                          REPORT  OF  INDEPENDENT  PUBLIC  ACCOUNTING  FIRM

                          ----------------------------

To  the  Retirement  Board  and  Participants  in  the
Green  Mountain  Power  Corporation
     Employee  Savings  and  Investment  Plan  and  Trust

We  have audited the accompanying statements of net assets for benefits of Green
Mountain  Power  Corporation Employee Savings and Investment Plan and Trust (the
"Plan")  as of December 31, 2003 and 2002, and the related statements of changes
in  net assets available for benefits for the years then ended.  These financial
statements  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 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.  An audit includes
examining,  on  a test basis, evidence supporting the amounts and disclosures in
the  financial  statements.  An  audit  also  includes  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,  such  financial  statements  present  fairly, in all material
respects,  the net assets available for plan benefits of the Plan as of December
31,  2003 and 2002 and the changes in net assets available for plan benefits for
the year then ended, in conformity with accounting principles generally accepted
in  the  United  States  of  America.

Our  audits  were  made  for  the  purpose  of  forming  an opinion on the basic
financial  statements  taken  as  a whole.  The supplemental schedules of assets
(held at end of year) 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 is the responsibility of the Plan's management.
Such 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.

     General
     -------
     The Plan is a defined contribution plan established by Green Mountain Power
Corporation.  The  Plan  covers  substantially  all full-time employees of Green
Mountain  Power  Corporation  (the  Company).

     The Company's Retirement Board is the Plan Administrator with the authority
to  control and manage the operation and administration of the Plan.  The Plan's
assets  are  held  by  the  Trustee  of  the  Plan, which invests cash received,
including interest and dividend income, and makes distributions to participants.
The  Plan is subject to the provision of the Employee Retirement Income Security
Act  of  1974  (ERISA).

     Contributions
     -------------
     Each  year,  participants  may  contribute  up  to  15%  of  pretax  annual
compensation,  as  defined  by  the  Plan.  The  Company  contributes a matching

administrative  expenses.  Allocations  are  based  on  participant  earnings or
account balances, as defined.  The benefit to which a participant is entitled is
the  benefit  that can be provided from the participant's vested account, net of
applicable  Federal  tax.

NOTE  1     PLAN  DESCRIPTION  (continued)
      5  years or up to 30 years for the purchase of a principal residence.  The
loans  are secured by the balance in the participant's account and bear interest
at  the  Trustee's  prime  rate.  Principal and interest is paid ratably through
monthly  payroll  deductions.

     Payment  of  Benefits
     ---------------------

participant  may  elect  to  receive  either a lump-sum amount or to purchase an
annuity  equal  to  the value of the participant's vested interest in his or her
account.  For  termination  of  service  due to other reasons, a participant may
receive  the  value  of  the vested interest in his or her account as a lump-sum
distribution.

NOTE  2     SUMMARY  OF  ACCOUNTING  POLICIES

     Basis  of  Accounting
     ---------------------
     The  financial  statements  of  the  Plan  are  prepared in accordance with
accounting  principles  generally  accepted  in  the  United  States of America.

     Use  of  Estimates
     ------------------
     The  preparation  of  financial  statements  in  conformity  with generally
accepted accounting principles requires the Plan Administrator to make estimates
and  assumptions  that affect the reported amounts of assets and liabilities and
disclosure  of  contingent  assets  and liabilities at the date of the financial
statements.  Actual  results  could  differ  from  those  estimates.

     The  Plan  utilizes  various investment instruments, including mutual funds
and  investment  contracts.  Investment  securities,  in general, are exposed to
various  risks,  such  as  interest rate, credit, and overall market volatility.
Due  to  the  level of risk associated with certain investment securities, it is
reasonably  possible  that  changes  in the values of investment securities will
occur in the near term and that such changes could materially affect the amounts
reported  in  the  financial  statements.

     Investment  Valuation  and  Income  Recognition
     -----------------------------------------------
     The  Plan's  investments  are  stated  at fair value.  Shares of registered
investment companies are valued at quoted market prices, which represent the net
asset value of shares held by the Plan at year-end.  The Company stock is valued
at  its  quoted  market  price.  Participant  loans  are  stated  at cost, which
approximates  fair  value.

     Purchases  and  sales  of  securities  are  recorded on a trade-date basis.
Interest  income is recorded on an accrual basis.  Dividends are recorded on the
ex-dividend  date.

     Management  fees and operating expenses charged to the Plan for investments
in the mutual funds are deducted from income earned on a daily basis and are not
separately  reflected.  Consequently, management fees and operating expenses are
reflected  as  a  reduction  of  investment  return  for  such  investments.

     Payment  of  Benefits
     ---------------------
     Benefit  payments  are  recorded  when  paid.

                         December  31,  2003

     Administrative  Expenses
     ------------------------
     Administrative expenses of the Plan are paid by the Plan as provided in the
Plan  document.

NOTE  3     RELATED  PARTY  TRANSACTIONS

     The  Plan's investments were held in trust by UMB Bank, N.A. and managed by
Cigna  for  the  year  ended  December 31, 2003.  During 2004, UMB Bank sold its
employee  benefit  accounts,  including  the  Plan,  to Marshall & Illsley Trust
Company.  Prudential  Financial, Inc. acquired the retirement business of CIGNA,
on  April  1,  2004.  The Plan's administrative expenses represent fees paid for
these  services  and  qualify as party-in-interest transactions.  Automatic Data
Processing,  Inc. provides payroll processing for the Company and qualifies as a
party-in-interest,  however  the  Company  pays  for  the  cost  of the services
directly.

     At  December  31,  2003 and 2002, the Plan held 152,181 and 182,163 shares,
respectively,  of  common  stock  of  Green  Mountain  Power  Corporation,  the
sponsoring  employer,  with  a  cost  basis  of  $3,125,119  and  $3,740,816,
     respectively.  During  the  year ended December 31, 2003, the Plan recorded
dividend  income  of  $93,069.

NOTE  4     PLAN  TERMINATION

     Although  it  has not expressed any intention to do so, the Company has the
right  under  the Plan to discontinue contributions or terminate the Plan at any
time,  subject  to  provisions  of  ERISA.

NOTE  5     INVESTMENTS

     Investments  that  represent  5% or more of the Plan's net assets available

NOTE  6     TAX  STATUS

     The  Internal  Revenue Service has determined and informed the Company by a
letter  dated  October  8,  2002,  that the Plan is qualified under the Internal
Revenue  code (IRC) section 401(a) and the trust is tax-exempt under IRC 501(a).
The Plan has been amended since receiving the determination letter, however, the
Plan  administrator  and  the  Plan's  tax counsel believe the Plan is currently
designed  and  operated within the terms of the Plan and should remain qualified
under  the  applicable  provisions  of  the  IRC.
