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 ...
In 2021, Alabama had a total summer capacity of 28,911 MW through all of its power plants, and a net generation of 144,967 GWh. [2] The electrical energy generation mix in 2023 was 43.7% natural gas, 32.5% nuclear, 13.7% coal, 7.1% hydroelectric, 2.2% biomass, and 0.8% solar. [ 1 ]
Alabama Power is an investor-owned, tax-paying utility, and the second largest subsidiary of Southern Company. More than 84,000 miles (135,000 km) of power lines carry electricity to customers throughout a service territory of 44,500 square miles (115,000 km 2 ).
The earthen dam was constructed in 1967 by the Alabama Power Company, with a height of 170 feet (52 m), and a length of 11,178 feet (3,407 m) at its crest. [1] It impounds the Coosa River for 225 MW of hydroelectric power, the last and largest of Alabama Power's string of seven hydropower facilities on that river.
All three of these are nuclear power plants, and eight of the top 10 power plants with the largest annual net generation in 2021 are nuclear power plants. [2] The largest power generating facility under construction is the Chokecherry and Sierra Madre Wind Energy Project in Wyoming, which will generate 2,500-3,000 MW when completed in 2026. [3]
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.
The lake was created by Alabama Power with the construction of the Lewis Smith Dam. One of the largest earthen dams in the eastern United States , it stretches 2,200 feet (670 m) in length and reaches a maximum height of 300 feet (91 m).
As of 2021, the largest power generating facility ever built is the Three Gorges Dam in China. The facility generates power by utilizing 32 Francis turbines each having a capacity of 700 MW and two 50 MW turbines, [ 1 ] totalling the installed capacity to 22,500 MW , more than twice the installed capacity of the largest nuclear power station ...
