Battery storage fire at solar site takes hours to extinguish

EIR-0141

Provisional entry. Confirmed: a fire occurred at an indoor NMC battery storage system co-located with a solar plant in South Korea in March 2021 and took about three hours to extinguish. Not yet confirmed: the cause of the fire, capacity, injuries, and any investigation findings, as only a headline and a database summary are currently available. Next update: 9 September 2026.

In March 2021 a fire broke out during the afternoon at a battery energy storage system installed at a solar power plant in South Korea. The system used nickel manganese cobalt (NMC) lithium-ion cells and was housed indoors alongside the solar installation. Fire services attended and the fire was reported as fully extinguished after approximately three hours. The cause was not established at the time of reporting. No details on injuries, extent of damage or subsequent investigation findings were available in the source record.

Not reported. The source stated that the cause of the fire was unknown at the time of the report.

  1. Indoor battery installations co-located with solar generation should have detection and suppression provision sized for thermal events lasting several hours, not for short duration fires.
  2. Attending fire services should be briefed in advance on lithium-ion battery fire behaviour at the site, including expected burn times, water supply needs and safe standoff, so that tactics are agreed before an incident.
  3. Operators of similar cell chemistries and enclosure layouts should record and share internal findings from such events, since public source records often close without a stated cause and offer no transferable detail.
