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. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

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.
In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over periods of years, months, weeks, days or hours, thereby controlling when and how much electricity is generated. This ability enables them to quickly respond to the increasing demand for flexible power in electrical grids 2, 3.
Storage hydroelectric is sometimes also known as ‘impounded power’. A natural loch or man-made reservoir formed by draining a river collects water from the surrounding area, which can be hundreds or even thousands of square kilometres in size. What is created is a store of water situated at a higher altitude than the power station it supplies.
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.
