As the number of Li-ion Battery Energy Storage Systems (BESS) facilities being installed continues to rise rapidly, it’s crucial to address the hazards and risks associated with these facilities during the design, installation and operation phases. AEGIS published our initial white paper on this topic back in 2021. As more BESS facilities are constructed and remain operational for longer periods, we continue to learn from both losses and model practices across our membership. The first revision to the BESS white paper was released in 2023, expanding on the Deflagration Hazard Study (DHS), installation-level testing criteria, and concerns associated with various facility configurations, such as parking garage-style layouts and enclosure stacking. Available now, this second revision contains additional and updated information, including:
As installations and reliance on BESS facilities continues to grow, AEGIS Loss Control remains committed to staying current with industry developments and lessons learned from losses through active engagement with the broader industry, collaboration with our members and their chosen OEMs, and participation in National Fire Protection Association (NFPA) committees. Insights from these sources are shared among our subject matter experts through internal working groups, which help shape external communications for our members. You can find a copy of the updated BESS white paper here.
