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

Section 16(a) of the Securities Exchange Act of 1934
or any rule or regulation of the SEC;

a company including Edison International and/or SCE,
or as a trustee, beneficiary or settlor of a trust, Forms

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  7th day of January,
2011.
