This table tracks other energy storage failure incidents for scenarios that do not fit the criteria of the table above. This could include energy storage failures in settings like electric transportation, recycling, manufacturing, etc.
In February 2025 alone, three major energy storage station fire accidents occurred across the U.S., Germany, and the UK – all involving lithium-ion battery systems.
Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions.
Testing for energy storage performance or failure modes is a quanti-tative, objective process, but safety combines objective probabilities with subjective assessment of the acceptability of ever
The availability of root cause information starting in 2018 is an indication of both energy storage industry maturity as well as collective action and scrutiny on lithium ion BESS safety.
The Energy Storage 818 Accident: What It Taught Us About Battery Safety Let''s address the elephant in the room first - energy storage accidents aren''t just technical jargon.
According to incomplete statistics, there have been more than 60 fire accidents in battery power storage stations around the world in the past decade [2], and the accompanying safety risks and
An incident which caused batteries to short has taken offline Phase II of Moss Landing Energy Storage Facility in Monterey County, California, the world''s biggest lithium-ion battery energy storage system (BESS) project.
The infamous 818 accident (you know, the one that turned a state-of-the-art storage facility into an impromptu fireworks display) became the industry''s wake-up call. But here''s the kicker: this wasn''t some isolated "oops" moment. It exposed systemic issues we''re still grappling with today [5].
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 12/31/2024.
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.
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.
4. Planning for Failure Requires Choices: Varying Levels of Over the past four years, at least 30 large-scale battery energy storage sites (BESS) globally experienced failures that resulted in destructive fires.1 In total, more than 200 MWh were involved in the fires.
For context, roughly 12.5 GWh of globally installed cumulative battery energy storage capacity was operating in March 2021, implying that nearly 1–2% of deployed capacity had failed in this way.2 At least one incident resulted in life-threatening injuries to multiple first re-sponders, creating significant backlash for this emerging asset class.
In the United States, a fire and explosion at a BESS facility in Surprise, AZ in 2019 injured four firefighters. 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.
