New Fire Code Tightens Rules for Battery Energy Storage Systems
Released by the National Fire Protection Association (NFPA), it outlines the minimum safety requirements for installing battery storage across commercial, industrial, and
The standard offers comprehensive criteria for the fire protection of energy storage system (ESS) installations based on the technology used, the setting where the technology is being installed, the size and separation of ESS installations, and the fire suppression and control systems in place.
Electrical and Wiring Safety – Proper electrical wiring and connections are critical for fire safety in energy storage systems. NFPA 855 outlines specific requirements for cable management, grounding, and circuit protection to ensure that electrical components do not pose a fire risk.
One proposal for the 2026 edition of NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, would forbid installation of traditional clean-agent or aerosol fire suppression systems unless testing demonstrates that use of such systems does not create an explosion risk.
The energy storage industry is committed to partnering with the fire service to promote safe and reliable operation. From the blueprint of a project site to the specially engineered battery containers, energy storage projects are inherently designed to perform safely and reliably on the grid.
