China’s Dongfang Electric has made a significant advancement in wind energy by installing the world’s most powerful offshore wind turbine, with a capacity of 26 megawatts, surpassing the previous record of 21.5 megawatts held by Siemens Gamesa. This remarkable turbine features an impressive blade diameter of over 310 meters and a hub height of 185 meters, making it the largest in both capacity and size. Designed for optimal performance in locations with strong wind speeds, this turbine has the potential to generate enough electricity to power tens of thousands of homes and significantly reduce carbon emissions.
Dongfang Electric announced the installation of the turbine at its testing and certification facility, where it is currently undergoing extensive testing. The nacelle, which is the heaviest in the world, was shipped earlier this month alongside three large blades. The turbine is specifically engineered for areas with wind speeds of at least 8 meters per second. With average wind conditions of 10 meters per second, it is estimated that a single unit can produce 100 GWh of electricity annually, sufficient to power approximately 55,000 homes. This output can contribute to a reduction of around 30,000 tons of coal consumption and an 80,000-ton decrease in CO2 emissions.
In terms of durability, Dongfang claims that the turbine is capable of withstanding winds up to 200 km/h (17 on the Beaufort scale). The company completed static load testing on the blades back in May and is now conducting fatigue testing to ensure the turbine’s long-term reliability. This ongoing testing process is expected to take up to a year before the turbine receives full certification.
