The bill establishes a comprehensive framework for the regulation and safety of Battery Energy Storage Systems (BESS) and electric vehicle (EV) chargers in Massachusetts, as mandated by Section 122 of Chapter 239 of the Acts of 2024. It outlines the role of BESS in enhancing electric grid reliability and integrating renewable energy, while detailing the types of technologies, applications, and regulatory requirements for their safe installation and operation. Notably, the bill introduces new legal language that grants the Energy Facilities Siting Board exclusive authority to review and permit large clean energy storage facilities with a capacity of 100 MWh or greater starting July 1, 2026, while smaller facilities will require local permits to be consolidated within 12 months. It also emphasizes fire safety standards, referencing the Massachusetts Comprehensive Fire Safety Code and the National Fire Protection Association standards, ensuring safe operation and installation of BESS.

In addition to BESS regulations, the bill addresses the critical need for EV charging infrastructure to support Massachusetts' greenhouse gas reduction goals. It mandates that all EV charger installations comply with the Massachusetts Electrical Code and the 2023 edition of the National Electrical Code, while also requiring certain chargers to meet federal Energy Star standards. The bill specifies that starting in model year 2026, all electric vehicles sold in the state must include a charging cord of at least 20 feet in length, compatible with Level 1 and Level 2 charging. Furthermore, it includes a reference table of fire safety regulations applicable to both BESS and EV chargers, ensuring a comprehensive approach to safety and compliance in the installation and operation of these systems.
