SCE rate timeline: what the 2025 GRC means for 2026–2028 bills

A plain-language map of CPUC Decision 25-09-030, post-test-year revenue steps, and how climate credits interact with the base rate path for Southern California Edison customers.

Editor’s note: Revenue requirement is not the same as your monthly bill. Balancing accounts, generation costs, wildfire charges, and climate credits move bills separately from the GRC base.

Southern California Edison’s current multi-year rate framework comes from the California Public Utilities Commission’s Decision 25-09-030, issued Sep 18, 2025, in Application A.23-05-010—the utility’s Test Year 2025 General Rate Case.

The decision authorized a 2025 test-year base revenue requirement of $9.664 billion, with estimated post-test-year base revenue increases of $544 million in 2026, $522 million in 2027, and $447 million in 2028.

Separately, SCE announced in August 2026 that residential customers would receive two automatic $36 California Climate Credits during August and September ($72 combined), timed by the CPUC for high-use summer months.

Practical takeaway: watch the GRC base path, wildfire liability politics that can move financing costs, and credits or true-ups that appear as line items.
