Cause analysis report of energy storage station fire

Why do energy storage systems have a high risk of fire?

This is due to the rapid development of the energy storage industry and the continuous expansion of capacity demand. The number of large-capacity energy storage systems has increased, and the probability of accidents has increased. There have been many fire accidents of BESS in United States, Australia and China .

What happens if an energy storage station fires?

Since a large amount of energy is stored in the energy storage station in the form of chemical energy, once this energy is released in the form of heat and fire, it will cause serious damage. For example, in 2024, three LFP battery energy storage station fire accidents occurred in Germany within three months .

Are energy storage fire accidents increasing?

Similarly, as the battery energy storage industry develops, energy storage fire accidents are also increasing [16, 19]. Fig. 2 shows the installed capacity and accident data of global energy storage stations in the past decade .

Where can I find information on energy storage safety?

For more information on energy storage safety, visit the Storage Safety Wiki Page. The BESS Failure Incident Database was initiated in 2021 as part of a wider suite of BESS safety research after the concentration of lithium ion BESS fires in South Korea and the Surprise, AZ, incident in the US.

What are the different types of energy storage failure incidents?

Stationary Energy Storage Failure Incidents – this table tracks utility-scale and commercial and industrial (C&I) failures. Other Storage Failure Incidents – this table tracks incidents that do not fit the criteria for the first table. This could include failures involving the manufacturing, transportation, storage, and recycling of energy storage.

What is EPRI's Bess failure incident database?

EPRI’s BESS Failure Incident Database is the main source of data for this report. The database was initiated in 2021 following the series of lithium ion BESS fires in South Korea and the Surprise, AZ, incident in the US. The database gathers information on stationary BESS failure events for commercial and industrial (C&I) and utility-scale BESS.
