China accounted for 78% of newly added offshore wind power capacity connected to the grid globally in 2025, maintaining its leading position in the sector, according to a new report released in Shanghai on Wednesday.

The report, entitled Offshore Wind Review and Outlook, showed that 9.252 gigawatts of offshore wind capacity were newly grid-connected worldwide in 2025, showing a 16% year-on-year increase. China contributed 7.192 gigawatts, representing a 78% share of the global total.

By the end of 2025, global cumulative offshore wind grid-connected capacity reached 92.475 gigawatts, with China accounting for 52.042 gigawatts, about 56% of the world's total.

Offshore wind is increasingly transitioning from a supplementary energy source to a core component of the energy system, said Qin Haiyan, secretary general of Chinese Wind Energy Association.

"China is expected to add more than 15 gigawatts of offshore wind capacity annually during the 15th Five-Year Plan period (2026-2030), with cumulative installed capacity to reach 100 gigawatts by 2030," said Qin.

Exports are also growing rapidly. In 2025, China's newly added export capacity of wind turbines reached 7.734 gigawatts, up 48.9% year on year, including 49 offshore wind turbines totaling 225,000 kilowatts.

Zhao Feng, strategy director of Global Wind Energy Council, underscored China's vital role in global offshore wind development. "As we estimate, more than half of new offshore wind capacity over the next decade will come from China."

China's 15th Five-Year Plan has set clear targets for the offshore wind expansion, aiming to further develop large-scale offshore wind bases across the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea, and promote orderly deep-sea offshore wind power development, with cumulative offshore wind capacity expected to exceed 100 gigawatts by 2030.
