FOR IMMEDIATE RELEASE

Allegheny Power Files Rate Petition in Pennsylvania

Greensburg, Pa., September 7, 2004 – Allegheny Power, the delivery unit of Allegheny Energy, Inc. (NYSE: AYE), today filed with the Pennsylvania Public Utility Commission for approval to facilitate the recovery of stranded costs and provide rate certainty for its more than 690,000 electric customers in Pennsylvania through an extended transition to competition. The Office of Consumer Advocate, the Office of Small Business Advocate and The West Penn Power Industrial Intervenors joined in the filing.

“We believe this extension of rate caps will provide customer rate protection and a smooth transition to competitive market-based rates,” said Paul J. Evanson, Chairman and Chief Executive Officer, Allegheny Energy, Inc. “Allegheny hasn’t increased rates in a decade, and our customer rates are among the lowest in Pennsylvania.”

Highlights of the filing include:

• Extension of the distribution rate caps for an additional two years through 2007 for all Pennsylvania retail customers.

• Extension of generation rate caps for an additional two years through 2010, with additional generation rate increases in 2007, 2009 and 2010. Allegheny’s 1998 restructuring agreement previously provided for rate increases in 2006 and 2008. Between the 1998 restructuring agreement and the amended agreement proposed today, average unit rates for residential customers will gradually increase from 6.79 cents per kilowatt-hour (kWh) in 2005 to 7.13 cents per kWh in 2006, 7.49 cents per kWh in 2007, 7.86 cents per kWh in 2008, 8.81 cents per kWh in 2009 and 9.09 cents per kWh in 2010.

• Securitization of approximately $115 million of stranded costs.

The new customer rates would enable Allegheny Energy to realize generation prices of approximately $30.10 per megawatt-hour (MWh) for 2005, $32.80 per MWh for 2006, $35.50 per MWh for 2007, $38.30 per MWh for 2008, $46.90 per MWh for 2009 and $50.80 per MWh for 2010 before moving to market prices. Under the current agreement, generation prices are approximately $30.10 per MWh for 2005, $32.80 per MWh for 2006 and 2007 and $35.40 per MWh for 2008 before moving to market prices.

Allegheny’s request will go before an administrative law judge, who will make a recommendation to the Commission for further action. Headquartered in Greensburg, Pa., Allegheny Energy is an integrated energy company with a portfolio of businesses, including Allegheny Energy Supply, which owns and operates electric generating facilities, and Allegheny Power, which delivers low-cost, reliable electric and natural gas service to about four million people in Pennsylvania, West Virginia, Maryland, Virginia and Ohio.
