EXHIBIT 5.2


                                                 June 1, 2004



Ladies and Gentlemen:

     I serve as counsel to ENERSIS S.A., a Chilean corporation (the "Company"),
and hereby render this opinion in connection with the Company's offer (the
"Exchange Offer") to exchange its 7.375% notes due 2014 (the "New Notes") for
any and all of its outstanding 7.375% notes due 2014 (the "Old Notes").

     I have examined originals or copies, certified or otherwise identified to
my satisfaction, of such documents, corporate records, certificates of public
officials and other instruments as I have deemed necessary or advisable for the
purpose of rendering this opinion.

     Upon the basis of the foregoing, I am of the opinion that:

     A.  The Company has been duly incorporated and is validly existing as a
publicly held limited liability stock corporation (sociedad anonima abierta)
under the laws of the Republic of Chile, has the power and authority (corporate
and other) to own its property and to conduct its business as described in the
Registration Statement and is duly qualified to transact business as a Chilean
corporation and is in good standing in Chile, except to the extent that the
failure to be so qualified or be in good standing would not have a material
adverse effect on the Company and its subsidiaries organized under the laws of
the Republic of Chile (the "Chilean Subsidiaries"), taken as a whole.

     B.  The issuance of the New Notes is within the Company's corporate power.

     C.  The New Notes have been duly authorized and, when duly executed,
authenticated and delivered in exchange for the Old Notes in accordance with the
terms of the Indenture and the Exchange Offer, will be valid and binding
obligations of the Company enforceable in accordance with their terms, subject
to applicable bankruptcy, insolvency and similar laws affecting creditors'
rights generally and equitable principles of general applicability.

     D.  The issuance of the New Notes will not contravene any provision of
Chilean law or the charter or corporate governance documents of the Company or
any agreement or other instrument binding upon the Company or the Chilean
Subsidiaries, that is material to the Company or the Chilean Subsidiaries, taken
as a whole, or any judgment, order or decree of any Chilean governmental body,
agency or court having jurisdiction over the Company or the Chilean
Subsidiaries.

     I am qualified to practice law in Chile and the foregoing opinion is
limited to the laws of Chile.

     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement relating to the Exchange Offer. I also consent to the
reference to me under the caption "Legal Matters" in the Prospectus contained in
such Registration Statement.

     This opinion is rendered in connection with the above matter and may not be
relied upon for any other purpose, except that Deutsche Bank, as Exchange Agent
for the Exchange Offer, may rely upon this opinion as if it were addressed
directly to it.

                                         Very truly yours,


                                        /s/ Domingo Valdes
                                            --------------
