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

Pumped storage: powering a sustainable future
Pumped storage provides a ''load'' when the wind is blowing and the sun is shining, and it also provides a reliable and immediate source of dispatchable energy when the available renewable generation can''t meet demand. By pumping the water uphill when generation exceeds demand, the pumped storage scheme is essentially ''storing'' energy
