It is one of the cascade development in the Minjiang river basin. It is a powerhouse in river channel.The main structures of Shaxikou Hydropower Station is consist of overflow spillway dam, nonoverflow spillway dam, powerhouse and lock. The dams are concrete gravity dams. The overflow spillway dam lies in the centre of the riverbed. The powerhouse lies on the right, and the lock is located on the left. The top of the nonspillway dam is at an elevation of 93 meters. The upstream of the dam is vertical, the lower slope degree is 1:,and the upper slope degree is 1:. the crest of the weir is at an elevation of meters. The overflow spillway dam is about 340 meters long in total, with 18 openings each of 17 meters wide, discharging most of the flood flow along the main river channel.The normal water lever of the reservoir is meters,while the design flood water level of the reservoir reaches at meters. The checking flood water level is about 91 meters. And the dead water level is only meters.The design crosshead is meters. The project has a total installed capacity of 320MW. It houses four axialflow turbines coupled with generators 8MW each. The type of the turbine is ZZ560LH850.
