Press Release

Doosan Enerbility announced on July 23rd that it had received type certification from Underwriters Laboratories(UL), the global leader of product safety testing and certification, for its 10MW offshore wind turbine (DS205-10MW model). This marks the first time a Korean company has obtained international certification for a 10MW offshore wind turbine model.

The certified 10MW model is the upgraded version of the 8MW model that was developed by Doosan in 2022. The demonstration of the turbine which was initiated this past February at Yeonggwang, South Jeolla  Province was completed in April, after which the design and test data verification were carried out before the granting of the certification.  The turbine model has a blade diameter of 205 meters and a height of 230 meters, equivalent to an 80-story apartment building. The model was designed to be capable of offering a capacity factor* of 30% or higher even in a low wind speed environment of 6.5m/s.
*Capacity Factor: a performance indicator representing the ratio of the actual electrical energy produced over a one year period to the electrical energy that could have been produced at continuous full power operation during the same period.

Doosan Enerbility first commenced the offshore wind power business in 2005 and since then, it has supplied numerous offshore wind turbines to domestic projects, such as the Jeju Tamra Offshore Wind Farm (30MW) in 2017, Southwest Sea Offshore Wind Farm (60MW) in North Jeolla Province in 2019 and  the Jeju Hallim Offshore Wind Farm (100MW) project in 2025, thereby establishing itself as the largest track record holder for offshore wind turbines in Korea. During this process, Doosan contributed to the cultivation of a robust offshore wind ecosystem in the Korean market by increasing the local manufacturing of parts, which had initially been in the 30% range, to the current 70%+ range.

“By developing Korea’s first 10MW offshore wind turbine, we established the foundation that enables us to contribute to the Korean government’s policy of expanding renewable energy,” said Seungwoo Sohn, CEO of Doosan Enerbility’s Power Services Business Group. “Given that this is a feat that was accomplished together with our 150 partner companies in Korea, we aim to lead the efforts to promote growth of the domestic supply chain for this sector by actively pursuing business expansion.”

The Korean government had presented through the 11th Basic Plan for Long Term Electricity Supply and Demand that was released this past February its intent to increase the installed wind power capacity to 40.7GW by 2038.  As Korea’s installed wind power capacity is currently a mere 2.3GW, rapid expansion is expected to take place. The government is actively pursuing the supply of offshore wind power in the Korean market, as reflected through the proposed policies such as the Special Act on the Promotion of Offshore Wind Power Development and Distribution, Acceleration of Renewables-Oriented Energy Transition, and Construction of the Energy Highway.
