Three Gorges Dam - Wikipedia, the free encyclopedia

The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in Yiling District, Yichang, Hubei province, China. The Three Gorges Dam is the world's largest power station in terms of installed capacity (22,500 MW). In the year of 2012, the amount of electricity the dam generated is neck to neck with the Itaipu Dam. [3][4]

Except for a ship lift, the dam project was completed and fully functional as of July 4, 2012,[5][6] when the last of the main turbines in the underground plant began production. Each main turbine has a capacity of 700 MW.[4][7] The dam body was completed in 2006. Coupling the dam's 32 main turbines with two smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam is 22,500 MW.[4][8][9]

As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity and reduce the potential for floods downstream by providing flood storage space. The Chinese government regards the project as a historic engineering, social and economic success,[10] with the design of state-of-the-art large turbines,[11] and a move toward limiting greenhouse gas emissions.[12] However, the dam flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides.[13] The dam has been a controversial topic both domestically and abroad.[14]
