Chinese company Dongfang Electric has built a 26-megawatt offshore wind turbine, earning the title of “world’s most powerful wind turbine,” a feat previously held by Siemens Gamesa’s 21.5-megawatt turbine in Denmark. Here are the specifications and capacity of the most powerful wind turbine.
The World’s Most Powerful Turbine: Specifications and Capacity
The Chinese state-owned manufacturer announced the installation of this turbine at a testing and certification center. This turbine, the world’s largest in terms of capacity and size, has a blade diameter of over 310 meters and a hub height of 185 meters.

At average wind speeds of 10 meters per second, this massive turbine can generate 100 GWh of electricity per year. This amount is enough to meet the annual energy needs of 55,000 homes. It also reduces the consumption of 30,000 tons of standard coal, preventing 80,000 tons of CO2 emissions. Dongfang states that the turbine can withstand winds up to 17 on the Beaufort scale (200 km/h).
The turbine’s blades have reportedly completed static load tests and are currently undergoing durability testing, with full certification expected to take up to a year. Compared to other turbines, the Dongfang turbine is quite powerful and will be energy efficient.
