Why New Hampshire pays what it pays
New Hampshire buys most of its power from the same ISO New England pool as the rest of the region, so it inherits the regional constraint: a marginal generation fleet dominated by natural gas, fed by pipelines that fill up in cold weather. The state's own generation mix is unusual for New England, since the Seabrook nuclear station alone supplies a large share of in-state output. That plant sells into the regional market, though, rather than serving New Hampshire ratepayers at cost.
The visible driver of recent movement is the default-service reset. Utilities procure default supply in six-month terms, and each reset republishes the market's view of forward gas prices as a step change in the residential rate. That mechanism makes New Hampshire look jumpy next to regulated states that smooth costs across a full rate case.
Where New Hampshire power comes from
New Hampshire generated 19 TWh in 2025, the 44th largest output of any state. Nuclear supplied 56.4% of it, enough that the price of that fuel largely sets the price of electricity here. Renewables accounted for 12.9%, against 23.8% nationally, which ranks New Hampshire #33 of 51.
- Nuclear 56.4% 11 TWh
- Natural gas 27.5% 5 TWh
- Hydroelectric 7% 1 TWh
- Wood and biomass 3.4% 655 GWh
- Wind 2.5% 476 GWh
- Coal 1.2% 239 GWh
- Petroleum 0.9% 182 GWh
- Other 1% 197 GWh

Heating in New Hampshire: gas, heat pump or resistance
Residential natural gas in New Hampshire averaged $18.74 per thousand cubic feet in 2024, about $1.81 per therm, against a national average of $14.50. Put on the same scale as the state's electricity rate, the cost of delivering one million BTU of heat works out as follows.
In New Hampshire, gas remains cheaper to run than a heat pump by about $6.62 per million BTU at these assumptions, roughly $397 over a 60 million BTU season. A heat pump can still be the better purchase once cooling, equipment age and incentives are counted, but not on heating cost alone.

Who sells electricity in New Hampshire
Eversource is the largest distribution utility, with Liberty Utilities and Unitil covering other territories. New Hampshire has full retail choice, and it also has one of the more active municipal aggregation movements in New England. A number of towns and cities buy supply collectively on behalf of residents who do not opt out.
Aggregation contracts are negotiated locally and signed at different times, so two households a few miles apart can pay noticeably different supply rates while sharing an identical delivery charge.
New Hampshire sits in New England. Six states sharing one constrained gas pipeline network, which sets the winter price for all of them. Read the regional analysis.
What you can actually do about it
If your community runs an aggregation programme, compare the aggregation price against the utility default-service price at every reset. Neither is permanently cheaper. Both are procurement outcomes, and which one wins depends on when the contract was signed.
New Hampshire applies no sales tax to electricity, but it does charge a system benefits charge and a stranded-cost recovery charge. Both live on the delivery side of the bill and do not change when you switch supplier.
Closest states by price
These jurisdictions charge within a fraction of a cent of New Hampshire, which is useful if you are comparing a move or a multi-state operating cost.

New Hampshire ranks #9 of 51 on price but 11th on the actual bill, because households there use about 643 kWh a month against a national average of 871. Climate and heating fuel drive most of that difference.
