F. Forte, Marga Rosso, Sarah C. Perez, and Nihal P. Perera of Edison
International and/or Southern California Edison Company ("SCE"), signing singly,
the undersigned's true and lawful attorney-in-fact to:

      (1)prepare, execute in the undersigned's name and on the undersigned's
         behalf, and submit to the U.S. Securities and Exchange Commission (the
         "SEC") a Form ID, including amendments thereto, and any other documents
         necessary or appropriate to obtain codes and passwords enabling the
         undersigned to make electronic filings with the SEC of reports required
         by Section 16(a) of the Securities Exchange Act of 1934 or any rule or
         regulation of the SEC;

      (2)execute for and on behalf of the undersigned, in any capacity including
         without limitation in the undersigned's capacity as an officer and/or
         director of a company including Edison International and/or SCE, or as a
         trustee, beneficiary or settlor of a trust, Forms 3, 4 and 5, and all
         amendments and/or supplements thereto, in accordance with Section 16(a)
         of the Securities Exchange Act of 1934 and the rules thereunder;

      (3)do and perform any and all acts for and on behalf of the undersigned
         which may be necessary or desirable to complete and execute any such
         Forms 3, 4 and 5, and all amendments and/or supplements thereto, and
         timely file such forms with the United States Securities and Exchange
         Commission and any stock exchange or other authority; and

      (4)take any other action of any type whatsoever in connection with the
         foregoing which, in the opinion of such attorney-in-fact, may be of
         benefit to, in the best interest of, or legally required by, the
         undersigned, it being understood that the documents executed by such
         attorney-in-fact on behalf of the undersigned pursuant to this Power of
         Attorney shall be in such form and shall contain such terms and
         conditions as such attorney-in-fact may approve in such
         attorney-in-fact's discretion.

      The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution, hereby ratifying
and confirming all that such attorney-in-fact, or such attorney-in-fact's
substitute or substitutes, shall lawfully do or cause to be done by virtue of
this Power of Attorney and the rights and powers herein granted.  The undersigned
acknowledges that the foregoing attorneys-in-fact, in serving in such capacity at
the request of the undersigned, are not assuming, nor is Edison International or
SCE assuming, any of the undersigned's responsibilities to comply with Section 16
of the Securities Exchange Act of 1934.  The undersigned agrees that the
foregoing attorneys-in-fact may rely entirely on information furnished orally or
in writing by me to any of them.  The undersigned also agrees to indemnify and
hold harmless Edison International and SCE and the foregoing attorneys-in-fact
against any losses, claims, damages or liabilities (or actions in these respects)
that arise out of or are based upon any untrue statements or omission of
necessary facts in the information provided by me to any of them for purposes of
executing, acknowledging, delivering or filing Forms 3, 4 and 5 and all
amendments and/or supplements thereto, and agrees to reimburse such companies and
the attorneys-in-fact for any legal or other expenses reasonably incurred in
connection with investigating or defending against any such loss, claim, damage,
liability or action.

      This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 with respect to the
undersigned's holdings of and transactions in securities for which such forms are
required to be filed including those securities issued by Edison International
and/or SCE, unless earlier revoked by the undersigned in a signed writing
delivered by registered or certified mail, return receipt requested, to the
Corporate Secretary of Edison International or SCE.  Notwithstanding anything to
the contrary contained herein, upon receipt by the Corporate Secretary of Edison
International or SCE, this Power of Attorney shall supersede and replace all
prior Powers of Attorney executed by me and filed with the Edison International
or SCE Corporate Secretary appointing Edison International and/or SCE employees
to file Forms 3, 4 and 5 with the United States Securities and Exchange
Commission under Section 16(a) of the Securities Exchange Act of 1934; provided,
however, any indemnification and reimbursement agreement contained therein shall
survive the termination of said Powers of Attorney.

      IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 25th day of March, 2008.

                                         /s/ Charles B. Curtis
