Rated for Over 30% Capacity Factor Even at Low Wind Speeds of 6.5 m/s

Doosan Enerbility announced on July 23 that its 10 MW offshore wind turbine model (DS205‑10MW) has obtained type certification from UL, an international certification body. This marks the first time a South Korean company has secured international certification for a 10 MW-class offshore wind turbine.

The certified 10 MW model is an upgraded version of Doosan’s 8 MW turbine developed in 2022. Verification began in Yeonggwang, South Jeolla Province, in February and continued through April, leading to certification based on validated design and test data. The turbine features a 205-meter blade diameter and stands approximately 230 meters tall — the height of an 80-story apartment building. It is designed to maintain a capacity factor above 30% even in low wind conditions of 6.5 m/s.

Since entering the offshore wind sector in 2005, Doosan Enerbility has achieved the most extensive track record in South Korea. It has supplied turbines for major domestic projects including Tamra in Jeju (30 MW) in 2017, the Southwest Coast project in North Jeolla Province (60 MW) in 2019, and the Hallim project in Jeju (100 MW) in 2025. During this period, the company increased the domestic content of turbine components from about 30% to over 70%, thereby contributing to the development of a local offshore-wind ecosystem.

Sohn Seung‑woo, head of Doosan Enerbility’s Power Services BG, stated, “By developing the country’s first 10 MW offshore wind turbine, we’ve laid the groundwork to support the government’s renewable energy expansion policies.” He added, “As this achievement was reached in cooperation with over 150 local partners, we will continue aggressively expanding our business to activate the domestic supply chain.”

Under the 11th Basic Plan for Electricity Supply and Demand in February, the government presented the target of expanding wind power capacity to 40.7 GW by 2038. With current cumulative domestic wind power capacity at only 2.3 GW, rapid growth is anticipated. The government is actively promoting offshore wind deployment through policies such as the Special Act on the Promotion of Offshore Wind Power Distribution and Industrial Development, the acceleration of renewable energy-centered energy transition, and the construction of an “energy highway.”
