On August 21, the world's first Mingyang Tianqi MCD5.0MW ultra-low wind speed wind turbine, independently developed and manufactured by Mingyang Smart Energy, was officially rolled off the production line at Mingyang Group's Guizhou base. As the first flagship product of the Mingyang Tianqi series, this turbine inherits Mingyang's "two highs and one low" philosophy of high power generation, high reliability, and low levelized cost of energy (LCOE), fully adopting Mingyang's new-generation medium-speed compact semi-direct drive technology roadmap. Targeting industry pain points and customer needs, it is specifically designed for ultra-low wind speed regions, marking a milestone in advancing global ultra-low wind speed wind power technology innovation and expanding the development and utilization potential of wind energy in ultra-low wind speed areas. Leaders from the Qiandongnan Prefecture Party Committee and Government, Danzhai County Party Committee and Government, and upstream and downstream industry chain enterprises jointly witnessed the turbine's rollout.
Tianqi Leading the Way: First Flagship Product Featuring the World's Best Drivetrain
As a global leader in semi-direct drive technology, Mingyang has been deeply engaged in this field for nearly two decades. During the Beijing Wind Energy Exhibition in October 2025, Mingyang officially launched its new-generation Medium-speed Compact Drive (MCD) technology products. In the same year, this product was awarded the Gold Award for "World's Best Drivetrain" in 2025 by Windpower Monthly, an internationally authoritative wind power media outlet.
The Mingyang Tianqi MCD5.0MW turbine rolled off the production line this time is the first product to fully apply this world's best drivetrain. Centered on the full-lifecycle efficiency, reliability, and economy of wind turbines, the new-generation medium-speed compact semi-direct drive product reconstructs the drivetrain with a minimalist design, reducing the number of components by 60% and significantly improving assembly efficiency. In the core transmission segment, innovative designs such as ultra-large-diameter double-row tapered main bearings, multi-planetary gears with flexible pins, and integrated elbow components effectively reduce gear displacement deformation and overall failure probability, achieving a 10% improvement in reliability. On the operations and maintenance (O&M) front, the modular design of major components supports rapid disassembly and assembly within the nacelle without the need for large lifting equipment, significantly shortening maintenance time and reducing O&M costs.
Riding the Wind in Guizhou: Purpose-Built for Ultra-Low Wind Speed Regions
As one of the earliest OEMs in the world to master high-altitude and low wind speed turbine technology, Mingyang has been deeply rooted in Guizhou for over a decade. As early as 2011, Mingyang developed megawatt-class turbines adapted to Guizhou's mountainous terrain, contributing to the construction of the province's first wind power project to commence construction and first to be put into operation—the Bijie Jiucaiping Wind Farm.
Regions such as Guizhou, Guangxi, and Hunan are endowed with abundant low wind speed wind energy resources. Low average annual wind speeds, insufficient power generation efficiency, and pressure on project economics have long posed development challenges for these resources. How to further lower the developable wind speed threshold and enhance power generation capacity under low wind speed conditions has become a key technological direction for expanding wind power development space.
Through continuous technological innovation, Mingyang has consistently pushed the boundaries of low wind speed development in high-altitude mountainous areas, solving the challenges of developing wind power resources at higher altitudes, lower wind speeds, and higher construction costs.
The Mingyang Tianqi MCD5.0MW turbine is precisely tailored for ultra-low wind speed regions worldwide. With a cut-in wind speed as low as 2.5m/s and a swept area per kilowatt of 7.74m²/kW, the turbine can achieve up to 1,850 annual full-load hours under ultra-low wind speed conditions of 4.5m/s. Designed with ultra-Class A turbulence standards, the turbine leverages top-tier high-performance, long-chord blades synergized with the efficient MCD semi-direct drive drivetrain to achieve a 10% improvement in overall power generation capacity, while reliably and stably coping with extreme climates such as icing and thunderstorms.
Driving the Future with Intelligence: Advancing New Energy Through Technological Innovation
Going beyond hardware innovation, the Mingyang Tianqi MCD5.0MW turbine further integrates AI into turbine operation and wind farm management. Leveraging an AI-powered smart wind farm edge collaboration platform, the turbine enables holistic perception of equipment status, predictive fault detection, and intelligent diagnostics, enhancing fault prevention and handling efficiency. This achieves a 1% increase in power generation and a 5% improvement in revenue, transforming wind farm operations from "post-event response" to "predictive and proactive management."
Tianqi leading the way, driving the future with intelligence. The rollout of the Mingyang Tianqi MCD5.0MW turbine marks a significant starting point for the Mingyang Tianqi product series layout. Centered on the core values of "more reliable, more efficient, more friendly, more intelligent, and more economical," the Mingyang Tianqi MCD medium-speed compact semi-direct drive technology will cover a complete product matrix for both onshore and offshore applications, offering a series of products across different capacity levels and application scenarios to adapt to diverse wind resources and complex environmental conditions, providing more efficient and reliable technical solutions for wind power development.
