Scheduled to be built near the Remington Power Station in Fauquier County, the 20MW project will feature approximately 90,000 photovoltaic panels and at peak capacity would generate enough electricity to provide power for 5,000 homes.
Dominion Resources chairman, president and chief executive officer Thomas Farrell II said: "The Remington Solar Facility marks the beginning of an exciting process with large scale solar technology that adds emission-free generation in the Commonwealth.
"Increasing our use of solar energy is part of that plan, and renewable energy will play an increasingly important role in Virginia’s future. Dominion has diversified the type of fuels it uses to generate electricity with more use of natural gas and biomass generation."
The project is expected to be commissioned is October 2016.
Virginia Governor Terry McAuliffe said: "I want to thank Dominion for their commitment to solar energy development with a project that nearly doubles Virginia’s production of solar energy.
"I look forward to working with them to continue to expand renewable generation in Virginia and diversify the Commonwealth’s fuel mix."
