Unitil Energy Systems, Inc.

Unitil's EV-specific time-of-use delivery rate, Schedule TOU-EV-D, is the main tool for New Hampshire residential customers who want to cut charging costs. It meters EV charging separately from the rest of the home and splits weekdays into three windows: off-peak from 8 p.m. to 6 a.m., mid-peak from 6 a.m. to 3 p.m., and on-peak from 3 p.m. to 8 p.m. All weekend and weekday-holiday hours bill at the off-peak price. Charging overnight is where the rate pays off; drivers who must charge during the late-afternoon on-peak window will save less.

The EV time-of-use rate is the main EV-specific offer here, and it does not stack with a New Hampshire charger rebate, because Unitil does not have a confirmed New Hampshire residential or commercial EVSE rebate. The Ready2Charge rebates Unitil advertises, up to $700 for installation and up to $1,700 for income-eligible customers, are filed for its separate Massachusetts operating company and do not apply in New Hampshire. The EV rate uses a separate dedicated meter that an electrician wires and Unitil installs, with a one-time setup fee and a small monthly meter charge, and customers commit to a 12-month term.

New Hampshire runs a restructured electricity market, so Unitil delivers power over its wires while energy supply is competitive or taken as default service. The time-of-use price signal applies to Unitil delivery charges, and these EV delivery charges reset each June 1 and December 1, so the gap between off-peak and on-peak shifts over the year. In May 2022 the state regulators rejected a Unitil New Hampshire EV make-ready proposal, which is why no New Hampshire commercial make-ready rebate is asserted on this page.
