Korea’s Offshore Wind Cluster Zones:
Comprehensive Status Report
A full assessment of all 10 Offshore Wind Integrated Zones following the final local government-led designation — and the dawn of Korea’s new Planned Site System era under the Special Act.
Executive Summary
Korea’s Offshore Wind Integrated Zones (OWIZs) now encompass 10 projects totaling approximately 14.4 GW, following conditional designation of 7 new zones on March 15–16 and the Taean designation on March 24, 2026. Collectively, these zones account for 57.7% of the government’s 25 GW offshore wind target for 2035 — crossing the majority threshold for the first time.
The Taean designation marks the final OWIZ under the local government-led framework introduced in 2021. With the Offshore Wind Special Act entering into force on March 26, 2026, all future site designations will proceed through the central government’s Planned Site System, fundamentally restructuring how offshore wind development is initiated, permitted, and executed in Korea.
Covers all 10 designated OWIZs as of March 26, 2026 — zone-by-zone details, developer profiles, permitting comparisons, regional economic impact, and the regulatory transition framework. All 8 March 2026 zones remain subject to military clearance by end of 2026.
