Old Dominion Electric Cooperative Announces Start Up of Wind Farm

Co-op to Receive 50% of Energy Output from AES Armenia Mountain, PA Facility

Glen Allen, Va. – Old Dominion Electric Cooperative (ODEC) and AES Wind Generation, a wholly-owned subsidiary of The AES Corporation, have announced the start of commercial operation of the Armenia Mountain wind farm in Pennsylvania.

ODEC, the primary power provider for 11 electric distribution cooperatives in Delaware, Maryland and Virginia, will receive 50 percent of the electricity generated by the 101 megawatt (MW) wind farm which is located in the Pennsylvania counties of Bradford and Tioga in the north central region of the Keystone State.

AES Wind Generation developed, owns and operates the wind farm which is comprised of 67 1.5 MW GE SLE wind turbines.

“We are delighted to announce that the Armenia Mountain wind farm is up and running and producing renewable electricity to serve our member distribution cooperatives and their over 500,000 consumer-members throughout the Mid-Atlantic,” said Jackson E. Reasor, ODEC president and CEO. “Our contract for the wind-generated energy from this project is part of ODEC’s long-term plan to further diversify our power supply portfolio to include a variety of economically-viable conventional and renewable generation resources, such as the Armenia Mountain wind farm.”

“We also wish to congratulate AES Wind Generation on their successful completion of this exciting project and look forward to its continued successful operation,” Reasor added.

“We’re pleased to provide wind power to Old Dominion Electric Cooperative,” said Marty Crotty, president of AES Wind Generation. “We hope that the Armenia Mountain project is the first of several opportunities to work together to deliver affordable and sustainable energy.”

In July 2008, ODEC signed a 15-year power purchase agreement with AES Wind Generation for 50 percent of the output of its then planned Armenia Mountain Wind Farm project. A separate agreement for 50 percent of the energy output from the wind farm was signed by Newark, Del.-based Delmarva Power. AES Wind Generation was chosen as one of the winning bidders following a request for proposals from wind generated power providers issued in early 2008.

In addition to its contract with AES Wind Power for 50 percent of the output from the Armenia Mountain Wind Farm, ODEC’s portfolio of renewable generation resources also includes 100 percent of the power generated from a landfill gas-to-energy project in Worcester County, Md. and a hydroelectric project in Bath County, Va. ODEC has also signed a long-term agreement to purchase the 70 MW of energy projected to be produced by the Constellation Energy Criterion Wind Power Project to be built in Garrett County, Md.
