Pumped Storage Hydropower | Department of Energy
What is Pumped Storage Hydropower? Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into ...
