SECTION 4 - MATTERS RELATED TO ACCOUNTANTS AND FINANCIAL STATEMENTS

ITEM 4.01     CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

(a)  Previous Independent Registered Public Accounting Firm
     
     On March 15, 2005, the Minnesota Power and Affiliated  Companies Retirement
     Savings and Stock  Ownership Plan (RSOP)  dismissed  PricewaterhouseCoopers
     LLP   (PricewaterhouseCoopers)   as  its  independent   registered   public
     accounting   firm.   ALLETE,   Inc.,  the  sponsoring   employer  and  plan
     administrator of the RSOP,  continues to engage  PricewaterhouseCoopers  as
     its independent  registered  public accounting firm. The decision to change
     independent registered public accounting firms was approved by the Employee
     Benefit Plans Committee of the RSOP.

     The reports of  PricewaterhouseCoopers  on the financial  statements of the
     RSOP for the years ended  December  31,  2003 and 2002,  did not contain an
     adverse  opinion or  disclaimer  of  opinion,  nor were they  qualified  or
     modified as to uncertainty, audit scope, or accounting principle.

     During the years ended  December 31, 2003 and 2002,  and through  March 15,
     2005, there have been no disagreements with  PricewaterhouseCoopers  on any
     matter  of  accounting   principles  or  practices,   financial   statement
     disclosure,  or auditing scope or procedure,  which  disagreements,  if not
     resolved to the satisfaction of  PricewaterhouseCoopers,  would have caused
     PricewaterhouseCoopers  to make  reference  thereto in their reports on the
     financial statements for such years.

     During the years ended  December 31, 2003 and 2002,  and through  March 15,
     2005,  there were no  "reportable  events," as that term is defined in Item
     304(a)(1)(v) of Regulation S-K.

     A copy of the foregoing disclosures was provided to  PricewaterhouseCoopers
     prior to the date of the filing of this report.  PricewaterhouseCoopers has
     furnished  the RSOP a copy of the letter  addressed to the  Securities  and
     Exchange  Commission  stating  whether or not it agrees with the statements
     above. A copy of  PricewaterhouseCoopers'  letter, dated March 18, 2005, is
     filed as Exhibit 16 to this Form 8-K.

(b)  New Independent Registered Public Accounting Firm

     On March 15, 2005,  the RSOP  engaged the  professional  audit  services of
     Reilly,  Penner & Benton  LLP  (Reilly,  Penner & Benton),  an  independent
     registered  public  accounting firm, to audit its financial  statements for
     the year ended December 31, 2004.

     During the years ended  December 31, 2003 and 2002,  and through  March 15,
     2005,  RSOP did not consult with Reilly,  Penner & Benton  regarding any of
     the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation
     S-K.
