What happened
In November 2024 a fire broke out in the afternoon at a battery energy storage system installed at a 1.6 MW solar power facility in Hongnong-eup, Dandeok-ri, Yeonggwang-gun, Jeollanam-do, South Korea. Around fifteen fire engines and dozens of firefighters attended, and the blaze was brought under control after approximately five hours. One battery storage building of about 42 square metres and roughly 560 battery modules were destroyed. No injuries were reported. The facility sits within about 200 metres of residential housing and a community centre for elderly residents, and the proximity of the installation to inhabited areas was raised locally following the fire.
Contributing factors
The source reported that the fire was suspected to have originated from overheating of a large-format lithium iron phosphate battery. The exact ignition mechanism was not confirmed in the source.
Lessons learned
- Large-format lithium iron phosphate batteries can overheat and cause fires that last several hours. Operators should install early detection and allow for extended cooling with many appliances.
- A battery storage building of 42 square metres can be fully destroyed. Operators should design separation to stop fire spread to nearby modules or inverters.
- Sites within 200 metres of housing need clear public risk plans. Operators should review smoke and gas dispersion with local authorities.
