This bill requires Virginia local governments to review potential impacts before approving new data centers using 100 megawatts or more of electricity. Applicants must submit a site assessment studying noise and effects on nearby homes and schools within 500 feet. Localities may also request reviews on water, farmland, parks, historic sites, and forests. The serving utility must disclose substations and voltage. These requirements help local governments make informed decisions that fit community plans and zoning rules. Expansions under 100 megawatts are exempt.
