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
What is pumped hydro and how does it work?
Pumped hydro, the simple concept of using excess energy to pump water up a hill and hold it there until it''s needed, has been around for a long time. It already accounts for 97 percent of energy storage worldwide and is the technology that has led to the Federal Government''s enthusiasm for a "Snowy 2.0" scheme.
