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 Dam of the lift will be 21 minutes. It says that the expected dimensions of the passenger vessels the ship lift's basin was designed to carry will be X X . The moving mass (including counterweights) is 34,000 tonnes. The trials of elevator finished in July 2016, the first cargo ship was lifted in July 15, the lift time comprised 8 minutes. "Shanghai Daily" reported that the first operational use of the lift was on September 18, 2016, when limited ""operational testing"" of the lift began. Plans also exist for the construction of short portage railways bypassing the dam area altogether.
