In 2016, UL introduced the first edition of UL 9540 as the Standard for Safety of Energy Storage Systems and Equipment. Since then, the International Fire Code (IFC), International Building Code (IBC), and NFPA 1 and NFPA 855 fire codes have all required that electrochemical ESS be listed to UL 9540. 2023 NFPA 855. 15.2 Equipment Listings.
2 July 2023 Codes A variety of nationally and internationally recognized model codes apply to energy storage systems. The main fire and electrical codes are developed by the International Code Council (ICC) and the National Fire Protection
2021 IRC Section R328.2 states: “Energy storage systems (ESS) shall be listed and labeled in accordance with UL 9540.” UL 9540-16 is the product safety standard for Energy Storage Systems and Equipment referenced in Chapter 44 of the 2021 IRC. The basic requirement for ESS marking is to be “labeled in accordance with UL 9540.”
There are other requirements in IRC Section R328 that are not within the scope of this bulletin. 2021 IRC Section R328.2 states: “Energy storage systems (ESS) shall be listed and labeled in accordance with UL 9540.” UL 9540-16 is the product safety standard for Energy Storage Systems and Equipment referenced in Chapter 44 of the 2021 IRC.
The size requirements limit the maximum electrical storage capacity of nonresidential individual ESS units to 50 KWh while the spacing requirements define the minimum separation between adjacent ESS units and adjacent walls as at least three feet.
Individual ESS units shall have a maximum stored energy of 20 kWh per NFPA Section 15.7. NFPA 855 clearly tells us each unit can be up to 20 kWh, but how much overall storage can you put in your installation? That depends on where you put it and is defined in Section 15.7.1 of NFPA 855.
Therefore, if you install multiple storage units, you have to space them three feet apart unless the manufacturer has already done large-scale fire testing and can prove closer spacing will not cause fire to propagate between adjacent units.
NFPA 855 also requires most new Energy Storage System (ESS) installations to be listed in accordance with UL 9540, Standard for Safety of Energy Storage Systems and Equipment. UL 9540 provides design, construction, and performance requirements for ESS.
