Sept 21 (Reuters) – California Governor Gavin Newsom on Monday signed seven bills aimed at regulating the fast-growing data center industry, imposing new requirements on electricity costs, water use and ​local oversight as communities push back against a surge ‌in AI-linked development.

• The legislation requires data centers to disclose information about electricity use, water consumption, land use and workforce needs, while giving local communities more information to assess proposed projects.

• The measures are designed to prevent the ‌cost ​of new power generation and grid upgrades ⁠needed for data centers ⁠from being shifted onto other ratepayers.

• “With these laws, we are ensuring that Californians remain in the driver’s seat — and that those profiting from data centers aren’t doing so at our expense,” ​Newsom said in a statement.bills

• California said the legislation will require data centers to comply with the state’s energy procurement requirements ⁠and help bring new clean-energy supplies ⁠onto the grid.

• The measures come amid growing concern ​nationwide over the impact of data centers on electricity demand, water ​resources and local infrastructure as technology companies race to expand ‌artificial intelligence capabilities.

• The rapid expansion of AI data centers has sparked resistance in California and elsewhere, with residents and advocacy groups raising concerns about electricity bills and pollution associated with the ⁠facilities.

• The Data Center Coalition, an industry trade group, said its members were committed to responsible development but warned the measures could push projects ⁠to other states: “Legislation ‌such as these create significant uncertainty and introduces ⁠potentially duplicative requirements that make doing business in ​California an ‌unattractive proposition for data centers and other industries,” ​Khara Boender, ⁠a director of government affairs for the group, said in a statement. “These are likely to further limit data center development in California — an already declining market—which pushes job creation, clean energy deployment, and tax revenue to neighboring states.”
