Item 8.01 Other Events.
2024 General Rate Case of San Diego Gas & Electric Company and Southern California Gas Company
On December 19, 2024, the California Public Utilities Commission (CPUC) approved a final decision (FD) in the 2024 General Rate Case (GRC) of San Diego Gas & Electric Company (SDG&E) and Southern California Gas Company (SoCalGas). SDG&E and SoCalGas are subsidiaries of Sempra. The GRC FD authorizes SDG&E’s and SoCalGas’ test year revenue requirements for 2024 and attrition year adjustments for 2025 through 2027, inclusively. In addition, the GRC FD provides SDG&E and SoCalGas with numerous mechanisms to seek cost recovery of additional projects and programs as described below.
2024 Revenue Requirements and Attrition Year Revenues
The GRC FD adopts a test year 2024 revenue requirement of $2,699 million for SDG&E’s combined operations ($2,193 million for its electric operations and $506 million for its natural gas operations). SDG&E’s authorized 2024 combined revenue requirement represents an increase of $189 million (7.5%) over its authorized 2023 combined revenue requirement. In connection with SDG&E’s election to change its tax accounting method for gas repairs expenditures, the 2024 revenue requirement increase is net of $68 million of total estimated income tax benefits for 2023 and 2024 to be flowed through to customers in the 2024 test year as a pass-through benefit. The GRC FD also specifies an increase in SDG&E’s 2025, 2026, and 2027 combined revenue requirements of $147 million (5.45%), $119 million (4.17%) and $122 million (4.11%), respectively, over the preceding year’s combined revenue requirement. The 2025, 2026 and 2027 revenue requirements will be updated to implement a previously authorized change in the cost of capital that adjusted SDG&E’s rate of return to 7.45%.
The GRC FD adopts a test year 2024 revenue requirement of $3,806 million for SoCalGas. SoCalGas’ authorized 2024 revenue requirement represents an increase of $324 million (9.3%) over its authorized 2023 revenue requirement. In connection with SoCalGas’ election to change its tax accounting method for gas repairs expenditures, the 2024 revenue requirement increase is net of $202 million of total estimated income tax benefits for 2023 and 2024 to be flowed through to customers in the 2024 test year as a pass-through benefit. The GRC FD also specifies an increase in SoCalGas’ 2025, 2026, and 2027 revenue requirements of $190 million (5.00%), $116 million (2.91%) and $120 million (2.92%), respectively, over the preceding year’s revenue requirement. The 2025, 2026 and 2027 revenue requirements will be updated to implement a previously authorized change in the cost of capital that adjusted SoCalGas’ rate of return to 7.49%.
Existing and Anticipated Requests for Recovery of Specified Safety, Maintenance and Reliability Investments
The GRC provides SDG&E and SoCalGas with numerous mechanisms to seek cost recovery of specified projects and programs. We expect that the requests for cost recovery of these projects and programs, which remain subject to CPUC approval, will result in additional amounts of authorized revenue requirement that are not included in the amounts described above. The referenced projects and programs and their cost recovery mechanisms are as follows:
GRC Track 2 and Track 3 Requests for Wildfire Mitigation Plan and Pipeline Safety Enhancement Plan Costs. Although SDG&E’s Track 2 request for review and recovery of wildfire mitigation plan costs incurred from 2019 through 2022, inclusively, is not addressed in the GRC FD, SDG&E anticipates receiving a decision on this request in the first half of 2025. SDG&E also expects to file a Track 3 request in the first half of 2025 for review and recovery of wildfire mitigation plan costs incurred in 2023. The GRC FD expanded the scope of the Track 3 filing to include review of SoCalGas’ and SDG&E’s Pipeline Safety Enhancement Plan costs incurred from 2015 to 2020, inclusively.
Advice Letter Filings to Implement Additional Revenue Requirements for Certain Capital Projects. Subject to applicable cost caps, the GRC FD approved SDG&E’s Moreno compressor station project and SoCalGas’s Honor Rancho compressor station and customer information system replacement projects. Upon completion of these projects, SDG&E and SoCalGas intend to file advice letters to implement the revenue requirements associated with each project’s respective costs. The referenced advice letters are subject to CPUC approval.
Applications to Seek Cost Recovery of Specified Projects and Programs. The GRC FD also provides SDG&E and SoCalGas the opportunity to file separate applications for cost recovery of their mobile home park and gas integrity management programs, among others, and advanced metering infrastructure replacements at SDG&E. These applications will be subject to reasonableness reviews of the work performed and associated costs and will be subject to CPUC approval.
Accounting Impacts
SDG&E and SoCalGas recorded revenues in the first nine months of 2024 based on levels authorized for 2023 because a final decision in the GRC was not issued by September 30, 2024. Since the GRC FD is effective retroactive to January 1, 2024, SDG&E and SoCalGas will record the retroactive impacts in the fourth quarter of 2024.

Additional information regarding the GRC is provided in Note 4 of the Notes to Consolidated Financial Statements in the combined Annual Report on Form 10-K for the year ended December 31, 2023 for Sempra, SDG&E and SoCalGas, and in Note 4 of the Notes to Condensed Consolidated Financial Statements in the combined Quarterly Report on Form 10-Q for the quarter ended September 30, 2024 for Sempra, SDG&E and SoCalGas.
Federal Energy Regulatory Commission (FERC) Rate Matters
SDG&E files separately with the FERC for its authorized return on equity (ROE) on FERC-regulated electric transmission operations and assets.
FERC Transmission Owner Formula Rate 5 (TO5)
In October 2019, SDG&E reached a settlement with parties in SDG&E’s TO5 proceeding. The settlement provides for a ROE of 10.60%, consisting of a base ROE of 10.10% plus an additional 0.50% ROE for participation in the California Independent System Operator (the California ISO adder). The settlement further provides that SDG&E will refund the California ISO adder as of June 1, 2019 if the FERC issues an order ruling that California investor-owned utilities are no longer eligible for the California ISO adder.
In December 2024, the FERC issued an order finding that SDG&E is not eligible for the California ISO adder. As a result of the FERC order, Sempra and SDG&E will record a charge of approximately $120 million ($89 million after tax) on the Sempra and SDG&E Consolidated Statements of Operations, respectively, prepared in conformity with generally accepted accounting principles (GAAP) in the fourth quarter of 2024, all of which will be an adjustment to Sempra’s 2024 non-GAAP earnings calculations.
SDG&E believes there is a reasonable basis to appeal the FERC order and intends to do so in the first quarter of 2025.
FERC Transmission Owner Formula Rate 6 (TO6)
In October 2024, SDG&E submitted its TO6 filing to the FERC, requested to be effective January 1, 2025 and subject to refund. SDG&E’s TO6 filing proposes, among other items, an increase to SDG&E’s currently authorized base ROE from 10.10% to 11.75%, plus the California ISO adder, for a total of 12.25%.
Aliso Canyon Senate Bill (SB) 380 Order Instituting Investigation
In February 2017, the CPUC opened the Aliso Canyon proceeding SB 380 Order Instituting Investigation (OII) to determine the feasibility of minimizing or eliminating the use of the Aliso Canyon natural gas storage facility (Aliso Canyon) while still maintaining energy and electric reliability for the region, including analyzing alternative means for meeting or avoiding the demand for the facility’s services if it were eliminated.
In August 2023, the CPUC issued a decision to increase the interim range of gas inventory levels at Aliso Canyon from 41.6 billion cubic feet (bcf) to 68.6 bcf.
On December 19, 2024, the CPUC approved a final decision in the SB 380 OII finding that Aliso Canyon is necessary for natural gas and electric reliability and affordable rates and closed the OII. Among other things, and subject to future CPUC biennial reviews and potential additional proceedings, the final decision authorizes Aliso Canyon to continue operating and sets the maximum working natural gas storage level at 68.6 bcf.
