The Virginia Department of Environmental Quality has awarded developer Apex Clean Energy a "permit by rule" for the 25-turbine project.
The Rocky Forge Wind site is planned for an area of rural land in Botetourt County, northern Virginia.
"Competitive pricing and clear evidence that new clean energy generation attracts major corporate investment, Rocky Forge Wind is set to begin a new chapter in Virginia's energy future," said Apex CEO Mark Goodwin.
The developer said it had already received approval at all levels of local permitting as well as the endorsement of the local chapter of the Sierra Club, the Virginia Deer Hunters Association, and the Virginia Conservation Legacy Fund, among other groups.
Apex has developed 1.46GW of renewable energy projects in the US since 2015.
There is now wind capacity in 40 US states, providing approximately 5% of the nation's electricity.
