The 100MW solar energy project is the Airports Authority’s first large scale renewable energy initiative of this kind.
The project will power the Dulles Airport and connect to Dominion’s transmission line to provide energy to commercial and residential consumers in Virginia’s most populous region.
The solar facility is expected to power more than 24,000 homes and is expected to be one of the largest solar facilities in Northern Virginia.
The facility is expected to come online before 2023 as part of plans by Dominion Energy to reach 3,000MW of wind and solar in operation and underdevelopment by 2022.
The utility has plans to expand its portfolio of renewables to be able to reduce its carbon emissions by 55% by 2030.
Keith Windle, vice president of business development & merchant operations at Dominion Energy, said: "We are thrilled to partner with the Metropolitan Washington Airports Authority on this ambitious, renewable energy project. More than 24 million passengers flying through Dulles each year will witness the sun's energy being used to generate clean energy for Virginians.
"Partnering with Dominion Energy on this important project will give us the data and tools we need to determine the role that solar energy can play at a major international airport now and in the future," adds Mike Stewart, airport manager, Dulles International Airport. "This project fits well with the Airports Authority's goal of enhancing the sustainability and environmental performance of our facilities."
