Built in the 1970s, Raccoon Mountain is a pumped-storage hydropower facility (a “water-battery”) located in the United States along the Tennessee River. When energy demand is low, excess power from the regional electric utility’s nuclear plants is used to pump water (from a lower reservoir filled from the Tennessee River) up a shaft to the summit lake, where the water is stored as gravitational potential energy. When energy demand peaks, the water drains down from the summit lake, spinning turbines and generating upward of 1,700 megawatts of power—enough to power one million homes for twenty hours.
