Fortistar has launched an expanded 4.8 megawatt landfill gas-to-energy facility in Prince William County, Va.

The White Plains, N.Y.-based energy company said in a news release the facility expands its current 1.9 megawatt facility at the site, at the county landfill in the Coles Magestrial District. The facility will provide between 4,000 to 5,000 Northern Virginia Electric Cooperative (NOVEC) customer homes with renewable power.

Fortistar built, owns and operates the landfill gas-to-energy facility.

A portion of the proceeds are returned to the county as royalties, thereby lowering the landfill’s operational costs.

The Prince William County Solid Waste Division provides waste and recycling service to more than 400,000 residents.
