On October 8, a 15-MW onshore wind turbine SI-2701150 self-developed by SANY Renewable Energy (SANY R. E.) was installed in Tongyu, Jilin Province, China. The groundbreaking project set two world records -- the highest single-unit capacity for an onshore turbine and the largest rotor diameter of any onshore turbine ever installed worldwide.

First unveiled at the 2023 Wind Energy Exhibition, the SI-2701150 is a flagship model developed on the 12.X-16.X MW platform. It has a design life of 25 to 30 years. With a rotor diameter of 270 meters and a blade length of 131 meters, the SI-2701150 boasts a maximum swept area of 57,256 square meters, equivalent to about eight soccer fields. The larger swept area boosts its wind capture ability on land, allowing a single unit to generate electricity to power 160,000 households annually.

Cutting-edge technology of the onshore giant

Designed to meet international standards and ensure reliability throughout its entire lifecycle, SI-270150 also boasts advanced technologies. Its lightweight design and intelligent load-reduction technologies reduce the overall load and make it ideal for long-distance land transportation. The drivetrain includes a dual tapered roller bearing integrated main shaft support system, which helps ensure high load-bearing capacity and stability. In addition, the verified dual-transformer-in-nacelle technology also reduces cable usage and land acquisition costs, making the product more economical.

As the pioneer in developing a 15MW onshore wind turbine, SANY R.E. prioritizes safety and reliability. The turbine’s technical feasibility and long-term reliability have been thoroughly validated through extensive multi-tiered testing. Meanwhile, the experimental data was applied to optimize and iterate design and refine digital simulation models to instill a "reliable" gene at the source. The prototype of the 15MW wind turbine will undergo over a year of operational testing at an experimental wind farm to thoroughly verify the reliability of components and the complete system under real-world working conditions.

The successful installation of the onshore 15MW wind turbine marks a milestone in SANY’s development in the megawatt sector and China’s large-scale wind turbines. Looking ahead, SANY R.E. will continue to drive technological innovation with new productive forces, creating high-reliability, highly adaptable smart turbines to support the high-quality development of global wind resources.
