Profile Overview

Quick Facts

  • About three-fifths (59%) of New Hampshire households use petroleum products as their primary heating fuel, the second-largest share among the states and almost seven times greater than the national average.
  • Seabrook, one of only two nuclear power plants in New England and the largest power plant in New Hampshire, provided 58% of New Hampshire’s 2022 total in-state electricity net generation.
  • In 2022, 14% of New Hampshire's electricity generation came from renewable resources, including small-scale solar installations. Most of the state's renewable generation comes from biomass. hydroelectric power, and wind.
  • New Hampshire has the two remaining coal-fired power plants in New England—Schiller at Portsmouth and Merrimack at Bow. Coal-fired plants no longer supply baseload power, but they play an important role in providing electricity on high demand days.
  • New Hampshire's residential sector accounted for about one-third of state energy consumption in 2021, even though about 1 in 10 New Hampshire homes are only seasonally or occasionally occupied.
