The Three Gorges Dam had been planned for nearly 100 years. As early as in 1918, Sun Yat-sen, the pioneer of China’s revolution in modern times, had put forward a proposal to build a dam on the Yangtze River. In 1992, the Three Gorges Dam construction was officially approved and the preparation work started soon later. In 1994, the construction work on site began, which mainly includes the dam, hydropower station and navigation structures. In 2006, the dam was completed. It was not until 2009 that the whole project was fully completed. The construction was marked by three stages.

Nov. 22nd, 2003
No.1 power generation set was connected to the grid and began to generate electricity.
Nearly-completed five-level ship locks on April 14, 2003 Aug. 18th, 2003
No. 3 power generation set was connected to the grid and began to generate electricity.
July 10th, 2003
No.2 power generation set was connected to the grid and put into production.
June 16th, 2003
The double-lane and five-step ship lock was completed to let ships pass.
