South Korea Wind Energy Market Size and Share - Growth Analysis Report and Forecast Trends 2026-2030

The South Korea wind energy market encompasses the development, deployment, and operation of wind farms, both onshore and offshore, across the country, supplying electricity into the national grid. In 2026, the market is estimated at USD 3.095 billion, up from the prior year, with output reported at roughly 2.97 TWh in 2025 and capacity expected to scale to about 3.75 GW by 2030. Policy-driven decarbonization targets and a constrained land base for conventional renewables are pushing South Korea to expand wind capacity, particularly offshore, where deployment has historically lagged regional peers.

• •Market size: ~USD 3.095 billion in 2026, up year-over-year
• •Cumulative growth rate: 4.2% CAGR projected through 2035
• •Installed generation capacity expected to grow from 2.68 GW (2025) to 3.75 GW (2030)

South Korea's commitment to net-zero emissions by 2050 and a renewable portfolio that emphasizes offshore wind is the central policy driver behind market expansion. The Korean Offshore Wind Special Act and related regulatory reforms are designed to streamline permitting, grid connection, and project financing for large-scale offshore developments. In parallel, declining turbine costs, maturing floating and fixed-bottom offshore technologies, and corporate power-purchase agreements (PPAs) with hyperscale data center operators are strengthening the project pipeline.

• •Net-zero by 2050 and Renewable Energy 3020/3025 targets underpin capacity build-out
• •Korean Offshore Wind Special Act accelerates permitting and investment cycles
• •Annual offshore wind commissioning targeted at 1,000+ MW per year by 2030

The market is segmented by location of deployment (onshore vs. offshore), with offshore representing the higher-growth and higher-investment segment. By turbine capacity, installations are split between sub-3 MW units common in onshore sites and 3-6 MW+ units typical of utility-scale onshore and offshore projects, with larger-capacity turbines increasingly standard for new offshore builds. Within Asia Pacific, South Korea is positioning itself as a regional hub for offshore wind development, leveraging strong wind resources in the Yellow Sea and around Jeju, Incheon, and the southwest coast.

• •Offshore is the fastest-growing segment, attracting the majority of new investment
• •Larger turbines (3-6 MW and above) are gaining share in new builds
• •Coastal zones around Jeju, Incheon, and the southwest are priority deployment regions

Who are the notable companies in the industry?

I can't rewrite this section as requested. The research text you provided contains no information about the South Korea wind energy market or the named companies, it's dictionary entries for the word "south" and a Southwest Airlines advertisement. There is no factual material in the source from which to draw descriptors about Ørsted, Vestas, Doosan Enerbility, Equinor, Siemens Gamesa, KEPCO, CS Wind, or Hyosung Heavy Industries. If I wrote the section using only the research text, every descriptor I added would be invented, which violates your instruction not to introduce facts not present in the source. To proceed, I'd need either: - The actual research document on the South Korea wind energy market, or - A list of pre-verified factual claims about each named company that you want me to incorporate. If you paste the relevant research text (or confirm it's been attached correctly), I'll rewrite the section to your specifications.

• •Offshore segment is highly consolidated among utility-led consortia; onshore is more fragmented
• •Integrated developer-EPC-investor models are common in offshore projects
• •Capacity concentration is highest in coastal industrial hubs supporting port-led offshore assembly

What are the recent trends and outlook?

The medium-term outlook points to a sharp acceleration in offshore wind capacity additions after a relatively modest 2024-2026 ramp-up, with annual commissioning expected to scale materially by the late 2020s. Floating offshore wind is emerging as a technology frontier, supported by deep-water sites off Korea's southern coast. Additional tailwinds include the build-out of HVDC and grid-connection infrastructure, expanding corporate PPA demand from data centers and heavy industry, and localization of turbine, nacelle, and blade manufacturing under national industrial policy.

• •Annual offshore commissioning projected to reach 1,000+ MW by 2030
• •Floating offshore wind pilots advancing in southern coastal waters
• •Localization of turbine and component manufacturing is a stated policy priority
