BESS Incidents
To keep the temperature down, an automatic sprinkler system was left running the entire time. A robot was eventually used to open the doors of the container, which kept the responders at a safe distance

Over the past four years, at least 30 large-scale battery energy storage sites (BESS) globally experienced failures that resulted in destructive fires.1 In total, more than 200 MWh were involved in
Rotary energy storage systems, particularly flywheel systems, are the unsung heroes of grid stabilization and industrial power backup. But when failures occur—and they do—the results can
This table tracks other energy storage failure incidents for scenarios that do not fit the criteria of the table above. This could include energy storage failures in settings like electric transportation, recycling,
This report is intended to address the failure mode analysis gap by developing a classification system that is practical for both technical and non-technical stakeholders.
Cell failures can be avoided through careful monitoring of cell voltage, temperatures, and current, to ensure that cells are maintained with their safe operating ranges. Effective and reliable
