Great River Hydro (GRH) is New England’s largest producer of conventional hydropower. Our facilities have been providing critical energy services to New England for over 100 years. We own and operate 13 hydroelectric generating stations on the Connecticut and Deerfield Rivers in New Hampshire, Vermont, and Massachusetts, with a total capacity of 589 megawatts, enough to power over 200,000 homes in the region.

Our most important asset is our people. The GRH team includes over 100 highly skilled professionals who manage, operate, and maintain our facilities. Safety is our highest priority. Our GRH team members are committed to the safety and well-being of each other, our communities, and our environment, every single day. Our safety culture drives our successful delivery of reliable, clean energy. “Renewable power from New England for New England” means much more than electricity alone. We work closely with environmental, energy, community, and regional stakeholders to achieve safe, responsible operation of our facilities.
