                             BLACK HILLS CORPORATION

                   Notes to Consolidated Financial Statements
        (Reference is made to Notes to Consolidated Financial Statements
                   included in the Company's Annual Report and Form 10-K)


(1)  Management's Statement

     The financial  statements included herein have been prepared by Black Hills
Corporation (the Company)  without audit,  pursuant to the rules and regulations
of the  Securities and Exchange  Commission.  Certain  information  and footnote
disclosures  normally  included in financial  statements  prepared in accordance
with generally  accepted  accounting  principles  have been condensed or omitted
pursuant to such rules and regulations;  however,  the Company believes that the
footnotes  adequately  disclose  the  information  presented.   These  financial
statements  should be read in conjunction with the financial  statements and the
notes  thereto,  included in the Company's 1998 Annual Report on Form 10-K filed
with the Securities and Exchange Commission.

     Accounting  methods  historically  employed require certain estimates as of
interim  dates.  The  information   furnished  in  the  accompanying   financial
statements  reflects all  adjustments  which are, in the opinion of  management,
necessary for a fair  presentation of the March 31, 1999,  December 31, 1998 and
March 31, 1998, financial  information and are of a normal recurring nature. The
results of operations  for the three and twelve months ended March 31, 1999, are
not necessarily indicative of the results to be expected for the full year.


(2)   Capital Stock

      In April 1999, the Board of Directors  authorized the acquisition of up to
1,000,000  shares  of the  Company's  Common  Stock on the open  market  to fund
possible future acquisitions by the Company, for its Employee Stock Option Plan,
and for other general  purposes.  The Board had authorized a similar purchase of
300,000  shares in April 1998.  At March 31,  1999,  the  Company  has  acquired
275,701  shares for such  purposes  and is  reflected  as treasury  stock on the
accompanying consolidated balance sheets.




(3)   Net Income Per Share

      Financial  Accounting  Standards Board (FASB)  Statement No. 128 "Earnings
Per Share" requires the  presentation  of basic and diluted  earnings per share.
Basic earnings per share is computed by dividing net income  available to common
shareholders by the weighted average number of common shares  outstanding during
each year.  Diluted  earnings  per share is computed  under the  treasury  stock
method and is calculated  to compute the dilutive  effect of  outstanding  stock
options.  A reconciliation of these amounts is as follows (in thousands,  except
per share amounts):

(4)   Comprehensive Income

      FASB  Statement No. 130,  "Reporting  Comprehensive  Income,"  establishes
standards for reporting and display of comprehensive earnings and its components
in financial  statements.  Statement No. 130 requires minimum pension  liability
adjustments,  unrealized  gains or  losses on the  Company's  available-for-sale
securities and foreign currency translation adjustments, which prior to adoption
were  reported  separately  in  shareholders'  equity,  to be  included in other
comprehensive earnings.  There were no material differences between net earnings
and  comprehensive  earnings  for  any  periods  presented  in the  accompanying
financial statements.

(6)   Energy Trading and Risk Management Activities

      Effective  January 1, 1999, the Company adopted the provisions in Emerging
      Issues Task Force  98-10,  "Accounting  for  Contracts  Involved in Energy
      Trading and Risk  Management  Activities.  (EITF  98-10)."  EITF  requires
      disclosure  of energy  trading  and risk  management  activity  for energy
      contracts  used for trading  purposes.  At March 31, 1999, the Company had
      approximately  220,000  mmbtus of  natural  gas  forward  sales at a fixed
      price. The market value of such contracts approximated the fixed price.





                Management's Discussion and Analysis of Financial Condition
                            and Results of Operations


Liquidity, Capital Resources, and Commitments

     In the past the Company  has  depended  upon  internally  generated  funds,
issuance of short and  long-term  debt and sales of common  stock to finance its
activities.  It is expected that future  activities will also be financed by the
most appropriate mix of these various sources of funds.

     The Company currently has bank lines of credit totaling $44,000,000,  which
provide for  interim  borrowings  and the  opportunity  for timing of  permanent
financing. The Company had $3,330,000 outstanding under these lines of credit on
March 31, 1999. There are no compensating balance  requirements  associated with
these lines of credit.

      In addition to the above lines of credit,  Black Hills  Energy  Resources,
Inc. has an  uncommitted  demand  credit  facility  for up to $65 million.  This
facility allows $50 million for a  transactional  line of credit and $15 million
overdraft  line of credit.  This  facility  is used to support  the  issuance of
letters  of  credit.  At March  31,  1999,  Black  Hills  Energy  Resources  has
approximately $21 million of outstanding letters of credit.

      In  addition to the above lines of credit,  Wyodak  Resources  Development
Corp. has guaranteed a $15,000,000  line of credit for Enserco  Energy,  Inc. to
use to guarantee  letters of credit.  At March 31, 1999,  there were no balances
outstanding on this line of credit.

Market Risk Disclosures

      There has not been any  significant  changes in market risk since December
31, 1998.

   Commodity Risk

      The Company is exposed to market risk  stemming  from changes in commodity
prices.  These changes could cause  fluctuations  in the Company's  earnings and
cash flows.

   Trading Activities

      For trading  transactions  that do not qualify for hedge  accounting,  the
Company utilizes marked-to-market accounting, and such financial instruments are
recorded at fair value with realized and unrealized gains (losses) recorded as a
component of income.  The quantities  and maximum terms of derivative  financial
instruments  held  for  trading  purposes  at  March  31,  1999 and 1998 are not
significant to the Company's financial position or results of operations.





   Non-trading Activities

      The  notional  quantities  and  maximum  terms  of  derivative   financial
instruments  held for  non-trading  activities at March 31, 1999,  are presented
below:

                                   Volume Purchased  Max. Term   Fair Value
                                       (MMBtu's)      (Years)   (in thousands)
                                   ---------------   ---------   ------------
Natural gas futures contracts 
purchased                               860,000          2           $(61)
Natural gas swap contracts           
purchased                            18,852,042          3        $(1,566)
Natural gas swap contracts sold      15,877,420          1           $738

      Because these contracts are entered into for hedging purposes, the Company
expects  that  the  gains  (losses)  will be  offset  by gains  (losses)  on the
underlying  physical  transactions;  Such physical  transactions  are subject to
weather  trends,  transportation  and delivery  risks and other factors that the
Company  monitors on a regular basis.  The notional  amounts  detailed above are
intended  to  be  indicative  of  the  Company's   level  of  activity  in  such
derivatives.

      At March 31, 1999, the Company did not have material crude oil derivatives
in its non-trading activities.


Interest Rate Risk

      The  Company's  exposure  to market  risk for  changes in  interest  rates
relates  primarily to the Company's  short-term  investments  and long-term debt
obligations.  The Company does not use derivative  financial  instruments in its
available for sale securities.

      At March 31,  1999,  the effect of a 100 basis point  increase in interest
rates does not have a material effect to the Company's  results of operations or
financial condition, due to the short-term duration of the investment portfolio.

      The Company has no cash flow  exposure due to rate  changes for  long-term
debt obligations.  The Company primarily enters into debt obligations to support
general corporate  purposes  including capital  expenditures and working capital
needs.


Results of Operations

      Black Hills Corporation is an energy company  consisting of five principal
businesses: electric, coal mining, oil and gas production, crude oil and natural
gas marketing, and communications.






      Consolidated  net income was  $9,035,000  for the three  months  ended and
$35,104,000 for the twelve months (before a special non-cash charge) ended March
31, 1999, representing an increase of 6 percent and 9 percent,  respectively. In
December 1998, the Company  recorded an $8.8 million after tax charge  primarily
due to a non-cash write down of certain oil and natural gas assets. Consolidated
revenues and fuel and purchased power expense increased for the three and twelve
months ended March 31, 1999  primarily  due to oil and natural gas purchases and
sales from the energy marketing operations.

      Consolidated revenue and income from continuing operations provided by the
Company's businesses as a percentage of the total were as follows:

Electric Operations

      Electric  revenues  increased  3 percent  for the three and  twelve  month
periods ending March 31, 1999, despite milder weather. Degree days, a measure of
weather  trends,  were 11 percent  and 5 percent  lower for the three and twelve
month  periods  as  compared  to the prior  periods.  Total  kilowatthour  sales
increased 6 percent and 12 percent for the three and twelve  month period due to
increased  residential,  commercial  and  non-firm  sales  partially  offset  by
decreased  industrial sales. In addition,  our low-cost  generation  allowed the
Company to  recapture a portion of the decline in  industrial  sales in the spot
energy market.

      Electric  expenses were stable for the three and twelve months ended March
31, 1999 due to continued cost  containment  and lower  purchased power and fuel
costs offset by increased taxes other than income.


Mining Operations

      Mining  earnings  were stable and  increased 6% the three and twelve month
periods ending March 31, 1999.  Earnings increased $513,000 for the twelve month
period in part due to increased  revenue,  lower  operating  costs and increased
interest  income.  Tons of coal sold  increased  slightly  compared to the prior
year.


Oil and Gas Production Operations

      Earnings  from oil and gas  operations  increased  $81,000  for the  three
months and decreased $691,000 (excluding a write-down of certain assets) for the
twelve months ended March 31, 1999, as compared to 1998. Increased earnings were
primarily due to increased oil and natural gas  production  and lower  depletion
expense  partially  offset by lower commodity prices for the three month period.
Production  increased  23 percent and 20 percent for the three and twelve  month
periods.  Oil and  natural  gas  prices  decreased  26 percent  and 17  percent,
respectively,  for the three  months  ended March 31, 1999 and 33 percent and 15
percent, respectively for the twelve month period.

      In December 1998,  Black Hills  Exploration  and  Production  recognized a
$13,546,000  pretax loss related to a write down of oil and gas properties.  The
write down was primarily due to historically low crude oil prices, lower natural
gas prices and decline in value of certain unevaluated properties.  Absent other
factors  impacting  depletion  expense,  the Company  expects  future  depletion
expense per unit of production to be reduced because of this write down.


Energy Marketing Operations

      Energy marketing  revenue  increased in the three months and twelve months
ended March 31, 1999 due to  increased  natural  gas,  crude oil and coal sales.
Although energy  marketing  earnings were negative in the three and twelve month
periods,  the negative earnings  improved $304,000 and $1,428,000,  respectively
for the three and twelve months ended March 31, 1999. The increase was primarily
due to  increased  volumes and margins in the  natural  gas,  crude oil and coal
marketing  areas in  targeted  markets  in the first  quarter of 1999 and fourth
quarter of 1998.



      Crude oil and natural gas wholesale marketing  operations are high-volume,
low margin operations. The operations marketed 518,700 mmbtus and 20,000 barrels
of oil per day in the three month period ended March 31, 1999 and 306,700 mmbtus
and 14,900  barrels of oil per day for the three  month  period  ended March 31,
1998.  For the twelve month period  ending  March 31, 1999,  507,400  mmbtus and
20,300  barrels of oil per day were  marketed as compared to 258,900  mmbtus and
13,400  barrels of oil per day were marketed  since the Company  acquired  Black
Hills Energy Resources in July 1997.


Communications Operations

      Build out of the Black  Hills  FiberCom  network  continues  and the first
customers  are expected to be served later this summer.  Start up losses did not
significantly impact earnings and were in line with management's expectations.


Year 2000 Issues

      What is referred to as the Year 2000 problem  ("Year 2000 problem") is the
result of computer  programs  being written using two digits rather than four to
define the applicable  year. Any of the Company's  computer systems and products
that have  date-sensitive  software may  recognize a date using "00" as the Year
1900  rather  than the Year  2000.  This  could  result in a system  failure  or
miscalculations  causing  disruptions  of  operations,  including,  among  other
things, a temporary inability to process transactions,  send invoices, or engage
in  similar  normal  business  activities.  Management  has  formed a Year  2000
Committee to establish and ensure the Company's compliance with what is commonly
known as the "Year 2000  problem".  In addition,  consultants  may be engaged to
assist with a  comprehensive  review of the Company's  state of readiness and to
assist with any  necessary  remedial  plans for the Year 2000 date  change.  The
Company's review encompassed supporting information technology systems,  product
generation  and  distribution  systems,  and business  supply chain  systems and
infrastructure.  Management  presently  believes that with  modifications to the
Company's  existing  software and  conversions  to new  software,  the Year 2000
problem can be mitigated. However, if such modifications and conversions are not
made, or are not completed on a timely basis, the Year 2000 problem could have a
material  adverse  effect on the  Company's  business,  financial  condition and
results  of  operations.  Management  further  believes  that the cost of either
repairing or replacing  certain business systems to ensure business  continuance
beyond  Year  2000  should  not have a  significant  impact  on the  results  of
operations.  The cost of the Year 2000  project is  currently  estimated at less
than $1 million and is being funded through  operating  cash flows.  These costs
are primarily  attributable  to the purchase of new software and equipment which
will be  expensed  or  capitalized  on a basis  consistent  with  the  Company's
accounting policies for capital assets.  Other than seeking  representations and
assurances,  the  Company  has not made an  assessment  as to whether any of its
customers,  suppliers or service  providers will be affected by the date change.
The Company's  business,  financial  condition and results of operations  may be
adversely  impacted  should  the  efforts  of  customers,  suppliers  or service
providers for the Company to address the Year 2000 issue prove to be inadequate.
The Company's risk management  program  includes  emergency  backup and recovery
procedures to be followed in the event of failure of a business-critical system.
These procedures will be expanded to include  specific  procedures for potential
Year  2000  issues.   Contingency  plans  to  protect  the  business  from  Year
2000-related  interruptions are being developed. These plans will be complete by
June 1999 and will  include,  for  example,  development  of backup  procedures,
identification of alternate suppliers and possible increases in safety inventory
levels.


Forward Looking Statements

      The above information includes forward-looking statements that are subject
to certain risks,  uncertainties and assumptions.  Although  management believes
that its  expectations  are  based  on  reasonable  assumptions,  it can give no
assurances that its goals will be achieved. Actual results may differ materially
from  management's  expectations as a result of a variety of factors  including,
but not  necessarily  limited  to,  technological  changes,  regulation,  market
conditions and marketing success,  general economic  conditions,  and a changing
competitive environment.
