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 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.
Moreover, run-of-the-river hydroelectric plants do not have reservoirs, thus eliminating the methane and carbon dioxide emissions caused by the decomposition of organic matter in the reservoir of a conventional hydroelectric dam. [12] That is a particular advantage in tropical countries, where methane generation can be a problem.
The Kajaki Dam is "an earth and rockfill embankment type dam" [4] located on the Helmand River in the Kajaki District of Helmand Province in Afghanistan, about 161 km (100 mi) northwest of Kandahar. It has a hydroelectric power station , which is operated by the Helmand and Arghandab Valley Authority through the Ministry of Energy and Water .
Boundary Dam is a concrete arch gravity-type hydroelectric dam, finished in 1967, on the Pend Oreille River, in the U.S. state of Washington. The dam is located in the northeast corner of Washington state. It is operated by Seattle City Light [4] and makes up a significant portion of the City of Seattle's energy portfolio. On average, it ...
The removal of the four hydroelectric dams — Iron Gate Dam, Copco Dams 1 and 2, and JC Boyle Dam — allows the region’s iconic salmon population to swim freely along the Klamath River and its ...
The Safe Harbor Dam (also Safe Harbor Hydroelectric Station) is a concrete gravity dam, with an associated hydroelectric power station, on the lower Susquehanna River.It is the most northerly and last of three Great Depression-era public electrification projects' hydroelectric dams, and was constructed between April 1, 1930, and December 7, 1931.
