A conventional dammed-hydro facility (hydroelectric dam) is the most common type of hydroelectric power generation. Chief Joseph Dam near Bridgeport, Washington , is a major run-of-the-river station without a sizeable reservoir.
The Sidney A. Murray Jr. Hydroelectric Station, also known as Louisiana Hydroelectric (LA Hydro), opened in response to a need for a non-polluting, less-costly power source for Vidalia, Louisiana. A site approximately 40 miles south of the town was selected for the new facility. The 192 MW plant started full-scale operations in 1990. [1]
Hoover Dam's initial 1,345 MW power station was the world's largest hydroelectric power station in 1936; it was eclipsed by the 6,809 MW Grand Coulee Dam in 1942. [20] The Itaipu Dam opened in 1984 in South America as the largest, producing 14 GW , but was surpassed in 2008 by the Three Gorges Dam in China at 22.5 GW .
English: Hydroelectric dam. Water from the reservoir rushes through the penstock into the powerhouse. The water spins the turbine, which drives the generator. Inside the generator is a large electromagnet that spins within a coil of wire, producing electricity.
The Hatanagi Project was designed as a pumped-storage hydroelectricity facility, with the discharge from Hatanagi No.1 Dam discharging through a 5 kilometres (3.1 mi) penstock into a lake created by the smaller Hatanagi No.2 Dam downstream. The reversible turbine generators at the Hatanagi No.1 power plant were designed to function as either ...
The Colley Wobbles Power Station is a hydroelectric power facility located approximately 30 km east of Dutywa in the Amathole District Municipality of the Eastern Cape of South Africa. Water is drawn from behind a dam on the Mbhashe River and diverted through a penstock to the Colley Wobbles Power Station. The power station discharges into the ...
The Batang Ai Dam (Malay: Empangan Batang Ai) is a concrete-face rock-fill dam in Batang Ai National Park in Sarawak, Malaysia. The power station comprises four 25 MW turbines, totalling the installed capacity to 100 MW. The station is operated by Sarawak Electricity Supply Corporation. Preparations for the dam began in 1975, before the design ...
The dam emits more greenhouse gas than an oil-fuelled power plant with the same capacity would emit. In 1990 the reservoir emitted 11.6 times more greenhouse gases than an oil-burning plant would have given off making the same amount of energy. This has since declined to a stable level of 2.6 times higher than the fossil fuel alternative. [22]
