Rocky River Pumped Hydro Storage Station
Completed in 1929, Rocky River was the very first pumped hydro storage station in the United States. Located along the Housatonic River in New Milford, Rocky River is Connecticut’s largest energy storage facility. Candlewood Lake, Connecticut’s largest lake, was created specifically to store the water that is used to generate electricity during times when it’s needed most, like hot summer days or during the polar vortex of 2018.
