Abstracts

The South Korea energy market size reached 623.7 TWh in 2025. Looking forward, IMARC Group expects the market to reach 832.9 TWh by 2034, exhibiting a growth rate (CAGR) of 3.27% during 2026-2034. The market is experiencing significant growth driven by strong push toward renewables, nuclear expansion, and cleaner technologies. Policy reforms, energy security goals, and decarbonization efforts are further shaping future investments and diversifying the country’s overall energy mix.

SOUTH KOREA ENERGY MARKET TRENDS:

Shift Toward Renewable Energy

South Korea is accelerating its transition toward renewable energy as part of its broader strategy to reduce dependence on fossil fuels and lower carbon emissions. This shift is the main driver of South Korea energy market growth, reshaping the country's energy mix and investment landscape. Solar and wind power are receiving increased support through government-backed incentives, while hydrogen is emerging as a major pillar of clean energy development. Infrastructure upgrades, such as smart grids and energy storage systems, are being rolled out to support the integration of intermittent renewables. The government’s long-term carbon neutrality goals are prompting utilities and private sector players to pivot toward greener alternatives. Reflecting this momentum, significant foreign investment is being directed toward large-scale renewable projects. For instance, in March 2025, Vena Energy announced a major investment in South Korea's renewable energy sector, including $300 million for the 384MW Yokji Offshore Wind Project in South Gyeongsang Province. The project aims to enhance energy security and carbon neutrality while fostering local partnerships and economic benefits. Construction of the 500MW Taean Offshore Wind Project is set for next year. This trend is also influencing domestic manufacturing, R&D, and international collaboration. The ongoing push for clean energy diversification is expected to strongly shape the South Korea energy market outlook in the coming years.

Nuclear Energy Expansion

South Korea is reinforcing its commitment to nuclear energy as a key part of its strategy to ensure energy stability and meet climate goals. For instance, in February 2025, South Korea’s Ministry of Trade, Industry and Energy announced an increase in financial support for its nuclear industry, providing KRW150 billion this year. This follows a commitment to sustain nuclear power's share in the energy mix at 30% by 2030 and plans for the construction of Shin Hanul units 3 and 4. Nuclear power is viewed as a reliable, low-emission alternative to fossil fuels, capable of supporting base-load electricity demands without the variability seen in renewables. The government is not only extending the life of existing reactors but also restarting paused construction and planning new projects. Nuclear technology exports are also being prioritized, with South Korea aiming to become a global player in reactor development. Public and political support for nuclear has grown, especially as energy security becomes more critical. Investment in workforce development and safety upgrades further underlines its long-term role in the country’s energy mix. These moves are set to maintain and potentially increase nuclear’s contribution to the South Korea energy market share over the coming years.
