South Korea Boosts 2030 Renewables Target to 20% Share, Aims for 100 GW Solar and Wind Capacity

The South Korean government has announced ambitious 2030 targets, aiming for renewable energy to supply at least 20% of electricity and installing a combined 100 GW of solar and wind capacity.

This move is driven by the need to enhance energy security, meet rising electricity demand from industries like semiconductors and AI, and accelerate the country's decarbonization efforts.

Achieving this goal requires a massive scale-up, averaging approximately 13 GW of new capacity per year, a pace supported by recent legislation like the Offshore Wind Special Act.

South Korea's government recently announced a significant acceleration of its energy transition, setting ambitious new renewable energy targets for 2030.

This new plan is substantial in its scope. The government is targeting a renewable energy share of at least 20% of total electricity generation and a combined solar and wind capacity of 100 gigawatts (GW) by 2030. To put this in perspective, renewables accounted for just 10.6% of generation in 2024 with about 35 GW of capacity. Reaching 100 GW means Korea must add an average of 13 GW of new capacity every year from 2026 to 2030—a dramatic increase from its historical pace.

This aggressive push is driven by a clear set of national priorities. First is energy security. As a nation that imports over 90% of its primary energy, South Korea is highly vulnerable to global supply chain disruptions, such as recent tensions in the Strait of Hormuz. Expanding domestic renewable sources is a direct strategy to reduce this dependency. Second is industrial competitiveness. The country's world-leading semiconductor and emerging AI industries have a voracious appetite for electricity. Providing a stable, clean, and increasingly cost-competitive power source is essential to support their growth and meet global supply chain demands for decarbonization.

This announcement did not emerge from a vacuum; it's the culmination of foundational policy work. The 11th Basic Plan for Electricity had already set the stage by outlining a path toward a higher renewable share. More critically, the recently passed Offshore Wind Special Act is a game-changer. By creating a government-led model for site selection and permitting, it drastically reduces the risks and timelines that have historically plagued large-scale wind projects, giving investors and developers the confidence needed for such a rapid build-out.

While the 100 GW capacity target is the headline, the ultimate goal is usable electricity. At full potential, 100 GW could generate far more than the 20% target, but this hinges on modernizing the grid. Without significant investment in transmission lines and energy storage, the risk of curtailment—where wind and solar farms are forced to shut down because the grid is overloaded—grows. Acknowledging these transition challenges, the government will also maintain a small number of coal power plants as "security power" for emergency backup, signaling a pragmatic, albeit complex, path forward.

LCOE (Levelized Cost of Energy): The average lifetime cost of building and operating a power plant, divided by its total electricity output. It helps compare the cost-competitiveness of different energy sources.
Curtailment: The act of intentionally reducing electricity production from renewable sources like solar or wind, typically because the grid cannot absorb the excess power at that moment.
Offshore Wind Special Act: A landmark South Korean law that streamlines the complex permitting process for offshore wind farms by empowering the government to lead site designation and approval, aiming to accelerate development.
