                                                                  Exhibit 99.1


          STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER REGARDING
            FACTS AND CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS


I,  Daniel P.  Landguth,  Chairman  and Chief  Executive  Officer of Black Hills
Corporation ("BHC"), state and attest that:

1.   To the best of my knowledge,  based upon a review of the covered reports of
     BHC,  and,  except as corrected  or  supplemented  in a subsequent  covered
     report:

          o    No covered  report  contained  an untrue  statement of a material
               fact as of the end of the period  covered  by such  report (or in
               the case of a report on Form 8-K or definitive  proxy  materials,
               as of the date on which it was filed); and

          o    No covered  report  omitted to state a material fact necessary to
               make  the  statements  in the  covered  report,  in  light of the
               circumstances  under which they were made,  not  misleading as of
               the end of the period covered by such report (or in the case of a
               report on Form 8-K or definitive proxy materials,  as of the date
               on which it was filed).

2.   I have reviewed the contents of this statement with BHC's Audit Committee.

3.   In this statement under oath, each of the following,  if filed on or before
     the date of this statement is a "covered report":

          o    2001 Annual Report on Form 10-K of BHC filed with the Commission;

          o    All  forms  on  Form  10-Q,  all  reports  on  Form  8-K  and all
               definitive  proxy  materials  of BHC  filed  with the  Commission
               subsequent to the filing of the Form 10-K identified above; and

          o    Any amendments to any of the foregoing.

Dated this 12th day of August, 2002.
