                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                     
                                     
            (Reference is made to Notes to Financial Statements
                 included in the Company's Annual Report)


(1)  Management's Statement -

     The financial statements included herein have been prepared by
Northwestern Public Service Company (the Company), without audit, pursuant
to the rules and regulations of the Securities and Exchange Commission.  In
the opinion of the Company, all adjustments necessary for a fair
presentation of the results of operations for the interim periods have been
included.  It is suggested that these financial statements be read in
conjunction with the financial statements and the notes thereto included in
the Company's latest annual report to stockholders.

(2)  Subsidiaries and Principles of Consolidation -

     The consolidated financial statements include the accounts of all
wholly and majority owned or controlled subsidiaries.  All significant
intercompany transactions have been eliminated.

(3)  Allowance for Funds Used During Construction -

     The allowance for funds used during construction includes the costs of
equity and borrowed funds used to finance construction which are
capitalized in accordance with rules prescribed by the FERC.  For the
quarters ended June 30, 1997 and 1996, allowance for equity funds was $597
and $12,568.  For the six months ended June 30, 1997 and 1996, allowance
for equity funds was $30,784 and $48,078.  Allowance for borrowed funds was
$1,330 and $11,145 for the quarters ended June 30, 1997 and 1996, and
$68,520 and $41,409 for the six months ended June 30, 1997 and 1996.

(4)  Change in Accounting Policy for Natural Gas Demand Costs -

     Effective January 1, 1997, the Company changed its method of
accounting for demand costs for natural gas supplies.  Prior to 1997,
demand costs were recognized as incurred which are generally consistent and
stable throughout the course of a normal year.  Beginning January 1, 1997
these costs are being recognized in proportion to natural gas volumes
purchased.  The Company believes that this provides for better matching of
expenses with revenues.  There is no significant effect from this change on
an annual basis, but this change does impact interim reporting periods.  On
a pro forma basis, giving effect to this change, earnings per share would
have been $.16 for the three months ended June 30, 1996 and $.71 for the
six months ended June 30, 1996.

 (5) Reclassifications -

     Certain 1996 amounts have been reclassified to conform to the 1997
presentation.  Such reclassifications had no impact on net income and
common stock equity as previously reported.  Shares outstanding and
earnings per share amounts have been adjusted to reflect the May 1997
stock split.

 (6) Adoption of SFAS 128

     Effective December 31, 1997, the Company will adopt Statement of
Financial Accounting Standards No. 128 (SFAS 128).  SFAS 128 "Earnings Per
Share", establishes new accounting standards for the calculation of
earnings per share.  Adoption of SFAS 128 will not have an effect upon the
Company's current period earnings per share.


              MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION
                         AND RESULTS OF OPERATIONS


     Northwestern Public Service is a diversified energy distribution
company with operations engaged in the propane, electric, and natural gas
industries.  The Company generates and distributes electric energy to
56,000 customers in eastern South Dakota.  It also purchases and
distributes natural gas to 77,000 customers in eastern South Dakota and
central Nebraska.

     Through the acquisitions of Synergy Group Incorporated (Synergy) and
Myers Propane Gas Company (Myers) in 1995 and Empire Energy Corporation
(Energy) and CGI Holdings, Inc. (Coast) in 1996, the Company is engaged in
retail propane distribution business located throughout the United States.
On December 17, 1996, the Company's propane distribution businesses of
Coast, Energy, Myers and Synergy were combined into Cornerstone Propane
Partners, L.P. (Cornerstone), a publicly traded Delaware limited
partnership, formed to acquire and operate these propane businesses and
assets.  The Company through its majority owned subsidiaries retained
initially an effective 2% general partner interest and a 39% subordinated
limited partnership interest in Cornerstone.  A wholly owned subsidiary of
the Company serves as the general partner of Cornerstone and manages and
operates Cornerstone's business.

     The Company's manufacturing operations are comprised of Lucht Inc., a
wholly owned subsidiary that develops, manufactures and markets multi-image
photographic printers and other related equipment.

Weather

     Weather patterns have a material impact on the Company's operating
performance. Because propane and natural gas are heavily used for
residential and commercial heating, the demand for these products depends
heavily upon weather patterns throughout the Company's market areas. With a
larger proportion of its operations related to seasonal propane and natural
gas sales in 1997, the distribution of the Company's quarterly operating
performance will be different than in historical periods. A greater portion
of the Company's future operating income is expected to be recognized in
the first and fourth quarters related to higher revenues from the heating
season which will be partially offset by the change in accounting policy
for natural gas demand costs discussed in Note 4 of Notes to Consolidated
Financial Statements.


RESULTS OF OPERATIONS:

Earnings Comparisons -

     Earnings per share for the quarters ended June 30, 1997 and 1996, were
both $.14.  Earnings per share on a pro forma basis, after giving effect to
the change in accounting for natural gas demand costs discussed in Note 4
would have been $.16 for the quarter ended June 30, 1996.  The decrease in
earnings on a pro forma basis was due to substantially warmer than normal
weather in the Company's propane operating areas offset partially by
improved returns from electric sales.

     Earnings per share for the year to date through June 30, 1997, was
$.69 compared to $.84 for the six months ended June 30, 1996.  Earnings per
share on a pro forma basis, after giving effect to the change in accounting
for natural gas demand costs discussed in Note 4 would have been $.71 for
the six months ended June 30, 1996.  The decrease in earnings on a pro
forma basis was due to substantially warmer than normal weather in the
Company's propane operating areas.  Favorably impacting earnings for the
six months ended were colder weather in the Company's electric and natural
gas operating areas during the first quarter.

Electric and Natural Gas -

     Retail electric revenues and sales both increased by 1% for the three
months ended June 30 as compared to the same period of the prior year.
Natural gas revenues and sales both decreased by 2% for the three months
ended June 30 due to slightly warmer weather as compared to the same period
of the prior year (4% warmer on a weighted average basis).  Natural gas
margins decreased compared to the prior year due to a change in accounting
for natural gas demand costs.  This change in accounting will effect
interim periods but should have no effect on an annual basis.

     Retail electric revenues increased by 1% for the six months ended
while retail sales increased by 3% as compared to the same period of the
prior year.  The smaller increase in revenues reflects improved operating
costs and efficiencies at the Company's base-load generating plants.
Natural gas revenues increased by 8% for the six months ended while sales
increased by 3% as compared to the same period of the prior year.  Natural
gas revenues increased significantly due to substantial increases in
commodity market prices during the winter heating season.  Natural gas
margins decreased compared to the prior year due to a change in accounting
for natural gas demand costs.

Propane -

     Operating revenues from propane for the three months ended June 30
increased from $18.7 million in 1996 to $128.6 million in 1997.  Gallons
also increased from 18.2 million in 1996 to 100.5 million in 1997.
Revenues and gallons both increased due to the acquisitions of two large
retail propane distributors in late 1996 followed by the formation of
Cornerstone in December 1996.  The propane operations in 1997 have been
affected by weather that has been substantially warmer than normal.  The
majority of propane revenues and operating income occur in the first and
fourth quarters when propane is heavily sold for residential and commercial
heating as compared to the second and third quarters which traditionally
are net loss periods in the industry.

     Operating revenues from propane for the six months ended June 30
increased from $60.5 million in 1996 to $349.3 million in 1997.  Gallons
also increased from 57.0 million in 1996 to 255.8 million in 1997.
Revenues and gallons both increased due to the acquisitions and the
formation of Cornerstone in late 1996.  The propane operations for the six
months ended June 30, 1997, have been heavily impacted by weather that has
been 8% warmer than normal.

Manufacturing -

     Manufacturing revenues are related to the Company's investment in
Lucht Inc., a firm that manufactures photographic processing and imaging
equipment used by high volume photo processing laboratories.  Weaker
quarterly sales activity produced lower revenues for the second quarter and
the year-to-date as compared to 1996.  Favorably impacting earnings for
both the three months and six months were improvements in operating
expenses.

Other Income Statement Items -

     Other operating expenses for both the three months and six months
ended June 30 increased in 1997 as compared to 1996 primarily due to the
acquisition of two large retail propane distributors in October and
December 1996.  Other income increased during both the three months and six
months ended June 30 due to higher investment income in 1997 as compared to
1996.  The increase in depreciation reflects the increase in depreciable
propane assets when compared to the same periods of the prior year.  The
increase in interest expense is related to the issuance of $220 million
nonrecourse notes by Cornerstone in December 1996 as part of the
Cornerstone partnership formation.  The increase in interest expense is
partially offset in the second quarter by the redemption of the 8.9% series
general mortgage bonds in March 1997.  The decrease in income taxes is due
to the minority interest effect upon the Company's consolidated net income.

Liquidity and Capital Resources -

     The Company has a high degree of long-term liquidity through the
generation of operating cash flows, the availability of substantial
marketable securities, and a sound capital structure.  In addition, the
Company has adequate capacity for additional financing and has maintained
its liquidity position through favorable bond ratings.

     The Company has generated significant operating cash flows while
continuing to maintain substantial cash and investment balances in the form
of marketable securities.  Cash flows from operating activities during the
six months ended June 30, 1997 and 1996 were $31.2 million and $29.2
million.  The increase was primarily due to increased cash flows from
propane operations.  Cash equivalents and investment securities totaled
$134.6 million and $40.6 million at June 30, 1997 and 1996.  In July 1997
the company retired early the $15 million outstanding of the 8.824% series
general mortgage bonds.

     Working capital and other financial resources are also provided by
lines of credit, which are generally used to support commercial paper
borrowings, a primary source of short-term financing.  At June 30, 1997,
unused short-term lines of credit totaled $32.0 million.  In addition, the
Company's nonregulated businesses maintain nonrecourse credit agreements
with various banks for revolving and term loans.

Capital Requirements -

     The Company's primary capital requirements include the funding of its
energy business construction and expansion programs, the funding of debt
retirements, and the funding of its corporate development and investment
activities.

     The emphasis of the Company's construction activities is to undertake
those projects that most efficiently serve the expanding needs of its
customer base, enhance energy delivery capabilities, expand its current
customer base, and provide for the reliability of energy supply.
Expenditures for construction activities during the six months ended June
30, 1997 and 1996 were $9.6 and $14.8 million.  Included in such
construction activities were nonregulated capital expenditures of $2.0
million and $2.7 million during the six months ended June 30, 1997 and
1996.  Capital expenditures for 1997, excluding propane, are estimated to
be $14.7 million with a large portion of expenditures to be spent on
enhancements of the electric and natural gas distribution systems.
Electric and natural gas related capital expenditures for the years 1997
through 2001 are estimated to be $64.6 million.  Nonregulated maintenance
capital expenditures for 1997 are estimated to be $4.8 million.  Estimated
nonregulated maintenance capital expenditures for the years 1997 through
2001 are estimated to be $18.8 million.

     Capital requirements for the mandatory retirement of long-term debt
will be $6.5 million in 1998, $14.0 million in 1999, $6.5 million in 2000,
and $6.5 million in 2001.

     The Company anticipates that future capital requirements will be met
by significant liquid investments on hand, internally generated cash flows
and available external financing.
