On January 19, China's first 12-megawatt onshore wind turbine, named "Lingfeng," was successfully rolled off the production line at the CRRC Songyuan Base in Jilin Province. This marks the country’s first successful manufacturing of a 12-megawatt onshore wind turbine.
The "Lingfeng" turbine is designed with a flexible power range between 11 and 14 megawatts, and its rotor diameter can extend beyond 250 meters. Under typical wind conditions (an average annual wind speed of 7.5 meters per second), the turbine is expected to generate about 38 million kilowatt-hours of electricity annually — a 15% improvement over previous-generation models. This equates to saving 15,000 tons of standard coal and reducing CO2 emissions by 36,000 tons. The "Lingfeng" turbine will significantly boost wind resource utilization in the Shage Desert region, positioning it as a key player in the expansion of onshore wind farms.
Wang Dian, Deputy General Manager of CRRC Qihang New Energy Technology Co., Ltd., noted, “The 'Lingfeng' turbine has overcome several industry challenges, including the design of long, flexible blades and the logistics of lifting and transporting large turbines. Its standout features include high reliability, modular design, advanced intelligence, environmental adaptability, and excellent grid compatibility, making it a comprehensive solution for clean energy generation.”
To address the extreme environmental conditions of the desert, Gobi, and areas prone to sandstorms, wind erosion, and intense ultraviolet radiation, the development team has introduced high-performance protective materials for the leading edges of the blades, along with a comprehensive dust-sealing and surface protection system. These advancements greatly enhance the turbine’s durability and resistance to environmental degradation. Additionally, the turbine is designed for high grid adaptability, ensuring stable operation even in complex grid environments characterized by fluctuating loads and varying line impedance. This makes it a valuable asset for ensuring the reliability and stability of the power grid.
Wang Dian added, “The Shage Desert region is located far from major power loads, and its grid infrastructure is relatively underdeveloped. Developing wind turbines that are specifically designed for the unique conditions in this area will enhance the integration of wind energy into the grid, improve grid flexibility, and support the large-scale adoption of renewable energy.”
