        The undersigned hereby constitutes and appoints, Barbara E. Mathews, Paige W. R. White,
Kathleen Brennan de Jesus, Michael A. Henry, Keith J. Larson, Darla 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 3rd
day of April, 2008.
