Should energy storage systems be protected by NFPA 13?
According to the Fire Protection Research Foundation of the US National Fire Department in June 2019, the first energy storage system nozzle research based on UL-based tests was released. Currently, the energy storage system needs to be protected by the NFPA 13 sprinkler system as required.
Are battery energy storage systems safe?
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.
What are the NFPA 855 requirements for energy storage systems?
For example, for all types of energy storage systems such as lithium-ion batteries and flow batteries, the upper limit of storage energy is 600 kWh, and all lead-acid batteries have no upper limit. The requirements of NFPA 855 also vary depending on where the energy storage system is located.
How do you protect a battery module from a fire?
The most practical protection option is usually an external, fixed firefighting system. A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space.
How can battery storage facilities be regulated?
In addition to working with fire officials and state policymakers to advance safety standards, the industry has developed a framework to help local governments effectively regulate the construction of battery storage facilities.
