The South Korean government has announced plans to invest $222.6 million (KRW 321 billion) in 2026 to modernize regional electricity networks and expand renewable energy integration. The initiative aims to deploy 85 energy storage systems (ESS) by 2030, with 20 units slated for installation this year, enabling an estimated 485 MW of additional solar connections.

The government will also pilot microgrids for industrial complexes and university districts to flatten demand and improve network efficiency. Small-scale storage will support “sunlight income villages,” promoting localized renewable energy benefits.

Korea Electric Power Corp. (Kepco) will act as the distribution system operator (DSO), using an advanced distribution management system (ADMS) to forecast solar output and dynamically manage storage charging. A pilot non-wires alternatives (NWA) program in Jeju will compensate storage operators when their systems reduce the need for traditional grid upgrades.

Market reforms are planned, including a power demand bidding system and renewable energy bidding trials initially in Jeju, with eventual expansion to the mainland.

The government is also building a domestic ecosystem for next-generation grids through the K-Grid talent and startup cluster, testbeds, and the K-Grid Future Festival. Cooperation agreements with universities and energy agencies will support workforce development and coordinated storage operations.

This investment is part of a broader transformation of South Korea’s electricity system, with energy storage, digitalization, and domestic manufacturing emerging as strategic priorities. Kepco completed a 978 MW / 889 MWh grid-stabilization battery system in Miryang in 2024, then the largest in Asia.
