Northfield Mountain Pumped Hydro Storage Station

Northfield Mountain, FirstLight’s flagship facility, is New England’s largest energy storage facility. This giant water battery is capable of powering more than 1 million homes for up to 7.5 hours each and every day, making it an ideal solution to help other intermittent renewable resources like windpower decrease greenhouse gas emissions in the region. The “Mountain”, as it is known in the community, stores energy in an upper pond that is then released through the station when electricity is needed most. It provides fantastic recreational opportunities for visitors to take advantage of, including hiking, rock climbing, fishing, camping, snow shoeing, and other activities.
