California passes new laws on AI data centers’ energy and water use
AI data centers in California now face stricter utility rules and must fund local infrastructure upgrades.
California Governor Gavin Newsom signed seven new laws that tighten regulation of AI data centers’ use of energy and water, aiming to prevent operators from shifting infrastructure costs onto residents. The package directs the California Public Utilities Commission to create a new rate class for data centers and requires them to pay for upgrades to local power and water systems. Proposed data centers must disclose projected water consumption, energy efficiency, and drought planning details to local governments. Facilities also need to meet defined energy, water, and fuel consumption thresholds to qualify for a streamlined approval track. These moves follow an executive order Newsom issued the prior week to accelerate work on an AI “kill switch.”
Why it matters
The new laws shift more of the cost and risk of AI data center expansion from residents to operators. Data center developers will have to pay for local power and water system upgrades, meet specific resource-use thresholds to access a faster approval track, and disclose projected water use, efficiency, and drought plans to local governments. The package is part of a broader push that includes work on an AI “kill switch,” and is meant to ensure local communities see benefits rather than higher bills or strained utilities.
