The Three Gorges Dam represents the accumulated knowledge and know-how from all previous worldwide advances in dam technology including finding solutions for a wide-range of side effects apart from the main goal of generating power. It is the world’s largest power station in terms of installed capacity (22,500 MW), a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in Yiling District, Yichang, Hubei province, China. It has several innovations and integrated solutions. Except for a ship lift, the dam project was completed and fully functional as of July 4, 2012, when the last of the main turbines in the underground plant began production. The dam has 32 main turbines, each with a capacity of 700 MW, and two other smaller generators (50 MW each), with total electric generating capacity of the dam is 22,500 MW. The dam is intended, also, to increase the Yangtze River’s shipping capacity and reduce the potential for floods downstream by providing flood storage space. A partial solution for problems associated with the transport of nutrients because of silting behind the dam is, also, taken in consideration. Chinese government regards the project as a historic engineering, social and economic success, with the design of state-of-the-art large turbines, and a move toward limiting greenhouse gas emissions.
