What is CA AB 434 about?
Existing law authorize a person proposing an eligible facility, including an energy storage system that is capable of storing 200 megawatthours or more of energy, to file with the State Energy Resources Conservation and Development Commission an application for certification for the site and related facility, as provided. Existing law provides that the certification issued by the commission is in lieu of any permit, certificate, or similar document required by a state, local, or regional agency for the use of the site and related facility. This bill would exclude energy storage facilities that use batteries as a storage medium from the above-described provisions. This bill would prohibit, until January 1, 2028, a public agency from authorizing the construction of a battery energy storage facility, as defined. The bill would require the State Fire Marshal, on or before January 1, 2028, to adopt guidelines and minimum standards for the construction of a battery energy storage facility to prevent fires and protect nearby communities from any fire hazard posed by the facility. The bill would require a public agency, when authorizing the construction of a battery energy storage facility on or after January 1, 2028, to require the facility to meet the guidelines and minimum standards adopted by the State Fire Marshal or more stringent guidelines and minimum standards as determined appropriate by the public agency. Because the bill would impose additional duties on local agencies in authorizing the construction of a battery energy storage facility, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
