Solar photovoltaic (PV) and battery storage systems continue to face persistent technical risks, but many are preventable through better design, data, and quality control. The 2025 Solar Risk Assessment from kWh Analytics outlines several major failure points and. .
The database compiles information about stationary battery energy storage system (BESS) failure incidents. There are two tables in this database: Stationary Energy Storage Failure Incidents – this table tracks utility-scale and commercial and industrial (C&I) failures. Other Storage Failure. .
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. As shown in Figure 1, some 10-15 incidents are reported each year. .
Explore battery energy storage systems (BESS) failure causes and trends from EPRI's BESS Failure Incident Database, incident reports, and expert analyses by TWAICE and PNNL.

EPRI defines failure incident as an oc-currence which resulted in increased safety risk, caused by a BESS system or component failure rather than an exog-enous cause of failure (e.g., wildfire impacting the BESS). The database captures incidents occurring globally and cites information from. .
A Solar Risk Assessment report identifies faults in solar and battery storage and explains how engineers can address them early. Solar photovoltaic (PV) and battery storage systems continue to face persistent technical risks, but many are preventable through better design, data, and quality. .
Between 2017 and 2022, U.S. 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. DNV in their report [2] have learned that many BESS fires are the result of.
