EIR-0639Provisional entry. Published from first reports. This entry is rechecked automatically and updated when more sources appear. No further update is scheduled; the entry stays provisional until new information is published.
On 17 December 2018, a fire broke out at a battery energy storage system (ESS) installation in Jecheon, North Chungcheong Province, South Korea. The system, approximately one year old, used nickel manganese cobalt (NMC) lithium-ion cells manufactured by LG Chem in an indoor architecture for demand charge management, with a capacity of 9.3 MWh. An explosion occurred during the incident. This was one of a series of ESS fires reported across South Korea in late 2018, prompting the national government to recommend that all ESS sites not yet subject to detailed safety inspection be shut down until such inspections were completed. No injuries or fatalities were reported in connection with this specific fire.
Not reported in the source. The incident occurred amid a broader pattern of unexplained ESS fires across South Korea in 2018.
- Repeated unexplained fires across similar battery energy storage installations should trigger fleet-wide safety reviews rather than site-by-site responses.
- Regulatory shutdown recommendations following incidents need rapid enforcement, as delays can allow further incidents to occur at other sites in the interim.
- Indoor NMC battery installations used for demand charge management applications warrant enhanced fire detection and suppression measures given demonstrated explosion risk.
