, our General Mortgage Indenture and Deed of Trust dated as of November 1, 1992, as supplemented, modified and amended, and as it may be further amended and supplemented, including by the supplemental indenture dated as of February 1, 2025 establishing the specific terms of the bonds, which we refer to collectively as the mortgage indenture, between The Bank of New York Mellon Trust Company, N.A., as mortgage trustee, and us. The bonds offered by this prospectus supplement will be fungible with, will have the same CUSIP number as and will be consolidated and form a single series with, our 5.625% First Mortgage Bonds due 2055 issued on March 3, 2025, in the principal amount of $350 million. The bonds offered by this prospectus supplement will have identical terms (other than the date of original issuance, the offering price, the initial interest accrual date and the initial interest payment date) as the original bonds. Upon the issuance of the bonds offered by this prospectus supplement, the aggregate principal amount of outstanding 5.625% First Mortgage Bonds due 2055 will be $700,000,000. Unless the context otherwise requires, as used in this “Description of Bonds,” the term “bonds” means the original bonds together with the bonds offered by this prospectus supplement .

We may from time to time, without the consent of the existing holders of the bonds, “reopen” this series of bonds, which means we can create and issue further bonds having the same terms and conditions (including the same CUSIP number) as the series of bonds offered by this prospectus supplement in all respects, except for the date of original issuance, the offering price and, if applicable, the initial interest accrual date and the initial interest payment date . Any further bonds issued in this manner will be consolidated with, and form a single series with, the previously outstanding bonds of the same series.

The bonds will be represented by one or more global securities, in registered form, without coupons, and will be registered in the name of a nominee of The Depository Trust Company (“DTC”) . For so long as the bonds are registered in the name of DTC, or its nominee, we will pay the principal, premium, if any, and interest due on the bonds to DTC for payment to its participants for subsequent disbursement to the beneficial owners . See “— Global Securities and Book-Entry System” in this prospectus supplement.
