Are battery energy storage systems safe?

Whether attached to solar power systems or used as a backup generator, battery energy storage systems (BESS) are growing in popularity for homeowners in numerous states. These units may provide safer, cleaner backup power during outages. Like lithium-ion batteries generally, residential BESS may catch fire or even explode.

Are lithium batteries safe?

How to avoid the perfect storm of toxic smoke, rapidly spreading fires, and limited firefighting capabilities presented by lithium battery fires. Energy storage systems have gained a lot of attention in recent years — and so have the enormous safety risks of using lithium-ion batteries.

Can residential battery energy storage systems catch fire?

Like lithium-ion batteries generally, residential BESS may catch fire or even explode. BESS operating software may be a target for cyberattacks which could, in turn, heighten property or liability risks for homeowners. Residential battery energy storage systems (BESS) can serve two overarching purposes for homeowners.

What is a battery energy storage system?

Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.

Are energy storage battery fires decreasing?

FACTS: Energy storage battery fires are decreasing as a percentage of deployments. Between 2017 and 2022, U.S. energy storage deployments increased by more than 18 times, from 645 MWh to 12,191 MWh1, while worldwide safety events over the same period increased by a much smaller number, from two to 12.

Are battery fires dangerous?

CLAIM: Battery fires emit toxic fumes and pose a risk to the community FACTS: Past incidents demonstrate that fires are contained within the facility, and air quality in neighboring areas remains at safe levels. Laboratory testing of emissions from Li-ion cells in thermal runaway shows that emissions are similar to those found in plastics fires.
