California Makes Data Centers Disclose Water and Power Costs

California Gov. Gavin Newsom signed seven laws on September 21 requiring data centers to disclose water and electricity demands, pay for certain infrastructure upgrades and face tighter local review. The package directly challenges the industry’s argument that communities should approve large computing facilities first and address their costs later.
Newsom’s administration presented the measures as a response to rising electricity demand, grid constraints, water consumption and pollution linked to data-center growth. Supporters say the laws protect residents from paying for facilities built to serve some of the world’s largest technology companies. Developers and their allies have argued that California needs to preserve room for digital infrastructure and economic growth.
“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.” — Gavin Newsom, Governor of California
Seven bills put water and electricity on the record
The legislation covers reporting, utility costs, water planning and environmental review. Assembly Bill 1577 requires data-center reporting, while Assembly Bill 2383 addresses electricity use. Assembly Bill 2469 establishes water-use disclosures, and Assembly Bill 2619 addresses data centers’ effect on water resources.
Senate Bill 886, authored by Sen. Steve Padilla and Sen. Jerry McNerney, is titled the California Technology Innovation and Ratepayer Protection Act. Senate Bill 887 concerns environmental review for data centers and geothermal power projects. Senate Bill 1168 establishes data-center rate structures.
The package does not ban data centers or impose a statewide moratorium. Instead, it sets conditions intended to make the facilities’ resource demands visible before local and state decisions are made.
Developers must account for grid upgrades
Under the new laws, data centers must comply with California energy procurement requirements, bring new clean-energy supply onto the grid where required and pay for upgrades tied to their projects. The state says the measures are designed to prevent data centers from shifting those costs to ordinary electricity customers, including low-income households.
Water disclosures arrive after a year of pushback
Proposed data centers will have to provide local governments and water suppliers with information about expected water use, available supply, efficiency measures and drought planning. If a project requires water-system upgrades, the data center must pay for them.
California’s action focuses on disclosure and cost allocation rather than a single limit on water consumption. That distinction leaves local governments with more information but does not guarantee that every proposed facility will be rejected when its resource demands are high.
Environmental review becomes harder to bypass
The laws also restrict blanket environmental exemptions for data centers. Before a project can receive judicial streamlining, it must demonstrate that it will not shift costs to ratepayers and that it meets state standards for energy, water and fuel consumption.
That provision gives communities a stronger role in reviewing projects that could affect local air quality, water systems, land use and electricity reliability. It also places the burden on developers to document how a facility will operate rather than leaving residents to assemble that information after approval.
Newsom signed the measures as the expansion of AI computing increases demand for large, power-intensive facilities. California’s new framework does not settle where those facilities should be built, but it establishes what developers must disclose and which costs they must carry before construction moves ahead.
