�C S A%t Battery Energy Storage Safety <br /> CALIFORNIA ENERGY STORAGE ALLIANCE <br /> background pA 19 0 013 Z <br /> The energy storage industry has proactively worked with fire protection officials and safety experts to <br /> develop test protocols, failure mode effects analyses, state-of-the-art battery management systems, <br /> model codes and standards, and other tools to minimize risks and mitigate potential hazards. Moreover, <br /> energy storage systems (ESS) are very different than battery-powered consumer electronics, and ESS- <br /> related fires are extremely rare. <br /> The National Fire Protection Association (NFPA) includes an entire Chapter (Article 706) related to energy <br /> storage in the 2017 National Electric Code, and CESA successfully advocated for the creation of a new, <br /> standalone NFPA code dedicated to ESS installation - NFPA 855. Additionally, CESA and our members <br /> supported NFPA's recent development of a free online ESS safety training tool for first responders <br /> nationwide. <br /> California Energy Storage Safety Leadership <br /> As the market leaderin ESS deployments,California is also leading development,adoption and implementation <br /> of battery energy storage safety measures: <br /> CPUC convenes Energy Storage Safety Workshop State Fire Marshall submits latest model safety codes from <br /> and publishes website promoting best practices for the International Code Council and NFPA for adoption in the <br /> installing ESS California Fire Code with an entire chapter devoted to ESS. <br /> CA Investor Owned Utility ESS procurement processes AB S46 (Chiu) promotes ESS permitting best practices guid <br /> 1 1 <br /> Ongoing <br /> Canta <br /> Clara County publishes CPUC publishes ESS Safety Cutting-edge ESS RED at UC San Diego <br /> spection Guide Inspection Checklist and Berkeley, Stanford University, and <br /> Lawrence Berkeley National Laboratories <br /> Energy Storage Suppliers Already Implement a Range of Safety Measures <br /> Battery ESS come in a variety of configurations, sizes and chemistries and each system may leverage a <br /> different set of hazard prevention and mitigation measures to minimize risks unique to that system: <br /> Prevention Mitigation <br /> • Cutting edge battery quality research • Fire suppression systems <br /> and testing protocols • Heat, smoke, fire and gas detectors/ <br /> • Advanced battery management systems alarms <br /> • Proper signage and ventilation • Manual disconnect and alarms <br /> • Safety inspector guidelines • Automatic and remote shut-down <br /> • NFPA Codes and Standards • Emergency lighting <br /> UL/IEEE Certifications • First responder training, guildines and <br /> • tools <br /> 0 Fire/incident safety plans <br />
