A review of pumped hydro energy storage

A run-of-river hydroelectric power station that is downstream of a large dam takes advantage of storage in that dam to reduce dependence on day-to-day rainfall. Figure 14 shows the indicative capital cost of 1 GW off-river pumped hydro storage systems . The importance of large head (500 m and above), large slope and large W/R ratio is

Pumped Storage Hydropower | Department of Energy

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).
