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).

PUMPED STORAGE HYDROELECTRIC SCHEMES AND

In water scarce areas, pumped storage schemes are used as an alternative to conventional hydroelectric power stations to provide the power needed during peak periods. Instead of the water being discharged, it is retained in the system and re-used. A pumped storage scheme consists of lower and upper reservoirs with a power station/pumping plant
