Legal Matters:
In the opinion of Duke Energy Corporation’s counsel, when the notes offered by this pricing supplement have been executed and issued by Duke Energy Corporation and authenticated by the
trustee pursuant to an Indenture dated as of June 3, 2008, as amended and supplemented, between Duke Energy Corporation and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Indenture”), and delivered against payment
as contemplated herein, such notes will constitute valid and binding obligations of Duke Energy Corporation, enforceable in accordance with their terms. The opinion expressed above is subject to specified qualifications, assumptions and limitations,
including that the validity or enforcement of any agreements or instruments may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and by general principles of
equity (regardless of whether enforceability is considered in a proceeding in equity or at law) and that such counsel does not express any opinion as to the applicability or effect of any fraudulent transfer, preference or similar law on any
agreements or instruments or any transactions contemplated by such opinion. In addition, this opinion is subject to customary assumptions, including, other than with respect to Duke Energy Corporation, (i) that the parties to documents,
including the Indenture, relevant to such opinion had or will have the power, corporate or otherwise, to enter into and perform all obligations thereunder, (ii) the due authorization thereof by all requisite action, corporate or other by such
parties, (iii) the execution and delivery by such parties of such documents, and (iv) the validity and binding effect of such documents on such parties, all as stated in the letter of such counsel dated November 13, 2012, which has
been filed as Exhibit 5.1 to a Current Report on Form 8-K filed by Duke Energy Corporation on November 13, 2012.
