               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               ------------------------------------------
                             (Unaudited)

The Company, in its opinion, has included all adjustments (including normal
recurring accruals) necessary for a fair presentation of the results of
operations for the periods. The financial statements for 1999 are subject to
adjustment at the end of the year when they will be audited by independent
accountants.  The financial statements and notes thereto should be read in
conjunction with the financial statements and notes for the years ended
December 31, 1998, 1997, and 1996 included in the Company's 1998 Annual
Report to the Securities and Exchange Commission on Form 10-K.  Certain
prior year amounts have been reclassified to conform to 1999 presentation.
Because of seasonal and other factors, the earnings for the three-month and
six-month periods ended June 30, 1999, should not be taken as an indication
of earnings for all or any part of the balance of the year.

Common shares and earnings per share
------------------------------------

On February 23, 1999, the Company granted options that would allow the
purchase of 219,000 shares of common stock to eligible employees under the
Company's 1999 Stock Incentive Plan (the "Plan") approved by shareholders on
April 12, 1999.  A total of 1,300,000 shares of the Company's common stock
are available for granting of awards under the Plan. The exercise price of
the stock options is equal to the fair market value per share at the date of
the grant.   The options vest over a four-year period at the rate of 25% per
year and will expire ten years after the date of the grant.  The Company
accounts for the Plan under Accounting Principles Board Opinion No. 25,
which does not require recording of compensation expense. The effects of the
common stock options on the computation of diluted earnings per share were
immaterial for the quarter and six-months ended June 30, 1999.

On April 12, 1999 the shareholders approved the Company's 1999 Employee
Stock Purchase Plan ("Purchase Plan").  The Purchase Plan allows eligible
employees to purchase the Company's common stock at 85% of the lower market
price at either the beginning or the end of each six-month purchase period.
A total of 200,000 shares of the Company's common stock are available for
purchase by employees under the Purchase Plan.

The Company issued 7,102 common shares in the second quarter of 1999 and
44,619 common shares for the six months ended June 30, 1999 under its
Automatic Dividend Reinvestment and Share Purchase Plan. Starting in June
1999, the Company began purchasing the common shares needed for this plan
from the open market instead of issuing new shares.  During 1998, the
Company issued 42,319 and 76,839 common shares for the three and six-month
periods ending June 30, respectively, under the Automatic Dividend
Reinvestment and Share Purchase Plan.

Comprehensive Income
--------------------

Elements of comprehensive income for the three-month period ended June 30,
1999, include net income of $7,146,000 and other comprehensive income of
$222,000 (net of $157,000 in deferred taxes) related to the recognition of
$379,000 in unrealized gains on "available-for-sale" securities held by a
Company subsidiary.  Comprehensive income for the six-month period ended
June 30, 1999, includes net income of $16,395,000 and other comprehensive
income of $313,000 (net of $191,000 in deferred taxes) related to the
recognition of $504,000 in unrealized gains on "available-for-sale"
securities held by a Company subsidiary.

Elements of comprehensive income for the three-month period ended June 30,
1998, include net income of $8,015,000 along with a reduction in accumulated
other comprehensive income of $33,000 (net of $23,000 in deferred taxes)
related to a $56,000 reduction in the market value of securities held as
"available-for-sale".

Comprehensive income for the six-month period ended June 30, 1998, includes
net income of $13,773,000 and other comprehensive income of $116,000 (net of
$81,000 in deferred taxes) related to the recognition of an additional
$197,000 in unrealized gains on "available-for-sale" securities held by a
Company subsidiary.

Rate Matters
------------

As previously disclosed, due to the ongoing review of demand-side management
programs and related incentives by the Minnesota Public Utilities Commission
("MPUC"), the Company has chosen not to record any 1999 conservation program
incentives until approved by the MPUC.  On June 24, 1999, the MPUC approved
the Company's request for recovery of 1998 Conservation Improvement Program
("CIP") financial incentives totaling $1.8 million (which had been accrued for
in 1998) along with a 1.5% CIP surcharge effective July 1, 1999 through
June 30, 2000. The conservation-related costs being recovered through the
surcharge and in base rates include CIP expenditures, carrying costs on CIP
expenditures until they are recovered through rates, lost margins on avoided
kilowatt-hour sales, and bonus incentives related to energy savings.

On May 26, 1999, the Company reached a settlement with the staff of the
North Dakota Public Service Commission  ("NDPSC") following an audit of the
Company's electric operations in North Dakota.  The NDPSC's decision on this
settlement is expected in the third quarter.  The effect of this settlement
on the Company for 1999 is estimated to be $441,000 after taxes or $0.037
per share. In addition, the Company would be allowed to retain all
1999 earnings from North Dakota regulated electric operations up to a 12.5%
return on equity and refund to North Dakota customers any earnings over the
12.5% return.  The Company would also file a proposal for a
performance-based ratemaking plan by year-end.

Segment Information
-------------------

The Company's business operations, which are based mainly in Minnesota,
North Dakota and South Dakota, are broken down into four segments based upon
products and services.  Electric operations include the electric utility
only. Manufacturing operations includes production of agricultural
equipment, plastic pipe, automobile and truck frame-straightening equipment
and accessories, and fabricated metal parts. Health services operations
consists of businesses involved in the sale, service, rental, refurbishing
and operations of medical imaging equipment and the sale of related supplies
and accessories to various medical institutions located primarily in the
Midwestern United States. Other business operations consists of businesses
diversified in such areas as electrical and telephone construction
contracting, entertainment, energy services, natural gas marketing, and
telecommunications.  The Company evaluates the performance of its business
segments and allocates resources to them based on earnings contribution and
return on investment. Substantially all sales and long-lived assets of the
Company are within the United States.

Special charges
---------------

In the first quarter of 1998, the Company recorded special charges that
reflected three items:  (1) a voluntary early retirement offer was accepted
by 55 of the 67 eligible employees resulting in a one-time noncash charge of
$6,305,000 ($3,783,000 net-of-tax or $0.32 per share); (2) an impairment
loss of $2,500,000 ($1,500,000 net-of-tax or $0.13 per share) was recorded
on the write-down of Quadrant's Co. waste incineration plant to an
undepreciated carrying value of $0 under the requirements of SFAS 121; and
(3) as a result of an unfavorable court decision related to the construction
of a rail spur intended to serve Big Stone Plant, the Company wrote off
$717,000 ($430,000 net-of-tax or $0.04 per share) in project related costs.

Cumulative effect of change in accounting principle
---------------------------------------------------

In the first quarter of 1998, the Company changed its method of revenue
recognition from sales of electricity in Minnesota and South Dakota from
meter-reading dates to energy-delivery dates, resulting in the recognition
of $6,364,000 ($3,819,000 net-of-tax or $0.32 per share) in unbilled
revenue.

Forward Looking Information - Safe Harbor Statement Under the Private
Securities Litigation Reform Act of 1995
----------------------------------------

In connection with the "safe harbor" provisions of the Private Securities
Litigation Reform Act of 1995 (the "Act"), the Company has filed cautionary
statements identifying important factors that could cause the Company's
actual results to differ materially from those discussed in forward-looking
statements made by or on behalf of the Company.  When used in this Form 10-Q
and in future filings by the Company with the Securities and Exchange
Commission, in the Company's press releases and in oral statements, words
such as "may", "will", "expect", "anticipate", "continue", "estimate",
"project", "believes" or similar expressions are intended to identify
forward-looking statements within the meaning of the Act.  Factors that
might cause such differences include, but are not limited to, governmental
and regulatory action, the competitive environment, economic factors,
weather conditions, the Company's ability to identify and address all year
2000 issues and other factors discussed under "Factors affecting future
earnings" on pages 22-25 of the Company's 1998 Annual Report to
Shareholders, which is incorporated by reference in the Company's Form 10-K
for the fiscal year ended December 31, 1998.  These factors are in addition
to any other cautionary statements, written or oral, which may be made or
referred to in connection with any such forward-looking statement or
contained in any subsequent filings by the Company with the Securities and
Exchange Commission.

Item 2.  Management's Discussion and Analysis of Condition and
Results of Operations
---------------------

MATERIAL CHANGES IN FINANCIAL POSITION
--------------------------------------

Cash provided by operating activities of $37.2 million as shown on the
Consolidated Statement of Cash Flows for the six months ended June 30, 1999
allowed the Company to pay dividends, finance its capital expenditures and
contribute to the increase in cash and cash equivalents. At June 30, 1999,
the Company and its subsidiaries had $31.2 million available in unused lines
of credit, which could be used to supplement cash needs.  Cash paid for
income taxes as shown on the Consolidated Statement of Cash Flows under
supplemental cash flow information decreased significantly for the six
months ended June 30, 1999, as compared to the same period in 1998, due to a
change in the method of calculating estimated income tax payments.

The Company estimates that funds internally generated, combined with funds
on hand, will be sufficient to meet all sinking fund payments for First
Mortgage Bonds in the next five years and to provide for its estimated
1999-2003 consolidated capital expenditures. During the third quarter of
1999, the Company's $9.00 exchangeable cumulative preferred shares will be
either exchanged for common stock purchased on the open market or redeemed
for cash at a total aggregate cost of $5.3 million using funds on hand.
Additional short-term or long-term financing will be required in the period
1999-2003 in connection with the maturity of First Mortgage Bonds and other
long-term debt and in the event the Company decides to refund or retire
early any of its presently outstanding debt or cumulative preferred shares
or for other corporate purposes.

The $2.5 million decrease in net plant is due to the normal increase in
accumulated depreciation offset by an increase in transmission and
distribution construction projects in the electric utility and expansion of
plant within the manufacturing segment.  Investments increased $4.7 million
as a result of increased investment at the Company's subsidiaries. The
decrease in other accounts receivable of $3.3 million is mainly due to the
timing of payments from the joint owners for the operation of Big Stone
Plant and Coyote Station where the Company serves as operating agent.  The
$4.4 million increase in inventory, materials and operating supplies
reflects increases at the Company's health services and manufacturing
companies due to increased sales and work in progress. The $3.9 million
decrease in accrued utility revenues reflects the reduction in unbilled
revenues due to the seasonal change in weather. Other deferred debits
decreased $1.9 million primarily as a result of timing differences in the
recording of the costs of conservation programs compared to the recovery of
these costs.

The combined increase in common shares, par value and premium on common
shares of $1.7 million is due to the issuance of 44,619 shares of common
stock under the Company's Automatic Dividend Reinvestment and Share Purchase
Plan.  The decrease in other cumulative preferred shares and part of the
increase in sinking fund requirements and current maturities relates to the
exchange or redemption of the Company's $9.00 exchangeable cumulative
preferred shares that will take place during the third quarter. The remaining
increase of $3.9 million in sinking fund requirements and current maturities
reflects a normal seasonal increase in credit line usage at the Company's
manufacturing and construction subsidiaries. The increase in federal and
state income taxes accrued of $4.4 million is related to the timing and
amount of estimated tax payments due to a change in the method of determining
estimated tax payments. The $2.4 million decrease in other taxes accrued is
the result of the timing of property tax payments due in the second quarter,
most of which are paid to the State of Minnesota.

                                            -------    -------  -------

The increase in electric operating revenues for the quarter is due to a $3.2
million (33%) increase in revenues from power pool sales offset by decreases
of  $155,000 (0.4%) in retail revenue and $913,000 (34%) in other electric
revenue. Power pool sales were up significantly due to increased demand in
the pool combined with a high level of availability from the Company's
generating plants. The slight decrease in retail revenue is the result of an
overall 2.1% decrease in retail kwh sales offset by a 1.7% increase in
revenue per kwh sold.  Increases in sales to residential and commercial
customers were offset by decreased sales to industrial customers. Decreases
in electrical contract work done for other utilities combined with the
Company's decision not to record 1999 conservation program incentives until
approved by the MPUC are the primary reasons for the decrease in other
electric revenue.

During the second quarter production fuel expenses increased due to a 4.4%
increase in kwh generated offset by a slight reduction in fuel costs per kwh
generated.  The increase in purchased power expense is commensurate with the
increase in power pool sales.  The decrease in other electric operation and
maintenance expenses is due to a reduction in materials and supplies
expenses partially offset by increased labor expenses.

Four of the Company's seven manufacturing subsidiaries had increased sales
for the quarter.  The reason for the decline in operating income for the
manufacturing segment is primarily due to lower gross margins on new product
lines at one of the manufacturing subsidiaries.

The decrease in operating revenues for the quarter is due to decreases in

decrease in cost of goods sold reflects the decrease in sales volumes.

deductions is due to decreases in demand-side management incentives offset
by increased interest income due to the increase in short-term investments.

                    Interest Charges and Income Taxes
                    ---------------------------------

Interest charges decreased $370,000 (9.0%) during the second quarter due to
the payment of interest during 1998 on the settlement of the 1996 Federal
income tax audit combined with a reduction in outstanding debt and lower
interest rates during 1999. Even though income before income taxes
decreased, income taxes increased $210,000 (5.5%) due to minor adjustments
made for book and tax timing differences.

                                          --------    --------   ------

The increase year-to-date in electric operating revenues is due to a $8.9
million (64%) increase in revenues from power pool sales combined with a
$664,000 (0.7%) increase in retail revenue offset by a $1.3 million (27%)
decrease in other electric revenue. The increase in power pool sales is
related to an increase in energy available for sale, increased demand in the
power pool and increased power marketing sales efforts. The increase in
retail revenue is the result of an increase in cost-of-energy revenues and
an increase in the conservation improvement surcharge revenues offset by a
2.6% decrease in retail kwh sales. The recovery of fuel and purchased power
costs through the cost-of-energy adjustment mechanism in retail rates lags
two to four months behind the incurrance of those costs which gave rise to
the increase in cost-of-energy revenues. Decreases in electrical contract
work done for other utilities combined with the Company's decision not to
record 1999 conservation program incentives until approved by the MPUC are
the primary reasons for the decrease in other electric revenue.

Production fuel expenses for the six months increased as a direct result of
an 8.5% increase in kwh generated offset by a slight decrease in the fuel
costs per kwh generated.   Purchased power expense increased as a result of
a 64% increase in power pool sales, partially offset by a 10% decrease in
kwh purchased for system use. The reduction in purchased power for system
use was due to greater plant availability during the first quarter of 1999
coincidental with a reduction in demand for retail sales.

The decrease in other electric operation and maintenance expenses year-to-
date is primarily related to a reduction in expense due to the early
retirement program in 1998 and a reduction in material and supplies expenses
due to less contracted work for other utilities during 1999.

The special charges recorded under electric operations in the first quarter
of 1998, represent two items: (1) a noncash charge of $6,305,000 associated
with a voluntary early retirement program offered by the Company and, (2)
the write-off of $717,000 in accumulated costs related to a rail spur
project at Big Stone Plant.  (See "Special charges" in notes to consolidated
financial statements on page 8 for further information including the net-of-
tax and earnings per share impact of these charges.)  Excluding the special
charges, this business segment would have shown an increase of $2.5 million
(11.5%) in operating income for the six months ended June 30.

Four of the Company's seven manufacturing subsidiaries had increased sales
year-to-date. The reason for the decline in operating income for the
manufacturing segment is primarily due to lower gross margins on new product
lines at one of the manufacturing subsidiaries.

The increase in operating revenues for the six months reflects overall
increases in sales volumes and an increase in the number of medical imaging
scans performed offset by a decrease in the average fee per scan.  Cost of
goods sold and operating expenses increased as a result of the increased
sale volumes combined with increases in the costs of repair and maintenance
on equipment used to serve customers. These increased operating costs offset
the increase in revenues and resulted in a $536,000 decrease in health
services operating income.

There are two primary reasons for the increases in operating revenues and
cost of goods sold:  (1) larger volume of work contracted at the Company's
construction subsidiaries and (2) the PAM Natural Gas acquisition that
occurred on May 1, 1998. The special charges recorded during the first
quarter of 1998 represent an impairment loss associated with the Quadrant
Co. waste incineration plant. (See "Special charges" in notes to
consolidated financial statements on page 8 for further information
including the net-of-tax and earnings per share impact of these charges.)
Excluding the Quadrant Co. impairment loss, this business segment would have
shown an increase of  $773,000 (259%) in operating income for the six months
ended June 30.

                     Other Income and Deductions - net
                     ---------------------------------

The $295,000 (17%) reduction in other income and deductions year-to-date is
due to decreases in demand-side management incentives offset by increased
interest income and reduced donation expenses.

                     Interest Charges and Income Taxes
                     ---------------------------------

The $700,000 (8.7%) decrease in interest charges is due to a reduction in
outstanding debt and lower average interest rates during 1999 combined with
the payment of interest during 1998 on the settlement of the 1996 Federal
income tax audit. The $5.3 million (134%) increase in income taxes is
primarily due to the increase in income before taxes.

Year 2000 Readiness Disclosure
------------------------------

Many computer software systems, as well as certain hardware and equipment
containing date-sensitive data, were structured to utilize a two-digit year
field meaning that they may not be able to properly recognized dates in the
year 2000. The Company recognizes that the year 2000 occurrence puts all of
its electronic systems on all platforms at risk.  Application systems,
information technology systems and technology that includes embedded systems
are being reviewed, in order, from highly critical to less critical.  These
systems include the Company's financial software, customer-information
system, energy-management system, power plant control systems, manufacturing
processes and diagnostic medical imaging equipment.  In order to address the
year 2000 issue from a total business perspective, the Company is working
with its major vendors, customers, banks, regulatory and government
agencies, and utility alliances.

In order to improve business information systems, the Company's operating
businesses began replacing major financial computer systems in 1996.  The
electric utility has replaced its major in-house developed financial
computer systems with financial applications from Oracle Corporation, while
at the same time, replacing the hardware on which these applications reside.
Because of the recent implementation, these systems should require minimal
remediation efforts. The costs of replacing these major financial computer
systems are not included in the cost estimates discussed below.

The Company's plan to resolve the year 2000 issues involves three phases:
inventory, assessment and remediation/testing. The inventory phase was
completed in December 1998 for the electric utility and as of June 30, 1999
is 99% complete for the other companies.  The assessment phase was completed
in February 1999 for the electric utility and is 98% complete for the other
companies as of June 30, 1999.  The remediation and testing phase was
completed in June 1999 for the electric utility and is 85% complete for the
other companies as of June 30, 1999. The other companies are on schedule to
complete the inventory, assessment and remediation/ testing phases by
October 31, 1999.  The electric utility will continue to refine its
contingency plans for January 1, 2000.

In addition, the Company's operating businesses are communicating with
critical external parties in order to determine the extent of vulnerability
to such parties' failure to resolve their own year 2000 issues. The
subsidiary companies have completed 85% of their third party assessments and
expect to have the remaining work completed by September 30, 1999. The
Company is developing plans to alter business relationships in the event
certain third parties fail to become year 2000 compliant.  There can be no
guarantee that the third parties of business importance to the Company will
successfully reprogram or replace and test all of their own computer
hardware, software, and process control systems in a timely manner.  While
the failure of a single third party to achieve year 2000 readiness should not
have a material adverse effect on the Company's financial results or
operations, the failure of several key third parties could have such an
effect.

The electric utility industry is unique in its dependence upon a complex
network of interrelated systems of the power pool grid in order to support
and maintain reliable, efficient operations.  The Company's year 2000
readiness effort is linked to the readiness efforts of other utilities, as
well as those of major customers whose loads support the integrity of the
power pool grid.  The Company is coordinating its year 2000 effort with that
of the Mid-Continent Area Power Pool and with plans established by the North
America Electric Reliability Council ("NERC") under the direction of the
U. S. Department of Energy.  The Company successfully participated in the
April 9, 1999 NERC drill to simulate loss of multiple voice and data
communications systems.  The Company also plans to participate in the
September 1999 NERC drill.  The goal of this drill is to simulate as
realistically as is practical the implementation of administrative,
operating, communications and contingency response plans for the year 2000
transition.  While the Company is supporting these cooperative efforts, it
cannot guarantee the successful implementation of solutions of third
parties.  A failure of a system within the power pool grid could have a
material impact on the Company and its customers.

The costs of the Company's year 2000 readiness effort are being funded with
cash flows from operations. These costs are not expected to be substantially
different from the normal, ongoing costs that are incurred for systems
development, implementation and maintenance due in part to the use of
internal resources and the deferral of other projects. Total expenditures
related to the Company's year 2000 readiness effort is expected to range
from $975,000 to $1,350,000 for 1997 to 2000. Expenditures incurred through
June 30, 1999, most of which have occurred at the electric utility, are
estimated at $625,000.  The Company does not track year 2000 costs in a
separate account.

The Company's medical subsidiary owns diagnostic imaging equipment which has
computer software that is vulnerable to year 2000 issues.  While the medical
subsidiary will negotiate to have its vendors pay the costs to solve the
year 2000 issues, there can be no assurances the vendors will absorb the
costs. In the event the vendors do not pay all or some portion of the costs,
the medical subsidiary would have to absorb the majority of the costs.
These costs are included in the estimates shown above.

As part of its normal business practice, the electric utility maintains
emergency backup and recovery procedures to be followed in the event of
failure of a business-critical system. These procedures were expanded to
include specific procedures for potential year 2000 issues.  The business
critical processes contingency plans were approved in April of 1999.  The
Company's electrical system contingency plan, which was completed and
approved in June 1999, used templates provided by the NERC.  This plan
includes meeting with large customers to determine their operating plans
during critical dates.  The Company also has plans to provide for additional
staffing at critical locations to respond to any year 2000 situations that
might arise.  Contact is ongoing with neighboring utilities to coordinate
contingency plans, operating plans, and the year 2000 backup communications
drill.

At this time, the Company believes its worst case scenario is that key
customers could experience significant reductions in their power needs due
to their own year 2000 issues.  Although the Company does not believe that
this scenario is likely to occur, the Company expects that such a scenario
would not have a material adverse affect on the Company's consolidated
financial position. The Company believes a more probable worst case scenario
is a temporary disruption of service to its electric customers, including
the effect of cascading disruptions caused by other entities whose
electrical systems are connected to the Company's.  The Company has assessed
the risk of this scenario, and believes that contingency plans would mitigate
the long-term effect of such a scenario.  In the event that a temporary
disruption in service does occur, the Company does not expect that it would
have a material adverse effect on its consolidated financial position.

While the Company believes it will be able to resolve its year 2000 issues
in a timely manner, if it is unable to complete the required changes to
existing critical systems, or if those with whom the Company conducts
business are unsuccessful in implementing timely solutions, the year 2000
issue could have a material adverse effect upon the Company's consolidated
results of operations.

The costs of the project and the completion dates are based on management's
best estimates, which were derived from assumptions of future events
including the availability of resources, third party modification plans, and
other factors.  There can be no guarantee that these estimates will be
achieved and actual results could vary due to uncertainties.

Item 2.    Changes in Securities
           ---------------------

     During May 1999, the Company sold 6,490 shares of common stock,
     acquired in the open market, as part of the final payment in
     connection with the acquisition of PAM Natural Gas, Inc. to some of
     the former owners.  The sale of such shares did not involve a public
     offering and therefore was exempt from registration pursuant to
     section 4(2) of the Securities Act of 1933, as amended.

Item 3.    Legal Proceedings
           -----------------

     During June 1999, Quadrant and the Company reached a settlement with
     the Minnesota Pollution Control Agency (MPCA) regarding the 1998
     claimed violations of emission limits, operational requirements and
     reporting requirements applicable to Quadrant under Minnesota law.
     Under the settlement, Quadrant admitted no wrongdoing and agreed to
     pay $80,000 in fines to the MPCA and $70,000 to the City of Perham,
     Minnesota.  These payments were fully covered by reserves previously
     established by Quadrant. In addition, Quadrant agreed to transfer all
     of its assets to the City of Perham and agreed not to operate or
     manage a waste incinerator facility in the future.

Item 4.    Submission of Matters to a Vote of Security Holders
           ---------------------------------------------------

     The annual meeting of Shareholders of the Company was held on April 12,
     1999, for the purpose of electing three nominees to the Board of
     Directors with terms expiring in 2002, approving the appointment of
     auditors, voting on an Amendment to the Articles of Incorporation to
     increase the authorized number of Common Shares to 50,000,000 shares,
     and voting on proposals to approve two new stock-based benefit plans,
     the 1999 Employee Stock Purchase Plan and the 1999 Stock Incentive
     Plan.  Proxies for the meeting were solicited pursuant to Section
     14(a) of the Securities Exchange Act of 1934, as amended, and there
     was no solicitation in opposition to management's solicitations.  All
     nominees for directors as listed in the proxy statement were elected.
