Maryland Utilities Ramp Up Investment in Electric Vehicle Charging Infrastructure

Maryland's major electric utilities are significantly increasing investment in public and workplace electric vehicle charging infrastructure, filing new rate cases with state regulators to fund expansion ahead of state emissions reduction targets that anticipate a substantial increase in electric vehicle adoption over the coming decade.

The investment plans would add thousands of new charging ports across the state, with particular emphasis on multifamily housing developments and workplaces where residents and employees currently lack convenient access to home charging, a gap utility officials say has become one of the primary barriers to electric vehicle adoption among renters.

"Homeowners with a garage can install a charger without too much difficulty, but a huge share of Marylanders live in apartments or condos where that's just not an option right now," said a utility executive overseeing the charging infrastructure investment. "If we don't solve charging access for that group, we're not going to hit the adoption numbers the state is planning around."

The proposed investments would be recovered gradually through utility rates, a funding mechanism that has drawn some pushback from consumer advocates who argue that non-electric-vehicle-owning ratepayers should not subsidize charging infrastructure primarily benefiting a smaller group of current EV owners. Utility officials countered that broad electrification benefits the grid over the long term by increasing overall electricity demand and utilization.

State energy regulators are reviewing the rate case proposals and are expected to issue a decision within the next several months. Clean energy advocacy groups have generally supported the investment plans, arguing that charging infrastructure gaps remain one of the most significant obstacles to Maryland meeting its transportation electrification goals.
