RESULTS  OF  OPERATIONS

The  Company had net income of $8.9 million for 2002, a net loss of $6.4 million
for 2001 and net income of $16.7 million for 2000.  The results for 2001 include
several  unusual  items,  including  losses  associated  with  the  Company's
discontinued  engineering  operations,  restructuring  charges  and  asset
impairments.  These  items are discussed in more detail below. The 2002 and 2000
results  also  include  amounts  associated with discontinued operations. Income
(loss)  from  continuing  operations  was  $8.9 million, $(.2) million and $16.6
million  for 2002, 2001, and 2000, respectively.  Earnings (loss) per share from
continuing  operations  was  $0.48,  $(0.01)  and $0.89 for 2002, 2001 and 2000,
respectively.  All  references  to  earnings  or  loss  per  share  ("EPS")  in
Management's  Discussion  and  Analysis  are on a diluted basis. For information
related  to the calculation of diluted EPS, refer to Note 10 of the Notes to the
Consolidated  Financial  Statements.
     As  discussed  above,  operating  results for  2001  include unusual items,
including  losses associated with discontinued operations, restructuring charges
and  asset  impairments.  During  the  fourth quarter of 2001, the Company began
plans to redirect its business strategy. The plans included the restructuring of
corporate,  business  unit and operational structures, including the integration
of  the Company's Alaska and Michigan gas distribution divisions. The plans also
included the closure of the Company's Houston-based engineering and construction
headquarters  and  the  related  consolidation  of  administrative  functions in
Michigan.  The  divestiture  of  the Company's engineering services business was
also part of the restructuring plan and has been accounted for as a discontinued
operation.  Operating  results,  net  of  income  taxes,  from  the discontinued
operations were $(1.1) million and $0.1 million for 2001 and 2000, respectively.
In  the fourth quarter of 2001, the Company recorded a loss of $5.0 million, net
of  income  taxes,  for  the estimated loss the Company expected to incur on the
disposal  of  its  engineering business segment, including estimated losses from
operations  during  the phase-out period. In November 2002, the Company sold its
engineering  services  business.  There was a difference of $10 thousand between
the  actual  losses  and the estimated losses, which is included in discontinued
operations  for  2002.
     In  addition  to  the  losses  from  discontinued operations, the Company's
results  for  2001  include restructuring charges, asset impairments and certain
other unusual items that reduced net income by $5.1 million, or $0.28 per share.
The  restructuring charges and asset impairments account for $4.0 million of the
charges,  net  of  income taxes, and include severance expense, costs associated
with  terminating  leases,  write-downs  of  certain construction operations and
other related expenses associated with the redirection of the Company's business
strategy.  The  other unusual items account for $1.1 million of the charges, net
of  income taxes, and include the write-off of certain assets and an increase in
reserves  for  certain  contingencies.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

     The  2001  restructuring charges and asset impairments ($6.1 million before
income  taxes)  are  reflected  in  operating  expenses  in  the  Company's 2001
Consolidated  Statement  of Operations. The other unusual items are reflected in
both  operating  expenses  ($.9  million  before income taxes) and non-operating
expenses  ($.6  million  before  income  taxes).  For  2001  business  segment
reporting,  the  operating income of the gas distribution business includes $1.1
million of the charges; the operating loss of the construction services business
includes  $3.3  million  of  the  charges;  and $2.6 million is reflected in the
operating  loss  of  the  corporate  and  other  business  segment.
     The  business  segment  analyses  and other discussions on the next several
pages  provide  additional  information  regarding  the differences in operating
results  when  comparing  2002,  2001  and  2000.  The following table shows the
Company's  consolidated  operating  results  for  the  past  three  years.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

THE  IMPACT  OF  WEATHER

The  Company's  largest  business  segment is natural gas distribution and, as a
result, temperature fluctuations have a significant impact on operating results.
The  Company  believes  that information about the estimated impact on operating
results  of  warmer  or  colder  than  normal  temperatures  is useful for fully
understanding  the  Company's  gas distribution business. The Company's budgets,
forcasts  and  business  plans  are  prepared  by management using  expected gas
consumption  under  normal  weather  conditions  as  a  central assumption.  The
regulatory  bodies  which  have  jurisdiction  over  the  rates  charged  by the
Company's gas distribution business, use weather-normalized data to set customer
rates and to establish authorized rates of return.  In addition, variations from
normal  weather  conditions can have a significant impact on the earnings of the
Company.  Therefore,  information about the estimated impact of warmer or colder
than  normal  weather  is  helpful in understanding the expected earnings of the
Company.
     The  Company  estimates  the  impact of weather on its operating results by
comparing  actual gas consumption per customer during a period to the average of
weather-normalized  customer  gas  consumption  during  previous  periods.  The
difference is multiplied by the average number of customers during the period to
arrive  at  the  total  estimated increase or decrease in consumption associated
with  weather.  The  total  increase or decrease in consumption is multiplied by
the  actual  margin  per  unit of consumption during the period to arrive at the
estimated  impact  of  weather  on  operating  results  for  the  period.  The
weather-normalized  customer  consumption used in this calculation is determined
by  multiplying  actual customer gas consumption during a particular period by a
ratio,  the  numerator  of  which  is  an average of degree days during the same
periods  in  the prior fifteen years, and the denominator of which is the actual
degree  days  for  that  period.
     The  Company  determines  the  percent (%) that weather is warmer or colder
than  normal for a particular period by computing the deviation of actual degree
days  for that period from the average of degree days during the same periods in
the prior fifteen years and dividing the deviation by such fifteen year average.
Degree  days are a measure of coldness determined daily as the number of degrees
the  average  temperature  during  the  day  in  question  is  below  65 degrees
fahrenheit.  Degree  days  for  a particular period are determined by adding the
degree  days  incurred  during  each  day  of  that  period.
     The  Company  has estimated that warmer than normal weather reduced the gas
sales  margin  of  its  gas distribution business by approximately $5.9 million,
$8.4 million and $6.5 million in 2002, 2001 and 2000, respectively. Adjusted for
income  taxes,  the estimated impact would have been approximately $3.6 million,
$5.3  million  and  $3.9  million,  respectively.


SUMMARY  OF  BUSINESS  SEGMENTS

The  Company  operates  four reportable business segments: (1) gas distribution;
(2) construction services; (3) information technology services; and (4) propane,
pipelines  and  storage.  The  latter  three  segments are sometimes referred to
together  as  the "diversified businesses." Refer to Note 11 of the Notes to the
Consolidated  Financial  Statements  for  further  information  regarding  each
business  segment  and  a  summary of financial information by business segment.
     Each  business  segment is discussed separately on the following pages. The
Company  evaluates  the  performance of its business segments based on operating
income.  Operating  income  does  not  include  income  taxes, interest expense,
discontinued  operations,  or  other  non-operating  income and expense items. A
review  of  the  non-operating  items  follows the business segment discussions.


GAS  DISTRIBUTION

The  Company's  gas  distribution  business  segment  consists  of operations in
Michigan  and  Alaska. The Michigan operation is sometimes referred to as "SEMCO
Gas"  and  the  Alaska  operation  is  sometimes  referred to as "ENSTAR". These
operations  are  referred  to  together as the "Gas Distribution Business". Warm
weather  during  the  past three years has had a significant impact on operating
income.  Weather was approximately 3%, 9% and 6% warmer than normal during 2002,
2001  and  2000,  respectively.

GAS  SALES  MARGIN.  During 2002, gas sales margin increased by $4.8 million (or
4%)  when  compared  to  2001.  The  increase was due primarily to the impact of
colder  weather,  increased  gas cost savings, the addition of new customers and
customers switching from the Company's aggregated transportation service ("ATS")
program  back  to  gas  sales service.  These items were offset partially by the
impact  of a reduction in customer rates at ENSTAR, effective in September 2002.
During  2001, gas sales margin decreased by $.9 million (or 1%) when compared to
2000.  The  decrease  was  due  primarily  to the impact of warmer weather and a
decrease  in gas cost savings, offset partially by the addition of new customers
and customers switching from the Company's ATS program back to general gas sales
service.
     Under  the terms of certain of the Company's third-party natural gas supply
and  management agreements for its Michigan operations, certain gas cost savings
are  retained  by  the  Company.  Gas cost savings were lower in Michigan during
2001, when compared to 2000, primarily as a result of purchasing gas with higher
thermal content during the first half of 2001. During the last half of 2001, the
thermal  content of purchased gas returned to 2000 levels. The Company purchases
its  gas  on a thermal basis, but must sell it to most customers on a volumetric
basis  (see Outlook for Gas Distribution section below regarding proposed change
to  thermal rates). An increase in thermal content also causes a decrease in gas
sales  because gas with a higher thermal content requires less volume to produce
the same amount of heat.  When the thermal content increases, the Company has to
pay  more  for  the  gas  but must still sell it based on volume.  Other factors
contributing  to  the  increase  in gas costs in 2001 were the release of excess
pipeline  capacity  in  2000, which reduced the Company's 2000 gas costs, and an
increase  in  unaccounted-for  gas.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

     The  increase  in  gas  cost  savings  during  2002,  the majority of which
occurred  in  the  first  quarter  of  2002,  was  due  in part to the effective
management  of  the Company's gas supply under certain of the third-party supply
and  management  agreements.  In  addition,  as  discussed  previously, gas cost
savings  were lower during 2001, compared to 2000, as a result of purchasing gas
with  a  higher  thermal content. Partially offsetting the increase in gas costs
savings  that  occurred  during the first quarter of 2002, was a decrease in gas
cost  savings  after  March  31,  2002  as  a result of reinstating the gas cost
recovery  ("GCR")  pricing  mechanism,  effective  April  1, 2002, for customers
subject  to the jurisdiction of the Michigan Public Service Commission ("MPSC").
As  a  result  of  reinstating  the GCR pricing mechanism, the Company no longer
retains  the  gas  cost  savings  on sales to customers located in jurisdictions
regulated by the MPSC ("MPSC Customers").  A significant portion of the gas cost
savings  realized  during  the first quarter of 2002 is non-recurring because it
relates  to  MPSC  Customers.  For  further  information regarding the Company's
natural  gas  supply  and  management  agreements,  gas cost savings and the GCR
pricing  mechanism,  refer  to the Cost of Gas section of Note 1 of the Notes to
Consolidated  Financial  Statements.
     The ATS program for residential customers was effective from April 1, 1999,
through  March  31,  2002.  The  ATS  program was further expanded and opened to
additional  customers  on October 1, 2002, as the customer choice program. These
programs  provide all Michigan residential customers the opportunity to purchase
their  gas  from  a  third-party  supplier,  while allowing the Gas Distribution
Business  to continue charging the existing distribution fees and customer fees.
Distribution  and  customer  fees  associated  with  customers  who  switched to
third-party  gas  suppliers  were  recorded in gas transportation revenue rather
than  gas  sales  revenue,  because the Company acted as a transporter for those
customers.  During  2001  and  2002,  certain ATS customers switched back to the
Company's  gas  sales  service  because  the  third-party  suppliers  they  were
utilizing stopped participating in the ATS program, primarily due to significant
fluctuations  in  the  market  price  of natural gas.  In addition, when the ATS
program  for  residential  customers  ended on March 31, 2002, all remaining ATS
customers  became  gas  sales  customers  because  they  were turned back to the
Company by their third-party gas suppliers.  As customers switch back to general
gas  sales service, gas sales revenue and gas sales margin increase but there is
a  corresponding  decrease  in  gas  transportation  revenue.
     During  2002, the Company's average number of gas sales customers increased
by  11,554.  Approximately  3,200  of  the  increase  was  caused  by  customers
switching  from the ATS program back to general gas sales service. The remaining
increase  of  approximately 8,400 represents the average number of new gas sales
customers  added to the Company's distribution system in 2002.  During 2001, the
Company's  average  number  of  gas  sales  customers  increased  by  11,274.
Approximately  2,800  of the increase was caused by customers switching from the
ATS  program  back  to  general  gas  sales  service.  The remaining increase of
approximately  8,500  represents  the  average number of new gas sales customers
added  to  the  Company's  distribution  system  in  2001.
     The  reduction  in customer rates at ENSTAR was required by an Order issued
by  the  Regulatory  Commission of Alaska ("RCA") dated August 8, 2002.  The RCA
Order  was  based  on  an  RCA  rate  review.  The rate reduction took effect in
September  2002  and  generally  reduces  gas  sales  margins  at  ENSTAR  by
approximately  3.6%.  Refer to Note 2 of the Notes to the Consolidated Financial
Statements  for  additional  information  about  the  Order.

GAS  TRANSPORTATION  REVENUE.   In 2002, gas transportation revenue decreased by
$.2  million  when  compared  to  2001. The primary factors contributing to this
decrease were a decrease in transportation volumes for power companies in Alaska
and the impact of ATS customers switching from the ATS program back to gas sales
service  in  Michigan.  As  discussed  above, under the ATS program, the Company
charged  ATS  customers  the  same distribution fees and customer fees that were
charged to gas sales service customers.  These items were partially offset by an
increase  in  industrial  and  commercial transportation volume when compared to
2001.
     In 2001, gas transportation revenue decreased by $4.9 million when compared
to  2000.  The decrease was primarily the result of customers switching from the
ATS  program  back  to the Company's general gas sales service and a decrease in
standard transportation revenue. The decrease in standard transportation revenue
was due to reduced consumption as a result of the softening economy and a few of
the  Company's  industrial and large commercial customers  in Michigan switching
to  alternative  fuels  earlier  in  2001,  due  to  high  natural  gas  prices.

OTHER OPERATING REVENUE.   During 2002, other operating revenue increased by $.3
million,  when  compared  to 2001. The increase was due primarily to fees on new
transmission  pipelines  in service in Michigan, offset partially by a reduction
in  ATS  balancing fees as a result of ATS customers switching back to gas sales
service.  During  2001,  other  operating  revenue decreased by $.7 million. The
decrease  was  due primarily to a reduction in ATS balancing fees as a result of
ATS  customers  switching  back  to  general  gas  sales  service.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

OPERATING  EXPENSES.  During  2002,  operating  expenses of the Gas Distribution
Business  decreased  by  $3.8  million  (or  4%)  when  compared  to  2001.  A
restructuring  charge  recorded  in  December 2001, most of which was made up of
employee  severance  expense associated with workforce reductions, accounted for
$1.1  million of the decrease for 2002. The remainder of the decrease was due to
a  number  of offsetting factors. Amortization expense decreased by $3.6 million
when  compared  to  2001.  The  decrease  was due to the elimination of goodwill
amortization as a result of the adoption of SFAS 142. For further information on
SFAS 142 and its impact on goodwill, see Note 1 of the Notes to the Consolidated
Financial  Statements.  Operation  and  maintenance  expense  decreased  by $1.2
million  due  primarily  to  general  cost  cutting measures and the impact of a
reduction  in  workforce  and  other  cost  reductions  related to the Company's
redirected business strategy, offset partially by higher employee benefit costs,
including  pension  expense,  health  care  costs  and retiree medical costs and
increased  maintenance costs. Property and other taxes increased by $.3 million,
due  primarily  to  property  taxes  on additional property, plant and equipment
placed  in service.  Depreciation expense increased by $1.7 million, also due to
additional  property,  plant  and  equipment  placed  in  service.
     During  2001, operating expenses of the Gas Distribution Business increased
by  $6.0  million  (or  7%)  when  compared  to  2000. The restructuring charge,
discussed  above,  accounted for $1.1 million of the increase. The 2001 increase
also  included  a  $.9 million increase in depreciation and amortization expense
due  primarily to additional property, plant and equipment placed in service and
a  $2.8 million increase in operation and maintenance expenses.  The increase in
operation  and  maintenance  expenses  was  due  primarily  to  increased
employee-related  costs  such  as  health  care costs, retiree medical costs and
pension  expense  and  increased  maintenance  costs.
     In addition, there was a $1.2 million increase in 2001 general business tax
expense.  The  increase was due primarily to property tax reductions recorded in
2000  and  higher  property  taxes  in  2001,  because of additional property in
service.  The  property  tax  reductions  of  $2.1 million in 2000 were based on
pending  appeals of prior years' (1997 - 1999) personal property tax assessments
in  Michigan  ("prior  year  tax  appeals")  and  new  property valuation tables
approved  by  the  State  of  Michigan  in 1999 ("new property tax tables"). The
Company  filed  the  appeals  over  the  past  several  years, claiming that its
Michigan  utility  property  was  over-assessed.  The  new  property  tax tables
approved  by  the  State  of  Michigan  are  consistent with the Company's claim
regarding  its utility property assessments, and thus significantly increase the
likelihood  of  recovering the overpaid property taxes. See Note 13 of the Notes
to  the  Consolidated Financial Statements for further information regarding the
prior  year  tax  appeals  and  recoverability  of  overpaid  property  taxes.

OUTLOOK  FOR  GAS DISTRIBUTION.  The Company's strategy for the Gas Distribution
Business  is  to  expand its distribution system in an economical manner through
attachment  of  on-main and near-main potential customers. The Company will also
seek  ways  to  capitalize  on  other  market opportunities, including new power
generation  projects that may become available.  The average number of customers
served by SEMCO Gas and ENSTAR, combined, increased by approximately 2.3% during
both  2002  and  2001.  By  comparison,  recent  surveys  by  the  American  Gas
Association indicate that the customer growth rate for the U.S. gas distribution
industry  has  averaged  approximately  1.8% annually during the last ten years.
However,  average  annual  gas  usage  per customer has been decreasing slightly
because  new  homes  and  appliances  are  more  energy  efficient.
     The Company has offered early retirement programs during the past few years
to help reduce costs. The increased use of technology has also created operating
efficiencies.  In  addition,  the  Gas  Distribution  Business  eliminated  its
unprofitable  Heating,  Ventilation  and Air Conditioning ("HVAC") department in
2001  and  also  eliminated  other  employee  positions as part of the Company's
restructuring  plan.  The Gas Distribution Business will continue its efforts to
control  operating  expenses.
     SEMCO  Gas  competes  with  suppliers of alternative energy sources such as
coal  and  #6  and #2 fuel oil to meet the energy requirements of its industrial
customers.  Natural gas has typically been less expensive than these alternative
energy  sources.  However,  during a short period of time in late 2000 and early
2001,  natural  gas  prices  increased  significantly,  making  some  of  these
alternative  energy  sources  more  economical  than  natural  gas.  During this
period,  a  few of the Company's large Michigan industrial customers switched to
alternative  energy  sources. This competition did not have a material impact on
the financial results of the Company in 2001. Prior to 2000, the market price of
natural  gas  had  been  fairly  stable. However, the Company cannot predict the
future  stability  of  natural  gas  prices.  To  lessen the possibility of fuel
switching  by  industrial  customers, the Company offers flexible contract terms
and  additional  services,  such  as gas storage and balancing, in addition to a
more  environmentally  friendly fuel. ENSTAR supplies natural gas in its service
territory  at  prices that currently preclude substitution of alternative energy
sources.  At  present,  the  residential energy cost of natural gas in Alaska is
less  than  half  the  cost of fuel oil, the next most economical energy choice.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

     General  economic  conditions also have an impact on the volume of gas sold
or  transported  to  the  Company's  commercial and industrial customers. During
economic  downturns,  these  customers  may  see  a decrease in demand for their
product,  which in turn may lead to a decrease in the amount of natural gas they
require  for  production.  However,  under  normal  weather  conditions, the Gas
Distribution  Business  generates  approximately  68  percent  of  its gas sales
revenues  from  residential  customers who use natural gas for heating purposes,
which  is  generally  not  impacted  materially  by  downturns  in  the economy.
Temperatures,  however,  do have an impact on the amount of gas sold for heating
purposes.
     Consistent with other gas distribution utilities, there is a potential risk
that industrial and electric generating plants on the Company's gas distribution
system, and also located in close proximity to interstate natural gas pipelines,
will  bypass  the  Company  and  connect  directly  to  such pipelines. However,
management  is  currently  unaware  of  any  significant  bypass  efforts by the
Company's customers. The Company has addressed and would continue to address any
such  efforts  by  offering  special  services and rate arrangements designed to
retain  these  customers  on  the  Company's  system.
     On  November  21,  2002 the Company filed an application for a general rate
increase  of  $10.9 million for the MPSC regulated division of SEMCO Gas.  Among
the  principal  reasons  for  the  requested  increase  were  higher pension and
healthcare costs and investment of approximately $120 million in new plant since
the  last  rate  increase  was  approved  in 1997.  In addition to specific rate
relief,  the  application sought an innovative rate design, which would mitigate
some  of  the  effects  of warmer than normal weather on the company's earnings.
This  new  rate  design calls for greater recovery of fixed costs in the monthly
customer  charge  and  declining block rates for gas sales customers. This would
provide  more  stability in customer bills by moving costs from the peak heating
season to summer and off-peak heating months.  The filing also requests a change
to  customer billing based on the heat content of natural gas, or therms, rather
than the current volumetric measure, cubic feet. Any changes resulting from this
rate  case  likely  would  be  made  in 2003.  This rate case does not cover the
division of SEMCO Gas that is subject to the regulatory jurisdiction of the City
Commission  of  Battle  Creek  ("CCBC").
     The  Company  received  an  Order  dated August 8, 2002 from the RCA on its
review  of  rates for ENSTAR, based on normalized data for the year 2000. In its
Order  the  RCA established a revenue requirement of $107.6 million and a 12.55%
return  on  equity.  In  response  to  a  petition  by ENSTAR, the RCA issued an
additional  Order  dated  September 16, 2002, which revised the indicated annual
revenue reduction from $2.1 million to $2.0 million, which was 1.84% of ENSTAR's
revenue in the normalized 2000 test year. The Order required ENSTAR to implement
the  rate  reduction by September 27, 2002 on an across-the-board basis. The RCA
also  required  ENSTAR  to file an updated cost of service study by September 9,
2002  and  a  rate  design  in  December 2002, with a hearing on the rate design
filing  scheduled  for  May  2003. ENSTAR has implemented the rate reduction and
filed both the cost of service study and the rate design as required.   The rate
design  filed  with the RCA by ENSTAR is similar to the rate design requested in
the  MPSC rate case.  It includes greater recovery of fixed costs in the monthly
customer  charge  and  declining  block  rates  for  gas  sales  customers.
     For further information regarding environmental matters, regulatory matters
and  the application of SFAS 71, "Accounting for the Effects of Certain Types of
Regulation,"  refer to Notes 2 and 13 of the Notes to the Consolidated Financial
Statements  and  the  Critical  Accounting  Policies  section  near  the  end of
Management's  Discussion  and  Analysis.


CONSTRUCTION  SERVICES

The  Company's  construction  services  segment  ("Construction  Services") does
business  in  the  midwestern,  southern  and  southeastern  areas of the United
States.  Construction  Services generates the majority of its sales revenue from
the  installation and upgrade of natural gas compressor stations and underground
natural  gas  mains  and  service lines. Underground construction businesses are
seasonal  in  nature.  As  a  result,  Construction  Services  generally  incurs
operating  losses  during  the  winter  and  spring  months  when  underground
construction  is  inhibited  by  weather,  and  generates  the  majority  of its
operating  revenue  and  operating  income  during  the  summer and fall months.

OPERATING  REVENUES.  Construction Services revenues decreased to $119.3 million
during  2002, a $7.0 million (or 6%) decrease from 2001. The decease during 2002
was  due  in  part  to customers in the northern regions of the country delaying
projects  in  2002  in  light  of  the generally depressed economy and their own
financial  considerations.  Operating  revenues  in  the  southern region of the
country  were  up  significantly  during  the  first  half of 2002, due to large
projects  in that region.  However, during the second half of 2002, customers in
the  southern  region of the country also delayed a number of these projects for
the  same reasons discussed above. Construction Services operating revenues were
$126.2  million for 2001, which was a $21.0 million (or 20%) increase over 2000.
The increase during 2001 was due primarily to large construction projects in the
southeastern  region  of  the  United  States  as well as increased construction
revenue  in  other  regions  of  the  country.

OPERATING  INCOME.  Construction  Services had an operating loss of $2.0 million
for  2002,  compared to an operating loss of $1.4 million for 2001 and operating
income  of  $3.7  million  in  2000.  Excluding  restructuring  charges,  asset
impairments and other unusual charges of $3.3 million, Construction Services had
operating  income  of  $1.9  million  in  2001. The restructuring and impairment
charges  and  other  unusual  items include the write-down of goodwill and fixed
assets  of  certain construction operations, severance expense and other related
charges.
     The  operating  loss  of $2.0 million for 2002 represents a decline of $3.9
million  from  the  $1.9 million of operating income, excluding unusual charges,
reported  for  2001.  The  decrease  is  due  primarily  to reduced construction
activity during all of 2002 in the northern region of the country and during the
last  half  of  2002  in  the  southern region of the country.  In addition, the
Company  experienced  lower  than expected margins on some of the work performed
and  higher  than anticipated costs on some projects.  The Company believes that
the  softening  economy  has  caused  many  customers to delay or cancel certain
construction  projects,  which changed the mix of work available to Construction
Services.  The  mix  of work included more lower-margin work at certain business
units  because  of the competition for the limited supply of available work. The
reduced  construction  activity  has also eroded margins because of the time lag
required to reduce the staffing levels and other fixed costs which were required
for  the  previously  higher  level  of  revenues.  Certain fixed costs were not
eliminated  for  a  number of reasons, including the expectation that work would
resume  on  many  of  the  projects.  In  addition, the operating performance in
certain  regions  of  Construction  Services  has  been  below  the  Company's
profitability  expectations.  These  factors  were offset partially by operating
income  generated  from  the  increase  in construction projects in the southern
regions  of  the  United  States  during  the  first  half  of  2002.
     The  $1.8  million  decrease  in  2001  operating income, excluding unusual
charges, when compared to 2000 operating income, was due primarily to the mix of
available  work  and the softening economy, as discussed above. In addition, the
softening  economy  reduced  new  housing  starts during 2001 in the areas where
Construction  Services  does  business, which caused a decrease in the number of
new  gas  service  lines available for installation, when compared to 2000.  The
factors  causing  the decrease in 2001 operating income were offset partially by
profits  on  the  large projects, discussed above, in the southeastern region of
the  country  during  the  last  half  of  2001.

OUTLOOK  FOR  CONSTRUCTION  SERVICES.   Despite the decline in operating results
during  the  past  two  years,  management  believes there are opportunities for
growth  in  its  segment  of  the  pipeline  and  gas  distribution construction
industry.  Management believes that the current business downturn is short-term,
driven, in part, by the state of the U.S. economy, financial issues faced by the
Company's  construction  customers,  and poor productivity in certain regions of
the construction services business.  In late 2002, the Company ceased operations
in  a  number  of  under-performing  regions,  which  will eliminate from future
results  the  operating  losses  Construction Services incurred in these regions
during  2002.  In  addition,  plans are underway which the Company believes will
improve  construction  work  crew  productivity  in  2003.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

     The  Company  believes  that  the  increasing  demand  for natural gas will
sustain  a  continued,  long-term  increase  in  the  need  for  natural  gas
infrastructure  expansion.  Management  continues  to view the industry as large
but  highly  fragmented  and  believes that customer preference is shifting from
smaller  construction  companies to larger contractors. Management also believes
there  is  a  trend in the utility industry towards outsourcing services such as
those  provided  by  Construction  Services.  The  Company's goal is to position
Construction  Services  to  take  advantage  of  these  trends.
     Construction  Services  competes with small, medium and large-size regional
underground  facilities  contractors  who  provide  similar services and utilize
comparable equipment and installation techniques. There is also competition from
in-house  construction  operations  of  existing  or  prospective customers. New
federal  regulations  in  the  United States require a minimum level of operator
qualifications  for  individuals  performing  certain  tasks  on pipelines.  The
Company  believes that the costs and training required for compliance with these
new  regulations may force some of Construction Services' smaller competitors to
abandon  certain  pipeline  work.
     General  economic  conditions also have an impact on the amount and type of
work  available  for  Construction  Services.  During  economic  downturns,  new
housing  starts often decline, which leads to a decrease in new gas service line
installations.  Customers  may  also  reduce  amounts  typically  spent  for
non-essential  construction  projects,  which  also  leads to a decrease in work
available  to  Construction  Services.
     As  discussed previously, the Company has redirected its business strategy.
Under  this redirected strategy, the Company's goal for Construction Services is
to  expand  its  market  share  by focusing on profitable growth of its existing
construction  businesses,  with  less  emphasis  on acquisitions. This change in
focus  is  intended  to redirect resources to help maximize the profitability of
existing  businesses.  As  part  of  its  strategic redirection, the Company has
stopped  doing business in certain regions that were not contributing profitably
to  the  organization.  The Company has also consolidated certain regions of its
construction  services  operations  and  continues  to look for opportunities to
become  a  more  integrated  business.


INFORMATION  TECHNOLOGY  SERVICES

The  information  technology  business  ("IT  Services"),  under  the  Aretech
Information  Services  name  ("Aretech"),  began operations in April of 2000 and
provides  IT  infrastructure  outsourcing services, and other IT services with a
focus  on  mid-range computers, particularly the IBM I-Series (AS-400) platform.

The  amounts  in  the  above  table  include  intercompany  transactions.



OPERATING  REVENUES.  Operating  revenues  were $9.6 million, $10.3 million, and
$5.2  million  in  2002,  2001  and  2000,  respectively.  Of these amounts $7.6
million,  $9.3  million  and $5.0 million for 2002, 2001 and 2000, respectively,
represent  sales to affiliates.  The decrease in revenues in 2002, when compared
to  2001,  was due primarily to fewer special projects with affiliate customers,
offset  partially  by an increase in business with non-affiliates.  The increase
in  revenues  in  2001, when compared to 2000, was due primarily to providing IT
services  for  all  affiliates  of the Company and the addition of non-affiliate
customers.  During  the  first  several  months of its operation in 2000, the IT
services  business  was  primarily  providing  services  to  the  Michigan  gas
distribution  operation  and  the  Company's  corporate  office.  Non-affiliate
operating revenues were $2.0 million, $1.0 million and $.2 million in 2002, 2001
and  2000,  respectively.

24 -- SEMCO ENERGY, INC. AND SUBSIDIARIES



MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

OPERATING  INCOME.  Operating  income  for  the IT business was $.6 million, $.4
million  and  $.5 million for 2002, 2001 and 2000, respectively. The increase in
2002  when  compared  to  2001  is due primarily to an increase in business with
non-affiliate  customers  and  a  decrease  in  indirect  operating  expenses,
particularly advertising costs.  The decrease in 2001, when compared to 2000, is
due  primarily  to  more  special  project services performed during 2000, which
typically  is  higher  margin  work.

OUTLOOK FOR IT SERVICES.  The Company believes there is a growing trend by small
to  mid-sized  companies  to outsource certain information technology functions.
The  Company  believes  the  trend towards outsourcing large mainframe-computing
services  is now moving to include mid-range computers. The Company's goal is to
capitalize  on its internal expertise in this area and position this business to
take  advantage  of  these  trends. Aretech's business strategy is focused on IT
infrastructure  outsourcing  services.
     Aretech competes with businesses that range from small local firms to large
international  companies,  as  well  as the in-house IT departments of potential
customers.  Aretech  is  an early provider in the mid-range computer outsourcing
market  and, as the market expands, it is likely that new competition will arise
from  other  firms  that  possess  the  necessary  technical  skills.


PROPANE,  PIPELINES  AND  STORAGE

The  Company's  natural  gas  pipeline and storage operations consist of several
transmission  pipelines and an ownership interest in a gas storage facility, all
of  which  are located in Michigan. The Company also owns a propane distribution
business  ("Hotflame"),  which  sells  more than 4 million gallons of propane to
retail  customers  in  Michigan's  upper  peninsula  and  northeast  Wisconsin.

and  $1,186,000  in  2002,  2001  and  2000, respectively.  The equity income is
reflected  in  other  income  and  deductions.



OPERATING  REVENUES.   Operating revenues were $7.1 million in 2002, compared to
$7.4 million in 2001 and $6.9 million in 2000. The decrease in revenues in 2002,
when  compared to 2001, was due primarily to lower propane distribution revenues
resulting  from  a  reduction  in the market price for propane.  The increase in
revenues  in  2001,  when  compared to 2000, was due primarily to higher propane
distribution revenues resulting from an increase in the market price of propane.

OPERATING  INCOME.  The operating income of the Company's Propane, Pipelines and
Storage  segment  for  2002  and 2001 was essentially unchanged at $1.9 million.
Operating  income  for  2000  was  $1.5 million.  The increase during 2001, when
compared  to  2000  was  due  primarily  to  lower operating expenses and higher
propane  margins.
     Weather  in Hotflame's market area was warmer than normal in 2002, 2001 and
2000.  The  impact  of weather on the operating income of the propane, pipelines
and  storage  segment  relates  only  to  the  propane  business.

OUTLOOK  FOR  PROPANE,  PIPELINES AND STORAGE.  Management believes that the gas
pipeline  and  storage operations could experience opportunities for growth with
the  increased deregulation of gas markets and the increasing demand for natural
gas.  As  gas  markets  expand  or are deregulated, management believes that the
quantity of gas moving through the Great Lakes Region will increase, which could
create  additional  pipeline  and  storage  opportunities.
     The  Company's  propane  business competes with other regional and national
propane  providers  and  with other energy sources such as natural gas, fuel oil
and  electricity.

INTEREST  EXPENSE.  Interest  expense  decreased  by $.5 million (or 2%) in 2002
when  compared  to  2001.  The  decrease  is  due  primarily to lower short-term
interest  rates  and  a reduction in interest expense as a result of an interest
rate  swap  agreement  which  was  entered into in August 2001 and terminated in
August  2002.  However,  these  items  contributing  to the decrease in interest
expense  were offset partially by incremental interest on additional debt issued
in  2001.  The interest rate swap referred to above was entered into in order to
hedge the Company's $55 million 8% Notes due in June of 2004.  During the period
prior to terminating the swap, the floating interest rate under the terms of the
swap  agreement steadily declined, which reduced the Company's interest expense.
The  Company  received  $2.2 million in proceeds when the interest rate swap was
terminated in August 2002, which is being recognized pro-rata, as a reduction to
interest  expense,  over the remaining term of the 8% Notes due in June of 2004.
     Interest expense decreased by $3.1 million (or 8.9%) in 2001, when compared
to  2000.  The  decrease  is  due  primarily to lower debt levels as a result of
refinancing  the  $290  million  short-term  bridge  loan, which was utilized to
finance  the  November  1,  1999  acquisition of ENSTAR, with various securities
offerings  during  the  second  and  third quarters of 2000. The bridge loan was
outstanding during the first half of 2000.  During the last half of 2000 and all
of  2001,  the  Company  had  an  equivalent  amount of long-term debt and trust
preferred securities outstanding. As a result, interest expense was less in 2001
primarily  because  the dividends on the trust preferred securities are reported
separately  from  interest  expense. Lower short-term interest rates during 2001
also  contributed  to  the  overall decrease in interest expense. However, these
factors  were  partially  offset  by  $2.1  million of non-recurring income from
terminated interest rate swaps, reflected in 2000 interest expense, and interest
on additional debt incurred in 2001 to finance the Company's capital expenditure
programs.

OTHER  INCOME.  In  2002, other income decreased by $.1 million when compared to
2001.  A  number of offsetting factors contributed to the change.  A decrease in
allowance  for  funds  used  during  construction  ("AFUDC") and interest income
reduced  other  income  during 2002.  Partially offsetting these factors was the
write-off  of certain assets in 2001, which did not recur in 2002, income earned
in  2002  on  a  special  engineering  project  completed  by  SEMCO  Gas  for a
third-party,  and  an  increase  in  equity  income  from an investment in a gas
storage  facility.
     During  2001,  other income decreased by $.5 million when compared to 2000.
The  decrease  was  due primarily to the write-off of certain assets in 2001 and
gains  on  property  sales  in  2000.  These factors were partially offset by an
increase  in  AFUDC and an increase in interest income. The increase in interest
income  was  the  result  of  interest  received  on  a supplier refund in 2001.


INCOME  TAXES

Income  taxes for 2002, 2001 and 2000 were $10.1 million, $6.6 million and $11.6
million,  respectively.  The  change in income taxes, when comparing one year to
another, is due primarily to changes in income before income taxes and dividends
on trust preferred securities, and any adjustments necessary for compliance with
tax  laws  and  regulations.  Refer  to  Note 3 of the Notes to the Consolidated
Financial Statements for information on current and deferred income tax expense,
deferred  tax  assets  and  liabilities, and recent net operating losses for tax
purposes.

CONDITION AND RESULTS OF OPERATIONS

DIVIDENDS  ON  TRUST  PREFERRED  SECURITIES

The  Company  issued  trust  preferred  securities  and FELINE PRIDES during the
second quarter of 2000. These securities are described in Note 4 of the Notes to
the  Consolidated  Financial  Statements.  Dividends on these securities, net of
income tax, were $8.6 million during 2002 and 2001 and $5.0 million in 2000. The
$3.6  million  increase  in  dividends  in  2001, when compared to 2000, was the
result  of a full year of dividends during 2001, in comparison to a half-year of
dividends  during  2000.


DISCONTINUED  OPERATIONS

In  December  2001, the Company's Board of Directors approved a plan to redirect
the  Company's  business  strategy, which, as discussed previously, included the
divestiture  of  its  engineering services business. The planned divestiture has
been  accounted  for as a discontinued operation and, accordingly, the operating
results  and  the loss on the disposal of this business have been segregated and
reported  as  discontinued  operations  in  the  Consolidated  Statements  of
Operations.  The Company completed the sale of its engineering services business
effective  November  1,  2002. For additional information, including a component
breakdown  of  operating  results  reflected  in discontinued operations and the
impact  of the sale in comparison to the estimated loss, refer to Note 14 of the
Notes  to  the  Consolidated  Financial  Statements.

     non-cash  amounts  such  as  deferred  payments  and value, at the time of
     issuance, of Company stock issued as part of the acquisitions.



     Property  additions  for  the Gas Distribution Business represent primarily
gas  service  lines  for  new  customers  and,  to a lesser extent, gas main and
service  line replacements.  In addition, the Company invested approximately $.6
million,  $5.9  million  and $11.9 million in technology in 2002, 2001 and 2000,
respectively.  This  technology consists of automated meter reading, measurement
systems  and  other  computer  system  and infrastructure improvements that have
increased  customer  service  and administrative and operational efficiency. The
Company  acquired a business for approximately $1.8 million in 2000.  There were
no  acquisitions  in  2001  and  2002.  In  2003,  the  Company  plans  to spend
approximately  $33  million  on  property  additions.
     During  2002,  the  Company received $4.5 million in proceeds from property
sales,  net  of  costs.  This  was a significant increase over prior years.  The
primary  reason  for the increase was the sale of two buildings and vacant land.
The  two  buildings  housed a large portion of the operations and administrative
personnel  of  SEMCO  Gas.  These  two  facilities  are  now being leased by the
Company.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

CASH FLOWS PROVIDED BY OPERATIONS.  The Company's net cash provided by operating
activities  totaled  $24.9  million  in  2002,  $36.7  million in 2001 and $49.0
million  in 2000. The change in operating cash flows is influenced significantly
by  changes  in  the  level  and  cost of gas in underground storage, changes in
accounts  receivable  and accrued revenue and other working capital changes. The
changes  in these accounts are largely the result of how the Company manages the
timing  of  cash  receipts  and  payments.
     The  Company  uses  significant amounts of short-term borrowings to finance
natural  gas  purchases  for  storage during the non-heating season. The Company
owns  and  leases  natural  gas  storage  facilities in Michigan, with available
capacity  approximating  30% to 35% of the Company's average annual Michigan gas
sales.  Generally,  gas  is  injected  into  storage  during the months of April
through  October  and  withdrawn  for  sale  from  November  through  March.

CASH  FLOWS  PROVIDED  BY  FINANCING.  The Company received net cash provided by
financing  activities  of $5.6 million, $19.3 million and $13.6 million in 2002,
2001  and  2000,  respectively.

     The  Company's  net  funds  borrowed  (paid)  on  notes  payable were $13.9
million,  ($26.2)  million  and  ($243.7)  million  in  2002,  2001  and  2000,
respectively.  During  2002 the Company issued $30 million of long-term debt and
used  the  proceeds to repay $30 million of debt which matured in October, 2002.
During  2001,  the  Company  issued  $60  million of long-term debt and used the
proceeds  to  repay  a  portion of its short-term lines of credit with banks. On
November  1,  1999,  the  Company financed the acquisition of ENSTAR with a $290
million  unsecured  bridge  loan.  In 2000, the Company utilized the proceeds of
several  securities  offerings  and its short-term bank lines of credit to repay
the  bridge loan. The net change in notes payable for 2000 includes the combined
cash borrowed or paid on the Company's short-term lines of credit with banks and
the  ENSTAR  bridge  loan.
     The  Company redeemed certain of its securities and issued various debt and
equity  securities  during the past three years. Refer to Note 4 of the Notes to
the  Consolidated  Financial  Statements  for  information  regarding  these
redemptions  and  issues.
     Cash dividends paid per share for common shareholders were $0.59, $0.84 and
$0.84  in  2002,  2001  and
2000,  respectively.

NON-CASH  FINANCING  ACTIVITIES.  The  Company  issued  .1 million shares of its
common  stock  to  the  shareholders  of  a  business  acquired  during  2000.

OFF-BALANCE SHEET ARRANGEMENTS.  The Company does not have any off-balance sheet
financing  arrangements.

GUARANTEES.  The Company does not have any material guarantees that are required
to  be  disclosed  under  the provisions of Financial Accounting Standards Board
Interpretation  No.  45,  "Guarantors Accounting and Disclosure Requirements for
Guarantees,  Including  Indirect  Guarantees  of  Indebtedness  of  Others."

CONTRACTUAL  OBLIGATIONS  AND  COMMERCIAL COMMITMENTS.  Summarized below are the
contractual  obligations  and  other  commercial  commitments  of  the  Company.

     Statements  for  further  information.



OTHER  COMMITMENTS  AND  CONTINGENCIES.  For information about other commitments
and  contingencies,  refer to Note 13 of the Notes to the Consolidated Financial
Statements.

FUTURE FINANCING.  In general, the Company funds its capital expenditure program
and  dividend  payments  with  operating  cash  flows  and  the  utilization  of
short-term  credit  facilities. When appropriate, the Company will refinance its
short-term  debt  with long-term debt, common stock or other long-term financing
instruments.  On  June  25, 2002, the Company entered into a $145 million credit
agreement  with  a  group of banks, replacing four lines of credit totaling $145
million,  which  were  due  to  expire.  The  new  agreement,  all  of  which is
committed,  consists  of  an  $80  million three-year revolver and a $65 million
364-day  facility,  with  a one-year term loan option. At December 31, 2002, the
unused  portion  of  the  Company's  credit  facility  was  $23.8  million.
     In  March  2000,  a  registration  statement  on  Form  S-3  ("registration
statement")  filed by the Company and SEMCO Capital Trust I, SEMCO Capital Trust
II  and  SEMCO  Capital  Trust  III  ("Capital  Trusts") with the Securities and
Exchange  Commission became effective. The Company and Capital Trusts registered
up to $500 million of securities under the registration statement, of which $276
million,  $60  million  and $30 million were utilized to issue securities during
2000,  2001  and 2002, respectively. The remaining balance of $134 million under
the  registration  statement is available for any future issues of common stock,
preferred stock, trust preferred securities and long-term debt, as needed. Refer
to  Note  4 of the Notes to the Consolidated Financial Statements for additional
information  regarding  the  securities  issued.
     Two  of the Company's securities, 10.1 million FELINE PRIDES securities and
$105  million  of  8.95%  Remarketable  or  Redeemable  Securities ("ROARS") are
subject  to  remarketing  and  rate resets in 2003. In addition, the Company may
also  redeem, or may be required to redeem, the ROARS during 2003. Refer to Note
4  of  the  Notes  to the Consolidated Financial Statements for a description of
these  securities  and  other  information,  including  the  terms  related  to
remarketing,  rate  resets  or  possible  redemption  of the securities in 2003.
     The  Company's long-term and short-term debt agreements contain restrictive
financial  covenants  including,  among  others,  maintaining  a  Fixed  Charges
Coverage  Ratio  (as  defined  in  the  agreements) of at least 1.50 and placing
limits  on  the  payment of dividends beyond certain levels. Non-compliance with
these  covenants  could  result in an acceleration of the due dates for the debt
obligations  under  the  agreements.  As of December 31, 2002, the Fixed Charges
Coverage  Ratio  was  1.89  and  the  Company  was in compliance with all of the
covenants in these agreements. The Company has currently projected its financial
covenants  for  each  of  the  four quarters during 2003, based on the Company's
forecasted  operating  results  for  the year, and these forecasted results show
that the Company would be able to remain in compliance with all of its covenants
during  2003.  However,  these  forecasted  results  are  dependent  on  several
internal  assumptions  and  external  factors.  If  these assumptions or factors
differ from management's current expectations, they could have an adverse impact
on the Company's ability to remain in compliance with its covenants during 2003.

- ----------
29 -- SEMCO ENERGY, INC. AND SUBSIDIARIES



MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

     The  most significant assumptions and factors that could impact the ongoing
compliance  with these covenants include the effects of weather on the Company's
operating  results;  the ability of the Company to improve the operating results
of  the  construction  services  business  under the Company's current strategic
direction;  the  ability  of  the  Company  to  refinance  its long-term debt in
accordance  with  its  financing plans; the ability of the Company to accomplish
its  financing  objectives  in  a  timely  and cost-effective manner in light of
changing  conditions  in  the  capital  markets;  and  the  Company's ability to
successfully  pass  its  annual  goodwill impairment tests in light of the these
factors.
     In  the  event  the  Company is not able to remain in compliance with these
covenants,  management  plans  to negotiate a modification of the covenants or a
waiver  of  certain  covenant  provisions.  However, the Company cannot make any
assurances  about  whether  modifications  or  waivers  can  be  negotiated.
     The Company's ratio of earnings to fixed charges, as defined under Item 502
of  SEC  regulations  S-K,  was  1.32,  1.04  and  1.60 for 2002, 2001 and 2000,
respectively.  This  ratio  is  more  strictly  defined  than  the Fixed Charges
Coverage  Ratio  used  to  determine  compliance  with  the Company's previously
discussed  debt  covenants.


MARKET  RISK  INFORMATION

The  Company's  primary market risk arises from fluctuations in commodity prices
and  interest  rates. The Company's exposure to commodity price risk arises from
changes  in  natural  gas and propane prices throughout the United States and in
eastern  Canada, where the Company conducts sales and purchase transactions. The
Company does not currently use financial derivative  instruments (such as swaps,
collars  or  futures)  to  manage  its  exposure  to  commodity  price  risk.  A
significant  portion  of  the natural gas requirements of the Company's Michigan
gas  distribution  operations  are covered under third-party supply arrangements
and  an  MPSC-approved  mechanism  that  passes  commodity  costs through to its
customers.  ENSTAR's  natural gas requirements are primarily covered by a number
of  long-term  supply  arrangements  and  an  RCA-approved mechanism that passes
commodity  costs through to its customers.  For further information on how these
agreements  reduce  the Company's exposure to commodity price risk, see the Cost
of  Gas section in Note 1 of the Notes to the Consolidated Financial Statements.
     The  Company  is  also subject to interest rate risk in connection with the
issuance  of  variable and fixed-rate debt. In order to maintain its desired mix
of  fixed-rate  and  variable-rate  debt, the Company may use interest rate swap
agreements  and  exchange  fixed  and variable-rate interest payment obligations
over  the  life  of the agreements, without exchange of the underlying principal
amounts.  See  Note  7 of the Notes to the Consolidated Financial Statements for
additional  information  on  the  fair value of interest rate swap agreements at
December  31,  2002,  and  how  the  Company  accounts  for  its risk management
activities.


IMPACT  OF  INFLATION

The  cost  of  gas  sold  in  Alaska  is recovered from natural gas distribution
customers  on  a  current  basis through its gas cost adjustment ("GCA") clause.
The  cost  of  gas  sold  in  the  geographic  areas  of Michigan subject to the
jurisdiction of the MPSC is recovered from natural gas distribution customers on
a  current  basis  through its gas cost recovery ("GCR") clause. The GCA and GCR
mechanisms allow for the adjustment of rates charged to customers in response to
increases  and  decreases  in the cost of gas purchased. The Company applied for
and received approval from the CCBC to extend the fixed gas charge program until
March  31,  2005 for customers located in the City of Battle Creek, Michigan and
surrounding  communities.  See the Cost of Gas section in Note 1 of the Notes to
the  Consolidated  Financial  Statements  for  more  information.
     Increases  in  other  utility  operating  costs  are  recovered through the
regulatory  process  of  a  rate  case  and, therefore, may adversely affect the
results  of  operations  in inflationary periods due to the time lag involved in
this  process.  The  Company  attempts  to  minimize  the impact of inflation by
controlling  costs,  increasing  productivity  and filing rate cases on a timely
basis.

CONDITION AND RESULTS OF OPERATIONS

CRITICAL  ACCOUNTING  POLICIES

The  Company  has  prepared  its Consolidated Financial Statements in conformity
with  accounting  principles  generally  accepted  in  the  United  States.  The
preparation  of these financial statements requires management to make estimates
and  assumptions  that affect the reported amounts of assets and liabilities and
disclosure  of  contingent  assets  and liabilities at the date of the financial
statements  and  the  reported  amounts  of  revenues  and  expenses  during the
reporting  period.  Actual  results  could  differ from those estimates.  In the
event  estimates  or  assumptions  prove  to  be  different from actual results,
adjustments  are made in subsequent periods to reflect more current information.
The  following  is a summary of the Company's most critical accounting policies,
which  are  defined  as  those policies whereby judgments or uncertainties could
affect  the application of those policies and materially different amounts could
be  reported  under  different  conditions or using different assumptions. For a
complete  discussion  of the Company's significant accounting policies, refer to
Note  1  of  the  Notes  to  the  Consolidated  Financial  Statements.

RATE  REGULATION.  The  Gas  Distribution Business is subject to regulation. The
regulatory  matters  associated  with  gas distribution customers located in the
City  of  Battle Creek, Michigan, and surrounding communities are subject to the
jurisdiction of the City Commission of Battle Creek. The Michigan Public Service
Commission has jurisdiction over the regulatory matters related to the Company's
remaining  Michigan customers. Regulatory matters for gas distribution customers
in  Alaska  are  subject  to  the  jurisdiction  of the Regulatory Commission of
Alaska.  These  regulatory  bodies  have  jurisdiction over, among other things,
rates,  accounting  procedures,  and  standards  of  service.
     The  Company's  gas  distribution  business segment has accounting policies
which  conform  to  SFAS  71,  "Accounting  for  the  Effect of Certain Types of
Regulation"  and  which  are  in accordance with the accounting requirements and
ratemaking  practices  of  the  regulatory authorities. The application of these
accounting  policies  allows  the  Company  to  defer  expenses  and  income  as
regulatory  assets  and  liabilities in the Consolidated Statements of Financial
Position  when  it is probable that those expenses and income will be allowed in
the  ratesetting  process  in  a  period different from the period in which they
would  have  been  reflected  in the Consolidated Statements of Operations by an
unregulated  company.  These deferred regulatory assets and liabilities are then
included  in  the  Consolidated Statements of Operations in the periods in which
the  same  amounts  are  reflected  in  rates.  Management's  assessment  of the
probability  of  recovery  or  pass through of regulatory assets and liabilities
requires  judgment  and interpretation of laws and regulatory commission orders.
If,  for  any reason, the Company ceases to meet the criteria for application of
regulatory  accounting  treatment  for  all  or  part  of  its  operations,  the
regulatory assets and liabilities related to those portions ceasing to meet such
criteria  would  be  eliminated  from  the  Consolidated Statements of Financial
Position  and  included  in  the  Consolidated  Statements of Operations for the
period  in  which  the discontinuance of regulatory accounting treatment occurs.
Such  amounts  would  be  classified  as  an  extraordinary  item.

GOODWILL.  The  Company evaluates its goodwill for impairment in accordance with
SFAS  142,  "Goodwill  and Other Intangible Assets."  SFAS 142 requires that the
Company perform impairment tests on its goodwill balance annually or at any time
when  events  occur  which  could  impact  the  value  of the Company's business
segments.  The  Company's determination of whether an impairment has occurred is
based  on  an  estimate  of  discounted cash flows attributable to the Company's
reporting  units  that have goodwill, as compared to the carrying value of those
reporting  units'  net  assets.  The  Company  must  make long-term forecasts of
future revenues, expenses and capital expenditures related to the reporting unit
in  order to make the estimate of discounted cash flows. These forecasts require
assumptions  about  future  demand,  future  market  conditions,  regulatory
developments  and  other factors. Significant and unanticipated changes to these
assumptions  could  require a provision for impairment in a future period. If an
impairment test of goodwill shows that the carrying amount of the goodwill is in
excess  of  the fair value, a corresponding impairment loss would be recorded in
the Consolidated Statements of Operations. The 2002 annual impairment tests were
performed  for  the  Company's business segments and indicated that there was no
impairment  of  goodwill.

PENSIONS  AND  OTHER  POSTRETIREMENT BENEFITS.  The Company accounts for pension
costs  and  other  postretirement  benefit costs in accordance with the SFAS 87,
"Employers'  Accounting  for  Pensions" and SFAS 106, "Employers' Accounting for
Postretirement  Benefits  Other  Than  Pensions," respectively. These Statements
require  liabilities  to be recorded in the Consolidated Statements of Financial
Position  at  the  present value of these future obligations to employees net of
any  plan  assets.  The calculation of these liabilities and associated expenses
require the expertise of actuaries and are subject to many assumptions including
life  expectancies,  present  value  discount  rates, expected long-term rate of
return on plan assets, rate of compensation increase and anticipated health care
costs.  Any  change  in these assumptions can significantly change the liability
and  associated  expenses  recognized  in  any  given  year.  For example, a one
percentage  point  increase  in  anticipated  health  care costs each year would
increase  the  accumulated retiree medical obligation as of December 31, 2002 by
$4.4  million  and  the aggregate of the service and interest cost components of
net  periodic  retiree  medical  costs  for  2002  by  $.4  million.


NEW  ACCOUNTING  STANDARDS

In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") 143, "Accounting for Asset Retirement
Obligations," which is effective January 1, 2003.  SFAS 143 requires entities to
record  the  fair value of a liability for an asset retirement obligation in the
period  in  which  it  is  incurred.
     When  the liability is initially recorded, the entity capitalizes a cost by
increasing  the carrying amount of the related long-lived asset.  Over time, the
liability is accreted to its present value each period, and the capitalized cost
is  depreciated  over  the useful life of the related asset.  Upon settlement of
the  liability,  an entity either settles the obligation for its recorded amount
or incurs a gain or loss upon settlement.  The Company does not believe that the
adoption  of SFAS 143 will have a material impact on its financial condition and
results  of  operation.
     In April 2002, the FASB issued SFAS 145, "Rescission of FASB Statements No.
4,  44  and  64, Amendment of FASB Statement No. 13, and Technical Corrections".
SFAS  145  eliminates  SFAS 4, Reporting Gains and Losses from Extinguishment of
Debt"  ("SFAS  4")  and  thus  allows  for  only  those  gains  or losses on the
extinguishment  of  debt  that  meet  the  criteria of extraordinary items to be
treated  as  such  in  the  financial statements.  SFAS 145 also amends SFAS 13,
Accounting  for  Leases"  ("SFAS  13")  to require sale-leaseback accounting for
certain  lease  modifications  that  have  economic  effects that are similar to
sale-leaseback  transactions.  The  provisions of this Statement relating to the
rescission  of  SFAS  4  are  effective for fiscal years beginning after May 15,
2002.  The provisions of this Statement relating to the amendment of SFAS 13 are
effective for transactions occurring after May 15, 2002. All other provisions of
this  Statement  are  effective  for  financial  statements  issued  on or after
May  15,  2002.
     In  June  2002,  the FASB issued SFAS 146, "Accounting for Costs Associated
with  Exit  or  Disposal  Activities".  SFAS 146 requires that the liability for
costs  associated  with exit or disposal activities be recognized when incurred,
rather than at the date of a commitment to an exit or disposal plan. SFAS 146 is
to  be  applied  prospectively  to  exit  or disposal activities initiated after
December  31,  2002.
     The  Company  has  evaluated  the  impact  of  SFAS 145 and SFAS 146 on its
financial  statements  and  does  not  expect  it  to  be  material.
     In November 2002, the FASB issued SFAS No. 148, "Accounting for stock-Based
Compensation  -  Transition  and  Disclosure- an amendment of FASB Statement No.
123." SFAS 148 amends SFAS No. 123 "Accounting for Stock-Based Compensation," to
provide  alternative  methods  of  transition for a voluntary change to the fair
value  method  of accounting for stock-based employee compensation. In addition,
SFAS 148 amends the disclosure requirements of SFAS No. 123 to require prominent
disclosures in both the annual and interim financial statements about the method
of accounting for stock-based employee compensation and the effect of the method
used on reported results. The disclosure requirements apply to all companies for
fiscal  years  ending after December 15, 2002. The interim disclosure provisions
are  effective for financial reports containing financial statements for interim
periods  beginning  after  December  15,  2002.  The adoption of SFAS 148 is not
expected  to  have  a  material  impact  on the Company's consolidated financial
statements.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

     In  November  2002,  the  FASB  issued  Interpretation No. 45, "Guarantor's
Accounting  and  Disclosure  Requirements  for  Guarantees,  Including  Indirect
Guarantees  of  Indebtedness  of  Others"  ("FIN  45"). FIN 45 elaborates on the
existing  disclosure requirements for most guarantees, including loan guarantees
and  standby  letters  of  credit.  It also clarifies that at the time a company
issues a guarantee, the company must recognize an initial liability for the fair
value,  or  market  value  of the obligations it assumes under the guarantee and
must  disclose  that information in its interim and annual financial statements.
The  provisions of FIN 45 related to recognizing a liability at inception of the
guarantee  do  not  apply  to  product warranties or guarantees accounted for as
derivatives.  The  initial recognition and initial measurement provisions of FIN
45  apply on a prospective basis to guarantees issued or modified after December
31,  2002.  The disclosure provisions are effective for financial statements for
periods  ending  after December 15, 2002. The Company believes that the adoption
of the recognition and measurement provisions of FIN 45 will not have a material
impact  on  its  financial  statements.
     In  January  2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable  Interest Entities an Interpretation of ARB No. 51" ("FIN 46").  FIN 46
is  not expected to have an impact on the Company's financial statements because
the  Company  does  not  have  any  variable  interest  entities.

REPORT  OF  INDEPENDENT  PUBLIC  ACCOUNTANTS

To  SEMCO  Energy,  Inc.:

In  our  opinion, the accompanying consolidated statements of financial position
and  capitalization  as  of  December  31,  2002  and  the  related consolidated
statements  of operations, changes in common shareholders' equity and cash flows
present  fairly,  in  all  material  respects,  the  financial position of SEMCO
Energy,  Inc.  and it subsidiaries at December 31, 2002 and the results of their
operations  and  their  cash  flows  for  the year then ended in conformity with
accounting principles generally accepted in the United States of America.  These
financial  statements  are  the  responsibility of the Company's management; our
responsibility  is  to express an opinion on these financial statements based on
our  audit.  We  conducted  our  audit  of  these  statements in accordance with
auditing  standards  generally  accepted  in the United States of America, which
require  that we plan and perform the audit to obtain reasonable assurance about
whether  the  financial  statements are free of material misstatement.  An audit
includes  examining,  on  a  test  basis,  evidence  supporting  the amounts and
disclosures  in  the  financial  statements, assessing the accounting principles
used  and  significant  estimates made by management, and evaluating the overall
financial  statement  presentation.  We  believe  that  our  audit  provides  a
reasonable basis for our opinion.  The financial statements of the Company as of
December 31, 2001 and for each of the two years in the period ended December 31,
2001, prior to the inclusion of the goodwill transitional disclosures in Note 1,
were  audited  by  other  independent  accountants  who  have ceased operations.
Those  independent  accountants  expressed  an  unqualified  opinion  on  those
financial  statements  in  their  report  dated  February  7,  2002.
     As  explained  in  Note 1 to the financial statements, effective January 1,
2002, SEMCO Energy, Inc. changed its method of accounting related to goodwill in
accordance  with the adoption of Statement of Financial Accounting Standards No.
142,  "Goodwill  and  Other  Intangible  Assets"
     As  discussed  above,  the financial statements of SEMCO Energy, Inc. as of
December  31,  2001,  and for each of the two years in the period ended December
31,  2001  were  audited  by  other  independent  accountants  who  have  ceased
operations. As described in Note 1, these financial statements have been revised
to  include  the  transitional  disclosures  required  by Statement of Financial
Accounting  Standards  No.  142.  We audited the adjustments in the transitional
disclosures  in Note 1. In our opinion, all such adjustments are appropriate and
have  been  properly  applied. However, we were not engaged to audit, review, or
apply  any  procedures  to the 2001 and 2000 financial statements of the Company
other  than with respect to such adjustments and, accordingly, we do not express
an  opinion  or  any  other  form  of  assurance  on the 2001 and 2000 financial
statements  taken  as  a  whole.

REPORT  OF  INDEPENDENT  PUBLIC  ACCOUNTANTS


The  following report is a copy of a report previously issued by Arthur Andersen

     As  discussed  in  Note 1, the Company has revised its Financial Statements
for  the  years  ended  December  31,  2001 and 2000 to include the transitional
disclosures  required  by  Statement  of Financial Accounting Standards No. 142,
Goodwill  and  Intangible  Assets.  The Andersen report does not extend to these
changes.  The  revisions  to  the  2001 and 2000 Financial Statements related to
these  transitional  disclosures were reported on by PricewaterhouseCoopers LLP,
as  stated  in  their  report  appearing  herein.


To  SEMCO  Energy,  Inc.

statements  of income, changes in common shareholders' equity and cash flows for
each  of  the three years in the period ended December 31, 2001. These financial
statements  are  the  responsibility  of  the  Company's  management.  Our

audits  provide  a  reasonable  basis  for  our  opinion.
     In  our  opinion,  the  consolidated financial statements referred to above
present  fairly,  in  all  material  respects,  the  financial position of SEMCO
Energy,  Inc. and subsidiaries as of December 31, 2001 and 2000, and the results

40 -- SEMCO ENERGY, INC. AND SUBSIDIARIES



NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


NOTE  1.  SIGNIFICANT  ACCOUNTING  POLICIES

Company  Description.  SEMCO  Energy,  Inc., is an investor-owned company. SEMCO
Energy,  Inc.  and  its  subsidiaries  (the  "Company")  operate four reportable
business  segments:  (1)  gas  distribution;  (2)  construction  services;  (3)
information  technology  services;  and  (4) propane, pipelines and storage. The
latter  three  segments  are  sometimes referred to together as the "Diversified
Businesses."  The  Company's  gas  distribution business segment distributes and
transports  natural  gas  to  approximately  272,000  customers  in the state of
Michigan  and  approximately  111,000  customers  in  the  state  of Alaska. The
Alaska-based  operation  and  the Michigan-based operation are known together as
the  "Gas  Distribution Business" and operate as divisions of SEMCO Energy, Inc.
     The  construction  services  segment  ("Construction  Services")  currently
conducts most of its business in the midwestern, southern and southeastern areas
of  the  United  States.  Its primary service is the installation and upgrade of
compressor  stations  and  underground  natural  gas  mains  and  service lines.
      The  information  technology  services  segment  ("IT  Services")  is
headquartered  in  Michigan  and provides IT infrastructure outsourcing services
and  other IT services with a focus on mid-range computers, particularly the IBM
I-Series  (AS-400) platform. The Company's other business segments accounted for
approximately  79%  of  IT  Services'  revenues  during  2002.
     The  propane,  pipelines  and  storage  segment  sells  more than 4 million
gallons  of  propane  annually to retail customers in Michigan's upper peninsula
and  northeast  Wisconsin  and  operates  natural  gas  transmission and storage
facilities  in  Michigan.
     The  Company  began  accounting  for  its engineering services segment as a
discontinued  operation,  effective  with  the  fourth  quarter  of  2001.  For
additional information, refer to the "Discontinued Operations" disclosure within
this  Note.

BASIS OF PRESENTATION.  The financial statements of the Company were prepared in
conformity  with  accounting principles generally accepted in the United States.
In  connection  with the preparation of the financial statements, management was
required  to  make estimates and assumptions that affect the reported amounts of
assets  and  liabilities  and disclosure of contingent assets and liabilities at
the  date  of  the financial statements and the reported amounts of revenues and
expenses  during  the  reporting  period. Actual results could differ from those
estimates.

PRINCIPLES  OF CONSOLIDATION.  The consolidated financial statements include the
accounts of SEMCO Energy, Inc. and its wholly-owned subsidiaries. Investments in
unconsolidated  companies  where the Company has significant influence, but does
not  control  the  entity,  are  reported using the equity method of accounting.
     Certain  of  the  Company's  diversified businesses, primarily Construction
Services and IT Services, supply services at a profit to the Company's regulated
gas  distribution business. In accordance with Statement of Financial Accounting
Standard  ("SFAS")  71,  "Accounting  for  the  Effects  of  Certain  Types  of
Regulation,"  intercompany  profits  remaining  in  the  assets of the regulated
business  at  a  particular  date  are not eliminated since it is probable that,
through  the  ratemaking  process,  the  cost  will  be recovered through future
revenue.  As  a  result,  $.1  million, $.6 million and $.9 million of profit on
revenues  earned  from  the  Company's  regulated  business  by  the  Company's
diversified  businesses  was  not eliminated during consolidation in 2002, 2001,
and 2000 respectively. All other significant intercompany transactions have been
eliminated.

RATE  REGULATION.  The  Gas  Distribution Business is subject to regulation. The
regulatory  matters  associated  with  gas distribution customers located in the
City  of  Battle Creek, Michigan, and surrounding communities are subject to the
jurisdiction  of  the  City  Commission  of  Battle Creek ("CCBC"). The Michigan
Public  Service Commission ("MPSC") has jurisdiction over the regulatory matters
related  to  the  Company's remaining Michigan customers. Regulatory matters for
gas  distribution  customers  in  Alaska  are subject to the jurisdiction of the
Regulatory  Commission  of  Alaska  ("RCA").  These  regulatory  bodies  have
jurisdiction  over,  among  other  things,  rates,  accounting  procedures,  and
standards of service. The Gas Distribution Business is subject to the provisions
of  SFAS  71.  Refer  to  Note  2  for additional information regarding SFAS 71.

RESTRICTED  CASH.  At  December  31,  2002,  the  Company  had  $1.2  million of
restricted  cash.  The  Company  expects this cash will be disbursed or that the
restricted  status  will  be  removed  within  one  year.

PROPERTY,  PLANT, EQUIPMENT AND DEPRECIATION.  The Company's property, plant and
equipment  ("property")  is  recorded  at  cost.  The  Company  provides  for
depreciation  on  a  straight-line  basis over the estimated useful lives of the
related  property.  The ratio of depreciation to the average balance of property
approximated  4.9%  for  the  year  2002  and  4.7% for the years 2001 and 2000.

41 -- SEMCO ENERGY, INC. AND SUBSIDIARIES




NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS

     On  January  1,  2002,  the  Company  adopted SFAS 144, "Accounting for the
Impairment  or  Disposal  of  Long-Lived  Assets,"  which  replaces  SFAS  121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be  Disposed  of" and Accounting Principles Board ("APB") Opinion 30, "Reporting
Results  of  Operations-Reporting  the  Effects  of  Disposal  of a Segment of a
Business,  and  Extraordinary,  Unusual  and  Infrequently  Occurring Events and
Transactions."
     SFAS  144  requires long-lived assets to be measured at the lower of either
the  carrying amount or the fair value less the cost to sell the assets, whether
reported  in  continuing  operations  or in discontinued operations.  Therefore,
discontinued  operations  will  no longer be measured at net realizable value or
include  amounts  for  operating  losses  that  have  not  yet  occurred.
     SFAS  144 also broadens the reporting of discontinued operations to include
all  components  of an entity with operations that can be distinguished from the
rest  of  the  entity and that will be eliminated from the ongoing operations of
the  entity  in  a disposal transaction. The adoption of SFAS 144 will result in
the  Company  accounting  for  any  future  impairment or disposal of long-lived
assets under the provisions of SFAS 144, but has not changed the accounting used
for  previous  asset  impairments  or  disposals.

GAS  IN UNDERGROUND STORAGE.  The gas inventory of the Gas Distribution Business
at  December 31, 2002 is reported at average cost. The gas inventory at December
31,  2001  was  also  stated at average cost with the exception of the inventory
held  by  the  Battle Creek division of the Gas Distribution Business, which was
stated  at  last-in,  first-out  ("LIFO")  cost.  At  December  31,  2001,  the
replacement  cost of the Battle Creek division's gas inventory exceeded the LIFO
cost  by  $0.2  million.
     During 2002, the Battle Creek Division changed its method of accounting for
gas inventory from LIFO to average cost. This change in accounting principle was
made  in  order  to provide a better matching of expenses with revenues and make
Battle  Creek's accounting for gas inventory consistent with the Company's other
gas  distribution  divisions and other Michigan gas distribution companies. This
accounting  change  was  not  material  to  the  financial  statements,  and,
accordingly, no retroactive restatement of prior years' financial statements was
made.
     In  general,  commodity  costs  and  variable  transportation  costs  are
capitalized  as  gas  in  underground  storage.  Fixed costs, primarily pipeline
demand  charges  and  storage  charges, are expensed as incurred through cost of
gas.

GOODWILL.  Goodwill  represents  the  excess of purchase price and related costs
over  the  value  assigned to the net tangible assets of businesses acquired. On
January  1, 2002, the Company adopted SFAS 141, "Business Combinations" and SFAS
142,  "Goodwill  and  Other  Intangible  Assets."  SFAS  141 addresses financial
accounting  and  reporting  for  all business combinations and requires that all
business combinations entered into subsequent to June 30, 2001 be recorded under
the  purchase  method.  This  Statement  also addresses financial accounting and
reporting  for  goodwill  and  other  intangible  assets  acquired in a business
combination  at  acquisition.  SFAS  142  addresses  financial  accounting  and
reporting  for  intangible assets acquired individually or with a group of other
assets  at  acquisition.  This Statement also addresses financial accounting and
reporting  for  goodwill  and  other  intangible  assets  subsequent  to  their
acquisition.
     In compliance with SFAS 142, goodwill amortization ceased effective January
1,  2002.  Prior  to  January  1,  2002,  goodwill  was  being  amortized  on  a
straight-line  basis  over  periods  of up to 40 years. Amortization expense was
approximately  $4.6  in  2001 and $4.0 million in 2000. During 2001, the Company
recorded a charge of $4.0 million for the impairment of goodwill associated with
the  Company's  construction  services  segment and its discontinued engineering
services  business.  The  Company's carrying amount for goodwill at December 31,
2002 was $161.1 million, of which $140.2 million related to the Gas Distribution
Business,  $17.7  million related to Construction Services, $3.1 million related
to  the  Propane,  Pipelines  and  Storage segment and $.1 million related to IT
Services.
     The  Company  was  required to complete a transition impairment test in the
year  of  adoption  of  SFAS  142 and perform subsequent impairment tests on the
remaining goodwill balance annually or at any time when events occur which could
impact  the  value  of the Company's business segments. If an impairment test of
goodwill shows that the carrying amount of the goodwill is in excess of the fair
value,  a  corresponding  impairment  loss would be recorded in the Consolidated
Statements of Operations. The transition impairment tests were performed for the
Company's  business  units  and  the  results  of  those  tests indicate that no
impairment of the Company's goodwill balances existed as of January 1, 2002. The
2002  annual  impairment  tests  were  also performed for the Company's business
segments  and  indicated that there was no impairment of goodwill.  As a result,
there was no change in the carrying amount of goodwill at December 31, 2002 when
compared  to  December  31,  2001.
     The  following  table  presents what would have been reported as net income
(loss)  available  to common shareholders and the related per share amounts on a
basic  and  diluted  basis  in  2002,  2001, and 2000, exclusive of amortization
expense  (including  any  related  tax  effects)  related  to  goodwill.

LONG-TERM  NOTE RECEIVABLE.  The Company sold its entire interest in an Arkansas
pipeline to ENOGEX Arkansas Pipeline Corporation ("ENOGEX") in 1998. Pursuant to
the  terms  included  in  the  sales  agreement, the Company will receive annual
payments  of $.8 million from ENOGEX for 17 years beginning in the year 2004. At
December  31,  2002,  the  Company has a long-term discounted note receivable of
$7.7  million  for  this  note,  which is reported in deferred charges and other
assets  in  the  Consolidated  Statements  of  Financial  Position.

REVENUE  RECOGNITION.  The  Gas  Distribution  Business bills monthly on a cycle
basis  and  follows the industry practice of recognizing accrued revenue for gas
services  rendered  to  its  customers but not billed at month end. Construction
Services  recognizes  revenues  as  services  are  rendered.  In  instances when
projects  are long-term, Construction Services uses the percentage of completion
method.  At  December  31,  2002,  Construction  Services  did  not  have  any
significant long-term projects. The propane business recognizes propane sales in
the  same  period  that  the  propane  is  delivered  to  customers.

COST  OF  GAS.  The  Alaska-based  gas  distribution  operation ("ENSTAR") has a
regulator-approved  gas  cost adjustment ("GCA") pricing mechanism, which allows
for  the  adjustment  of  rates charged to customers in Alaska for increases and
decreases in the cost of gas purchased. Under the GCA pricing mechanism, the gas
charge  portion  of  customers'  gas  rates  is adjusted annually to reflect the
estimated cost of gas purchased for the upcoming 12-month period. Any difference
between  actual  cost of gas purchased and the estimate is deferred as a current
asset or current liability and included in the next annual adjustment to the gas
charge  portion  of rates. The GCA may be adjusted quarterly if it is determined
that  there  are  significant  variances  from  the estimates used in the annual
determination.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


     ENSTAR  has RCA approved gas purchase contracts with several entities.  The
base price of gas purchased under these contracts can be adjusted annually based
on  factors such as the price of certain traded oil futures, certain natural gas
futures  and  other  inflationary  measures.  Under  the  GCA pricing mechanism,
customers  in  Alaska  are  charged amounts that allow the Company to recoup its
cost of purchased gas.  As a result, the Company does not earn any income on the
gas  charge  portion  of  ENSTAR's  rates.
     Prior  to  April  1,  1999,  the  Company's Michigan-based gas distribution
operation  had  a regulator-approved gas cost recovery ("GCR") pricing mechanism
for  the geographic areas subject to the regulatory jurisdiction of the MPSC and
CCBC.  The  GCR  pricing mechanism works similarly to the GCA pricing mechanism.
During  the three-year period from April 1, 1999 to March 31, 2002, the MPSC and
CCBC authorized the Company to suspend its GCR clause and freeze in its customer
base  rate  a  fixed  gas  charge  of $3.24 per thousand cubic feet ("Mcf"). The
Company was able to offer this Michigan GCR suspension and rate freeze mainly as
a  result  of  agreements  reached  with  TransCanada  Gas  Services,  Inc.
("TransCanada"),  which also covered the three-year period from April 1, 1999 to
March  31,  2002.  During  2001, TransCanada sold its gas marketing business and
assigned  the  agreements  to BP Canada Energy Marketing Corp. (formerly "BP Gas
and  Power")  , with the Company's consent. Under the agreements, TransCanada or
BP  Canada  Energy  Marketing  Corp ("BP") provided a significant portion of the
Company's natural gas requirements, and managed the Company's natural gas supply
and  the supply aspects of transportation and storage operations in Michigan for
the  three-year  period,  at a cost that was, in most instances, below the $3.24
price charged to customers. As a result, during the three-year period from April
1, 1999 through March 31, 2002, the Michigan gas distribution operation retained
any  gas  costs savings that resulted when the cost of purchased natural gas was
below  the  $3.24 fixed price charged to customers, subject to a customer profit
sharing  mechanism  described  in  Note  2.
     When  the  suspension period for the GCR pricing mechanism expired on March
31, 2002, the Company reinstated its GCR pricing mechanism for customers subject
to  the  jurisdiction  of  the  MPSC ("MPSC customers"). Consequently, effective
April  1,  2002,  the  Company could no longer earn any income on the gas charge
portion of MPSC customers' rates. The Company received approval from the CCBC to
extend  the GCR suspension period and fixed gas charge program, with a new fixed
gas  charge,  until  March  31,  2005  for customers subject to its jurisdiction
("CCBC  customers").
     The  Company  has  entered  into new agreements with BP for the natural gas
supply  requirements  of the CCBC customers, supply portfolio management for the
MPSC  customers,  and  transportation  and storage asset management for both the
CCBC  and  MPSC  customers.
     Under  the  new BP agreement covering MPSC customers, the Company no longer
purchases  gas  at  a  fixed  cost  over  a number of years. In keeping with the
Company's  switch  back  to  the  GCR  pricing mechanism for MPSC customers, the
Company  is  required  to solicit bids for all supplies with term lengths longer
than  three days. Supplies with term lengths of three days or less are purchased
from  BP.  The  new BP agreement covering CCBC customers will continue to have a
fixed  cost  for the purchase of natural gas and is effective for the three-year
period  from  April  1,  2002  through  March  31,  2005.
     In  accordance with the GCR pricing mechanism, the Company had $2.2 million
recorded in current assets at December 31, 2002 for gas charges recoverable from
customers.  Also  at December 31, 2002, the Company had $1.1 million recorded in
current  liabilities for amounts payable to customers in accordance with the GCA
pricing  mechanism.

INCOME TAXES.  Investment tax credits ("ITC") utilized in prior years for income
tax  purposes  are  deferred for financial accounting purposes and are amortized
through  credits  to  the  income  tax  provision  over the lives of the related
property.  The Company files a consolidated federal income tax return and income
taxes are allocated among the subsidiaries within each business segment based on
their  separate  taxable  income.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


DISCONTINUED  OPERATIONS.  In  December  2001,  the Company's board of directors
approved  a plan to redirect the Company's business strategy, which included the
divestiture  of  its  engineering  services business. As a result, the operating
results  and loss on disposal of this business have been segregated and reported
as discontinued operations in the Consolidated Statements of Operations.  A loss
of  approximately  $5.0  million,  representing  the  estimated  loss during the
phase-out  period  and  the  estimated  loss  on  disposal,  was  reported  as
discontinued  operations  in  the 2001 Consolidated Statement of Operations. The
Company sold its engineering services business effective November 1, 2002. There
was a difference of $10 thousand between the actual losses and estimated losses,
which  is  reported  as  discontinued  operations  in  2002.  For  additional
information, refer to Note 14 of the Notes to Consolidated Financial Statements.

NOTE  2.  REGULATORY  MATTERS

RCA.  The Company's Alaska gas distribution division, ENSTAR Natural Gas Company
and  its  subsidiary, Alaska Pipeline Company (together known as "ENSTAR"), have
been  undergoing  a  rate  review  with  the  RCA  since  2000.
     The  Company  received  an  Order  dated August 8, 2002 from the RCA on its
review  of  rates  for ENSTAR based on normalized data for the year 2000. In its
Order  the  RCA established a revenue requirement of $107.6 million and a 12.55%
return  on  equity.  In  response  to  a  petition  by ENSTAR, the RCA issued an
additional  Order  dated  September  16, 2002 which revised the indicated annual
revenue reduction from $2.1 million to $2.0 million, which was 1.84% of ENSTAR's
revenue in the normalized 2000 test year. The Order required ENSTAR to implement
the  rate  reduction by September 27, 2002 on an across-the-board basis. The RCA
also  required  ENSTAR  to file an updated cost of service study by September 9,
2002  and  a  rate  design  in  December 2002, with a hearing on the rate design
filing  scheduled  for  May  2003. ENSTAR has implemented the rate reduction and
filed  both the cost of service study and the rate design as required.  The rate
design  filed with the RCA by ENSTAR requests greater recovery of fixed costs in
the  monthly  customer charge and declining block rates for gas sales customers.

MPSC  AND  CCBC.  During  the  three-year period from April 1, 1999 to March 31,
2002, the division of the Gas Distribution Business, subject to the jurisdiction
of  the  MPSC, was under an MPSC order which, among other things, authorized the
Company  to: (1) suspend its GCR clause; (2) freeze in its customer base rate, a
fixed  gas charge of $3.24 per Mcf; (3) freeze distribution rate adjustments and
(4)  adopt a new income sharing mechanism for use during the 1999, 2000 and 2001
calendar  years.
     The  MPSC  order was applicable only in the geographic areas subject to the
regulatory  jurisdiction  of  the  MPSC,  and,  therefore,  did not govern rates
regulated  by  the  CCBC.  However,  the  Gas  Distribution Business voluntarily
requested,  and  the  CCBC approved, a similar freeze in the gas charge at $3.24
for customers subject to the jurisdiction of the CCBC. The CCBC also approved  a
suspension  of  the GCR clause, a distribution rate freeze and an income sharing
mechanism  similar  to the MPSC approved program. The changes were effective for
the  same  time  period  as  the  changes  approved  by  the  MPSC.

45 -- SEMCO ENERGY, INC. AND SUBSIDIARIES



NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


     Several  of  the  items in the MPSC order were interrelated.  The fixed gas
charge  and the suspension of the GCR clause meant that customers paid $3.24 per
Mcf  regardless  of  the  Company's  actual  cost  of  gas. The Gas Distribution
Business  was  able to offer this Michigan GCR suspension and rate freeze mainly
as  a  result  of  agreements reached with TransCanada. Refer to the Cost of Gas
section of Note 1 for further information about the GCR clause, fixed gas charge
and  TransCanada  agreements.
     The  profit  incentive and sharing mechanism was effective for the calendar
years  1999,  2000  and  2001.  Under  the mechanism, if the Company's return on
equity for its Michigan-based natural gas distribution business exceeded 12.75%,
certain  portions  of  the  excess  return would be credited to customers, i.e.,
would  be  reflected prospectively in reduced rates. Four safety and reliability
performance  measures  were required to be met in order not to reduce the return
on  equity  threshold  used  in  the  income  sharing  mechanism.
     The  Company  received  approval from the CCBC to extend the GCR suspension
period  and  the  fixed  gas  charge program, with a new fixed gas charge, until
March  31,  2005 for CCBC customers.  The profit incentive and sharing mechanism
discussed  previously  will  remain  in  effect  through  March  2005  for  CCBC
customers. The Company also received approval during 2001 from the CCBC to start
charging  CCBC  customers on a thermal basis rather than a volumetric basis. The
Company buys all its natural gas by the dekatherm and now also sells it to these
customers  by  the  dekatherm.
     The  Company  filed an application with the MPSC in late 2001 to extend its
fixed  charge program until March 31, 2005 and increase the current fixed charge
for  MPSC  customers. However, the Company was unable to reach an agreement with
the MPSC and other interested parties on a fixed customer charge for natural gas
for  the  three  years of the proposed extended period. As a result, the Company
reinstated  its  GCR pricing mechanism when the fixed gas charge program expired
on  March  31,  2002. Refer to the Cost of Gas section of Note 1 for information
regarding  the  GCR  pricing  mechanism.
     Beginning  in  2002,  the  profit incentive and sharing mechanism discussed
previously  is  no  longer  in  effect  for  MPSC customers. Instead, the profit
incentive  and  sharing  mechanism  in  effect  for  the  calendar year 1998 was
reinstated  for  2002.  Under  this  mechanism,  referred  to as a reverse taper
incentive,  if the return on equity for the division of Company's Michigan-based
natural gas distribution business that serves its MPSC customers exceeds 10.75%,
certain portions of the excess return between 10.75% and 16.0% would be credited
to  customers.  For  purposes of this mechanism, if the return on equity exceeds
16.0%,  the  Company  is required to file a general rate case with the MPSC. The
return  on  equity  did  not  exceed  10.75%  for  2002.
     On  November  21,  2002  the  MPSC  regulated  division of SEMCO Energy Gas
Company  filed  an  application  for  a  general rate increase of $10.9 million.
Among  the  principal reasons for the requested increase were higher pension and
healthcare costs and investment of approximately $120 million in new plant since
the  last  rate case was approved in 1997.  In addition to specific rate relief,
the  application  sought an innovative rate design, which would mitigate some of
the  effects  of warmer than normal weather on the Company's earnings.  This new
rate  design  calls  for greater recovery of fixed costs in the monthly customer
charge  and  declining  block  rates for gas sales customers. This would provide
more stability in customer bills by moving costs from the peak heating season to
summer  and  off-peak  heating  months.  The  filing  also  requests a change to
customer  billing  based  on  the heat content of natural gas, or therms, rather
than  the current volumetric measure, cubic feet.  An order is expected in 2003.

REGULATORY  ASSETS AND LIABILITIES.  The Gas Distribution Business is subject to
the  provisions  of  SFAS  71,  "Accounting  for the Effects of Certain Types of
Regulation."  As  a  result,  the actions of regulators affect when revenues and
expenses  are  recognized.  Regulatory  assets  represent  incurred  costs to be
recovered  from customers through the ratemaking process. Regulatory liabilities
represent  benefits  to  be  refunded  to  customers.
     In  the  event the Company determines that the Gas Distribution Business no
longer  meets the criteria for following SFAS 71, the accounting impact would be
an  extraordinary,  non-cash  charge  to  operations  of an amount that could be
material.  Criteria  that give rise to the discontinuance of SFAS 71 include (1)
increasing  competition  that  restricts  the  ability  of  the Gas Distribution
Business  to  establish  prices to recover specific costs, and (2) a significant
change  in  the  manner  in  which  rates  are set by regulators from cost-based
regulation to another form of regulation. The Company's periodic review of these
criteria  currently  supports  the  continuing  application  of  SFAS  71.

DEFERRED  INCOME  TAXES.  Deferred income taxes arise from temporary differences
between  the  tax  bases of assets and liabilities and their reported amounts in
the  financial statements. At December 31, 2002, there was a valuation allowance
of  $.6  million  recorded  against deferred tax assets. The valuation allowance
relates to a capital loss incurred in 2002 that is likely to expire before being
realized for tax purposes. At December 31, 2001 there was no valuation allowance
recorded against deferred tax assets. The Company has an estimated net operating
loss  ("NOL") carryforward for federal tax purposes of $35.6 million at December
31,  2002,  of  which $21.0 million expires in 2021 and $14.6 million expires in
2022.  The  table below shows the principal components of the Company's deferred
tax  assets  (liabilities).

NOTE  4.  CAPITALIZATION

COMMON  STOCK EQUITY.  During 2002 and the last half of 2001, the Company issued
approximately  372,000  shares  and  166,000  shares, respectively of its common
stock  to  the  Company's  Direct  Stock Purchase and Dividend Reinvestment Plan
("DRIP")  to  meet  the dividend reinvestment and stock purchase requirements of
its  participants.  During  2000  and the first half of 2001, the DRIP purchased
Company  common  stock  on  the  open  market  to  meet  these  requirements.
     The  Company  issued  approximately  70,000,  19,000  and  52,000 shares of
Company common stock to certain of the Company's employee benefit plans in 2002,
2001  and  2000,  respectively. Also during 2002 and 2001, the Company purchased
approximately 40,000 shares and 48,000 shares, respectively, of its common stock
on  the  open market to contribute to certain of its employee benefit plans. The
Company  issued  83,000  shares  of  its  common  stock to the shareholders of a
business  acquired  during  2000.

COMPANY-OBLIGATED  MANDATORILY  REDEEMABLE  TRUST  PREFERRED  SECURITIES  OF
SUBSIDIARIES.  The  Company's  Capital  Trusts  were  established  for  the sole
purpose  of issuing trust preferred securities and lending the gross proceeds to
the  Company.  The  sole assets of the Capital Trusts are debt securities of the
Company  with  terms  similar  to  the  terms  of  the  related  trust preferred
securities.  The  Capital  Trusts  are  subsidiaries  of  the  Company.
     In  April  2000,  SEMCO Capital Trust I issued 1.6 million shares of 10.25%
cumulative  trust  preferred securities ("10.25% TPS") in a public offering at a
price  of  $25  per  security.  SEMCO  Capital  Trust  I used the $40 million in
proceeds  from  the  issuance  of  the  10.25%  TPS  to  invest  in subordinated
debentures of the Company bearing an interest rate of 10.25%. The 10.25% TPS are
subject to mandatory redemption upon repayment of the subordinated debentures at
maturity  or  their  earlier  redemption.  The subordinated debentures mature in
2040,  but  may  be  redeemed  at  any time after April 19, 2005, or at any time
within  90  days following the occurrence of certain special events. The Company
used  the  entire  net  proceeds from the sale of the subordinated debentures to
repay  a  portion  of  the  bridge  loan  utilized  in  the  ENSTAR acquisition.
      Also  during  2000,  the  Company  issued  10.1 million FELINE PRIDES in a
public offering at a price of $10 per security. Each FELINE PRIDES consists of a
stock  purchase  contract  of  the  Company and a 9% trust preferred security of
SEMCO  Capital  Trust  II  due 2005 with a stated face value per security of $10
("9%  TPS").  SEMCO Capital Trust II used the $101 million in proceeds to invest
in  9% senior deferrable notes of the Company due 2005. The Company used the net
proceeds  from the sale of the senior deferrable notes to repay a portion of the
bridge loan utilized for the acquisition of ENSTAR and to repay a portion of its
short-term  lines  of  credit.
     Under  the terms of each stock purchase contract (which is a component of a
FELINE  PRIDES unit), the FELINE PRIDES holder is obligated to purchase, and the
Company  is  obligated to sell, between .7794 and .8651 shares of Company common
stock  in  August  2003.  The actual number of shares of common stock to be sold
will  depend  on  the  average market value of a share of common stock in August
2003.  In  addition  to payments on the 9% TPS, the Company is also obligated to
pay  the  FELINE  PRIDES holders a quarterly contract adjustment payment on each
stock purchase contract at an annual rate of 2% of $10. The present value of the
contract  adjustment  payments, or $5.6 million, was recorded as a liability and
as  a  reduction  to  common  stock  capital surplus when the FELINE PRIDES were
issued.  As  the  Company  pays  the  contract adjustment payments, common stock
capital  surplus  is  also reduced by the interest component of the payments. In
addition,  common  stock  capital  surplus  was  reduced by $4.6 million for the
issuance  costs  of  the  FELINE  PRIDES.
     The  FELINE  PRIDES holders can settle their obligation to purchase Company
common stock by paying cash or by having their 9% TPS remarketed in August 2003.
The distribution rate on the 9% TPS will also be reset in August 2003. The reset
rate  will  be equal to the sum of the reset spread and the rate on the two-year
benchmark treasury and will be determined by the reset agent as the rate the TPS
should  bear  in  order  to  have  an approximate market value of 100.5% of $10.
However,  the  Company may limit the reset rate to be no higher than the rate on
the  two-year  benchmark  treasury  plus  200  basis  points  (or  2%).
     In  the  case  of  FELINE  PRIDES  holders  who decide to have their 9% TPS
remarketed,  $10 of the proceeds from remarketing each 9% TPS will automatically
be  applied  to  satisfy in full the obligation to purchase Company common stock
under  the  related stock purchase contract.  If the remarketing agent is unable
to  remarket  the  9% TPS at the reset rate, as described above, the Company may
exercise  its  right  as  a secured party to dispose of the 9% TPS in accordance
with  the  provisions  of the FELINE PRIDES, in order to satisfy any unfulfilled
obligation  to  purchase common stock under the related stock purchase contract.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


LONG-TERM  DEBT.  In August 2002, the Company issued $30 million of 6.49% Senior
Notes  due  2009  ("2009  Senior  Notes").  Interest on the 2009 Senior Notes is
payable semiannually. The proceeds from the sale were used to redeem $30 million
of  6.83%  Senior  Notes,  which  matured  on  October  1,  2002.
     In  June  2001,  the Company issued $60 million of 8% Senior Notes due 2016
("2016  Senior  Notes"). Interest on the 2016 Senior Notes is payable quarterly.
On or after June 30, 2006, the Company may redeem some or all of the 2016 Senior
Notes at a redemption price of 100% of the principal amount plus any accrued and
unpaid interest.  The 2016 Senior Notes contain provisions that give the estates
or  heirs  of  deceased  2016  Senior Note holders the right to request that the
Company  redeem  their 2016 Senior Notes. During 2002, the Company redeemed $110
thousand  of 2016 Senior Notes in accordance with these provisions. The proceeds
from  the  sale  of the 2016 Senior Notes were used to repay short-term debt and
for  general  corporate  purposes.
     In  August  2001,  the Company entered into an interest rate swap agreement
with a financial institution in order to hedge its $55 million 8% Notes due June
1,  2004.  The  swap  agreement,  which  covered  the  Notes  through  maturity,
effectively  converted  the  fixed  rate  on  the  Notes  to  a floating rate of
interest.  Under  the  terms  of  the  swap  agreement,  the  Company  paid  the
counterparty  a  floating  rate  of interest based on LIBOR plus a spread of 297
basis points and received payments based on a fixed rate of 8%. During 2002, the
Company terminated the interest rate swap and received $2.2 million. This amount
is  being  recognized  pro-rata  in  the  Company's  Consolidated  Statements of
Operations,  as  a reduction in interest expense, over the remaining term of the
$55  million  8%  Notes.
     In  April  2000,  the  Company sold $30 million of 8% Senior Notes due 2010
("2010 Senior Notes") in a public offering. Interest on the 2010 Senior Notes is
paid  semi-annually.  The  2010  Senior  Notes  contain provisions that give the
estates  or heirs of deceased 2010 Senior Note holders the right to request that
the  Company  redeem  their  2010  Senior Notes. During 2002, 2001 and 2000, the
Company  redeemed  $15  thousand, 10 thousand and $50 thousand, respectively, of
2010  Senior  Notes  in  accordance  with  these  provisions.
     The  Company  also  sold  $105  million of 8.95% Remarketable or Redeemable
Securities ("ROARS") in a public offering in June 2000. The ROARS were issued at
a  discount  of  approximately  $.3  million.  Interest  on the ROARS is payable
semi-annually. The ROARS mature in July 2008; however, the Company may purchase,
or  be  required  to  purchase,  all  of  the ROARS in July 2003 if they are not
remarketed as discussed below. The Company used the entire net proceeds from the
sale  of  the  2010 Senior Notes and ROARS to repay a portion of the bridge loan
utilized  for  the  acquisition  of  ENSTAR.
     In  conjunction  with  the  sale  of  the ROARS, the Company entered into a
remarketing  agreement  with  Banc of America Securities LLC ("BAS") under which
BAS  has  the  option  to  purchase  all  the ROARS in July 2003, at 100% of the
aggregate  principal amount of the ROARS. The Company received an option premium
of approximately $2.5 million for the remarketing option, which is included with
the  ROARS  in  long-term  debt  in  the  Company's  Consolidated  Statements of
Financial  Position.  The  option  premium is being amortized to income over the
life  of  the  ROARS.
     If  BAS elects to purchase the ROARS in July 2003, and the Company does not
exercise  its right to elect a floating interest rate or its right to redeem the
ROARS,  both  of which are discussed below, BAS will remarket the ROARS at a new
interest  rate.  The  new  fixed interest rate would be equal to the sum of 6.5%
(the  "Base  Rate")  and an applicable spread. Under the terms of the ROARS, the
applicable  spread  is  defined  as  the lowest bid received by BAS from various
leading  dealers of publicly traded debt securities, expressed as a spread above
the  Base  Rate  and  based on a purchase price equal to the Dollar Price of the
ROARS.  The  Dollar  Price  of the ROARS is defined as the present value, at the
remarketing  date in July 2003, of the remaining scheduled payments of principal
and  interest  through  maturity  in  July  2008  calculated  at  the Base Rate,
discounted  to the remarketing date in July 2003 using the rate on U.S. treasury
securities  with  maturities  comparable  to  the  remaining  term of the ROARS.
     If BAS elects to purchase the ROARS in July 2003, the Company will have the
right  to elect that BAS remarket the ROARS for a period of up to one year using
a floating interest rate ("Floating Rate Period") rather than the fixed interest
rate  described above.  At the end of the Floating Rate Period, BAS can elect to
purchase  the ROARS to remarket at a new fixed interest rate as described above.
     If  BAS elects to purchase the ROARS for remarketing in July 2003 or at the
end  of the Floating Rate Period, the Company will also have the right to redeem
the ROARS directly from BAS at either time at the Dollar Price as defined above.
If  BAS  does  not  elect  to  purchase  the  ROARS in July 2003, the Company is
required  to  redeem  all  of  the  ROARS  at that time at 100% of the aggregate
principal  amount  of the ROARS. If BAS does not exercise its option to purchase
the  ROARS  at  the  end of the floating rate period, the Company is required to
redeem  all  of  the  ROARS  at  that  time  at  the  Dollar  Price.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


     The  Company's long-term and short-term debt agreements contain restrictive
financial  covenants  including,  among  others,  maintaining  a  Fixed  Charges
Coverage  Ratio  (as  defined  in  the  agreements) of at least 1.50 and placing
limits  on  the  payment of dividends beyond certain levels. Non-compliance with
these  covenants  could  result in an acceleration of the due dates for the debt
obligations  under  the  agreements.  As of December 31, 2002, the fixed charges
coverage  ratio  was  1.89  and  the  Company  was in compliance with all of the
covenants  in  these  agreements.
     There  are  no  annual sinking fund requirements for the Company's existing
debt  over  the next five years. Debt maturing over the next five years includes
the  maturity  of  $55  million  of  8.0%  notes  in  2004,  $15 million of 6.5%
medium-term notes in 2005 and $30 million of 7.2% notes in 2007. The Company may
also  purchase,  or  be  required to purchase, the $105 million of ROARS in July
2003,  or  during  the  subsequent twelve months, if they are not remarketed, as
discussed  previously.  In  addition,  if  the  $101  million  of  9%  TPS  are
successfully  remarketed  in  2003,  they  will  mature  in  2005.


NOTE  5.  SHORT-TERM  BORROWINGS

During  2002,  the  Company  entered into a $145 million credit agreement with a
group of banks, replacing four lines of credit totaling $145 million, which were
due  to expire. The new agreement, all of which is committed, consists of an $80
million  three-year revolver and a $65 million 364-day facility, with a one-year
term  loan  option.  The  outstanding  balances  owed by the Company under these
credit  facilities  at  December  31,  2002,  2001 and 2000 were $121.2 million,
$105.5  million,  and  $133.4  million,  respectively.  Interest on these credit
facilites  is  at  variable  rates, which do not exceed the banks' prime lending
rates.

NOTE  6.  FINANCIAL  INSTRUMENTS

The  following  methods  and assumptions were used to estimate the fair value of
each  significant  class  of  financial  instruments:

CASH,  TEMPORARY  CASH  INVESTMENTS,  ACCOUNTS  RECEIVABLES,  PAYABLES AND NOTES
PAYABLE.  The  carrying  amount  approximates  fair  value  because of the short
maturity  of  those  instruments.

LONG-TERM  DEBT.  The  fair values of the Company's long-term debt are estimated
based on quoted market prices for the same or similar issues or, where no market
quotes  are  available,  based  on  discounted  future  cash flows using current
interest  rates  at  which similar loans would be made to borrowers with similar
credit  ratings and remaining maturities. Although the current fair value of the
long-term  debt  may  differ from the current carrying amount, settlement of the
reported  debt  is  generally  not  expected  until  maturity, with the possible
exception of the ROARS which could be redeemed in July 2003 as discussed in Note
4.

NOTE  7.  RISK  MANAGEMENT  ACTIVITIES  AND  DERIVATIVE  TRANSACTIONS

     The  Company's  business  activities  expose  it  to  a  variety  of risks,
including  commodity price risk and interest rate risk. The Company's management
identifies  risks  associated  with  the Company's business and determines which
risks  it  wants to manage and which type of instruments it should use to manage
those  risks.
      The  Company  records  any derivative instruments it enters into under the
provisions  of  SFAS  133,  "Accounting  for  Derivative Instruments and Hedging
Activities,"  and  SFAS  137  and  SFAS  138,  which were amendments to SFAS 133
(hereinafter  collectively  referred  to  as "SFAS 133"). SFAS 133 requires that
every  derivative  instrument (including certain derivative instruments embedded
in  other  contracts)  be  recorded  in  the Consolidated Statement of Financial
Position  as  either  an asset or liability measured at its fair value. SFAS 133
also  requires  that  changes  in  the  derivative's  fair  value  be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting  for  qualifying  hedges  allows  a  derivative's gains and losses to
offset  related results on the hedged item in the income statement, and requires
that  a  company must formally document, designate, and assess the effectiveness
of  transactions  that  receive  hedge  accounting.
     The  Company will, from time to time, enter into fixed to floating interest
rate  swaps in order to maintain its desired mix of fixed-rate and floating-rate
debt. These swaps are designated as fair value hedges and the difference between
the  amounts paid and received under these swaps is recorded as an adjustment to
interest  expense  over  the  term  of  the  swap  agreement.  If  the swaps are
terminated,  any  unrealized  gains  or  losses are recognized pro-rata over the
remaining  term  of  the  hedged  item  as  an  increase or decrease in interest
expense.  The Company entered into one such interest rate swap in August 2001 in
order  to hedge the Company's $55 million of 8% Notes due in June 2004. The swap
was  terminated  in  August 2002 and the Company received $2.2 million, which is
being  recognized  pro-rata,  as  a  reduction  in  interest  expense,  over the
remaining  term  of  the  Notes.  In  accordance  with  SFAS  133, the Company's
Consolidated  Statement of Financial Position, at December 31, 2001, included an
asset of $1.9 million and an increase in long-term debt of $1.9 million for this
interest  rate  swap.
     An affiliate, in which the Company has a 50% investment, uses a floating to
fixed  interest rate swap agreement to hedge the variable interest rate payments
on a portion of its long-term debt. This swap is designated as a cash flow hedge
and  the  difference  between  the  amounts  paid and received under the swap is
recorded  as  an  adjustment to interest expense over the term of the agreement.
The  Company's  share  of  changes in the fair value of the swap are recorded in
accumulated other comprehensive income until the swap is terminated. As a result
of  this  interest rate swap agreement, the Company's Consolidated Statements of
Financial  Position, at December 31, 2002 and December 31, 2001, reflected a $.7
million  reduction  in  the  Company's equity investment in the affiliate and in
accumulated  other  comprehensive  income.


NOTE  8.  PENSION  PLANS  AND  OTHER  POSTRETIREMENT  BENEFITS

PENSIONS.  The  Company  has  defined  benefit  pension  plans  that  cover  the
employees  of certain companies in the consolidated group. Pension plan benefits
are  generally  based upon years of service or a combination of years of service
and  compensation  during  the  final years of employment. The Company's funding
policy  is  to contribute amounts annually to the plans based upon actuarial and
economic  assumptions  designed to achieve adequate funding of projected benefit
obligations.  The  Company  also  has  a  supplemental executive retirement plan
("SERP"),  which  is  an  unfunded  defined  benefit  pension  plan.

- ----------
52 -- SEMCO ENERGY, INC. AND SUBSIDIARIES



NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


     During  2000, certain pension plans covering employees at the Company's gas
distribution  operations  and  corporate  offices  in  Michigan  and Alaska were
amended.  The  amendments  to  certain  of  the  plans included a special frozen
benefit  for certain eligible employees. In conjunction with the amendments, the
Company  offered  early  retirement  programs to certain eligible employees. The
programs  gave  the employees the options of receiving either a lump-sum pension
benefit  payment  or an immediate annuity. Sixty-three employees elected to take
the  early  retirement  offer. As a result of the 2000 early retirement program,
the  Company  incurred  a one-time gain, which reduced 2000 net periodic pension
costs  by  approximately  $.4  million.
     Because  of  unfavorable  returns on pension plan assets in 2001 and  2002,
certain  pension  plans  were  underfunded  at  December 31, 2002 and 2001. As a
result, a minimum pension liability of $3.0 million was recorded during 2001 and
an  additional  minimum  pension liability of $8.3 million was recorded in 2002.
The  total  minimum  pension  liability  at December 31, 2002 was $11.3 million.

OTHER  POSTRETIREMENT  BENEFITS.  The  Company  has postretirement benefit plans
that provide certain medical and prescription drug benefits to qualified retired
employees,  their  spouses  and covered dependents. Determination of benefits is
based  on a combination of the retiree's age and years of service at retirement.
The  Company  accounts for retiree medical benefits in accordance with SFAS 106,
"Employers'  Accounting  for  Postretirement Benefits Other Than Pensions." This
standard  requires  the  full  accrual  of  such costs during the years that the
employee  renders  service  to  the  Company until the date of full eligibility.
     In  2002, 2001 and 2000, the Company expensed retiree medical costs of $2.0
million,  $1.9  million  and  $1.5  million,  respectively.  The retiree medical
expense  for  each  of  those  years  includes  $0.9  million of amortization of
previously  deferred retiree medical costs. Prior to getting regulatory approval
for  the  recovery  of  retiree  medical  benefits  in  rates,  the Michigan gas
distribution  operation  deferred, as a regulatory asset, any portion of retiree
medical expense that was not yet provided for in customer rates. After receiving
rate  approval  for  recovery  of  such  costs, the Company began amortizing, as
retiree  medical  expense,  the  amounts  previously  deferred.

     The  Company  has  certain  Voluntary Employee Benefit Association ("VEBA")
trusts  to  fund  its  retiree medical benefits and contributed $0.5 million and
$3.0  million  to  the  trusts  in  2001  and  2000, respectively. There were no
contributions  to  the  VEBA trusts during 2002.  The Company can also partially
fund  retiree  medical  benefits  on  a  discretionary basis through an Internal
Revenue  Code  Section  401(h)  account.  No cash contributions were made to the
401(h)  account  in  2002,  2001  and  2000.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


     The  2002  postretirement  medical costs were developed based on the health
care  plan  in  effect  at January 1, 2002. As of December 31, 2002, the actuary
assumed that retiree medical cost increases in 2003 would be 7% and prescription
drug cost increases in 2003 would be 12%. The actuary also assumed that the rate
of  increase in retiree medical costs and prescription drug costs would decrease
uniformly  to  5%  in  2008  and  thereafter.  The  health  care cost trend rate
assumption  significantly  affects  the  amounts  reported.  For  example, a one
percentage  point  increase  in each year would increase the accumulated retiree
medical  obligation as of December 31, 2002 by $4.4 million and the aggregate of
the  service  and interest cost components of net periodic retiree medical costs
for  2002  by  $.4  million.

401(K)  PLANS  AND  PROFIT  SHARING PLANS.  The Company has defined contribution
plans,  commonly  referred to as 401(k) plans, covering the employees of certain
of  its  businesses or divisions. Certain of the 401(k) plans contain provisions
for  Company  matching  contributions. The amount expensed for the Company match
provisions  was  $1.1  million  for  2002,  2001  and  2000.
     The  Company  has profit sharing plans covering the employees of certain of
its businesses or divisions. Annual contributions are generally discretionary or
determined  by  a  formula,  which  contains  minimum contribution requirements.
Profit  sharing  expense  was  $.4 million for 2002 and $.3 million for 2001 and
2000.


NOTE  9.  STOCK-BASED  COMPENSATION

The  Company  has a long-term incentive plan providing for the issuance of up to
500,000  shares  of  non-qualified  common  stock  options,  adjusted  for  any
subsequent stock dividends and stock splits. During 2000, the Company's Board of
Directors  approved  a  second  such  plan  that  provides  for  the issuance of
non-qualified  stock  options  up to an amount not to exceed five percent of the
total  outstanding  shares  of  the  Company.  The  options are reserved for the
executives  and  directors  of  the  Company and are awarded based upon both the
Company's  and individual's performance. The options vest at the rate of 33 1/3%
per  year  beginning one year after the date of grant and expire ten years after
the  grant  date.
     The  exercise  price  of all the options granted is equal to the average of
the  high  and  low  market price on the options' grant date. Both the number of
options  granted  and  the exercise price are adjusted accordingly for any stock
dividends and stock splits occurring during the options' life. The fair value of
the  options  was  estimated  at  the date of grant using a Black-Scholes option
pricing  model  and  the  weighted average assumptions shown in the table below.

     The Company accounts for all stock options under the provisions and related
interpretations  of  Accounting Principles Board ("APB") Opinion 25, "Accounting
for  Stock  Issued  to  Employees." In accordance with SFAS 123, "Accounting for
Stock-Based  Compensation,"  the  Company  has chosen to continue accounting for
these  transactions  under  APB 25 for purposes of determining net income and to
present  the pro forma disclosures required by SFAS 123. If compensation expense
had  been determined in a manner consistent with the provisions of SFAS 123, the
Company's  net  income and earnings per share would have been reduced to the pro
forma  amounts  indicated  in  the  table  below.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


NOTE  10.  EARNINGS  PER  SHARE

The  Company  computes  earnings  per share ("EPS") in accordance with SFAS 128,
"Earnings  per Share." SFAS 128 requires the computation and presentation of two
EPS  amounts,  basic  and  diluted.  Basic  EPS  is  computed by dividing income
available to common shareholders by the weighted average number of common shares
outstanding during the period. The computation of diluted EPS is similar to that
of  basic  EPS  except  that  the  weighted  average  number  of  common  shares
outstanding  is  increased  to  include  any  shares  that would be available if
outstanding  stock  options and stock purchase contracts ("dilutive securities")
were  exercised.  The  diluted  EPS  calculation  excludes  the  affect of stock
options  when  their  exercise  prices  exceed  the  average market price of the
Company's  common  stock  during  the  period  and  excludes the affect of stock
purchase  contracts  when their reference price exceeds the average market price
of  common  stock  during  the  period.
     The following table provides the computations of basic and diluted earnings
per  share  for  the  years  ended  December  31,  2002,  2001  and  2000.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


NOTE  11.  BUSINESS  SEGMENTS

The  Company  follows  SFAS 131, "Disclosure about Segments of an Enterprise and
Related  Information," which specifies standards for reporting information about
operating  segments  ("business  segments")  in  annual financial statements and
requires selected information in interim financial statements. Business segments
are  defined  as  components  of  an  enterprise  about which separate financial
information  is  available  that  is  evaluated regularly by the chief operating
decision  maker,  or decision-making group, to make decisions on how to allocate
resources  and  to  assess  performance.  The  Company's  chief  operating
decision-making  group  is the Chief Executive Officer ("CEO") and certain other
executive  officers  who  report directly to the CEO. The operating segments are
organized  and managed separately because each segment offers different products
or  services.  The  Company  evaluates  the performance of its business segments
based  on  the  operating  income  generated.  Operating income does not include
income  taxes,  interest  expense,  discontinued  operations,  and non-operating
income  and  expense  items.
     Under  SFAS  131,  an  operating  segment  that  does  not  exceed  certain
quantitative levels is not considered a reportable segment. Instead, the results
of  all  segments that do not exceed the quantitative thresholds can be combined
and  reported  as  one  segment  and  referred  to as "all other." The Company's
propane,  pipelines  and  storage  business  segment  and information technology
services  segment did not meet these quantitative thresholds and could have been
grouped  into  the  "all  other"  category.  However, the Company has decided to
voluntarily  disclose  information  on  these  business  segments.
     The  Company currently operates four reportable business segments. They are
gas  distribution,  construction  services, information technology services, and
propane,  pipelines and storage. Refer to Note 1 for a brief description of each
business  segment.
     In  December  2001,  the  Company's  board  of directors approved a plan to
redirect  the Company's business strategy, which included the divestiture of its
engineering services business. The operating results of the engineering services
business  are  segregated  and  reported  as  discontinued  operations  in  the
Consolidated Statements of Operations. The Company sold its engineering services
business effective November 1, 2002. For further information refer to Note 14 of
the  Notes  to  Consolidated  Financial  Statements.
     The  accounting  policies  of the Company's four operating segments are the
same as those described in Note 1 except that intercompany transactions have not
been  eliminated  in determining individual segment results. The following table
provides  business  segment  information as well as a reconciliation ("Corporate
and  other")  of  the  segment  information  to  the  applicable  line  in  the
consolidated  financial  statements.  Corporate  and  other  includes  corporate
related  expenses  not  allocated  to  segments,  intercompany  eliminations and
results  of  other  smaller  operations.

NOTE  12.  INVESTMENT  IN  AFFILIATE

The  equity  method  of  accounting  is used for interests where the Company has
significant  influence,  but  does not control the entity. At December 31, 2002,
the  Company's only investment in affiliates was a 50% ownership interest in the
Eaton  Rapids Gas Storage System ("ERGSS"). The investment in the unconsolidated
affiliate  is  reported in deferred charges and other assets in the Consolidated
Statements  of  Financial Position.  ERGSS provides natural gas storage services
to the Company's Gas Distribution Business.  ERGSS had annual operating revenues
associated  with  services  provided  to  the  Gas Distribution Business of $3.2
million  in  2002  and $3.0 million in 2001 and 2000. The table below summarizes
the  financial  information  for  ERGSS.

NOTE  13.  COMMITMENTS  AND  CONTINGENCIES

CAPITAL  INVESTMENTS.  The  Company's plans for expansion and improvement of its
business properties are continually reviewed. Aggregate capital expenditures for
property  in 2003 are projected at approximately $33 million. The Company has no
plans  to  incur  additional  expenditures  for  business  acquisitions in 2003.

LEASE  COMMITMENTS.  The  Company  leases buildings, vehicles and equipment. The
resulting  leases are classified as operating leases in accordance with SFAS 13,
"Accounting  for  Leases."  A  significant portion of the Company's vehicles are
leased.  Leases  on the majority of the Company's new vehicles are for a minimum
of  twelve  months.  The  Company  has  the  right  to extend each vehicle lease
annually  and to cancel the extended lease at any time. During 2002, the Company
received  $4.4 million in proceeds from the sale of two buildings and land.  The
Company  is  leasing  these facilities back over the period January 2003 through
September  2005 for normal operating purposes.  The annual lease payments during
this  period  will  amount  to  approximately  $.5  million.
     The  Company's future minimum lease payments that have initial or remaining
noncancelable  lease  terms  in  excess of one year at December 31, 2002 totaled
$13.1  million  consisting  of  (in  millions): 2003 - $1.8; 2004 - $1.7; 2005 -
$1.3;  2006  -  $1.1;  2007  -  $1.1  and thereafter - $6.1. Total lease expense
approximated $2.2 million, $2.5 million and $2.3 million in 2002, 2001 and 2000,
respectively.  The  annual future minimum lease payments are less than the lease
expense  incurred  in  2000  through  2002 because most of the vehicle leases at
December  31,  2002  were  on  a  month-to-month  basis  and  were  subject  to
cancellation  at  any  time.  However,  management  expects  to renew or replace
substantially  all  leases.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


ENVIRONMENTAL ISSUES.  Prior to the construction of major natural gas pipelines,
gas  for  heating and other uses was manufactured from processes involving coal,
coke  or  oil. The Company owns seven Michigan sites, which formerly housed such
manufacturing facilities and expects that it will ultimately incur investigation
and  remedial  action  costs  at  some  of  these sites, and one other site. The
Company  has  closed  a  related  site  with  the  approval  of  the appropriate
environmental  regulatory  authority in the State of Michigan, and has developed
plans  and  conducted  preliminary  field investigations at two other sites. The
Company  is  in the process of estimating its liabilities and potential costs in
connection  with  these  sites,  but  the amounts of these estimates are not yet
available.  In  accordance  with  an  MPSC  accounting  order, any environmental
investigation  and remedial action costs will be deferred and amortized over ten
years. Rate recognition of the related amortization expense will not begin until
after  a  prudence  review  in  a  general  rate  case.

PERSONAL PROPERTY TAXES.  The Company and other Michigan utilities have asserted
that  Michigan's  valuation  tables  in  effect  prior  to  2000 resulted in the
substantial  overvaluation  of  utility  personal  property.  Valuation  tables
established  by  the  Michigan State Tax Commission ("STC") are used to estimate
the  reduction  in  value  of personal property based on the property's age.  In
1998,  the Company began filing its personal property tax information with local
taxing  jurisdictions,  using  a  revised  calculation  of the value of personal
property  subject  to taxation.  A number of local taxing jurisdictions accepted
the  revised calculation, and the Company recorded lower property tax expense in
1998 and subsequent years associated with the accepting taxing jurisdiction. The
Company  has  also  filed  appeals  to  recover excess payments made in 1997 and
subsequent  years  based  on the revised calculation and recorded lower property
tax  expense  as  a  result  of  the  filings.
      In  November  1999,  the  STC  approved  new  valuation  tables  that more
accurately  recognize the value of a utility's personal property. The new tables
became effective in 2000 and are being used for current year assessments in most
jurisdictions.  However,  several  local  taxing  jurisdictions have taken legal
action  attempting to prevent the STC from implementing the new valuation tables
and  have  continued  to  prepare  assessments  based  on the superceded tables.
     The  Company  will  seek  to  apply  the  new  tables  retroactively and to
ultimately  settle  the  pending tax appeals related to prior periods. This is a
solution supported by the STC in the past. The legal action, along with possible
additional  appeals by local taxing jurisdictions or negotiated settlements, may
delay the time period for recovery and ultimately impact the amount of recovery.
As  of  December  31,  2002,  the Company had a receivable of approximately $4.0
million recorded for the Company's estimated recovery of these prior year excess
property  tax  payments.
     On  November  7,  2002, the MPSC issued an order requiring each natural gas
and electric utility company subject to its jurisdiction to show cause as to why
each  such  utility  should  not  reduce  its  rates to reflect the new personal
property  valuation tables that were placed in effect in 2000 by the STC and why
it  should  not  refund  to  the  ratepayers any recovery amounts it receives as
refunds from taxing jurisdictions as it implements the new valuation tables. The
Company  filed  a  response  to the Order in December 2002. In its response, the
Company  stated  that  its  rates  should  not  be  reduced  and that refunds to
customers should not be required as a result of changes in personal property tax
multipliers. The reasons sighted by the Company were that (1) its existing rates
have  been  and currently are insufficient for it to earn its authorized rate of
return, (2) most of the potential for refunds relates to disputes arising out of
tax  years  prior  to the change in the tax multipliers, (3) for that portion of
the  receivable applicable to the change in the rate multipliers, customers have
already  received  the  benefits  of  the  resulting lower property tax expenses
through  certain  incentive  regulation  and income sharing rate mechanisms that
were  implemented  in  conjunction  with the Company's approved rates and (4) to
order  any  refund  to  customers of amounts received by the Company from taxing
authorities  would  constitute  prohibited  retroactive  ratemaking.

OTHER  CONTINGENCIES.  Under  the  terms of the Company's acquisition agreement,
the  former  owners  of  K&B  Construction were given the opportunity to receive
additional consideration if future results of operations exceed certain targeted
levels.  The amounts potentially payable to the former owners of K&B are subject
to  set-off  for certain liabilities. There has been no additional consideration
paid  in  connection  with  the K&B acquisition. The amounts potentially payable
have been placed in escrow and are reflected in restricted cash in the Company's
Consolidated  Statements  of  Financial  Position pending the outcome of certain
claims  and  litigation.
     In  the  normal  course  of business, the Company may be a party to certain
lawsuits  and  administrative  proceedings  before various courts and government
agencies.  These  lawsuits and proceedings may involve personal injury, property
damage,  contractual  issues  and  other  matters. Management cannot predict the
ultimate  outcome  of  any  pending  or  threatening  litigation or of actual or
possible  claims;  however,  management  believes resulting liabilities, if any,
will not have a material adverse impact upon the Company's financial position or
results  of  operations.

NOTE  14.  RESTRUCTURING  AND  DISCONTINUATION  OF  OPERATIONS

During  the  fourth  quarter of 2001, the Company announced a redirection of its
business  strategy  and  began  restructuring  its  corporate, business unit and
operational  structures. This involved the integration of the Company's Michigan
and  Alaska  gas  distribution  divisions  and  the  closure  of  the  Company's
Houston-based  engineering  and  construction  headquarters  and  related
consolidation  of  administrative  functions  in  Michigan. The redirection also
involved  the divestiture of the Company's engineering services business and the
ceasing  of operations in certain regions of the construction business that were
not likely to contribute to shareholder value in the near term. The new strategy
concentrates  more on profitable growth within each line of business and less on
acquisitions.
     The  Company  recorded $6.1 million of restructuring and impairment charges
in  the  fourth quarter of 2001 for the planned restructuring activities and the
ceasing  of  operations  in  certain  regions  of its construction business. The
charges  are  included  in  operating expenses in the Consolidated Statements of
Operations  and  include  severance  expense,  costs associated with terminating
leases,  writedowns  of  certain  construction  operations  and  other  related
expenses.  There  was no material adjustment to the restructuring and impairment
charges  during  2002.
     The  activities  of  the  Company's engineering services business have been
accounted  for  as  a  discontinued  operation  and,  accordingly, the operating
results and the loss on the disposal of this business segment are segregated and
reported  as  discontinued  operations  in  the  Consolidated  Statements  of
Operations.  Operating  results,  net  of  income  taxes,  from the discontinued
operations were $(1.1) million and $0.1 million for 2001 and 2000, respectively.
In  the fourth quarter of 2001, the Company recorded a loss of $5.0 million, net
of  income  taxes,  for  the estimated loss the Company expected to incur on the
disposal  of  its  engineering business segment, including estimated losses from
operations  during  the phase-out period. In November 2002, the Company sold its
engineering services business. The sale resulted in a loss, net of income taxes,
of  $5.0 million, including actual operating losses during the phase-out period.
There  was  a  difference  of  $10  thousand  between  the actual losses and the
estimated  losses,  which  is  included  in  discontinued  operations  for 2002.
     Components  of  amounts  reflected in the Consolidated Statements of Income
and  Consolidated  Statements of Financial Position for the engineering services
business  are  presented  in  the  following  table.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


NOTE  15.  QUARTERLY  FINANCIAL  INFORMATION  (UNAUDITED)

In  the opinion of the Company, the following quarterly information includes all
adjustments necessary for a fair statement of the results of operations for such
periods.  Earnings and dividends per share for each quarter are calculated based
upon the weighted average number of shares outstanding during each quarter. As a
result,  adding  the  earnings or dividends per share for each quarter of a year
may  not  equal  annual earnings or dividends per share due to changes in shares
outstanding throughout the year. Due to the seasonal nature of the Company's gas
distribution  business,  the results of operations reported on a quarterly basis
show  substantial  variations.
