On November 13, the 7.X MW-222 onshore wind turbine prototype, developed independently by CHN Energy United Power Technology Co., Ltd., successfully rolled off the production line at the Baoding base. This marks the official launch of the 222 series, a key product for the Group, significantly enhancing its competitiveness in the onshore wind power market.
This model was developed based on a mature platform to meet the resource characteristics of large-scale wind farm markets. It boasts advantages such as high power generation, high reliability and strong environmental adaptability. The turbine is equipped with 108-meter ultra-long, lightweight blades with excellent aerodynamic performance, resulting in higher wind capture efficiency and industry-leading power generation capacity among similar products. By adopting a platform-based, universal design approach, and utilizing mature large components from the industry, combined with an intelligent control strategy tailored to large-scale wind resource characteristics, the turbine ensures reliable operation. Additionally, the self-developed integrated ventilation and filtration system for the tower, nacelle and hub combines sand protection, sand removal and ventilation cooling, making it especially suited for environments in desertified areas.
Focusing on the wind power market demand, CHN Energy is committed to deepening its core business in the development of wind turbine equipment. The Group has firmly established a foundation of independent innovation and has made significant strides in tackling key technologies. It has formed a specialized product planning team, scientifically planned its product portfolio, and reshaped the APQP4WIND quality management system to ensure strict quality control during the design phase. At the same time, the Group has established an information-based R&D management system (PLM), enabling full-chain digital management from design to production.
The Group's wind turbine drone inspection system and energy management system have won multiple science and technology awards. The 5 MW–7 MW series onshore wind turbine products received the second prize of the Group's Science and Technology Award, and the Fenghong centralized control system demonstration project won the 2022–2023 National Quality Engineering Gold Award.
As the world's largest coal supplier, thermal power operator, wind power operator and producer of coal-to-liquid and coal chemical products, CHN Energy's technical and economic indicators have reached world-leading or advanced levels. The Group is innovation-driven and continues to build energy technology that is at the forefront globally, supporting national energy security. By optimizing and upgrading traditional industries and developing new future industries, the Group combines technology, talent and capital to achieve a fourfold leap of integration, decarbonization, diversification and high-end development, showcasing the innovative strength of a world-class energy company.
The successful rollout of the 7.X MW-222 wind turbine prototype represents a major milestone in the Group’s technological innovation. It is also a practical step in the Group’s commitment to supporting national energy strategies, building a modern industrial system, and establishing a new development pattern. The Group will continue to lead with innovation, driving high-quality development in the energy industry, and contributing to national energy security and green transformation.
