RICHMOND, Va. - Dominion (NYSE:D), one of the nation's largest energy suppliers, will provide generation service to approximately 250,000 residential customers in PECO Energy's Philadelphia service area through a Market Share Threshold process approved by the Pennsylvania Public Utility Commission.

"We welcome Philadelphia area residents to the growing family of Dominion customers," said Thos. E. Capps, Dominion's chairman, president and chief executive officer. "The only difference they will see under this program is a lower electricity bill."

Dominion will notify by mail the customers randomly selected for the program. Generation service will begin December 1 and customers will get a discount on the generation portion of their PECO bill.

Dominion will provide the electricity, but PECO will continue to deliver it to homes. Also, PECO will continue to provide one bill and be responsible for emergency response, wires to the home, meter reads, bill payment and related services.

Dominion will now have more than 5.2 million customers, including nearly 1 million in Pennsylvania. Dominion owns a natural gas utility serving western Pennsylvania, a 600-megawatt power station in Armstrong County and is building a 1,200-megawatt power station in Bucks County.

"Adding new energy customers is a part of our integrated strategy and will provide a home for our electricity generation," Capps said.

Dominion is one of the nation's largest producers of energy, with a diversified and integrated energy portfolio that includes more than 24,000 megawatts of generation and 6.3 trillion cubic feet equivalent of proved natural gas reserves.
