Sany Renewable Energy has successfully achieved rated power operation for its SI-270150, the world's largest 15MW onshore wind turbine, marking a milestone in renewable energy innovation.
The SI-270150 features a massive rotor diameter of 270 meters and is designed to operate in medium- to high-wind-speed conditions. With an expected lifespan of 25–30 years, it can generate up to 56 million kWh of electricity annually, assuming an average wind speed of 9 meters per second.
As part of its rigorous testing phase, the turbine will undergo over a year of real-world trials at a test wind farm. This includes approximately 2,000 performance tests to evaluate the reliability of its components and design. Concurrently, a prototype will be subjected to extreme testing on Sany Renewable Energy's cutting-edge 35MW Six Degrees of Freedom & Drivetrain Back-to-Back Test Bench, the largest facility of its kind.
The accelerated lifespan aging tests will simulate 30 years of operational wear within 18 months, ensuring the turbine's durability and performance under demanding conditions.
This development underscores Sany's leadership in advancing renewable energy technologies, with the SI-270150 serving as a flagship model in its 12.X–16.X MW onshore and offshore turbine platform.
