Great River Hydro's diverse facilities have contributed significantly to New England's power grid for over a century. Our sustainable hydropower systems in New Hampshire, Vermont, and Massachusetts have continued to safely and reliably generate electricity at times when our region's consumers and industries need it the most. Great River Hydro and its dedicated and experienced community-based employees will continue to lead in the 21st century as the world demands more carbon-conscious energy sources. Sustainability The renewable power generated by Great River Hydro facilities can power over 213,000 homes each year, but the story doesn’t end there. Unlike solar, wind, and run-of-river hydro, Great River Hydro’s renewable power is on-demand. And unlike batteries, pumped storage hydro, and other storage resources, our reservoirs store energy without consuming electricity from the grid. Carbon-free, dispatchable power is critical to achieving a reliable and sustainable power grid in the 21st century. Learn More Clean Hydropower from Great River Hydro displaces 680,000 tons of carbon dioxide annually. 11 out of our 13 generating facilities are certified by the Low Impact Hydropower Institute, sustainably embracing the power of flowing water. Reliable Great River Hydro’s large reservoirs and sequential generating stations allow us to store vast quantities of energy and efficiently dispatch it into the grid when it is needed the most – not just when the sun is shining or when the wind is blowing. Our fast-start, on-demand capability provides carbon-free reliability to our region’s electricity supply as more variable solar and wind generation enter our region’s energy mix.
