  • About

    Eversource serves more than a half-million New Hampshire homes and businesses, and we’re continuing a rich heritage that goes back to the development of the Granite State’s first broad-based electric system. Eversource is leading the way in powering the possible—developing a more reliable system for all seasons, supporting clean energy opportunities to ensure a secure energy future for homes and businesses, and growing a portfolio of energy efficiency programs and incentives that are helping homeowners and businesses save on energy use and costs every day. We’re also serving the neighborhoods where we work and live through community grants and numerous employee volunteer events in every corner of New Hampshire.
