South Korea's Sinan-Ui offshore wind project (390MW) is facing significant scrutiny over its feasibility, with a capacity factor of just 29.6% while receiving massive public financial support totaling 7.9 trillion won. The project, led by Hanwha Ocean and Korea Midland Power, is drawing criticism from multiple quarters regarding the justification for such substantial government backing given its low operational efficiency projections.
The public funding for the Sinan-Ui project comes from multiple government sources including the Advanced Strategic Industry Fund, the Future Energy Fund, and the Industrial Bank of Korea. This comprehensive financial support package is designed to extend through 2048, locking in long-term subsidies and guarantees for the project's operation over the next two decades.
A major point of contention is that the project has secured long-term fixed-price contracts guaranteeing subsidies without adequate verification of actual power generation capacity. Critics argue that committing to such extensive financial support without concrete validation of the project's generation performance represents poor fiscal management and raises questions about the decision-making process behind the approval.
The project is scheduled to begin commercial operations in January 2029. However, the combination of low capacity factors and the enormous public financial commitment has sparked broader debate about the economic rationality of offshore wind investments in South Korea and whether such projects represent the most efficient use of government resources in the renewable energy transition.
