What happened

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.

Lessons learned

Indoor BESS failures can stay contained when damage is limited to one percent, so operators should verify that enclosure designs limit spread in similar events.
Minor indoor battery events still meet thresholds for tracking, so maintain records of all grid-connected failures to support root cause analysis.
