Official Summary Text

AB 1577, as amended, Bauer-Kahan.
Data centers: reporting.
Existing law establishes the State Energy Resources Conservation and Development Commission and vests the commission with various responsibilities with respect to developing and implementing the state’s energy policies. Existing law requires the commission to biennially adopt an integrated energy policy report, as specified, and to make the reports accessible to state, local, and federal entities and to the general public.
This bill would require the commission to establish a process for the owner of a data center, as defined, to submit specified information to the commission, including, among other information, the data center’s location and size, the data center’s power usage effectiveness, as defined, and the quantity of fuel consumed by onsite generators or other fuel-based energy systems, as specified. The bill would require the owner of
a data center to submit the required information in the manner specified by the commission. The bill would require the commission, beginning with the 2029 edition of the integrated energy policy report, and in subsequent editions as deemed appropriate by the commission, to include an assessment of electrical load trends for data centers, as provided. The bill would require the commission to annually publish the information submitted in an anonymized and aggregated format on its internet website.
The bill would require the owner or developer of a data center, upon applying for a discretionary permit, entitlement, or land use authorization required for the construction or operation of the data center, to submit to the applicable local agency, as defined, specified information, including the expected annual energy consumption, as specified, and the expected sound levels attributable to the operation of the data center, as provided.
By imposing a new duty on local
agencies, the bill would impose a state-mandated local program.
The bill would authorize the local agency to use this information for various purposes, including, but not limited to, land use planning, infrastructure planning, energy supply assessment, and environmental review.
The bill would prohibit the commission or a local agency from disclosing information submitted to the commission on a monthly basis or to the applicable local agency upon applying for a discretionary permit, entitlement, or land use authorization, as described above, in a manner that would result in the disclosure of identifiable information or energy consumption data for a data center customer, except as provided.
Existing constitutional provisions require that a statute that limits the right of access to the meetings of public bodies or the writings of public officials and agencies be adopted with findings demonstrating the
interest protected by the limitation and the need for protecting that interest.
This bill would make legislative findings to that effect.
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.
