NFPA 855 is the leading fire-safety standard for stationary energy-storage systems. It is increasingly being adopted in model fire codes and by authorities having jurisdiction (AHJs), making early compliance important for approvals, insurance, and market access. This is where the National Fire Protection Association (NFPA) 855 comes in. In this blog post, we'll dive into what NFPA 855 is, why it's important, and the key. NFPA is keeping pace with the surge in energy storage and solar technology by undertaking initiatives including training, standards development, and research so that various stakeholders can safely embrace renewable energy sources and respond if potential new hazards arise. NFPA 855: Standard for the Installation of Stationary Energy Storage Systems (ESS), produced in updated form on a three-year cycle, provides minimum. 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).
