                  Re:      TXU Capital I

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for Texas Utilities
Company, a Texas corporation (the "Company"), and TXU Capital I, a Delaware
business trust (the "Trust"), in connection with the matters set forth herein.
At your request, this opinion is being furnished to you.

                  For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

                  (a)     The Certificate of Trust of the Trust, dated as of
December 3, 1998 (the "Certificate"), as filed in the office of the Secretary of
State of the State of Delaware (the "Secretary of State") on December 3, 1998;

                  (b)    The Trust Agreement of the Trust, dated as of
December 3, 1998, among the Company and the trustees of the Trust named therein;

                  (c)    The Registration Statement (the "Registration
Statement") on Form S-3, including a preliminary prospectus (the "Prospectus"),
relating to the undivided beneficial interests in the assets of the Trust (each,
a "Security" and collectively, the "Securities"), as proposed to be filed by the
Company and the Trust with the Securities and Exchange Commission on or about
December 10, 1998;

                  (d)    A form of Amended and Restated Trust Agreement of
the Trust (including Exhibits A, B and D thereto) (the "Trust Agreement"), to be
entered into among the Company, the trustees of the Trust named therein, and the
holders, from time to time, of undivided beneficial interests in the assets of
the Trust, filed as an exhibit to the Registration Statement; and

                  (e)    A Certificate of Good Standing for the Trust, dated
December 4, 1998, obtained from the Secretary of State.

                  Initially capitalized terms used herein and not otherwise
defined are used as defined in the Trust Agreement.

                  For purposes of this opinion, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

                  With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Trust Agreement constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Trust Agreement and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation or due
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are signatories to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) the due authorization, execution and delivery by all parties
thereto of all documents examined by us, (vi) the receipt by each Person to whom
a Security is to be issued by the Trust (collectively, the "Security Holders")
of a certificate in the form attached as Exhibit D to the Trust Agreement
evidencing ownership of such Security in the name of such Person and the payment
for the Security acquired by it, in accordance with the Trust Agreement and the
Registration Statement, and (vii) that the Securities are issued and sold to the
Security Holders in accordance with the Trust Agreement and the Registration
Statement.  We have not participated in the preparation of the Registration
Statement and assume no responsibility for its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1.     The Trust has been duly created and is validly
existing in good standing as a business trust under the Delaware Business Trust
Act.

                  2.     The Securities will represent valid and, subject to
the qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

                  3.     The Security Holders, as beneficial owners of the
Trust, will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Security Holders may
be obligated to make payments as set forth in the Trust Agreement.

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement. In
addition, we hereby consent to the use of our name under the heading "Experts
and Legality" in the Prospectus. In giving the foregoing consents, we do not
thereby admit that we come within the category of Persons whose consent is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Securities and Exchange Commission thereunder. Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.


                                       Very truly yours,

                                       /s/ Richards, Layton & Finger, P.A.
