Indoor battery storage system fails in Gangjin County, South Korea
EIR-0107Provisional entry. Published from first reports and rechecked automatically as more sources appear. No further update is scheduled; the entry stays provisional until new information is published.
In March 2025, an indoor lithium-ion battery energy storage system located in Doam-myeon, Gangjin County, Jeollanam-do, South Korea, experienced a failure incident. The site had a total energy capacity of approximately 35 megawatt-hours. According to an industry database that tracks global battery storage failures, the event resulted in damage to about one percent of the installed capacity, indicating a contained and relatively minor failure rather than a total loss event. Public reporting on the specific technical cause, whether emergency services attended the site, and whether any injuries occurred has not been identified. The incident was recorded because it met the threshold used by safety researchers for tracking failures with potential wider public health and safety implications at stationary battery storage installations connected to the grid or used in commercial and industrial applications.
- Indoor battery storage installations require containment, ventilation and fire suppression designs specific to enclosed environments, since even small-scale thermal events can pose risks in confined spaces.
- Operators and regulators benefit from systematic incident tracking, including events causing only minor damage, as aggregated data supports industry-wide root cause analysis and design improvements.
- Timely and detailed public disclosure of thermal incidents, including root cause once known, allows other operators to check for similar vulnerabilities in comparable indoor or enclosed battery installations.
