Public Service of New Hampshire (PSNH) is the Granite State's largest electric utility, serving about 500,000 homes and businesses throughout the state. Our personnel include almost 1,500 employees who work and live in New Hampshire, contributing in many ways to the communities where they reside.
Formed in 1926, PSNH has grown to comprise three fossil fuel-fired generating plants, one wood-burning power plant, and nine hydroelectric facilities, jointly capable of generating more than 1,110 megawatts of electricity. Through its own power plants and through power purchase arrangements with other suppliers, approximately 21 percent of the energy PSNH supplies to customers comes from renewable sources. This is one of the highest percentages of any major utility in New England.
As a wholly-owned subsidiary of Northeast Utilities, a utility holding company based in Connecticut. PSNH is an integral part of New England's largest electric system. This ample and diverse supply of energy provides the foundation for continued economic growth and prosperity in New Hampshire.
