China has etched its name in renewable history by grid-connecting the first-ever 20MW offshore wind turbine-set, located in Fujian’s southern seas. Per China Three Gorges Group, this ultra-high-capacity unit’s flawless commissioning opens new frontiers in marine wind power.
Defying deep-sea challenges at over 30 km from shore and 40+ meters deep, the turbine’s hub reaches 174 meters skyward—like a 58-story behemoth—with blades forming a 300-meter circle equivalent to 10 football pitches. It churns out excess of 80 GWh annually, meeting needs of 44,000 households while cutting 22,000 tons of coal consumption.
Homegrown airfoil blades, optimized with lightweight and AI-driven integration, cut per-MW weight by more than 20% versus peers, elevating both capture efficiency and output. This bolsters technical readiness for expansive deep-ocean wind ventures.
A testament to China’s end-to-end mastery in giant turbine innovation, the project signals accelerating progress in offshore renewables. Globally, it inspires scaled-up clean energy to meet rising demands sustainably.
