Apr 21, 2021 · III. Korea ESS Market Overview ESS have been widely installed in Korea since 2017 driven by Government Program such as RPS, REC and ESS Incentive program.

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.
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.
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.
The Gyeongsan Substation – Battery Energy Storage System is a 48,000kW lithium-ion battery energy storage project located in Jillyang-eup, North Gyeongsang, South Korea. The rated storage capacity of the project is 12,000kWh. The electro-chemical battery storage project uses lithium-ion battery storage technology.
South Korea is ramping up its battery energy storage deployment with a new 540MW tender to stabilize the grid and support renewable energy growth. Learn how this move strengthens both domestic resilience and global market leadership.
Deploying long-duration storage will allow Korea to capture surplus renewable energy during these off-peak periods and shift it to peak demand hours, reducing curtailment and maximizing asset utilization. This tender fits within South Korea’s broader decarbonization roadmap.
