Power Stations

According to the scheme, two power plants will be placed at the toe of the dam, one on each side. The total length of the power plant on the left is about 643.6 m, with 14 sets of turbine generator units installed, while that of the one on the right , 584.2 m in total length, 12 turbine generator units installed. Thus, there are 26 sets of turbine generator units in total (the turbine is of Francis type) , 700 MW for each, totaling 18,200 MW in installed capacity that will produce 84.68 TW/h of electricity output annually. 500 kV AC transmission lines will send electricity to Central China and the east of Sichuan Province. 600 kV DC transmission lines will send the electricity to East China. There are 15 transmission lines in total.

On the right bank, enough room has been preserved for the future underground power plant with 6 turbine generator units, 4,200 MW of installed capacity. The intakes will be constructed simultaneously with the project.
