View DetailsFor a Lithium-ion Battery Energy Storage System (BESS), the components must comply with all codes and standards relevant to the operation and installation of energy storage equipment. All installed equipment must be tested and approved by Underwriters Laboratories (UL) or another nationally recognized testing facility.
Discussions with industry professionals indicate a significant need for standards ” [1, p. 30]. Under this strategic driver, a portion of DOE-funded energy storage research and development (R&D) is directed to actively work with industry to fill energy storage Codes & Standards (C&S) gaps.
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].
Energy storage systems continue to be a rapidly evolving industry. Thus, the key to safe and up-to-date compliance requirements involves the adoption and application of codes and standards in addition to the development or writing of codes and standards.
International Building Code (IBC): Following IBC 2024 Chapter 27 Section 2702.1.3, emergency or standby power systems must be installed following the guidelines outlined in the International Fire Code IFC), NFPA 70: National Electrical Code (NEC) and NFPA 111: Standard on Stored Electrical Energy Emergency and Standby Power Systems.
The battery system must follow the current National Electrical Code requirements: NFPA 855, “Standard for the Installation of Stationary Energy Storage Systems”. The battery cell complies with UL 1642, “Standard for Lithium Batteries”. The battery module complies with UL 1973, “Batteries for Use in Light Electric Rail Applications and Stationary Applications”.
