Green Mountain Power Corporation

Green Mountain Power's residential EV rates are the main tool for EV owners who want to cut charging costs, and GMP offers two of them. Rate 74 is a time-of-use plan where peak hours run Monday through Friday from 1 p.m. to 9 p.m. and everything outside that window is off-peak, so charging overnight costs less than charging during the afternoon and evening peak. Rate 72 is an off-peak EV rate paired with the standard residential Rate 1, where GMP manages charging during a handful of monthly peak events and customers can opt out of any event. Both reward shifting charging away from the late-afternoon peak.

The rebates stack with the rates. GMP's free in-home Level 2 charger comes with enrollment in its managed home charging program, which is the same program that powers the off-peak rate, so the charger and the rate work together rather than separately. EV buyers can also claim a purchase rebate, up to $2,500 for income-eligible customers on an all-electric vehicle, plus a $500 check for connecting an eligible charger and enrolling in a discount charging rate. These are GMP programs and are separate from Vermont's statewide EV purchase incentives.

GMP is a single-state, investor-owned utility regulated by the Vermont Public Utility Commission, and Vermont is not a deregulated electricity market, so GMP both delivers power and sets these retail rates and rebates directly. Drive Electric Vermont coordinates EV adoption statewide but is not the source of GMP's utility programs; the incentives described here are GMP's own and apply only at GMP service addresses in Vermont.
