In a bold stride toward next-generation renewable energy solutions, Chinese state-owned power giant China Huaneng Group has officially launched the world’s most powerful direct-drive floating offshore wind turbine, featuring the largest rotor diameter globally. The unveiling took place in Fuqing, Fujian Province, East China, and was reported by Xinhua News Agency on Thursday.
The turbine boasts a single-unit capacity of 17 megawatts (MW) and a rotor diameter of 262 meters, setting a new global benchmark in offshore wind engineering. With a swept area of around 53,000 square meters, comparable to 7.5 standard soccer fields, the turbine marks a significant milestone in China’s push for offshore wind innovation.
Towering at a hub height of 152 meters, or roughly the height of a 50-story residential building, the turbine is engineered to handle some of the harshest oceanic environments. Its availability rate exceeds 99%, and it can endure towering waves over 24 meters high as well as typhoon-level winds reaching 209 km/h (equivalent to level 17).
“This isn’t just a turbine, it’s a showcase of China’s full-stack manufacturing and systems integration capabilities,” said Liu Xin, director of Offshore Wind Power at the Huaneng Clean Energy Research Institute. Key breakthroughs include the first domestically produced large-diameter main shaft bearing and complete localization of all core components, from blades to transformer.
Crucially, the system also integrates intelligent sensing technology that provides comprehensive stability control, enabling the turbine to operate efficiently in deep-sea conditions exceeding 50 meters in depth. The intelligent system adapts dynamically to environmental challenges, making it a formidable solution for floating wind farms in the Asia-Pacific region and beyond.
The turbine is expected to generate an annual 68 million kilowatt-hours of clean electricity, enough to power approximately 40,000 households. It will soon be towed to waters off Yangjiang in Guangdong Province for final trial and performance validation.
Experts are calling this a manufacturing marvel. Lin Boqiang, director of the China Center for Energy Economics Research at Xiamen University, highlighted how the scale-up in rotor size is not only a technical triumph but also a strategic move to reduce electricity costs per kilowatt-hour. “Larger turbines mean more efficiency and lower costs,” Lin said, adding that China’s coastal provinces like Fujian offer ideal conditions for such deployments due to high wind consistency and readiness for typhoon-resilient infrastructure.
This announcement comes as China continues to reinforce its global leadership in renewable energy. According to the International Energy Agency’s May report, China installed 80 GW of new wind power capacity in 2024 alone. As of May 2025, China’s total installed renewable capacity stands at 2.09 billion kilowatts, more than double the level in 2020, according to the National Development and Reform Commission (NDRC). One-third of the country’s electricity is now generated from green sources, with China leading the world in installed wind turbine capacity.
As the race for renewable dominance accelerates globally, China’s latest offshore turbine isn’t just setting records, it’s setting the pace.
Impressive leap for renewable energy! This turbine is not just big; it’s a game-changer for efficiency and cost. Excited to see China leading the charge in green tech!
