Doosan Enerbility is nearing completion of South Korea’s largest-ever offshore wind turbine, challenging the dominance of foreign manufacturers in a market the company estimates could be worth 100 trillion won ($72.5 billion) domestically by 2030.
The 10MW turbine, which stands 230 meters tall with a 205-meter blade rotation diameter, has been undergoing demonstration testing in Yeonggwang since February. Doosan plans to secure international certification and begin commercialization within the year, positioning itself as the country’s leading wind energy producer.
Engineers designed the massive turbine specifically for Korea’s low wind-speed environment. The model can achieve electricity generation efficiency of 30% or higher even when average wind speeds are only 6.5m/s, making it suitable for local conditions where foreign designs often underperform.
The company is pursuing component localization aggressively. Through partnerships with state-owned power companies and small enterprises, Doosan aims to reach 70% locally-manufactured components by next year while investing 50 billion won ($36.2 million) in reliability testing and manufacturing upgrades.
Korea faces a significant clean energy challenge. Current offshore wind capacity stands at just 0.1GW, while the government targets 14.3GW by 2030. This ambitious goal requires approximately 7 trillion won ($5.1 billion) investment per gigawatt of capacity.
Doosan isn’t stopping at 10MW. Last month, it partnered with global leader Siemens Gamesa to jointly build a 14MW wind turbine plant in Changwon, further expanding its technological capabilities in the offshore wind sector.
