The Metropolitan Washington Airports Authority and Dominion Energy Virginia have agreed to jointly study the development of a 100MW solar energy project at Washington Dulles International Airport.
Dominion Energy recently signed a sublease with the Airports Authority for the feasibility studies, which will move the project forward.
To be spread over 1,200 acres, the solar farm could power up to 25,000 homes at peak output.
It will become the biggest solar facility in the northern region of Virginia when operational in 2023.
The generated electricity will be delivered to commercial customers via Dominion Energy’s existing transmission line on the airport property.
Dulles International Airport manager Mike Stewart said: “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.
“This project fits well with the Airports Authority’s goal of enhancing the sustainability and environmental performance of our facilities.”
Dominion Energy expects the solar project to help the company reach its goal of lowering CO2 emissions by 55% in 2030.
Dominion Energy business development and merchant operations vice-president Keith Windle 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.”
Last month, a total of $854,786 was granted to Washington Dulles International Airport from the US Department of Transportation (DOT) to support Voluntary Airport Low Emissions (VALE) infrastructure.
