Clarke County Solar

White Post, Virginia

United States


Technical details

Solar projects have sprouted in rural areas across Virginia, thanks partly to the state’s regulatory process, which puts local officials in control of permitting decisions. Clarke County Solar, which began producing electricity in 2017, shows how local authorities have worked with solar developers for mutual advantage.

Clarke County Solar is a 10-megawatt solar array at Double Tollgate, an unincorporated community just west of a slightly larger town called White Post. The name came from an octagonal white signpost in the center of the Berry’s Ferry Road-White Post Road intersection. Tradition has it that an ambitious teenage surveyor erected the post in 1750. His name was George Washington.

The project developer liked the Double Tollgate location because an existing substation allowed easy connection to the electrical grid. The Clarke County Board of Supervisors gained additional revenue, including an annual tax payment of $20,992 for 25 years. Old Dominion Electric Cooperative, headquartered in suburban Richmond, Virginia, acquired a long-term source of renewable energy.

Cloverly purchased 250 Renewable Energy Credits from the project, issued during April 2019. Renewable Energy Credits are also called renewable energy certificates or RECs. Each REC certifies that 1 megawatt-hour of electricity has been generated by renewable means and delivered to the electric grid. RECs represent the rights to all of the environmental benefits of generating energy by clean, renewable means. Buying them helps fund solar farms and other renewable-energy projects.
