PART I

ITEMS 1 AND 2.  BUSINESS AND PROPERTIES

General

We  are  a  growth  oriented,   diversified  energy  holding  company  operating
principally in the United States. Our regulated and unregulated  businesses have
expanded  significantly in recent years.  Our independent  energy group produces
and  markets  power and fuel.  We produce  and sell  electricity  in a number of
markets,  with a strong  emphasis on the western United States.  We also produce
coal,  natural  gas and crude oil  primarily  in the Rocky  Mountain  region and
market  fuel  products  nationwide.  We also own Black  Hills  Power,  Inc.,  an
electric utility serving approximately 58,600 customers in South Dakota, Wyoming
and  Montana.  Our  communications  group  offers   state-of-the-art   broadband
communication  services to residential and business  customers in Rapid City and
the northern  Black Hills region of South Dakota.  Our  predecessor  company was
incorporated  and began  providing  electric  utility  service in 1941 and began
selling and marketing various forms of energy on an unregulated basis in 1956.

As the following table illustrates,  we have experienced significant growth over
the last five years,  primarily as a result of the expansion of our  independent
energy business and increases in wholesale electric sales.

Holding Company Formation

At our  annual  meeting  of  shareholders  on June 20,  2000,  our  shareholders
approved  the  formation  of a  holding  company  structure  through  a "plan of
exchange" between Black Hills  Corporation and Black Hills Holding  Corporation.
The plan of exchange provided that each share of Black Hills Corporation  common
stock would be exchanged for one share of common stock of the holding company.

On December  22,  2000,  articles of exchange  were filed with the South  Dakota
Secretary of State. As a result:

o    all common  shareholders of Black Hills Corporation became  shareholders of
     Black Hills Holding Corporation, the holding company;

o    Black Hills  Corporation  became a  wholly-owned  subsidiary of Black Hills
     Holding Corporation;

o    Black Hills Corporation  changed its name to "Black Hills Power,  Inc." and
     the holding company changed its name to "Black Hills Corporation"; and

o    the debt securities and other  financial  obligations of Black Hills Power,
     Inc. continue to be the obligations of Black Hills Power, Inc.

The  formation of our holding  company  structure  allows us to pursue,  through
separate subsidiaries,  business opportunities in both regulated and unregulated
markets.

Industry Overview

In the last decade,  many U.S.  regulatory  bodies have taken steps to transform
the energy  sectors  which they  regulate to  encourage  competition,  introduce
customer choice and, in some cases,  to improve the  operational  performance of
strategic  energy  assets.  In  particular,   the  electric  power  industry  is
undergoing  substantial  change as a result  of  regulatory  initiatives  at the
federal and state levels. As early as the mid-1990's, new regulatory initiatives
to increase  competition  in the  domestic  power  generation  industry had been
adopted or were being  considered at the federal  level and by many states.  The
primary  focus  of  such  efforts  was  to  increase   competition  through  the
disaggregation of the traditional utility functions of generation, transmission,
distribution   and  marketing  of  electricity  into  competitive  or  partially
regulated  businesses.  This resulted in new investment  opportunities  to enter
previously non-competitive or closed markets.

In 1992,  the Federal  Energy  Regulatory  Commission  (FERC)  issued Order 636,
followed by Order 888 in 1996,  to  increase  competition  by easing  entry into
natural gas and electricity  markets.  These orders require owners and operators
of  natural  gas and power  transmission  systems to make  transmission  service
available on a non-discriminatory  basis to energy suppliers. In order to better
assure  competitive access to the transmission  network on a  non-discriminatory
basis,  FERC  issued  Order 2000 in December  1999,  which  encourages  electric
utilities  with  power   transmission   assets  to  voluntarily   form  regional
transmission  organizations  to  provide  regional  management  and  control  of
transmission assets independent of firms that sell electricity.



The electric  power  industry has also  witnessed  growing  consumer  demand and
increasingly  frequent  regional  shortages of  electricity  over the past three
years.  The summers of 1998,  1999 and 2000 and the winter of 2000-2001 have all
been  characterized  by very high peak  prices  for  electricity  in a number of
recently  created  wholesale  electricity  markets.  We believe that substantial
amounts  of new  electric  generating  capacity  need  to be  built  to  relieve
shortages of electricity and to replace inefficient and obsolete facilities.

The oil and gas industry has experienced  strong  increases in commodity  prices
since the  historically  low levels  experienced in 1998.  These price increases
have been driven in part by several years of modest drilling  activity  combined
with strong  growth in demand for energy  commodities.  Continued  growth of the
Internet and other high  technology  industries  is  contributing  to increasing
demand for power.  Demand for natural  gas is  expected  to remain  strong as an
increasing number of gas-fired power plants are brought into service.

The  telecommunications  industry is  currently  undergoing  widespread  changes
brought about by, among other things,  the  Telecommunications  Act of 1996, the
decisions of federal and state  regulators to open the monopoly local  telephone
and cable  television  markets to  competition  and the need for  higher  speed,
higher  capacity  networks to meet the increasing  consumer  demand for expanded
telecommunications services, including broader video choices and high speed data
and  Internet  services.  The  convergence  of  these  trends  and the  inherent
limitations of most existing  networks have created  opportunities for new types
of communications  companies  capable of providing a wide range of voice,  video
and  data  services   through  new  and  advanced  high  speed,   high  capacity
telecommunications networks.

As a  result  of  historical  and  anticipated  regulatory  initiatives  and the
increasing demand for electricity, fuel and broadband services, we believe there
are significant  opportunities for the development and growth of our independent
energy businesses, our regulated utility and our communications business.

Strategy

Our  strategy  is  to  build  long-term   shareholder  value  by  deploying  our
development,  operating and marketing expertise in the energy industry.  We plan
to  operate  a mix of  unregulated  independent  energy  and  regulated  utility
businesses,   with  emphasis  on  the  independent  power  generation  and  fuel
production  segments.  We expect our  independent  energy  businesses to operate
nationwide,  with an  integrated  regional  emphasis on the western  half of the
United  States.  Our utility and  communications  businesses  intend to continue
focusing their retail operations primarily on the northern Black Hills region of
South Dakota,  with wholesale  power sales  concentrated  primarily in the Rocky
Mountain and West Coast regions.

Our strategy includes the following key elements:

o    grow our independent  power unit by developing and acquiring power projects
     primarily in the western United States;

o    expand the  generating  capacity of our existing  sites  through a strategy
     known as "brownfield development;"

o    sell a large  percentage  of the  production  from  our  independent  power
     projects  through  long-term   contracts  in  order  to  secure  attractive
     investment returns;

o    increase  our  reserves  of  natural  gas and crude oil and expand our coal
     production;

o    exploit our fuel cost advantages and our operating and marketing  expertise
     to remain a low-cost power producer;

o    exploit  our  knowledge  and  market  expertise  while  managing  the risks
     inherent in fuel marketing;



o    build and maintain strong  relationships  with wholesale energy  customers;
     and

o    capitalize on our utility's established market presence,  relationships and
     customer loyalty.

Grow our  Independent  Power Unit by  Developing  and Acquiring  Power  Projects
Primarily in the Western United States.  Our aim is to continue the  development
of power  plants in  regional  markets  based on  prevailing  supply  and demand
fundamentals in a manner that  complements our existing fuel assets and fuel and
energy marketing capabilities. This approach aims to capitalize on market growth
while managing our fuel procurement needs. Over the next few years, we intend to
grow through a combination of disciplined  acquisitions  and  development of new
power  generation  facilities  primarily in the Rocky  Mountain  region where we
believe we have the detailed  knowledge of market  fundamentals  and competitive
advantage to achieve  attractive  returns.  We believe the following trends will
provide us with growth opportunities in the future:

o    Demand for  electricity  in the Rocky  Mountain and West Coast regions will
     continue to grow and new generation capacity will be required over the next
     several years.

o    New electric generation construction will be predominantly gas-fired, which
     may  create  further  competitive  cost  advantages  for new  and  existing
     coal-fired generation assets.

o    Transmission   construction   will   significantly   lag   new   generation
     development,   favoring  new  development  located  near  load  centers  or
     existing, unconstrained transmission locations.

o    Disaggregation   of  the  electric  utility  industry  from   traditionally
     vertically  integrated  utilities into separate  generation,  transmission,
     distribution  and  marketing  entities  will  continue,   thereby  creating
     opportunities for acquisitions and joint ventures.

Expand the Generating Capacity of Our Existing Sites Through a Strategy Known as
"Brownfield  Development." We believe that existing sites with opportunities for
brownfield  expansion  generally  offer the potential  for greater  returns than
development  of new sites  through a  "greenfield"  strategy.  Brownfield  sites
typically offer several  competitive  advantages  over  greenfield  development,
including:

o    proximity to existing transmission systems;

o    operating cost advantages related to ownership of shared facilities;

o    a less costly and time consuming permitting process; and

o    potential ability to share  infrastructure  with existing facilities at the
     same site.

We are currently expanding our capacity with brownfield  development underway at
our Arapahoe,  Valmont and Wygen sites, and believe that our Fountain Valley and
Wygen  sites in  particular  provide  further  opportunities  for a  significant
expansion of our gas- and coal-fired  generating  capacity over the next several
years.

Sell a Large  Percentage of the Production From Our  Independent  Power Projects
Through Long-Term  Contracts in Order to Secure Attractive  Investment  Returns.
Recent extreme price volatility in the short-term power markets are resulting in
greater  demand  among our  wholesale  customers  for mid- and  long-term  power
purchase  agreements.  By selling the majority of our energy and capacity  under
mid- and long-term contracts, we believe that we can satisfy the requirements of
our customers  while earning more stable  revenues and greater  returns over the
long  term than we could by  selling  our  energy  into the more  volatile  spot
markets.  In recent months, for example,  we have entered into long-term tolling
agreements  covering  nearly  all of  the  gas-fired  energy  and  capacity  our
independent  power unit is adding through  brownfield  expansion of the Arapahoe
and Valmont  sites and from the  Fountain  Valley  project.  See  "--Independent
Energy -- Independent Power Plants."



Increase Our Reserves of Natural Gas and Expand Our Coal  Production.  We aim to
support the fuel  requirements of our growing  portfolio of power plants as well
as power plants owned by others by emphasizing  natural gas and coal production.
Our  strategy is to expand our natural gas  reserves  through a  combination  of
acquisitions  and drilling  programs and expand our coal production  through the
construction  of  mine-mouth  coal-fired  generation  plants at our Wyodak  mine
location.  Our objective is to maintain  coal  reserves to serve our  mine-mouth
coal-fired  generation plants directly,  and to maintain  sufficient natural gas
production  either to directly serve or indirectly  hedge the fuel cost exposure
of our gas-fired generation plants. Specifically, we plan to:

o    substantially  increase our natural gas  reserves and minimize  exploration
     risk by focusing on lower-risk exploration and development drilling as well
     as acquisitions of proven producing properties;

o    exploit  our belief that the  long-term  demand for natural gas will remain
     strong by emphasizing  natural gas, rather than oil, in our acquisition and
     drilling activities;

o    add natural gas  reserves and  increase  production  by focusing on various
     shallow gas plays in the Rocky Mountain region,  where the added production
     can  be  integrated  with  our  fuel  marketing   and/or  power  generation
     activities;

o    increase  coal  production  and sales from our Wyodak mine by continuing to
     develop additional  mine-mouth generating facilities at the site, including
     the Wygen I plant, which is scheduled for completion in spring 2003; and

o    pursue future sales of coal from the Wyodak mine to  rail-served  customers
     by reducing the moisture content of our coal so that we can ship it greater
     distances.

Exploit Our Fuel Cost  Advantage and Our  Operating  and Marketing  Expertise to
Remain a Low-Cost  Power  Producer.  We expect to expand our  portfolio of power
plants  having  relatively  low marginal  costs of producing  energy and related
products  and  services.  We  intend  to  utilize a  low-cost  power  production
strategy,  together with access to coal and natural gas reserves, to protect our
revenue  stream as an  increasing  number of gas-fired  power plants are brought
into  operation.  Low  marginal  production  costs can result  from a variety of
factors,  including low fuel costs,  efficiency in converting  fuel into energy,
and low per unit operation and maintenance  costs. We have aggressively  managed
each of these factors to achieve very low  production  costs,  especially at our
coal-fired and hydroelectric generating facilities.

Our primary  competitive  advantage is our coal mine,  which is located in close
proximity to our retail service  territory.  We are  exploiting the  competitive
advantage  of  this  native  fuel  source  by  building  additional   mine-mouth
coal-fired  generating  capacity.  This  strengthens  our position as a low-cost
producer since transportation costs often represent the largest component of the
delivered cost of coal.

Exploit Our Knowledge and Market  Expertise While Managing the Risks Inherent in
Fuel  Marketing.  We aim to apply our  knowledge of and expertise in the natural
gas  transmission  system and trading  markets in the  western and  northwestern
regions  of the  United  States and  western  Canada in order to exploit  market
inefficiencies  and maximize our profits in our fuel marketing  businesses.  Our
fuel marketing  operations require effective  management of price,  counterparty
and  operational  risks.  To mitigate  these  risks,  we have  implemented  risk
management  policies and  procedures  for each of our marketing  companies  that
prohibit  speculative  strategies  and  establish  price risk  exposure  levels,
counterparty  credit  limits  and  committees  to  monitor  compliance  with our
policies.  We also  limit  exposure  to energy  marketing  risks by  maintaining
separate credit  facilities for each of our marketing  companies and by avoiding
the issuance of parent company  performance  guarantees to counterparties of our
marketing companies.




Build and Maintain Strong  Relationships  with Wholesale  Energy  Customers.  We
strive to build strong  relationships  with utilities,  municipalities and other
wholesale customers, who we believe will continue to be the primary providers of
electricity to retail customers in a deregulated environment. We further believe
that these  entities  will need  products,  such as capacity,  in order to serve
their customers reliably. By providing these products under long-term contracts,
we are able to meet our customers' energy needs. Through this approach,  we also
believe we can earn more stable  revenues and greater returns over the long term
than we could by selling energy into the more volatile spot markets.

We have been successful in entering into a variety of wholesale  contracts based
on the specific needs of our  customers.  For example,  in 1999,  Public Service
Company of Colorado approached us to take over ownership and construction of the
120 megawatt Arapahoe and Valmont facilities in Colorado. Public Service Company
of Colorado was subject to regulatory constraints that restricted its ability to
own the  facilities  and needed the plants  completed in an efficient and timely
manner to meet the rapid  growth in demand.  We  completed  construction  of the
facilities  on  schedule,  and signed  tolling  agreements  with Public  Service
Company of  Colorado  for the  capacity  and energy  generated  by the  original
facilities.  We  subsequently  signed  agreements  to expand the  projects by 90
megawatts.  In  addition,  we recently  acquired  240  megawatts at the Fountain
Valley site in Colorado which we expect to be in service in 2001. We have signed
tolling  agreements  with Public  Service  Company of Colorado  for the expanded
facilities and the Fountain Valley site.

Capitalize On Our  Utility's  Established  Market  Presence,  Relationships  and
Customer Loyalty.  As a result of its firmly  established  market presence,  our
electric  utility has built solid brand  recognition and customer loyalty in the
Black Hills region.  By ensuring a reliable supply of power to retail  customers
in our South  Dakota and Wyoming  service  territory at rates below the national
average,  we have developed a strong,  supportive  relationship with our utility
regulators. Our utility provides a solid foundation of support for the expansion
of our independent energy and communications businesses. In addition,  industry,
technical  and market  expertise  from our  utility  supports  the growth of our
independent  energy businesses,  and our strong brand recognition  assists us in
achieving rapid customer  acceptance of our bundled  communications  services in
our Black Hills service territory.

Independent Energy

Our  independent  energy group  engages in the  production  and sale of electric
power through  ownership of a diversified  portfolio of generating  plants,  the
production of coal,  natural gas and crude oil  primarily in the Rocky  Mountain
region,  and the marketing of fuel products  nationwide.  The independent energy
group was our primary  source of revenue  and net income  growth in 2000 and the
net income from the  independent  energy  group is expected to exceed net income
from our  regulated  utility  beginning in 2001.  The  independent  energy group
consists of three units: independent power production,  fuel production and fuel
marketing.

Independent  Power  Production.   Our  independent  power  production   business
acquires,  develops  and  expands  unregulated  power  plants.  We hold  varying
interests  in  operating  independent  power  plants  in  California,  New York,
Massachusetts and Colorado with a total net ownership of 210 megawatts,  as well
as  minority  interests  in several  power-related  funds  with a net  ownership
interest of 40 megawatts.

Project Development  Program. In February 2001, we signed a definitive agreement
with Enron  Corporation to purchase 100 percent of an independent  power project
under  construction near Colorado  Springs,  Colorado and known as the "Fountain
Valley" project. We expect to close this transaction on or about March 31, 2001.
This site will initially  house 240 megawatts of gas-fired  peaking  facilities.
The energy and capacity generated by the Fountain Valley project will be sold to
Public  Service  Company of Colorado under a tolling  contract  expiring in July
2012  pursuant  to which we assume no fuel cost risk.  We expect the plant to be
completed  in phases  beginning  in June  2001 and  ending in July 2001 with the
total cost  expected to  approximate  $175  million.  In addition to the current
project,  we believe that the Fountain  Valley site provides us with  attractive
expansion and  integration  opportunities  and is  well-situated  to serve other
markets in the Rocky Mountain and southwest regions.



In addition to Wygen I and the Fountain Valley development, other projects under
construction include:

o    Arapahoe  CC5, a 50 megawatt  combined  cycle  expansion  of our  gas-fired
     turbines at the Arapahoe site located in the Front Range of Colorado;

o    Valmont  Unit 8, a 40 megawatt  gas-fired  turbine  addition to our Valmont
     site located in the Front Range of Colorado;

o    Black  Hills  Generation  Gillette  CT, a 40  megawatt  gas-fired  facility
     located at the same site as our Wygen I plant; and

o    Harbor  Expansion,  a 30 megawatt  (10  megawatt  net  ownership  interest)
     expansion  of our  Harbor  Cogeneration  facility  located  in  Wilmington,
     California.

We also have an active acquisition and development  program through which we are
pursuing  a number  of  additional  generation  projects  in  various  stages of
development, including the following:

o    the Lange project,  a 40 megawatt gas-fired turbine to be located either at
     the same site as our  Wygen I and Black  Hills  Generation  CT plants  near
     Gillette,  Wyoming,  or adjacent to our transmission  system in Rapid City,
     South Dakota, and which we expect to compete in early 2002;

o    a coal-fired  mine-mouth power plant with generating  capacity of up to 500
     megawatts,  to be located at our Wyodak site near Gillette,  Wyoming, which
     we expect to complete in 2005;

o    three separate  projects in early stage  development  with a total of 1,100
     megawatts of generation to be located at sites we currently own in whole or
     in part; and

o    four  additional  early stage  development  projects  with a total of 1,340
     megawatts of generation at new sites which we do not currently control.

No assurance can be given that we will be successful in completing any or all of
the projects currently under consideration.

How We Manage Our Portfolio.  We strive to maintain  diversification and balance
in our  portfolio of regulated  and  unregulated  power  plants.  Our  portfolio
(including  plants  currently   operating  and  those  under   construction)  is
diversified in terms of fuel mix and geographic location, with 81 percent of net
unregulated capacity being gas-fired,  13 percent coal-fired,  and the remainder
hydroelectric.  Our independent power plants are located in California, Wyoming,
South Dakota,  Colorado,  New York and Massachusetts.  In contrast, our electric
utility  capacity  is  approximately  53 percent  coal-fired,  33 percent oil or
gas-fired,  and 14 percent under purchased power contracts,  with plants located
in South Dakota and Wyoming.

We also have a diversified mix of revenue  sources.  We typically sell two types
of products: energy and capacity,  including ancillary services.  Although these
are separate  products,  both are typically sold together.  Energy refers to the
actual  electricity  generated by our facilities for ultimate  transmission  and
distribution to consumers of electricity. Energy is the only one of our products
that is subsequently  distributed to consumers.  Capacity refers to the physical
capability of a facility to produce  energy.  Ancillary  services  generally are
capacity support products used to ensure the safe and reliable  operation of the
electric power supply system. Examples of ancillary services include:

o    automatic  generation control,  which is used to balance energy supply with
     energy demand, referred to in our industry as "load," on a real-time basis;
     and

o    operating reserves,  which are used on an hourly or daily basis to generate
     additional  energy if demand increases or if major generating  resources go
     off-line or if transmission facilities become unavailable.



Our output is sold under  contracts  of varying  length and  subject to merchant
pricing,  thereby  allowing  us to take  advantage  of current  favorable  price
trends,  while  hedging  the  impact of a  potential  downturn  in prices in the
future.  We currently sell energy and capacity under a combination of short- and
long-term  contracts as well as direct sales into the merchant  energy  markets.
Currently,  we sell 70  percent  to 80  percent  of our  unregulated  generating
capacity in operation under contracts greater than one year in duration. We sell
the remainder of this capacity under  short-term  contracts or directly into the
merchant markets.  The energy and capacity generated by our Arapahoe and Valmont
projects,  and the additional energy and capacity expected at these sites and at
our  Fountain  Valley  project  upon its  completion,  are subject to  long-term
tolling  agreements  with Public  Service  Company of Colorado.  Similarly,  the
electricity  generated by the Adirondack Hydro facilities in New York is under a
combination of short- and long-term agreements with Niagara Mohawk.

How We Develop and Acquire Power Plants.  We plan to actively pursue power plant
acquisitions  and  development  opportunities  in  areas  we view as  attractive
throughout  North America.  Our current focus has been, and is likely to remain,
in the North American  Reliability  Council region known as the Western  Systems
Coordinating  Council,  or "WSCC." Among those  factors we consider  critical in
evaluating the relative  attractiveness of new generation  opportunities are the
following:

o    electric demand growth potential in the targeted region;

o    requirements for permitting and siting;

o    proximity of the proposed site to high transmission capacity corridors;

o    fuel supply reliability and pricing;

o    the local regulatory environment; and

o    the  potential  to exploit  market  expertise  and  operating  efficiencies
     relating to geographic  concentration  of new generation  with our existing
     power plant portfolio.

We intend to target both acquisition and development opportunities which provide
a minimum expected return on equity of 12 to 13 percent.  We plan to concentrate
on development  projects over  acquisitions  because we believe that development
projects generally offer us opportunities for higher rates of return.

Our goal is to sell approximately 80 percent of the independent power generation
portfolio under long-term  contracts,  while leaving the remainder available for
merchant,  or "spot" sales. We aim to secure  long-term power sales contracts in
conjunction with non-recourse plant financing.  This enables us to design a debt
repayment  schedule to closely  match the term of the power sales  contracts  so
that at the end of the contract term, the debt has typically been repaid.



Independent Power Plants

General. Power facilities are often classified by cost of production. Facilities
that have the lowest costs of  production  relative to other power plants in the
region are usually the facilities that are first used to provide  energy.  These
plants are known as "baseload"  facilities  and  typically  operate more than 60
percent of the time they are available. Our hydroelectric assets in New York and
the Wygen I coal-fired  facility under  construction  in Wyoming are examples of
low-cost, baseload plants.

As demand for  electricity  rises during the year or even during the course of a
day,  power plants that have higher costs of production are dispatched to supply
additional energy.  Facilities that regularly provide additional energy during a
day and that are  typically  used  between 10 percent and 60 percent of the time
are known as "intermediate" facilities.

Power plants with the highest costs of production  are called upon only in times
of exceptionally high demand and are known as "peaking units." Peaking units are
generally dispatched less than 10 percent of the time they are available.

Rocky Mountain and West Coast Facilities.  We own approximately 151 megawatts of
generating  capacity in the WSCC states of California  and Colorado,  and are in
the process of  constructing  or acquiring  another 470 megawatts in the region.
All of these  facilities  in operation  are  gas-fired,  with all but our Harbor
Cogeneration  facility in California operating under long-term power purchase or
tolling  agreements.  The Harbor  Cogeneration  facility currently operates as a
merchant peaking plant selling ancillary services and energy into the California
market.

Arapahoe, Valmont and Fountain Valley Facilities

In Operation: Our Arapahoe and Valmont plants are wholly-owned gas-fired peaking
facilities  in the  Front  Range  of  Colorado,  with a  total  capacity  of 120
megawatts. The projects were acquired from Public Service Company of Colorado in
January  2000  jointly by the former  Indeck  Capital  and us, and were put into
service on June 1, 2000.  We sell all of the output from these  plants to Public
Service Company of Colorado under tolling contracts  expiring in May 2012. These
contracts  also cover the Fountain  Valley  project and the Arapahoe and Valmont
expansion projects described below.

Under  Construction:  We expect to increase  our capacity by 40 megawatts at the
Valmont  project by June 2001 and by 50 megawatts  at the Arapahoe  plant by May
2002.



The first  phase of our 240  megawatt  gas-fired  Fountain  Valley  facility  is
scheduled for completion in June 2001, with final completion  scheduled for July
2001.  The  Fountain  Valley site,  located in Colorado  has ample  capacity for
subsequent expansion if market conditions prove to be attractive.

Wygen I Facility

The  Wygen I  facility  is a leased  mine-month  coal-fired  plant  with a total
capacity of 90 megawatts,  which is expected to be completed by spring 2003. The
Wygen  I  plant  will be  substantially  identical  in  design  to our  electric
utility's Neil Simpson II facility,  completed in 1995. The two plants will both
run on pulverized low-sulfur coal fed by conveyor from our adjacent Wyodak mine.
The plant will burn  approximately  500,000 tons of coal per year,  and will use
the latest available  environmental  control  technology.  We intend to sell the
majority of the power from the facility under long-term unit contingent capacity
and energy sales  contracts,  under which delivery is not required  during plant
outages. We have entered into a contract to sell 60 megawatts of unit contingent
capacity from this plant to Cheyenne  Light,  Fuel and Power Company with a term
of 10 years from the date the plant becomes  operational.  We have also signed a
contract to sell an  additional  20  megawatts of unit  contingent  capacity and
energy to the Municipal Electric Agency of Nebraska for a term of 10 years.

Black Hills Generation Gillette CT

The Black Hills Generation Gillette CT facility,  a gas-fired combustion turbine
facility located at the same site as our Wygen I facility,  has a total capacity
of 40 megawatts and is scheduled to be completed in May 2001. We plan to utilize
this facility as a merchant  plant through  summer 2001.  Beginning in September
2001, we will sell the energy and capacity from this facility to Cheyenne Light,
Fuel and Power Company under a 10-year unit contingent tolling agreement.

Ontario Cogeneration Facility

Ontario Cogeneration Company is a 12 megawatt, gas-fired power plant in Ontario,
California,  which is currently being operated as a baseload  plant.  Electrical
output  from the plant is subject to a 25-year  power  purchase  agreement  with
Southern California Edison which expires in January 2010. The project also sells
all of its steam production to Sunkist Growers, Inc. under a five-year agreement
which  terminates in November 2002. For a description of certain issues relating
to   our   operation   of   this   plant,    see    "--Regulation--Environmental
Regulation--Clean Air Act."

Harbor Cogeneration Facility

In Operation:  Harbor  Cogeneration,  a gas-fired  plant located in  Wilmington,
California,  is currently  being  operated as a merchant  peaking  plant selling
ancillary  services and energy into the California  Independent System Operator,
or  "CAISO,"  market.  It  formerly  operated  under a  30-year  power  purchase
agreement with Edison Mission  Energy.  This contract was terminated in February
1999 under a settlement  agreement with Southern  California  Edison.  Under the
buyout  agreement,  Harbor  Cogeneration  will  receive  payments  pursuant to a
termination  payment schedule for an amount equal to the total payment under the
original  contract due for the 11-year period beginning April 1, 1997 and ending
on October 1, 2008. The facility currently has no long-term debt outstanding.

Under Construction/Expansion: We are currently expanding the Harbor Cogeneration
plant by an additional 30 megawatts (10 megawatt net ownership interest), with a
targeted  completion  date of May 2001. The plant has sold the peaking  capacity
from its expansion to the CAISO for the peak summer periods of 2001 through 2003
under an agreement  that  provides for payments to us of $1 million per year for
each of 2001,  2002 and 2003. We plan to sell the remaining  capacity and all of
the energy from this plant in the California market on a merchant basis.



Lange Project

In March 2001, we placed an order for a 40 megawatt gas-fired combustion turbine
which  will be  located  either  adjacent  to the  Wygen I and our  Black  Hills
Generation Gillette CT plants near Gillette,  Wyoming, or at a new site adjacent
to our transmission  system in Rapid City, South Dakota,  where we have received
all necessary permits for the construction of two 40 megawatt combustion turbine
facilities.  We expect the first 40 megawatt  turbine unit to be  operational in
early 2002.

Northeast  Facilities.  We  currently  own  approximately  58 net  megawatts  of
generation  capacity in eight plants in the Northeast  region,  all of which are
located in New York and Massachusetts. Sixty-seven percent of this generation is
"run-of-river"  hydroelectric,   with  the  remainder  being  gas-fired  peaking
capacity.

Adirondack Hydro Development

     The  seven  "run-of-river"  hydroelectric  plant  interests  acquired  as a
     result of our acquisition of Indeck Capital are:

          o    New York State Dam, an 11.4  megawatt  plant located in Waterford
               and Cohoes, New York;

          o    Middle Falls, a 2.3 megawatt plant located in Easton, New York;

          o    Sissonville, a 3.0 megawatt plant located in Potsdam, New York;

          o    Warrensburg,  a 2.9 megawatt  plant located in  Warrensburg,  New
               York;

          o    Hudson Falls, a 41.9 megawatt plant located in Moreau, New York;

          o    South Glens Falls,  a 13.9 megawatt  plant located in South Glens
               Falls, New York; and

          o    Fourth  Branch,  a 3.4 megawatt  plant located in Waterford,  New
               York.

We  acquired  approximately  10 percent of the Hudson  Falls and the South Glens
Falls plants as part of the Indeck  Capital  acquisition  and an  additional  20
percent of these plants in December 2000.  These projects run at a high capacity
factor  because the Hudson River is  regulated  for power  generation  and flood
control.


The seven projects were initially covered by long-term power purchase  contracts
with Niagara Mohawk for all or most of their output.  Currently,  three projects
have been  restructured  to allow the power purchase  contracts to be bought out
and for us  eventually  to sell  power  into  the New  York  Independent  System
Operator  (NY-ISO).  The New York  State  Dam,  Sissonville,  Fourth  Branch and
Warrensburg  facilities  are currently  subject to short-term  transition  power
sales  agreements  expiring in 2002 and 2003,  at which point these  plants will
sell directly into the market on a merchant basis.  The remaining three New York
plants,  Hudson Falls,  South Glens Falls and Middle Falls,  continue to operate
under long-term power purchase agreements with Niagara Mohawk.

Pepperell Facility

The Pepperell facility is a 40 megawatt gas-fired  combined-cycle  plant located
in  Pepperell,  Massachusetts.  The  plant is  currently  subject  to a  tolling
agreement  with Enron Power and Trading for the sale of a majority of its energy
for the year 2001, and a steam sales  agreement with the Pepperell Paper Company
expiring in November 2001.

Power Funds. In addition to our ownership of the power plants  described  above,
we hold various  indirect  interests in power plants  through our  investment in
energy and energy-related  funds, both domestic and international,  as described
below:

Financing of Our  Independent  Power  Projects.  We have  financed our principal
independent power generation facilities primarily with non-recourse debt that is
repaid solely from the project's revenues. This type of financing is referred to
as "project  financing." These financings  generally are secured by the physical
assets,  major project  contracts and agreements,  cash accounts and, in certain
cases, our ownership interest, in the related project. True project financing is
not  available  for  all  projects,  including  some  assets  purchased  out  of
bankruptcy,  some merchant plants and some purchases of minority stock positions
in publicly-traded companies. Even in those instances,  however, we may still be
able to finance a smaller portion of the total cost with project financing, with
the  remainder  financed  with debt that is either  raised or  supported  at the
corporate rather than the project level.

Project financing  transactions generally are structured so that all revenues of
a project are  deposited  directly  with a bank or other  financial  institution
acting as escrow or security  deposit  agent.  These funds then are payable in a
specified order of priority set forth in the financing documents to ensure that,
to the extent available,  they are used first to pay operating expenses,  senior
debt  service and taxes and to fund  reserve  accounts.  Thereafter,  subject to
satisfying debt service coverage ratios and certain other conditions,  available
funds may be disbursed  for  management  fees or  dividends  or, where there are
subordinated lenders, to the payment of subordinated debt service.

These  project  financing  structures  are  designed to prevent the lenders from
relying  on  us  or  our  other  projects  for  repayment;  that  is,  they  are
"non-recourse"  to us and our affiliates not involved in the project,  unless we
or another affiliate expressly agree to undertake  liability.  In the event of a
foreclosure  after a default,  our project  affiliate  owning the facility would
only retain an interest in the  assets,  if any,  remaining  after all debts and
obligations  were paid.  In  addition,  the debt of each  operating  project may
reduce the liquidity of our equity interest in that project because the interest
is  typically  subject  both to a  pledge  securing  the  project's  debt and to
transfer restrictions set forth in the relevant financing agreements.  Also, our
ability to transfer or sell our  interest in certain  projects or the  project's
power is  restricted by certain  purchase  options or rights of first refusal in
favor of our partners and certain change of control  restrictions in the project
financing documents.



Fuel Production

Coal

Our coal production segment mines and processes  low-sulfur  sub-bituminous coal
near  Gillette,  Wyoming.  The  Wyodak  mine,  which we  acquired  in 1956  from
Homestake Gold Mining Company,  is located on top of the Powder River Basin, one
of the largest coal reserves in the United States. We believe the Wyodak mine is
the oldest operating surface coal mine in the nation,  with an annual production
of approximately three million tons. Mining rights to the coal are based on four
federal  leases and one state  lease.  We pay  royalties of 12.5 percent and 9.0
percent, respectively, of the selling price on all federal and state coal. As of
December 31, 2000, we had coal  reserves of 275 million tons,  enough to satisfy
present contracts for over 90 years. Substantially all of our coal production is
sold under long-term contracts to Black Hills Power, Inc., our electric utility,
and to PacifiCorp.

Our coal  segment's  agreement  with Black Hills Power limits  earnings from all
coal sales to Black  Hills  Power to a  specified  return on our  original  cost
depreciated  investment  base.  Black Hills Power made a commitment to the South
Dakota Public Utilities  Commission,  the Wyoming Public Service  Commission and
the City of Gillette that coal would be furnished and priced as provided by that
agreement for the life of our Neil Simpson II plant.

The price for unprocessed coal sold to PacifiCorp for its 80 percent interest in
the Wyodak Plant is determined by a coal supply  agreement  terminating in 2013.
For a description of litigation with PacifiCorp relating to this agreement,  see
"ITEM 3. LEGAL PROCEEDINGS - PacifiCorp Litigation."

In May 2000, we acquired the K-Fuel plant, a coal enhancement plant located near
our Gillette,  Wyoming coal mine.  The plant,  which  transforms  high-moisture,
low-heat-value coal into low-moisture, high-heat-value coal, is currently not in
service.  We are working in conjunction with  Denver-based  KFx, Inc. to attract
investors to make the capital  improvements  necessary to re-start the plant. If
we do not locate suitable investment partners, the plant will not be re-started.

Over the next several years, we expect to increase coal production to supply:

o    the Wygen I 90 megawatt  mine-mouth  power plant,  which is  scheduled  for
     completion in 2003; and

o    additional  mine mouth  generating  capacity of up to 500  megawatts at the
     same  site  as  the  Wygen  I  plant,  which  is in  the  early  stages  of
     development.

In addition, if our K-Fuel plant is re-started, we expect to increase production
from the Wyodak  mine and market any  low-moisture,  high-heat  content  coal we
produce to an expanded customer base.

Natural Gas and Crude Oil

Our oil and gas exploration and production  segment operates  approximately  298
oil and gas wells,  all of which are located in Wyoming.  The  majority of these
wells  are in the  Finn-Shurley  Field  area,  located  in Weston  and  Niobrara
Counties in Wyoming.  We also own a working interest in, but do not operate,  an
additional  341 wells  located in  California,  Montana,  North  Dakota,  Texas,
Wyoming,  Oklahoma  and  offshore in the Gulf of Mexico.  In  addition,  we have
accumulated  significant acreage in the Rocky Mountain region,  which we plan to
utilize for oil and gas exploration.



We  plan to  substantially  increase  our  natural  gas  reserves  and  minimize
exploration risk by focusing on lower-risk  exploration and development drilling
and  acquisitions  of  proven  producing  properties.  A key  component  of this
strategy  is the  pursuit of shallow  gas  opportunities  in the Rocky  Mountain
region.  We also  expect  to  modestly  increase  our  California  and  offshore
production  in the future,  but do not plan to serve as the  operator  for those
production activities.

As of December 31, 2000,  we had proved  reserves of 4.4 million  barrels of oil
and 18.4 billion  cubic feet of natural gas,  with  approximately  62 percent of
current  production  consisting  of  natural  gas.  In  2000,  our  oil  and gas
production  increased 12 percent over 1999 levels,  with record drilling results
and year-end reserves.

In March 2001, we signed a definitive  agreement to purchase  certain  operating
and  non-operating  interests  in 74 oil  and gas  wells  located  primarily  in
Colorado and Wyoming.  We expect this  transaction to close in April 2001. These
properties  have proved  reserves  of  approximately  8.7 billion  cubic feet of
natural gas and approximately  200,000 barrels of oil,  representing an increase
in our existing proved reserves of over 20 percent.

Fuel Marketing.  We market natural gas, oil and coal in specific  regions of the
United  States.  We offer  physical and financial  wholesale  fuel marketing and
price risk  management  products and services to a variety of  customers.  These
customers include natural gas distribution companies, municipalities, industrial
users, oil and gas producers,  electric utilities,  coal mines, energy marketers
and  retail  gas  users.  Our fuel  marketing  businesses  collectively  have 35
employees.  Our average daily marketing  volumes for the year ended December 31,
2000,  were 860,800  million British thermal units of gas, 44,300 barrels of oil
and 4,400 tons of coal.

The  following  table  briefly  summarizes  the  location of our fuel  marketing
operations and sales offices:

Gas Marketing

Our natural gas marketing operations are headquartered in Golden, Colorado, with
satellite offices in Calgary,  Canada and Chicago,  Illinois.  Our gas marketing
operations  focus  primarily  on  wholesale  marketing  and  producer  marketing
services.  Producer  services include providing for direct purchases of wellhead
gas and for risk transfer and hedging  products.  Our gas marketing  efforts are
concentrated in the Rocky Mountain and West Coast regions and in Western Canada,
which are areas in which we believe we have a  competitive  advantage due to our
knowledge of local markets.  We contractually  hold natural gas storage capacity
and both long and short-term  transportation capacity on several major pipelines
in the  western  United  States and  Canada.  We utilize  this  capacity to move
relatively  low cost  natural gas from the  producer  regions to more  expensive
end-use market areas.

Oil Marketing and Transportation

Our crude oil marketing and transportation operations are concentrated primarily
in Texas,  Oklahoma,  Louisiana  and  Arkansas.  In July 1999,  we acquired a 33
percent  ownership  interest in a 200-mile  pipeline,  with a capacity of 67,000
barrels of oil per day, that transports imported crude oil from Beaumont,  Texas
to refining and trading markets in northern regions.




Coal Marketing

We  market  coal to  various  industrial  customers  and  power  plants  located
primarily in the midwest and eastern  regions of the United  States  through our
coal marketing subsidiary,  Black Hills Coal Network. We formed Black Hills Coal
Network in 1998 to acquire  the assets and hire the  operational  management  of
Coal Network and Coal Niche, based in Mason,  Ohio. These predecessor  companies
were coal brokerage and agency companies with customers  located  primarily east
of the Mississippi River.

Electric Utility - Black Hills Power, Inc.

Our  electric  utility,  Black  Hills  Power,  is  engaged  in  the  generation,
transmission and distribution of electricity.  It provides a solid foundation of
revenues,  earnings and cash flow that  support  utility  capital  expenditures,
dividends, and overall performance and growth.

Distribution   and   Transmission.   Our  electric   utility   distribution  and
transmission  businesses serve approximately 58,600 electric customers,  with an
electric transmission system of 447 miles of high voltage lines and 541 miles of
lower voltage lines. Our utility's  service territory covers a 9,300 square mile
area of western South Dakota,  eastern Wyoming and  southeastern  Montana with a
strong and  stable  economic  base.  Over 90  percent  of our  utility's  retail
electric revenues are generated in South Dakota.

The  following  are   characteristics   of  our  distribution  and  transmission
businesses:

o    We have a diverse  customer  and revenue  base.  Our revenue mix in 2000 is
     comprised of 29 percent wholesale  off-system sales, 26 percent commercial,
     20  percent  residential,   14  percent  industrial,  10  percent  contract
     wholesale and 1 percent  municipal.  Approximately  68 percent of our large
     commercial and industrial  customers are provided  service under  long-term
     contracts.  We have  historically  optimized the  utilization  of our power
     supply resources by selling wholesale power to other utilities and to power
     marketers in the spot market and through short-term sales contracts.

o    In 1999, the South Dakota Public Utilities Commission extended our previous
     retail rate freeze for another  five-years,  through  January 1, 2005.  The
     rate freeze  preserves  our  low-cost  rate  structure  at levels below the
     national  average for our retail  customers while allowing us to retain the
     benefits from cost savings and from wholesale "off-system" sales, which are
     not  covered by the rate  freeze.  This  provides  us with  flexibility  in
     allocating our generating  capacity to maximize  returns in changing market
     environments.

o    Twenty-nine  percent of our electric  revenues for the year ended  December
     31, 2000 consisted of off-system  sales compared to 8 percent in 1999 and 5
     percent in 1998.  Further  increases in the volume of off-system  sales are
     expected in the future due to demand  growth in the Rocky  Mountain  region
     and  the  June  2000  addition  of 40  megawatts  of  gas-fired  generating
     capacity.

o    Our system has the  capability of  connecting  to either the  midwestern or
     western  transmission  systems,  which  provides us with access between the
     WSCC region and the Mid-Continent  Area Power Pool, or "MAPP" region.  This
     allows us the opportunity to improve system  reliability and take advantage
     of power price differentials between the two electric grids. We are able to
     transmit up to 80 megawatts of our generation into the MAPP. Alternatively,
     we can receive up to 20  megawatts  of power from MAPP into our  WSCC-based
     system.  We expect to increase  this  capability  to 50  megawatts  in 2001
     through an upgrade of our facilities at a cost of less than $1 million.

o    We have firm transmission  access to deliver up to 65 megawatts of power on
     PacifiCorp's system to wholesale customers in the western region.


On  October  15,  2000,  we  indicated  to FERC our intent to  participate  in a
regional transmission organization, or RTO. Our transmission system is a part of
the western  transmission  grid  governed by the  Western  Systems  Coordinating
Council,  and it interconnects with transmission systems operated by the Western
Area  Power  Administration,  or WAPA,  and by  PacifiCorp.  WAPA is  evaluating
participation in the Desert Star RTO which will involve  transmission systems in
Colorado and the southwest region, while PacifiCorp is evaluating  participation
in the RTO West  which will  involve  transmission  systems  in Wyoming  and the
northwest  region.  Neither  Desert  Star RTO nor RTO  West  has  been  formally
organized at this time,  but we expect that Desert Star RTO and RTO West will be
making  their  final  FERC  filings  late  this year or in early  2002.  If FERC
approves these two RTOs, the organizations anticipate being fully operational in
late 2002.  We will  continue to monitor the  development  of these two RTOs and
decide in the future which RTO best fits our transmission system and operations.

Power Purchase  Agreements.  We sell  approximately  40 percent of our utility's
current load under  long-term  contracts.  Our key  contracts  include a 10-year
contract expiring in 2007 with Montana-Dakota  Utilities Company for the sale of
up to 55  megawatts  of energy and  capacity  to service the  Sheridan,  Wyoming
electric service territory,  and a contract with the City of Gillette,  Wyoming,
expiring  in 2012,  to provide the city's  first 23  megawatts  of capacity  and
energy. Both contracts are integrated into our control system and are treated as
firm native load. In addition,  we recently  entered into an agreement  with the
Municipal  Electric  Agency of  Nebraska  for the sale of 30  megawatts  of unit
contingent   energy  and  capacity  for  a  period  through  the  completion  of
construction  of the Wygen I independent  power  facility,  which is expected in
spring 2003. For the 10-year period beginning with the completion of the Wygen I
facility,  our  utility  and our  independent  power  unit will each  provide 20
megawatts  of unit  contingent  energy and  capacity to the  Municipal  Electric
Agency of Nebraska.

Our  utility's  electric  load is served by coal-,  oil- and  natural  gas-fired
generating  units  providing 393  megawatts of generation  capacity and from the
following purchased power and capacity contracts with PacifiCorp:

o    a power sales agreement  expiring in 2023,  involving the purchase by us of
     65  megawatts  of baseload  power in 2001,  and  scheduled to decline to 50
     megawatts by 2004;

o    a reserve  capacity  integration  agreement  expiring in 2012,  which makes
     available to us 100 megawatts of reserve  capacity in  connection  with the
     utilization of the Ben French CT units; and

o    a capacity  option  call,  which  gives us an option to  purchase  up to 60
     megawatts of peaking capacity seasonally through March 31, 2007.

Regulated  Power  Plants.  Since 1995,  our  utility has been a net  producer of
energy. Our utility owns 393 megawatts of generating  capacity,  all of which is
located in the Rocky  Mountain  region.  Our  utility's  peak system load of 372
megawatts  was reached in July 2000.  None of our  generation  is  restricted by
hours of operation,  thereby  providing us with the ability to generate power to
meet demand whenever necessary and feasible.

near Gillette,  Wyoming. Neil Simpson I has a capacity of 21.8 megawatts and was
put into service in 1969.  Neil Simpson II has a capacity of 88.9  megawatts and
was put into service in 1995. These plants are operated as baseload  facilities,
and are mine-mouth  coal-supplied plants, receiving their coal directly from the
Wyodak mine.

Osage

The Osage plant is a  wholly-owned  coal-fired  plant in Osage,  Wyoming  with a
total  capacity of 34.5  megawatts  and was put into  service from 1948 to 1952.
This  plant has three  turbine  generation  units,  and is being  operated  as a
baseload  plant.  Coal for the  plant is  purchased  from  our  Wyodak  mine and
delivered by truck.

Wyodak

Wyodak is a 362 megawatt mine mouth coal-fired plant owned jointly by PacifiCorp
and us and in which we hold a 20 percent (72.4 net megawatt) ownership interest.
Our Wyodak mine  furnishes  all the coal fuel supply for the Wyodak  plant.  The
plant  was put into  service  in 1978,  and is  currently  being  operated  as a
baseload plant.



Neil Simpson CT

The Neil Simpson  Combustion  Turbine is a wholly-owned  gas-fired plant located
near Gillette,  Wyoming with a capacity of 40 megawatts. This plant was put into
service in 2000, and was installed to provide peaking capabilities.

Communications

Our communications  group, known as Black Hills FiberCom,  was formed to provide
state-of-the-art  broadband   telecommunications  services  to  the  underserved
markets of Rapid City and the  northern  Black Hills of South  Dakota.  We offer
residential and business customers a full suite of telecommunications  services,
including local and long distance telephone  service,  expanded cable television
service,  cable modem Internet access and high speed data and video services. We
have  completed  a 210-mile  inter-  and  intra-city  fiber  optic  network  and
currently operate 588 miles of two-way interactive hybrid fiber coaxial or "HFC"
cable.  We believe  we are one of the first  companies  in the United  States to
provide video entertainment  service,  high-speed Internet access, and local and
long distance telephone services over an advanced broadband  infrastructure.  We
have bundled these services into value packages with a single  consolidated bill
for all of these services.

We  introduced  our  broadband  communications  services  to the Rapid  City and
northern  Black Hills areas in November  1999.  As of December 31, 2000,  we had
attracted 8,368 residential customers and 646 business customers. Our goal is to
double the number of our customers,  and to attain 50 percent residential market
penetration  within  our  service  territory  while  serving  35  percent of all
broadband business customers in that territory.

The  construction  of our  communications  network is  approximately  75 percent
complete  and we expect  to  substantially  complete  construction  in 2001.  We
estimate that completing our network will require  approximately  $25 million of
capital expenditures in 2001.

Competition

The  independent  power,  fuel  production  and fuel  marketing  industries  are
characterized by numerous strong and capable competitors, some of which may have
more  extensive  operating  experience,   larger  staffs  or  greater  financial
resources than us. In particular, the independent power industry in recent years
has  been  characterized  by  increased  competition  for  asset  purchases  and
development opportunities.

In  addition,   Congress  has  considered   various  pieces  of  legislation  to
restructure  the  electric  industry  that would  require,  among other  things,
customer choice and/or repeal of the Public Utility Holding Company Act of 1935,
or PUHCA. The debate is likely to continue and perhaps intensify.  The effect of
enacting  such  legislation  cannot be predicted  with any degree of  certainty.
Industry  deregulation may encourage the disaggregation of vertically integrated
utilities into separate generation, transmission and distribution businesses. As
a  result  of  these  potential  regulatory  changes,   significant   additional
competitors could become active in the generation segment of our industry.

Our  communications  unit  faces  competition  from  numerous  well  established
companies, including Qwest Communications, Rapid City's incumbent local exchange
carrier,  Midcontinent  Communications,  the area's  incumbent cable  television
provider, as well as long distance providers and Internet service providers. Our
success in this  business will depend upon,  among other things,  the quality of
our customer service,  the willingness of residential and business  customers to
accept us as an alternative provider of broadband  communications  services, our
products and services and our ability to offer an attractive  package of bundled
products.



Risk Management

Our fuel  marketing  operations  require  efficient  risk  management  of price,
counterparty  performance and operational  risks.  Price risk is created through
the volatility of energy prices.  Counterparty performance risk is the risk that
a  counterparty  will fail to satisfy  its  contractual  obligations  to us, and
includes credit risk.  Operational risk arises from a lack of internal controls.
We have implemented controls to mitigate each of these risks.

Our fuel  marketing  operations  are  conducted in  accordance  with  guidelines
established  through  separate risk management  policies and procedures for each
marketing company and through our credit policy.  These policies are established
by our  board of  directors,  reviewed  on a  regular  basis  and  monitored  as
described below.

We  maintain  a working  risk  management  committee  for each of our  marketing
companies,  and a  credit  committee  at the  parent  company  level.  The  risk
management  committees focus on implementation of risk management procedures and
on monitoring  compliance with established  policies.  The credit committee sets
counterparty  credit  limits,   monitors  credit  exposure  levels  and  reviews
compliance with  established  credit  policies.  Additionally,  we employ a risk
manager and a credit manager responsible for overseeing these functions.

Our risk management  policies and procedures specify maximum price risk exposure
levels  within  which each  respective  marketing  company must  operate.  These
policies and procedures  establish  relatively low exposure  levels and prohibit
speculative trading strategies.

As part of our enterprise-wide risk management  strategy,  we limit our exposure
to energy marketing risks by maintaining  separate credit facilities within each
of our fuel marketing companies. These credit facilities have security interests
solely  against  the  assets  of the  respective  marketing  company,  with  the
exception of a $1 million  guarantee by our coal mining  subsidiary  on our coal
marketing  unit's  credit  facility.  We do not currently  issue parent  company
performance guarantees to counterparties of our marketing companies.

A  significant  potential  risk related to power sales is the price risk arising
from the sale of wholesale  power that exceeds our  generating  capacity.  Short
positions  can arise from  unplanned  plant outages or from  unanticipated  load
demands.  To control  such risks,  we  restrict  wholesale  off-system  sales to
amounts by which our anticipated generation  capabilities exceed our anticipated
load  requirements  plus a required reserve margin. We further control this risk
by selling only in the day-ahead  power market and by entering into  longer-term
sales contracts that are made on a "unit contingent" basis, under which delivery
is not required during unplanned outages at specified power plants.

California Markets

In 1996, California enacted legislation restructuring the state's investor-owned
utilities.   The   legislation   instituted   a  freeze  on  retail  rates  that
investor-owned  utilities  could  charge their  customers  for the duration of a
transition period  established by the legislation.  The legislation did not make
any provision for a California utility to recover costs of purchased electricity
that  exceeded  the rates that could be charged  under the rate  freeze.  Due to
inadequate  supplies  of  power  and  an  unanticipated  surge  in  demand,  the
California  market has experienced rapid increases in electric power and natural
gas prices.  As a result,  the state's  two  largest  investor-owned  utilities,
Pacific Gas & Electric Company (PG&E) and Southern California Edison (SCE), have
incurred costs of procuring  power  significantly  in excess of their ability to
recover those costs through  authorized  retail rates and have  indicated  that,
unless the rate freeze is eliminated or other proposed relief is provided,  they
are, or shortly will become, insolvent.

We may experience  losses related to the potential  insolvency of the California
utilities in the event that a utility defaults on its obligations:

o    under its agreements with us;

o    to the  CAISO,  which  administers  the  real-time  markets  for energy and
     ancillary services, resulting in non-payment to us under our capacity sales
     agreement with the CAISO; or



o    to other energy  companies,  causing  those energy  companies to default on
     their  obligations  to us.

We have two  agreements  with SCE involving  our  California  independent  power
plants.

o    In 1999,  we entered into a settlement  agreement  with SCE  involving  the
     Harbor  Cogeneration plant located in Wilmington,  California,  in which we
     own a 31.8 percent  interest.  The  settlement  agreement  provides for the
     termination of a 30-year power purchase agreement, in exchange for payments
     of  approximately  $4 million per year by SCE through  October 2008 for our
     interest in the plant.

o    The  cogeneration  plant  located in  Ontario,  California  is  entitled to
     receive energy and capacity payments from SCE of approximately $1.7 million
     per year, under a long-term contract expiring in 2010.

As of  March  1,  2001,  SCE owed us past due  payments  of  approximately  $1.5
million,  with delinquencies  ranging from 15 to 75 days in duration. We have no
other material  contractual  relationships  with SCE and no material  agreements
with PG&E.

The Harbor  Cogeneration  plant has sold the peaking capacity from its expansion
to the CAISO for the peak summer periods of 2001 through 2003 under an agreement
that  provides for payments to us of $1 million per year for each of 2001,  2002
and 2003. We have no other  agreements  with the CAISO and do not otherwise sell
capacity and energy directly into the California market either through long-term
contracts or on a merchant  basis.  All other  merchant  sales are made to power
marketers who in turn sell into the  California  market.  In addition,  our fuel
production  and fuel marketing  exposure to the  California  market is primarily
indirect  through sales to creditworthy  counterparties,  including  neighboring
utilities and gas and power marketing firms.

In recent months,  the Governor of the State of California,  representatives  of
the state legislature and numerous industry participants have undertaken several
initiatives  designed to address market  disruptions in California.  In February
2001,  SCE reached a tentative  agreement  under which the state would pay $2.76
billion to purchase SCE's high voltage  transmission system and SCE would drop a
federal lawsuit in which it has sought  authority to bill its customers for past
unrecovered costs. Prior to its implementation,  this agreement must be approved
by the California state legislature.  There is no assurance that any legislation
will be  enacted or that,  if  enacted,  the sale of  transmission  assets  will
provide SCE with  sufficient  funds to pay any current or future  obligations to
us. In addition,  there is no assurance  that any current or future  defaults by
California  utilities on obligations  owed to others will not result in defaults
by our counterparties. However, we believe that our direct exposure to potential
defaults in the California  market is largely limited to the agreements with SCE
and the CAISO described above and that our indirect exposure is minimal.

Regulation

We are  subject  to a broad  range  of  federal,  state  and  local  energy  and
environmental laws and regulations applicable to the development,  ownership and
operation of our projects.  These laws and regulations  generally require that a
wide variety of permits and other approvals be obtained  before  construction or
operation of a power plant commences and that,  after  completion,  the facility
operate in  compliance  with their  requirements.  We strive to comply  with the
terms of all such laws,  regulations,  permits and licenses and believe that all
of our  operating  plans are in  material  compliance  with all such  applicable
requirements.

Energy Regulation

Federal  Power  Act.  The  Federal  Power Act gives FERC  exclusive  rate-making
jurisdiction  over  wholesale  sales  of  electricity  and the  transmission  of
electricity  in  interstate  commerce.  Pursuant to the Federal  Power Act,  all
public  utilities  subject  to FERC's  jurisdiction  are  required  to file rate
schedules  with FERC prior to  commencement  of  wholesale  sales or  interstate
transmission of electricity. Public utilities with cost-based rate schedules are
also  subject  to   accounting,   record-keeping   and  reporting   requirements
administered by FERC.



The Energy  Policy  Act.  The passage of the Energy  Policy Act in 1992  further
encouraged  independent  power production by providing  certain  exemptions from
regulation for exempt  wholesale  generators,  or EWGs. All of our  subsidiaries
that would  otherwise be treated as public  utilities are  currently  treated as
EWGs  under the  Energy  Policy  Act.  An EWG is an entity  that is  exclusively
engaged,  directly  or  indirectly,  in the  business  of  owning  or  operating
facilities  that are  exclusively  engaged in  generation  and selling  electric
energy at wholesale. An EWG will not be regulated under PUHCA, but is subject to
FERC and state public  utility  commission  regulatory  reviews,  including rate
approval.  Since EWGs are only allowed to sell power at  wholesale,  their rates
must receive initial approval from FERC rather than the states.  All of our EWGs
to date that have sought rate approval from FERC have been granted  market-based
rate authority,  which allows FERC to waive certain  accounting,  record-keeping
and reporting  requirements  imposed on public utilities with cost-based  rates.
However,  FERC  customarily  reserves  the  right to  suspend,  upon  complaint,
market-based  rate  authority  on a  prospective  basis  if it  is  subsequently
determined  that we or any of our EWGs exercised  market power.  If FERC were to
suspend market-based rate authority,  it would most likely be necessary to file,
and obtain FERC  acceptance of,  cost-based  rate schedules for any of our EWGs.
Also,  the loss of  market-based  rate  authority  would subject the EWGs to the
accounting, record-keeping and reporting requirements that are imposed on public
utilities with cost-based rate schedules.

In addition,  if there occurs a "material change" in facts that might affect any
of our subsidiaries'  eligibility for EWG status, within 60 days of the material
change, the relevant EWG must (1) file a written explanation of why the material
change  does not  affect  its EWG  status,  (2) file a new  application  for EWG
status,  or (3) notify FERC that it no longer wishes to maintain EWG status.  If
any of our subsidiaries were to lose EWG status,  we, along with our affiliates,
would be subject to regulation under PUHCA as a public utility company. Absent a
substantial  restructuring  of our  business,  it would be  difficult  for us to
comply with PUHCA without a material adverse effect on our business.

State Energy Regulation.  In areas outside of wholesale rate regulation (such as
financial or organizational regulation),  some state utility laws may give their
public utility commissions broad jurisdiction over steam sales or EWGs that sell
power in their service  territories.  The actual scope of the jurisdiction  over
steam  or  independent   power   projects   depends  on  state  law  and  varies
significantly from state to state.

Environmental Regulation

The  construction  and  operation  of power  projects  are subject to  extensive
environmental  protection and land use  regulation in the United  States.  These
laws and  regulations  often require a lengthy and complex  process of obtaining
licenses,  permits and approvals from federal, state and local agencies. If such
laws and  regulations  are changed  and our  facilities  are not  grandfathered,
extensive   modifications  to  project  technologies  and  facilities  could  be
required.

General.  Based on current  trends,  we expect that  environmental  and land use
regulation  will  continue to be  stringent.  Accordingly,  we  actively  review
proposed  construction  projects  that could  subject us to stringent  pollution
controls imposed on "major  modifications,"  as defined under the Clean Air Act,
and changes in  "discharge  characteristics,"  as defined  under the Clean Water
Act.  The  goal of  these  actions  is to  achieve  compliance  with  applicable
regulations,   administrative  consent  orders  and  variances  from  applicable
air-quality related regulations.

Clean Air Act.  Our Neil  Simpson II and  Wyodak  plants  located  in  Gillette,
Wyoming are  subject to Title IV of the Clean Air Act,  which  requires  certain
fossil-fuel-fired  combustion  devices to hold sulfur dioxide  "allowances"  for
each ton of sulfur  dioxide  emitted.  We currently hold  sufficient  allowances
credited to us as a result of sulfur removal equipment  previously  installed at
the Wyodak plant to apply to the  operation of the Neil Simpson II plant and our
interest in the Wyodak plant through 2030 without  requiring the purchase of any
additional allowances. With respect to any future plants, we plan to comply with
the need for holding the  appropriate  number of allowances  by reducing  sulfur
dioxide  emissions  through the use of low sulfur fuels,  installation  of "back
end" control  technology  and the purchase of allowances on the open market.  We
expect to integrate  the costs of obtaining  the required  number of  allowances
needed for future projects into our overall financial analysis of such projects.



On July 14,  2000,  the South Coast Air Quality  Management  District,  known as
SCAQMD, sent a letter to our affiliate,  now called Black Hills Ontario, L.L.C.,
the operator of a 12 megawatt natural-gas fired cogeneration facility located in
Ontario,  California,  stating that the SCAQMD had determined,  as a result of a
facility audit  completed for the compliance  year ended June 1, 1999,  that the
facility's  nitrogen  oxide,  or NOx,  emissions  were  28,958  pounds  over the
facility's NOx allocation  established by the SCAQMD's RECLAIM emissions trading
program.  As a  result,  the  SCAQMD  indicated  that it would be  reducing  the
facility's  NOx  allocation by the same number of allowances  for the compliance
year subsequent to a final determination on this issue. If a final determination
is reached prior to June 30, 2001, the NOx allowances would be deducted from the
facility's  allocation for the compliance year ended June 30, 2002.  Black Hills
Ontario  has  provided  documentation  to the  SCAQMD  disputing  this  proposed
reduction.  In  addition to this  proposed  reduction,  which  could  affect the
facility's  compliance with RECLAIM  requirements  for the 2001-2002  compliance
period,  Black  Hills  Ontario  also  projects  that its NOx  emissions  for the
compliance year ended June 30, 2001 may be approximately  30,000 pounds over its
current NOx allocation.  There is currently significant  volatility in the price
and supply of  RECLAIM  NOx  allowances;  although  the  SCAQMD  has  proposed a
revision to its  regulations  to  stabilize  the RECLAIM  market,  it is unclear
whether these rules will mitigate Black Hills Ontario's  potential  exposure for
its projected  allowance  shortfall.  Accordingly,  no assurance can be given at
this time  regarding  whether  RECLAIM  NOx  allowances  will be  available  for
purchase to allow Black Hills  Ontario to comply with RECLAIM  requirements  for
the year ended June 30, 2001, or, if allowances are available, as to the cost of
those  allowances.  Black Hills Ontario may also be subject to administrative or
civil  penalties with respect to alleged  violations of the SCAQMD's  regulation
for the  compliance  year  ended  June 30,  1999,  although  no  notice  of such
penalties has been issued.

In July 1999, the United States Environmental  Protection Agency (EPA) finalized
rules designed to protect and improve visibility  impairment  resulting from air
emissions.  Among other  things,  the  regulations  required  states to identify
sources of  emissions  (including  certain  coal-fired  generating  units  built
between 1962 and 1977) by 2004 that would be subject to "Best Available Retrofit
Technology,"  known as BART.  These sources would be required to implement  BART
within  five  years  after  the EPA  approved  state  plans  adopted  to  combat
visibility  impairment.  The  submission  of these plans is due between 2004 and
2008. In January 2001, the EPA proposed guidance to assist states in determining
which  sources  should be  subject  to the BART  requirement,  but the  proposed
guidance  has not  been  published  pending  a  review  by the  newly  appointed
administrator of the EPA. If the proposed rules are adopted, management believes
that the only existing  plant which may be required to comply with Clean Air Act
requirements  is our Neil  Simpson  I plant  and that any  capital  expenditures
associated  with  bringing the plant into  compliance  would not have a material
adverse effect on our financial condition or results of operations.

Title V of the Clean Air Act imposes federal requirements which dictate that all
of our fossil fuel-fired  generation  facilities must obtain operating  permits.
All of our existing facilities subject to this requirement have submitted timely
Title V permit applications and received permits.

On November 3, 1999, the United States  Department of Justice filed suit against
a number of electric  utilities  for alleged  violations  of the Clean Air Act's
"new source  review"  requirements  related to  modifications  of air  emissions
sources at electric  generating  stations located in the southern and midwestern
regions of the United  States.  Several  states have joined these  lawsuits.  In
addition,  the EPA has also issued administrative  notices of violation alleging
similar  violations  at  additional  power  plants  owned  by some  of the  same
utilities  named as defendants in the  Department of Justice  lawsuit,  and also
issued an  administrative  order to the Tennessee  Valley  Authority for similar
violations  at some of its power  plants.  The EPA has also issued  requests for
information  pursuant to the Clean Air Act to numerous other electric  utilities
seeking to determine whether those utilities also engaged in activities that may
have been in violation of the Clean Air Act's new source review requirements. To
date, we are aware of three large  utilities  that have either  settled with the
United States or have reached  agreements in principle to resolve these actions.
In each case,  the settling  party has agreed (or agreed in  principle) to incur
over $1 billion in expenditures  for the  installation  of additional  pollution
control,   the  retirement  or  repowering  of  coal-fired   generating   units,
supplemental  environmental  projects and civil  penalties.  No such proceedings
have been  initiated or requests for  information  issued with respect to any of
our  facilities,  but there can be no  assurance  that we will not be subject to
similar proceedings in the future.



In December 2000, the EPA announced its intention to regulate mercury  emissions
from  coal-fired  and oil-fired  electric  power plants under Section 112 of the
Clean  Air Act.  The EPA is  committed  to  proposing  a rule to  regulate  such
emissions by no later than 2003. Because we do not know what the EPA may require
with respect to this issue,  we are not able to evaluate the impact of potential
mercury  regulations on the operation of our  facilities.  Since the adoption of
the United Nations Framework on Climate Change in 1992, there has been worldwide
attention  with respect to  greenhouse  gas  emissions.  In December  1997,  the
Clinton administration participated in the Kyoto, Japan negotiations,  where the
basis of a climate change treaty was formulated.  Under the treaty, known as the
Kyoto  Protocol,  the United States would be required,  between 2008 and 2012 to
reduce its  greenhouse  gas  emissions by 7 percent  from 1990 levels.  However,
because  of  opposition  to the treaty in the United  States  Senate,  the Kyoto
Protocol  has not  been  submitted  to the  Senate  for  ratification.  Although
legislative  developments  on the state level related to controlling  greenhouse
gas emissions have occurred, we are not aware of any similar developments in the
states in which we operate.  If the United States ratifies the Kyoto Protocol or
we otherwise  become  subject to limitations on emissions of carbon dioxide from
our  plants,   these  requirements  could  have  a  significant  impact  on  our
operations.  In March 2001, the Bush administration  announced that it would not
seek to impose any limitations on carbon dioxide emissions.

Clean Water Act. Our existing  facilities are also subject to a variety of state
and  federal  regulations  governing  existing  and  potential  water/wastewater
discharges.  Generally,  such regulations are promulgated under authority of the
Clean Water Act and govern overall water/wastewater  discharges through National
Pollutant  Discharge  Elimination  System,  or  NPDES,  permits.  Under  current
provisions of the Clean Water Act,  existing NPDES permits must be renewed every
five years,  at which time permit  limits are  extensively  reviewed  and can be
modified  to account  for  changes in  regulations  or program  initiatives.  In
addition,  the  permits  have  re-opener  clauses  which  allow  the  permitting
authority (which may be the United States or an authorized  state) to attempt to
modify a permit to conform to changes in applicable laws and  regulations.  Some
of our existing  facilities  have been  operating  under NPDES  permits for many
years and have gone  through one or more NPDES  permit  renewal  cycles.  Two of
these  facilities  are currently in the process of renewing their existing NPDES
permits.

Solid Waste  Disposal.  We dispose of all solid wastes  collected as a result of
burning coal at our power plants in approved  solid waste disposal  sites.  Each
disposal site has been permitted by the state of its location in compliance with
law.  Ash and wastes from flue gas and sulfur  removal  from the Wyodak and Neil
Simpson II plants are deposited in mined areas. These disposal areas are located
below some shallow water aquifers in the mine. None of the solid wastes from the
burning of coal is classified as hazardous  material,  but the wastes do contain
minute traces of metals that would be perceived as polluting if such metals were
leached into underground water.  Recent  investigations  have concluded that the
wastes are relatively  insoluble and will not measurably  affect the post-mining
ground water quality. While management does not believe that any substances from
our solid waste disposal  activities will pollute  underground  water,  they can
give no assurances  that pollution  will not occur over time. In this event,  we
could experience material costs to mitigate any resulting damages. Agreements in
place  require  PacifiCorp  to be  responsible  for any such costs that would be
related to the solid waste from its 80 percent interest in the Wyodak plant.

Additional  unexpected  material  costs  could also  result in the future if the
federal or state government determines that solid waste from the burning of coal
contains some  hazardous  material that requires  special  treatment,  including
solid  waste of which we  previously  disposed.  In that event,  the  government
regulator  could  consequently  hold those  entities that disposed of such waste
responsible for such treatment.

Mine Reclamation.  Under federal and state laws and regulations, we are required
to  submit  to the  regulation  by,  and  receive  approval  from,  the  Wyoming
Department  of  Environmental  Quality (DEQ) for a mining and  reclamation  plan
which provides for orderly  mining,  reclamation  and  restoration of all of our
Wyodak  coal mine in  conformity  with  state laws and  regulations.  We have an
approved  mining permit and are otherwise in compliance  with other land quality
permitting programs.



Based on  extensive  reclamation  studies,  we  currently  estimate  the cost of
reclamation for our mine at approximately $26 million and have currently accrued
approximately $17.7 million on our balance sheet for these reclamation costs. No
assurance can be given that additional requirements in the future may be imposed
that would cause an  unexpected  material  increase in  reclamation  costs.  One
situation  that  could  result  in  substantial  unexpected  increases  in costs
relating to our  reclamation  permit  concerns three  depressions -- the "south"
depression, the "Peerless" depression and the "North Pit" depression - that have
or will result from our mining  activities  at the Wyodak  mine.  Because of the
thick coal seam and relatively shallow overburden,  the current restoration plan
would leave these depressions,  which have limited reclamation  potential,  with
interior drainage only.  Although the DEQ has accepted the current plan to limit
reclamation  of these  depressions,  it has  reserved  the right to  review  and
evaluate  future  reclamation  plans or to reevaluate  the existing  reclamation
plan. If as a result of our mining  activities,  additional  overburden  becomes
available,  the DEQ may  require us to  conduct  additional  reclamation  of the
depressions,  particularly if the DEQ finds that the current limited reclamation
is resulting in exceedances in the DEQ's water quality standards.

Ben French Oil Spill. In 1990 and 1991, we discovered extensive underground fuel
oil  contamination  at the Ben  French  plant  site.  With  the  help of  expert
consultants,  we worked closely with the South Dakota  Department of Environment
and Natural  Resources to assess and  remediate  the site.  Our  assessment  and
remediation  efforts  continue today and we continue to monitor the site. All of
our underground  oil-carrying  facilities from which the contamination  occurred
are now above ground. There have been no significant recoveries of free fuel oil
product since 1994.  Soil borings and monitoring  wells on the perimeters of our
Ben French plant  property  provide no  indication of  contamination  beyond the
property's  limits.  Management  believes  that the  underground  spill has been
sufficiently remedied so as to prevent any oil from migrating off site. However,
due to underground  gypsum deposits in this area, the fuel oil has the potential
of migrating to area  waterways.  In such event,  cleanup costs could be greatly
increased.  Management  believes that sufficient  remediation efforts to prevent
such a  migration  are  currently  in  place,  but due to the  uncertainties  of
underground geology, no assurance can be given.

Cleanup costs recognized to date total approximately  $472,000,  of which amount
$386,000 has been reimbursed by the South Dakota Petroleum Release  Compensation
Fund.  To date,  no  penalties,  claims or actions have been taken or threatened
against us because of this oil spill.

PCBs.  Under the  federal  Toxic  Substances  Control  Act,  the EPA has  issued
regulations that control the use and disposal of polychlorinated  biphenyls,  or
PCBs.  PCBs were  widely  used as  insulating  fluids in many  electric  utility
transformers and capacitors manufactured before the Toxic Substances Control Act
prohibited any further  manufacture  of PCB equipment.  We remove and dispose of
PCB-contaminated equipment in compliance with law as it is discovered.

Release of PCB-contaminated fluids, especially any involving a fire or a release
into a waterway,  could result in substantial cleanup costs.  Several years ago,
we began a testing program of potential  PCB-contaminated  transformers,  and in
1997 completed  testing of all transformers and capacitors which are not located
in our  electric  substations.  We have not  completed  the  testing  of  sealed
potential  transformers and bushings located in our electric  substations as the
testing   of   this   equipment   requires   their   destruction.   Release   of
PCB-contaminated  fluid,  if present,  from our  equipment  is unlikely  and the
volume of fluid in such equipment is generally  less than one gallon.  Moreover,
any release of this fluid would be confined to our substation site.

Exploration and Production

Our oil and gas  exploration  and  production  operations are subject to various
types of regulation at the federal, state and local levels. They include:

o    requiring permits for the drilling of wells;

o    maintaining bonding requirements in order to drill or operate wells;

o    submitting and implementing spill prevention plans;



o    submitting  notification  relating  to the  presence,  use and  release  of
     certain contaminants incidental to oil and gas operations;

o    regulating the location of wells,  the method of drilling and casing wells,
     the use, transportation,  storage and disposal of fluids and materials used
     in connection with drilling and production activities; and

o    regulating surface usage and the restoration of properties upon which wells
     have  been  drilled,   the  plugging  and   abandoning  of  wells  and  the
     transporting of production.

Our operations are also subject to various conservation  matters,  including the
regulation  of the size of drilling and spacing  units or proration  units,  the
number of wells which may be drilled in a unit and the unitization or pooling of
oil and gas properties.  In this regard, some states allow the forced pooling or
integration  of tracts to  facilitate  exploration  while  other  states rely on
voluntary  pooling  of lands and  leases,  which may make it more  difficult  to
develop oil and gas properties.  In addition,  state conservation laws establish
maximum  rates of  production  from oil and gas wells,  generally  prohibit  the
venting or flaring of gas and impose certain requirements  regarding the ratable
purchase of production.  The effect of these regulations is to limit the amounts
of oil and gas we can produce from our wells and to limit the number of wells or
the locations at which we can drill.  In addition,  various  federal,  state and
local laws and  regulations  concerning the discharge of  contaminants  into the
environment,   the   generation,   storage,   transportation   and  disposal  of
contaminants and the protection of public health,  natural  resources,  wildlife
and environment  affect our exploration,  development and production  operations
and our related costs.

Other Properties

In addition to the other  properties  described  herein,  we own an  eight-story
office building  consisting of approximately  47,000 square feet of office space
in Rapid City, South Dakota. We occupy  approximately 27,000 square feet in this
building and lease the remainder to others.

Employees

At  December  31,  2000,  we had 635  employees,  approximately  332 of whom are
employed in our utility  business,  170 of whom are employed in our  independent
energy businesses and 133 of whom are employed in our communications business.

Approximately  one-half  of our  utility  employees  are  covered by  collective
bargaining  agreements with the International  Brotherhood of Electrical Workers
which  expire  on  April 1,  2003.  We have  experienced  no  significant  labor
stoppages or labor disputes at our facilities.

ITEM 3.  LEGAL PROCEEDINGS

PacifiCorp Litigation

In August 2000, we initiated an action in the United States  District  Court for
the District of Wyoming against  PacifiCorp  relating to a coal supply agreement
between  PacifiCorp  and us.  We  believe  that  PacifiCorp  has  failed to make
complete  payment to us for coal sold under the coal supply  agreement  and that
PacifiCorp continues to underpay its monthly coal bill by approximately $100,000
per month. We believe that PacifiCorp's  actions constitute a breach of the coal
supply  agreement and have asked for relief in the amount of $5.0 million,  plus
all underpayments since the commencement of our lawsuit.



PacifiCorp  subsequently brought a counterclaim against us, alleging that we had
not properly  adjusted upward and downward the components which make up the coal
price under the coal  supply  agreement,  resulting  in alleged  overbilling  to
PacifiCorp  of  $35.0  million  to  $40.0  million  over  an  undefined  period.
PacifiCorp  further  alleged  that if past  practices  continue  our  adjustment
methodology  will  result in  additional  overcharges  of  approximately  $150.0
million  through  the balance of the term of the coal  supply  agreement,  which
expires  in June  2013.  In its  counterclaim,  PacifiCorp  seeks to cancel  and
terminate the contract and to recover monetary damages as proven at trial.

Management  believes that we have properly billed  PacifiCorp under the terms of
the  coal  supply  agreement  and  that  PacifiCorp's   withholding  of  payment
constitutes  a breach of contract on their part.  Although it is  impossible  to
predict  whether we will ultimately be successful with our claim or in defending
PacifiCorp's  claim or, if not successful,  what the impact might be, management
believes that the  disposition  of this matter will not have a material  adverse
effect on our  consolidated  results of  operations or financial  condition.  In
addition,  management  believes that the pending litigation has not affected and
will not affect our other agreements with PacifiCorp.

Other Litigation

There are no other  material  legal  proceedings  pending,  other than  ordinary
routine  litigation  incidental to our business,  to which we are a party. There
are no material legal  proceedings to which an officer or director is a party or
has a material interest adverse to us or our subsidiaries. There are no material
administrative or judicial  proceedings arising under  environmental  quality or
civil  rights  statutes  pending  or known to be  contemplated  by  governmental
agencies  to  which we are or would be a party  other  than the  SCAQMD  RECLAIM
requirements on the Ontario Facility "see ITEMS 1 AND 2. BUSINESS AND PROPERTIES

ITEM 7. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
     OF OPERATIONS

We  are  a  growth  oriented,   diversified  energy  holding  company  operating
principally in the United States. Our regulated and unregulated  businesses have
expanded  significantly in recent years.  Our independent  energy group produces
and  markets  power and fuel.  We produce  and sell  electricity  in a number of
markets,  with a strong  emphasis in the western United States.  We also produce
coal,  natural  gas and crude oil  primarily  in the Rocky  Mountain  region and
market  fuel  products  nationwide.  We also own Black  Hills  Power,  Inc.,  an
electric utility serving approximately 58,600 customers in South Dakota, Wyoming
and  Montana.  Our  communications  group  offers   state-of-the-art   broadband
communications  services to residential and business customers in Rapid City and
the northern Black Hills region of South Dakota.

                              Results of Operations

Consolidated Results

Consolidated net income for 2000 was $52.8 million, compared to $37.1 million in
1999 and  $25.8  million  in 1998 or $2.37  per  average  common  share in 2000,
compared  to $1.73  and  $1.19  per  average  common  share  in 1999  and  1998,
respectively.  This  equates to a 19.0  percent,  17.1  percent and 12.5 percent
return on year-end common equity in 2000, 1999 and 1998, respectively.

We  reported  record  earnings  in 2000,  primarily  due to strong  natural  gas
marketing  activity,  increased fuel  production,  expanded power generation and
increased  wholesale  off-system  electric utility sales.  Strong results in our
independent  energy  business  group in 2000 were  partially  offset by start-up
losses in our communications business. Unusual energy market conditions stemming
primarily from gas and  electricity  shortages in California  contributed to our
strong  financial  performance in 2000.  There was a $0.40  contribution to 2000
earnings per share due to prevailing prices of gas and electricity and unusually
wide gas trading margins that may not recur in the future.

Earnings  in 1999  increased  over  1998 due  primarily  to sales  growth in our
electric utility and improved results in our independent  energy business group,
partially offset by expected start-up losses in our communications business.

In 1998, we recorded an $8.8 million (after tax) charge to earnings related to a
write-down of certain oil and natural gas  properties.  Absent this charge,  our
earnings per average common share for 1998 would have been $1.60, and our return
on year-end  common  equity would have been 16.1  percent.  The  write-down  was
primarily due to historically low crude oil prices, lower natural gas prices and
a decline in value of certain unevaluated properties.

Consolidated  revenues were $1,623.8 million,  $791.9 million and $679.3 million
in 2000,  1999 and 1998,  respectively,  representing a 105 percent  increase in
2000 and a 17 percent increase in 1999.

The growth in revenues in 2000 was a result of high energy  commodity prices and
increased  volumes of fuel  marketed,  primarily  as a result of  extreme  price
volatility in the western  markets,  acquisitions  and growth in the independent
energy business group and increases in off-system sales by our electric utility.
Prices of natural gas  marketed  increased  from an average of  $1.97-$2.15  per
million  British  thermal  units in 1998 and 1999 to $4.19 per  million  British
thermal  units in 2000.  Daily  volumes of natural  gas  marketed  increased  35
percent from 635,500  million  British  thermal units per day in 1999 to 860,800
million British thermal units in 2000.

Revenue increases in 1999 resulted primarily from the acquisitions and growth in
the  fuel  marketing  segment  of our  independent  energy  business  group  and
off-system sales by our electric utility.



Revenue and net income (loss) provided by each business group as a percentage of
our total revenue and net income were as follows:

Net income from the  independent  energy  group is expected to exceed net income
derived  from our  utility in 2001.  We expect  that  earnings  growth  from the
independent energy group over the next few years will be driven primarily by our
continued expansion in the independent power production segment. We also believe
that continued  strength in commodity prices and energy markets will provide the
opportunity  for strong results in our fuel marketing and oil and gas production
operations.

Our  electric  utility has  continued  to produce  modest  growth in revenue and
earnings from the retail  business over the past two years. We believe that this
trend is stable and that, absent unplanned system outages,  it will continue for
the next  several  years due to the  extension of our  electric  utility's  rate
freeze until January 1, 2005. (See Rate  Regulation.) The share of the utility's
future earnings  generated from wholesale  off-system  sales will depend on many
factors,  including native load growth,  plant availability and commodity prices
in the western markets.

Although our communications  business  significantly  increased  residential and
business customers in 2000, we expect it will sustain  approximately $10 million
in  net  losses  in  2001,   with  annual  losses   decreasing   thereafter  and
profitability expected in the next three to four years.

The  following  business  group and segment  information  includes  intercompany
eliminations.

lower natural gas prices and a decline in the value of unevaluated properties.



EBITDA  represents  earnings before  interest,  income taxes,  depreciation  and
amortization  and  any  non-recurring  or  non-cash  items.  EBITDA  is  used by
management and some investors as an indicator of a company's  historical ability
to service debt.  Management believes that an increase in EBITDA is an indicator
of  improved  ability to service  existing  debt,  to sustain  potential  future
increases in debt and to satisfy capital  requirements.  However,  EBITDA is not
intended to represent cash flows for the period, nor has it been presented as an
alternative  to  either  operating  income,  or as  an  indicator  of  operating
performance or cash flows from operating, investing and financing activities, as
determined by generally accepted accounting principles.  EBITDA as presented may
not be comparable to other similarly titled measures of other companies.

* Since the acquisition date

The independent  energy business group's revenues  increased 119 percent in 2000
and 20 percent in 1999. The revenue  increase in 2000 was a direct result of gas
and  electricity  shortages  in the West Coast  markets  and the  closing of the
Indeck  Capital  acquisition.  The revenue  increase in 1999 was  primarily  the
result of consolidating our three fuel marketing companies'  operations from the
time of their acquisitions.  Additionally, revenues increased in both years as a
result of increased  volumes and increased fuel and power prices.  Daily volumes
of natural gas marketed increased 35 percent in 2000 and 21 percent in 1999. The
July 2000  acquisition  of Indeck  Capital  contributed  to our strong  earnings
growth in 2000. In addition, in December 2000, we sold our ownership interest in
a power fund management company which resulted in a $3.7 million pre-tax gain.

The independent  energy business  group's total operating  expenses,  EBITDA and
operating  income  increased  over 115  percent,  160 percent  and 329  percent,
respectively,  in 2000 compared to 1999. Net income of this group  increased 144
percent in 2000.  These  increases  resulted  primarily  from our gas  marketing
operations,  which  experienced a dramatic  increase in both trading volumes and
margins,  a significant  increase in fuel  production  volumes,  record fuel and
power prices and expanded power  generation.  The  independent  energy  business
group's 1999 net income  improved over 1998  (excluding  the non-cash  charge in
1998)  primarily  due to record  gas  production,  improved  oil  prices,  lower
depletion  expense and the sale of certain  retail gas  marketing  operations in
1999,  partially offset by a non-cash  write-down of certain  intangible  assets
relating to our wholesale gas marketing office in Houston.




Coal Mining

Coal mining results were as follows:

A planned  five-week  overhaul of the Wyodak plant  resulted in lower coal sales

*Excludes  the  impact of a $13.5  million  pre-tax,  $8.8  million  after  tax,
  non-cash write-down relating to oil and gas properties due to historically low
  crude oil  prices,  lower  natural  gas  prices  and a decline in the value of
  unevaluated properties.

Record net income in 2000 was  primarily a result of record  natural gas prices,
higher  crude oil prices,  and a  significant  increase in  production  volumes.
Operating  results for 1998 decreased  primarily as a result of historically low
crude oil prices,  which not only reduced  revenue but also increased  depletion
expense (lower oil and gas prices reduce the  economically  recoverable  reserve
amounts,  causing an increase in depletion expense). We recognized approximately
$3.7 million,  $2.6 million and $4.9 million of depletion expense (excluding the
write-down  in 1998) related to gas and oil  production in 2000,  1999 and 1998,
respectively.

The following is a summary of our oil and gas reserves at December 31:


                                                          2000                   1999                  1998

These reserves are based on reports prepared by Ralph E. Davis Associates, Inc.,
an independent  consulting and engineering firm.  Reserves were determined using
constant  product  prices  at the  end of the  respective  years.  Estimates  of
economically  recoverable reserves and future net revenues are based on a number
of variables, which may differ from actual results. The increase in oil reserves
at  December  31,  2000 was due to  improved  product  prices.  The  increase in
reserves  at  December  31,  1999 was due to strong  drilling  results,  reserve
acquisitions and improved  product prices.  We intend to increase our net proved
reserves by selectively  increasing our oil and gas  exploration and development
activities and by acquiring producing properties.



Fuel Marketing

Our fuel marketing companies produced the following results:


                                                          2000                   1999                  1998

        Operating income (loss)                             23,800                (2,200)                     -
        Net income                                          14,000                  (200)                  (300)
        EBITDA                                              23,700                 2,500                    600


Record volumes  marketed and strong  margins  contributed to the increase in net
income from fuel  marketing in 2000 compared to 1999 and 1998.  During 1999, the
fuel marketing companies sold certain of their retail gas marketing  operations,
resulting in after-tax gains of approximately $1.8 million. In 1999, revenue and
the  related  cost  of  sales  increased  primarily  due to a full  year of coal
marketing operations (acquired in September 1998),  increased product prices and
increased  oil  volumes  marketed.  Operating  income in 1999 was  reduced  by a
non-cash  write-down of certain  intangible assets relating to the wholesale gas
marketing office in Houston in the amount of  approximately  $1.2 million (after
tax).

Our fuel marketing companies generate large amounts of revenue and corresponding
expense  related to buying and selling  energy  commodities.  Fuel  marketing is
extremely competitive,  and margins are typically very small. The unusual energy
market conditions stemming primarily from natural gas and electricity  shortages
in California  contributed to the strong  financial  performance in 2000 and may
not recur in the future.  However,  we believe that the continued  growth of our
fuel  and  power  production  businesses  will  create  opportunities  for us to
continue to generate strong fuel marketing operating results in future years.

Independent Power Production

Our independent power segment produced the following results:


                                                          2000                  1999                   1998

Results from the  independent  power  production  segment  were not  significant
either in 1999 or 1998.  In July 2000, we completed  the  acquisition  of Indeck
Capital,   representing  a  significant  advancement  of  our  position  in  the
independent power production  segment. We now own 250 net megawatts in currently
operating  plants.  Of this 250 net  megawatts,  approximately  179 megawatts is
under  contracts  or  tolling  arrangements  with at least  one year  remaining;
approximately  40 megawatts is owned through  minority  interests in independent
power investment  funds which we do not manage,  and the remainder is sold under
short-term  market  arrangements.  An  additional  470  megawatts of  generating
capacity is currently under construction. We expect to sell substantially all of
this  output  under  long-term  contracts.  We expect to increase  revenues  and
earnings in this segment beyond 2001 through future project development.

Electric revenue increased 30.1 percent in 2000 compared to 3.1 percent in 1999.
The  increase  in  electric  revenue in 2000 was  primarily  due to a 54 percent
increase in wholesale  off-system  sales at an average  price that was 3.1 times
higher than the average  price in 1999.  The  increase in  off-system  sales was
driven by high spot  market  prices  for  energy in 2000,  which  enabled  us to
generate more energy from our combustion turbine facilities,  including the Neil
Simpson  combustion  turbine which we placed into  commercial  operation in June
2000.  Megawatthours  generated from our oil-fired diesel and natural  gas-fired
combustion  turbines  were  305,767 in 2000,  25,882 in 1999 and 33,082 in 1998.
Historically,  market  prices were not  sufficient  to support the  economics of
generating from these facilities,  except to meet peak demand and as standby use
for native load requirements.

Firm kilowatthour  sales increased 2.8 percent in 2000 compared to a decrease of
0.1 percent in 1999. Residential and commercial sales increases of 6 percent and
3 percent,  respectively,  in 2000 were partially offset by a 2 percent decrease
in industrial  sales,  primarily due to load  reductions at Homestake Gold Mine.
Degree  days,  a measure of  weather  trends,  were 16 percent  above 1999 and 1
percent above normal in 2000.  Degree days in 1999 were 9 percent below 1998 and
13 percent below normal.  The increase in electric revenue in 1999 was primarily
due to stable  firm sales  combined  with a 20 percent  increase  in  off-system
sales.

Revenue  per  kilowatthour  sold was 6.4 cents in 2000  compared to 5.4 cents in
1999 and 1998.  The number of customers in the service area  increased to 58,601
from 57,709 in 1999 and from 56,856 in 1998. The revenue per  kilowatthour  sold
in 2000 reflects a 54 percent  increase in wholesale  non-firm  sales to 684,378
megawatthours  and robust  wholesale power prices.  The revenue per kilowatthour
sold in 1999  reflects the 20 percent  increase in wholesale  non-firm  sales to
445,712 megawatthours. The revenue per kilowatthour sold in 1998 reflects the 33
percent increase in wholesale non-firm sales to 371,104 megawatthours.

Electric utility  operating  expenses  increased by 30 percent in 2000 primarily
due to increased fuel, purchased power, and operating and maintenance  expenses,
partially offset by lower  depreciation.  Fuel expense in 2000 included the cost
associated with the additional combustion turbine generation. Operating expenses
increased  2.0  percent  in 1999,  primarily  due to  increased  purchase  power
expense, operations and maintenance expenses and depreciation,  partially offset
by lower fuel expense.

We forecast firm energy sales in our retail  service  territory to increase over
the next 10 years at an annual compound growth rate of  approximately 1 percent,
with the  system  demand  forecasted  to  increase  at a rate of 2  percent.  We
currently have a winter peak of 344 megawatts established in December 1998 and a
summer peak of 372 megawatts  established  in August 2000.  These  forecasts are
derived  from  studies  conducted  by us whereby we examined  and  analyzed  our
service  territory to estimate  changes in the needs for  electrical  energy and
demand over a 20-year period. These forecasts are only estimates, and the actual
changes in electric sales may be substantially different. Weather deviations can
also affect  energy sales  significantly  when  compared to  forecasts  based on
normal weather.

In  September   1998,   we  formed  our   communications   business  to  provide
facilities-based  communications  services for Rapid City and the northern Black
Hills  of  South   Dakota.   We  have   invested   more  than  $100  million  in
state-of-the-art  technology  that  offers  local  and long  distance  telephone
service, expanded cable television service, Internet access, and high-speed data
and video services.  The build-out is  approximately  75 percent complete and is
expected to be completed in 2001. Further capital  expenditures of approximately
$31.3  million are expected over the next two years to complete the build-out of
the fiber optic network and to acquire  customer  premise  equipment for sale to
customers.

We began serving  communications  customers in late 1999 and market our services
to schools,  hospitals,  cities,  economic  development groups, and business and
residential  customers.  Operating losses in 2000 were attributable to increased
interest,  depreciation  and operating  expenses.  Operating losses in 1999 were
primarily due to start-up  organizational costs,  increased depreciation expense
and increased  interest expense  associated with the capital  deployment.  As of
December  31,  2000,  we  had  8,368  residential  customers  and  646  business
customers.  We expect to more than double the number of customers  in 2001.  Our
goal is to attain 50 percent residential penetration while serving 35 percent of
all broadband business customers within our service territory.  If we are unable
to attract  additional  customers  or  technological  advances  make our network
obsolete, we could have a write-down of our assets which could be material.

                         Liquidity and Capital Resources

In 2000, we generated sufficient cash flow from operations to meet our operating
needs, to pay dividends on common stock and to pay long-term debt maturities. We
funded  property  additions  primarily  related to  construction  of  additional
electric generation facilities for our independent energy business group through
a combination of operating cash flow,  increased  short-term  debt and long-term
non-recourse  project financing.  Investing and financing  activities  increased
primarily  as a result of the  acquisition  of Indeck  Capital  in July 2000 and
construction  of several  generating  facilities.  Cash  flows  from  operations
increased $0.7 million,  primarily due to increased net income and  depreciation
partially  offset by increased  working capital.  We expect increased  operating
cash flows  resulting  from our investing  activities to support the  additional
indebtedness.

As part of our  acquisition  of Indeck  Capital,  we incurred  $40.3  million of
additional  debt  through an increase in  borrowings  on our  short-term  credit
facilities,  which were used to repay certain  obligations of Indeck Capital. In
addition,  we issued  1.537  million  shares of common stock and 4,000 shares of
convertible preferred stock to the former Indeck Capital shareholders.

In 1999,  we generated  cash from  operations  sufficient  to meet our operating
needs,  to pay dividends on our common stock,  to pay long-term debt  maturities
and to  provide  financing  for our  investment  in  independent  power  assets.
Property additions were primarily financed through increased short-term debt and
notes payable. Cash flows from operations increased $19 million primarily due to
increased net income and decreased  working  capital.  Cash flows from investing
activities increased  substantially,  primarily related to the deployment of our
fiber optic  communications  network and our investment in the  construction  of
generating facilities.  Cash flows from financing activities increased primarily
due to increased short-term indebtedness to fund our investing activities.



In the past, we have relied upon internally  generated funds and the issuance of
short-  and  long-term  debt  to  finance  our  activities.  We  expect  that an
appropriate mix of financing options will be used to finance future activities.

Dividends  paid on our  common  stock  totaled  $1.08  per  share in 2000.  This
reflected  increases  approved by our board of directors from $1.04 per share in
1999 and  $1.00  per  share in 1998.  All  dividends  were  paid out of  current
earnings.  Our three-year  annual  dividend  growth rate was 4.4 percent and our
payout ratio for 2000 was 45 percent.  In January  2001,  our board of directors
increased  the  quarterly  dividend  3.7 percent to 28 cents per share.  If this
dividend is maintained during 2001, it will be equivalent to $1.12 per share, an
annual increase of 4 cents per share. The  determination of the amount of future
cash  dividends,  if any, to be declared and paid will depend upon,  among other
things, our financial condition, funds from operations, the level of our capital
expenditures,  restrictions  under our credit facilities and our future business
prospects.

Our capital  additions for 2000 were $215  million.  The major capital items for
the year  included  the  following:  acquisition  of the net  assets  of  Indeck
Capital;  completion of  construction  of the 80 megawatt  gas-fired  generation
units at the Arapahoe  site in Denver,  Colorado,  which we placed in service in
May 2000;  completion  of  construction  of the 40  megawatt  gas-fired  Valmont
combustion turbine unit located in Boulder, Colorado, which we placed in service
in May 2000;  acquisitions  of various  interests  in  partnerships  in which we
previously  held a  minority  interest;  completion  of  construction  of the 40
megawatt  gas-fired  Neil  Simpson  combustion  turbine unit at our Wyodak site,
which  we  placed  in  service  in  June  2000;  and  the  construction  of  our
communications fiber optic network.

Forecasted  capital   requirements  for  projected  plant  construction,   other
independent  energy  investments,  regulated  utility capital  improvements  and
completion of the communications network are as follows:

Our independent energy business group's forecasted capital  requirements include
the following:

o    Acquisition of a 240 megawatt Fountain Valley gas-fired turbine  generation
     facility  currently  under  construction,  located near  Colorado  Springs,
     Colorado.  Construction  is  expected  to be  completed  in  2001,  with an
     expected cost of approximately $175 million.


o    Completion of construction of a 40 megawatt gas-fired combustion turbine at
     our Wyodak, Wyoming site (expected in mid-2001).

o    Completion of  construction of a 40 megawatt  gas-turbine  expansion at our
     Valmont, Colorado site (expected in mid-2001).

o    Completion of construction of a 50 megawatt combined-cycle expansion at our
     Arapahoe, Colorado site (expected in mid-2002).

o    Expansion of the Harbor Cogeneration plant in Wilmington, California with a
     30  megawatt   combined-cycle  upgrade.  This  expansion  is  currently  in
     development,  with anticipated completion in the second quarter of 2001. We
     have a 31.8 percent financial interest in this project.

o    Acquisition  of  operating  and  non-operating  interests in 74 gas and oil
     wells from Stewart Petroleum Corporation, which is expected to be completed
     in April 2001.

o    Construction of a 40 megawatt  gas-fired turbine known as the Lange project
     (expected in mid-2002).

o    Expected  development of an additional 400 megawatts of generating capacity
     in years 2002-2003.

We expect to finance  our  independent  energy  business  group's  purchase  and
construction  of  electric  generating  facilities,  primarily  with  long-term,
non-recourse  project  level debt.  We expect that any  project-level  debt will
contain  significant  restrictions on  distributions of cash from the project to
us.

In  addition  to the above  forecasted  capital  items we will lease the Wygen I
plant, a 90 megawatt coal-fired plant under construction at our Wyodak,  Wyoming
site.  Because of the leasing  arrangement,  the $130 million total construction
costs of the plant are not included in the above three-year capital  expenditure
forecast.  Wygen I will be  similar in design to our Neil  Simpson II  facility,
which was  completed in 1995 at the same site.  The plant will run on low-sulfur
coal fed by conveyor from our adjacent  Wyodak coal mine and will use the latest
available environmental control technology. We anticipate that the Wygen I plant
will be operational by March of 2003.

Forecasted capital  expenditures for our electric utility operations include new
transmission and substation projects, re-build projects on existing transmission
lines,  distribution  projects in response to  customer  requests  for  electric
service,  capital  projects  associated with our utility's  existing  generation
plants, and other  miscellaneous  items. We do not expect additional  generation
capacity to be added to our utility over the forecast period.

Our communications  group's capital requirements  forecast primarily consists of
2001 costs  related to the  completion  of our fiber optic network in Rapid City
and the  northern  Black Hills of South  Dakota.  We expect  construction  to be
substantially  completed by November 2001, with forecasted capital  expenditures
thereafter  consisting  of capital  improvements  to the then  existing  network
infrastructure.

Lines of Credit

We have lines of credit with various banks totaling $290 million at December 31,
2000 and $115  million at December 31, 1999,  which are  currently  available to
support  bank  borrowings  or to provide for letters of credit.  There were $211
million of borrowings  and $20.6 million of letters of credit issued under these
lines of credit at December 31, 2000,  and $96.6  million of  borrowings  and no
letters of credit  issued at December 31, 1999. We had no  compensating  balance
requirements  associated  with these  lines of  credit.  The lines of credit are
subject to periodic review and renewal during the year by the banks.



In addition,  Enserco  Energy,  Inc., our gas marketing  unit, has a $90 million
uncommitted, discretionary line of credit to provide support for the purchase of
natural  gas. We provide no  guarantee  to the lender  under this  facility.  At
December  31, 2000 and 1999,  there were  outstanding  letters of credit  issued
under the facility of $69.8  million and $19.9  million,  respectively,  with no
borrowing balances on the facility.

Similarly, Black Hills Energy Resources, Inc., our oil marketing unit, has a $25
million uncommitted, discretionary credit facility. This line of credit provides
credit  support for the purchases of crude oil by Black Hills Energy  Resources.
We provide no guarantee to the lender under this facility.  At December 31, 2000
and 1999, Black Hills Energy Resources had letters of credit outstanding of $8.5
million  and $13.2  million,  respectively,  and no balance  outstanding  on its
overdraft line.

Coal Reclamation Reserves

Under our mining permit, we are required to reclaim all land where we have mined
coal reserves.  The cost of reclaiming the land is accrued as the coal is mined.
While the  reclamation  process  takes place on a continual  basis,  much of the
reclamation occurs over an extended period after we mine the area. Approximately
$0.7 million is charged to operations as  reclamation  expense  annually.  As of
December 31, 2000, accrued reclamation costs were approximately $17.7 million.

Long-term Debt/Credit Ratings

The long-term debt  component of our capital  structure at December 31, 2000 and
1999 was 52 percent and 43 percent,  respectively.  With expected  growth within
the  independent  energy  business group, we anticipate our long-term debt ratio
will increase to 55-60 percent in the next five years.

Our utility's first mortgage bonds are rated "A1" by Moody's Investors  Service,
Inc. and "A+" by Standard & Poor's Ratings  Services.  These ratings reflect the
respective  agencies'  opinions  of the credit  quality of our  utility  and the
security underlying the first mortgage bonds.

                             Market Risk Disclosures

Price Risk Management

Our  operations  are exposed to market risk  arising  from  changes in commodity
prices.  These changes could cause  fluctuations in our earnings and cash flows.
In the normal  course of  business,  we  actively  manage our  exposure to these
market risks by entering into various hedging transactions. Hedging transactions
involve  the use of a variety  of  derivative  financial  instruments.  Our risk
management policies place clear controls on these activities.

We have adopted risk management  policies and procedures,  approved by our board
of  directors,  and reviewed  routinely  by the audit  committee of the board of
directors.  Our risk  management  policies and procedures  include,  but are not
limited to, risk tolerance  levels relating to authorized  derivative  financial
instruments, position limits, authorization of transactions and credit exposure.

Operating margins earned by wholesale gas and crude oil marketing are relatively
insensitive to commodity price fluctuations since most of the purchase and sales
contracts do not contain fixed-price provisions.  Generally, prices contained in
these contracts are tied to a current spot or index price and, therefore, adjust
directionally with changes in



overall  market  conditions.  We  generally  attempt to balance our  fixed-price
physical and financial purchase and sales commitments.  However, we may at times
have a bias in the market,  within  established  guidelines,  resulting from the
management  of  our  portfolio.  To  the  extent  a net  open  position  exists,
fluctuating commodity market prices can impact our financial position or results
of  operations,  either  favorably or  unfavorably.  The net open  positions are
actively managed,  and the impact of changing prices on our financial  condition
at a  point  in  time is not  necessarily  indicative  of the  impact  of  price
movements throughout the year.

Effective  January 1, 1999, we adopted the  provisions  of Emerging  Issues Task
Force  Issue No.  98-10,  "Accounting  for Energy  Trading  and Risk  Management
Activities" (EITF 98-10).  The resulting effect of adoption of the provisions of
EITF  98-10  was  to  alter  our   comprehensive   method  of   accounting   for
energy-related contracts, as defined in that statement.

We account  for all energy  trading  activities  at fair value as of the balance
sheet date and recognize  currently the net gains or losses  resulting  from the
revaluation of these contracts to fair value in our results of operations.  As a
result, substantially all of the energy trading activities of our gas marketing,
crude oil marketing and coal  marketing  operations are accounted for under fair
value accounting methodology as prescribed in EITF 98-10.

Through our independent energy business group, we utilize financial  instruments
for  our  fuel  marketing   services.   These  financial   instruments   include
fixed-for-float swap financial  instruments,  basis swap financial  instruments,
and costless collars traded in the over-the-counter financial markets.

The derivatives are not held for speculative  purposes but rather serve to hedge
our exposure  related to commodity  purchases or sales  commitments.  Under EITF
98-10,  these  transactions  qualify as energy trading  activities  that must be
accounted for at fair value. As such,  realized and unrealized  gains and losses
are recorded as a component of income.  Because we do not speculate  with "open"
positions,   substantially  all  of  our  trading  activities  are  back-to-back
positions  where a  commitment  to  buy/(sell)  a  commodity  is matched  with a
committed sale/(buy) or financial  instrument.  The quantities and maximum terms
of derivative  financial  instruments  held for trading purposes at December 31,
2000 and 1999 are as follows:

There were no  significant  differences  between the fair  values of  derivative
assets and liabilities at December 31, 1999.

Non-trading Energy Activities

To reduce risk from  fluctuations  in the price of oil and natural gas, we enter
into swaps and costless collar transactions.  We use these transactions to hedge
price risk from sales of our  forecasted  crude oil and natural gas  production.
For such transactions, we utilize hedge accounting.

At December 31, 2000, we had fixed-for-float swaps for 17,000 barrels of oil per
month for the year 2001 to hedge our crude oil price  risk with a fair  value of
$34,000.  We had  fixed-for-float  swaps for 10,000 barrels of oil per month for
the year 2002 to hedge our crude oil price risk with a fair  value of  $416,000.
We also had costless collars  (purchased  puts-sold calls) for 10,000 barrels of
oil per month for 2001 with a fair value of $323,000.  We hedged our  forecasted
2001 natural gas production with  fixed-for-float  swaps. We had fixed-for-float
swaps for 1,581,000  million  British  thermal units with a fair value of $(3.4)
million.  These amounts are not reflected in our December 31, 2000  consolidated
balance  sheet,  but will be recorded as part of the  adoption of  Statement  of
Financial  Accounting  Standards  (SFAS) No.  133,  "Accounting  for  Derivative
Instruments and Hedging Activities," on January 1, 2001.

Financing Activities

To reduce risk from  fluctuations in interest rates, we enter into interest rate
swap  transactions.  We use these  transactions  to hedge interest rate risk for
variable  rate  debt  financing.   For  such  transactions,   we  utilize  hedge
accounting.  At December  31, 2000,  we had interest  rate swaps with a notional
amount  of $127.4  million,  which  have a maximum  term of six years and a fair
value of $(7.5)  million.  These  amounts are not  reflected in our December 31,
2000 consolidated balance sheet, but will be recorded as part of the adoption of
SFAS No. 133 on January 1, 2001.

Credit Risk

In addition to the risk  associated  with price  movements,  credit risk is also
inherent in our risk management  activities.  Credit risk relates to the risk of
loss  resulting   from   non-performance   of   contractual   obligations  by  a
counterparty. While we have not experienced significant losses due to the credit
risk associated with these  arrangements,  we have off-balance sheet risk to the
extent that the counterparties to these transactions fail to perform as required
by the terms of their contracts.



Interest Rate Risk

Our exposure to market risk for changes in interest  rates relates  primarily to
our  short-term  investments  and long-term debt  obligations.  As stated in our
policy,  we are averse to principal loss and ensure the safety and  preservation
of our investments by limiting default risk, market risk and reinvestment risk.

We mitigate  default risk on short-term  investments by investing in high credit
quality securities  consisting primarily of tax-exempt federal,  state and local
agency  obligations,  by  periodically  monitoring  the  credit  rating  of  any
investment issuer or guarantor and by limiting the amount of exposure to any one
issuer.  Our portfolio  includes only securities with active secondary or resale
markets to ensure portfolio  liquidity.  All short-term  investments  mature, by
policy,  in two  years or less.  The  effect of a 100  basis  point (1  percent)
increase  in interest  rates would not have a material  effect to our results of
operations  or  financial  condition,  due to  the  short-term  duration  of the
investment portfolio.

At December 31, 2000, we had $162.2 million of outstanding floating rate debt of
which $34.8  million was not offset with interest  rate swap  transactions  that
effectively convert the interest on that debt to a fixed rate.




The table below presents  principal (or notional)  amounts and related  weighted
average  interest rates by year of maturity for our short-term  investments  and
long-term debt obligations, including current maturities (in thousands).

                                Rate Regulation

Existing Rate Regulation

In  June  1999,  the  South  Dakota  Public  Utilities   Commission  approved  a
settlement,  which  extended a rate freeze in effect since 1995 until January 1,
2005.



The South Dakota settlement provides that, absent an extraordinary event, we may
not file for any  increase in our rates or invoke any fuel and  purchased  power
adjustment  tariff  which  would  take  effect  during the  freeze  period.  The
specified extraordinary events are:

o    new  governmental  impositions  increasing  annual  costs for South  Dakota
     customers by more than $2.0 million;

o    simultaneous  forced  outages of both our Wyodak  plant and Neil Simpson II
     plant projected to continue at least 60 days;

o    forced  outages  occurring to either  plant which  continue for a period of
     three months and is  projected to last at least nine months;

o    an increase in the  Consumer  Price Index at a monthly  rate for six months
     which would result in a 10 percent or higher annual inflation rate;

o    the loss of a South  Dakota  customer  or revenue  from an  existing  South
     Dakota  customer  that would result in a loss of revenue of $2.0 million or
     more during any 12-month period;

o    the cost of coal to our South Dakota  customers  increases and is projected
     to  increase  by more than $2.0  million  over the cost for the most recent
     calendar year; and

o    electric  deregulation  occurs  as a  result  of  either  federal  or state
     mandate,  which  allows  any of our  customers  to choose its  provider  of
     electricity at any time during the freeze period.

During the freeze period,  except as identified  above,  we are  undertaking the
risks of:

o    machinery  failure;

o    load loss caused by either an economic downturn or changes in regulation;

o    increased  costs  under  power  purchase  contracts  over  which we have no
     control;

o    government interferences; and

o    acts of nature and other unexpected events that could cause material losses
     of income or increases in costs of doing business.

However, the settlement  anticipates that we will retain,  during that period of
time, earnings realized from more efficient operations,  sales from load growth,
and off-system sales of power and energy.

Over  the last  three  years  we have  initiated  an  effort  to enter  into new
contracts with our largest industrial customers. The new contracts contain "meet
or release"  provisions  which grant us a five-year right to continue to serve a
customer at market rates in the event of deregulation. Additionally, through our
new General Service Large Optional  Combined  Account  Billing  Tariff,  we have
allowed  general service  customers to aggregate  their loads.  This tariff also
provides us with a five-year  right to continue to serve those  customers in the
event of deregulation. Our "meet or release" contracts currently total more than
116 megawatts of large commercial and industrial  load. These contracts  provide
us the  assurance of a firm local market for our power  resources,  in the event
deregulation occurs. These industrial and large commercial  customers,  together
with our wholesale power sale agreements with the City of Gillette,  Wyoming and
Montana-Dakota   Utilities  Company,  equal  approximately  48  percent  of  our
utility's firm load.

Regulatory Accounting

We  follow  SFAS  No.  71,  "Accounting  for the  Effects  of  Certain  Types of
Regulation," and our financial  statements  reflect the effects of the different
ratemaking principles followed by the various jurisdictions in which we operate.
As a result of our regulatory  activity, a 50-year depreciable life for the Neil
Simpson  II plant  is used  for  financial  reporting  purposes.  If we were not
following  SFAS 71, a 35- to 40-year  life would  probably  be more  appropriate
which would  increase  depreciation  expense by  approximately  $0.6 million per
year.  If  rate  recovery  of  generation-related   costs  becomes  unlikely  or
uncertain,  due to competition or regulatory action,  these accounting standards
may no longer apply





to our generation  operations.  In the event we determine that we no longer meet
the  criteria for  following  SFAS 71, the  accounting  impact to us would be an
extraordinary non-cash charge to operations of an amount that could be material.
Criteria that may give rise to the  discontinuance of SFAS 71 include increasing
competition  that could  restrict  our  ability to  establish  prices to recover
specific costs and a significant  change in the manner in which rates are set by
regulators  from  cost-based  regulation  to  another  form  of  regulation.  We
periodically review these criteria to ensure that the continuing  application of
SFAS 71 is appropriate.


                           Business Outlook Statements

Business Strategy

Our  strategy  is  to  build  long-term   shareholder  value  by  deploying  our
development,  operating and marketing expertise in the energy industry.  We plan
to  operate  a mix of  unregulated  independent  energy  and  regulated  utility
businesses,  with emphasis on independent  power  generation and fuel production
segments.

Our strategy includes the following key elements:

o    grow our  independent  power  segment by  developing  and  acquiring  power
     projects primarily in the western United States;

o    expand the  generating  capacity of our existing  sites  through a strategy
     known as "brownfield development;"

o    sell a large  percentage  of the  production  from  our  independent  power
     projects  through  long-term   contracts  in  order  to  secure  attractive
     investment returns;

o    increase our reserves of natural gas and expand our coal production;

o    exploit our fuel cost advantages and our operating and marketing  expertise
     to remain a low-cost power producer;

o    exploit our knowledge and market expertise while managing the risk inherent
     in fuel marketing;

o    build and maintain strong  relationships  with wholesale energy  customers;
     and

o    capitalize on our utility's established market presence,  relationships and
     customer loyalty.

Future Communications Activities

Our communications operations are expected to have operating losses for the next
three to four years. The recovery of capital investment and future profitability
are  dependent  primarily  on our  ability to attract new  customers,  including
customers from incumbent providers such as Qwest Communications and Midcontinent
Communications, the incumbent telephone and cable television providers. Although
we do not  anticipate  being  regulated  in the local  markets  we are unable to
predict  future  markets,  future  government  impositions  and future  economic
conditions  that  could  affect  the  profitability  of the  communications  and
technology operations.



Recent Developments and Acquisitions

In March  2001,  we signed a  definitive  agreement  to  acquire a 240  megawatt
gas-fired turbine  generation  facility located near Colorado Springs,  Colorado
from Enron  Corporation.  The  transaction is expected to close around March 31,
2001.

The  Fountain  Valley  facility  features  six LM-6000  simple-cycle,  gas-fired
turbines,  a technology  identical to our  existing  facilities  in Colorado and
Wyoming. All necessary permitting has been approved and the plant is expected to
phase in its generation  capacity beginning in June 2001. We also announced that
we obtained an 11-year  contract with Public  Service of Colorado to utilize the
plant for peaking  purposes.  The contract is a tolling  arrangement in which we
assume no fuel costs.  The cost of the  project is expected to be  approximately
$175  million.  We expect to finance the  project  primarily  with  non-recourse
project  level debt,  and  negotiations  are  presently  under way with  certain
lenders.

Risks and Uncertainties

In  connection  with  the  safe  harbor  provisions  of the  Private  Securities
Litigation  Reform Act of 1995 (Reform  Act),  we are hereby  filing  cautionary
statements  identifying important factors that could cause our actual results to
differ  materially from those projected in  forward-looking  statements (as such
term is defined in the  Reform  Act) made by or on behalf of the  Company in our
Annual Report on Form 10-K,  Annual Report,  Quarterly  Report on Form 10-Q, and
presentations,  or in response  to  questions  or  otherwise.  These  statements
concern  our plans,  expectations  and  objectives  for future  operations.  All
statements,  other than statements of historical fact, that address  activities,
events or developments  that we expect,  believe or anticipate will or may occur
in the future are forward-looking statements. The words "anticipate," "believe,"
"estimate,"  "expect,"  "intend,"  "plan,"  "predicts,"  "project," "will likely
result,"  "will  continue,"  or  similar   expressions  are  not  statements  of
historical fact and may be  forward-looking.  These  forward-looking  statements
include, among others, such things as:

o    expansion and growth of our business and operations
o    future financial performance;
o    future acquisition and development of power plants;
o    future production of coal, oil and natural gas;
o    reserve estimates; and
o    business strategy.

Forward-looking  statements  are  based  on  assumptions  which we  believe  are
reasonable based on current expectations and projections about future events and
industry conditions and trends affecting our business.  However,  whether actual
results and  developments  will conform to our  expectations  and predictions is
subject to a number of risks and uncertainties  which could cause actual results
to differ  materially  from those contained in the  forward-looking  statements,
including the following factors:

o    prevailing  governmental  policies and regulatory actions,  with respect to
     allowed  rates of return,  industry  and rate  structure,  acquisition  and
     disposal of assets and  facilities,  operation  and  construction  of plant
     facilities,  recovery of purchased power and other capital investments, and
     present or prospective wholesale and resale competition;

o    changes in and compliance with environmental and safety laws and policies;

o    weather conditions;

o    population growth and demographic patterns;



o    competition for retail and wholesale customers;

o    pricing and transportation of commodities;

o    market demand, including structural market changes;

o    changes in tax rates or policies or in rates of inflation;

o    changes in project costs;

o    unanticipated changes in operating expenses or capital expenditures;

o    capital market conditions;

o    credit-worthiness of counterparties;

o    technological advances;

o    competition for new energy development opportunities; and

o    legal and  administrative  proceedings  that  influence  our  business  and
     profitability.

Any forward-looking statement speaks only as to the date on which that statement
is made, and we undertake no obligation to update any forward-looking  statement
to reflect  events or  circumstances  after the date on which that  statement is
made or to reflect the  occurrence of an anticipated  event.  New factors emerge
from time to time,  and it is not  possible for  management  to predict all such
factors,  nor can it assess the impact of any such factor on the business or the
extent to which factor,  or combination of factors,  may cause results to differ
materially from those contained in any forward-looking statement.
