     Re:  NWPS CAPITAL FINANCING I

Ladies and Gentlemen:

               We have acted as special Delaware counsel for Northwestern Public
Service Company, a Delaware corporation ("Northwestern"), and NWPS Capital
Financing I, a Delaware business trust (the "Trust"), in connection with the
matters set forth herein.  At your request, this opinion is being furnished to
you.

               For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

               (a)  The Certificate of Trust of the Trust, dated as of June 19,
1995 (the "Certificate"), as filed in the office of the Secretary of State of
the State of Delaware (the "Secretary of State") on June 19, 1995;

               (b)  The Declaration of Trust of the Trust, dated as of June 19,
1995, between Northwestern and the trustees of the Trust named therein;

               (c)  Amendment No. 1 to the Registration Statement (the
"Registration Statement") on Form S-3, including a preliminary prospectus (the
"Prospectus"), and a preliminary prospectus supplement (the "Prospectus
Supplement") relating to the __% Trust Preferred Capital Securities of the Trust

representing preferred undivided beneficial interests in the assets of the Trust
(each, a "Preferred Security" and collectively, the "Preferred Securities"), as
proposed to be filed by Northwestern, the Trust and others as set forth therein
with the Securities and Exchange Commission on July 27, 1995;

               (d)  A form of Amended and Restated Declaration of Trust of the
Trust, to be entered into among Northwestern, the trustees of the Trust named
therein, and the holders, from time to time, of undivided beneficial interests
in the assets of the Trust (including Exhibit A thereto) (the "Declaration"),
attached as an exhibit to the Registration Statement; and

               (e)  A Certificate of Good Standing for the Trust, dated July
27, 1995, obtained from the Secretary of State.

               Initially capitalized terms used herein and not otherwise defined
are used as defined in the Declaration.

               For purposes of this opinion, we have not reviewed any documents
other than the documents listed in paragraphs (a) through (e) above.  In
particular, we have not reviewed any document (other than the documents listed
in paragraphs (a) through (e) above) that is referred to in or incorporated by
reference into the documents reviewed by us.  We have assumed that there exists
no provision in any document that we have not reviewed that is inconsistent with
the opinions stated herein.  We have conducted no independent factual
investigation of our own but rather have relied solely upon the foregoing
documents, the statements and information set forth therein and the additional
matters recited or assumed herein, all of which we have assumed to be true,
complete and accurate in all material respects.

               With respect to all documents examined by us, we have assumed (i)
the authenticity of all documents submitted to us as authentic originals, (ii)
the conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

               For purposes of this opinion, we have assumed (i) that the
Declaration constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Declaration and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in

paragraph 1 below, the due organization or due formation, as the case may be,
and valid existence in good standing of each party to the documents examined by
us under the laws of the jurisdiction governing its organization or formation,
(iii) the legal capacity of natural persons who are parties to the documents
examined by us, (iv) that each of the parties to the documents examined by us
has the power and authority to execute and deliver, and to perform its
obligations under, such documents, (v) the due authorization, execution and
delivery by all parties thereto of all documents examined by us, (vi) the
receipt by each Person to whom a Preferred Security is to be issued by the Trust
(collectively, the "Preferred Security Holders") of a Preferred Security
Certificate for such Preferred Security and the payment for the Preferred
Security acquired by it, in accordance with the Declaration and the Registration
Statement, and (vii) that the Preferred Securities are issued and sold to the
Preferred Security Holders in accordance with the Declaration and the
Registration Statement.  We have not participated in the preparation of the
Registration Statement and assume no responsibility for its contents.

               This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto.  Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder which are currently in effect.

               Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

               1.   The Trust has been duly created and is validly existing in
good standing as a business trust under the Business Trust Act.

               2.   The Preferred Securities will represent valid and, subject
to the qualifications set forth in paragraph 3 below, fully paid and
nonassessable undivided beneficial interests in the assets of the Trust.

               3.   The Preferred Security Holders, as beneficial owners of the
Trust, will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General

Corporation Law of the State of Delaware.  We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Declaration.

               We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  We also
consent to Schiff Hardin & Waite's relying as to matters of Delaware law upon
this opinion in connection with an opinion to be rendered by it in connection
with the Registration Statement.  In addition, we hereby consent to the use of
our name under the heading "Legal Matters" in the Prospectus Supplement and
"Legal Opinions" in the Prospectus.  In giving the foregoing consents, we do not
thereby admit that we come within the category of Persons whose consent is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Securities and Exchange Commission thereunder.  Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.

                                        Very truly yours,


                                        /s/ Richards, Layton & Finger
