NFPA 855: Improving Energy Storage System Safety
Standard for the Installation of Stationary Energy Storage Systems— now in its recently published third edition (2026)—provides mandatory requirements and explanatory text on energy
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.
While the 2015 versions of the IFC and NFPA 1 do contain some requirements for energy storage systems, they are few compared to the 2018 and 2021 versions. The ESS requirements in the 2018 version, while certainly more restrictive than the 2015 version, are relatively modest.
Energy storage systems, while essential for grid stability and renewable energy integration, present unique challenges when it comes to fire safety. Issues like thermal runaway, short circuits, and the flammability of certain materials can result in fires that are difficult to manage due to the stored energy within the system.
Before diving into the specifics of energy storage system (ESS) fire codes, it is crucial to understand why building and fire codes are so relevant to the success of our industry. The solar industry is experiencing a steady and significant increase in interest in energy storage systems and their deployment.
