The 2026 edition of NFPA 855: Standard for the Installation of Stationary Energy Storage Systems has now been released, continuing the rapid evolution of safety requirements for battery energy storage systems (BESS). Since the first edition in 2020, each cycle has refined how the standard addresses. . These approaches take the form of publicly available research, adoption of the most current lithium-ion battery protection measures into model building, installation and fire codes and rigorous product safety standards that are designed to reduce failure rates. While BESS technology is designed to bolster grid reliability, lithium battery fires at some. . Each battery must meet the requirements of this subpart. [CGD 94-108, 61 FR 28277, June 4, 1996] § 111. (a) A battery cell, when inclined at 40 degrees from the vertical, must not spill electrolyte. Understanding the reasons behind these rules helps reinforce their importance.
