2.4 Power Stations According to the scheme, two powerhouses will be placed at the toe of the dam, one on each side. In the left one, about 643.6 m long, 14 sets of turbine generator units will be installed, while in the right one, 584.2 m in total length, 12 turbine generator units will be installed. Thus, there are 26 sets of turbine generator units in total (the turbine is of a Francis type), 700 MW each, totaling 18,200 MW in installed capacity that will produce 84.68 TW¡¤h of electricity Output annually. There are 15 transmission lines, with 500 KV AC lines to Central China and east Sichuan Province and I 500 kV DC lines to East China. On the right bank, enough room has been preserved for the future underground powerhouse of 6 turbine generator units with 4, 200 MW of installed capacity. The intakes of these units will be constructed simultaneously with the project. ¡¡

¡¡ 2.5 Navigation Facilities The permanent navigation structures consist of a permanent shiplock and a shiplift. The shiplock is schemed as a double--way five--step flight locks, each lock chamber is dimensioned at 280¡Á34 /5 m (i.e., length ¡Á width ¡Áwater depth) capable of passing 10, 000 tons of barge fleet. The shiplift is designed as a one step vertical hoisting type with a container sized 120 ¡Á 18 ¡Á 3.5 m, capable of carrying one 3,000 ton passenger or cargo boat each time. In addition, one temporary shiplock is schemed for use during the construction period with an effective chamber size of 240¡Á24 ¡Á 4 m.
