This achievement marks China’s leading position in the global high-end offshore wind power equipment manufacturing sector.
The turbine represents a comprehensive technological breakthrough in key areas such as the gearbox, generator, and electronic control system, showcasing China’s strong independent innovation capacity in the new energy field and its determination to seize the high ground of global science and technology. It injects powerful momentum into the development of new quality productive forces.
The turbine also demonstrates exceptional power generation efficiency — under full-load operation, each rotation of the rotor can generate 62 kWh of clean electricity. With an average annual wind speed of 10 meters per second, a single turbine can generate up to 100 million kWh annually, sufficient to meet the electricity demand of approximately 55,000 households for an entire year. This is equivalent to saving more than 30,000 tons of standard coal and reducing carbon dioxide emissions by over 80,000 tons, providing strong support for China’s green and low-carbon energy transition.
