Where UL Certification is Often Required
Local AHJ often requires UL certified equipment in the following applications:
Inner-City Construction
Why: Fire risk, emissions restrictions, noise ordinances
Where: Cities like NYC, L.A., Boston, Seattle, Chicago, Toronto
Airport Construction
Why: Fire safety, permitting within secure zones, sustainability goals
What: Power terminal expansions, Ground operations & maintenance hangars
Hospital Construction
Why: Fire codes, patient safety, redundancy
What: Power for temporary facilities, expansions, disaster response
Film & TV Production
Why: Quiet, emission-free, code-compliant power for on-location shoots (especially in dense urban areas like LA and NYC)
What: Lighting, trailers, equipment
Events, Festivals, and Stadiums
Why: High occupancy, public safety, fire marshal approvals
What: Power for stages, food trucks, lighting
Government & Municipal Projects
Why: Must meet public safety standards, insurance requirements
What: Infrastructure upgrades, roadworks, emergency power
What You Need to Know
What is the UL standard for energy storage?
UL9540 is the UL standard for energy storage systems. It applies to complete Energy Storage Systems (ESS), including Mobile Battery Energy Storage Systems (MBESS), assessing the integration of batteries, power conversion equipment, and control systems.
What is UL 9540 standard for energy storage systems and equipment?
UL9540 is the safety standard for Energy Storage Systems (ESS), including MBESS. It applies to complete systems and assesses the integration of batteries, power conversion equipment (PCE), and control systems. It also references installation codes such as NFPA 70 and NFPA 855.
What is the difference between UL 9540 and UL 9540A?
UL9540 is the system-level safety standard for Energy Storage Systems (ESS). UL9540A is a fire safety testing method that evaluates fire and explosion risks, especially for systems exceeding standard energy capacities or installed in sensitive environments.
What is the NFPA for energy storage systems?
NFPA 855 is the fire code for energy storage systems. It provides guidelines for installation, spacing, fire detection, and suppression for Energy Storage Systems (ESS) and references UL9540 and UL9540A for compliance and testing.
What is UL 9540A battery energy storage system test method?
UL9540A evaluates fire and explosion risks, particularly thermal runaway and fire propagation. Testing can be performed at the cell, module, unit, or installation level. It is often required for systems over certain capacities or in specific installations.
Which states require UL 9540?
Many forward-thinking cities—such as New York City, Los Angeles, Boston, Seattle, and Chicago—frequently require UL9540 and UL9540A compliance for permitting in sectors like construction, healthcare, events, and film production. These standards are often enforced by local Authorities Having Jurisdiction (AHJs) to support safer, quieter, and more sustainable power solutions. Choosing UL9540-certified equipment helps ensure faster approvals and alignment with the highest safety expectations in these regions.
What key safety features should a UL listed Mobile BESS include?
These are the key safety features to prioritize in Mobile BESS:
- Corrosion-resistant, robust enclosures
- Fire mitigation verified by UL9540A
- Ventilation and gas detection (NFPA 855-compliant)
- External warning systems for large systems (≥500 kWh)
- Safe remote software update capability (UL5500)
