Summary

Official abstract published by the California legislature· summary

Existing law requires the State Energy Resources Conservation and Development Commission (Energy 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 Energy Commission to establish a process for the owner of a data center, as defined, to submit the power usage effectiveness ratio, as defined, for the data center to the Energy Commission on a biannual basis, and require the owner of a data center to submit this information for the data center in the manner and timeframe specified by the Energy Commission. The bill would require the Energy Commission, as part of the 2027 edition of the integrated energy policy report, to include an assessment of electrical load trends for data centers, as provided. Existing law vests the Public Utilities Commission (PUC) with regulatory authority over public utilities, including electrical corporations. Existing law authorizes the PUC to fix the rates and charges for every public utility, and requires that those rates and charges be just and reasonable. This bill would require the PUC to assess the extent to which electrical corporation costs associated with new loads from data centers result in cost shifts to other electrical corporation customers, as provided, and require the PUC, on or before January 1, 2027, to submit the assessment to the relevant policy committees of the Legislature and to publicly post a copy of the assessment on the PUC's internet website. 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.
