The Jiangxia Tidal Power Plant located in Wuyantou, Wenling City, Zhejiang Province, China. It is the third largest tidal power station in the world. Although the proposed design for the facility was 3,000 KW, the current installed capacity is 3,200 KW, generated from one unit of 500 KW, one unit of 600 KW, and three units of 700 KW, totalling the installed capacity to 3,200 KW. Proposals were made to install a sixth 700 KW unit, but this has not yet been installed.[2][3] The facility generates up to 6.5 GWh of power annually.

The Jiangxia Tidal Power Plant feeds the energy demand of small villages at a 20 km (12 mi) distance, through a 35-kV transmission line. The maximum tidal range in the estuary is 8.39 m (27.5 ft).
