The South Korean Ministry of Climate, Energy and Environment has unveiled a strategy to triple its onshore wind capacity to 6 GW by 2030 (South Korean Ministry of Climate, Energy and Environment press release, 03/12/2025). The plan introduces 10 key actions items, including rationalising regulations, launching public competitive biding for wind projects, expanding guarantees and financing, ensuring fast grid connections and creating an public-led planned site location system for public islands.
The plan aims to reduce generations costs by at least 20% by 2030, reaching a level below KRW150/kWh (US$10c/kWh), and to raise the capacity to 12 GW by 2035. The country has a strong potential for onshore wind, but annual capacity addition are limited to 0.1 GW due to complex permitting and regulatory bottleneck, according to the ministry.
Onshore wind accounted for 1% of South Korea’s capacity mix at end-2024 and less than 1% of its generation mix, according to Enerdata’s Global Energy Research. Around 0.5 GW of onshore wind projects are currently under construction, and more than 5.8 GW under development.
