This is a list of electricity-generating power stations in the U.S. state of New Hampshire, sorted by type and name. In 2024, New Hampshire had a total summer capacity of 4.5 GW through all of its power plants, and a net generation of 16,942 GWh. In 2025, the electrical energy generation mix was 56.4% nuclear, 27.5% natural gas, 7% hydroelectric, 4.1% biomass, 2.5% wind, 1.2% coal, 0.9% petroleum, and 0.3% other. Smaller-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 408 GWh to New Hampshire's electrical grid in 2025.

During 2019, New Hampshire had two of the three coal power plants, and one of two nuclear power plants operating in New England. More electricity was generated than was consumed in-state. Renewables sources generated 17% of all electrical energy from New Hampshire. Wind generated more electricity than coal for the first time in 2016, while the state did not yet host a utility-scale (larger than 1 MW) solar power plant as of 2019.
