About What pumps are used to make pumped water storage

A pumped-storage hydroelectricity generally consists of two water reservoirs at different heights, connected with each other. At times of low electrical demand, excess generation capacity is used to pump water into.

In closed-loop systems, pure pumped-storage plants store water in an upper reservoir with no natural inflows, while pump-back plants utilize a combination of pumped storage.

Taking into account conversion losses and evaporation losses from the exposed water.

The main requirement for PSH is hilly country. The global greenfield pumped hydro atlas lists more than 600,000 potential sites around the world, which is about 100 times.

Water requirements for PSH are small: about 1 gigalitre of initial fill water per gigawatt-hour of storage. This water is recycled uphill and back downhill between the two reservoir.In periods of low demand, water is pumped up into the reservoir, generally using some sort of reversible turbine / pump such as a Francis turbine. In these low demand times, excess electricity from the grid is used to pump the water up.
