The latest specifications for battery energy storage fire protection solutions

What is the NFPA 855 standard for stationary energy storage systems?

Setting up minimum separation from walls, openings, and other structural elements. The National Fire Protection Association NFPA 855 Standard for the Installation of Stationary Energy Storage Systems provides the minimum requirements for mitigating hazards associated with ESS of diferent battery types.

Does ul 9540a certify a battery energy storage system?

UL 9540A does not certify products. Instead, it offers important data for designing safer battery energy storage systems (BESS). It also helps with following installation codes like NFPA 855. NFPA 855 is the guideline for installing Battery Energy Storage Systems (BESS).

What is a battery energy storage system?

Battery Energy Storage Systems (BESS) have emerged as crucial components in our transition towards sustainable energy. As we increasingly promote the use of renewable energy sources such as solar and wind, the need for efficient energy storage becomes key.

Are battery energy storage systems safe?

WASHINGTON, D.C., March 28, 2025 — Today, the American Clean Power Association (ACP) released a comprehensive framework to ensure the safety of battery energy storage systems (BESS) in every community across the United States, informed by a new assessment of previous fire incidents at BESS facilities.

What are the NFPA 855 fire-fighting considerations for lithium-ion batteries?

For example, an extract of Annex C Fire-Fighting Considerations (Operations) in NFPA 855 states the following in C.5.1 Lithium-Ion (Li-ion) Batteries: Water is considered the preferred agent for suppressing lithium-ion battery fires.

What are the requirements for a fire suppression system?

Key requirements: Location-specific safety: Minimum spacing between systems, setbacks from occupied buildings, and restricted access zones. Fire suppression systems: Requirements for sprinklers, clean agents, or other suppression technologies.
