Technical FAQs 4

What are NFPA 855 requirements for energy storage systems?

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.

Are energy storage systems required in the 2015 NFPA 1?

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.

What NFPA codes are required for ESS?

An FAQ overview of US installation codes and standard requirements for ESS, including the 2026 edition of NFPA 855 and updates to UL 9540A.

Is NFPA 855 a fire safety standard?

In a recent article on grid-scale battery energy storage system (BESS) fire safety for our quarterly journal PV Tech Power (Vol.43), Drew Bandhauer, BESS engineer at developer Leeward Renewable Energy, described NFPA 855 as “the primary fire standard guiding BESS site design and installation” for the industry. The latest is the 2026 edition.
