This platform is for educational purposes only. It does not qualify or authorize users to work on battery energy storage systems. BESS equipment presents serious hazards and must only be serviced by properly trained, qualified, and authorized personnel in accordance with applicable codes, standards, OEM requirements, and site procedures.
Course Overview
Battery energy storage systems (BESS) are being deployed faster than ever — on rooftops, at substations, and in communities. But with that growth comes real safety responsibility.
This course gives you a working understanding of NFPA 855, the primary U.S. safety standard for stationary energy storage systems. Whether you’re developing a project, reviewing plans, or just trying to understand what drives BESS design decisions, this course is for you.
If you’ve taken the UL 9540 and UL 9540A: Overview for BESS Applications course, you’ve already seen NFPA 855 referenced as part of the broader compliance picture. This course will cover NFPA 855 in more depth.
By the end of this course, you will be able to:
- Explain what NFPA 855 is and why it was created
- Describe how it fits into the broader code and standards landscape
- Identify the key hazards it addresses
- Understand spacing and setback requirements
- Recognize how the standard shapes engineering and project decisions
- Identify key changes introduced in the 2026 edition
