This standard provides the minimum requirements for mitigating the hazards associated with ESS.
It broadens which technologies fall under NFPA 855, clarifies who is qualified to evaluate risk, and makes Hazard Mitigation Analysis (HMA) the default expectation for most ESS projects.
Master NFPA 855 compliance for BESS installations. Learn UL 9540A testing, thermal runaway prevention, and gas detection strategies with real-world case studies.
NFPA is keeping pace with the surge in energy storage and solar technology by undertaking initiatives including training, standards development, and research so that various stakeholders can safely
The codes have been changing rapidly to keep up with the fire and explosion hazards of ESS, and although not outright adopted in most jurisdictions, NFPA 855 sets the standard for
An overview of NFPA 855, a standard that improves energy storage system safety. The 2026 edition of NFPA 855 updates safety and installation requirements for stationary energy storage systems (ESS),
While locally adopted fire codes take precedence over NFPA 855, the depth of this standard—plus the wealth of tutorial information in its annexes—make it a valuable resource for all Authorities Having
These NRECA advisories provide the latest on the process, as well as an overview of the standard and the potential impact on cooperatives:
Fire detection, including smoke and heat alarms, vehicle impact protection with approved barriers, and ventilation requirements for chemistries that produce flammable gas during normal
