The Shapai Dam is an arch dam on the Caopo River in Sichuan Province, China. The dam is 130 metres (427 ft) tall and composed of roller-compacted concrete. There are no spillways on the face of the dam but two tunnels are utilized with a discharge capacity of 453 cubic metres per second (15,998 cu ft/s). A single penstock feeds water to a power station 5 kilometres (3 mi) downstream. The power station contains 2 x 18 MW generators with a combined capacity of 36 MW.[1]
