How does Hainan produce much of its electricity?

Hainan generates much of its electricity through hydroelectric power, with the Daguangba hydropower station on the Changhua River serving as a primary facility. The remainder of the island's power is largely supplied by thermal plants.1

Because the seasonal nature of local rivers can periodically limit hydroelectric output and industrial demand often exceeds supply, the province has sought to diversify its energy sources, including the development of wind power. Additionally, a submarine power-transmission cable established in 2009 connects Hainan to the mainland southern China electricity grid, providing a more reliable and expanded power supply.1
