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.
The pumped storage hydroelectricity power station consists of two circular concrete silos, each of about 32 metres (105 ft) internal diameter. [2] Each of the silos houses a 285 megawatts (382,000 hp) turbine generator spinning at 120 rpm and pump set, giving a total capacity of 570 megawatts (760,000 hp).

At its completion, the Taum Sauk plant was by far the largest pumped storage plant in North America in a number of measures, and was considered a major milestone in the development of pumped storage technology. Its pump-turbines were the largest ever produced at the time of construction, it had an unusually high head (the highest in the US at ...
While less efficient than pumped hydro or battery storage, this type of system is expected to be cheap and can provide long-duration storage. [57] [58] A pumped-heat electricity storage system is a Carnot battery that uses a reversible heat pump to convert the electricity into heat. [59] It usually stores the energy in both a hot and cold ...
The following page lists all pumped-storage hydroelectric power stations that are larger than 1,000 MW in installed generating capacity, which are currently operational or under construction. Those power stations that are smaller than 1,000 MW , and those that are decommissioned or only at a planning/proposal stage may be found in regional ...

The Blenheim–Gilboa Pumped Storage Power Station is a pumped-storage hydroelectricity plant in the Catskill Mountains of New York State. The plant is part of the New York Power Authority, and can generate over 1,100 megawatts (1,500,000 hp) of electricity. It is used daily to cover peak demand.
