New rates would take effect **January 1, 2027**. The ERRA revenue requirement falls **3.3%** to $379.3 million, with a projected $45 million overcollection. The Portfolio Allocation Balancing Account rises **71%** to **$301.4 million**, partially offset by a prior-year balance reduction from $296.7 million to **$144.8 million**. Local Generation rises to **$285.4 million**, reflecting continued recovery of costs tied to Cost Allocation Mechanism-approved peakers, storage facilities, and microgrids. The various account shifts net $**12.9 million** above currently effective levels. Bundled customers see an approximate **1.2%** rate decline, aided by California Climate Credit returns; a typical 400 kWh residential customer sees no bill movement. Unbundled customers face a **1.4%** increase in delivery-plus-PCIA charges. For that audience, SDG&E's October update matters more than the May filing: Track 2 of R.25-02-005 [is still resolving pre-2019 REC valuation](https://docs.cpuc.ca.gov/PublishedDocs/Efile/G000/M606/K596/606596794.PDF?ref=calregulatory.com), and any Commission directive flows directly into PCIA rates when 2026 Market Price Benchmarks arrive in October. SDG&E forecasts **$181.4 million** in GHG allowance revenues: $137.8 million returned via California Climate Credits, $2.8 million to EITE customers. The filing also picks up the new Transmission Accelerator Revolving Fund obligation: **5%** of qualifying GHG auction revenues remitted to the state beginning **July 1, 2026**, due within 15 days of receipt. Below are illustrative rates. ![](https://storage.ghost.io/c/36/77/3677b301-4c92-43b7-8e2f-c7265d6b0b59/content/images/2026/05/bundled.png) ![](https://storage.ghost.io/c/36/77/3677b301-4c92-43b7-8e2f-c7265d6b0b59/content/images/2026/05/unbundled.png) *CRI's coverage of PG&E and SCE's 2027 ERRA Forecast filings is available* [*here*](https://www.calregulatory.com/2027-erra-forecasts-sce-procurement-costs-fall-yet-bills-edge-higher-pg-e-projects-5-7-bundled-increase/).

Because that decision addressed overlapping topics (including Renewable Thermal Certificate rules and biomethane interconnection costs), the ALJ is asking whether any findings, conclusions, or orders in D.26-04-044 affect positions parties have already taken in this proceeding. [Biomethane Cut, Hydrogen Denied, Transmission FinancingThe CPUC’s April 30 voting meeting featured major moves on biomethane, hydrogen, transmission, electric rates, and risk-based decision-making.![](https://storage.ghost.io/c/36/77/3677b301-4c92-43b7-8e2f-c7265d6b0b59/content/images/icon/Electromagnetic_radiation-1---1--3-affaf31a9d8ac42b10288a4198c5db3da6cd79e74a2eba105270a3207644de39.png)CALIFORNIA REGULATORY INTELLIGENCEMC![](https://storage.ghost.io/c/36/77/3677b301-4c92-43b7-8e2f-c7265d6b0b59/content/images/thumbnail/iterograph_Thu-Apr-30-2026--48--c09d52d4e7cc36cb9923deb9b6157ff57223c394fcbf43190abcd95cdee815f2.png)](https://www.calregulatory.com/april-30-cpuc-voting-meeting-results-biomethane-cut-hydrogen-denied-transmission-financing-opens/) - The second issue carries greater commercial significance for large gas users. The ruling again raises whether Energy Intensive Trade Exposed noncore customers should have a pathway to exemptions if Renewable Gas Standard above-market costs are ultimately allocated to noncore customers. The ALJ is seeking input on whether the CPUC should establish a process for developing such exemptions, what criteria should govern eligibility, and whether exemptions would be necessary to avoid emissions leakage. The issue first surfaced in a [February 5 supplemental ruling](https://docs.cpuc.ca.gov/PublishedDocs/Efile/G000/M598/K103/598103216.PDF?ref=calregulatory.com) and now returns for a more focused examination. Opening comments, capped at 10 pages, are due **June 3**. --- ### NATURAL GAS TRANSMISSION ASSETS Commissioner **Matthew Baker** issued a [scoping memo](https://docs.cpuc.ca.gov/PublishedDocs/Efile/G000/M606/K807/606807876.PDF?ref=calregulatory.com) in [A.25-12-014](https://docs.cpuc.ca.gov/PublishedDocs/Efile/G000/M591/K827/591827586.PDF?ref=calregulatory.com), setting the procedural roadmap for PG&E's proposed acquisition of full ownership of Standard Pacific Gas Line, currently owned six-sevenths by PG&E and one-seventh by Chevron. The transaction involves an asset sale to PG&E, related transportation agreements preserving Chevron's system access, and a 20-year stock purchase agreement for Chevron's remaining stake. --- ### LINE 225 UPDATE SoCalGas provided an [Envoy](https://www.socalgasenvoy.com/index.jsp?ref=calregulatory.com#nav=/Public/ViewExternal.showHome) update on the force-majeure event affecting Line 225 near the I-5 Freeway and Ridge Route Road in Castaic, indicating that geotechnical work has been completed and engineers have finalized the first phase of a repair plan for the damaged pipeline segment. Construction is expected to begin as early as **May 26** and continue for several months, though the timeline remains subject to change. In the meantime, SoCalGas advises customers to monitor the Envoy Capacity Utilization page for available pipeline capacity by scheduling cycle, a reminder that operational constraints tied to the outage remain relevant for shippers managing nominations and system flexibility.
