Chinese engineers from China Huaneng Group and Dongfang Electric Corporation have created a groundbreaking floating wind turbine prototype capable of generating 17 megawatts (MW)—equivalent to about 68 million kilowatt-hours annually, or enough to power roughly 6,300 U.S. homes, tells LiveScience.com.
Rising 152 meters tall, with an 860-foot (approximately 262 m) blade diameter, each full rotation sweeps an area of 53,000 square meters—comparable to eight soccer fields. This colossal scale enables each turbine to produce significantly more power, reducing the number of turbines needed in wind farms and lowering both installation costs and project durations.
The turbine is engineered to endure extreme offshore conditions, including 78-foot waves and typhoon-strength winds, making it resilient in the harsh environments prevalent in deep-sea settings. This robustness is critical for floating turbines that operate far beyond the reach of traditional fixed-bottom turbines.
Floating wind turbines unlock deepwater offshore wind potential, which constitutes approximately 80% of the world’s offshore energy reserves—territories unreachable by fixed turbines due to greater depths. By enabling deployment in these vast, wind-rich areas, floating turbines can vastly expand renewable energy access, especially for countries with deep coastal waters such as Japan.
Although offshore wind investments typically exceed those of onshore wind, the higher and more consistent wind speeds at sea, combined with fewer service disruptions, translate into greater long-term productivity.
This record-breaking floating wind turbine exemplifies the transformative potential of floating wind technology—scalable, resilient, and ideally suited to unlock vast renewable energy resources in deep offshore environments.
