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.
Penstock is used to connect the two reservoirs. The key components of a pumped storage power station are the hydro turbine and pump, which usually adopt the form of bladed hydraulic machinery. The mechanical energy of the water and the mechanical energy of the runner can be converted to each other.
Pumped storage power plants are currently the most economical way of efficiently storing large amounts of energy over a longer period. As the leading technology for energy storage services, pumped storage not only balances variable power production, but with its firm capacity it also serves as a reliable back-up.
