A California oversight agency is proposing a new policy framework to manage the rapid growth of energy-intensive data centers while protecting ratepayers and maintaining the state’s clean energy targets.
In its report Data Centers and California Electricity Policy, the Little Hoover Commission evaluates how the state should manage rising electricity demand from data centers through updated rate design, financing mechanisms, and regulatory tools. Data centers—particularly those supporting artificial intelligence—are identified as a major new source of load growth and a potential driver of grid investment and modernization.
The report comes as California continues to face some of the highest retail electricity rates in the United States, with prices rising faster than inflation. The addition of large-load customers such as data centers has raised concerns among policymakers about cost allocation, system reliability, and long-term infrastructure planning, and lawmakers have introduced legislation to address these issues.
Ratepayer Protection and Cost Allocation
At the center of the Commission’s recommendations is a directive to ensure that new data center development does not shift costs to existing customers. The report calls for the creation of “very-large-load” tariffs designed to fully recover infrastructure and system costs from data center operators.
These tariffs would incorporate mechanisms such as upfront financial commitments, minimum demand requirements, and exit penalties to reduce the risk of stranded assets. The framework also recommends expanding regulator access to facility-level electricity usage data to improve planning and ensure that cost responsibility is appropriately assigned.
Grid Planning and Siting
To limit unnecessary infrastructure expansion, the report recommends prioritizing the use of existing grid capacity through targeted transmission upgrades and strategic siting of data centers in areas with available capacity. Load-shifting strategies and flexible demand are identified as tools to reduce peak system strain and improve overall grid efficiency.
The Commission also recommends accelerating interconnection timelines for large-load customers while maintaining rigorous review standards to ensure reliability and cost control.
Aligning with Climate Goals
The report emphasizes that new data center load must be integrated in a manner consistent with California’s statutory climate targets. Recommendations include requiring data centers to maintain a minimum level of clean backup power and reducing reliance on diesel generators that can increase local air pollution.
It also calls for statewide standards to limit environmental impacts on nearby communities and to ensure consistent oversight across investor-owned utilities, publicly owned utilities, and community choice aggregators.
Toward a Statewide Framework
The Commission outlines 15 recommendations focused on three areas: ensuring full cost recovery from data centers through tariffs and cost-allocation rules; improving grid planning and siting to maximize existing capacity; and aligning new load with California’s clean energy and environmental standards.
The report also proposes the creation of a public-private research partnership—tentatively named the California Partnership for Advanced Research (CALPAR)—to support the development of technologies that improve the efficiency and environmental performance of AI-driven data centers.
The recommendations position data centers as a test of whether California can accommodate rapid electricity demand growth tied to AI and digital infrastructure without increasing costs for ratepayers or undermining its clean energy transition.
