Perera of Edison International and/or Southern California Edison

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 25 day of June, 2009.
