                     [Letterhead of CMS Energy Corporation]




CMS Energy Corporation
CMS Energy Michigan Limited Partnership
Fairlane Plaza South, Suite 1100
330 Town Center Road
Dearborn, Michigan  38126


   I refer to the Registration Statement on Form S-3 (the "Registration
Statement") being filed by CMS Energy Corporation, a Michigan corporation ("CMS
Energy"), and CMS Energy Michigan Limited Partnership, a Michigan limited
partnership ("CMS Energy Michigan"), as co-registrants, with the Securities and
Exchange Commission (the "SEC") under the Securities Act of 1933, as amended
(the "Securities Act"), relating to the shelf registration of $200,000,000 of
securities (the "Securities") of CMS Energy and CMS Energy Michigan.
Capitalized terms not otherwise defined herein have the respective meanings
specified in the Registration Statement.

   I am familiar with the proceedings to date with respect to the proposed
issuance and sale of the Securities and have examined such records, documents
and questions of law, and satisfied myself as to such matters of fact, as I
have considered relevant and necessary as a basis for this opinion.

   Based on the foregoing, I am of the opinion that:

                1.  CMS Energy is duly incorporated and validly existing under
         the laws of the State of Michigan.  CMS Energy Michigan has been duly
         formed and is validly existing as a limited partnership under the laws
         of the State of Michigan.

                2.  CMS Energy has corporate power and authority to execute and
         deliver the Subordinated Debt Indenture and to authorize and sell the
         Subordinated Debt Securities pursuant thereto, and to sell the Senior
         Debt Securities pursuant to the Senior Debt Indenture.

                3.  Each series of Debt Securities will be legally issued and
         binding obligations of (except to the extent enforceability may be
         limited by applicable bankruptcy, insolvency, reorganization,
         moratorium, fraudulent transfer or other similar laws affecting the
         enforcement of creditors' rights generally and by the effect of
         general principles of equity, regardless of whether
   2

         enforceability is considered in a proceeding in equity or at law)
         when:  (i) the Registration Statement, as finally amended (including
         any necessary post-effective amendments), shall have become effective
         under the Securities   Act and the Subordinated Debt Indenture
         (including any necessary supplemental indenture) shall have been
         qualified under the Trust Indenture Act of 1939, as amended, and duly
         executed and delivered by CMS Energy and the Subordinated Debt
         Trustee; (ii) a Prospectus Supplement with respect to such series of
         Debt Securities shall have been filed (or mailed for filing) with the
         SEC pursuant to Rule 424 under the Securities Act; (iii) CMS Energy's
         Board of Directors or a duly authorized committee thereof shall have
         duly adopted final resolutions authorizing the issuance and sale of
         such series of Debt Securities as contemplated by the Registration
         Statement and the Subordinated Debt Indenture or the Senior Debt
         Indenture, as the case may be; and (iv) such series of Debt Securities
         shall have been duly executed and authenticated as provided in the
         Subordinated Debt Indenture or the Senior Debt Indenture, as the case
         may be, and such resolutions, and shall have been duly delivered to
         the purchasers thereof against payment of the agreed consideration
         therefor.

                4.  The CMS Energy Common Stock, the Class G Common Stock and
         the CMS Energy Preferred Stock will be legally issued, fully paid and
         non-assessable when:  (i) the Registration Statement, as finally
         amended, shall have become effective under the Securities Act; (ii) in
         the case of the Class G Common Stock only, the shareholders of CMS
         Energy shall have approved the Charter Amendment and the Certificate
         of Amendment shall have been filed with the Michigan Department of
         Commerce; (iii) CMS Energy's Board of Directors or a duly authorized
         committee thereof shall have duly adopted final resolutions
         authorizing the issuance and sale of the CMS Energy Common Stock,
         Class G Common Stock or CMS Energy Preferred Stock, as the case may
         be, as contemplated by the Registration Statement; (iv) in the case of
         the CMS Energy Preferred Stock only, a certificate of designation
         relating to the series of CMS Energy Preferred Stock to be issued and
         sold, as contemplated by the Redemption Statement, shall have been
         filed with the Michigan Department of Commerce; and (v) certificates
         representing the CMS Energy Common Stock, Class G Common Stock and CMS
         Energy Preferred Stock, as the case may be, shall have been duly
         executed, countersigned and registered and duly delivered to the
         purchasers thereof against payment of the agreed consideration
         therefor.
   3




                5.  The CMS Energy Michigan Preferred Securities, which are
         covered by the Registrations Statement, will be legally issued, fully
         paid and, assuming that the holders of the CMS Energy Michigan
         Preferred Securities as limited partners of CMS Energy Michigan do not
         participate in the control of the business of CMS Energy Michigan,
         non-assessable limited partner interest in CMS Energy Michigan when:
         (i) the Registration Statement, as finally amended, shall have become
         effective under the Securities Act; (ii) CMS Energy, as general
         partner of CMS Energy Michigan, shall have duly adopted an Action or
         Actions providing for the issuance and sale of such CMS Energy
         Michigan Preferred Securities and the terms thereof, as provided in
         the Registration Statement, and such Action or Actions shall have been
         filed with the Michigan Department of Commerce; and (iii) certificates
         representing the CMS Energy Michigan Preferred Securities shall have
         been duly executed, countersigned and registered and duly delivered to
         the purchasers thereof against payment of the agreed consideration
         therefor.

       For the purposes of this opinion, I have assumed that there will be no
changes in the laws currently applicable to CMS Energy and CMS Energy Michigan,
respectively, and that such laws will be the only laws applicable to CMS Energy
and CMS Energy Michigan, respectively.

       I do not find it necessary for the purposes of this opinion to cover,
and accordingly I express no opinion as to, the application of the securities
or blue sky laws of the various states to sales of the Securities.

       I am a member of the bar of the State of Michigan and I express no
opinion as to the law of any jurisdiction other than State of Michigan and the
federal law of the United States of America.

       I hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to all references to me included in or made a part
of the Registration Statement.

                                                 Very truly yours,


                                                 /s/ DENISE M. STURDY
