Dominion Energy Virginia announced Aug. 22 that it has broken ground on a solar and energy storage project at the Dulles International Airport.

Once completed, the Dulles Solar and Storage project will be the largest renewable energy project ever developed at a U.S. airport, Dominion said. It will generate up to 100 MW of solar energy and store up to 50 MW of power, enough clean energy to power more than 37,000 Virginia homes at peak output.

All the energy produced will serve Dominion Energy Virginia customers.

The partnership includes a first-of-its-kind lease agreement that will further advance renewables and electric vehicles at Dulles. Instead of annual lease payments to the Metropolitan Washington Airports Authority, Dominion Energy will develop two 1 MW solar carports that will partially power Dulles facilities, and provide 18 electric transit buses, 50 electric fleet vehicles and electric vehicle charging stations for Dulles operations.

In addition to utility-scale solar and battery storage, the project also includes two solar carports that will partially power Dulles facilities. (Artist rendering courtesy of Dominion Energy)

The project will be developed across 835 acres located in the southwest corner of Dulles International Airport. Construction will begin in late 2023 and is expected to be complete by late 2026. Construction of the project will support more than 300 jobs and $200 million in economic activity, Dominion said.

The project received final approval earlier this year after an extensive, multi-year review by the U.S. Department of Transportation, Federal Aviation Administration and Virginia State Corporation Commission, among other state and federal agencies.
