Xiaonanhai Dam Xiaonanhai Dam The Xiaonanhai Dam was a proposed dam on the Yangtze River in Chongqing, China. It was to have an associated 1,760 MW hydroelectric power station. Preliminary construction on the dam began on 29 March 2012 and earliest completion was expected in 2019. However, it was cancelled in March 2015 due to environmental concerns. The project, under responsibility of the Chongqing municipal government, was initiated under the stewardship of Bo Xilai prior to his fall from grace in 2012. The dam was to be constructed by China Three Gorges Corporation 40 km upstream of the city, and 700 km
Three Gorges Dam tonnes each and are designed to produce more than 700 MW of power. The designed head of the generator is . The flow rate varies between depending on the head available. The greater the head, the less water needed to reach full power. Three Gorges uses Francis turbines. Turbine diameter is 9.7/10.4 m (VGS design/Alstom's design) and rotation speed is 75 revolutions per minute. This means that in order to generate power at 50Hz, the generator rotors have 80 poles. Rated power is 778 MVA, with a maximum of 840 MVA and a power factor of 0.9. The generator produces
