Are energy storage codes & standards needed?

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.

Does industry need standards for energy storage?

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 pro-fessionals indicate a significant need for standards” [1, p. 30].

What does ul 9540 mean for energy storage systems & equipment?

The third edition of the UL 9540 Standard for Safety for Energy Storage Systems and Equipment, published in April 2023, introduces replacements, revisions and additions to the requirements for system deployment.

How many kWh can a nonresidential ESS unit store?

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.

What is Mesa-device / sunspec energy storage model?

MESA has developed and manages two specifications: MESA-DER (formerly MESA-ESS) and MESA-Device/SunSpec Energy Storage Model . MESA-DER addresses communication between a utility’s control system and distributed energy resources (DERs), including ESSs. MESA-Device specifies standardized communications between components within the ESS.

What are ESS size and separation requirements?

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.
