NFPA 855: Improving Energy Storage System Safety

NFPA 855—the second edition (2023) of the Standard for the Installation of Stationary Energy Storage Systems—provides mandatory requirements for, and explanations of, the safety strategies and features of energy storage systems (ESS). Applying to all energy storage technologies, the standard includes chapters for specific technology classes.

The depth of this standard makes it a valuable resource for all Authorities Having Jurisdiction (AHJs).

The focus of this fact sheet is on how the standard applies to electrochemical (battery) energy storage systems in Chapter 9 and specifically on lithium-ion (Li-ion) batteries.
