The turbine has 252-meter diameter blades and a sweeping area of about 50,000 square meters, equaling that of seven standard football pitches, making it the largest such facility in the world. The hub of the turbine is 146 meters high, about the height of a 50-story building.
Under the rated power, each turbine can generate 34.2 kilowatt-hours by turning a single round. Based on the designed average power output in the past few years, each of the 16-MW wind turbine is expected to generate more than 66 million kWh of clean power annually, which can meet the annual power demand of 36,000 households with three family members.
The output equals that produced by burning about 22,000 metric tons of standard coal, which eliminates about 54,000 tons of carbon dioxide emissions. The newly-developed equipment is expected to contribute to realizing China's "dual carbon" goals of peaking carbon dioxide emissions by 2030 and achieving carbon neutrality by 2060, and to promote green transformation and economic and social development.

The turbine was jointly developed by China Three Gorges Corporation and Goldwind.
According to Zhai Endi, chief engineer of Goldwind, the 16-MW turbine has made key technological breakthroughs in development of core components like its large-scale main shaft bearing and ultra-long light blade. The highly-digitalized operation monitoring of the turbines makes it capable of intelligently adjusting the operation mode in response to extreme weather events like typhoons to guarantee safe and highly-efficient power generation.
