                     RE: Registration Statement on Form S-3

Ladies and Gentlemen:

      I am Assistant General Counsel of CMS Energy Corporation and have acted as
special counsel to Consumers Energy Company (the "Company") in connection with
the Registration Statement on Form S-3 (the "Registration Statement") being
filed by the Company and Consumers Energy Company Financing V and Consumers
Energy Company Financing VI (each a "Trust" and collectively, the "Trusts") with
the Securities and Exchange Commission (the "Commission") under the Securities
Act of 1933, as amended (the "Securities Act"), relating to the registration of
$1,500,000,000 of (i) trust preferred securities of the Trusts ("Preferred
Securities"); (ii) Subordinated Debentures of the Company ("Debentures"); (iii)
Senior Notes of the Company ("Senior Notes"); (iv) First Mortgage Bonds of the
Company ("First Mortgage Bonds") and (v) the guarantee of the Preferred
Securities by the Company ("Preferred Securities Guarantee"). (The foregoing
offered securities, collectively, the "Securities".) The Preferred Securities
Guarantee is to be issued pursuant to the Preferred Securities Guarantee
Agreement (the "Preferred Securities Guarantee Agreement") to be entered into
between the Company and the Bank of New York, as trustee (the "Guarantee
Trustee"). The Debentures are to be issued under an indenture between the
Company and The Bank of New York, as trustee (the "Indenture Trustee"), and one
or more supplemental indentures thereto (collectively, the "Debenture
Indenture"). The Senior Notes are to be issued under a senior note indenture
between the Company and The JPMorgan Chase Bank, as trustee (the "Senior Note
Trustee") that may include one or more supplemental indentures thereto
(collectively the "Senior Note Indenture"). The First Mortgage Bonds are to be
issued under the mortgage indenture between the Company and JPMorgan Chase Bank,
as mortgage

trustee (the "First Mortgage Bond Trustee") that may include one or
more supplemental indentures thereto (collectively the "First Mortgage Bond
Indenture"). Capitalized terms not otherwise defined herein have the respective
meanings specified in the Registration Statement.

            In rendering this opinion, I have examined and relied upon a copy of
the Registration Statement. I have also examined, or have arranged for the
examination by an attorney or attorneys under my general supervision of,
originals, or copies of originals certified to my satisfaction, of such
agreements, documents, certificates and other statements of governmental
officials and other instruments, and have examined such questions of law and
have satisfied myself as to such matters of fact as I have considered relevant
and necessary as a basis for this opinion. I have assumed the authenticity of
all documents submitted to me as originals, the genuineness of all signatures,
the legal capacity of all natural persons and the conformity with the original
documents of any copies thereof submitted to me for examination.

      Based on the foregoing, it is my opinion that:

      1.    The Company is duly incorporated and validly existing under the laws
            of the State of Michigan.

      2.    The Company has the corporate power and authority (i) to execute and
            deliver the Preferred Securities Guarantee Agreement, the Debenture
            Indenture, the Senior Note Indenture and the First Mortgage Bond
            Indenture, (ii) to authorize and sell the Debentures pursuant to the
            Debenture Indenture, (iii) to authorize and sell the Senior Notes
            pursuant to the Senior Note Indenture and (iv) to authorize and sell
            the First Mortgage Bonds pursuant to the First Mortgage Bond
            Indenture.

      3.    The Preferred Securities Guarantee will be a legally issued and
            binding obligation of the Company (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 principals of equity, regardless of whether
            enforceability is considered in a proceeding in equity or at law)
            when (i) the Registration Statement, as finally amended (including
            any necessary post-effective amendment), shall have become effective
            under the Securities Act; (ii) the Preferred Securities Guarantee
            shall have been qualified under the Trust Indenture Act of 1939, as
            amended (the "Trust Indenture Act"), and duly executed and delivered
            by the Company and the Guarantee Trustee; (iii) the Preferred
            Securities shall have been legally issued; and (iv) the Preferred
            Securities Guarantee shall have been duly executed and delivered as
            provided in the Preferred Securities Guarantee Agreement.

      4.    The Debentures will be legally issued and binding obligations of the
            Company (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 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 Debenture Indenture shall have been
            qualified under the Trust Indenture Act, and duly executed and
            delivered by the Company and the Indenture Trustee; (ii) the
            Company's Board of Directors or duly authorized committee thereof
            shall have duly adopted final resolutions authorizing the issuance
            and sale of the Debentures, as contemplated by the Registration
            Statement and the Debenture Indenture; and (iii) the Debenture
            Indenture under which such Debentures are to be issued shall have
            been duly executed as provided in such resolutions and the
            Debentures shall have been duly executed and authenticated as
            provided in the Indenture, and shall have been duly delivered to the
            purchasers thereof against payment of the agreed consideration
            therefor.

      5.    The Senior Notes will be legally issued and binding obligations of
            the Company (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 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 Senior Note Indenture shall have been
            qualified under the Trust Indenture Act, and duly executed and
            delivered by the Company and the Senior Note Trustee; (ii) the
            Company's Board of Directors or duly authorized committee thereof
            shall have duly adopted final resolutions authorizing the issuance
            and sale of the Senior Notes, as contemplated by the Registration
            Statement and the Senior Note Indenture; and (iii) the Senior Note
            Indenture under which such Senior Notes are to be issued shall have
            been duly executed as provided in such resolutions and the Senior
            Notes shall have been duly executed and authenticated as provided in
            the Senior Note Indenture, and shall have been duly delivered to the
            purchasers thereof against payment of the agreed consideration
            therefor.

      6.    The First Mortgage Bonds will be legally issued and binding
            obligations of the Company (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 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 First Mortgage Bond Indenture shall have
            been qualified under the Trust Indenture Act, and duly executed and
            delivered by the Company and the First Mortgage Bond Trustee; (ii)
            the Company's Board of Directors or duly authorized committee
            thereof shall have duly adopted final resolutions authorizing the
            issuance and sale of the First Mortgage Bonds, as contemplated by
            the Registration Statement and the First Mortgage Bond Indenture;
            and (iii) the First Mortgage Bond Indenture under which such First
            Mortgage Bonds are to be issued shall have been duly executed as
            provided in such resolutions and the First Mortgage Bonds shall have
            been duly executed and authenticated as provided in the First
            Mortgage Bond Indenture, and shall have been duly delivered to the
            purchasers thereof against payment of the agreed consideration
            therefor.

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

      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 the execution and delivery of the
Preferred Securities Guarantee or the sale of the Securities.

      The opinions expressed herein are limited to the laws of the State of
Michigan and the Federal laws of the United States of America.

      I note that each indenture and the debt securities will be governed by,
and construed in accordance with, the laws of the State of Michigan unless the
laws of another jurisdiction shall mandatorily apply. The rights, duties and
obligations of the subordinate note Trustee are governed by and construed in
accordance with the laws of the State of New York.

      I hereby consent to the filing of this opinion as an exhibit to the
Company's. Registration Statement on Form S-3 relating to the Securities and to
all references to me included in or made a part of the Registration Statement.

Very truly yours,

/s/ Robert C. Shrosbree
