                               SEMCO ENERGY, INC.
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


(1)  SIGNIFICANT  ACCOUNTING  POLICIES

     Under  the  rules and regulations of the Securities and Exchange Commission
for Form 10-Q Quarterly Reports, certain footnotes and other financial statement
information  normally  included  in  the  year-end financial statements of SEMCO
Energy, Inc. and its subsidiaries (the "Company") have been condensed or omitted
in  the accompanying unaudited financial statements.  These financial statements
prepared  by  the  Company  should  be  read  in  conjunction with the financial
statements  and  notes  thereto  included in the Company's 1999 Annual Report on
Form 10-K filed with the Securities and Exchange Commission.  The information in
the  accompanying financial statements reflects, in the opinion of the Company's
management,  all  adjustments  (which include only normal recurring adjustments)
necessary for a fair statement of the information shown, subject to year-end and
other  adjustments, as later information may require.  Certain reclassifications
have  been  made  to the prior periods' financial statements to conform with the
2000  presentation.

     USE  OF  ESTIMATES  - The preparation of financial statements in conformity
with  generally  accepted  accounting  principles  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.

     SUPPLEMENTAL CASH FLOW INFORMATION - Supplemental cash flow information for
the  three  months ended March 31, 2000 and 1999 is as follows (in thousands  of
dollars):

(2)  CAPITALIZATION

     REGISTRATION  STATEMENT  -  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 registration
statement  was  for the registration of debt securities, preferred stock, common
stock,  stock  purchase  contracts  and  stock purchase units of the Company and
trust  preferred  securities of the Capital Trusts and related guarantees in any
combination  up  to  $500  million.

                                      - 7 -


     In  April  2000,  SEMCO Capital Trust I issued 1.6 million shares of 10.25%
cumulative trust preferred securities ("Trust Preferred Securities") 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 Trust Preferred Securities to
invest  in  subordinated  debentures  of the Company bearing an interest rate of
10.25%  ("Subordinated  Debentures").  Also  in April 2000, the Company sold $30
million  of 8% Senior Notes due 2010 ("Senior Notes") in a public offering.  The
Company  used  the  entire  net  proceeds  from the sale of the Senior Notes and
Subordinated  Debentures  to  repay a portion of the bridge loan utilized in the
ENSTAR  Natural Gas Company acquisition, including a $56 million payment due May
1,  2000.

     COMMON  STOCK  EQUITY  - On April 18, 2000 the Company's Board of Directors
declared  a  regular  quarterly cash dividend of $.21 per share on the Company's
common  stock  (a  2.4% increase over the prior quarterly cash dividend of $.205
per  share).  The  dividend is payable on May 15, 2000 to shareholders of record
at  the  close  of  business  on  May  5,  2000.
     In  February  2000, the Company paid a quarterly cash dividend of $.205 per
share  on  its  common  stock.  The  total  cash dividend was approximately $3.7
million  of  which  $.7 million was reinvested by shareholders into common stock
through  participation  in  the  Direct Stock Purchase and Dividend Reinvestment
Plan  ("DRIP").  During  the  first  quarter of 2000, the DRIP purchased Company
common  stock  on  the  open  market to meet the dividend reinvestment and stock
purchase  requirements  of  its  participants.  Also during the first quarter of
2000,  the  Company  issued  approximately  18,000 shares of its common stock to
certain  of  the  Company's  employee  benefit  plans.

(4)     BUSINESS  SEGMENTS

     The  Company's  adoption  of  SFAS 131 addressing disclosure about business
segments  and  policies applicable to the disclosure are discussed in Note 12 in
the  Company's  1999  Annual  Report  on  Form  10-K.
     The  Company  operates  four  business  segments: (1) gas distribution; (2)
construction  services; (3) engineering 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 segment distributes
and  transports  natural  gas to approximately 255,000 customers in the state of
Michigan  and  approximately  102,000  customers  in  the  state of Alaska.  The
construction  services  segment  currently  does  business  in  the mid-western,
southern  and  southeastern  areas  of  the  United  States.  In  addition  to
constructing underground gas pipelines, the Company is expanding its underground
construction services into other industries such as telecommunications and water
supply.  The  engineering  services segment has offices in New Jersey, Michigan,
Louisiana  and  Texas  and  provides a variety of energy related engineering and
quality  assurance  services  in  several  states.  The  propane,  pipelines and
storage  segment  sells  approximately  5 million gallons of propane annually to
retail  customers  in  Michigan's  upper  peninsula  and northeast Wisconsin and
operates natural gas transmission, gathering and storage facilities in Michigan.
The  Company  sold  the  subsidiary  comprising  its  energy  marketing business
effective  March  31,  1999.
     The  accounting  policies  of  the operating segments are the same as those
described in Note 1 of the Notes to the Consolidated Financial Statements in the
Company's  1999 Annual Report on Form 10-K 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.

(5)     PRO  FORMA  INFORMATION

     On  November  1,  1999,  the  Company  acquired  the  assets  and  certain
liabilities  of  ENSTAR  Natural Gas Company and the outstanding stock of Alaska
Pipeline  Company (together known as "ENSTAR"). The Company acquired ENSTAR from
Ocean  Energy,  Inc.  ("Ocean  Energy")  for approximately $290 million in cash,
which included adjustments for working capital and the purchase of $58.7 million
of  ENSTAR's  debt  held by Ocean Energy, plus the accrued interest thereon. The
acquisition  has  been  accounted  for  using the purchase method of accounting.
Accordingly,  the  purchase price has been preliminarily allocated to the assets
purchased  and  the  liabilities assumed based on their estimated fair values at
the date of the acquisition, with the $134.4 million of purchase price in excess
of  these  estimated  fair  values  classified  as  goodwill  and amortized on a
straight-line  basis  over  40  years.
     The  following  pro  forma  amounts for operating revenue, consolidated net
income and earnings per share (basic and diluted) have been determined as if the
acquisition  of  ENSTAR  occurred on January 1, 1998, and illustrate the effects
of:  (1)  the  elimination  of activities between ENSTAR and Ocean Energy or its
predecessor,  Seagull  Energy,  Inc.,  that occurred prior to the closing of the
acquisition  by  the Company; (2) the adjustments resulting from the acquisition
by  the Company including increases in depreciation and amortization expense due
primarily to the amortization, over a 40 year period, of the goodwill associated
with  the  acquisition;  and  (3) the assumed public issuance of $165 million of
debentures,  $40  million  of  trust  preferred securities and approximately 6.8
million  shares  of  common  stock  of  the  Company  producing  net proceeds of
approximately $85 million and the resulting adjustments to interest expense from
these  issuances  (the  "Financing  Transactions").  The  Financing Transactions
represent  the  Company's current expectations regarding permanent financing for
the ENSTAR acquisition. The net proceeds from the Financing Transactions will be
used  primarily  to  retire  a  $290 million bridge loan facility of the Company
which  was  used  to  finance  the  ENSTAR  acquisition.
     The  pro  forma  amounts  do  not  reflect  any  potential  cost savings or
operating  synergies  that  may be realized following the acquisition of ENSTAR.

<FN>
(a)  The  decrease  in  operating  revenues  and  expenses  is  due primarily to
     the  energy  marketing  business,  which was sold effective March 31, 1999,
     offset partially  by  the  results  of  new  business  acquisitions.



(6)  COMMITMENTS  AND  CONTINGENCIES

     ENVIRONMENTAL  MATTERS  -  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  a number of other sites. The Company has submitted plans to the appropriate
environmental  regulatory  authority  in the State of Michigan to close one site
and  begin  work  at  another  site. The extent of the Company's liabilities and
potential costs in connection with these sites cannot reasonably be estimated at
this  time.  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.

                  PART I - FINANCIAL INFORMATION - (CONTINUED)


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


RESULTS  OF  OPERATIONS

     Net  income  of SEMCO Energy, Inc. and its subsidiaries (the "Company") was
$12.0 million (or $0.67 per share) for the quarter ended March 31, 2000 compared
to  $10.4 million (or $0.60 per share) for the quarter ended March 31, 1999.  On
a  weather-normalized  basis,  net  income  for  the  quarter  ended
March  31, 2000 would have been approximately $14.7 million (or $0.82 per share)
compared to approximately $11.1 million (or $0.63 per share) for the same period
of the prior year.  The net income for the first quarter of 1999 includes a gain
of  $.7  million  after  tax (or $0.04 per share) from the sale of the Company's
energy  marketing  business.
     Net income for the twelve months ended March 31, 2000 was $19.2 million (or
$1.08  per  share) compared to $11.9 million (or $0.72 per share) for the twelve
months  ended  March  31, 1999.  On a weather-normalized basis, net income would
have been approximately $25.0 million (or $1.40 per share) for the twelve months
ended  March  31,  2000  compared  to  approximately $17.1 million (or $1.03 per
share)  for  the  same  period of the prior year.  The net income for the twelve
months  ended  March  31, 1999 includes the gain of $.7 million after tax on the
sale  of  the  energy  marketing  business  plus  an extraordinary charge of $.5
million  after  tax  (or $0.03 per share) from the early retirement of long-term
debt.
     The  Company's  largest  business  segment,  natural  gas  distribution, is
seasonal  in  nature  and  depends  on the winter months for the majority of its
operating  revenue.  As  a result, a substantial portion of the Company's annual
results  of  operations  is  earned  during the first and fourth quarters of the
year.  In addition, the Company's construction services business segment is also
seasonal  in  nature  and  makes  most  of its income during the summer and fall
months  and  incurs  losses during the winter and spring months.  Therefore, the
Company's  results  of  operations for the three months ended March 31, 2000 and
1999  are  not  necessarily  indicative  of  results  for  a  full  year.

<FN>
(a)  The  decrease  in  operating  revenues  and  expenses is due primarily to the energy  marketing
     business,  which  was  sold  effective  March  31, 1999, offset partially by the
     results of new business acquisitions.


                                      - 11 -


     The  results  for  the  three  and  twelve months ended March 31, 2000 also
include  net  income of $2.2 million and $4.8 million, respectively, from ENSTAR
Natural Gas Company and Alaska Pipeline Company, which were acquired on November
1,  1999.  The  business  segment  analyses  and  other  discussions on the next
several  pages  provide additional information regarding variances in results of
operations  when  comparing  the  three and twelve month periods ended March 31,
2000  to  the  same  periods  of  the  prior  year.


PRO  FORMA  INFORMATION

     As  previously  mentioned,  on  November  1, 1999, the Company acquired the
assets and certain liabilities of ENSTAR Natural Gas Company and the outstanding
stock  of  Alaska  Pipeline Company (together known as "ENSTAR").  Note 5 of the
Notes  to  the Consolidated Financial Statements includes additional information
regarding the acquisition as well as a discussion of how the following pro forma
amounts  were  developed.
     The  pro  forma  amounts  do  not  reflect  any  potential  cost savings or
operating  synergies  that  may be realized following the acquisition of ENSTAR.

     Each  business segment is discussed separately on the following pages.  The
Company  evaluates  the  performance  of  its  business  segments  based  on the
operating  income  generated.  Operating  income  does not include income taxes,
interest  expense,  extraordinary  items, changes in accounting methods 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.  ENSTAR,  the  Alaska-based  operation,  was  acquired on
November  1, 1999. The acquisition of ENSTAR was accounted for as a purchase and
therefore  the consolidated financial statements and the table below include the
results  of  ENSTAR's  operations  since  November  1,  1999.  The  Michigan gas
distribution  operation  and  ENSTAR  are  referred  to  together  as  the  "Gas
Distribution  Business".
     Operating  income  for  the Gas Distribution Business was $28.7 million for
the quarter ended March 31, 2000 compared to $17.9 million for the quarter ended
March  31, 1999.  On a weather-normalized basis, the operating income of the Gas
Distribution  Business would have been approximately $33.0 million for the first
quarter  of  2000 compared to approximately $18.8 million for the same period of
the  prior  year.  Approximately  $11.2 million of the $14.1 million increase in
weather-normalized operating income for the first quarter of 2000, when compared
to the first quarter of 1999, represents the weather-normalized operating income
of  ENSTAR.

     GAS  SALES  MARGIN  -  During  the  first quarter of 2000, gas sales margin
increased  by  $15.4  million  when  compared to the first quarter of 1999.  The
increase  includes  approximately $14.5 million of gas sales margin from ENSTAR.
The  remaining  $.9  million of the increase is attributable to the Michigan gas
distribution  operation  and relates to gas sales margins from new customers and
sales  margins  earned  on  the  sale  of gas under the Company's gas supply and
storage  arrangement with TransCanada Gas Services, Inc. ("TransCanada"), offset
partially  by  a decrease in gas sales as a result of warmer weather and a shift
in  customers  to  transportation  as  a  result  of  their participation in the
Company's  aggregated  transportation  services  ("ATS")  program.
     The  gas  supply  and  storage arrangement with TransCanada pertains to the
Michigan  gas  distribution  operations.  Under  the  terms  of  the agreements,
TransCanada  provides  the  Company's  natural  gas requirements and manages the
Company's  natural  gas  supply  and  the  supply  aspects of transportation and
storage  operations  in  Michigan  for the three year period that began April 1,
1999.  TransCanada  supplies  the  gas  and related services to the Company at a
cost  below  the  $3.24  per  Mcf  that  the Company is authorized to charge its
Michigan  customers  for  gas.  As  a  result,  the  Michigan  gas  distribution
operation  retains  the  sales  margin on the sale of gas, subject to a customer
profit  sharing  mechanism.  Prior  to  April  1,  1999,  gas  sales  margin was
generated  primarily  from  distribution  fees  and  customer  fees  because the
Michigan  operation  was  not  allowed  to earn profits from the sale of the gas
commodity.  For  more  information  on  the  TransCanada  agreements,  the $3.24
authorized  gas  charge and the customer profit sharing mechanism, see Note 2 of
the  Notes to the Consolidated Financial Statements in the Company's 1999 Annual
Report  on  Form  10-K.
     Weather  during  the  first  quarter  of  2000 was 10.6% warmer than normal
in  Michigan  and  Alaska combined while the weather during the first quarter of
1999  was  2.1%  warmer than normal.  Under normal weather conditions, gas sales
margin  for the quarters ended March 31, 2000 and 1999 would have been higher by
approximately  $4.3  million  and  $1.0  million,  respectively.
     The  ATS  program, which was effective April 1, 1998, provides all Michigan
commercial and industrial 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 have switched to third-party gas
suppliers  are  recorded  in  gas  transportation  revenue rather than gas sales
revenue  because  the  Company  is  acting as a transporter for those customers.

                                      - 14 -


     Gas  sales  margin  for the twelve months ended March 31, 2000 increased by
$30.8  million  when  compared  to  the  twelve months ended March 31, 1999. The
increase  includes  approximately $26.1 million of gas sales margin from ENSTAR.
The  remaining  $4.7 million of the increase is attributable to the Michigan gas
distribution  operation  and relates to gas sales margins from new customers and
sales  margins  earned  on  the  sale of the gas commodity, some of which may be
non-recurring.  These  increases  were  offset partially by the impact of warmer
weather  and  a  shift  in  customers  to  transportation  as  a result of their
participation  in  the  Company's  ATS  program.
     Weather during the twelve months ended March 31, 2000 was 10.7% warmer than
normal  in  Michigan  and  Alaska  combined, while the weather during the twelve
months  ended March 31, 1999 was 12.5% warmer than normal.  Under normal weather
conditions, gas sales margin for the twelve months ended March 31, 2000 and 1999
would  have  been  higher  by  approximately  $8.6  million  and  $7.7  million,
respectively.  The  impact  of  weather  on  gas  sales margin during the twelve
months  ended  March  31,  2000  was larger than during the same period of 1999,
despite the slightly cooler weather, because of the increased customer base as a
result  of  the  ENSTAR  acquisition.  A  significant  increase in customer base
causes any variation from normal weather to have a more pronounced impact on gas
sales  margin.

     GAS  TRANSPORTATION  REVENUE - For the three months and twelve months ended
March  31,  2000,  gas transportation revenue increased by $4.9 million and $9.8
million, respectively, when compared to the same periods of 1999.  The increases
are  due in part to ENSTAR's transportation revenues during the three months and
twelve  months  ended  March  31,  2000  of  $4.1  million  and  $7.1  million,
respectively.  The  remainder  of  the  increases  during  both  periods relates
primarily  to  customers participating in the new ATS program and an increase in
general  transportation  revenue  due  to  increased transportation volumes.  As
discussed  above,  the  increase  in  gas  transportation revenue as a result of
participation in the ATS program is generally offset by a corresponding decrease
in  gas  sales  margin.

     OPERATING  EXPENSES  -  The  operating  expenses  of  the  Gas Distribution
Business  increased by $9.4 million during the three months ended March 31, 2000
compared  to  the  three  months  ended  March  31,  1999.  Operating  expenses
attributable  to ENSTAR account for $8.9 million of the increase.  The remaining
$.5  million  of  the increase relates to the Michigan operation.  Approximately
$.2 million of the increase in Michigan operating expenses was due to additional
depreciation  expense  and  property  taxes on new property, plant and equipment
placed  in  service  and  the  remainder  of  the  increase was due primarily to
increased  payroll  expenses.
     During the twelve months ended March 31, 2000, operating expenses increased
by  $16.9  million  when  compared  to  the  twelve months ended March 31, 1999.
Approximately  $14.9  million  of  the  increase is attributable to ENSTAR.  The
remainder  of the increase relates to the Michigan operation.  Approximately $.7
million  of  the  increase  in  Michigan operating expenses is due to additional
depreciation  on  new  property,  plant  and  equipment  placed  in  service and
approximately  $.7  million  is due to increased information technology expenses
related  primarily to year-2000 computer remediation.  There was also an overall
increase  in  general and administrative operating expenses of approximately $.9
million  due  primarily  to  higher  payroll  related  costs.
     The  increases  in  Michigan  operating expenses in the twelve month period
ended  March 31, 2000 were offset partially by a $.3 million decrease in general
taxes.  The  decrease in general taxes is made up of a reduction of $1.3 million
in  property  taxes  which  the Company booked based on pending appeals of prior
years'  personal  property  assessments  in  Michigan and new property valuation
tables  approved  by  the  State  of  Michigan  in  1999, offset partially by an
increase  in  property  taxes  associated  with  additional  property, plant and
equipment  placed  in  service  and  an  increase  in Michigan business tax. The
Company  filed  the appeals over the past three years claiming that its Michigan
utility  property  was  over-assessed.  The new valuation tables approved by the
state  of  Michigan  are  consistent  with the Company's claim regarding utility
property  assessments  and  thus  significantly  increases  the  likelihood  of
recovering  the  overpaid  property  taxes.

     OPERATING  REVENUES  -  The operating revenues of the construction services
segment  ("Construction Services") increased by $9.9 million, or more than 200%,
during  the  first  quarter  of 2000 when compared to the first quarter of 1999.
The  increase  is  due primarily to the revenues of three contruction businesses
acquired  after the first quarter of 1999.  Operating revenues during the twelve
months  ended  March 31, 2000 increased by $40.3 million, or 145%, when compared
to  the  twelve  months  ended  March  31,  1999  due primarily to the timing of
business  acquisitions.  Refer  to  Note  3  of  the  Notes  to the Consolidated
Financial  Statement  in  the  Company's 1999 Annual Report on Form 10-K for the
acquisition  dates of all construction businesses acquired during the past three
years

     OPERATING  INCOME  - Construction Services' seasonal operating loss for the
first  quarter  of  2000 was $2.3 million compared to $1.2 million for the first
quarter of 1999.  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 income during the summer and fall
months.  The  increased  operating  loss  for  the  first  quarter  of 2000 when
compared  to  the first quarter of 1999 was due primarily to the seasonal losses
of the three business acquired  after the first quarter of 1999.  As the Company
expands  its  construction  business,  the  seasonal  losses  and profits become
proportionally  larger.
     Operating  income  for  the twelve months ended March 31, 2000 increased by
$1.8  million  when  compared  to  the same period of 1999.  The increase is due
primarily to the operating income of the businesses acquired since February 1999
and  the  absence  during  the  twelve  months ended March 31, 2000 of operating
losses from an overhead-line construction company that was started in Florida in
January  of  1998.  The  operations  of  this  start-up  business were halted in
mid-1998  in  response  to  lower  than  expected  business levels and earnings.
Construction  Services'  results  for  the  twelve  months  ended March 31, 1999
include  an  operating  loss  of  $.7  million from this overhead-line business.

     OPERATING  REVENUES  -  The  engineering  services  segment  ("Engineering
Services")  had operating revenues of $5.5 million during the three months ended
March  31,  2000 compared to $5.7 million for the same period of the prior year.
The  decrease  in  operating  revenues  was  due  primarily  to  a  reduction in
engineering  projects  that  began  during  the first half of 1999.  Engineering
projects  for  the  gas  distribution industry have been delayed due to the cash
flow  impact on the industry of warmer weather during the past few years.  Also,
many  pipeline construction and engineering projects scheduled for 1999 were cut
back  or  delayed due to gas market uncertainty and lower oil prices in 1998 and
early  1999.  Oil  prices have since recovered significantly and a turnaround in
business  for  2000  may  occur  as  new  and  delayed  engineering projects are
released.
     The  decrease  in revenues caused by the reduction in available engineering
projects  was offset partially by revenues from other lower margin jobs accepted
and performed during the first quarter of 2000.  The lower margin jobs covered a
portion  of  Engineering  Services'  fixed  overhead  costs.
     During  the  twelve  months  ended  March  31,  2000, Engineering Services'
operating  revenues  decreased  by  approximately  $26.6 million from the twelve
months ended March 31, 1999.  The decrease was due primarily to the reduction in
available  engineering projects, including turn-key projects, caused by the same
factors  discussed  with  respect  to  the  first  quarter.

     OPERATING  INCOME  -  Operating  income  for  Engineering  Services was $.1
million  for  the  first  quarter  of 2000 compared to $.5 million for the first
quarter  of  1999.  The decrease was due primarily to the reduction in available
engineering projects.  As discussed above, a turnaround in business for 2000 may
occur as new and delayed engineering projects are released in response to higher
oil  prices.
     Operating  income  decreased by $3.9 million during the twelve months ended
March  31,  2000  when  compared  to  the  same  period  of the prior year.  The
significant  decrease  in  operating income was due primarily to the decrease in
operating  revenues  and corresponding project costs as a result of the deferral
of  engineering  projects  discussed  previously,  and  unanticipated  ground
restoration and clean-up costs incurred during the twelve months ended March 31,
2000  related  to  a  large  turn-key project completed during the twelve months
ended  March  31,  1999.

     OPERATING REVENUES - For the three months and twelve months ended March 31,
2000,  the  operating  revenues  of the Company's propane, pipelines and storage
business  increased  by $.1 million and $.3 million, respectively, when compared
to  the  same  periods  of 1999.  The increases during both the three and twelve
month  periods were due to higher propane distribution revenues offset partially
by  slightly  lower  pipeline  revenues  due  to  the absence of revenues from a
pipeline  that  was  sold  in  mid-1999.

     OPERATING  INCOME  -  The  operating income from the propane, pipelines and
storage  business  decreased during the three months ended March 31, 2000 by $.3
million  when  compared  to  the first quarter of 1999.  The decrease during the
first quarter of 2000 was caused primarily by higher propane costs, which reduce
propane  margins,  and  the absence of operating income from a pipeline that was
sold  in  mid-1999.
     Operating  income  was  $2.0 million for both the twelve months ended March
31, 2000 and the same period of 1999.  Operating revenues were higher during the
twelve  months  ended  March 31, 2000, as discussed above, and pipeline expenses
were lower.  However, these items were offset primarily by higher propane costs.

     DIVESTITURE  OF  ENERGY  MARKETING  BUSINESS  - The Company sold its energy
marketing  business  effective March 31, 1999.  The divestiture generated a gain
of  $1.1  million  ($.7 million after tax) which is reflected in the results for
the  three  months  and  twelve  months  ended  March  31,  1999.

     DIVESTITURE  OF  NOARK  INVESTMENT - The Company sold its investment in the
NOARK  Pipeline  System  Partnership  ("NOARK")  in  1998  after  a  number  of
write-downs  and  reserve  adjustments  related  to  the  investment.  Refer  to
Management's  Discussion  and  Analysis  and  Note  15  in  the  Notes  to  the
Consolidated  Financial  Statements  in the Company's 1999 Annual Report on Form
10-K  for  additional  information  related  to  the  NOARK  investment.

     INTEREST  EXPENSE  -  During  the  first  quarter of 2000, interest expense
increased  $4.8  million compared to the first quarter of 1999.  The increase is
due  primarily  to  increases  in  debt  levels to finance the Company's capital
expenditure  and  business  acquisition  programs  and  for  general  corporate
purposes, offset partially by $2.1 million of income recognized on interest rate
hedge  instruments  during the first quarter of 2000.  The Company incurred $290
million  of  additional  short-term  debt  on  November  1,  1999 to finance the
acquisition  of  ENSTAR ("bridge loan").  Approximately $5.9 million of interest
expense  during the first quarter of 2000 relates to the bridge loan.  Also, $.8
million  of the $5.9 million in interest expense associated with the bridge loan
is  amortization of debt costs.  Debt costs related to the bridge loan are being
amortized  over  the  expected  life  of  the  loan.
     Interest  expense  for  the twelve months ended March 31, 2000 increased by
$10.4  million  when  compared to the same period in 1999.  The increase between
the  twelve-month  periods  is  due  generally to the same items that caused the
increase  between  quarterly  periods,  including  the  $2.1  million  of income
recognized on interest rate hedge instruments during the first quarter of 2000 .
Approximately  $10.1  million of interest expense during the twelve months ended
March  31,  2000  relates  to  the bridge loan, of which $1.5 million represents
amortization  of  debt  costs  associated  with  the  loan.

     OTHER  INCOME  -  Other  income  for  the three months ended March 31, 2000
increased  by  $.6  million  when  compared  to  the first quarter of 1999.  The
increase  is  due  in  part  to  a  $.4 million increase in equity income from a
partnership  investment in a gas storage facility, most of which is likely to be
non-recurring.  The remainder of the increase is due primarily to an increase in
gains  on  property  sales.
     Other  income  for the twelve months ended March 31, 2000 increased by $2.7
million  when  compared  to  the  same twelve months of 1999.  Approximately $.8
million  of  the increase between twelve month periods relates to life insurance
proceeds  received  upon  the  death of a retired company executive, $.7 million
relates  to  gains  on  the  sale of various property, $.6 million relates to an
increase  in  equity  income  from  partnership investments and the remainder is
attributable  to  higher  miscellaneous  non-operating  income.

INCOME  TAXES

     Income  taxes  for  the three months and twelve months ended March 31, 2000
increased  by  $2.1  million and $.9 million, respectively, when compared to the
same  periods of the prior year.  The change in income taxes, when comparing one
period  to  another,  is  due  primarily  to changes in pre-tax earnings and any
adjustments  necessary  for  compliance  with  tax  laws  and  regulations.


EXTRAORDINARY  ITEM

     The  Company  incurred  an extraordinary charge of $.5 million after-tax in
the  second  quarter  of 1998 for the early redemption of all of its outstanding
8.625%  debentures  due  April 15, 2017.  The charge is reflected in the results
for  the  twelve  months  ended  March  31,  1999.

     The  Company  has  spent  approximately  $9.1 million on property additions
during  the  first  three  months of 2000 and anticipates spending approximately
$40.9  million on property additions during the remainder of 2000.  In addition,
the  Company  may incur additional expenditures for business acquisitions during
the  remainder  of  2000.

     CASH  FLOWS  FROM  OPERATIONS  - Net cash from operating activities for the
three  months  ended March 31, 2000, as compared to the same three months of the
prior  year,  decreased  by $17.2 million. The change in operating cash flows is
significantly  influenced 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 the
timing  of  cash  receipts  and  payments.
     CASH  FLOWS  FROM  FINANCING - During the three months ended March 31, 2000
and  1999,  the  Company used $27.2 million and $43.0 million, respectively, for
financing  activities.

     In April 2000 the Company's Board of Directors declared a regular quarterly
cash  dividend  of  $.21  per  share on the Company's common stock, which was an
increase  of  2.4%  over  the  prior  quarterly  cash dividend.  The dividend is
payable  on  May  15, 2000 to shareholders of record at the close of business on
May  5,  2000.
     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 registration statement was for the
registration  of  debt securities, preferred stock, common stock, stock purchase
contracts and stock purchase units of the Company and trust preferred securities
of  the  Capital  Trusts  and  related  guarantees in any combination up to $500
million.
     In  April  2000,  SEMCO Capital Trust I issued 1.6 million shares of 10.25%
cumulative trust preferred securities ("Trust Preferred Securities") 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 Trust Preferred Securities to
invest  in  subordinated  debentures  of the Company bearing an interest rate of
10.25%  ("Subordinated  Debentures").  Also  in April 2000, the Company sold $30
million  of 8% Senior Notes due 2010 ("Senior Notes") in a public offering.  The
Company  used  the  entire  net  proceeds  from the sale of the Senior Notes and
Subordinated  Debentures to repay a portion of the ENSTAR bridge loan, including
a  $56  million  payment  due  May  1,  2000.

     FUTURE  FINANCING  -  In general, the Company funds its capital expenditure
program  and  dividend payments with operating cash flows and the utilization of
short-term  lines  of  credit.  When appropriate, the Company will refinance its
short-term  lines with long-term debt, common stock or other long-term financing
instruments.  At  March  31,  2000,  the  Company had $110 million of short-term
credit  facilities,  of  which  $49  million  was  unused.
     As  discussed  above,  the  Company  has  registered  up to $500 million of
securities  under  the registration statement, of which $70 million was utilized
to  issue  securities  during  April  of  2000.
     The  Company  expects  to  acquire  additional  businesses in 2000 and will
likely  raise the required capital through a combination of utilizing short-term
lines  of credit and issuing long-term debt or equity. The Company also plans to
refinance  the  ENSTAR bridge loan in 2000 with a combination of long-term debt,
equity  and  trust  preferred securities. The bridge loan matures on October 30,
2000.  Payments of $56,000,000 are required on May 1, 2000 and August 1, 2000 if
the  bridge loan is not prepaid prior to such dates. As discussed above, the net
proceeds  from  securities  issued in April 2000 were used to repay a portion of
the  bridge  loan  including  the  May  1,  2000  payment.
     The  Company's  ratio  of earnings to fixed charges was 2.12 for the twelve
months  ended  March  31,  2000.


NEW  ACCOUNTING  STANDARD

     In  June of 1998, the Financial Accounting Standards Board issued Statement
of  Financial  Accounting  Standards  No.  133,  "Accounting  for  Derivative
Instruments  and  Hedging  Activities"  ("SFAS  133").  SFAS  133  establishes
accounting  and  reporting  standards requiring that every derivative instrument
(including  certain  derivative  instruments  embedded  in  other  contracts) be
recorded  in the statement of financial position as either an asset or liability
measured  at its fair value.  SFAS 133 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.
     SFAS  133 is effective for fiscal years beginning after June 15, 2000.  The
Company  is  studying  the  effects of SFAS 133 but does not expect it to have a
material  impact  on the Company's liquidity, financial condition and results of
operations.
