Hainan’s installed renewable energy capacity has exceeded 10 gigawatts (GW), now accounting for 45.6% of the province’s total power generation mix, according to figures released by China Southern Power Grid’s Hainan branch.

Hainan’s installed renewable energy capacity has exceeded 10 gigawatts (GW), now accounting for 45.6% of the province’s total power generation mix, according to figures released by China Southern Power Grid’s Hainan branch. This milestone makes renewables the largest single energy source in the island province for the first time.
As a tropical island with abundant wind and solar resources, Hainan is well-positioned to lead China’s clean energy transition. As of May 14, the province had a total of 10.53 GW of installed renewable capacity, including 7.98 GW of solar, 2.09 GW of wind, and 46 MW of biomass.
To support this rapid growth, Hainan Power Grid has rolled out a comprehensive grid integration strategy, offering tailored technical plans and fast-tracked grid connection services. With “one-stop” end-to-end support—from planning and construction to grid commissioning—the time required to bring projects online has been cut by nearly 30%.
Much of this year’s progress has been driven by offshore wind. Since the beginning of 2025, three major wind farms—including the Huaneng Lingao CZ1 and Longhua #1 clusters—have come online at full capacity, adding a combined 2.11 GW to the grid. The province also connected a pioneering grid-forming energy storage facility, supporting the broader effort to stabilize an increasingly renewable-heavy power system.
However, integrating such a large volume of variable energy brings its own challenges. “As wind and solar continue to scale up, their intermittency and volatility pose growing risks to grid stability,” said a representative from Hainan’s Power Dispatch and Control Center. “We’re conducting detailed assessments of system flexibility to ensure that we can safely accommodate more renewable energy.”
