We are currently conducting prototype demonstration for the 10MW-class turbine and aim to obtain international standard (IEC) certification (type certification) by the first quarter of next year.
Unison's booth at "Smart Energy Plus (SEP) 2026," which opened on the 28th in Hall B of COEX in Samsung-dong, Seoul. A wind turbine model towering over visitors stood in one corner of the booth. This exhibit, with its three white blades reaching toward the exhibition hall ceiling, is a model of Unison's independently developed 10MW (megawatt)-class offshore wind turbine, the "U210."
The actual U210 has a rated output of 10MW and a rotor diameter of 210m. This means the circle traced by the rotating blades has a diameter of 210m. It employs a "gearless" design that directly drives the generator without a gearbox. According to the company, this reduces the risk of failures associated with gearboxes while enhancing durability and reliability.
The design also accounts for domestic offshore conditions, such as typhoons. It is designed to withstand extreme wind speeds of 70 meters per second and has a design life of 30 years. Key systems are duplicated to minimize turbine downtime in the event of a failure.
According to Unison, the U210 began prototype demonstration and power generation in August at a test bed located in Yeonggwang-gun, South Gwangju Metropolitan City. It is currently generating electricity under actual operating conditions to verify its performance. A company official met at the booth stated, "We are aiming to obtain type certification for the 10MW turbine by the first quarter of next year," adding that the project is at a stage where it faces major hurdles toward commercialization.
In wind turbines, Type Certification is a quality license in which an accredited institutional investor officially stamps approval, confirming whether a wind generator can produce electricity without failure for more than 20 years even in rough seas or strong winds. If certification is obtained as planned, the foundation for the full-scale supply of domestic 10MW-class turbines will be established.
Alongside independent development, Unison is also pursuing product line expansion through technical cooperation. Based on a technology transfer and licensing agreement signed with Germany's VENSYS for 13.6 to 16MW-class offshore wind turbines, the company plans to supply 25 units of 13.6MW-class turbines to the Hanbit Offshore Wind project, which was selected in this year's first-half offshore wind competitive bidding.
Through such product lines, Unison is planning to secure a business base of 6.13GW (gigawatt) in offshore wind and 1.97GW in onshore wind by 2030. The company also plans to expand its operations and maintenance (O&M) business.
A Unison official stated, "As a wind power industry player, we are participating in the government's Korea Green Transformation (K-GX) strategy," adding, "We plan to build a full-cycle offshore wind supply chain in cooperation with parts and equipment companies and expand domestic production bases."
This event, hosted by the National Assembly Hydrogen Economy Forum and co-organized by Money Today and COEX, will be held at COEX Hall B until the 30th.
