Pumped-storage Hydroelectric
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. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Castaic Power Plant
Castaic Power Plant, also known as the Castaic Pumped-Storage Plant, is a seven unit pumped-storage hydroelectric plant, operated by the Los Angeles Department of Water and Power, which provides peak load power from the falling water on the West Branch of the California State Aqueduct. It is a cooperative venture between the LADWP and the Department of Water Resources of the State of California. An agreement between the two organizations was signed on September 2, 1966, for construction of the project. Location The Castaic Power Plant is located about from the northern Los Angeles city limits at the upper end of the West arm of Castaic Lake. Water supply California State Aqueduct water en route to Southern California is pumped up through the Tehachapi Mountains (by the Edmonston Pumping Plant) to the Tehachapi Afterbay. There the aqueduct divides into East and West Branches. The West Branch water is again pumped at the Oso Pumping Plant to Quail Lake, near Highway 138 Eas ...

Okukiyotsu Pumped Storage Power Station
The No. 1 and No. 2 are two large pumped-storage hydroelectric power plants in Yuzawa, Minamiuonuma, Niigata Prefecture, Japan. With a combined installed capacity of , the system is the third largest pumped-storage power station in Japan. The facilities are run by Electric Power Development Company (J-Power). Like most pumped-storage facilities, the power station uses two reservoirs, releasing and pumping as the demand rises and falls. Tashiro lake, formed by the Kassa Dam, is the upper artificial reservoir, while Futai Dam on the Kiyotsu river forms the lower reservoir. Both dams are rockfill type dams, with a height of 90 m and 87 m, respectively. The reservoirs were built between 1972 and 1978. Okukiyotsu No. 1 is the first plant to be built on the site, and employs four 260 MW pump/generator units, for a total net capacity of 1000 MW. The maximum water flow is 260 cubic meters per second.

Mingtan Pumped Storage Hydro Power Plant
The Mingtan Dam () is a dam that spans the Shuili River about downstream from the outlet of Sun Moon Lake in central Taiwan with a height of about . It forms Mingtan Reservoir which is the lower reservoir for the Mingtan Pumped Storage Hydro Power Plant. History To meet the demand of the ever-increasing peak load in Taiwan and to fully utilize off-peak power, the Taiwan Power Company (Taipower) had entrusted European consultants to undertake feasibility study since 1973. The study showed the feasibility of constructing Mingtan Dam to meet such peak load demand, to avoid expanding current fossil-fuel power plants in Taiwan and to have lower operational cost. The dam was completed in 1994 and opened a year later. During the 7.7-magnitude 1999 Jiji earthquake, Mingtan was one of eight dams that sustained damage, but did not collapse.

Raccoon Mountain Pumped-Storage Plant
Raccoon Mountain Pumped-Storage Plant is a pumped-storage hydroelectric underground power station in Marion County, just west of Chattanooga in the U.S. state of Tennessee. The facility is owned and operated by the Tennessee Valley Authority (TVA). Construction was started in 1970 and was completed in 1978. Water is pumped from Nickajack Lake on the Tennessee River at the base of Raccoon Mountain to a storage reservoir built at the top of the mountain. The reservoir at the top of the mountain covers , with a dam that is high and long, the largest rock-fill dam ever built by TVA. It takes 28 hours to fill the upper reservoir. During periods of high electric demand, water can be released from the reservoir through a tunnel A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube cons ... drille ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinorwig Power Station
The Dinorwig Power Station (; ), known locally as Electric Mountain, or Mynydd Gwefru, is a pumped-storage hydroelectric scheme, near Dinorwig, Llanberis in Snowdonia national park in Gwynedd, north Wales. The scheme can supply a maximum power of and has a storage capacity of around . Purpose The scheme was built at a time when responsibility for electricity generation in England and Wales was in the hands of the government's Central Electricity Generating Board (CEGB); with the purpose of providing peak capacity, very rapid response, energy storage and frequency control. Dinorwig's very rapid response capability significantly reduced the need to hold spinning reserve on part loaded thermal plant. When the plant was conceived the CEGB used low efficiency old coal and oil fired capacity to meet peaks in demand. More efficient 500 MW thermal sets were introduced in the 1960s, initially for baseload operation only. Dinorwig could store cheap energy produced at night by low ...

Ludington Pumped Storage Power Plant
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 world. Characteristics It consists of a reservoir deep, long, and wide which holds or 82859 acre-feet of water. The reservoir is located on the banks of Lake Michigan. Because impervious bedrock is more than below the reservoir, the builders had to line the reservoir with a layer of asphalt and clay to prevent water seeping into the ground.
