Battery storage fire destroys energy storage room at solar site in Cheonan

At around 4:03pm on 12 November 2018, a fire broke out at a solar power facility in Mokcheon-eup, Dongnam-gu, Cheonan-si, South Chungcheong Province, South Korea. The fire involved the site's energy storage room and destroyed 187 lithium-ion battery units. Firefighters extinguished the blaze within approximately two hours. There were no injuries or fatalities reported. Local fire authorities estimated property damage at approximately 154 million Korean won. At the time of reporting, the exact cause of the fire remained under investigation by the fire department. The battery energy storage system, which supported solar integration at the site, had a capacity of 1.2 MWh and had been in operation for under a year prior to the incident.

Not reported. Fire authorities stated the exact cause was still under investigation at the time of publication.

1. Battery energy storage systems co-located with solar facilities require robust fire detection and suppression systems given the potential for rapid escalation in enclosed storage rooms.
2. Early-life system failures, this unit was under one year old, highlight the importance of rigorous commissioning checks and monitoring during the initial operating period.
3. Clear incident investigation protocols and public disclosure of root cause findings help the wider industry learn from failures, even when initial reporting is limited to property damage estimates.
