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 ...
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 ...
Northfield Mountain is a pumped-storage hydroelectric plant and reservoir located on and under the similarly named Northfield Mountain in Erving and Northfield, Massachusetts It is currently owned by FirstLight Power Resources [ 1 ] (formerly NE Energy), which purchased the facility from Northeast Utilities in 2006.
This category is for pumped-storage power stations. For a list of pumped-storage power plants, see: List of pumped-storage hydroelectric power stations. Articles here should also have a category for Hydroelectric power stations in the appropriate country.
Pumped storage plants function similarly to a storage battery; they absorb excess power generated by such plants in off-peak hours, such as nighttime, using it to pump water into a reservoir. Later, when demand exceeds the base load, the flow of water from the reservoir generates additional electrical power to meet peak load demands. Like all ...
Lake Mutt in 2006. The highest reservoir in the complex is Lake Mutt (Muttsee), situated at 2,474 m (8,117 ft) above sea level.It had an original storage capacity of 9,000,000 m 3 (7,300 acre⋅ft), and was later expanded to 25,000,000 m 3 (20,000 acre⋅ft) during the Linthal 2015 expansion, to hold extra capacity for the new pumped-storage power station.
The functionality of a seawater pressure storage power plant is based on usual pumped-hydro storage plants. A hollow concrete sphere with an integrated pump-turbine will be installed on the bottom of the sea. Compared to well known pumped-hydro storage plants, the sea that surrounds the sphere represents the upper water basin.
