          Ladies and Gentlemen:

               Reference is made to the Registration Statement
          (Registration Statement) on Form S-3 to be filed by Texas
          Utilities Company (Company) and TXU Capital I (Trust) on or about

          registration of (i) securities (Securities) in an aggregate
          amount of $400,000,000, including (a) debt securities (Debt
          Securities) of the Company to be issued pursuant to the terms of
          one or more indentures (each a Debt Securities Indenture); and
          (b) preferred trust securities (Preferred Trust Securities) of
          the Trust; (ii) the guarantee of the Company with respect to the

          (Subordinated Indenture) and purchased by the Trust with the
          proceeds of the sale of the Preferred Trust Securities.  In
          connection therewith, we have reviewed such documents and records
          as we have deemed necessary to enable us to express an opinion on
          the matters covered hereby.

               Based upon the foregoing, we are of the opinion that:

               1.   The Company is a corporation validly organized and
          existing under the laws of the State of Texas.

               2.   All requisite action necessary to make any Debt
          Securities valid, legal and binding obligations of the Company
          will have been taken when:

                    a.    A Debt Securities Indenture with respect to such
          Debt Securities shall have been executed and delivered by a duly
          authorized officer or representative of the Company and by the
          trustee under such Debt Securities Indenture; and

                    b.   The Board of Directors of the Company, or an
          officer duly authorized thereby, shall have taken such action,
          pursuant to the terms of such Debt Securities Indenture, as may
          be necessary to fix and determine the terms of such Debt
          Securities, and such Debt Securities shall have been issued and
          delivered in accordance with the terms and provisions of such
          Debt Securities Indenture.

               3.   All requisite action necessary to make any Guarantee a
          valid, legal and binding obligation of the Company will have been
          taken when the Board of Directors of the Company, or an officer
          duly authorized thereby, shall have taken such action as may be
          necessary to fix and determine the terms of such Guarantee and
          such Guarantee shall have been duly executed and delivered by the
          parties thereto.

               4.   All requisite action necessary to make any Subordinated
          Debentures valid, legal and binding obligations of the Company
          will have been taken when:

                     a.  A Subordinated Indenture shall have been executed
          and delivered by a duly authorized officer or representative of
          the Company and by the trustee under such Subordinated Indenture;
          and

                    b.   The Board of Directors of the Company, or an
          officer duly authorized thereby, shall have taken such action,
          pursuant to the terms of such Subordinated Indenture, as may be
          necessary to fix and determine the terms of such Subordinated
          Debentures, and such Subordinated Debentures shall have been
          issued and delivered in accordance with the terms and provisions
          of such Subordinated Indenture.

                    We are members of the State Bar of Texas and do not
          hold ourselves out as experts on the laws of New York.  As to all
          matters of New York law, we have with your consent relied upon an
          opinion of even date herewith addressed to you by Thelen, Reid &
          Priest, LLP of New York, New York.

                    We hereby consent to the use of this opinion as an
          exhibit to the Registration Statement and to the use of our name
          as counsel in the Registration Statement and as authority for
          certain of the statements incorporated by reference therein.  

                                             Very truly yours,
