California’s independent bipartisan oversight commission released a report Tuesday urging state policymakers to act quickly on data center regulation before soaring electricity demand from artificial intelligence expansion raises utility bills for ordinary households. The Little Hoover Commission outlined more than a dozen recommendations for managing the fast-growing industry’s impact on the power grid, electricity prices and the state’s climate goals.

The report lands as Sacramento lawmakers prepare a new round of data center legislation, following the collapse of similar proposals last year when the tech industry and business groups successfully blocked them in the Legislature.

“The costs that data centers impose on the electrical grid should be paid by the centers themselves, not by average California families already struggling with high utility bills,” said Pedro Nava, chair of the commission.

Scale of demand

At the center of the debate is the sheer scale of electricity demand anticipated from data centers. Pacific Gas & Electric, the state’s largest utility, told regulators that data center projects seeking power could add about 10 gigawatts of electricity demand over the next decade — roughly four times the generating capacity of the Diablo Canyon nuclear plant. For context, the Sacramento region uses a little over 3 gigawatts of electricity at its busiest times.

State energy planners assume many planned data center projects will never be built or will operate below full capacity. Companies can propose large data centers without committing to build them while AI computing and cooling requirements continue to evolve. But the commission’s report said California still needs a clearer picture of where that load will land.

The report recommends requiring confidential, facility-level reporting of data center electricity use so regulators can better forecast demand, identify where the grid has room for new projects and understand local reliability and environmental impacts.

Who pays for grid upgrades

Even a fraction of projected demand could require billions of dollars in new grid infrastructure, and consumer advocates warn the upgrades could shift costs onto households.

The report recommends a special electricity rate category for extremely large power users that would require prepayment for grid infrastructure, contributions toward wildfire safety costs and commitments to pay for a share of the power capacity they request.

“Data center growth has as much potential to increase electricity rates as it does to decrease rates if not done properly,” said Mark Toney, executive director of The Utility Reform Network.

Assemblymember Cottie Petrie Norris, a Democrat from Irvine who chairs the Assembly energy and utilities committee, said the commission’s findings align with pending legislation.

“The recommendations put forward by the Little Hoover Commission are one hundred percent aligned with the Assembly’s priorities,” Petrie Norris said. “We are moving expeditiously to pass a package of bills that will protect Californians from any rate increases and ensure that data centers pay their fair share.”

Environmental concerns

The commission’s report addressed environmental impacts alongside grid costs. Researchers say electricity use and carbon emissions from data center facilities have climbed sharply as AI expands.

The report warned that backup diesel generators at data centers add local air pollution concerns and that facilities can place significant demands on local water supplies. It recommends limiting pollution from backup generators, encouraging cleaner backup power and requiring better reporting so regulators can track the environmental footprint of large facilities.

Legislative outlook

Similar efforts in the previous legislative session — including proposals to require more transparency about energy use and to shield ratepayers from the cost of grid upgrades — stalled in the Legislature after opposition from the tech industry and business groups. The commission’s report does not have binding authority; its recommendations require action by the Legislature or state regulators to take effect.
