6 Frequently Asked Questions about “Investigation Report on Energy Storage Fire in Togo”

What did EPRI learn from the Carnegie road energy storage system failure?

In December 2020, EPRI was integrated into the investigation team to advise on battery technology hazards in a supporting role to Ørsted. This report conveys the lessons learned from the Carnegie Road energy storage system (ESS) failure event, including aspects of emergency response, root cause investigation, and the redesign and rebuild process.

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 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 are other storage failure incidents?

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.

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.

Are root cause investigations a priority for the energy storage industry?

Following the incident, multiple root cause investigation reports were released publicly, and safety became a priority issue for the energy storage industry in the US. In the subsequent years, root cause investigations have occasionally been made public to support industry learnings.
