New Hampshire Electricity Prices

New Hampshire residential electricity costs 27.33¢/kWh as of May 2026, the ninth most expensive rate among the 50 states and DC. This is 8.89¢/kWh above the national average of 18.44¢/kWh, a premium of 48.2%. Neighboring Massachusetts and Maine both charge more, at 28.82¢/kWh and 28.63¢/kWh respectively, while Vermont is less expensive at 24.89¢/kWh.

Over five years the residential rate has climbed 37%, from 19.95¢/kWh in May 2021. The two-decade trajectory is steeper still: since May 2006 it has risen 72.1%, from 15.88¢/kWh. Over the full span since records began in January 2001, the increase totals 102.1%, from 13.52¢/kWh. The state's record high of 32.26¢/kWh came in September 2022; the lowest recorded was 11.26¢/kWh in September 2001. Commercial and industrial rates stand at 20.59¢/kWh and 17.04¢/kWh.

The typical residential bill is $167 per month against a national average of $155, despite consumption of just 643 kWh compared with the national 871 kWh. The high rate substantially outweighs the below-average usage, leaving households paying more for less power. The 13.8% year-over-year increase in the residential rate continues a rapid climb.
