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.
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.
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 Santo Antônio Dam is designed as a run-of-the-river hydroelectric dam, power plant, and factory. The dam itself is 13.9 m (46 ft) tall and 3,100 m (10,171 ft) long, creating a reservoir with a surface area of 271 km 2 (105 sq mi), of which 164 km 2 (63 sq mi) is the previously existing river channel.
This dam slows a normally fast and shallow river for partial diversion to a hydroelectric dam. The diversion tunnel opening can be seen in the upper left. The Imperial Dam diverting the Colorado River in the southwestern United States. A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural
By 1979 BC Hydro was concerned about the safety of dams built before 1961. A series of earthquakes since then had shown the susceptibility of some dams to liquefaction. [3] A review begun in 1984 discovered the dam was built on loose, saturate sands and silts. The dam was reinforced using injected grout while under full pool. [4]

Irrigation dams with a length and height of more than 100 m (330 ft) and 10 m (33 ft) are listed, including all the state-run hydroelectric power stations.
