The rate of failure incidents fell 97% between 2018 and 2023, with a chart in the study showing that it went from around 9.2 failures per GW of battery energy storage systems (BESS) deployed in 2018 to around 0.2 in 2023.
There is a growing focus on sustainable energy sources and storage systems. The challenge with such emerging systems is their need to be warrantied for around 15 years with just a year of early

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.
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.
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. Residential energy storage system failures are not currently tracked.
There has been a dramatic fall in failures of stationary battery energy storage over the past 5 years.
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.
