What happened
At around 18:30 on 20 October 2022, a fire broke out in one of ten battery compartments (No. 6) at the 25MW/50MWh energy storage system forming part of the Hainan Tianneng Yingge Haiyanchang 100MW photovoltaic project energy storage power station in Yinggehai, Hainan, China. The local fire department was notified and firefighters arrived at the site by 18:50. There were no casualties. The energy storage system was still in the commissioning stage, had not been connected to the grid or handed over from the EPC contractor, PowerChina Hainan Electric Power Design, to the operator, Hainan Tianneng Electric Power, so the incident did not affect grid operation.
Technical staff advised that the fire could not be safely extinguished with water at the scene. Because the burning compartment did not threaten surrounding equipment, the decision was taken to let the fire burn itself out before further disposal action.
Contributing factors
The battery system was in the commissioning phase and had not yet been formally handed over to the operator, Hainan Tianneng Electric Power. Reports noted that the site had recently conducted photovoltaic fire emergency drills but appeared to lack specific emergency drills and plans for energy storage battery fires.
Lessons learned
- Battery energy storage systems need fire emergency drills and response plans specific to the chemistry, separate from generic photovoltaic plans.
- Fires can occur during commissioning before handover or grid connection, so protocols must include dedicated fire monitoring and response.
- Water may not be safe or effective for lithium iron phosphate battery fires; agree tactics in advance, including controlled burn-out if isolation is assured.
