6 FAQs about [Hydropower station energy storage station]

What is pumped storage hydropower (PSH)?

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 the upper reservoir (recharge).

What is a pumped hydroelectric storage facility?
