6 FAQs about [Battery energy storage safety incidents]
What are battery technology failure incidents?
The focus of the database is on lithium ion technologies, but other battery technology failure incidents are included. Failure incident: An occurrence caused by a BESS system or component failure which resulted in increased safety risk. For lithium ion BESS, this is typically a thermal risk such as fire or explosion.
How to reduce the safety risk associated with large battery systems?
To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.
How dangerous is lithium-ion battery storage?
These incidents represent a 1 to 2 percent failure rate across the 12.5 GWh of lithium-ion battery energy storage worldwide. To better understand and bolster the safety of lithium-ion battery storage systems, EPRI and 16 member utilities launched the Battery Storage Fire Prevention and Mitigation initiative in 2019.
Are battery energy storage systems safe?
Battery Energy Storage Systems (BESS) have become integral to modern energy grids, providing essential services such as load balancing, renewable energy integration, and backup power. However, as with any complex technological system, BESS are susceptible to failures impacting their performance, safety, and reliability.
What are stationary energy storage failure incidents?
Note that the Stationary Energy Storage Failure Incidents table tracks both utility-scale and C&I system failures. It is instructive to compare the number of failure incidents over time against the deployment of BESS. The graph to the right looks at the failure rate per cumulative deployed capacity, up to 12/31/2023.
What causes large-scale lithium-ion energy storage battery fires?
Conclusions Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.
