Washington energy storage charging fire

How many large-scale battery energy storage sites have been affected by fires?

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.

Are battery energy storage fires a silver bullet?

As one of the site hosts indicated, there is no “silver bullet” to address battery energy storage fire and explosion hazards, but rather many solutions are needed. Though the risk of a fault in an ESS may be low, certain issues can never be truly eliminated, and the tolerance to such risk is up to the storage asset’s owner and operator.

Are energy storage sites operational?

EPRI conducted evaluations of energy storage sites (ESS) across multiple regions and in multiple use cases (see Table 1) to capture the current state of fire prevention and mitigation. Of those sites, six are operational, two are under construction, and two are in design.

How can energy storage sites save lives and equipment?

Coordination, planning, and communications before, during, and post-event can save lives and equipment. EPRI conducted evaluations of energy storage sites (ESS) across multiple regions and in multiple use cases (see Table 1) to capture the current state of fire prevention and mitigation.

Is energy storage safety a quanti-tative process?

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-present haz-ards.

Are energy storage technologies ready for commercial use?

Now a new wave of energy storage technologies is advancing to commercial readiness, with expectations that lessons learned from the earlier generations can be captured, codified, and leveraged for their development to smooth adoption and use.
