Shepaug Generating Station

Shepaug is Connecticut’s largest hydroelectric generation station and is also the second largest source of carbon-free electricity in the state, located on the Housatonic River in both Newtown and Southbury. Lake Lillinonah, the impoundment created by the dam, is one of Connecticut’s largest lakes and serves as a significant economic driver for our host communities in western Connecticut. It provides fantastic recreational opportunities throughout the year and also contributes to the creation of a unique habitat for wildlife, notably dozens of bald eagles during the winter months.
