Unison, a leading wind power company, announced on the 25th that it has received certification for its 10MW offshore wind turbine design from UL Solutions, a quality evaluation agency certified by the Korea Energy Agency. The wind turbine, named “U210,” is currently being assembled at Unison’s Sacheon plant.
The U210 features a gearless design, ensuring low failure rates and extended durability. It adheres to the latest International Conference on Electrical Standards (IES) and Korean Industrial Standards (KS). With a rotor diameter of 210 meters and a design life of 30 years, the turbine is capable of withstanding wind speeds of up to 70 meters per second, making it suitable for the local maritime environment. The turbine’s design maximizes energy production by minimizing downtime through a major component multiplexing system.
Performance tests on key components, such as the permanent magnet generators, have been successfully completed, and parts certification has been obtained. Unison has now established the necessary technology for the production of gearless offshore wind turbines.
The company plans to finish assembling the 10MW turbine prototype by the second half of this year, with type testing and certification expected to be completed by the first half of next year. Full commercialization is planned for the near future. Ahn Dong-hyuk, Unison’s Technology Director, emphasized that the design certification validates the product’s technological excellence and will strengthen its competitiveness in both domestic and international wind markets.
