- California Gov. Gavin Newsom on Monday signed seven bills requiring data centers to pay their fair share of grid upgrade costs, disclose water use to local governments, and give up eligibility for blanket environmental exemptions, per the governor's office.
- SB 1168, sponsored by state Sen. Jerry McNerney, directs the California Public Utilities Commission to examine data centers' energy use and ensure they pay for transmission and distribution upgrades and load increases; McNerney warned that rapid data center growth could push already-high California utility bills "through the roof."
- SB 886 and SB 887, sponsored by state Sen. Steve Padilla, require data centers to pay all infrastructure upgrade and generation costs, bear a larger share of wildfire mitigation and liability costs, and undergo environmental review — what Padilla called "some of the nation's strongest data center ratepayer protections."
- AB 1577 mandates monthly reporting of data centers' energy consumption and efficiency metrics to the California Energy Commission, plus disclosure of estimated energy usage to local agencies during the permitting process.
- AB 2383, sponsored by Assemblyman Rick Chavez Zbur, incentivizes data centers to use onsite clean energy resources to keep electricity costs down for consumers.
- AB 2469 and AB 2619, sponsored by Assemblymember Diane Papan, require data center developers to complete a water supply assessment and water scarcity plan during permitting and establish a statewide water reporting requirement tied to business license issuance and renewal.
- The new laws follow Los Angeles County's planning director ordering a temporary ban on large-scale AI data centers in unincorporated areas; California is home to 296 data centers, the third-highest count in the U.S. according to Data Center Map.
Why it matters: Data center operators in California — home to 296 facilities, the third-highest U.S. count — now face mandatory grid cost-sharing, monthly energy reporting to the California Energy Commission, and water assessment requirements during permitting. Local agencies gain new tools to evaluate projects before they break ground, shifting financial responsibility for infrastructure upgrades and wildfire mitigation from ratepayers to operators.
