             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Participants and Administrator of the
Minnesota Power and Affiliated Companies
Retirement Savings and Stock Ownership Plan


We have audited the accompanying  statement of net assets available for benefits
of the Minnesota  Power and Affiliated  Companies  Retirement  Savings and Stock
Ownership Plan (the "Plan") as of December 31, 2004,  and the related  statement
of changes in net assets  available for benefits for the year 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 audit.  The  financial  statements  of the Plan as of December 31, 2003 were
audited  by other  auditors  whose  report  dated  May 28,  2004,  expressed  an
unqualified opinion on those statements.

We conducted our audit of these  statements 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.  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,  and
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 benefits of the Plan as of
December 31, 2004, and the changes in its net assets  available for benefits for
the year then ended in conformity with accounting  principles generally accepted
in the United States of America.

Our audit was  conducted  for the  purpose  of  forming  an opinion on the basic
financial statements taken as a whole. The supplemental  schedules,  Schedule of
Assets (Held at End of Year) - December 31, 2004,  Schedule of Assets  (Acquired
and  Disposed of Within  Year) - Year Ended  December  31, 2004 and  Schedule of
Reportable  Transactions  - Year Ended  December 31, 2004, are presented for the
purpose  of  additional  analysis  and are  not a  required  part  of the  basic
financial   statements  but  are  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.  These  supplemental
schedules are the  responsibility of the Plan's  management.  These supplemental
schedules have been subjected to the auditing  procedures  applied in the audits
of the basic financial  statements and, in our opinion, are fairly stated in all
material  respects  in  relation to the basic  financial  statements  taken as a
whole.

NOTE 1 - DESCRIPTION OF THE PLAN

The  Minnesota  Power and  Affiliated  Companies  Retirement  Savings  and Stock
Ownership  Plan  (RSOP or  Plan) is a  contributory  defined  contribution  plan
subject to the  provisions  of the Employee  Retirement  Income  Security Act of
1974, as amended (ERISA),  and qualifies as an employee stock ownership plan and
profit sharing plan. At December 31, 2004, there were 1,856  participants in the
RSOP.  Participating  affiliated  companies  (collectively,  the  Companies)  at
December 31, 2004, included:

    - ALLETE, Inc. (ALLETE, or Company)
    - Minnesota Power (an operating division of ALLETE)
    - Superior Water, Light and Power Company
    - Enventis Telecom, Inc.
    - MP Affiliate Resources, Inc.

The RSOP provides eligible employees of the Companies an opportunity to save for
retirement by electing to make  before-tax and after-tax  contributions  through
payroll   deduction,   and  directing  the  contributions  into  various  401(k)
investment options. (See Participant Investment Options.) The RSOP also provides
eligible  employees of the Companies employee stock ownership benefits in ALLETE
common stock (Common Stock).

BASIS OF PRESENTATION

Participant funds represent the participants' 401(k) investment funds and shares
allocated  to  participants  in the ALLETE  RSOP Stock Fund.  Unallocated  funds
represent  unallocated  shares to be  allocated to the ALLETE RSOP Stock Fund in
the future.

ADMINISTRATION

The  Plan is  administered  for the  Companies  by the  Employee  Benefit  Plans
Committee (Committee).  The mailing address of the Committee is 30 West Superior
Street, Duluth,  Minnesota 55802-2093.  The Committee consists of 10 members who
were  appointed by the Board of Directors of ALLETE.  The Board of Directors has
the power to  remove  members  of the  Committee  from  office.  Members  of the
Committee receive no compensation for their services with respect to the Plan.

The  responsibility  of the Committee  includes the  determination of compliance
with the Plan's  eligibility  requirements,  as well as, the  administration and
payment  of  benefits  in a manner  consistent  with  the  terms of the Plan and
applicable law. The Committee has the authority to establish,  modify and repeal
policies and  procedures as it may deem necessary to carry out the provisions of
the Plan. The Committee also has the authority to designate persons to carry out
fiduciary responsibilities (other than trustee responsibilities) under the Plan.
The  Committee  has the power to appoint an  investment  manager or managers (as
defined by ERISA),  attorneys,  accountants  and such other  persons as it shall
deem necessary or desirable in the  administration  of the Plan.  Administration
fees and  expenses  of  agents,  outside  experts,  consultants  and  investment
managers are paid by the  Companies or the Plan.  The Plan charges  participants
who take  participant  loans or use the Plan's  self-managed  brokerage  account
feature for expenses relating to such loans or accounts.

American  Express  Retirement  Services,  a service  group of  American  Express
Financial  Advisors  Inc.,  and American  Express Trust  Company  (collectively,
American  Express) is the service  provider  for the Plan  handling  participant
recordkeeping  and  certain  other  administrative  responsibilities.   American
Express  allows  the Plan to value  accounts  daily  and  provides  participants
flexibility  with  regard to  investment  of their  account  balances.  American
Express Trust Company  (Trustee),  which is located at 994 AXP Financial Center,
Minneapolis,  Minnesota,  55474-0507,  is the trustee for the Plan.  The Trustee
carries $25 million of blanket  bond  insurance  and $5 million of  professional
liability insurance.

EMPLOYEE STOCK OWNERSHIP BENEFITS - ALLETE RSOP STOCK FUND

ALLETE  sponsors a leveraged  employee  stock  ownership  plan (ESOP) within the
RSOP.  Eligible  employees  of the  Companies  receive  Common  Stock  ownership
benefits in the ALLETE RSOP Stock Fund.  These benefits are primarily  funded by
payments  made by the Plan on two loans (see First  Suspense  Account and Second
Suspense Account). Shares of Common Stock are allocated to eligible employees as
provided by the Plan (see Basic Account,  Special Account,  Partnership Account,
Bargaining  Unit  Account  and  Matching  Account).  The shares of Common  Stock
allocated  to a  participant's  ALLETE  RSOP  Stock Fund come from the First and
Second Loan  Suspense  Accounts,  as determined  by ALLETE.  Each  participant's
account  value,  however,  is  determined  on a unit basis and  consists of both
Common Stock and cash.  (See Note 5.) The unit value is adjusted  each  business
day to reflect investment results including cash.

With the exception of a  participant's  Basic  Pre-1989  Account,  dividends are
automatically  reinvested  in Common  Stock held in the ALLETE  RSOP Stock Fund.
Participants with a Basic Pre-1989 Account may make an election, at any time, to
receive  dividends paid on their Basic Pre-1989  Account in cash. Units within a
participant's  Basic  Pre-1989  Account can be withdrawn at any time,  while all
other units within a participant's  ALLETE RSOP Stock Fund can be withdrawn when
the participant  reaches age 59 1/2 or terminates  employment.  Participants may
transfer all or any part of their ALLETE RSOP Stock Fund  excluding  their Basic
Pre-1989 Account to other 401(k) investment options at any time.

FIRST  SUSPENSE  ACCOUNT.  In 1989 the RSOP was amended to establish a leveraged
First Suspense  Account.  The First  Suspense  Account  originally  consisted of
633,849  shares of Common  Stock  (422,566  shares  adjusted  for stock  splits)
purchased  for the benefit of eligible  Plan  participants  with proceeds from a
15-year $16.5  million loan (First Loan) with a variable  interest rate equal to
LIBOR plus 1.75% fixed for 30, 60, 90 or 180 days at ALLETE's option.  On August
21, 2004, this loan was paid in full. The First Suspense  Account  provided that
as the  First  Loan is  repaid,  shares of  Common  Stock in the First  Suspense
Account were  allocated  to each  participant's  various  ALLETE RSOP Stock Fund
accounts based on the applicable  allocation  methods as defined in the Plan and
summarized  below.  The remaining  61,704 shares of Common Stock related to this
loan were allocated in 2004.

                           ALLETE 2004 RSOP Form 11-K                          6



SECOND  SUSPENSE  ACCOUNT.  The RSOP was again  amended in 1990 to  establish  a
leveraged  Second Suspense  Account and borrow an additional $75 million (Second
Loan) to acquire 2,830,188 newly issued shares of Common Stock (1,886,792 shares
adjusted for stock splits) from ALLETE for the benefit of eligible participants.
Under this  amendment,  active  participants  with a Basic Account are allocated
shares to their  Special  Account with a value at least equal to: (a)  dividends
payable on shares  held by those  participants  in the Plan and (b) tax  savings
generated from the deductibility of dividends paid on all shares of Common Stock
held in the RSOP as of August 4, 1989. In accordance  with this  amendment,  the
trustee issued a promissory  note to ALLETE for $75 million at a 10.25% interest
rate with a term not to exceed 25 years.  The Second  Suspense  Account may also
provide for other allocation types as determined by the Company.

BASIC  ACCOUNT.  Participants'  Basic Accounts  received  shares of Common Stock
purchased with incremental investment tax credit contributions and payroll-based
tax credit  contributions.  Contributions  to the  participants'  Basic Accounts
ceased after 1986.

SPECIAL ACCOUNT.  For the years 1985 through 1989, the Companies  received a tax
deduction  for cash  dividends  paid to  participants  on ALLETE RSOP Stock Fund
shares in their Basic  Account.  The  Companies  contributed  to the ALLETE RSOP
Stock Fund an amount equal to the  estimated  income tax benefit of the dividend
deduction associated with eligible shares in the Basic Account. Shares of Common
Stock  purchased with these  contributions  were allocated to the  participants'
Special Account.

PARTNERSHIP ACCOUNT.  Since 1989 partnership  allocations have been made to each
nonunion participant's Partnership Account based on the ratio of a participant's
annual compensation to the annual compensation of all eligible participants.  If
the value of the shares credited to a participant's  Partnership Account is less
than  3.5  percent  of  the  participant's  eligible  annual  compensation,  the
Companies will contribute additional shares to make up the difference.

BARGAINING  UNIT ACCOUNT.  Quarterly  non-elective  allocations  are made to the
ALLETE  RSOP  Stock  Fund  equal to 0.75  percent  of each  union  participant's
eligible  compensation.  Effective  February 1, 2004, the allocation  percentage
increased to 1.0 percent of each union participant's eligible compensation.

MATCHING  ACCOUNT.  Quarterly  matching  allocations are made to the ALLETE RSOP
Stock Fund equal to 50 percent of each nonunion  participant's 401(k) before-tax
contributions,  disregarding  contributions  in  excess  of  4  percent  of  the
participant's  periodic pay for the period (8 percent for Enventis Telecom, Inc.
employees).


CONTRIBUTIONS

PARTICIPANT CONTRIBUTIONS to the Plan consist of the following:

    - BEFORE-TAX  CONTRIBUTIONS.  Before-tax  contributions  consist  of  salary
      reduction contributions, results sharing contributions and flexible dollar
      contributions.  Total  before-tax  contributions  in 2004 could not exceed
      $13,000 for  participants  less than age 50 or $16,000 for participants at
      least age 50, as permitted  under Section  401(k) of the Internal  Revenue
      Code (Code).

      - SALARY REDUCTION CONTRIBUTIONS. Salary reduction contributions are equal
        to  an  amount  the  participant  has  elected  to  reduce  his  or  her
        compensation pursuant to a salary reduction agreement.

      - RESULTS SHARING  CONTRIBUTIONS.  Results sharing contributions are equal
        to the portion (up to 100  percent)  of the  Results  Sharing  Award the
        participant irrevocably agrees to forgo and that, pursuant to the ALLETE
        Results Sharing Program, would otherwise be paid to the participant.

      - FLEXIBLE DOLLAR  CONTRIBUTIONS.  Nonunion participants may make flexible
        dollar  contributions  equal  to the  portion  (up to  100  percent)  of
        flexible dollars the participant  irrevocably  agrees to forgo and that,
        pursuant  to the  Minnesota  Power  and  Affiliated  Companies  Flexible
        Compensation Plan, would otherwise be used for other benefits or paid to
        the   participant.   Effective   January   1,  2005,   flexible   dollar
        contributions are no longer eligible for deferral into the Plan.

      - VOLUNTARY CONTRIBUTIONS (AFTER-TAX  CONTRIBUTIONS).  Each participant is
        also  allowed  to make  voluntary  after-tax  contributions  to the Plan
        through  payroll  deductions.  Total voluntary  contributions  made by a
        participant   shall  not  exceed  25   percent   of  the   participant's
        compensation per pay period.

      - ROLLOVERS.  Contributions  by  participants  may  also be  made  through
        rollovers from other qualified plans.

EMPLOYER  CONTRIBUTIONS  for each year are paid to the Trustee either in cash or
in Common Stock.  Expenses incurred in discretionary  activities relating to the
design,  formation  and  modification  of the Plan  (commonly  characterized  as
"settlor" functions) are paid by the Companies.


VESTING AND FORFEITURE ACCOUNT

As of July 1, 2001, all  contributions  plus actual  earnings  thereon are fully
vested and nonforfeitable.  A forfeiture  account,  which consists of previously
forfeited nonvested  accounts,  totaled $27,000 at December 31, 2004 ($33,000 at
December  31,  2003) and is invested in American  Express  Trust Income Fund II.
Dollars from the forfeiture account will be used to reduce future Plan expenses.


DISTRIBUTIONS AND WITHDRAWALS

A participant may elect,  at any time, to receive in cash future  dividends paid
on Common Stock shares in their  ALLETE RSOP Stock Fund Basic  Pre-1989  Account
and ALLETE Stock Fund.

Prior to termination,  a participant may withdraw,  at any time, all or any part
of their:
    - Plan accounts, if the participant has attained age 59 1/2;
    - After-tax account, regardless of the participant's age; or
    - Pre-1989 Basic Account, regardless of the participant's age.

When participants  terminate  employment,  become disabled or die, they or their
beneficiaries may elect to receive all or any part of their Plan accounts.

TRANSFERS  TO  RETIREMENT  PLANS.  Upon  retirement,  participants  may elect to
transfer  their Plan  account  balances to the  Minnesota  Power and  Affiliated
Companies Retirement Plan A or Plan B, if the participant is receiving a benefit
from one of these retirement  plans. The amount of transfers to these retirement
plans totaled $6,905,000 for 2004.

LOAN  PROGRAM.  The Plan  allows  participants  to borrow  money from their Plan
accounts.  The maximum amount a participant may borrow is equal to the lesser of
(a) the  participant's  aggregate  before-tax  account,  after-tax  account  and
rollover account  balances,  (b) 50 percent of their total Plan balance,  or (c)
$50,000.  The loans may not be less than  $1,000.  The loans are for terms up to
five years for a general  purpose  loan and ten years for the  acquisition  of a
primary residence. A fixed interest rate of the prime rate plus 1 percent on the
first day of the month that the loan is  originated is charged until the loan is
repaid. As loans are repaid, generally through payroll deductions, principal and
interest  amounts  are  redeposited  into  the   participant's   Plan  accounts.
Participants are required to pay a $50 loan application fee to cover the cost of
processing the loan.


PLAN TERMINATION

The  Companies  reserve  the  right to  reduce,  suspend  or  discontinue  their
contributions to the Plan, at any time, or to terminate the Plan in its entirety
subject to the provisions of ERISA and the Code. If the Plan is terminated,  all
of the account  balances of the  participants  will be distributed in accordance
with the terms of the Plan.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

The Plan uses the accrual basis of accounting and, accordingly,  reflects income
in the year earned and  expenses  when  incurred.  Common  stock and mutual fund
investments  are  reported  at their fair value based on quoted  market  prices.
Collective fund  investments are reported at net asset value which  approximates
fair  value.  Participants'  loans are  reported at  estimated  fair value which
represents outstanding principal and any related accrued interest.

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States of America requires  management to make
estimates  and  assumptions   that  affect  the  reported   amounts  of  assets,
liabilities  and  changes  therein,  and  disclosure  of  contingent  assets and
liabilities at the date of the financial statements. Actual results could differ
from those estimates.

The Plan  presents,  in the  statement  of changes in net assets  available  for
benefits,  the  net  appreciation  (depreciation)  in  the  fair  value  of  its
investments  which  consists  of  the  realized  gains  or  losses  on  disposed
investments and the unrealized appreciation  (depreciation) on those investments
owned at year end.

The Plan invests in various  funds that are a combination  of stocks,  bonds and
other investment securities.  Investment securities are exposed to various risks
such as  interest  rate,  market  and  credit  risks.  Due to the  level of risk
associated  with  certain  investment  securities,  it  is at  least  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 statement of net assets available for benefits.


NOTE 3 - ALLETE SPIN-OFF AND REVERSE STOCK SPLIT

On September  20, 2004,  ALLETE spun off ADESA,  Inc.  (ADESA),  its  Automotive
Services business, by distributing to ALLETE shareholders all of ALLETE's shares
of ADESA common stock.  One share of ADESA common stock was distributed for each
outstanding  share of ALLETE  common  stock held at the close of business on the
September  13,  2004,  record  date.  Also,  on  September  20,  2004,  ALLETE's
one-for-three  reverse  common  stock split became  effective.  All common share
amounts have been adjusted for all periods to reflect the one-for-three  reverse
stock split.

Participants  in the ALLETE RSOP Stock Fund and the ALLETE Stock Fund received a
pro rata share of ADESA  common stock based on the  unitization  formula used to
determine a participant's  equivalent number of ALLETE shares on the date of the
spin-off.  The ADESA RSOP Stock Fund and the ADESA Stock Fund (ADESA Funds) were
established  to capture the ADESA shares  received in this  spin-off and are not
investment fund options. Participants may transfer out of the ADESA Funds at any
time.  The  decision to transfer  out of either of the ADESA Funds  results in a
sale of ADESA common  stock,  but will not result in a purchase of ALLETE common
stock,  unless the  participant  chooses to  transfer  those funds to the ALLETE
Stock Fund.  Beginning in  September  2005,  an  independent  trustee,  hired by
ALLETE,  is  expected to start  selling any  remaining  ADESA  common  stock and
purchasing  ALLETE common stock according to the  requirements of the RSOP. Once
all the ADESA  common  stock has been  sold,  and ALLETE  common  stock has been
purchased,  remaining  participant balances in the ADESA RSOP Stock Fund and the
ADESA Stock Fund will be transferred to the corresponding ALLETE RSOP Stock Fund
and the ALLETE Stock Fund.

As a result of the  September  2004  spin-off of ADESA,  the RSOP  received  3.3
million  shares of ADESA common stock  related to unearned ESOP shares that have
not been  allocated  to  participants.  The RSOP was  required to sell the ADESA
common  stock and use the proceeds to purchase  ALLETE  common stock on the open
market. Under the direction of an independent trustee, at December 31, 2004, the
RSOP had sold all of these ADESA  shares  which  resulted  in total  proceeds of
$65.9 million and had used $35.6 million of the proceeds to purchase 1.0 million
shares of ALLETE common stock during the fourth quarter of 2004. (See Note 7.)

NOTE 4 - FEDERAL INCOME TAX STATUS

A favorable  determination  letter dated March 23, 2004,  was obtained  from the
Internal  Revenue  Service  stating  that the  RSOP,  as  amended  and  restated
effective  January 1, 2002,  qualified as an employee stock ownership plan and a
profit sharing plan under Section 401(a) of the Code.

The Plan has  subsequently  been amended and the Committee  continues to believe
that the Plan is currently  designed and being  operated in compliance  with the
applicable  requirements of the Code.  Therefore,  no provision for income taxes
has been included in the Plan's financial statements.

The Plan  received a private  letter ruling from the Internal  Revenue  Service,
dated November 23, 2004,  which allowed the Plan until May 25, 2006, to complete
the sale of 3.3 million  shares of  unallocated  ADESA  common stock and use the
proceeds to purchase unallocated ALLETE common stock. (See Notes 3 and 7.)

NOTE 6 - REPAYMENT OF LOANS

The Trustee repays principal and interest on the First Loan and Second Loan with
dividends  paid on the shares of Common Stock in each suspense  account and with
certain employer  contributions to the Plan. The shares of Common Stock acquired
by the  Trustee  are held in the First  Suspense  Account  and  Second  Suspense
Account,  and allocated to the accounts of Plan  participants  as the First Loan
and Second Loan are repaid.

The First Loan was obtained from a third party lender and  guaranteed by ALLETE.
On August 21, 2004,  the remaining  principal  payment of $1,364,000 was paid in
full and 61,704 unallocated shares of Common Stock in the Plan, formerly pledged
as collateral, were released for allocation to participants.

The Second Loan was  obtained  from  ALLETE.  There were  2,001,505  unallocated
shares of Common Stock in the Plan pledged as  collateral  at December 31, 2004.
Prepayments can be made without penalty. The lender has no rights against shares
that are allocated under the Plan.
