of Public Service Enterprise Group (NYSE: PEG) for approximately $325 million.

The transaction is contingent on the receipt of required regulatory approvals from the Federal Energy Regulatory Commission (FERC) and Indiana Utility Regulatory Commission. It also requires federal clearance pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976. The transaction is expected to close in the second quarter of 2007.

The Lawrenceburg plant, adjacent to AEP’s Tanners Creek Plant in Lawrenceburg, Ind., is a combined-cycle, natural-gas power plant with a generating capacity of 1,096 megawatts. The plant began commercial operation in June 2004.

“The purchase of the Lawrenceburg plant will provide additional generating capacity to meet the growing electricity demands of our customers at an attractive price,” said Michael G. Morris, AEP’s chairman, president and chief executive officer. "To meet an annual 2 percent growth in peak electricity demand in our eastern seven-state footprint and our reserve margin requirement in the PJM Interconnection, we must build new plants, like our Integrated Gasification Combined Cycle (IGCC) clean-coal generation projects in Ohio and West Virginia, and also seek opportunities to acquire recently completed gas-fired plants when the price is right. When the Lawrenceburg purchase is complete, we will have successfully added more than 2,900 megawatts of new natural gas-fired capacity to our generation fleet in two years at a significant discount to building equivalent capacity.

“The IGCC plants and our existing fleet of coal-fired plants in our eastern seven states will continue to supply the bulk of our customers’ demand and energy requirements on a daily basis,” Morris said. “The Lawrenceburg plant, along with the Darby acquisition announced in November 2006, and the Waterford and Ceredo plants purchased in 2005, will operate as mid-merit and peaking generation, designed for use when electricity demand is higher than average.”

When the transaction closes, AEP Generating Co. will own the Lawrenceburg plant, and AEP will operate the plant as part of the company’s generation pool that provides power to AEP’s utility units serving customers in Indiana, Kentucky, Michigan, Ohio, Tennessee, Virginia and West Virginia.

American Electric Power is one of the largest electric utilities in the United States, delivering electricity to more than 5 million customers in 11 states. AEP ranks among the nation’s largest generators of electricity, owning nearly 36,000 megawatts of generating capacity in the U.S. AEP also owns the nation’s largest electricity transmission system, a nearly 39,000-mile network that includes more 765 kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined. AEP’s utility units operate as AEP Ohio, AEP Texas, Appalachian Power (in Virginia and West Virginia), AEP Appalachian Power (in Tennessee), Indiana Michigan Power, Kentucky Power, Public Service Company of Oklahoma, and Southwestern Electric Power Company (in Arkansas, Louisiana and east Texas). The company is based in Columbus, Ohio.
