WASHINGTON, D.C., March 28, 2025 — Today, the American Clean Power Association (ACP) released a comprehensive framework to ensure the safety of battery energy storage systems (BESS) in every community across the United States, informed by a new assessment of previous fire incidents at BESS facilities.

Are large battery energy storage systems a safety hazard?

The use of large batteries in the domestic environment represents a safety hazard. Even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain,

Are lithium-ion batteries safe for electric energy storage systems?

IEC 63056, recently published by IEC, includes specific safety requirements for lithium-ion batteries used in electrical energy storage systems. These requirements assume that the battery has been tested according to BS EN 62619.

What is a potential risk of domestic battery energy storage systems?

Even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain, the use of large batteries in the domestic environment represents a safety hazard.

Should batteries be used for domestic energy storage?

The application of batteries for domestic energy storage is an attractive ‘clean’ option to grid supplied electrical energy, and is on the verge of offering economic advantages to consumers. This can be achieved by maximising the use of renewable generation or by 3rd parties using the battery to provide grid services.

Are energy storage facilities safe?

“The energy storage industry is committed to a proactive and tireless approach to safety and reliability. At its core, energy storage facilities are critical infrastructure designed to protect people from power outages,” said ACP VP of Energy Storage Noah Roberts.
