Generators of an underground power station of the Three Gorges project have started installation, and the first underground turbine is expected to be put to use in 2010.
China Gezhouba (Group) Corporation, which had been a major participant in the Three Gorges project construction, said on its website it would be responsible for installing and fine-tuning the underground turbines in the station.
All six underground turbines were scheduled to be ready by 2012,with a total capacity of 4.2 million kw, the state-owned China Three Gorges Project Corporation said in a statement.
Launched in 1993, the hydroelectric project is built near Yichang in central China's Hubei Province to tame the unruly Yangtze River and fuel China's economic development with clean and cheap energy.
The project mainly includes a 185-meter-high dam, a five-tier ship lock and 32 generators, 26 of which are on the river banks and all had gone into operation by October last year, with installed capacity totaling 18.2 million kw.
As of April 7, the world's largest hydroelectric project had generated 300 billion kwh of electricity since its first generator was put into operation in July 2003. The amount is equivalent to 8.8 percent of the national consumption last year.
