Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing.

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).
If one-tenth of the global conventional hydropower capacity 5 is technically eligible for similar-scale pumped storage renovations, this could result in an increase of over 120 GW in storage capacity — 1.2 times greater than the total capacity of all other energy storage technologies worldwide.
