Committee weighs data‑center package that would require tariffs, pre‑funding and strong environmental commitments

Senator Padilla presented a package aimed at preventing cost shifting from large data‑center loads to ordinary ratepayers and at establishing standards for community and environmental protections. "This bill would require the PUC to create special tariffs for large energy users like data centers to protect ratepayers from cost shifts and stranded asset liabilities," the senator told the committee.

Key elements discussed included prohibitions on cost shifting to nonparticipating customers, pre‑funding requirements for long‑term clean‑energy procurement by large customers, demand‑response participation, assignment of certain grid upgrade costs to the large customer, and penalties or early‑termination financial obligations if a project cancels. The author said the bill would also direct the PUC to ensure these customers contribute to nonbypassable costs (including wildfire mitigation) and would require participation in programs that reduce grid strain.

Supporters — including labor, environmental groups, and some local governments — argued the measures are necessary to keep communities whole and to avoid the experience seen in other regions where rapid data‑center buildouts raised costs for other customers. "This bill establishes a robust framework for preventing adverse impacts from data‑center load growth," said a sponsor representative.

Industry groups, Silicon Valley trade organizations and several utilities said the bill as drafted is premature and risks duplicating or conflicting with ongoing CPUC and CAISO proceedings (including Rule 30 and transmission‑cost allocation work). They raised concerns about upfront funding mechanisms and how to assign transmission network costs that serve many customers; PG&E asked that the bill not preempt or contradict technical work already underway at the CPUC.

The committee accepted multiple amendments that narrowed some procurement mandates and moved several operational details toward regulatory implementation, and it placed the package on call to allow absent members to add votes. The author and stakeholders agreed to continue negotiations to reconcile statutory direction with existing CPUC processes.

What’s next: SB 886 (and related bills) was taken as amended and placed on call; sponsors and opponents will continue discussions to refine definitions of attributable transmission costs, pre‑funding mechanisms and CEQA streamlining criteria.
