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 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.
Pumped storage is the most widespread energy storage system in use on power networks. Its main applications are for energy management, frequency control, and provision of reserve. PHS is a mature technology with large volume, long storage period, high efficiency, and relatively low capital cost per unit of energy.
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 Hydro Energy Storage (PHES) systems exploit difference in energy potential between two different heights to storage energy. PHES systems are operated by pumping and swirling the water between two dams. Water is pumped using off-peak electricity and discharged in peak hours.
