What are the fire codes for battery energy storage systems?The model fire codes outline essential safety requirements for both safeguarding Battery Energy Storage Systems (BESS) and ensuring the protection of individuals. It is strongly advised to include the items listed in the Battery Safety Requirements table (Fig 3) in your Hazardous Mitigation Plan (HMP) for the battery system.
What are battery-related fire codes and standards?For several decades, governing bodies such as the International Fire Code (IFC), National Fire Protection Association (NFPA), and Underwriters Laboratory (UL) have released battery-related fire codes and standards to ensure and improve public health and safety by establishing minimum standards for fire prevention and protection.
Can a lithium-ion battery energy storage system detect a fire?Since December 2019, Siemens has been offering a VdS-certified fire detection concept for stationary lithium-ion battery energy storage systems.* Through Siemens research with multiple lithium-ion battery manufacturers, the FDA unit has proven to detect a pending battery fire event up to 5 times faster than competitive detection technologies.
Are batteries UL or NFPA certified?In addition, the NFPA (National Fire Protection Association) produces standards documents that focus on electrical safety in relation to batteries. While UL standards are recognized across North America, other regions have similar standards such as IEC 62619 and 62485.
Does NFPA 13 cover lithium-ion batteries?The following is a summary of the lithium-ion battery hazards and the prescriptive sprinkler criteria currently available for each. Since NFPA 13 does not cover fire protection for lithium-ion batteries, the available criteria for fire protection design are limited.
When was a battery energy storage systems fire safety symposium held?We hosted a Battery Energy Storage Systems Fire Safety Symposium on July 24, 2025, at the California Natural Resources Agency in Sacramento, CA. - Updates on state initiatives to local fire departments and officials.
