                                                        After reviewing your

   1.                                                   Please expand your
disclosure to address the suitability, adequacy, productive capacity,
                                                        and extent of
utilization of your principal physical properties for each period to comply
                                                        with Instruction 1 to
Item 102 of Regulation S-K.

   2.                                                   Please expand your
discussion and analysis to address changes in revenues with reference
                                                        to both volumes and
prices to comply with Item 303(b)(2)(iii) of Regulation S-K.

                                                        For example, quantify
the volumes gathered, stored and transported for each period,
                                                        address the reasons for
material changes in volumes, and provide similar commentary on

3.       We note that you report a change in capital structure in which DTE Gas
Enterprises, LLC
         was converted into a Delaware corporation with the issuance of 1,000
common shares to
         replace the member interests on January 13, 2021, and that an
incremental 96,731,466
         common shares were issued to the parent or its shareholders, either
prior to or in
         connection with the spin-off on July 1, 2021.

         We see that you have given retrospective treatment to the issuance of
these shares in
         computing and presenting EPS for all periods, consistent with the
guidance pertaining to
         changes in capital structure in FASB ASC 260-10-55-12. However, you
have taken a
         different approach in the Balance Sheets and Statements of Changes in
Stockholders
         Equity on pages 57 and 59, which appears to be contrary to the
guidance in SAB Topic
         4:C, Rule 3-04 of Regulation S-X, and FASB ASC 250-10-45-21.

         Tell us how you propose to resolve these inconsistencies considering
the requirements
         mentioned above in amendments to your annual and subsequent interim
reports, or explain
         to us why you believe this guidance would not apply to you, if this is
your view.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.

      You may contact Jenifer Gallagher, Staff Accountant at (202) 551-3706 or
Karl Hiller,
Branch Chief at (202) 551-3686 with any questions.
