Business & Energy Editors

GREENSBURG, Pa.--(BUSINESS WIRE)--Dec. 22, 2000

The energy supply subsidiary of Allegheny Energy, Inc. (NYSE:AYE), Allegheny Energy Supply Company, LLC, today announced it would consolidate and move nearly 300 core business employees to a state-of-the-art facility in the Pittsburgh suburb of Monroeville, Pa.

The move exemplifies the growth and transition of the Company as it moves from a regional entity to a national energy supplier.

"This is an exciting time for our Company," said Peter J. Skrgic, President, Allegheny Energy Supply. "In addition to announcing generating projects that will increase our total generating capacity to more than 12,000 megawatts (MW) - plus the many other projects under consideration -- we have found a first-class location for our corporate center which embodies the growth and expansion of our business."

Administrative offices of both the Projects Division and the Production & Sales Division of Allegheny Energy Supply, along with key support services, will be combined in the new office space in the Westinghouse Energy Center in Monroeville. Currently, the two divisions are housed in separate locations in Greensburg. Allegheny Energy Supply plans to move into the new facility in March 2001.

In addition to being a state-of-the-art facility, the Energy Center gives Allegheny Energy Supply greater access to a major city and its large and diversified work force for additional employees to support the Company's expected growth.

"Not only does this move give us growing space, but it also puts us close to the major city in this region and all of the resources that it has to offer," said Skrgic. "Additionally, Pittsburgh is one of our key markets, and we remain committed to the community and the region."
