South Korea launches 2025 ESS auction offering 540 MW capacity with 15-year contracts. Learn key requirements, selection criteria, and post-award restrictions.
The project is expected to cost about $725 million (1 trillion won) and will be awarded based on both pricing and non-price factors, such as contributions to domestic industry and battery recycling capabilities.

Less than a decade ago, South Korean companies held over half of the global energy storage system (ESS) market with the rushed promise of helping secure a more sustainable energy future. However, a string of ESS-related fires and a lack of infrastructure had dampened investments in this market.
In terms of battery storage system deployment, South Korea stands among the global leaders. By the end of 2022, the cumulative installed capacity of battery storage in the country had reached an impressive 4.1 gigawatts. In October 2023, the South Korean government unveiled the Korean Energy Storage Systems (ESS) industry development strategy.
In South Korea, various energy storage solutions are used, including pumped hydro, electrochemical batteries, and others. Depending on the energy storage technology and delivery characteristics, an ESS can serve many roles in the electricity market.
But South Korea’s battery industry faces mounting pressure from China, whose manufacturers, led by CATL, currently account for nearly 90 percent of global energy storage battery capacity. CATL expanded its footprint in January by establishing a South Korean subsidiary, signaling an aggressive push into the local market.
In January 2023, South Korea, under a new government, unveiled its biennial master plan, officially known as the "Basic Plan for Long-Term Electricity Supply and Demand" (10th edition). This strategic blueprint sets ambitious targets for renewable energy, aiming for a 21.6% share by 2030 and a more substantial 30.6% by 2036.
The South Korean government, under the auspices of its carbon neutrality and energy transition goals, has launched the 2025 1st ESS Central Contract Market auction, marking an evolution in the country’s battery energy storage system strategy. South Korea has committed to increasing renewable energy capacity while maintaining grid stability.
