Largest Hydro-Electric Power Plants

The list of the largest hydroelectric power stations, only plants with capacity larger than 2,000 MW are listed.

The Three Gorges Dam complex in Hubei, China, has the world's largest generating capacity although Itaipu power plant generates the most electricity in the world in a single Dam. It includes 2 generating stations. They are the Three Gorges Dam (22,500 MW when completed) and Gezhouba Dam (3,115 MW). As of 2009, the total generating capacity of this complex is 21,515 MW. The whole project is planned to be completed in 2012, when the total generating capacity will be 25,615 MW. In 2008, this complex generated 97.9 TWh of electricity (80.8 TWh from the Three Gorges Dam and 17.1 TWh from the Gezhouba Dam).

The Itaipu power plant on the Brazil-Paraguay border currently produces first most hydroelectricity power in the world in a single dam. With 20 generator units and 14,000 MW of installed capacity, in 2008 the Itaipu power plant reached a new historic record for electricity production by generating 94.68 terawatt-hours (340,800 TJ). It's important to remember that although a power plant could have a really large generating capacity (generators) it also needs to have a continuous flow of water throughout the year, like the Itaipu Dam.

The Jinsha River (the upper stream of Yangtze River) complex is the largest hydroelectric generating system currently under construction. It has 3 phases. Phase one includes 4 dams on the downstream of the Jinsha River. They are Wudongde Dam, Baihetan Dam, Xiluodu Dam, and Xiangjiaba Dam, with generating capacity of 7,400 MW, 14,000 MW, 12,600 MW, and 6,000 MW respectively. The total generating capacity of those four dams is 40,000 MW. Construction of Xiluodu Dam started on December 26, 2005. Construction of Xiangjiaba Dam started on November 26, 2006. Phase one is planned to be completed in 2015. Phase two includes 8 dams on the middle stream of the Jinsha River. The total generating capacity is 21,150 MW. Phase three includes 8 dams on the upper stream of the Jinsha River. The total generating capacity is 8,980 MW. The total combined capacity of the Jinsha complex with the Three Gorges complex will be 95,745 MW.
