Delmarva Power’s Delaware Customers to Benefit from 38-Megawatt Facility

WASHINGTON – Pepco Holdings, Inc. (NYSE:POM) announced its subsidiary Delmarva Power will receive 38 megawatts (MW) of wind energy and associated renewable energy credits from the recently completed Chestnut Flats wind facility in south central Pennsylvania. The 38-megawatt land-based wind farm is owned by enXco, an EDF Energies Nouvelles Company.

Delmarva Power signed a 20-year Power Purchase Agreement in 2008 for land-based wind power as part of its renewable energy portfolio for meeting Delaware’s clean energy goals, which require 25 percent of the company’s energy supply to come from clean sources by 2025. The 38-megawatt Chestnut Flats wind farm is located in Logan Township, Blair County, northwest of Altoona, Pa. The project features 19 wind turbines, manufactured by Gamesa, each having two megawatts of rated capacity.

“The Chestnut Flats wind farm is the third of our land-based wind procurements to come online,” said Gary R. Stockbridge, Delmarva Power Region President. “This is another example of working regionally to make a difference in delivering clean, green energy. We support renewable standards, and we recognize it takes a long-term plan to achieve these ambitious goals.”

Delmarva Power will purchase 100 percent of Chestnut Flats’ output.
