Delmarva Power

Delmarva Power serves two regulatory territories, and the EV programs differ by state. In Delaware, the only residential incentive is the Plug-In Vehicle (PIV) rate: a time-of-use rate for EV charging with on-peak hours from noon to 8 pm on weekdays, excluding holidays, and off-peak at all other times. It needs a second 200-amp meter socket and a second utility meter, so the cost of that equipment sits on top of the savings, and customers with a third-party electricity supplier are not eligible. In Maryland, customers can choose the Whole House TOU rate or the EV-TOU program, which keeps the rest of the home on the standard rate with no separate meter. The Whole House rate uses the same noon-to-8-pm weekday peak window for the whole home and requires a plug-in vehicle that can travel at least 30 miles on electricity alone.

Delmarva's charger rebates are closed. The Maryland residential smart-charger rebate, the PIV Managed Charger Program, and the Workplace Charger Rebate for Maryland small businesses and nonprofits no longer accept applications. Maryland customers can still earn up to 120 dollars per year through Smart Charge Management, which pays 10 dollars per month per enrolled vehicle with a Level 2 charger or per enrolled Level 2 charger, and 5 dollars per month per vehicle on a Level 1 charger, and up to 240 dollars per year when paired with the EV-TOU program. For businesses, Delaware's state rebate program covers up to 75 percent of station and installation costs for multi-family, public-access, fleet, and workplace projects, with caps of 5,000 dollars per single-port or 10,000 dollars per dual-port charger and, for multi-family sites, 75,000 dollars per site.

Delmarva Power is a wires-only distribution utility operating in a retail-choice environment in both Delaware and Maryland, meaning it delivers electricity but does not set the commodity supply rate for most customers. Because the Delaware PIV rate applies to the supply portion of the bill, and the Maryland rates require customers to be off third-party supply, the savings are separate from whatever supply rate a customer has chosen. Delaware is also in the PJM Interconnection footprint, which means regional capacity and energy market conditions influence total bills in ways that differ from vertically integrated utility states.
