          Re:  Certain United States Federal Tax Consequences
               ----------------------------------------------

Ladies and Gentlemen:

          We have acted as tax counsel to Sempra Energy, a Delaware corporation
(the "Issuer"), in connection with the Issuer's registration statement on Form
S-3 (No. 333-70640), and all amendments thereto (the "Registration Statement"),
previously declared effective by the Securities and Exchange Commission under
the Securities Act of 1933, as amended, relating to the proposed public offering
of Securities of the Issuer that may be offered and sold by the Issuer from time
to time as set forth in the prospectus dated November 15, 2001, which forms a
part of the Registration Statement.  This opinion is rendered in connection with
the registration, sale and issuance of up to 24,000,000 Equity Units (including
2,000,000 Equity Units subject to an over-allotment option) pursuant to a
prospectus supplement dated April 24, 2002 (the "Prospectus Supplement").  Terms
which are used but not otherwise defined herein shall have the meanings ascribed
to them in the Prospectus Supplement.

          In connection with our representation of the Issuer, you have
requested our opinion concerning the statements in the Prospectus Supplement
under the caption "Certain United States Federal Income Tax Consequences."  The
facts, as we understand them, and upon which with your permission we rely in
rendering the opinion herein, are set forth in the Registration Statement.

          We are opining herein as to the effect on the subject transaction only
of the federal income tax laws of the United States, and we express no opinion
with respect to the applicability thereto, or the effect thereon, of other
federal laws, the laws of any state or any other jurisdiction or as to any
matters of municipal law or the laws of any other local agencies within any
state.

          Based on such facts and assumptions and subject to the limitations set
forth in the Prospectus Supplement, the statements set forth in the Prospectus
Supplement under the caption "Certain United States Federal Income Tax
Consequences" insofar as they purport to summarize the provisions of specific
statutes and regulations referred to therein, are accurate summaries in all
material respects.

          No opinion is expressed as to any matter not discussed herein.
