Incidents can result from a variety of causes, such as water intrusion, retrofiting errors, operating conditions, cool-ant leaks, temperature stress, quality control, component manufacturing defects and other factors. For meaningful analysis, these causes were grouped into. . The database compiles information about stationary battery energy storage system (BESS) failure incidents. While recent fires aflicting some of these BESS have garnered significant media atention, the overall rate of incidents has sharply decreased,1 as lessons learned. . Battery Energy Storage Systems, or BESS, help stabilize electrical grids by providing steady power flow despite fluctuations from inconsistent generation of renewable energy sources and other disruptions. While BESS technology is designed to bolster grid reliability, lithium battery fires at some. . Since this series was first issued, there have been at least sixteen further incidents of BESS failures1 around the world that have resulted in fires and damage to property, although there are no reports of significant injuries. energy storage deployments increased by more than 18 times, from 645 MWh to 12,191 MWh, while worldwide safety events over the same period increased by a much smaller number, from two to 12.
