All construction work on the Three Gorges Project, the largest hydropower project in the world, is scheduled to be completed by 2015, said a spokesman with the developer, China Three Gorges Corp.
The remaining parts to be constructed are an underground power station with six hydropower turbo-generators being cut beneath the mountain on the southern bank of the Yangtze River and a lift for vessels on the river's northern bank.
The multi-functional water control system started construction 18 years ago. Its main work includes a gigantic dam, a five-tier ship lock.
In addition to hydropower generation, the project is also capable of flood control and navigation. The Three Gorges Project has had 26 hydropower turbo-generators in operation.
Upon completion, the project is able to generate 100 terawatts hours electricity a year. By the end of 2010, the project had generated more than 440 TWh of electricity since it started generating power in 2003.
