South Korea Targets More Than 100 GW of Renewable Capacity by 2030
The government plans to more than double South Korea’s renewable energy capacity by 2030 while expanding power networks and energy storage to ease grid congestion.
South Korea plans to expand its renewable energy capacity to more than 100 gigawatts by 2030, more than doubling the roughly 40 GW currently available, the Ministry of Climate, Energy and Environment said Tuesday.
The national plan combines additional renewable generation with an expansion of transmission and distribution infrastructure. It also calls for broad deployment of energy storage systems, which can retain excess renewable electricity and release it later when demand or grid conditions make that power more useful.
The ministry said faster growth in advanced industries and the wider electrification of the economy are increasing the urgency of bringing more renewable power online. Yet limited transmission and distribution capacity has constrained the ability to connect and use new supplies, turning the grid into a central challenge for the country’s energy transition.
Under the measures, storage systems would be deployed in areas where existing networks are congested. By absorbing surplus electricity and supplying it at a later time, the systems are intended to help South Korea use more of the capacity already available on its power network while longer-term grid construction proceeds.
Climate, Energy and Environment Minister Kim Sung-whan said the measures are designed to make full use of existing power networks through energy storage rather than waiting for all new transmission infrastructure to be completed.
The approach reflects the different timelines involved in expanding an electricity system. Renewable projects and growing industrial demand can advance faster than major transmission lines, which require planning, approvals and construction. Storage can provide operational flexibility during that gap, although the government is also pursuing new network capacity as part of the broader plan.
Raising installed renewable capacity above 100 GW would represent a significant change in the scale of South Korea’s power mix. The policy’s practical impact, however, will depend not only on how much generation is installed but also on whether the network can move electricity from producing regions to homes, factories and other major users.
The plan therefore treats grid expansion and storage as essential companions to renewable deployment rather than separate projects. The government’s stated goal is to support rising electricity demand while reducing the infrastructure bottlenecks that have slowed wider use of renewable power. The 2030 target gives officials a little more than four years to add over 60 GW from the current level while improving the system needed to carry and balance that electricity.
