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 "stocktickerSEC") 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 stocktickerSEC of reports required by Section 16(a) of the
             Securities Exchange Act of 1934 or any rule or regulation of the
             stocktickerSEC;

       (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 6th day of December, 2011.

                                        /s/ Peter J. Taylor
