Virginia state law

State law can cap or override county rules. All Virginia rules and counties.

State siting: Virginia Department of Environmental Quality; State Corporation Commission

Projects up to 150 MW can use a permit by rule from the Department of Environmental Quality. Larger ones may need a certificate from the State Corporation Commission. Local approval is also needed.

Limits on local rules

For ground-mounted solar of 1 MW or more serving other property, counties must use a special exception or siting agreement whose setbacks, screening and height stay within state ranges; a county can still deny the application, and can depart from the ranges only by written agreement with the landowner and applicant.
