Doosan Enerbility Achieves Korea's First International Certification for 10MW Offshore Wind Turbine

Utilization Rate Exceeds 30% Even at Low Wind Speeds of 6.5 m/s
Localization Rate Rises from 30% to 70%

Doosan Enerbility announced on July 23 that its self-developed 10-megawatt (MW) offshore wind turbine has received type certification from the international certification body UL. This marks the first time a Korean company has obtained international certification for a 10MW-class offshore wind model.

The newly certified 10MW model is an advanced version of the 8MW model developed by Doosan Enerbility in 2022. Demonstration of the model began in Yeonggwang, Jeollanam-do in February. After completing on-site demonstration tests in April and verifying design and test data, the company obtained international certification. The model features a blade rotation diameter of 205 meters and an overall height of 230 meters, equivalent to an 80-story apartment building. It is designed to achieve a utilization rate of over 30% even in low wind speed environments of 6.5 meters per second.

Doosan Enerbility began its offshore wind business in 2005 and has supplied offshore wind turbines for the Jeju Tamra (30MW) project in 2017, the Jeonbuk Southwest (60MW) project in 2019, and the Jeju Hallim (100MW) project scheduled for 2025, holding the record for the most offshore wind installations in Korea. During this process, the company increased the localization rate of components from about 30% in the early stages of the business to over 70% today, contributing to the development of the domestic offshore wind ecosystem.

Son Seungwoo, head of Doosan Enerbility's Power Service BG, stated, "With the development of the first 10MW offshore wind turbine in Korea, we have laid the foundation to contribute to the government's renewable energy expansion policy." He added, "Since this achievement was made together with over 150 domestic partner companies, we will take the lead in revitalizing the domestic supply chain through active business expansion."

Meanwhile, in February, the government announced the 11th Basic Plan for Electricity Supply and Demand, setting a target to expand wind power generation capacity to 40.7 gigawatts (GW) by 2038. Currently, Korea's cumulative installed wind power capacity stands at only 2.3GW, indicating rapid expansion is expected. The government is actively promoting the adoption of offshore wind power through policies such as the "Offshore Wind Power Special Act," the "Acceleration of Renewable Energy-Centered Energy Transition," and the "Energy Expressway Construction."
