Wind EnergyFor more than a decade, ODEC has been partnering with private developers to add more than 260 MW of wind generation. In 2008, ODEC executed an agreement to buy 50% of the output of AES Corporation’s Armenia Mountain Wind project in Bradford and Tioga counties in north central Pennsylvania. The project began commercial production in December 2009, with the completion of 67 General Electric 1.5 MWs SLE wind turbines that can produce 100.5 MWs.

In 2009, ODEC executed its second wind power agreement to buy the entire output from Criterion Wind Project located in Garrett County, Maryland. The 70.0 MW project employs 28 Clipper 2.5 MW Liberty turbines and began commercial operations in 2010.

ODEC executed a third contract with E.ON’s Stony Creek Wind Farm, which is currently in operation in Somerset County, Pennsylvania. ODEC purchases capacity, energy and renewable energy credits from this 32.5 MW facility.

ODEC’s latest wind contract is with BP Wind Energy’s Mehoopany Wind Farm in Wyoming County in northeastern Pennsylvania. ODEC began buying over 110 MW of capacity, energy, and renewable energy credits from the project after it began commercial operations in January 2013.

Solar EnergyIn 2017, ODEC entered into two long-term power purchase agreements to buy solar power from separate projects owned by Dominion Generation (a subsidiary of Dominion Energy). The Clarke County Solar project is a 10 MW solar power facility in Clarke County, VA located in Rappahannock Electric Cooperative’s service territory. The Cherrydale Solar Project is a 20 MW solar power facility in Northampton County on Virginia’s Eastern Shore in A&N Electric Cooperative’s service territory. Both projects began commercial operations in 2017.

In 2018, ODEC entered into a long-term power purchase agreement to buy solar power from the Cabin Point Solar Facility in Sussex County, VA. This project is expected to be a 75 MW solar power facility, with an anticipated commercial operations date in 2022.

ODEC is actively exploring additional solar opportunities, and issued a Request for Proposals in early 2019.

Landfill EnergyODEC currently buys the output of a landfill gas-to energy project in Henrico County, Virginia. This project produces electricity by collecting naturally occurring methane, a byproduct of decomposing waste, and burning it to produce power via an electric generator. The Henrico County Project totals approximately six MWs of capacity.

Using methane from landfills not only creates electricity from a renewable fuel source, it reduces the net emissions of greenhouse gases from the landfill.
