Exhibit 10.1

Execution Version

AMENDMENT NO. 3 and Consent, dated as of March 16, 2026 (this “Agreement”), among DUKE ENERGY CORPORATION (the “Company”), DUKE ENERGY CAROLINAS, LLC (“Duke Energy Carolinas”), DUKE ENERGY OHIO, INC. (“Duke Energy Ohio”), DUKE ENERGY INDIANA, LLC (“Duke Energy Indiana”), DUKE ENERGY KENTUCKY, INC. (“Duke Energy Kentucky”), DUKE ENERGY PROGRESS, LLC (f/k/a PROGRESS ENERGY CAROLINAS, INC.) (“Duke Energy Progress”), DUKE ENERGY FLORIDA, LLC (f/k/a PROGRESS ENERGY FLORIDA, INC.) (“Duke Energy Florida”) and PIEDMONT NATURAL GAS COMPANY, INC. (“Piedmont”), the LENDERS party hereto (the “Lenders”), the ISSUING LENDERS party hereto (the “Issuing Lenders”), WELLS FARGO BANK, NATIONAL ASSOCIATION, as Administrative Agent and Swingline Lender.

A.           Reference is made to the Amended and Restated Credit Agreement dated as of March 18, 2022 (as amended, modified or supplemented from time to time prior to the date hereof, the “Existing Credit Agreement”), among the Company, Duke Energy Carolinas, Duke Energy Ohio, Duke Energy Indiana, Duke Energy Kentucky, Duke Energy Progress, Duke Energy Florida and Piedmont (the “Borrowers”), the Lenders party thereto and Wells Fargo Bank, National Association, as administrative agent for the Lenders (in such capacity, the “Administrative Agent”) and as swingline lender (in such capacity, the “Swingline Lender”).

B.           The Borrowers intend to exercise one of the two remaining extension options available pursuant to Section 2.01(b) of the Existing Credit Agreement to extend the Commitment Termination Date for one year, and each Lender executing this Agreement as an “Extending Lender” (each, an “Extending Lender”) has approved such request pursuant to Section 2.01(b) of the Existing Credit Agreement.

C.           The Borrowers further request that the Lenders make certain amendments to the Existing Credit Agreement on the terms and conditions set forth herein, and each Lender executing this Agreement as an “Amending Lender” (each, an “Amending Lender”) has approved such amendments.

Accordingly, in consideration of the mutual agreements herein contained and for other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Terms Generally. (a)  The rules of construction set forth in Section 1.01 of the Existing Credit Agreement shall apply mutatis mutandis to this Agreement. Capitalized terms used but not defined herein have the meanings assigned thereto in the Existing Credit Agreement.

(b)  As used in this Agreement, “Third Amendment Effective Date” shall have the meaning assigned to such term in Section 5.

SECTION 2. Extension. Pursuant to Section 2.01(b) of the Existing Credit Agreement, the Borrowers have requested an extension of the Commitment Termination Date for a period of one year from March 16, 2030 to March 16, 2031 (the “Extension”). As of the date hereof, Extending Lenders holding Commitments in an aggregate amount equal to at least 51% of the Commitments currently in effect have agreed to extend (such agreement evidenced by their execution of this Agreement as an Extending Lender) the Commitment Termination Date as to the Extending Lenders for a period of one year from March 16, 2030, to March 16, 2031. Subject to the satisfaction of the conditions in Section 5 hereof, the Commitment Termination Date as to the Extending Lenders is hereby extended to March 16, 2031. The Commitment Termination Date as to each non-extending Lender remains unchanged, subject to the right of the Borrowers pursuant to Section 2.01(b) of the Existing Credit Agreement to designate another bank or other financial institution (which may be, but need not be, an Extending Lender) to replace a non-consenting Lender. The Extending Lenders (constituting the Required Lenders) hereby waive any timing, notice or other similar requirement pursuant to Section 2.01(b) of the Existing Credit Agreement required in connection with the Extension. The Extension as set forth in this Section 2 shall be deemed to constitute an exercise of the Borrower’s right to request an extension of the Commitment Termination Date pursuant to Section 2.01(b) of the Existing Credit Agreement and the effective date of such Extension shall be deemed to be the Extension Date; provided that, notwithstanding anything to the contrary in Section 2.01(b) of the Existing Credit Agreement, two additional one-year extensions shall be permitted pursuant to Section 2.01(b) of the Credit Agreement after the Extension Date.

SECTION 3. Amendments to the Existing Credit Agreement.

(a)  Section 1.01 of the Existing Credit Agreement is hereby amended to delete the definition of “Adjusted Term SOFR” and “SOFR Adjustment”.

(c)  The definition of “Internal Revenue Code” in Section 1.01 of the Existing Credit Agreement is hereby amended and restated in its entirety as follows:

(d)  The definition of “Term SOFR” in Section 1.01 of the Existing Credit Agreement is hereby amended to add the following proviso to the end of such definition:

(b)           Each Lender shall give prompt notice to the Borrowers upon such Lender becoming aware it is a Specified Foreign Entity.

(i)   Section 8.05 of the Existing Credit Agreement is hereby amended to add the words “or a Specified Foreign Entity” to the end of clause (iv) of that Section.

(j)   Section 9.08 of the Existing Credit Agreement is hereby amended to add the following sentence at the end of such Section:

For the avoidance of doubt, nothing herein prohibits any individual from communicating or disclosing information regarding suspected violations of laws, rules, or regulations to a governmental, regulatory, or self-regulatory authority without any notification to any Person.

(a)  The execution, delivery and performance by such Borrower of this Agreement and the Notes are within such Borrower’s powers, have been duly authorized by all necessary company action, require no action by or in respect of, or filing with, any Governmental Authority (except for consents, authorizations or filings which have been obtained or made, as the case may be, and are in full force and effect) and do not contravene, or constitute a default under, any provision of applicable law or regulation or of the articles of incorporation, by laws, certificate of formation or the limited liability company agreement of such Borrower or of any material agreement, judgment, injunction, order, decree or other instrument binding upon such Borrower or result in the creation or imposition of any Lien on any asset of such Borrower or any of its Material Subsidiaries.

(b)  This Agreement constitutes a valid and binding agreement of such Borrower and each Note, if and when executed and delivered by it in accordance with this Agreement, will constitute a valid and binding obligation of such Borrower, in each case enforceable in accordance with its terms, except as the same may be limited by bankruptcy, insolvency or similar laws affecting creditors’ rights generally and by general principles of equity.

(c)  Each of the representations and warranties made by such Borrower in Article 4 of the Existing Credit Agreement is true and correct in all material respects on and as of the date hereof, except to the extent such representations and warranties expressly relate to an earlier date (in which case they shall be true and correct on and as of such earlier date); provided that any representation and warranty that is qualified by materiality or material adverse effect shall be true and correct in all respects on and as of the date hereof, except to the extent such representations and warranties expressly relate to an earlier date (in which case they shall be true and correct on and as of such earlier date).

(d)  No Event of Default or Default has occurred and is continuing as of the date hereof.

This Agreement is subject to the Electronic Execution provisions contained in Section 9.10(b) of the Existing Credit Agreement.

EACH BORROWER AND EACH LENDER PARTY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

SECTION 12. WAIVER OF JURY TRIAL. EACH OF THE BORROWERS, THE AGENTS, THE ISSUING LENDERS AND THE LENDERS, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.
