CALIFORNIA PUBLIC UTILITIES COMMISSION (CPUC or COMMISSION)[1]

Proposed Decisions and Resolutions

Rulemaking (R.) 18-07-003 (Order Instituting Rulemaking to Continue Implementation and Administration, and Consider Further Development, of California Renewables Portfolio Standard Program)

This decision denies the March 6, 2025 petition to modify Decision (D.) 20-08-043, filed by the Bioenergy Association of California, seeking to extend or remove the end date of the Bioenergy Market Adjusting Tariff (BioMAT) and proposing other programmatic changes, primarily due to underutilization of this high-cost program and availability of other procurement options for bioenergy resources. The decision maintains the BioMAT end date, December 31, 2025, as directed by the Commission in D.20-08-043, which the Commission reasons is in alignment with the October 30, 2024 Governor’s Executive Order N-5-24 on affordability, and will allow Commission resources to be directed toward more effective clean energy programs.

Application (A).22-02-014 (In the Matter of the Application of Southern California Edison Company for a Permit to Construct Electrical Facilities with Voltages Between 50 kV and 200 kV: Gorman-Kern River Project)

This decision grants Southern California Edison Company’s request for a permit to construct the proposed Transmission Line Rating Remediation Gorman-Kern River 66 kilovolt Project.

Voting Meeting

The CPUC held a voting meeting in San Francisco, California on September 18, 2025, at 11:00 a.m. PT.  The results for the energy-related items on the agenda are below:

Item 2. Res G-3605 (SoCalGas’s 2024 Compliance Plan, Forecasts, and Caps for Its Natural Gas Leak Abatement Program)

This Resolution approves in part and denies in part SoCalGas’s 2024 Natural Gas Leak Abatement (NGLA) Compliance Plan and the ratemaking forecasts as presented in AL 6277-G-B.  SoCalGas requested a forecasted total revenue requirement of $483.12 million.  This Resolution approves $102 million for Blowdown Reduction Activities, as it is the sole cost-effective measure in the program.  All other costs for Best Practices and Research Development & Demonstration are denied.  An additional $4.245 million for SoCalGas’s NGLA Program Administration is authorized for recording in the NGLA Program Memorandum Account for potential recovery in a future GRC or other proceeding, where it will be subject to a reasonableness review.  The Resolution approves $78.8 million for ongoing capital undercollections from previously approved Compliance Plans.  Approved.

Item 3. Resolution (Res) G-3606 (SDG&E 2024 NGLA Ratemaking Forecasts and Capital Costs Recovery)

This Resolution denies SDG&E’s 2024 NGLA ratemaking forecasts as presented in AL 3285-G-A for costs for its 2024 Compliance Plan.  SDG&E forecasts a total revenue requirement of $24.859 million in AL 3285-G-A: $22.919 million for Best Practices; $1.29 million for Research, Development, and Demonstration (RD&D) projects; $0.428 million for Program Administration; and $0.222 million for any under-recovered ongoing capital revenue requirements.  This Resolution approves no funding for Best Practices because none of the practices is cost-effective.  Costs for RD&D are also denied.  SDG&E is authorized to record up to $0.428 million for NGLA Program Administration, if applicable, in the NGLA Program Memorandum Account for potential recovery in a future GRC or other proceeding, where it will be subject to a reasonableness review.  The Resolution approves $222,000 for unrecovered ongoing capital costs from previously approved Compliance Plans.  Held to October 9, 2025.

Item 8. Res ALJ-482 (Appeal by Silicon Valley Clean Energy Authority of Citation No. E-4195-0143)

This Resolution resolves Silicon Valley Clean Energy Authority’s appeal of Citation No. E-4195-0143 issued by the Commission’s Consumer Protection and Enforcement Division. Citation No. E-4195-0143 cites and fines Silicon Valley Clean Energy Authority for failing to procure certain of its June, July, August, and September 2023 Year-Ahead System RA requirements and for failing to file its Year-Ahead System RA compliance filing at the time and in the manner required. This Resolution denies the appeal.  Approved.

Item 10. Application (A.) 23-01-008 (Application of SDG&E for Authority to Update Marginal Costs, Cost Allocation, and Electric Rate Design)

This decision addresses the 2024 GRC Phase 2 proceeding of SDG&E. This decision adopts three settlement agreements: (1) the Partial Settlement Agreement, which resolves cost allocation, creation of a Medium Commercial Class, base time-of-use rates, and most of the other contested issues in this proceeding; (2) the Marginal Cost Settlement Agreement that includes proposals to set marginal costs used in cost allocation and rate design; and (3) the Medical Baseline Settlement Agreement that provides for a line-item medical baseline discount. This decision also adopts the system percentage of change methodology to update rates, resolves other bill presentment issues that were raised by parties, and approves SDG&E’s other uncontested proposals.  Signed, D.25-09-006.

Item 11. Rulemaking (R.) 20-05-003 (Order Instituting Rulemaking to Continue Electric Integrated Resource Planning and Related Procurement Processes)

This decision grants, with modifications, the petition for modification (PFM) of D.23-02-040 and D.24-02-047 filed by Southern California Edison Company (SCE), seeking a waiver of the requirements for bridge contracts for resources required by D.21-06-035 and D.23-02-040, for the months not including July, August, and September of each year. SCE’s PFM argues that there is no short-term reliability needed for these bridge resources during the lower-demand months, and that load-serving entities (LSEs) that have met their month-ahead system RA requirements should not be required to procure additional bridge resources not needed for short-term reliability. According to the proposed decision, this decision goes beyond the relief requested by SCE and eliminates the option for LSEs to use bridge contracts as an alternative compliance mechanism for the long-term procurement requirements of D.21-06-035 and D.23-02-040 for all months of the year, relieving ratepayers of the additional costs of those bridge resources that do not provide significant short-term reliability benefits. The decision determines that, for the purposes of satisfying procurement obligations in D.21-06-035 and D.23-02-040, the RA month-ahead requirements should provide sufficient incentive to procure the same types of resources included in most bridge contracts, if such contracts prove necessary for short-term reliability purposes.  Signed, D.25-09-007. 

Item 25. R.25-09-004 (Order Instituting Rulemaking to Enhance Demand Response in California)

This Order Instituting Rulemaking seeks to evaluate and enhance the consistency, predictability, reliability, and cost-effectiveness of demand response resources. The rulemaking will update the demand response guiding principles, policies, and data system and process requirements.  Signed, R.25-09-004.

Item 26. A.24-09-001 (Application of Southwest Gas Corporation for Authority to Increase Rates and Charges for Gas Service in California, Effective January 1, 2026)

This interim decision grants the motion filed by Southwest Gas Corporation to establish a GRC Memorandum Account to track changes in its revenue requirement for the period beginning January 1, 2026, through the effective date of the Commission’s final decision regarding Southwest Gas’s revenue requirement increase request through A.24-09-001, if the decision is issued after January 1, 2026. Signed, D.25-09-017.

Item 27. A.12-05-020 (In the Matter of Application of SDG&E for a Certificate of Public Convenience and Necessity for the South Orange County Reliability Enhancement Project)

This decision grants SDG&E’s PFM of D.16-12-064 to increase the $381 million cost cap established by that decision and adopts $410 million as the increased reasonable and prudent maximum cost cap for the South Orange County Reliability Enhancement Project. Held to October 9, 2025.

Item 43. A.23-05-010 (SCE 2025 Test Year GRC Application)

The decision approves a test year base revenue requirement of $9.756 billion for SCE for 2025-2028.  The adopted amount is a 13.68 percent increase over SCE’s current authorized revenue requirement compared to SCE’s requested 22.15 percent increase.  This decision also authorizes post-test year revenue requirement adjustments of $453 million for 2026 (a 4.64 percent increase), $411 million for 2027 (a 4.03 percent increase), and $374 million for 2028 (a 3.52 percent increase), along with the adoption of a post-test year ratemaking mechanism.  SCE requested approximately $5.104 billion in capital expenditures for wildfire mitigation from 2025 to 2028, and the decision approves approximately $3.085 billion of total capital expenditures for wildfire mitigation.  SCE is directed to implement the 2025 test year revenue requirement in rates beginning October 1, 2025, or as soon thereafter as it may be affected.  The incremental revenue increase that has accrued from January 1, 2025, through September 30, 2025, will be amortized over a 24-month period.  Signed, D.25-09-030.

CALIFORNIA AIR RESOURCES BOARD (CARB)

Climate Risk Disclosure Laws Update

CARB announced it will be issuing proposed rules for the state’s climate risk disclosure laws, Senate Bills (SB) 253 and 261, on October 14, 2025.  CARB also issued a projected cost of compliance for the laws and shared the disclosure timeline for companies covered by SB 253 to disclose their scope 1 and scope 2 emissions for the first time.  Companies covered by SB 253 should expect to report their scope 1 and scope 2 emissions by June 30, 2026.

CARB also released draft guidance on September 2 to assist reporting entities in complying with the Climate Related Financial Risk Disclosure Program.

Meetings and Workshops

 On September 25, 2025, CARB will conduct a public hearing to consider proposed amendments to the Advanced Clean Fleets (ACF) and the Low Carbon Fuel Standard (LCFS) regulations.  According to CARB, the proposed amendments would provide more flexibility to public agency utilities subject to the state and local government requirements of the ACF regulation.  This rulemaking also would repeal California Code of Regulations, title 13, sections 2014 and 2015, which contain the drayage and high priority and federal fleet requirements of the ACF regulation.  In January 2025, CARB withdrew its request for a waiver and authorization for the addition of the ACF regulation to California’s emissions control program, foreseeing that the waiver request to the U.S. Environmental Protection Agency would not be granted.  The proposed amendments will also amend the LCFS regulation set forth in California Code of Regulations, title 17, section 95486.3, to provide stronger credit support for hydrogen stations.

On October 14, 2025, CARB will host a virtual public workshop to discuss introducing gasoline containing up to 15 percent ethanol (E15) in California. California gasoline is currently blended with up to 10 percent ethanol by volume (E10), the maximum ethanol content allowed by the California Reformulated Gasoline Regulations. At this workshop, CARB staff will provide an overview of the scientific evaluation of E15, current regulatory requirements, and concepts for potential regulatory updates as well as additional topics regarding the use of E15 in California. Staff will seek stakeholder input through verbal feedback during the workshop and will open a public docket for written comments. That public docket will be open for four weeks following the workshop through November 11, 2025.

Public Notice and Comment Period for Proposed Emergency Amendment and Adoption of Vehicle Emissions Regulations

CARB proposes to adopt emergency vehicle emissions regulations (the Emergency Vehicle Emissions Regulation) that will amend California Code of Regulations, titles 13 and 17, and adopt new sections into California Code of Regulations, titles 13 and 17. The amendments would confirm that, until a court resolves the uncertainty created by the federal government’s actions, certain antecedent regulations (displaced by Advanced Clean Cars (ACC) II and Omnibus) remain operative. CARB staff is proposing to amend its regulations to clarify that the criteria pollution provisions of the LEV III regulation (adopted as part of ACC I) and associated on-board diagnostic requirements remain operative, with the caveat that CARB may enforce the more recently adopted LEV IV requirements (adopted as part of ACC II) to the extent permitted by law, in the event a court of law holds invalid the resolution purporting to disapprove that waiver.

CARB submitted the Emergency Amendment and Adoption of Vehicle Emissions Regulations to the Office of Administrative Law (OAL) on September 22, 2025. The submitted action appears on the list of “Emergency Regulations Under Review” on OAL’s website at: https://oal.ca.gov/emergency_regulations/Emergency‌_Regulations_Under_Review/.

Emergency rulemakings have a five-calendar-day comment period that begins when OAL posts the notice of the pending emergency action on the OAL website.

MINNESOTA PUBLIC UTILITIES COMMISSION (MPUC)

At its September 25, 2025 agenda meeting, the MPUC will hear oral arguments regarding the ALLETE acquisition proceeding, involving the proposed acquisition of ALLETE and its operating division, Minnesota Power, by Canada Pension Plan Investment Board and Global Infrastructure Partners (collectively, the “Petitioner”). At the hearing, the MPUC will consider whether the proposed acquisition is consistent with the public interest, whether the proposed settlement filed jointly by the Department of Commerce and Petitioners comports with the public interest, and whether to approve the proposed acquisition. Following oral arguments, the MPUC will hold deliberations on October 3, 2025, wherein it will decide whether to approve the acquisition.

OREGON PUBLIC UTILITIES COMMISSION (OPUC)

At its September 30, 2025, agenda meeting, the OPUC will hold a public hearing and commissioner work session related to (1) PacifiCorp’s 2026-28 Transportation Electrification Plan (UM 2056), and (2) the proposed carveout capacity expansion associated with community solar implementation through the Oregon Community Solar Program (UM 1930). The agenda is here. Additionally, on August 29, 2025, PacifiCorp and Portland General Electric were issued FERC orders accepting their open access transmission tariff revisions to enable participation in CAISO’s extended day-ahead market.

WASHINGTON UTILITIES AND TRANSPORTATION COMMISSION (WUTC)

At its September 25, 2025 agenda meeting, the WUTC will consider the petitions for an order authorizing deferred accounting treatment for the cost of tariffs imposed on natural gas imported from Canada of Avista Corporation (UE-250132), Puget Sound Energy (PSE) (UE-250135), and Cascade Natural Gas Company (UG-250151); PSE’s Annual Power Cost Adjustment Mechanism filing, wherein it requests approval for a net power cost revenue requirement increase of $26.8 million (0.8 percent), recovered over 15 months beginning on October 1, 2025, which it anticipates will increase many residential ratepayers’ monthly bills by 0.5 percent (UE-250318); PacifiCorp’s filing to revise its Tariff WN U-76 to establish Schedule 138 – Net Billing Service, to facilitate the transition from Net Metering to Net Billing (UE-250695); Northwest Natural Gas Company’s Conservation Potential Assessment for the 2026-2027 biennium (UG-250429); and Basin Water Sources, Inc.’s Tariff filing to impose a surcharge of $7.59 per month (not to exceed $64,500) to reimburse the Company for expenses incurred for an engineering assessment of the water system (UW-250570). The agenda is here.

Federal Agencies

FEDERAL ENERGY REGULATORY COMMISSION (FERC)

Commissioner Nominations

Laura Swett and David LaCerte continue to await their Senate confirmation hearings for their FERC Commissioner nominations following their advancement from the U.S. Senate Energy and Natural Resources Committee.

Meetings and Conferences

On September 18, 2025, FERC held its September Commission Meeting. Among other items, FERC:

• Approved a set of actions to address grid reliability, including directing North American Electric Reliability Corporation (NERC) to address supply chain risks in new or modified reliability standards, proposing to add and modify definitions and standards to improve virtualization, proposing to add new security requirements for communications and system management in a revised reliability standard, and approving NERC revisions to a reliability standard addressing extreme cold weather;
• Directed Southwest Power Pool (SPP) to make a compliance filing related to its proposed refund plan to unwind certain credit payment obligations for service taken from 2008 to 2016 under Attachment Z2 of SPP’s tariff; and
• Addressed requests for rehearing of the FERCs’ February 6, 2024 order rejecting with guidance Pennsylvania New Jersey Maryland Interconnection’s (PJM) proposed changes to market seller offer cap, capacity performance, and energy and ancillary services rules. FERC’s order upholds the prior rejection but sets aside previous guidance addressing PJM’s alternative offer cap proposal and allows PJM to make additional proposals in future filings.

Additional summaries of the orders voted by FERC at its September meeting are available here.

FERC noticed a technical conference on October 21, 2025, to discuss cost-effective ways to reduce the risk of wildfire ignition from the bulk power system. FERC has directed NERC to prepare a report on the best practices to reduce these risks and to assess the need for new or revised reliability standards. NERC, in its report, must assess vegetation management, the removal of forest-hazardous fuels by transmission lines, engineering, and operational practices.
