In a pumped hydro storage system, electrical energy is stored in the form of potential energy from water stored in a high-level reservoir that is pumped from a low-level reservoir. The water pumps used to raise the water level (from the lower-level to higher-level reservoir) use electrical power during off-peak hours, which can be considered the charging process.

The existing 161,000 megawatts (MW) of pumped storage capacity supports power grid stability, reducing overall system costs and sector emissions. A bottom up analysis of energy stored in the world''s pumped storage reservoirs using IHA''s stations database estimates total storage to be up to 9,000 gigawatt hours (GWh).
With higher needs for storage and grid support services, pumped hydro storage is the natural large-scale energy storage solution. It provides all electricity delivery-related services from reactive power support to
Abstract. Pumped hydroelectric storage is currently the only commercially proven large-scale (>100 MW) energy storage technology with over 200 plants installed worldwide with a total installed capacity of over 100 GW. The fundamental principle of pumped hydroelectric storage is to store electric energy in the form of hydraulic
Among all ESS technologies, pumped hydro storage (PHS) is the most mature storage technology.
