Learn MoreU.S. fire and electrical codes require that energy storage systems be listed, meaning the product must be tested by a Nationally Recognized Testing Laboratory (a private-sector organization recognized by the Occupational Safety and Health Administration) and certified to meet consensus-based test standards.
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.
For ESS, the standard is UL 9540, Standard for Energy Storage Systems and Equipment. UL 9540 covers the complete ESS, including batery system, power conversion system (PCS), and energy storage man-agement system (ESMS). Each of these components must be qualified to its own standard:
As the ESS market expands and the demand for long-dura-tion energy storage grows, it is inevitable that new batery technologies and other non-batery systems will be ofered, often with rosy predictions for low cost, improved safety, or other characteristics.
ESS size and separation requirements in particular have been addressed in the second edition of UL 9540. ESS installation codes contain size and separation requirements designed to prevent a fire originating in one ESS unit from propagating to adjacent ESS units or adjacent battery room walls and exposures.
NFPA 484 Standard for Combustible Metals, NFPA 704 Standard System for the Identification of the Hazards of Materials for Emergency Response, Canadian Electrical Code's CSA C22.2 No. 286, and UL 1004-4 Standard for Electric Generators were added as reference standards related to thermal ESS.
