The Hoover Dam in Arizona and Nevada was the first hydroelectric power station in the United States to have a capacity of at least 1,000 MW upon completion in 1936. Since then numerous other hydroelectric power stations have surpassed the 1,000 MW threshold, most often through the expansion of existing hydroelectric facilities.
Mactaquac Dam with the spillways open, April 2017. The Mactaquac Dam is an embankment dam used to generate hydroelectricity in Mactaquac, New Brunswick.It dams the waters of the Saint John River and is operated by NB Power with a capacity to generate 670 megawatts of electricity from 6 turbines; this represents 20 percent of New Brunswick's power demand.
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 .
The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
This article provides a list of the largest hydroelectric power stations by generating capacity. Only plants with capacity larger than 3,000 MW are listed. The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power. In second place is the Baihetan Dam, also in China, with a capacity of ...
The Andekaleka Dam is a gravity dam on the Vohitra river near Andekaleka in eastern Madagascar.The primary purpose of the dam is hydroelectric power generation and it diverts water from the Vohitra east into a 4 kilometres (2.5 mi) headrace tunnel where it reaches a 91 megawatts (122,000 hp) underground power station.
