(Mayer Brown, Dec. 1, 2025) Seven bills signed Sept. 21, 2026, mostly effective Jan. 1, 2027: SB 886 and AB 2383 (CPUC data center tariffs so large loads bear their grid and supply costs), SB 1168 (rate-structure review), SB 887 (limits CEQA categorical exemptions for data centers), AB 2469 (water disclosure before local approval), AB 1577 and AB 2619 (energy and water reporting). (KQED, Sept. 21, 2026; The National Law Review (Greenberg Traurig), Oct. 5, 2026) Large-load tariff: PG&E Electric Rule 30 for transmission-level retail customers (CPUC A.24-11-007, filed Nov. 21, 2024); the CPUC partly granted interim use in July 2025, and the proceeding remained open in August 2026.
