Pumped-storage power plants store electricity using water from dams. The new model for using the plants in combination with renewable energy has led to a revival of the technology. In 2000, there were around 30 pumped storage power plants with a capacity of more than 1,000 megawatts worldwide.
The stored energy is proportional to the volume of water and the height from which it falls. Pumped-storage power plants were first developed in the 1970s to improve the way major thermal and nuclear power plants dealt with widely fluctuating demand for electricity at different times of the day.
PSH facilities store and generate electricity by moving water between two reservoirs at different elevations. Vital to grid reliability, today, the U.S. pumped storage hydropower fleet includes about 22 gigawatts of electricity-generating capacity and 550 gigawatt-hours of energy storage with facilities in every region of the country.
The two reservoirs, an upper and a lower, together form a pumped-storage power system. Pumped-storage power plants are structured around two bodies of water, an upper and a lower reservoir 1 (see the diagram below).
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.

Hydroelectric Power Plant Working Principle. At the plant level, water flows through a pipe—also known as a penstock—and then spins the blades in a turbine, which, in turn, spins a generator that ultimately produces electricity. Most conventional hydroelectric facilities operate this way, including run-of-the-river systems and pumped ...
