This section of the report discusses the architecture of testing/protocols/facilities that are needed to support energy storage from lab (readiness assessment of pre-market systems) to grid
One of the Energy Storage Partnership partners in this working group, the National Renewable Energy Laboratory, has moved forward to collect and analyze information about the existing energy storage
What is the UL 9540A Test Method? UL 9540A is a safety standard for energy storage systems and equipment, developed by UL as a test method to evaluate thermal runaway and fire
This report describes development of an effort to assess Battery Energy Storage System (BESS) performance that the U.S. Department of Energy (DOE) Federal Energy Management Program
Our experts are knowledgeable about the relevant standards, and they can guide you through the energy storage system testing and certification process. We also deliver ESS testing and certification
This chapter reviews the methods and materials used to test energy storage components and integrated systems. While the emphasis is on battery-based ESSs, non-battery technologies such as flywheels
Explore the key updates in UL 9540A:2025, including enhanced testing methods and definitions to improve safety in battery energy storage systems and address fire hazards.
The UL 9540A Test Method is the backbone of energy storage safety in 2025. With its updated fifth edition, it provides a clear, science-based framework to evaluate thermal runaway risks
Testing is conducted at the cell, module, unit, and (if needed) system levels. UL9540A provides needed information as specified in NFPA 855 (installation Code) and IFC 2018 (Fire Code).
UL 9540A is a testing procedure that evaluates and documents the fire performance of stationary ESS and was introduced as a compulsory requirement for all residential systems intended for installation
