Quick Summary

The Daguangba hydropower station is located on the middle reach of the Changhua River in Hainan, China. Completed in 1995, it is a significant source of hydroelectric power for the island. While Hainan has substantial mineral and natural gas reserves, and is a major producer of salt, its power generation capacity, including hydroelectric output, has historically struggled to meet demand, particularly due to the seasonal nature of its rivers. Efforts have been made to diversify energy sources and improve supply, including a submarine power-transmission cable connecting Hainan to mainland China's electricity grid.1
