Ladies and Gentlemen:

We have acted as counsel for Consumers Energy Company, a Michigan corporation (“Consumers Energy”), and Consumers 2023 Securitization Funding LLC, a Delaware limited liability company (the “Company”), in connection with the issuance and sale by the Company of $646,000,000 aggregate principal amount of Senior Secured Securitization Bonds, Series 2023A (the “Securities”) pursuant to the Registration Statement on Form SF-1 (File Nos. 333-274648 and 333-274648-01) (the “Registration Statement”), as amended, filed by Consumers Energy and the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (the “Act”), and related preliminary prospectus, subject to completion, dated November 13, 2023 contained therein (the “Preliminary Prospectus”) and prospectus dated December 5, 2023 (the “Final Prospectus” and, together with the Preliminary Prospectus, the “Prospectus”) relating to the offer and sale of the Securities. The Securities have been issued under the Indenture dated as of December 12, 2023, between the Company and The Bank of New York Mellon, a New York banking corporation, as trustee, securities intermediary and account bank (the “Trustee”), in the form filed as Exhibit 4.1 to the Registration Statement, together with a Series Supplement dated as of December 12, 2023 between the Company and the Trustee establishing the form and terms of such Securities in the form included in such Exhibit 4.1 to the Registration Statement (collectively, the “Indenture”).

We have reviewed the Registration Statement, the Prospectus, the Indenture and such other agreements, documents, records, certificates and other materials, and have reviewed and are familiar with such limited liability company proceedings and satisfied ourselves as to such other matters, as we have considered relevant or necessary as a basis for our opinions set forth in this letter. In such review, we have assumed the accuracy and completeness of all agreements, documents, records, certificates and other materials submitted to us, the conformity with the originals of all such materials submitted to us as copies (whether or not certified and including facsimiles), the authenticity of the originals of such materials and all materials submitted to us as originals, the genuineness of all signatures and the legal capacity of all natural persons, and that the Indenture has been duly authorized, executed and delivered by the Trustee. In delivering this letter, we have relied, without independent verification, as to factual matters, on certificates and other written or oral statements of governmental and other public officials and of officers and representatives of the Company, the underwriters of the Securities and the Trustee.

On the basis of the foregoing and subject to the other qualifications and limitations set forth herein, we are of the opinion that:
