Time-of-use rate wiring: EV chargers, heat pumps, and appliances on Vermont's electric rate

It is an optional residential rate (Rate 11) charging a Customer Charge of $0.830 per day plus $0.34072 per kWh during Peak Hours and $0.14522 per kWh during Off-Peak Hours, as published in GMP's tariff effective with bills rendered on or after October 1, 2025. Peak Hours are a period of eight consecutive hours between 1:00 p.m. and 9:00 p.m., Monday through Friday; all other hours are Off-Peak. Confirm the current version at greenmountainpower.com/rates/ before switching, since a rate schedule can be revised.

Switching the rate itself is a request to the utility, not an electrical project. The electrical work comes in afterward, if at all: whether your EV charger, heat pump, or other large equipment can actually be scheduled to avoid the roughly eight-hour weekday peak window, which for equipment with no built-in scheduling means adding a timer or smart control.

Many modern EV chargers have app-based scheduling built in and need no additional wiring: check the specific charger's own capability first. Older or simpler chargers may need an added smart breaker or timer to accomplish the same thing, which is an electrical addition rather than a settings change.

Often yes for the compressor cycle, but a heat pump maintaining comfort during a Vermont winter has real limits on how long it can be off before the space cools noticeably. This is a design question for the specific system and thermostat, not a blanket answer. Confirm with the installer what interruption the equipment and its controls actually tolerate before relying on it for savings.

That is a math and behavior question the rate schedule above can answer directly, if most of your usage happens during the roughly eight-hour weekday peak window and can't realistically move, the standard rate may cost less. For billing questions, ask Green Mountain Power or your utility; the electrical side of shifting a load is what an electrician can tell you, once you've decided to try it.

Yes, and on a property adding an EV charger, a heat pump, and other load at the same time, sequencing them (so they don't all draw at once even during cheaper hours) is a load-management design question worth raising with the electrician rather than assuming each device will coordinate itself.

Rate structures differ by utility, and BED or VEC customers do not necessarily have the same time-of-use terms GMP publishes. Confirm directly with the utility serving your address before assuming a schedule built around GMP's peak window applies to you.
