               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
Corporation (the Corporation), without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission.  In the opinion
of the Corporation, 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 Corporation's latest
annual report to shareholders.

(2)  Subsidiaries and Principles of Consolidation -

The accompanying consolidated financial statements include the accounts of the
Corporation and all wholly, majority-owned, and controlled subsidiaries, 
including CornerStone Propane Partners, L.P. (NYSE:CNO), the nation's fourth
largest retail propane distributor; Blue Dot Services, Inc., a national
provider of air conditioning, heating, plumbing and related services (HVAC),
and Expanets, Inc., a national provider of integrated communication and data
solutions and network services.  All significant intercompany balances and 
transactions have been eliminated from the consolidated financial statements. 
The Corporation's regulated businesses are subject to various state and federal
agency regulation.  The public unitholders' interest in CornerStone's net 
assets subsequent to the Partnership Formation is reflected as minority
interests in the consolidated financial statements.  Equity interests of the
former owners of companies acquired by Blue Dot. and Expanets who continue to
hold an interest in Blue Dot. and Expanets are also reflected as minority 
interests in the consolidated financial statements.

(3)  Comprehensive Income -

In 1998, the Corporation adopted SFAS No. 130 'Reporting Comprehensive Income.'
This statement requires the reporting of comprehensive income in addition to 
net income from operations. Comprehensive income is a more inclusive financial
reporting methodology that includes disclosure of certain financial information
that historically has not been recognized in the calculation of net income.
Comprehensive income for the three months ended March 31, 1999 and 1998, was
$15.2 million and $9.4 million.

(4)  Segment Information -

In 1998, the Corporation adopted Statement of Financial Accounting Standards
No. 131 (SFAS 131), 'Disclosures About Segments of an Enterprise and Related 
Information,' which requires the reporting of certain financial information by
business segment. For the purpose of providing segment information, the
Corporation's principal business segments are its electric, natural gas,
retail propane, wholesale propane, HVAC and communications operations.  All
other includes other service businesses, the results of manufacturing 
operations (only in 1998), activities and assets of the parent, any reconciling
or eliminating amounts and amortization of purchase accounting adjustments 
related to the acquisitions of HVAC and communication companies.
The accounting policies of the operating segments are the same as the parent
except that the parent allocates some of its operating expenses and interest
expense to the operating segments according to a methodology designed by 
management for internal reporting purposes and involves estimates and 
assumptions.  Financial data for the business segments are as follows

(5)  New Accounting Standards -

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 (SFAS 133), "Accounting for
Derivative Instruments and Hedging Activities." The Statement establishes 
accounting and reporting standards requiring that every derivative instrument
(including certain derivative instruments imbedded in other contracts) be 
recorded in the balance sheet as either an asset or liability measured at its
fair value.  The Statement requires changes in the derivative's fair value be
recognized currently in earnings unless specific hedge accounting criteria
are met.  SFAS 133 is effective for fiscal years beginning after June 15, 1999.
The Corporation is evaluating the impacts of adopting SFAS 133 on its
financial statements.  The impact of SFAS 133 will likely depend upon the 
extent of use of derivative instruments and their designation and effectiveness
as hedges of market risk.

(6)  Reclassification and Restatements

Certain 1998 amounts have been reclassified to conform to the 1999 
presentation.  Operating results for 1998 have been restated to reflect the
consolidation of Blue Dot. and Expanets effective January 1, 1998.  Such 
reclassifications and restatements had no impact on net income and common
stock equity as previously reported.

(7)  Earnings Per Share

In 1998, the Corporation adopted SFAS No. 128, "Earnings Per Share," which 
establishes two methods for calculating earnings per share, basic and
diluted, and simplifies the previous standards for computing earnings per 
share.  Basic earnings per share is computed on the basis of the weighted
average number of common shares outstanding.  Diluted earnings per share is 
computed on the basis of the weighted average number of common shares
outstanding plus the effect of the outstanding stock options and warrants.
The following table presents the shares used in computing the basic and 
diluted earnings per share for 1999 and 1998 (in thousands):

Item 2. MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION
        AND RESULTS OF OPERATIONS

NorthWestern Corporation ('NorthWestern' or 'Corporation') and its partner
entities are providers of value-added services and solutions to residential
and business customers nationwide.  The Corporation provides electric and 
natural gas service to Midwestern customers through our energy division,
NorthWestern Public Service.  In addition, the Corporation holds interests in 
Cornerstone Propane Partners, L.P. (NYSE:CNO), the nation's fourth largest
retail propane distributor; Expanets, Inc., a national provider of integrated 
communication and data solutions and network services; and Blue Dot Services,
Inc., a national provider of air conditioning, heating, plumbing and related
services (HVAC).  The Corporation is also engaged in other service and 
nonenergy related businesses. NorthWestern was incorporated under the laws of 
the state of Delaware in 1923.  Our executive offices are located at 125 S.
Dakota Avenue, Suite 1100, Sioux Falls, South Dakota 57104, and our telephone
number is 605-978-2908.  Our website is located at www.northwestern.com.
                          
Weather

Weather patterns have a material impact on the Corporation's operating 
performance for all three segments of its energy business.  This impact is
particularly relevant for natural gas and propane. 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
Corporation's market areas.  With a larger proportion of its operations 
related to seasonal propane and natural gas sales, a significantly greater 
portion of the Corporation's operating income is recognized in the first and
fourth quarters related to higher revenues from the heating season.

RESULTS OF OPERATIONS:

Consolidated Earnings Comparisons -

Diluted earnings per share for the quarters ended March 31, 1999 and 1998,
were $.56 and $.58. Excluding a nonrecurring investment gain of $.07 related
to a sale of stock in a nonstrategic investment, March 31, 1998, ongoing 
diluted earnings were $.51 per share.  The increase in ongoing earnings was due
to increased operating income from the propane operations resulting from 
acquired retail propane distribution centers and increased operating income 
from HVAC and communications operations resulting from internal growth and 
acquired companies, offset by decreases due to significantly warmer than normal
weather in the Corporation's propane, natural gas and electric operating areas.

Propane

Retail propane sales for the three months ended March 31 increased 28% from 
$84.5 million in 1998 to $108.2 million in 1999.  Gross margins also 
increased 43% from $44.5 million in 1998 to $63.8 million in 1999.  The
increases are due to internal growth combined with the acquisition of retail
propane centers including a large retail propane distribution company in late
1998.  These increases were negatively impacted by weather that has been 
substantially warmer than normal.  Wholesale propane sales increased 62% from
$144.9 million in 1998 to $232.1 million in 1999. Wholesale propane margins 
also increased 19% from $5.5 million in 1998 to $6.5 million in 1999.  The
increases in wholesale sales and margins are due to acquisitions in late 1998 
offset by warmer than normal weather.  Propane operating income for the
three months ended March 31 increased 42% from $19.8 million in 1998 to $28.1
million in 1999.  The increase in operating income is due to the acquisitions 
of retail and wholesale service centers partially offset by the negative impact
from warmer than normal weather.

Electric

Electric revenues for the three months ended March 31 increased 8% from $19.0
million in 1998 to $20.5 million in 1999.  The increase in revenues is due to
internal growth and increased wholesale sales offset by warmer than normal
weather.  Weather in 1999, while similar to the prior year, was still warmer
than normal negatively impacting electric operations. Operating income from
electric operations increased 13% from $5.7 million in 1998 to $6.4 million in
1999.  The increase in operating income is due to higher revenues and margins 
in 1999 partially offset by normal inflationary increases in operating
expenses and warmer than normal weather.

HVAC

HVAC revenues for the three months ended March 31 increased from $10.6 million 
in 1998 to $52.6 million in 1999.  Margins increased from $4.0 million in 1998
to $20.0 million in 1999. Operating income increased from $.3 million in 1998
to $1.4 million in 1999. The increases are due to internal growth combined
with acquisitions of companies throughout 1998 and continuing into 1999.

Communications

Communications revenues for the three months ended March 31 increased from
$4.2 million in 1998 to $62.8 million in 1999. Margins increased from $1.6 
million in 1998 to $28.3 million in 1999.  Operating income increased from 
$.2 million in 1998 to $6.6 million in 1999.  The increases are due to
internal growth combined with acquisitions of companies throughout
1998 and continuing into 1999.

Natural Gas

Natural gas revenues for the three months ended March 31 increased from $30.0
million in 1998 to $30.1 million in 1999. The increase in revenues is due to
internal growth offset by warmer than normal weather. Weather in 1999, while
similar to the prior year, was still warmer than normal which negatively 
impacted natural gas operations. Operating income from natural gas operations 
increased 10% from $3.5 million in 1998 to $3.9 million in 1999.  The increase 
in operating income is due to higher revenues and margins in 1999 offset by 
normal inflationary increases in operating expenses and warmer than normal 
weather.

Other Income Statement Items

Other operating revenues for 1998 consists principally of manufacturing
revenues (related to the Corporation's former ownership interest in Lucht Inc.
which was sold in 1998) and in 1999 consists of other service businesses.

Other income increased during the three months ended March 31, from $2.7 
million in 1998 to $3.3 million in 1999 principally due to the investment of
additional funds which are a result of the excess proceeds from the debt and 
equity offerings completed by the Corporation in November 1998.  Interest
expense increased from $7.7 million to $11.9 million resulting from debt
issued by the Corporation in November 1998 and Cornerstone in December 1998.
Minority interests increased from $9.1 million in 1998 to $11.2 million in 1999
due to growth within the propane, HVAC and communications businesses. Income 
taxes increased from $4.8 million in 1998 to $7.5 million in 1999 due to 
increased consolidated taxable income.

Liquidity and Capital Resources -

The Corporation believes it has adequate long-term liquidity through the 
generation of operating cash flows, the availability of substantial marketable
securities, and a sound capital structure.  In addition, the Corporation has
adequate capacity for additional financing and continues to maintain this
strong position through favorable bond ratings.

The Corporation 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 three
months ended March 31, 1999 and 1998 were $29.3 million and $21.1 million.
The increase is primarily due to increased cash flow from propane, HVAC and
communication operations. Cash equivalents and investment securities totaled
$170.1 million and $87.5 million at March 31, 1999 and 1998.

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 March 31, 1999, available short 
term lines of credit totaled $75 million.  In addition, the Corporation's
nonregulated subsidiaries maintain nonrecourse credit agreements with various
banks for revolving and term loans.

Capital Requirements -

The Corporation's primary capital requirements include the funding of its
energy business construction, maintenance and expansion programs, the
funding of debt and preferred stock retirements, sinking fund requirements and 
the funding of its corporate development and investment activities.

Maintenance capital expenditure plans are subject to continual review and may 
be revised as a result of changing economic conditions, variations in sales,
environmental requirements, investment opportunities and other ongoing 
considerations. Capital expenditures for maintenance activities during the
three months ended March 31, 1999 and 1998 were $6.5 million and $5.4 million. 
Estimated  annual maintenance capital expenditures for 1999 and 2000 are 
estimated to be $27.3 million and $26.2 million.

Capital requirements for the mandatory retirement of long-term debt including 
nonrecourse debt of subsidiaries will be $8.4 million in 1999.  The Corporation
anticipates that future capital requirements will be met by existing 
investments and marketable securities, internally generated cash flows and 
available external financing.

The Corporation will continue to review economics of retiring or refunding
remaining long-term debt and preferred stock to minimize long-term financing
costs.  At March 31. 1999, the Corporation had invested $215.5 million in Blue 
Dot. and Expanets. The Corporation will continue to make other significant 
acquisition investments in related industries that would require the 
Corporation to raise additional equity and/or incur debt financing,
which are therefore subject to certain risks and uncertainties.  The 
Corporation's financial coverages are at levels in excess of those required for
the issuance of additional debt and preferred stock.

COMPETITION AND BUSINESS RISK

NorthWestern's strategy centers upon the development, acquisition and 
expansions of operations offering integrated services and solutions within the
NorthWestern partner entities.  In addition to maintaining a strong competitive
position in its electric, natural gas and propane distribution businesses, the 
Corporation intends to pursue strategic development and acquisitions that have 
long-term growth potential.  While these strategic development and acquisition 
activities can involve increased risk in comparison to the Corporation's
energy distribution businesses, they offer the potential for enhanced  
investment returns.  The Corporation's strategy to continue strategic
development through acquisitions will be subject to future availability of 
market capital to fund such acquisitions.  The NorthWestern strategy of
integrating products and services and acquired companies have other factors
which may also increase the risks of the Corporation.  These factors include
the adequacy and efficiency of its information systems, business processes,
related support functions and the ability to attract and retain quality team 
members.  The Corporation has taken and continues to take steps to refine, 
improve and scale up its back-office support systems and processes. There are
no assurances that such efforts will be sufficient to meet the future needs of
the Corporation's operations.  Future changes in accounting rules and 
regulations could have a material impact upon the Corporation's future
financial statement presentation, results from operations and financial
position.

PROPANE

The retail propane business is a margin-based business in which gross profits
depend on the excess of sales prices over propane supply costs. Consequently,
CornerStone's profitability will be sensitive to changes in wholesale propane
prices. Propane is a commodity, the market price of which can be subject to 
volatile changes in response to changes in supply or other market conditions.
As it may not be possible to immediately pass on to customers rapid increases
in the wholesale cost of propane, such increases could reduce CornerStone's 
gross profits.

Weather conditions have a significant impact on propane demand for both heating
and agricultural purposes.  The majority of CornerStone's customers rely 
heavily on propane as a heating fuel.  Actual weather conditions can vary 
substantially from year to year, significantly affecting CornerStone's
financial performance.  Furthermore, variations in weather in one or more
regions in which CornerStone operates can significantly affect the total 
volumes sold by CornerStone and the margins realized on such sales and,
consequently, CornerStone's results of operations.  These conditions may also
impact CornerStone's ability to meet various debt covenant requirements and 
affect CornerStone's  ability to pay common and subordinated unit 
distributions.

Propane competes with other sources of energy, some of which are less costly
for equivalent energy value. Propane distributors compete for customers against
suppliers of electricity, fuel oil and natural gas, principally on the basis of
price, service, availability and portability.  Electricity is a competitor of 
propane, but propane generally enjoys a competitive price advantage over 
electricity for space heating, water heating and cooking.  Propane  serves as 
an alternative to natural gas in rural and suburban areas where natural gas is
unavailable or portability of product is required.  Natural gas is generally a 
less expensive source of energy than propane although in areas where natural 
gas is  available, propane is used for certain industrial and commercial
applications.  The gradual expansion of the nation's natural gas distribution
systems has resulted in the availability  of natural gas in some areas that
previously depended upon propane. However, natural gas pipelines are not 
present in many regions of the country where propane is sold for heating and
cooling purposes.

CornerStone's profitability is affected by the competition for customers among 
all participants in the retail propane business. Some of CornerStone's
competitors are larger or have greater financial resources than CornerStone.  
Should a competitor attempt to increase market share by reducing prices,
CornerStone's financial condition and results of operations could be materially
adversely affected. In addition, propane competes with other sources of energy,
some of which may be less costly per equivalent energy value.

ELECTRIC AND NATURAL GAS

The electric and natural gas industries continue to undergo numerous 
transformations, and the Corporation is operating in an increasingly 
competitive marketplace.  The Federal Energy Regulatory Commission (FERC),
which regulates interstate and wholesale electric transmissions, opened up
transmission grids and mandated that utilities must allow others equal access 
to utility  transmission systems.  Various state regulatory bodies are
supporting initiatives to redefine the electric energy market and are 
experimenting with retail wheeling, which gives some retail customers the
ability to choose their supplier of electricity.  Traditionally, utilities have
been vertically integrated, providing bundled energy services to customers. The
potential for continued unbundling of customer service exists, allowing 
customers to buy their own electricity and natural gas on the open market and 
having it delivered by the local utility.

The growing pace of competition in the energy industry has been a primary 
focus of management over the last few years.  The Corporation's future
financial performance will be dependent on the effective execution of
operating strategies to address a more competitive and changing energy 
marketplace. Business strategies focus on enhancing the Corporation's
competitive position, on expanding energy sales and markets with new products
and services for customers, and increasing shareholder value.  The Corporation
has realigned various areas of its business to support customer services and 
marketing functions.  A new marketing plan, an expanded line of integrated
customer products and services, additional staff and new technologies are 
part of the Corporation's strategy for providing responsive and superior 
customer service. To strengthen the Corporation's competitive position, new
technologies have and will be added that enable team members to better serve 
customers. The Corporation is centralizing activities to improve efficiency, 
and customer responsiveness and business processes are being reengineered to
apply best-practices methodologies.  Long-term supply contracts have been
renegotiated to lower customers' energy costs and new alliances help reduce 
expenses and add innovative work approaches.

Weather conditions have a significant impact on electric and natural gas demand
for heating and cooling purposes.  Actual weather conditions can vary
substantially from year to year, significantly affecting the Corporation's 
financial performance.

As described in Note 1 to the 1998 audited annual consolidated financial 
statements, the Corporation complies with the provisions of Statement of
Financial Accounting  Standards No. 71 (SFAS 71), 'Accounting for the Effects
of Certain Types of Regulation'. SFAS 71 provides for the financial
reporting requirements of the Corporation's regulated electric and natural gas 
operations, which requires specific accounting treatment of certain costs and
expenses that are related to the Corporation's regulated operations. 
Criteria that could give rise to the discontinuance of SFAS 71 include 1)
increasing competition that restricts the Corporation's ability to establish
prices to recover specific costs and 2) a significant change in the manner in 
which rates are set by regulators from cost-based regulation to another form
of regulation.  The Corporation periodically reviews these criteria to
ensure the continuing application of SFAS 71 is appropriate.  Based on a
current evaluation of the various factors and conditions that are expected to
impact future cost recovery, the Corporation believes that its regulatory
assets, including those related to generation, are probable of future recovery.
This evaluation of recovery must be updated for any change, which might occur
in the Corporation's c urrent regulatory environment.

HVAC

The markets served by Blue Dot. for residential and commercial heating, 
ventilating, air conditioning, plumbing and other related services are highly
competitive.  The principal competitive factors in these segments of the 
industry are 1) timeliness, reliability and quality of services provided, 2)
range of products and services provided, 3) name recognition and market share 
and 4) pricing.  Many of Blue Dot's competitors in the HVAC business are small
owner-operated companies typically located and operated in a single geographic 
area.  There are a small number of larger national companies engaged in
providing residential and commercial services in the service lines in which
the Corporation intends to focus.  Future competition in both the residential
and commercial service lines may be encountered from other newly formed or
existing public or private service companies with aggressive acquisition
programs, from the unregulated business segments of regulated gas and electric 
utilities, or from newly deregulated utilities in those industries entering
into various service areas.

COMMUNICATIONS

The market served by Expanets in the communications and data services industry
is also highly competitive.  The Corporation believes that 1) market acceptance
of the products, services and technology advances the Corporation provides, 2)
pending and future legislation affecting the communications and data industry,
3) name recognition and market share, 4) larger competitors and 5) the 
Corporation's ability to provide integrated communication and data solutions
for customers in a dynamic industry are all factors that could affect the 
Corporation's future operating results.  Many of Expanet's competitors in the
communications business are generally small, owner-operated companies typically
located and operated in a single geographical area.  There are a number of
large, integrated national companies engaged in providing commercial services
in the service lines in which the Corporation intends to focus and also
manufacture and sell directly the products that the Corporation services and
sells. Future competition may be encountered from other newly formed or
existing public or private service companies with aggressive acquisition 
programs.

YEAR 2000 READINESS

The Corporation utilizes software and various technologies throughout its 
businesses that might be impacted by the date change in the year 2000.  The
year 2000 issue is a result of computer programs which were written using two
digits (rather than the actual four) to identify the year in the date field.
This old approach was intended to saving processing time and storage space
within computers and was continued in use until the mid 1990's.  If not
corrected, affected systems and devices containing computer chips or clocks
could roll back to 1900 instead of moving forward to 2000.  Some systems and
devices may continue to function even if this occurs. Others may experience 
interruptions in service, processes or obtain erroneous results.

In an effort to recognize these critical systems or devices with potential
business consequences, the Corporation is utilizing internal and external
resources to conduct detailed assessments of critical  systems and devices.  
To ensure a thorough approach to the year 2000, the Corporation has assembled a
diverse oversight and advisory team from all businesses with experienced 
information systems, legal, communications and operating leadership to
work on our enterprise-wide year 2000 program. This initiative covers not only 
the Corporation's information technology systems and computer applications, but
also considers hardware, embedded systems and components internal and external
to our organizations.  The Corporation's program considers not only our
businesses and technology areas but also those of our customers and suppliers.

The Corporation's operations are dependent upon complex computer systems for 
many aspects of its businesses.  These different computer information
systems include AS/400, client server and distributed systems.  The 
Corporation's goal is to have mission critical systems or devices that are 
required to maintain operations ready for the year 2000.  Year 2000 ready
means that the system or device has been deemed suitable to operate after
December 31, 1999. Many of the Corporation's mission-critical systems
have been replaced or will be replaced in advance of the year 2000.  
Remediation plans include prioritizing our efforts based on when the systems
might first experience malfunctions as well as possible impact on our 
customers.  The Corporation is on target to remediate all critical applications
early in 1999 and then will devote the remainder of 1999 to work on final
interface issues, remediation, testing and fine-tuning critical items.

The Corporation's costs to prepare for the year 2000  were approximately $2
million during 1998 and an estimated additional $2 million will be incurred
during 1999.  These costs have been expensed as incurred or capitalized in
accordance with our accounting policy for software development costs.

The Corporation's systems and operations with respectto the year 2000 issue
may also be affected by other third parties with which the Corporation 
transacts business.  We rely upon other companies to supply us with products
and services necessary to operate our businesses.  If key third parties cannot 
provide us with products and services as a result of their own year 2000
problem, it could have a material adverse effect upon our operations.  The
extent of such impact would depend upon the duration of such interruption and
our costs and ability to find alternative sources of products and services. The
Corporation is currently working with third parties to determine the potential 
adverse consequences, if any, that could result from such entities' failure
to effectively address the year 2000 issue. The Corporation's primary focus
has been directed at resolving the year 2000 problem.  While the Corporation 
expects that the majority of its systems and devices to be year 2000 ready, the
Corporation is developing a contingency plan specifying what will be done if 
the Corporation or important third parties are not year 2000 ready.  The
Corporation anticipates that the majority of the contingency plan will be
based on manual backup systems, procedures and practices, as well as the 
identification of alternative suppliers for key products or services.
The contingency plan is expected to be completed by June 30, 1999.
