China’s Sany has installed the world’s largest onshore wind turbine with a capacity of 15 MW. The new turbine is reported to have broken records for the largest single-unit capacity and the largest rotor diameter for land-based turbines.
The Chinese heavy construction and equipment manufacturer, Sany Group, has taken a significant step in the energy sector by announcing the installation of the world’s largest land-based wind turbine. According to the company’s October 9 announcement, this massive 15 MW wind turbine, commissioned in China, signals that Chinese companies will continue to push boundaries. Chinese firms have already deployed the world’s largest offshore wind turbines as well as the largest floating offshore wind platform.
Single Turbine, Multiple Records
The SI-270150 model introduced by Sany Group holds the record for the highest capacity among terrestrial turbines with its 15 MW power output from a single unit. It is also noted for being the largest diameter land-based turbine installed globally, featuring a 270-meter rotor diameter. The turbine breaks another record with its 131-meter long blade. With this colossal capacity, a single unit could generate enough electricity to power 160,000 households for a year.
Sany states that this turbine is a prototype and its reliability will be fully verified over the next year through various tests. Designed for a service life of 25 to 30 years, the turbine stands out for its lightweight structure and smart load reduction technologies. These technologies reduce the overall load on the turbine and make it easier to transport long distances by road.
The company also says it used new technologies in the turbine’s manufacturing process. Specifically, automated infusion technology for long distances, 3D design technology used for large composite blades, and recyclable polyurethane structural components increase production efficiency while enhancing environmental sustainability.
Company officials noted that the turbine blade first rolled off the production line in January of this year. Stating that the increase in the 131-meter blade’s size raised the requirements for stiffness and durability, officials highlighted that an optimized aerodynamic profile was used in the design, which minimizes blade vibrations.
