Large-Scale Fire Testing (LSFT): from best practice to mandatory requirement
- •Large-Scale Fire Testing (LSFT) for Battery Energy Storage Systems (BESS) is transitioning from a best practice to a mandatory requirement, with at least a dozen companies already conducting tests.
- •The 2026 edition of NFPA 855 will mandate LSFT, creating a significant regulatory shift that will impact BESS project design, permitting, and deployment for developers and large power consumers.
- •Developers and large power consumers should anticipate increased BESS project costs, potentially longer development timelines, and new compliance burdens due to these mandatory safety testing requirements.
