ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

      In the Form 8-K dated  April 22,  1997 and  filed on April 28,  1997,  the
Company disclosed that the client-auditor  relationship  between the Company and
Deloitte & Touche LLP, would be terminated  effective with the completion of the
December 31, 1996 audit of the Company's consolidated financial statements. That
work has been  completed and their  opinions have been included in the Company's
transition  report on Form 10-K for the four month  period  ended  December  31,
1996,  that was filed on July 21, 1997,  and in the New Century  Energies,  Inc.
Form 8-K dated  August 1,  1997.  Additionally,  as  previously  disclosed,  the
Company  announced its new  certifying  accountants,  Arthur  Andersen LLP, will
serve as  independent  accountants  for the calendar year 1997.  The decision to
change accountants was made in conjunction with the then anticipated merger with
Public Service  Company of Colorado,  which was effective on August 1, 1997, and
was recommended by the Audit Committee and approved by the Board of Directors.

      Deloitte & Touche  LLP's  reports on the  Company's  financial  statements
during  the two most  recent  fiscal  years  and the  transition  period  ending
December 31, 1996,  preceding  the date hereof  contained no adverse  opinion or
disclaimer  of opinion,  and was not  qualified  or modified as to  uncertainty,
audit scope, or accounting principles.

      During the last two fiscal years,  the transition  period ending  December
31, 1996, and the  subsequent  period  preceding the date hereof,  there were no
disagreements  between the  Company and  Deloitte & Touche LLP on any matters of
accounting principles or practices,  financial statement disclosure, or auditing
scope or procedure, which disagreements,  if not resolved to the satisfaction of
Deloitte  & Touche  LLP,  would  have  caused  Deloitte  & Touche  LLP to make a
reference to the subject  matter of the  disagreements  in  connection  with its
reports.

      None of the  "reportable  events"  described  under  Regulation  S-K, Item
304(a)(1)(v), occurred within the Company's two most recent fiscal years and any
subsequent interim periods preceding the date hereof.

      During the last two fiscal years,  the transition  period ending  December
31, 1996, and the subsequent  period preceding the date hereof,  the Company did
not consult Arthur Andersen LLP regarding any of the matters or events set forth
in Item 304(a)(2)(i) and (ii) of Regulation S-K.
