NFPA 855, Standard for the Installation of Stationary Energy Storage Systems (2023)

Meet the challenges of helping to safeguard the installation of ESS and lithium battery storage by staying up to date on the latest requirements.

NFPA® 855, Standard for the Installation of Stationary Energy Storage Systems, provides insight into mitigating risks and helping to ensure all installations are performed appropriately, taking into account vital life safety considerations. 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.

The 2023 edition NFPA 855 includes the following updates:

• Requirements for fire detection and suppression, explosion control, exhaust ventilation, gas detection, and thermal runaway have been added or revised.
• Requirements from Chapters 4 and 10 specific to electrochemical ESS have been consolidated and reorganized in Chapter 9.
• Chapter 13 has been added to address flywheel ESS.
• Information has been added in Annex B to provide guidance on the hazards associated with additional battery types.
• Annex G has been added as a guide for suppression and safety of lithium-ion battery ESS.
