Debt Disclosure [Abstract] |
DEBT AND CREDIT FACILITIES | DEBT AND CREDIT FACILITIES The principal terms of our debt arrangements are described below and in Note 6 of the Notes to Consolidated Financial Statements in the Annual Report. SHORT-TERM DEBT Committed Lines of Credit At March 31, 2025, Sempra had an aggregate capacity of $9.9 billion under seven primary committed lines of credit, which provide liquidity and support our commercial paper programs. Because our commercial paper programs are supported by some of these lines of credit, we reflect the amount of commercial paper outstanding, before reductions of any unamortized discounts, and any letters of credit outstanding as a reduction to the available unused credit capacity in the following table.

Sempra, SDG&E and SoCalGas each must maintain a ratio of indebtedness to total capitalization (as defined in each of the applicable credit facilities) of no more than 65% at the end of each quarter. At March 31, 2025, each Registrant was in compliance with this ratio under its respective credit facility. The three lines of credit that are shared by SI Partners and IEnova require that SI Partners maintain a ratio of consolidated adjusted net indebtedness to consolidated earnings before interest, taxes, depreciation and amortization (as defined in each credit facility) of no more than 5.25 to 1.00 at the end of each quarter. At March 31, 2025, SI Partners was in compliance with this ratio. Uncommitted Line of Credit ECA LNG Phase 1 has an uncommitted line of credit with an aggregate capacity of $100 million that expires in August 2026. Borrowings are generally used for working capital requirements and can be in U.S. dollars or Mexican pesos. At March 31, 2025, ECA LNG Phase 1 had outstanding borrowings of $5 million, before reductions of any unamortized discounts, in Mexican pesos that bear interest at a variable rate based on the 28-day Interbank Equilibrium Interest Rate plus 154 bps. Borrowings made in U.S. dollars bear interest at a variable rate based on the one-month or three-month SOFR plus 164 bps and a credit adjustment spread of 10 bps. Uncommitted Letters of Credit Outside of our domestic and foreign credit facilities, we have bilateral unsecured standby letter of credit capacity with select lenders that is uncommitted and supported by reimbursement agreements. At March 31, 2025, we had $487 million in standby letters of credit outstanding under these agreements.

Term Loan In May 2024, SoCalGas entered into a $500 million, 364-day term loan facility with a maturity date of May 22, 2025, and in December 2024, SoCalGas increased the amount of the term loan to $700 million. SoCalGas borrowed the full $700 million available under the term loan, net of negligible debt issuance costs, which is included in Short-Term Debt on SoCalGas’ Balance Sheets. SoCalGas may request a further increase in the term loan facility of up to $300 million prior to the maturity date, subject to lender approval. The outstanding borrowings bear interest at a per annum rate equal to term SOFR, plus 80 bps and a credit adjustment spread of 10 bps. SoCalGas used the proceeds to repay commercial paper and for other general corporate purposes. Weighted-Average Interest Rates The weighted-average interest rates on all short-term debt were as follows:
WEIGHTED-AVERAGE INTEREST RATES |  |  |
| March 31, 2025 |  | December 31, 2024
Sempra | 5.02 | % |  | 5.03 | %
SDG&E | 4.73 |  |  | 4.76 |
SoCalGas | 5.11 |  |  | 5.02 |
LONG-TERM DEBT SDG&E In March 2025, SDG&E issued $850 million aggregate principal amount of 5.40% first mortgage bonds due in full upon maturity on April 15, 2035 and received proceeds of $840 million (net of debt discount, underwriting discounts and debt issuance costs of $10 million). The first mortgage bonds are redeemable prior to maturity, subject to their terms, and in certain circumstances subject to make-whole provisions. SDG&E intends to use the net proceeds for general corporate purposes, including repayment of outstanding commercial paper and potentially other indebtedness. Other Sempra ECA LNG Phase 1 ECA LNG Phase 1 has a five-year loan agreement with a syndicate of seven external lenders that matures on December 9, 2025 for an aggregate principal amount of up to $1.3 billion. IEnova and TotalEnergies SE have provided guarantees for repayment of the loans plus accrued and unpaid interest of 83.4% and 16.6%, respectively. At both March 31, 2025 and December 31, 2024, $1.1 billion of borrowings from external lenders were outstanding under the loan agreement, with a weighted-average interest rate of 7.36% and 7.29%, respectively. Proceeds from the loan are being used to finance the cost of construction of the ECA LNG Phase 1 project. Port Arthur LNG Port Arthur LNG has a seven-year term loan facility agreement with a syndicate of lenders that matures on March 20, 2030 for an aggregate principal amount of approximately $6.8 billion. At March 31, 2025 and December 31, 2024, $1.2 billion and $1.1 billion, respectively, of borrowings were outstanding under the loan agreement, both with an all-in weighted-average interest rate of 5.33%. In January 2025, Port Arthur LNG issued senior secured notes for an aggregate principal amount of $750 million and received proceeds of $742 million (net of debt issuance costs of $8 million). In April 2025, Port Arthur LNG issued senior secured notes for an aggregate principal amount of $250 million and received proceeds of $248 million (net of debt issuance costs of $2 million). The notes issued in January 2025 and April 2025 bear interest at the rate of 6.27% and 6.32%, respectively, and mature in December 2042. The net proceeds were used to repay borrowings and accrued interest under the existing Port Arthur LNG term loan facility.
