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 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 ...
Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...
The Ludington Pumped Storage Plant is a hydroelectric plant and reservoir in Ludington, Michigan. It was built between 1969 and 1973 at a cost of $315 million and is owned jointly by Consumers Energy and DTE Energy and operated by Consumers Energy. At the time of its construction, it was the largest pumped storage hydroelectric facility in the ...
The pumped-storage hydroelectric plant was constructed from 1960–1962 and was designed to help meet daytime peak electric power demand. [8] It began operation in 1963. Electrical generators are turned by water flowing from a reservoir on top of Proffit Mountain into a lower reservoir on the East Fork of the Black River .
The Bath County Pumped Storage Station is a pumped storage hydroelectric power plant with a maximum generation capacity of 3,003 MW, [3] an average of 2,772 MW, [4] and a total storage capacity of 24,000 MWh. [4]
Bath County Pumped Storage Station is the largest such facility in the world. Other stations of this type include Raccoon Mountain Pumped-Storage Plant, Bear Swamp Hydroelectric Power Station and Ludington Pumped Storage Power Plant on Lake Michigan, previously the largest in the world.
Kannagawa Hydropower Plant is a pumped-storage hydroelectric power plant near Minamiaiki in Nagano Prefecture and Ueno in Gunma Prefecture, Japan. The power house is 1,600 feet (490 m) underground and measures 708 ft (216 m) long, 108 feet (33 m) wide, and 169 feet (52 m) high.
