The dam's reservoir is fed by the tailwaters of the Tianshengqiao-I Dam 7 km (4 mi) upstream. The dam diverts water east into three 9.53 km (6 mi) long and 9 m (30 ft) diameter headrace tunnels towards the actual power station 24°56′47″N 105°15′07″E / 24.94639°N 105.25194°E. At the power station, the water powers six 220 megawatts (300,000 hp) Francis turbines for the production of 1,320 MW (1,770,000 hp) of electricity.[1]
