Report of Independent Registered Public Accounting Firm


To the Southern California Edison Company
   Benefits Committee
Rosemead, California


We have  audited the  accompanying  statements  of net assets  available  for plan  benefits  of the Edison  401(k)
Savings  Plan (the  "Plan") as of December  31, 2004 and 2003,  and the related  statement of changes in net assets
available  for  plan  benefits  for  the  year  ended  December  31,  2004.  These  financial  statements  and  the
supplemental  schedule referred to below are the  responsibility of the Plan's  management.  Our  responsibility is
to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company  Accounting  Oversight Board (United
States).  Those standards require that we plan and perform the audit to obtain  reasonable  assurance about whether
the  financial  statements  are free of material  misstatement.  The Company is not  required to have,  nor were we
engaged  to  perform,  an  audit  of  its  internal  controls  over  financial   reporting.   Our  audits  included
consideration  of internal  control over financial  reporting as a basis for designing  audit  procedures  that are
appropriate  in the  circumstances,  but not for the purpose of expressing an opinion on the  effectiveness  of the
Plan's  internal  control  over  financial  reporting.  Accordingly  we  express  no such  opinion.  An audit  also
includes examining,  on a test basis,  evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting  principles used and significant  estimates made by management,  as well as evaluating the
overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present  fairly,  in all material  respects,  the net
assets  available for plan benefits as of December 31, 2004 and 2003,  and the changes in net assets  available for
plan benefits for the year ended December 31, 2004 in conformity with US generally accepted accounting principles.

Our audits  were  performed  for the  purpose of forming an opinion on the basic  financial  statements  taken as a
whole.  The  supplemental  schedule of assets (held at end of year) as of  December 31,  2004 is presented  for the
purpose of additional  analysis and is not a required part of the basic financial  statements but is  supplementary
information  required by the Department of Labor's Rules and  Regulations  for Reporting and  Disclosure  under the
Employee  Retirement  Income  Security Act of 1974.  The  supplemental  schedule has been subjected to the auditing
procedures  applied in our audits of the basic financial  statements  and, in our opinion,  is fairly stated in all
material respects in relation to the basic financial statements taken as a whole.

1.      Plan Description      The following  description of the Edison 401(k) Savings Plan (the Plan), provides
                              only general  information.  The Plan sponsor is the  Southern  California  Edison
                              Company  (the  Plan  Sponsor).  Participants  should  refer to the  Summary  Plan
                              Description  and Plan document,  as amended,  for a more complete  description of
                              the Plan's provisions.

                              Nature of Plan

                              Eligibility

                              The  Plan  is a  defined-contribution  plan  with  a  401(k)  feature,  in  which
                              qualifying  full-time  and  part-time  employees  of  Edison  International  (the
                              Company)  and  substantially  all of its  subsidiary  companies  are  eligible to
                              participate.  The Plan is subject to the  provisions  of the Employee  Retirement
                              Income  Security  Act of 1974  (ERISA).  An  employee,  as  defined  by the  Plan
                              document, is eligible to participate in the Plan immediately upon employment.

                              Subject  to  statutory  limits,  all  participants  may defer up to 84 percent of
                              eligible pay.  Participating  employers provide matching  contributions  from 2.8
                              to 4.5 percent (the  maximum  matching  contribution  was changed to 6.0 percent,
                              effective   January  1,  2005)  of  a   participant's   eligible   pay.   Certain
                              participating  subsidiaries  also provide a fixed profit sharing  contribution of
                              4.5 percent  (3.0  percent  effective  January 1, 2005) of eligible  pay each pay
                              period  and  a  variable  profit  sharing   contribution   annually  to  eligible
                              employees.  The Plan also accepts  rollover  contributions  from other  qualified

                              accounts  totaled  $6,283 and $12,827,  respectively.  These accounts are used to
                              reduce future employer  contributions.  During 2004, employer  contributions were
                              reduced by $382,990 from forfeited non-vested accounts.

                              Plan Trust

                              Plan  assets are held in trust  with State  Street  Bank and Trust  Company  (the
                              Trustee)  for the benefit of  participants  and their  beneficiaries.  The mutual
                              covenants  to which the Plan Sponsor and the Trustee  agree are  disclosed in the
                              Trust Agreement between the Plan Sponsor and the Trustee.

                              Plan Administration

                              The Plan is  administered  by the Southern  California  Edison  Company  Benefits
                              Committee (the Plan  Administrator).  Hewitt  Associates LLC is the Plan's record
                              keeper.  As of  December 31,  2004,  and  December 31,  2003,  the Plan  provided
                              investment  choices  in 48 and  50  investment  funds  respectively.  The  Plan's

                              The Plan  Sponsor pays the cost of  administering  the Plan,  including  fees and
                              expenses of the Trustee and record  keeper.  The fees,  taxes and other  expenses
                              incurred by the Trustee or  investment  managers in making  investments  are paid
                              out of the applicable  fund. This includes  brokerage fees for sales or purchases
                              of Edison  International  Common Stock on the open market.  No  additional  costs
                              are  incurred  in  connection  with sales of Edison  International  Common  Stock
                              within the trust or the transfer of assets between funds.

1.      Plan Description      Mutual funds pay fees to the Plan record  keeper for  administrative  services to
        (Continued)           participants  that would  otherwise have to be provided by the mutual funds.  The
                              majority  of fees  received  by the Plan  record  keeper  are used to reduce  the
                              record keeping and communication expenses of the Plan.

                              Participant Accounts

                              Each participant  account is increased for the  participant's  contribution,  the
                              employer's   contribution,   if   applicable,   and   allocations  of  investment
                              earnings/losses.  Allocation of earnings/losses  and expenses is based on account
                              balances,  as  defined.  The  benefit to which a  participant  is entitled is the
                              benefit  that  can be  provided  from the  vested  portion  of the  participant's
                              account.

                              Participant Loans

                              Participants  may borrow from their account,  a minimum of $1,000 to a maximum of
                              $50,000, with certain  restrictions.  Effective December 31, 2003, profit sharing
                              accounts  are not  available  for  loans.  Loan  transactions  are  treated  as a
                              transfer from (to) the investment fund to (from)  Participant  Loans.  Loan terms
                              range from one to four years for general  purpose loans or up to 15 years for the
                              purchase  of a primary  residence.  Loans  bear  interest  at Prime Rate plus one
                              percent.   Interest  rates  of  outstanding   loans  range  from  5.0 percent  to
                              10.5 percent  as of December  31, 2004.  Principal  and interest are paid ratably
                              through  payroll   deductions.   Some  separated   participants  may  repay  loan
                              obligations directly,  rather than through payroll deductions.  Participant Loans
                              amounted to  approximately  $59,099,000  and $64,017,000 as of December 31, 2004,
                              and 2003, respectively.

1.    Plan Description      Distribution to Participants
      (Continued)
                            Account  balances are  distributed  as soon as  practicable  after a  participant
                            dies,  becomes  entitled  to a  distribution  and  requests  a  distribution,  or
                            terminates  employment  with an account  balance of $5,000 or less.  Participants
                            may  otherwise   delay   distribution,   subject  to  the  minimum   distribution

                                     effective January 1, 2005) profit sharing  contribution each pay period
                                     to the Plan on behalf  of  eligible  employees.  Fixed  profit  sharing
                                     contributions in 2004 amounted to $3,345,879.

                            (ii)     Variable  profit  sharing is comprised of an  additional  annual  profit

2.      Summary of          Use of Estimates
        Significant
        Accounting          The preparation of financial statements in conformity with accounting  principles
        Policies            generally  accepted in the United States of America  requires  management to make
        (Continued)         estimates  and   assumptions   that  affect  the  reported   amounts  of  assets,
                            liabilities,  and  changes  therein,  and  disclosure  of  contingent  assets and
                            liabilities. Actual results could differ materially from those estimates.

                            Risks and Uncertainties

                            The  Plan's  investment  in  Edison   International   Common  Stock  amounted  to
                            approximately  $922,975,000  and  $690,049,000 as of December 31, 2004, and 2003,
                            respectively.  Such  investments  represented  approximately  35  percent  and 32
                            percent  of  the  Plan's  total  assets  as  of  December  31,  2004,  and  2003,
                            respectively.   For  risks  and  uncertainties  regarding  Edison  International,
                            participants  should refer to the December 31, 2004, Forms 10-K and the March 31,
                            2005, Forms 10-Q of Edison International, and affiliate entities as follows:

                            The Plan provides for various funds that hold investment  securities.  Investment
                            securities  are  exposed to various  risks such as  interest  rate,  market,  and
                            credit  risk.  Due to the  level  of  risk  associated  with  certain  investment
                            securities  and the  level of  uncertainty  related  to  changes  in the value of
                            investment  securities,  it is at least reasonably  possible that changes in risk
                            in the near term would materially affect  participants'  account balances and the
                            amounts  reported in Statements of Net Assets Available for Plan Benefits and the
                            Statement of Changes in Net Assets Available for Plan Benefits.

2.      Summary of          The Plan participates in various investment  options that comprise  securities of
        Significant         foreign  companies,  which involve special risks and considerations not typically
        Accounting          associated with investing in U.S.  companies.  These risks include devaluation of
        Policies            currencies, less  reliable  information  about  issuers,  different  securities
        (Continued)         transaction clearance and settlement  practices,  and possible adverse political
                            and economic  developments.  Moreover,  securities of many foreign  companies and
                            their markets may be less liquid and their prices more  volatile than  securities
                            of comparable U.S companies.

                            Investment Valuation and Income Recognition

                            The  Plan's  investments  are  stated  at fair  value or  estimated  fair  value.
                            Investments in mutual funds valued at quoted market prices  represent  units held
                            by the Plan at year end.  Investments  in the common  collective  funds invest in
                            Premixed  Portfolios  and  institutional  funds (see Note 4).  Investments in the
                            common  collective funds are valued at net asset value of shares held by the plan
                            at year-end.  Edison  International  Common Stock is valued at its quoted  market
                            price.  Participant  loans are valued at cost,  which  approximates  fair  value.
                            Purchases and sales of securities  are recorded on a trade-date  basis.  Interest
                            income  is  recorded  on  the  accrual  basis.  Dividends  are  recorded  on  the
                            ex-dividend date.

                            Management  determines  the  collectibility  of  participant  loans on a periodic
                            basis.  This  determination  is made based on the terms of the Plan  document and
                            the related  Plan  policies  and  procedures.  Those  participant  loans that are
                            deemed to be  uncollectible  are  written-off and included as loans in default in
                            the financial  statements and the Form 5500 for financial  reporting  purposes in
                            the year the  determination  is made. For the year ended December 31, 2004, there
                            was approximately $2,275,000 in participant loans deemed to be uncollectible.

9.      Tax Status       The Internal  Revenue Service has determined and informed the Plan Sponsor by a
                         letter dated May 22, 2002,  that the Plan and related trust as amended  through
                         November  29,   2001,   are  designed  in   accordance   with  the   applicable
                         qualification  sections of the Internal  Revenue Code (IRC).  The Plan has been
                         amended  since  receiving  the   determination   letter.   However,   the  Plan
                         administrator  believes  that the Plan,  as amended,  is designed in compliance
                         with the applicable  qualification  requirements  of the IRC. In addition,  the
                         Plan  Administrator  is not aware of any operational  issues that would prevent
                         the continuation of the Plan's qualified tax status.
