Free Webinar: UL9540 for the Safety of Energy Storage Systems


There are risks associated with energy storage systems as they contain high levels of energy and may utilize hazardous materials, moving parts, etc. As the industry evolves, it is vital that manufacturers, installers, users, insurers and regulators of the energy storage system industry understand the standards in place to ensure that ES systems meet a level of safety rigor necessary to provide confidence that the ES system will operate safely as intended.

Join UL experts for a recorded webinar designed to introduce and explore UL9540, the new standard for safety of energy storage systems, which includes electrical, electro-chemical, mechanical and other types of energy storage technologies for systems intended to supply electrical energy.

UL 9540 provides a basis for safety of energy storage systems that includes reference to critical technology safety standards and codes such as UL 1973, UL 1741, IEEE 1547 and 1547.1, CSA FC1, NFPA 70, NFPA 2, ASME B & PV Code, and ASME B31 piping codes, etc.; and includes additional criteria to address materials, enclosures including walk-in enclosures, controls, piping, utility grid interaction including special purpose interactive systems, hazardous moving parts, signage and instructions. Included are tests for interactive systems, evaluation of electrical spacings and insulation, hazardous moving parts, etc. that may not be covered in current technology standards to more fully address energy storage system safety.

With the emergence of renewable distributive energy such as PV and wind, etc., energy storage systems are a necessary part of the overall energy supply system as they improve the reliability and performance of these renewable sources. ES systems are also being considered as a reliable means to support the utility grid at peak hours without costly enhancement to power generation facilities.

Upon completion of this course, you should be able to:

  • Identify the stakeholders for energy storage system safety
  • Detail which products and energy storage systems technologies fall under the scope of UL 9540 and the corresponding requirements specific to those technologies
  • Explain the approach UL 9540 takes to address ES safety including reference to current codes and standards
  • Describe the construction requirements and tests for ES systems outlined in the standard
