Yes, different safety installation codes and standards are used for energy storage sites with large utility-owned systems where the inverters and batteries are housed in separate locations and the entire project is often far from other buildings. For instance, the 1,600-MWh setup at Moss Landing in California follows these specific codes and standards.
Since the publication of the first Energy Storage Safety Strategic Plan in 2014, there have been introductions of new technologies, new use cases, and new codes, standards, regulations, and testing methods. Additionally, failures in deployed energy storage systems (ESS) have led to new emergency response best practices.
As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry professionals indicate a significant need for standards …” [1, p. 30].
Large-scale energy storage systems pose a greater risk for property and life loss than smaller systems due to their size. NFPA 855 requires 3 ft of space between every 50 kWh of energy storage for safety. However, the Authority Having Jurisdiction (AHJ) can approve closer proximities for larger storage systems based on thermal runaway test results from UL 9540A.
As shown in Fig. 3, many safety C&S affect the design and installation of ESS. One of the key product standards that covers the full system is the UL9540 Standard for Safety: Energy Storage Systems and Equipment . Here, we discuss this standard in detail; some of the remaining challenges are discussed in the next section.
Table 6. Energy storage safety gaps identified in 2014 and 2023. Several gap areas were identified for validated safety and reliability, with an emphasis on Li-ion system design and operation but a recognition that significant research is needed to identify the risks of emerging technologies.
Codes, standards for battery energy storage systems
The ESS must be listed in accordance with UL 9540, the Standard for Safety of Energy Storage Systems and Equipment. This can be indicated by a UL label or a label from another recognized testing authority if it meets the UL standard. IFC 1207.4.12 clarifies that a walk-in BESS enclosure is considered effectively unoccupied. An architect will appreciate this …
