The Tianshengqiao-II Dam (locally abbreviated as TSQ-II) is a dam and hydroelectric power station on the Nanpan River in the Anlong and Longlin districts in China. Construction of the dam and power plant began in 1982 and was complete in 1997.
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]
