Registration Statement on Form SF-1

Ladies and Gentlemen:

We have acted as counsel to Duke Energy Progress, LLC (“DEP”) and Duke Energy Progress NC Storm Funding LLC, a Delaware limited liability company (the “Company”), in connection with the issuance and sale of $769,627,000 aggregate principal amount of the Company’s Senior Secured Storm Recovery Bonds, Series A (the “Bonds”), covered by the Registration Statement on Form SF-1 (Registration Nos. 333-259315 and 333-259315-01) filed on September 3, 2021 and as amended by (i) Amendment No. 1 thereto filed on October 28, 2021 and (ii) Amendment No. 2 thereto filed on November 1, 2021 (collectively, the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”) and the preliminary prospectus, subject to completion, dated November 15, 2021, which was filed with the Commission pursuant to Rule 424(b)(3) of the rules and regulations of the Commission and the final prospectus, dated November 17, 2021, which was filed with the Commission pursuant Rule 424(b)(1) of the rules and regulations of the Commission. .

The Bonds were issued under an Indenture (the “Base Indenture”) between the Company and The Bank of New York Mellon Trust Company, National Association, as trustee (the “Trustee”), as supplemented by a Series Supplement establishing the forms, terms and other provisions of the Bonds (the “Series Supplement” and, together with the Base Indenture, the “Indenture”) between the Company and the Trustee. The Bonds were sold pursuant to the terms of the Underwriting Agreement, dated November 17, 2021 (the “Underwriting Agreement”), among the Company, DEP and the underwriters named therein.

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

We are familiar with the proceedings taken by the Company and DEP in connection with the authorization, issuance and sale of the Bonds. In rendering the opinion expressed below, we have examined and relied upon copies of the Registration Statement and the exhibits filed therewith, and the Indenture. We have also examined originals, or copies of originals certified to our satisfaction, of such agreements, documents, certificates and statements of government officials and other instruments, and have examined such questions of law and have satisfied ourselves as to such matters of fact, as we have considered relevant and necessary as a basis for this opinion. We have assumed (i) the genuineness of all signatures, (ii) the authenticity of all documents submitted to us as originals and (iii) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents. We have also assumed that the Indenture will be the valid and legally binding obligation of the Trustee. In delivering the opinion expressed below, as to factual matters, we have relied on certifications and other written or oral statements of governmental and other public officials and of officers and representatives of the Company, DEP, the underwriters of the Bonds and the Trustee without independent verification.
