~Using renewable energy saves money, supports county’s climate goals~

FAIRFAX, Va. – A rooftop solar system that will save energy costs and reduce carbon emissions the same amount per year as recycling the contents of nearly five garbage trucks full of waste has been installed by the Department of Public Works and Environmental Services at its Newington Collections Facility in Lorton.

The 150-kilowatt solar photovoltaic array is the first on a DPWES facility but represents another step in achieving the Fairfax County’s Operational Energy Strategy. The project is being installed using funds dedicated to advancing solar at County facilities and will cost $543,000 but is expected to generate more than $19,000 in savings annually. It also is eligible for a federal tax credit and should generate savings to offset the cost within 19 years.

In 2023 DPWES rolled out two electric refuse trucks – a move that will also save on fuel costs and protect the environment. Two charging stations were also installed at the Newington facility in Lorton, where the solid waste collection trucks are based. DPWES is also working on installing a 5-megawatt array at the I-95 Landfill Complex and a rooftop system at the I-66 Transfer Station.

“Solar isn’t just a reliable source of energy – it’s better for the environment and for our operating budget,” said Eric Forbes, Deputy Director for DPWES Solid Waste Management. “The energy from these solar panels will provide nearly 76% of the building’s power needs and reduce the carbon emissions by 91 metric tons. That’s the equivalent of removing 22 cars off the road. Or in our case, it’s the same as recycling 32 tons of trash instead of taking it to a landfill.

The Operational Energy Strategy has set a goal for carbon neutrality in its facilities, fleet vehicles and county operations, including 50% of county electricity from renewable sources, by 2040. Five county buildings were equipped with solar panels in 2023 and more than a dozen solar projects are planned in 2024. CMTA provided engineering and construction management services for the project, and Mountain View Solar did the installation.
