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 ...
Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, [1] which is more than all other renewable sources combined and also more than nuclear power. [2] Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2]
This is a list of operational hydroelectric power stations in the United States with a current nameplate capacity of at least 100 MW. 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 ...
The hydropower generators could “replace diesel-powered generators used for plant startup,” according to Mesa, and could “provide a continuous flow of water to support or maintain minimum ...
Between 2003 and 2010, the turbines were upgraded so that each generator/motor operates at up to approximately 318 MVA at 0.9 power factor pumping power, or 286 megawatts (384,000 hp) as a generator. Additionally, the old 285 MVA generator step up transformers were replaced with new 17kV/345kV, 325 MVA transformers.
The largest hydroelectric power station is the Three Gorges Dam in China, rated at 22,500 MW in total installed capacity. After passing on 7 December 2007 the 14,000 MW mark of the Itaipu Dam , the facility was ranked as the largest power-generating facility ever built.
The following page lists hydroelectric power stations that generate power using the run-of-the-river method. This list includes most power stations that are larger than 100 MW in maximum net capacity, which are currently operational or under construction.
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]
