Governor Gavin Newsom signed seven data center bills into law on September 21, the most sweeping state-level package yet on the industry’s power, water, and land-use footprint. Three of the bills carry the electricity provisions: SB 1168 directs the California Public Utilities Commission to build new rate structures specifically for data centers; SB 886 creates the California Technology Innovation and Ratepayer Protection Act; AB 2383 governs electricity service to data centers directly. The throughline is cost allocation — grid upgrades triggered by a data center’s load now land on that data center, not on ratepayers broadly.
“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 the signing announcement, framing the package explicitly against the Trump administration’s deregulatory posture on the sector.

None of the seven bills define the threshold that triggers these obligations. No megawatt figure, no dollar amount, no reporting cadence. SB 1168 hands that work to the CPUC, which has to open a rulemaking proceeding and write the actual numbers before any operator owes a specific figure. Four companion bills — AB 1577, AB 2469, AB 2619, and SB 887 layer on water-use disclosure requirements and strip data centers of the blanket CEQA environmental exemption they previously held.
California is now the third U.S. jurisdiction to shift data center infrastructure costs onto operators this month, following a 417-3 House vote and a Texas deposit-structure change — a pattern, not an outlier. The state hosts 296 data centers, third-most in the country.
Bottom line: The interconnection queue itself hasn’t changed — a project that pays its upgrade bill and files its water numbers still moves forward. What’s changed is the certainty gap: any operator underwriting a California campus for 2027 now has a statutory obligation with no dollar figure attached to it, and a CPUC proceeding on the calendar whose outcome nobody has seen yet.
