What does Prince William County need for an EV charger permit?
The county has its own residential EV charging page, and it is the rulebook for Potomac Mills. A charger that plugs into an existing outlet that meets the maker's instructions needs no permit. A hard-wired charger, or any new or extended circuit to feed one, does.
The plan review is a walk-through review with no plan review filing fee. For a charger rated over 20 amps, the county also wants a Residential Load Calculation Worksheet, with the charger counted at 125% of its nameplate rating. The worksheet and the maker's instructions must be on site for the inspector.
Owners may apply and do the work on their own home. In that case the county asks for a Statement of Exemption. Contractors show a Virginia contractor's license and a county business license.
Dominion program or NOVEC rate: which fits your Potomac Mills home?
It depends on who sends your bill. Most Potomac Mills homes sit in Dominion Energy territory, and the area around the mall and Smoketown Station is NOVEC, per the federal service territory map.
Dominion's Residential Charger Program installs an approved charger for a monthly fee. It only takes free-standing single-family homes, with the charging spot within 30 feet of the main panel. Its income-qualifying option is fully subscribed.
NOVEC does not list a charger rebate. It offers the EV-1 rate for members who own or lease an EV, with off-peak hours from 11 p.m. to 6 a.m. A charger with a timer makes that rate easy to use.
Townhouses, condos and electric heat
About 21% of Potomac Mills homes are townhouses and about 16% are in buildings with 10 or more units (Census ACS). Those homes do not fit Dominion's program, so the usual path is a charger on its own new circuit. In a condo, the spot and the wire route are often shared space, so check with your association before we plan the run.
The other local factor is heat. About 73% of homes here heat with electricity. A 48 amp charger counted at 125% is a large load next to a heat pump with backup strips. The load worksheet the county asks for answers whether the panel can carry both. If it cannot, a panel upgrade or a load management device comes first.
