Pumped storage hydroelectricity is a form of energy storage using the gravitational potential energy of water. Storing the energy is achieved by pumping water from a reservoir at a lower elevation to a reservoir at a higher elevation.
The pumped hydro energy storage system (PHS) is based on pumping water from one reservoir to another at a higher elevation, often during off-peak and other low electricity demand periods. When electricity is needed, water is released from the upper reservoir through a hydroelectric turbine and collected in the lower reservoir .
Pumped storage is by far the largest-capacity form of grid energy storage available, and, as of 2020, accounts for around 95% of all active storage installations worldwide, with a total installed throughput capacity of over 181 GW and a total installed storage capacity of over 1.6 TWh.
Omid Palizban, Kimmo Kauhaniemi, in Journal of Energy Storage, 2016 Electrical energy may be stored through pumped-storage hydroelectricity, in which large amounts of water are pumped to an upper level, to be reconverted to electrical energy using a generator and turbine when there is a shortage of electricity.
Pumped storage facilities are built to push water from a lower reservoir uphill to an elevated reservoir during times of surplus electricity. In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation, which is why it is sometimes called a “water battery”.
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).
