South Korea has reaffirmed its commitment to accelerate the clean energy transition, placing a strategic focus on deploying 100GW of renewable capacity by 2030 while strengthening grid infrastructure under its 2026 energy transition blueprint.
The updated roadmap aligns with the government’s broader ambition to progressively retire coal-fired generation and modernise the country’s power system. Structural reforms across electricity tariffs and wholesale market design are central to the plan, alongside initiatives aimed at enhancing public confidence and long-term sustainability in nuclear energy.
Grid Reform to Unlock Renewable Integration
A key feature of the strategy is the repurposing of grid connections from retiring coal plants to support faster renewable integration. This approach is expected to reduce connection bottlenecks and accelerate project timelines across wind and solar developments.
In parallel, the government has outlined a just transition roadmap to support communities affected by coal plant closures. Proposed legislation will focus on economic cushioning, workforce transition and regional development as part of a structured and socially responsible shift away from coal.
Electricity Tariff Reform and System Optimisation
South Korea also plans to recalibrate industrial electricity tariffs in early 2026. Evening rates are expected to rise to better reflect peak demand, while daytime rates may ease to optimise load distribution and improve system efficiency.
Nuclear energy will continue to serve as a stabilising component of the national energy mix, operating alongside renewables to ensure grid reliability during the transition period. Authorities have confirmed that new nuclear projects will proceed according to schedule, reinforcing energy security objectives.
A Diversified Energy Mix in Transition
The measures announced will feed into the 2026 to 2040 power supply plan, which charts a gradual coal phase-out within a diversified energy portfolio.
From January to November 2025, coal accounted for 29% of total generation, nuclear for 31%, gas for 28% and renewables for 11%, according to Argus data. Increasing renewable penetration while maintaining system stability will require careful planning, infrastructure investment and skilled workforce deployment.
LSP Renewables Perspective
South Korea’s renewed commitment to 100GW of renewables by 2030 sends a clear signal that large-scale energy transition in Asia is accelerating. Ambitious targets combined with structural reform will require experienced leadership, commercial expertise and technical delivery capability across wind, solar, grid and storage.
For developers, utilities and supply chain partners, this transition creates both opportunity and complexity. Delivering at scale demands the right teams in place from origination and regulatory strategy through to engineering, grid integration and long-term operations.
At LSP Renewables, we support organisations across Asia in building the talent pipelines needed to execute these ambitious plans.
