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 14th day of April, 2008.

                                         /s/ Polly L. Gault
