Taum Sauk Hydroelectric Power Station

Hydroelectric power stations are typically located near water sources, or on the source itself, such as dams on rivers. But Taum Sauk Hydroelectric Power Station is located more than 80 kilometers from the nearest water source – the Mississippi river. Built on top of the mountainous St. Francois region of the Missouri Ozarks, approximately 140 km south of St. Louis near Lesterville, Missouri, the Taum Sauk Hydroelectric Power Station is a pure pumped-storage hydroelectric plant, designed to help meet peak power demands during the day. During periods of high electrical demand, water stored in a kidney-shaped reservoir on top of Proffit Mountain is released through turbines into a lower reservoir, two kilometers away, on the East Fork of the Black River. At night, when electrical demand is low, the excess electricity available on the power grid is used to pump water back to the mountaintop. In essence, the power plant functions like a huge battery,
