Exhibit 24

                                         POWER OF ATTORNEY

        The undersigned hereby constitutes and appoints Beverly P. Ryder, Barbara E. Mathews, Paige
W. R. White, Jeffrey Shieh, Michael A. Henry, Darla F. Forte, Eileen B. Guerrero and Marga Rosso
of Edison International and/or Southern California Edison Company ("SCE"), signing singly, the
undersigned's true and lawful attorney-in-fact to:

       (1) 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;

       (2) 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

       (3) 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
Secretary of Edison International or SCE.  Notwithstanding anything to the contrary contained
herein, upon receipt by the 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 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 25 day of July, 2005.
