NFPA 855: Improving Energy Storage System Safety
855 allows the AHJ to waive many of the prescriptive measures. The LSFT, which is new for 2026, verifies that complete combustion of one enclosure will not cause thermal runaway in.

This article outlines the key safety measures for thermal runaway protection, including explosion venting design and fire-rated wall construction, to ensure system safety.
Battery Energy Storage Systems (BESS) have become, in a few years, an unparalleled solution to remedy the intermittency of certain renewable energies, such as wind farms and photovoltaic
They are designed to provide stored, renewably generated energy at times of high demand. However, along with the benefits which a BESS application
BESS units can be used in a variety of situations, ranging from temporary, standby and of-grid applications through to larger permanent installations designed to support electricity grids
Data from the installation level tests demonstrate the use and effectiveness of deflagration venting for containerized li-ion battery energy storage systems.
By integrating national codes with real-world project requirements, modern BESS container design optimises strength, stability, thermal performance and corrosion resistance,
This Interpretation of Regulations (IR) clarifies specific code requirements relating to battery energy storage systems (BESS) consisting of prefabricated modular structures not on or inside
EXECUTIVE SUMMARY grid support, renewable energy integration, and backup power. However, they present significant fire and explosion hazards due to potential thermal runaway
They are designed to provide stored, renewably generated energy at times of high demand. However, along with the benefits which a BESS application can provide, there is a need to
