Construction of China's Three Gorges Dam Formally Begins
- Wikipedia records that construction of the dam at Sandouping in Yiling District, Yichang, Hubei started on 14 December 1994; the Travel China Guide schedule lists that date as the grand commencement ceremony of the project[1]
- The project had been officially approved in 1992; the Yangtze was dammed in November 1997, the main left-bank power units began construction in April 1995, and the schedule splits the build into three stages ending in 2009
- It was expected to be fully operational in 2009, but extra work such as the underground power plant with six more generators delayed full operation to 2012; Wikipedia lists a final installed capacity of 22,500 MW and a cost of 203 billion yuan (US$31.765 billion)[1]
- By May 2006 about 27 million cubic metres of concrete had gone into the structure, Nature reported, more than eight times the Hoover Dam, and more than a million people had been relocated for the reservoir[3]
- POWER magazine described the finished plant as the world's largest by capacity, with 34 generators totalling 22.5 GW after the last main generator finished testing on 23 May 2012[2]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
