Since 2026, the level of self-sufficiency of key equipment for offshore wind power in China has been continuously improving, promoting the acceleration of offshore wind power development from nearshore to deep offshore.

Recently, the world's largest offshore converter station, Haifengxin, has completed its offshore installation.

The installed offshore converter station can collect the AC power generated by 163 wind turbines in the surrounding sea area, convert it into high-voltage DC power, and significantly reduce power transmission losses, marking China's breakthrough in the problem of high-power transmission in the deep sea. After production, it can deliver approximately 6 billion kilowatt hours of green electricity annually.

With the gradual maturity of offshore resource development, the deep sea is becoming the main battlefield for China's offshore wind power development.

Since 2026, a series of technologies have been accelerating breakthroughs around the deep sea, from core equipment to installation capabilities. The recently installed floating offshore wind power platform with the world's largest single unit capacity has for the first time applied domestically produced special polyester fiber mooring cables, which can withstand a tensile force of about 1300 tons per unit. As of now, China has completed the installation of more than 50 large offshore platforms with a total weight exceeding 700000 tons, achieving all-weather, all sequence, and all sea floating technology.

Next, China will continue to promote innovative development in the upstream and downstream of industries such as large capacity wind turbines, ultra long blades, and dynamic submarine cables, laying a solid foundation for the breakthrough of over 100 million kilowatts of offshore wind power grid connected installed capacity during the 15th Five Year Plan period.
