Pumped hydroelectric energy storage stores energy in the form of potential energy of water that is pumped from a lower reservoir to a higher level reservoir. In this type of system, low cost electric power (electricity in off-peak time) is used to run the pumps to raise the water from the lower reservoir to the upper one.

A dynamic energy storage solution, pumped storage hydro has helped 'balance' the electricity grid for more than five decades to match our fluctuating demand for energy. Pumped storage hydro (PSH) involves two reservoirs at different elevations.
Pumped storage hydro (PSH) must have a central role within the future net zero grid. No single technology on its own can deliver everything we need from energy storage, but no other mature technology can fulfil the role that pumped storage needs to play.
Potential for Expansion: With the total installed capacity of pumped storage hydropower at 158 GW in 2019 and an expected increase to 240 GW by 2030, countries like Japan and Norway are exploring significant potential for expanding their storage capacities.
