FirstLight Power Resources

FirstLight Power Resources, a subsidiary of GDF SUEZ Energy North America, operates a portfolio of power generation plants in Connecticut and Massachusetts that are primarily pumped hydro storage and traditional hydroelectric facilities. GDF SUEZ's first solar operation in North America is also among FirstLight's assets in Western Massachusetts.

FirstLight’s hydro and pumped hydro storage plants constitute the largest fuel sector of North America’s renewables fleet. With the ability to achieve full generation output from a shut down condition in 10 minutes, its premier asset—Northfield Mountain—is the largest, most flexible pumped hydro storage facility in New England and among the largest in the United States.
