Three Gorges Dam calculated based on the average flow rate at the dam site, assuming the water level is 175 m and the plant gross efficiency is 90.15%. The actual power output in 2008 was obtained based on the monthly electricity sent to the grid. The Three Gorges Dam reached its design-maximum reservoir water level of for the first time on October 26, 2010, in which the intended annual power-generation capacity of 84.7 TWh was realized. In 2012, the dam's 32 generating units generated a record 98.1 TWh of electricity, which accounts for 14% of China's total hydro generation. The State Grid Corporation
Three Gorges of Hubei Province (), in the middle of Xiling Gorge. On May 20, 2006, the reservoir dam was completed, and the water level quickly reached the initial level of above the downstream river. The project was completed by the end of 2008, with a ship lift completed in 2015. The dam and Three Gorges Reservoir has had a massive impact on the region's ecology and people, involving the mass relocation of towns and villages. The higher water level has changed the scenery of the Three Gorges so that the river is wider and the mountains appear lower. However, the mountains
