Document

Reference is made to the Post-Effective Amendment to the registration statement on Form S-8 (the “Post-Effective Amendment”) filed by DTE Energy Company, a Michigan corporation (the “Company”) with the Securities and Exchange Commission relating to the offer and sale of previously registered shares of common stock, without par value and related rights (the “Common Stock”), of the Company under the DTE Energy Company 2025 Long-Term Incentive Plan (the “Plan”).

I, as Vice President and Deputy General Counsel of the Company, in conjunction with an attorney or attorneys under my general supervision, have examined such certificates, instruments and documents (collectively, “Documents”) and reviewed such questions of law as I have considered necessary or appropriate for the purposes of this opinion. In rendering this opinion, I have assumed, without independent verification, that: (i) all signatures are genuine; (ii) all Documents submitted to me as originals are authentic; and (iii) all Documents submitted to me as copies conform to the originals of such Documents. My review has been limited to examining the Documents and applicable law.

2. The issuance of shares of Common Stock has been duly authorized by all requisite action (corporate or otherwise) of the Company, and when such shares of Common Stock shall have been duly issued and delivered by the Company in accordance with the terms of the Plan, such Common Stock will be validly issued, fully paid and non-assessable.

I am qualified to practice law in the State of Michigan, and in rendering this opinion, my examination of matters of law has been limited to, and I express no opinion as to the laws of any jurisdictions other than, the laws of the State of Michigan and the Federal laws of the United States.

I consent to the filing of this opinion as an exhibit to the Post-Effective Amendment and to the reference to me in the materials constituting the Plan prospectus. In giving such consent, I do not thereby admit that I am in the category of persons whose consent is required under Section 7 of the Securities Act.
