Where Public Service Co of NH sits

It is the dominant supplier in New Hampshire, serving 279,131 residential customers, so its pricing effectively sets what the state average looks like. At 22.65¢ per kilowatt-hour it is one of the cheaper places to buy electricity in New Hampshire, 17.1% under the statewide average of 27.33¢.

Its customers use very little electricity by national standards, 601 kilowatt-hours a month against 871 nationally. Dense housing, a mild climate or heating that runs on gas rather than electricity all push consumption down, and any of them can leave a household with a modest bill despite a high rate.

A shareholder-owned company whose rates are set by the state regulator, including an approved return on the capital it has invested. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

Optional rate plans

Public Service Co of NH offers time-of-use pricing to residential customers. 85 households were enrolled, about 0.1% of its residential base.

These plans are opt-in almost everywhere. They reward households that can move laundry, dishwashing, water heating or electric vehicle charging out of the late-afternoon peak, and they cost more than the standard rate for households that cannot. How to tell which group you are in.

Rooftop solar on this system

16,580 residential customers had net-metered solar in 2024, totalling 133.41 megawatts. That works out to 59.4 installations per thousand customers, against a median of 8 across the utilities reporting it.

Adoption here is exceptionally high. That usually means some combination of a high retail rate worth displacing, strong sunshine and favourable export rules, and it tends to bring its own regulatory argument about who covers the fixed cost of the network. What exports are actually worth.
