Why Virginia Needs Backup Power
Virginia faces hurricanes and nor'easters on the coast, ice storms in the mountains, and severe thunderstorms statewide. Northern Virginia's proximity to DC means higher labor costs but also strong installer availability.
Hurricane Helene (2024) and prior nor'easters have left hundreds of thousands of Virginians without power, particularly in coastal Hampton Roads and mountainous western regions. Power in Virginia is served by Dominion Energy Virginia, Appalachian Power, Northern Virginia Electric Cooperative. According to the Virginia State Electricity Profile, the state averages 2.5 outages per year with a mean duration of 7.5 hours per event.
