The Potomac Edison Company

Potomac Edison's EV charger time-of-use rider is the main tool for EV owners who want to cut charging costs, and it applies only to Maryland customers. It is an EV-only rider rather than a whole-home EV rate: drivers who charge a smart, connected Level 2 charger overnight save 2 cents per kWh off the Electric Supply Charge during off-peak hours, which run 11 p.m. to 6 a.m. on weekdays plus all weekends and six holidays. Charging during on-peak hours adds 2 cents per kWh instead. The rider rewards drivers who can shift charging to overnight and weekends, and it cannot be combined with the general residential time-of-use rate.

The residential $300 Level 2 charger rebate runs through the same EV Driven pilot, but it has reached its funding cap and is not accepting new applications. Multifamily property owners can still apply for a rebate covering 50 percent of installation cost up to $20,000 for Level 2 or DC fast chargers, or instead take a utility-owned option in which Potomac Edison installs, owns, and maintains up to seven Level 2 stations at no equipment cost. Maryland Energy Administration rebates can stack with EV Driven rebates.

Potomac Edison serves western Maryland and the West Virginia Eastern Panhandle, but its EV Driven programs exist only in Maryland because they were approved by the Maryland Public Service Commission. West Virginia customers have no Potomac Edison EV-specific rate or charger rebate. Maryland is a deregulated supply state, so the rider discount applies to the utility-default Electric Supply Charge; customers who buy power from a competitive third-party supplier should confirm how the rider interacts with their contract before enrolling.
