                                     PART I


ITEM  1.     BUSINESS


SEMCO  ENERGY,  INC.

SEMCO  Energy,  Inc. is a diversified energy services and infrastructure holding
company  headquartered  in  southeastern  Michigan.  It  was  founded in 1950 as
Southeastern  Michigan Gas Company. SEMCO Energy, Inc. and its subsidiaries (the
"Company")  operate  four  business segments: (1) gas distribution; (2) pipeline
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 sold the subsidiary comprising its energy
marketing  business  effective  March  31,  1999.  In addition, several business
acquisitions  were  made  during  1999.  These acquisitions are discussed in the
following  business  segment  sections.  The  Company  had  approximately  1,632
employees  at  December  31,  1999.

GAS  DISTRIBUTION

The Company's gas distribution business segment operates in Michigan and Alaska.
The  Alaska-based  operation,  which  consists of ENSTAR Natural Gas Company and
Alaska  Pipeline  Company (together known as "ENSTAR"), was acquired on November
1,  1999 for approximately $290,000,000. 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  success  of  the ENSTAR acquisition is, in part, dependent on the synergies
obtained   in  combining  ENSTAR  with  the  Company's  other  gas  distribution
operations, the Company's ability to operate ENSTAR in accordance with its plans
and  the  Company's ability to accomplish its permanent financing related to the
ENSTAR  acquisition  in  a timely and cost-effective manner in light of changing
conditions  in  the  capital  markets.

<PAGE>
     The Michigan gas distribution operation and ENSTAR are referred to together
as the "Gas Distribution Business".  The Michigan gas distribution operation and
ENSTAR  Natural  Gas  Company   operate  as  divisions  of  SEMCO  Energy,  Inc.
SEMCO Energy Gas Company, which  had  conducted  the  Michigan  gas distribution
operation,  was  merged  into  SEMCO  Energy, Inc. on December 31, 1999.  Alaska
Pipeline  Company  operates  as  a  subsidiary  of  SEMCO  Energy,  Inc.
     The  Gas  Distribution  Business  distributes and transports natural gas to
residential,  commercial  and  industrial customers and is the Company's largest
business  segment.  Set forth in the table below is gas sales and transportation
information  for  the  past  three  years:

     Refer  to  Note 12 of the Notes to the Consolidated Financial Statements on
pages  60  and  61  of  the  Company's 1999 Annual Report to Shareholders, which
information  is  incorporated  herein  by reference from exhibit 13 to this Form
10-K,  for  the Gas Distribution Business' operating revenues, operating income,
assets  and  other  financial  information  for  the  past  three  years.

GAS  SALES - Gas sales  revenue  is  generated  primarily  through  the sale and
delivery  of   natural  gas  to  residential  and  commercial  customers.  These
customers  use  natural  gas  mainly  for space heating purposes.  Consequently,
weather  has a significant impact on sales.  Given the impact of weather on this
business  segment,  most  of  its  gas  sales revenue is earned in the first and
fourth  quarters  of  the  calendar year.  Revenues from gas sales accounted for
50%,  26%  and  28%  of  consolidated operating revenues in 1999, 1998 and 1997,
respectively.   If  operating  revenues  from  the  Company's  energy  marketing
business,  which  was  sold effective March 31, 1999, are excluded, gas sales by
the  Gas  Distribution  Business  would  have  accounted for 66%, 68% and 88% of
consolidated  operating  revenues  for  those  three  years.
     Competition  in the gas sales market arises from alternative energy sources
such  as  electricity,  propane and oil.  However, this competition is inhibited
because of the time, inconvenience and investment for residential and commercial
customers to convert to an alternate energy source when the price of natural gas
fluctuates.  For  more  information  on  competition  for  the  Gas Distribution
Business,  refer  to  the  section  titled  "Outlook"  on pages 29 and 30 of the
Company's  1999 Annual Report to Shareholders, which information is incorporated
herein  by  reference  from  exhibit  13  to  this  Form  10-K.
          An aggregation tariff, 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 plus a gas
load  balancing  fee.  Refer  to the sections titled "Gas Sales Margin" and "Gas
Transportation  Revenue"  on pages 26 and 27 of the Company's 1999 Annual Report
to  Shareholders,  which  information  is  incorporated herein by reference from
exhibit  13  to  this Form 10-K, for further information regarding the impact of
the  aggregation  tariff  on  gas  sales  and  transportation  revenue.

                                      - 2 -

TRANSPORTATION - The Gas  Distribution Business provides transportation services
to  its  large-volume  commercial and industrial customers.  This service offers
those  customers the option of purchasing natural gas directly from producers or
marketing  companies while utilizing the Gas Distribution Business' distribution
network  to  transport  the  gas  to  their  facilities.
     Alaska  Pipeline  Company  ("APC")  owns  and operates the only natural gas
transmission  lines  in its service area that are operated for utility purposes.
APC's  transmission  system  delivers  natural  gas  from  producing  fields  in
southcentral  Alaska to ENSTAR's Anchorage-based gas distribution system.  APC's
only  customer  is  ENSTAR  Natural  Gas  Company.
     The market price of alternate energy sources such as coal, electricity, oil
and  steam  is  the   primary   competitive  factor  affecting  the  demand  for
transportation.  Certain large industrial customers have some ability to convert
to  another  form of energy if the price of natural gas increases significantly.
Partially offsetting the impact of price sensitivity has been the use of natural
gas  as  an  industrial  fuel because of clean air legislation and the resultant
pressures  on  industry  and  electric  utilities to reduce emissions from their
plants.
     As  is  the  case  with  many  gas  distribution  utilities, there has been
downward  pressure  on  transportation  rates  due  to  the  potential  risk for
industrial  customers  and electric generating plants located in close proximity
to  interstate  natural gas pipelines to 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 and would continue
to  address  any  such  efforts  by  offering  special  services and contractual
arrangements  designed  to  retain  these  customers  on  the  Company's system.
Customers  in  ENSTAR's service territory are currently precluded from bypassing
ENSTAR's  transportation and distribution system due to the limited availability
of gas transmission systems and the large distances between producing fields and
the  locations  of  current  customers.

CUSTOMER  BASE - At  December  31, 1999, the Michigan gas distribution operation
had  approximately  255,000  customers.  The largest concentration of customers,
approximately  100,000,  is  located  in  southeastern  Michigan.  The remaining
Michigan  customers  are located in and around the following communities: Battle
Creek,  Albion,  Holland,  Three  Rivers,  Niles,  Marquette  and Houghton.  The
Michigan  customer  base  is  diverse  and  includes residential, commercial and
industrial  customers.  The  largest  customers  include  power  plants,  food
production  facilities,  paper  processing  plants,  furniture manufacturers and
others  in  a  variety  of other industries.  The average number of customers in
Michigan  has  increased  by  an average of approximately 3% annually during the
past  three  years.  By  contrast,  the  customer  growth  rate for the U.S. gas
distribution  industry  has  averaged  approximately 1% annually during the past
three  years.
     At  December  31,  1999,  ENSTAR had approximately 102,000 customers in and
around  the  Anchorage,  Alaska area including the communities of Big Lake, Bird
Creek,  Butte,  Chugiak, Eagle River, Eklutna, Girdwood, Houston, Indian, Kenai,
Knik,  Nikiski,  Palmer,  Peters Creek, Portage, Sterling, Soldotna, Wasilla and
Whittier.  ENSTAR  is  the  sole  distributor  of  natural  gas  to  the greater
Anchorage  metropolitan area, and its service area encompasses approximately 50%
of  the  population of Alaska.  ENSTAR has two types of customers: gas sales and
transportation.  Gas  sales  customers are primarily residential and commercial.
ENSTAR provides transportation service to power plant sites, a liquified natural
gas  plant,  an ammonia plant, and hundreds of commercial locations on behalf of
gas  producers  and gas marketers. The average number of customers at ENSTAR has
increased  by  an  average  of  approximately  3% annually during the past three
years.

GAS  SUPPLY - The Gas  Distribution Business has agreements with TransCanada Gas
Services,  Inc.  ("TransCanada"), under which 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.  For additional information about
this  agreement,  refer  to  Note  2  of the Notes to the Consolidated Financial
Statements  on  pages  47  and  48  of  the  Company's  1999  Annual  Report  to
Shareholders, which information is incorporated herein by reference from exhibit
13  to  this  Form 10-K.  The Gas Distribution Business owns underground storage
facilities  in  Michigan  with  a  working  capacity  of  5.0 billion cubic feet
("Bcf").  In  addition,  it  leases  6.5  Bcf  of  storage from Eaton Rapids Gas
Storage  System  and  4.5  Bcf  from  non-affiliates in Michigan.  The owned and
leased  storage  capacity  equals 35% to 40% of the Company's average annual gas
sales volumes in Michigan.  SEMCO Gas Storage Company (an affiliated company) is
a  50%  owner  of  Eaton  Rapids  Gas  Storage  System.

     ENSTAR  has a gas purchase contract (the "Marathon Contract") with Marathon
Oil  Company ("Marathon") that has been approved by the Regulatory Commission of
Alaska  ("RCA")  and  is  a  "requirements"  contract  with  no  specified daily
deliverability or annual take-or-pay quantities.  Marathon has agreed to deliver
all  of  ENSTAR's  gas  requirements  in  excess  of those provided for in other
presently  existing  gas  supply contracts, subject to certain exceptions, until
the  commitment  has been exhausted.  However, ENSTAR's purchase obligations and
Marathon's  delivery obligations are set at specified annual amounts after 2001.
The  contract  has  a base price and is subject to an annual adjustment based on
changes  in the price of certain traded oil futures contracts plus reimbursement
for  any  severance  taxes  and  other  charges.
     ENSTAR also has an RCA-approved gas purchase contract with the Municipality
of Anchorage, Chevron U.S.A., Inc. and ARCO Alaska, Inc. (the "Beluga Contract")
which  provides  for  the delivery of up to approximately 220 Bcf of gas through
the  year 2009.  The pricing mechanism in the Beluga Contract is similar to that
contained  in  the  Marathon  Contract.
     Based  on  gas  purchases during the twelve months ended December 31, 1999,
which  are  not  necessarily  indicative  of the volume of future purchases, gas
reserves  committed  to  ENSTAR  under  the  Marathon  and  Beluga Contracts are
sufficient  to  supply  all of ENSTAR's expected gas supply requirements through
the  year  2001.  After  that  time  supplies  will still be available under the
Marathon  and  Beluga  contracts  in accordance with their terms, but at least a
portion  of ENSTAR's requirements are expected to be satisfied outside the terms
of  these  contracts,  as  currently  in  effect.
     The  Michigan-based  gas  distribution  operation  is  served by four major
interstate  pipelines:  (1)  Panhandle  Eastern  Pipe Line Company; (2) Northern
Natural  Gas  Company;  (3)  Great  Lakes  Gas  Transmission Company and (4) ANR
Pipeline  Company.  Currently,  ENSTAR's  supply  source,  primarily  though the
Marathon and Beluga Contracts, is confined to the Cook Inlet area with no direct
access  to other natural gas pipelines.  However, the Cook Inlet area is home to
major  gas producing fields, with proven and producing reserves of approximately
2.6  trillion  cubic feet ("Tcf").  An additional 2.3 Tcf of undiscovered gas in
the  Cook  Inlet  area has been estimated by the United States Geological Survey
and  Minerals  Management  Service.

RATES  AND  REGULATION - The rates  of 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 ("MPSC") authorizes the rates charged to all of the remaining
Michigan  customers.  ENSTAR  is  subject  to  regulation  by  the RCA which has
jurisdiction  over,  among  other  things,  rates,  accounting  procedures,  and
standards  of  service.  The  RCA  order  approving the Company's acquisition of
ENSTAR  provides  that  ENSTAR's  existing  rates remain in effect on an interim
basis  and  requires the Company to file revenue requirement and cost of service
information  by  July  1,  2000.
     Management  periodically  reviews  the  adequacy  of  the  Gas Distribution
Business'  rates  and  files  requests  for rate increases whenever it is deemed
necessary  and  appropriate.  However,  a  recent  rate case includes provisions
limiting the Company's ability to request a rate increase in Michigan during the
three year period that began April 1, 1999.  Refer to Note 2 of the Notes to the
Consolidated  Financial  Statements on pages 47 through 49 of the Company's 1999
Annual  Report  to  Shareholders,  which  information  is incorporated herein by
reference  from  exhibit  13  to  this  Form  10-K,  for  further information on
regulatory  matters  including  recent  regulatory  orders  and  rate  cases.

ENVIRONMENTAL  MATTERS - The Gas  Distribution  Business  currently  owns  seven
Michigan  sites  which  formerly housed manufactured gas plants.  In the earlier
part  of  the 20th century, gas was manufactured from processes using coal, coke
or  oil.  By-products  of  this  process  have  left some contamination at these
sites.  The  Gas  Distribution  Business  has submitted plans to the appropriate
regulatory  authority  in the State of Michigan to close one site and begin work
at  another site.  For further information, refer to Note 14 of the Notes to the
Consolidated  Financial  Statements  on  pages  62  and 63 of the Company's 1999
Annual  Report  to  Shareholders,  which  information  is incorporated herein by
reference  from  exhibit  13  to  this  Form  10-K.

income,  assets  and  other  financial  information  for  the  past three years.


PIPELINE  CONSTRUCTION  SERVICES

The  Company's  pipeline construction services segment ("Construction Services")
operates  in the mid-western and southeastern areas of the United States and has
offices  in Michigan, Tennessee, Kansas, Iowa, Georgia, and Texas as of December
31,  1999.  Its  primary  service  is  underground  pipeline  installation  and
replacement  for the natural gas distribution industry. During 1999, the Company
made  four  business acquisitions that not only expanded the geographic reach of
Construction  Services  but  also  expanded  underground  construction  service
offerings  in new industries such as telecommunications and water supply.  As of
December  31,  1999,  Construction  Services was comprised of six companies that
were all acquired during the past three years: (1) Sub-Surface Construction Co.;
(2)  King  Energy  &  Construction  Co.;  (3)  K&B  Construction, Inc.; (4) Iowa
Pipeline  Associates,  Inc.;  (5)  Flint  Construction  Co.;  and  (6)  Long's
Underground Technologies, Inc.  On December 31, 1999, King Energy & Construction
Co.  was  merged  into  Flint  Construction Co.  There is additional information
regarding  these  acquisitions  in  Note  3  of  the  Notes  to the Consolidated
Financial  Statements on pages 49 through 51 of the Company's 1999 Annual Report
to  Shareholders,  which  information  is  incorporated herein by reference from
exhibit  13  to  this  Form  10-K.
     Construction  Services  had  operating  revenues,  excluding   intercompany
transactions,  of  $49,965,000,  $16,621,000,  and  $7,484,000 in 1999, 1998 and
1997,  respectively.  These  operating  revenues accounted for 17%, 7% and 3% of
consolidated  operating revenues, excluding energy marketing operating revenues,
during  those  years.
     The  natural  gas  construction  services industry is comprised of a highly
fragmented  group  of  companies focused primarily on regional or local markets.
The  top  six  construction companies in the United States have less than 10% of
the  market.  Approximately  30%  of  the market represents work done by utility
companies'  in-house  construction  operations  with the remainder of the market
being  served  by  a  large number of small  and medium-size companies. For more
information  on  competition  for  Construction  Services,  refer to the section
titled "Outlook" on page 31 of the Company's 1999 Annual Report to Shareholders,
which  information  is  incorporated herein by reference from exhibit 13 to this
Form  10-K.
     Construction  Services'  business  is  seasonal  in  nature.  Most  of this
segment's  annual  profits  are  made   during  the   summer  and  fall  months.
Construction  Services  generally  incurs  losses  during the winter months when
underground  construction  is  inhibited.

ENGINEERING  SERVICES

The  Company's engineering services business segment ("Engineering Services") is
comprised  of  two  companies, Maverick Pipeline Services, Inc. ("Maverick") and
Oilfield Materials Consultants, Inc. ("OMC").  Maverick was acquired in December
1997  and  OMC was acquired in November 1998.  Maverick purchased the assets and
certain  liabilities  of  Drafting Services, Inc. in September 1999 and Pinpoint
Locators,  Inc.  in  October  1999.  These  two businesses are being operated as
divisions  of  Maverick.  See  Note 3 of the Notes to the Consolidated Financial
Statements  on  pages  49  through  51  of  the  Company's 1999 Annual Report to
Shareholders, which information is incorporated herein by reference from exhibit
13  to  this  Form  10-K,  for  information regarding acquisitions.  Engineering
Services has offices in New Jersey, Michigan, Louisiana and Texas and provides a
variety  of energy related engineering and quality assurance services in several
states.
     Engineering  Services  had  operating  revenues,  excluding  intercompany
transactions,  of  $14,841,000,  $40,937,000,  and  $5,660,000 in 1999, 1998 and
1997,  respectively.  These  operating  revenues accounted for 5%, 17% and 2% of
consolidated  operating revenues, excluding energy marketing operating revenues,
during  those  years.
     Engineering  Services serves the natural gas distribution and transmission,
oil  products,  exploration/production  and  telecommunication  industries.  The
primary  services  provided  include  engineering  design,  distribution  system
design,  construction  project  management,  field  surveys,  global positioning
surveys,  inspection, testing, pipeline-mill quality assurance and full turn-key
service.  Engineering  Services  competes  with  regional,  national  and
international  firms  as  well  as  in-house  engineering  and  field  service
departments.  Refer  to the section titled "Outlook" on page 32 of the Company's
1999  Annual Report to Shareholders, which information is incorporated herein by
reference  from  exhibit 13 to this Form 10-K, for further discussion concerning
competition  in  the  engineering  services  industry.
     There has been a reduction in oil and gas production and related activities
due  to  the downturn in oil prices in late 1998 and early 1999.  There has also
been  a  reduction  or  deferral  of  new  engineering  projects  for  the  gas
distribution  industry  due  to the cash flow impact on the industry of the warm
weather  during  the  past  two  years.  As  a  result, Engineering Services has
experienced a reduction in the level of available projects.  Management believes
that the level of available projects will increase as gas distribution companies
start  releasing  new  engineering  projects  and  as  pipeline construction and
inspection  projects  become available as a result of the recovery in oil prices
in  late  1999.


PROPANE,  PIPELINES  AND  STORAGE

The  Company's pipelines and storage operations consist of several pipelines and
a  gas  storage facility.  The Company has partial ownership interests or equity
interests  in certain of these operations.  The pipelines and storage operations
are  all  located  in  Michigan.  Refer  to  Item  2 of this Form 10-K, which is
incorporated  herein  by  reference, for additional information on each pipeline
and  storage  facility  such  as its location and customers.  In March 1998, the
Company  entered  the  propane  distribution  business  with  the acquisition of
Hotflame  Gas,  Inc.  and  Hotflame  Transport  Co.,  Inc.  (together  known  as
"Hotflame").  Hotflame  supplies  approximately  5  million  gallons  of propane
annually  to  retail  customers  in  Michigan's  upper  peninsula  and northeast
Wisconsin.  Because  propane  is  used  principally  for  heating,  most  of the
operating  income  for the propane business is generated in the first and fourth
quarters  of  the  calendar  year.
     The  retail  propane industry is highly fragmented with the largest firm in
the  industry serving less than 10% of the national market and the vast majority
of  propane  companies  individually  having less than one percent market share.
Propane  is  transported  easily  in pressurized containers and is generally the
fuel used in rural areas where natural gas pipelines and distribution systems do
not  exist  or are uneconomical to build.  The Company purchases the majority of
its propane from BP Amoco PLC.  The propane operation competes with other energy
sources  such  as  natural gas, fuel oil, electricity and other regional propane
providers.  The  basis  of  the  competition is generally price and service. The
propane  business has become increasingly competitive and less profitable, which
necessitates  large-scale  operations  to  be  successful in the long term.  The
Company  will continue to assess regional growth opportunities and the strategic
fit  of  the  propane  business  over  the  coming  year.

     The  Company  owns  a  50%  equity interest in the Eaton Rapids Gas Storage
System.  This system, located near Eaton Rapids, Michigan, became operational in
March  1990  and  consists  of  approximately  12.8  Bcf  of underground storage
capacity.  The  Gas  Distribution  Business  leases  6.5  Bcf  of  the capacity.
     The  Company  also  owns  50%  of  the  Michigan Intrastate Pipeline System
(MIPS")  and  the  Michigan  Intrastate  Lateral  System partnerships.  The sole
purpose  of  these  partnerships  is  to hold a 10% ownership of the Saginaw Bay
Pipeline  Project,  a  126-mile  pipeline  from  Michigan's  Saginaw Bay area to
processing  plants  in Kalkaska, Michigan.  The Company sold its MIPS investment
effective  January  1,  2000.
     The  property  of  the propane distribution operation consists primarily of
pressurized  propane  storage tanks used by customers to store propane purchased
from  the  Company  and  trucks for transporting propane.  The Company also owns
large  propane  storage  tanks  that  allow  the  Company to store up to 258,000
gallons  of propane inventory.  The propane distribution property is all located
in  Michigan's  upper  peninsula  and  northeast  Wisconsin.

                 SEMCO  ENERGY,  INC.  DEFERRED  COMPENSATION  PLAN

                                   ARTICLE  I

                                     PURPOSE

     The  purpose  of  the  SEMCO  Energy,  Inc.   Deferred   Compensation  Plan
(hereinafter  referred  to  as the "Plan") is to provide funds for retirement or
death  for  certain executive and management employees (and their beneficiaries)
of SEMCO Energy,  Inc.  It  is  intended that the Plan will aid in retaining and
attracting  employees  of exceptional ability by providing such employees with a
means  to  supplement  their  standard  of  living  at retirement.  This Plan is
intended  to qualify for the exemptions described in sections 201(2), 301(a)(3),
and  401(a)(1)  of  the  Employee  Retirement  Income  Security  Act of 1974, as
amended.

                                  ARTICLE  II

                                  DEFINITIONS

     For  the  purpose  of this Plan, the following words and phrases shall have
the  meanings  indicated,  unless  the  context  clearly  indicates  otherwise:

2.1     BENEFICIARY.   "Beneficiary"   means  the  person,  persons,  or  entity
designated  by  the  Participant, or as provided in Article VIII, to receive any
benefits  payable under the Plan.  Any Participant Beneficiary designation shall
be  made  in  a  written  instrument  filed  with the Committee and shall become
effective  only  when  received  in  writing  by  the  Committee.

2.2     BOARD.  "Board"  means  the  Board  of  Directors  of SEMCO Energy, Inc.

2.3     COMMITTEE.  "Committee"  means  the  Deferred  Compensation  Committee
appointed  by  the  Compensation  Committee  of  the  Board.

2.4     COMPANY.  "Company"  means  SEMCO  Energy,  Inc.,  and its subsidiaries.

2.5     COMPENSATION.  "Compensation"  or  "Total  Compensation"  means the Base
Salary and Incentive Compensation payable to a Participant during the Plan Year.

     (a)     BASE  SALARY.  "Base  Salary"  means  all  regular remuneration for
services,  other  than  such  items  as  Incentive  Compensation, payable by the
Company  to  a  Participant in cash during a Plan Year, but before reduction for
amounts  deferred  pursuant  to this Plan or any other Plan of the Company.  The
Committee  shall determine whether a particular item of income consti-tutes Base
Salary  if  a  question  arises.

     (b)     INCENTIVE  COMPENSATION.  "Incentive  Compensation"  means any cash
bonus  paid  to  a  Participant  in  a  Plan  Year.

<PAGE>

2.6     DECLARED  RATE.  "Declared  Rate" means the rate of interest or earnings
(positive  or  negative)  to  be credited to the Participant's deferral account.
The  participant  shall choose, and indicate in his Participation Agreement, one
of  the  four  following  investment indexes prior to the beginning of each Plan
Year,  and  his  deferral  account  shall  be credited with interest or earnings
(positive  or  negative)  based  on  that  index  for  the subsequent Plan Year.

(a)     Choice One:  S&P 500 RETURN INDEX.  A monthly return equal to the return
of the Standard & Poors 500 stock index, including dividends, for the applicable
month  as  published  by Callan Associates or other such source as determined by
the  Committee.

(b)     Choice  Two:  STABLE VALUE RETURN INDEX.  A monthly return equal to 115%
of the return on short-term Treasury Bills for the applicable month as published
by  Callan  Associates  or  other  such  source  as determined by the Committee.

(c)     Choice Three:  BALANCED RETURN INDEX.  A monthly return derived from the
simple  average of (1) the S&P 500 Return Index, and (2) the Stable Value Return
Index.

(d)     Choice  Four:  SEMCO PHANTOM STOCK INDEX. This "Index" is much different
from  the above 3 indices because earnings or losses in this Phantom Stock Index
are  based  on  the return that an investor would receive by purchasing only one
kind  of  stock:  being  Common  Stock  of  SEMCO  Energy,  Inc.

Actual  shares  of  Common Stock are not purchased. Instead, earnings and losses
are  determined  as  though  all deferred Compensation credited to your deferral
account  were  used  to  purchase  Common  Stock  at  the price, at the time and
otherwise  in the manner consistent with the Company's Direct Stock Purchase and
Dividend  Reinvestment  Plan  ("DRIP").  This phantom purchase will occur at the
earliest  DRIP  investment  date  after  the amount is credited to your account.
Thus,  your  account  will  be  invested  in  "Phantom  Stock".

Further,  your  deferral  account  will  be  credited  with additional shares of
Phantom  Stock  at  the time and otherwise in the manner that an equal number of
actual  shares of Common Stock would be credited to your account if your account
held  actual  Common  Stock  reinvesting  dividends  in  the  DRIP.

2.7     DEFERRAL  BENEFIT.  "Deferral  Benefit"  means  the benefit payable to a
Participant  or  Participant's  Beneficiary  on Participant's retirement, death,
disability,  or  termination  of employment as calculated in Article VII hereof.

2.8     DEFERRED BENEFIT ACCOUNT.  "Deferred Benefit Account" means the accounts
maintained  on the books of account of the Company for each Participant pursuant
to Article VI.  A separate Deferred Benefit Account shall be maintained for each
Participant.  A  Participant's Deferred Benefit Account shall be utilized solely
as  a  device for the measurement and determination of the amounts to be paid to
the  Participant pursuant to the Plan.  A Participant's Deferred Benefit Account
shall  not  constitute  or  be  treated  as  a  trust  fund  of  any  kind.

2.9     DETERMINATION DATE.  "Determination Date" means the date as of which the
amount  of a Participant's Deferred Benefit Account is determined as provided in
Article VI hereof.  The last day of each calendar month shall be a Determination
Date.

2.10     DISABILITY.  "Disability" or "Disabled Participant" means a physical or
mental condition of a Participant resulting in a determination of disability for
purposes  of  receiving  benefits under the Company's Long Term Disability Plan.

2.11     PARTICIPANT.  "Participant" means any individual who is deemed eligible
by  the  Committee  to participate in this Plan and who elects to participate by
filing  a  Participation  Agreement  as  provided  in  Article  IV.

2.12     PARTICIPATION AGREEMENT.  "Participation Agreement" means the agreement
filed  by a Participant prior to the beginning of the first period for which any
of  the  Participant's  Compensation  is to be deferred pursuant to the Plan.  A
form  of  such  Participation  Agreement  is  attached  hereto.

2.13     PLAN  YEAR.  "Plan Year" means a twelve month period commencing January
1  and  ending the following December 31.  The first Plan Year shall commence on
October  1,  1999  and  terminate  on  December  31,  1999.

2.14     RETIREMENT  DATE.  "Retirement  Date"  means the first day of the month
coincidental  with or next following a Participant's actual retirement under the
SEMCO  Energy,  Inc.  Non-Union  Retirement  Plan.

2.15     SPOUSE.  "Spouse"  means  a  Participant's  wife  or  husband  who  was
lawfully  married to the Participant at the time of the Participant's death or a
determination  of  Participant's  incompetency  under  paragraph  10.8.


                                    ARTICLE  III

                                   ADMINISTRATION

3.1     DEFERRED  COMPENSATION  COMMITTEE:  DUTIES.  This  plan  shall  be
administered  by  the  Committee.  Members  of the Committee may be Participants
under  this  Plan.  The  Committee shall also have the authority to make, amend,
interpret,  and  enforce  all  appropriate  rules  and  regulations  for  the
administration  of  this  Plan  and  decide  or  resolve  any and all questions,
including interpretation of this Plan, as may arise in connection with the Plan.

3.2     BINDING  EFFECT  OF  DECISION.  The  decision or action of the Committee
with  respect  to  any  question  arising  out  of  or  in  connection  with the
administration,  interpretation,  and  application of the Plan and the rules and
regulations  promulgated  hereunder shall be final, conclusive, and binding upon
all persons having any interest in the Plan, unless a written appeal is received
by  the  Committee within sixty days of the disputed action.  The appeal will be
reviewed  by  the  Committee  and  the decision of the Committee shall be final,
conclusive, and binding on the Participant and all persons claiming by, through,
or  under  the  Participant.


                                   ARTICLE  IV

                                  PARTICIPATION

4.1     PARTICIPATION.  Participation  in the Plan shall be limited to the class
of those key employees selected by the Committee who elect to participate in the
Plan  by  filing  a Participation Agreement with the Committee.  A Participation
Agreement must be filed prior to December 15 immediately preceding the Plan Year
in  which  the  Participant's  participation  under the Agreement will commence;
provided, however, that the Committee may establish a later date in December for
filing  a  Participation  Agreement  when a change to the form of that Agreement
makes  a later date appropriate.  The election to participate shall be effective
on  the  first  day  of  the  Plan  Year following receipt by the Committee of a
properly  completed  and  executed  Participation  Agreement.

     With  respect  to  the  first  Plan  Year of the Plan or with respect to an
individual  hired or promoted during a Plan Year who thereby becomes eligible to
participate  herein,  an  initial  Participation  Agreement  may be filed within
thirty  days  of  the  Committee's notification to Participant of eligibility to
participate.  Such  election  to  participate shall be effective no earlier than
the  first  day  of  the  pay  period following the Committee's receipt thereof.

4.2     MINIMUM AND MAXIMUM DEFERRAL AND LENGTH OF PARTICIPATION.  A Participant
may  elect in a Participation Agreement to defer a portion of Participant's Base
Salary  or  Incentive Compensation.  The minimum and maximum amounts that may be
deferred  under  a  Participa-tion  Agreement  shall  be  as  follows:

                                   Minimum  Deferral          Maximum  Deferral
                                   -----------------          -----------------

     With respect to Base          2% of Base Salary          50% of Base Salary
     Salary  Deferrals

     With  respect  to             25% of Incentive           100% of Incentive
     Incentive  Compensation       Compensation               Compensation

     (a)     With  respect  to  Base  Salary  deferrals, the deferral percentage
elected  in a Participation Agreement shall be applied to the Participant's Base
Salary  as  established  for  the first pay period of the Plan Year to which the
Participation  Agreement  applies,  and the resulting dollar amount shall be the
amount  of  Base  Salary  that will be deferred in each pay period over the Plan
Year.

          Deferrals  shall commence with the Plan Year immediately following the
Plan  Year  in  which the respective Participation Agreement is filed; provided,
however,  that  an initial Participation Agreement which is effective other than
on January 1 of a Plan Year shall apply to the remainder of the Plan Year and to
the  following  Plan  Year  as  set  forth  above.

     (b)     With  respect  to  Incentive  Compensation  deferrals, the deferral
percentage  selected  in  a  Participation  Agreement  shall  apply  to  the
Participant's  Incentive  Compensation  to  be paid in the Plan Year immediately
following  receipt  of  the  Participation  Agreement.

     (c)     A Participant's election to defer Compensation shall be irrevocable
upon  the  filing  of the respective Participation Agreement; provided, however,
that  the  deferral  of  Compensation  under  any Participation Agreement may be
suspended  or  amended  as  provided  in paragraphs 7.4, 7.8, 9.1, or as further
described  in  this  paragraph.

4.3     ADDITIONAL  PARTICIPATION AGREEMENT.  A Participant may enter into a new
Participation  Agreement  by filing a Participation Agreement with the Committee
prior  to  December  15  of  any  calendar  year,  stating  the  amount that the
Participant  elects to have deferred.  The new agreement shall be effective only
as  to  Compensation paid in Plan Years beginning after the last day of the Plan
Year  in  which  the  respective  agreement  is filed with the Committee.  A new
Participation Agreement is subject to all of the provisions and requirements set
forth  in  paragraph  4.2.


                                    ARTICLE  V

                              DEFERRED  COMPENSATION

5.1     ELECTIVE  DEFERRED  COMPENSATION.  The  amount  of  Compensation  that a
Participant  elects  to  defer  in  a  Participation  Agreement  executed by the
Participant with respect to each Plan Year of participation in the Plan shall be
credited by the Company to the Participant's Deferred Benefit Account throughout
each  Plan  Year  as  the  Participant  is  paid  the  non-deferred  portion  of
Compensation  for  such  Plan  Year.  The  amount  credited  to  a Participant's
Deferred  Benefit  Account  shall equal the amount deferred.  To the extent that
the  Company  is  required  to  withhold  any  taxes  or  other  amounts from an
employee's  deferred  wages  pursuant  to any state, federal, or local law, such
amounts  shall  be  taken  out  of  the Participant's Compensation which is not
deferred  under  this  Plan.

5.2     EFFECT  ON  OTHER  PLANS.  To  the  extent  to  which  deferrals  by  a
Participant  under  this  Plan  cause  a  reduction  in  pension  benefits for a
Participant  under  the SEMCO, Inc. Non-Union Retirement Plan, the Company shall
provide  supplementary  benefits to the extent of such reduction.  The amount of
such  reduction  shall  be  determined,  as  of  the  time  of the Participant's
termination  of  employment  or  retirement  under said Retirement Plan, by said
Plan's  administrator  based upon the form of pension benefit applicable to such
Participant,  which  determination  shall  be  binding  and  conclusive  on such
participant.

     To  the  extent to which deferrals by a Participant under this Plan cause a
reduction  in  matching  contributions  made  by  the  Company  on behalf of the
Participant  under  the SEMCO Energy, Inc. 401(k) Plan, the Company shall credit
the  amount  of any such reduction to the Participant's Deferred Benefit Account
under  this Plan. Such amount will be credited as of the December 31 of the year
in  which  such  reduction  of  contributions  occurs,  or  upon  termination of
employment,  if  earlier.

     The  Company shall compute life insurance and disability benefits under any
Company  plan based on Compensation without reduction for amounts deferred under
this  Plan.

5.3     Vesting of Deferred Benefit Account.  A Participant shall be 100% vested
in  the  Participant's  Deferred  Benefit  Account.


                                   ARTICLE  VI

                            DEFERRED  BENEFIT  ACCOUNT

6.1     DETERMINATION  OF  ACCOUNT.  Each Participant's Deferred Benefit Account
as  of  each  Determination  Date  shall  consist  of  (1)  the  balance  of the
Participant's  Deferred  Benefit  Account  as  of  the  immediately  preceding
Determination  Date,  plus  (2) the Participant's elective deferred Compensation
withheld  since  the  immediately  preceding  Determination  Date  pursuant  to
paragraph  5.1, less (3) the amount of all distributions, if any, made from such
Deferred  Benefit  Account since the preceding Determination Date, plus or minus
(4)  any interest or earnings adjustment as determined under paragraph 6.2, plus
(5)  a  credit  for  any reduced 401(k) plan matching contributions as described
under paragraph 5.2.  In addition, the amount of any benefits foregone under the
Retirement  Plan  as  described  in  paragraph  5.2  shall  also  be included in
determining  the  value  of  the  Deferred  Benefit  Account upon termination of
employment.

6.2     CREDITING  OF ACCOUNT.  As of each Determination Date, the Participant's
Deferred Benefit Account shall be adjusted by the amount of interest or earnings
computed since the preceding Determination Date.  This adjustment shall be based
on  the  Declared  Rate  as  defined  in  paragraph  2.6  or as determined under
paragraph  7.5(a)(2)  as applicable.   Any such adjustment shall be based on the
average of the month end and month beginning balances excluding this adjustment.

6.3     STATEMENT  OF  ACCOUNTS.  The  Company shall submit to each Participant,
within  120  days after the close of each Plan Year, a statement in such form as
the  Company  deems  desirable,  setting forth the balance to the credit of each
Participant's  Deferred  Benefit  Account  as of the last day of such Plan Year.


                                 ARTICLE  VII

                                   BENEFITS

7.1     BENEFIT  FOR  RETIREMENT  OR  TERMINATION  OF  EMPLOYMENT.  Subject  to
paragraph  7.6  below,  upon  a  Participant's  retirement  after  reaching  the
Retirement  Date,  or any termination of employment for reasons other than death
or  disability, the Participant shall be entitled to a Deferral Benefit equal to
the amount of Participant's Deferred Benefit Account determined under paragraphs
6.1 and 6.2 hereof as of the Determination Date coincidental with or immediately
following  such  event.

7.2     DEATH.  Upon  the death of a Participant, such Participant's Beneficiary
shall  receive  a  Deferral  Benefit  equal  to  the  remaining  balance in such
Participant's  Deferred  Benefit  Account.

     The  Deferral Benefit shall be payable as provided for in paragraph 7.5(a).

     The  Deferral Benefit provided above shall be in lieu of all other benefits
under  this  Plan.

7.3     DISABILITY.  In  the  event of Disability, as defined in paragraph 2.10,
while  employed  by  the Company, payments shall commence upon attainment of the
Participant's  Normal  Retirement  Date  in  the  form  specified  in  paragraph
7.5(a)(2)  over  a  period from 2 to 360 months.  Before payments commence under
the  preceding  sentence,  a  Disabled Participant may elect:  (i) to accelerate
commencement  of  the payments until the date not earlier than 60 days after the
onset  of  Disability, and/or (ii) to change the form of payment to another form
permitted  under  paragraph  7.5(a).

7.4     SUSPENSION  OF  PARTICIPATION/DISTRIBUTION/FAILURE  TO  CONTINUE
PARTICIPATION.  The  Committee, in its sole discretion, may suspend the deferral
of a Participant's Base Salary during a Plan Year, and may also authorize a lump
sum  distribution  from  the  Participant's  Deferred  Benefit Account, upon the
advance  written  request  of  a  Participant  on  account of financial hardship
suffered  by  that  Participant.  A  Participant  must file any request for such
suspension  or  distribution  on  or  before  the 15th day preceding the regular
payday  on  which  the  suspension or distribution is to take effect.  Incentive
Compensation  deferrals  may  not  be  suspended  during  the  Plan  Year.

     Financial  hardship  shall  mean an unexpected need for cash resulting from
conditions  in  the  nature  of  any  of  the  following:

     (a)     An  accident, illness, or disability suffered by a Participant or a
family  member  or  dependent;

     (b)     A  casualty  or  theft  loss  suffered by a Participant or a family
member  or  dependent;

     (c)     The  rendering  of  a  judgment  against  a Participant or a family
member  or  dependent;

     (d)     A sudden financial reversal or curtailment of income experienced by
a  Participant  or  a  family  member  or  dependent;  or,

     (e)     The  transfer  of  a  Participant's  place  of  employment.

     The  suspension  of  any  deferrals  under  this paragraph shall not affect
amounts  deferred  with  respect  to  periods prior to the effective date of the
suspension  except  as  otherwise  permitted  by  the  Committee.

     In  the  event  the  Participant  ceases to remain a member of the class of
employees who are eligible to participate in the Plan, the Participant may elect
to suspend the amount of any remaining deferral commitment in the same manner as
described for other suspensions in the paragraph, except that Committee approval
shall  not  be  required.

7.5     FORM  OF  BENEFIT  PAYMENT.

     (a)     Upon  retirement,  death, or termination of employment, the Company
shall  pay  to  the  Participant or Participant's Beneficiary the balance in the
Participant's Deferred Benefit Account in one of the following forms, as elected
in  the  Participation  Agreement  filed  by  the  Participant:

          (1)     A  lump  sum  payment.

          (2)     A  monthly  payment of a fixed amount which shall amortize the
Deferred  Benefit  Account  balance  in  equal monthly payments of principal and
interest  over  a  period from 2 to 360 months.  For purposes of determining the
amount  of the monthly payment, the rate of interest shall be the average of the
Stable  Value  Return  Index for the shorter of (i) the last five (5) Plan Years
preceding  the initial monthly installment payment, or (ii) the actual number of
Plan  Years  of  participation  by  the  Participant.

     (b)     A  Participant  may change the form in which benefits shall be paid
by filing a new Participation Agreement indicating such change any time prior to
the  date  payments  are  to commence.  Such new Participation Agreement may not
change  the  provisions  of  any  previous  Participation  Agreement to which it
related  for purposes of complying with the provisions of paragraphs 4.2 and 4.3
relating  to the minimum and maximum deferrals and duration of the Participation
Agreement.  No  such new Participation Agreement shall change the amount elected
to  be  deferred  in  a  prior  Participation  Agreement.

     (c)     In  the  absence  of  a  Participant's  election under subparagraph
7.5(a),  benefits  shall be paid in the form specified in subparagraph 7.5(a)(2)
over  a 180-month period.  In the event of a Disabled Participant, payment shall
be  in  the  form  described  in  paragraph  7.3.

7.6     WITHHOLDING:  PAYROLL  TAXES.  To  the  extent  required  by  the law in
effect  at  the time payments are made, the Company shall withhold from payments
made  hereunder  any taxes required to be withheld from any employee's wages for
the  federal  or  any  state  or  local  government.

7.7     COMMENCEMENT  OF  PAYMENTS.  Commencement  of  payments  under this Plan
shall  begin  within  sixty days following receipt of notice by the Committee of
any event which entitles a Participant (or a Beneficiary) to payments under this
Plan, or at such earlier date as may be determined by the Company.  All payments
shall  be  made  as  of  the  first  day  of  the  month.

7.8     EARLY  DISTRIBUTION  OF  DEFERRED  ACCOUNT  BALANCE.  A  participant who
remains  employed  by  the Company may elect to receive a distribution of all or
any  part  of  the  Participant's  Account  Balance  prior  to  the  date(s)  of
distribution  specified  in  the Participant's Participation Agreement(s).  Each
Participant  shall  be limited to one such distribution per calendar year.  Such
election, however, will involve a substantial penalty, as each such distribution
from  the Participant's Deferred Benefit Account made under this provision shall
be  reduced  by  a  penalty equal to six percent (6%) of the total amount of the
distribution.  The  amount of the penalty shall be forfeited by the Participant.
In  addition,  the Participant must continue to defer Compensation subsequent to
such  withdrawal  in  accordance with the Participant's election and will not be
permitted  to  elect  to  defer  Compensation  attributable to the calendar year
subsequent  to  the  calendar  year  of  the  distribution.


                                  ARTICLE  VIII

                             BENEFICIARY  DESIGNATION

8.1     BENEFICIARY  DESIGNATION.  Each Participant shall have the right, at any
time,  to  designate any person or persons as Beneficiary or Beneficiaries (both
principal  as  well as contingent) to whom payment under this Plan shall be made
in  the  event  of  Participant's  death  prior  to complete distribution of the
benefits  due  to the Participant under the Plan.  In any beneficiary dies while
receiving  payments,  the  remaining  value of future payments will be paid in a
lump  sum  to  the  decedent's  estate.

8.2     AMENDMENTS.  Any Beneficiary designation may be changed by a Participant
by the written filing of such change on a form prescribed by the Committee.  The
filing  of  a  new  Beneficiary  Designation  form  will  cancel all Beneficiary
designations  previously  filed.

8.3     NO  BENEFICIARY  DESIGNATION.  If  a  Participant  fails  to designate a
Beneficiary as provided above, or if all designated Beneficiaries predecease the
participant, then the Participant's designated Beneficiary shall be deemed to be
the  surviving  Spouse.  Otherwise, the value of the Participant's account shall
be  paid as a lump sum to the Participant's personal representative (executor or
administrator).

8.4     EFFECT  OF  PAYMENT.  The  payment  to  the  deemed  Beneficiary  shall
completely  discharge  the  Company's  obligations  under  this  Plan.


                                  ARTICLE  IX

                     AMENDMENT  AND  TERMINATION  OF  PLAN

9.1     AMENDMENT.  The  Board  may  at  any  time amend the Plan in whole or in
part;  provided,  however,  that  no amendment shall be effective to decrease or
restrict  any  Deferred  Benefit Account at the time of such amendment or reduce
any  additional benefits provided under paragraph 5.2.  In the event the Plan is
amended,  the Participation Agreement shall be subject to the provisions of such
amendment  as  if set forth in full therein, without further action or amendment
to  the  Participation  Agreement.  The  parties shall be bound by, and have the
benefit  of, each and every provision of the Plan, as amended from time to time.

9.2     COMPANY'S  RIGHT  TO TERMINATE.  The Board may at any time terminate the
Plan with respect to new elections to defer if, in its judgment, the continuance
of  the  Plan,  the  tax,  accounting,  or  other  effects thereof, or potential
payments  thereunder  would  not  be  in the best interests of the Company.  The
Board may also terminate the Plan in its entirety at any time, and upon any such
termination,  all Participants under the Plan shall be paid the balance in their
Deferred  Benefit  Accounts  in  a  lump  sum,  or  over  such period of time as
determined  by  the  Board.

9.3     PREMATURE  PLAN TERMINATIONS AND PREMATURE DISTRIBUTIONS.  The Committee
shall  have  the  right  (but  shall not be obligated) to require premature Plan
termination  and  premature  Plan  distributions to Participants, as outlined in
paragraph 9.2, upon the occurrence of any of the following conditions or events:

     (a)     If  any  rating  on any debt securities of the Company, as rated by
Moody's  or  Standard & Poor's, is downgraded to a rating lower than that rating
as  of  the  date  of  this  Plan;

     (b)     If  the  shareholders  of  the  Company  approve  the  merger  or
consolidation  of  the  Company with or into any other corporation (other than a
corporation  wholly-owned by the Company immediately prior to such event) or the
acquisition of substantially all of the business or assets of the Company by any
other  person  or  entity  (other than a corporation wholly-owned by the Company
immediately  prior  to  such  event);

     (c)     If a change occurs in the Board of Directors of the Company whereby
Directors  comprising  a majority of the Board of Directors immediately prior to
such  change  do not continue to comprise such a majority immediately after such
change,  provided  that  incremental  and/or  related changes (including but not
limited  to  resignations  from  the  Board  of  Directors) which occur within a
relatively  brief  period  of time shall be considered to be but a single change
for  purposes  of  this  Subparagraph;

     (d)     If,  as  a  result  of any tender offer or otherwise, any person or
entity  or  affiliated group becomes the beneficial or record owner of more than
10%  of  the  outstanding  voting  securities  of  the  Company;  or

     (e)     If,  in  the  Board's  sole  judgment  and  discretion, a change in
circumstances  has  occurred  (including but not limited to a change in taxation
laws  or regulations, securities laws or regulations, accounting requirements or
the  events in Subparagraphs (a), (b), (c), and (d) of this Paragraph 9.3) which
causes  the Plan to be undesirable to a significant portion of the Participants.

                                   ARTICLE  X

                                 MISCELLANEOUS

10.1     UNSECURED GENERAL CREDITOR.  Participants and their Beneficiaries shall
have no legal or equitable rights, interest, or claims in any property or assets
of  the Company. The Company's obligation under the Plan shall be merely that of
an  unfunded  and  unsecured  promise of the Company to pay money in the future.

10.2     NON-ASSIGNABILITY.  Neither  a  Participant  nor any other person shall
have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage,
or  otherwise  encumber,  transfer,  hypothecate, or convey in advance of actual
receipt  the amounts, if any, payable hereunder, or any part thereof, which are,
and  all  rights  to  which  are,  expressly  declared  to  be  unassignable and
non-transferable.  No  part  of  the  amounts  payable  shall,  prior  to actual
payment,  be  subject  to seizure or sequestration for the payment of any debts,
judgments,  alimony,  or separate maintenance owed by a Participant or any other
person,  nor be transferable by operation of law in the event of a Participant's
or  any  other  person's  bankruptcy  or  insolvency.

10.3     NOT  A  CONTRACT  OF EMPLOYMENT.  The terms and conditions of this Plan
shall  not  be deemed to constitute a contract of employment between the Company
and  the  Participant,  and the Participant (or Participant's Beneficiary) shall
have  no  rights  against  the  Company  except as may otherwise be specifically
provided  herein.  Moreover,  nothing  in  this  Plan  shall be deemed to give a
Participant  the  right  to  be  retained  in  the  service of the Company or to
interfere  with  the right of the Company to discipline or discharge Participant
at  any  time.

10.4     PROTECTIVE  PROVISIONS.  A  Participant will cooperate with the Company
by  furnishing  any  and  all  information  requested by the Company in order to
facilitate  the  payment  of  benefits  hereunder.

10.5     GOVERNING  LAW.  The  provisions  of  this  Plan shall be construed and
interpreted  according  to  the  laws  of  the  State  of  Michigan.

10.6     SUCCESSORS.  The  provisions  of  this Plan shall bind and inure to the
benefit  of  the  Company  and  its  successors  and  assigns.

10.7     EFFECTIVE  DATE.  This  Plan  shall  become  effective as of October 1,
1999.

10.8     INCOMPETENT.  In  the  event  that  it  shall  be  found  upon evidence
satisfactory  to  the  Committee  that  any Participant or Beneficiary to whom a
benefit  is  payable under this Plan is unable to care for such Participant's or
such  Beneficiary's  affairs  because  of  illness  or accident, any payment due
(unless  prior claim therefor shall have been made by a duly authorized guardian
or  other legal representative) may be paid, upon appropriate indemnification of
the  Company,  to  the  Spouse  or  other person deemed by the Committee to have
incurred  any  expense  for such Participant or a Beneficiary.  Any such payment
shall be a payment for the account of the Participant or a Beneficiary and shall
be  a  complete  discharge  of  any  liability  of  the  Company  therefor.

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


RESULTS  OF  OPERATIONS

NET  INCOME - SEMCO  Energy,  Inc.  and  its  subsidiaries  (the  "Company") had
consolidated  net  income  of  $17.7 million (or $1.00 per share) in 1999, $10.0
million  (or  $0.63 per share) in 1998 and $15.4 million (or $1.06 per share) in
1997.  Warmer  than  normal  weather had a significant impact on earnings during
1999  and  1998.  On  a  weather-normalized  basis,  net  income would have been
approximately  $21.3  million in 1999 compared to approximately $17.2 million in
1998.
     The  following  table  shows  the impact of warmer than normal weather, the
divestiture  of  the  energy  marketing  business,  the divestiture of the NOARK
investment,  a  change  in  accounting method and an extraordinary charge on net
income  and  earnings  per  share  for  the  past  three  years.

(a)     The Company determines the impact of weather on its operating results by
comparing  actual  gas  usage  per  customer  during  a  year  to the average of
weather-normalized  customer  gas  usage  during  previous  years.  The
weather-normalized customer gas usage is determined by adjusting actual customer
gas  usage  during  a  particular  year by a ratio, the numerator of which is an
average  of  degree  days during the prior fifteen years, and the denominator of
which  is  the  actual  degree  days  for  that year. The Company determines the
percent  (%)  that weather is warmer or colder than normal for a particular year
by  computing the deviation of actual degree days for that year from the average
of degree days during the prior fifteen years and dividing the deviation by such
fifteen  year  average.

     Also,  the  1999  results  include approximately $2.6 million of net income
from ENSTAR Natural Gas Company and Alaska Pipeline Company, which were acquired
on  November  1,  1999.  The business segment analyses on the next several pages
provide additional information regarding the variances in operating results when
comparing  1999,  1998  and  1997.

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").  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

Page 24

SEMCO  Energy,  Inc.  and  Subsidiaries



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 $170 million of medium-term
notes,  $35  million of trust preferred securities and approximately 7.1 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.

SUMMARY  OF  BUSINESS  SEGMENTS

The  Company operates four business segments: (1) gas distribution; (2) pipeline
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
pipeline  construction  services  segment  currently  does  business  in  the
mid-western  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.

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


     The  previous  table  shows  the operating revenues and operating income of
each business segment 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 intercompany eliminations, corporate
related expenses not allocated to the business segments and the results of other
smaller  operations.
     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".
     The operating income of the Gas Distribution Business increased in 1999 due
primarily  to  the  impact  of  cooler weather in 1999 when compared to 1998 and
operating  income  attributable  to  ENSTAR. Weather was approximately 7% warmer
than normal in 1999 compared to approximately 20% warmer than normal in 1998. On
a  weather-normalized  basis,  the  operating  income  of  the  Gas Distribution
Business  would  have increased by $12.3 million in 1999 compared to 1998 and by
$6.8  million  in 1998 when compared to 1997.  Approximately $7.9 million of the
$12.3 million increase in weather-normalized operating income in 1999 represents
the weather-normalized operating income of ENSTAR for the months of November and
December  1999.

</TABLE>

GAS SALES MARGIN - In 1999, gas sales margin increased by $16.1 million (or 28%)
when compared to 1998. $11.6 million of the increase was attributable to ENSTAR.
The  remainder  of the increase was due primarily to sales margins from the sale
of  gas under a new third-party gas supply and storage arrangement, a portion of
which  may  be  non-recurring,  and to additional gas sales, which resulted from
cooler weather and the addition of new customers, offset partially by a decrease
in  gas  sales  margin of approximately $4.2 million due primarily to a shift in
customers  to transportation as a result of a multi-location aggregation program
offered  to  Michigan  customers.
     The  third-party gas supply and storage arrangement is with TransCanada Gas
Services,  Inc.  ("TransCanada")  and  pertains  to  the  Michigan-based  gas
distribution  operations.  Under  this  agreement,  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. Also effective April 1, 1999,
the Michigan-based operation reduced and froze in its base rates a gas charge of
$3.24  per  thousand  cubic  feet  ("Mcf")  and  suspended  its

Page 26

<PAGE>
SEMCO  Energy,  Inc.  and  Subsidiaries



gas  cost recovery ("GCR") clause for a period of three years as authorized in a
September  1998  Michigan  Public  Service  Commission ("MPSC") order. Under the
terms  of  the  TransCanada  agreements, the Company's gas costs are fixed at an
amount  below  the  $3.24  per Mcf. As a result of suspending the GCR clause and
contractually  fixing  the cost of gas below the $3.24 charged to customers, the
Michigan gas distribution operation retains the sales margin on the sale of gas,
subject  to a customer profit sharing mechanism also approved in the MPSC order.
Prior to the suspension of the GCR clause on April 1, 1999, gas sales margin was
generated  primarily  from  distribution  and customer fees because the Michigan
operation  was  not  allowed to earn profits from the sale of the gas commodity.
See  Note 2 in the Notes to the Consolidated Financial Statements for additional
information  on  the  MPSC  order and the gas supply management arrangement with
TransCanada.
     The  aggregation  tariff,  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. The program
is  referred  to  as  the  aggregated  transportation  service  ("ATS") program.
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 now acting as a transporter for those
customers.
     The  addition  of  new  customers in Michigan increased gas sales margin by
approximately $1.5 million in 1999, when compared to 1998. The Company's average
number  of  gas  sales  customers  increased by 17,336 in 1999. A portion of the
increase  was due to the addition of an average of 6,363 new gas sales customers
in  Michigan,  offset  partially  by an average of 5,932 gas sales customers who
switched  from  gas  sales  service  to  the  ATS  program. The remainder of the
increase  relates  to  owning  ENSTAR  for  two  months  in  1999.
     Gas  sales  margin  in  1998 decreased by $9.9 million (or 15%) compared to
1997.  This was due primarily to lower gas sales resulting from the unseasonably
warm  weather  during 1998 and customers switching from gas sales service to the
ATS  program,  offset partially by the addition of new gas sales customers and a
rate  increase  in  October  1997. The weather during 1998 was approximately 20%
warmer  than  normal.  $10.8  million  of  the  decrease  in gas sales margin is
attributable  to  the  warm  temperatures  and  $2.5  million of the decrease is
attributable  to  customers  switching  to  the ATS program. The addition of new
customers  increased  gas  sales  margin  by  $1.8  million  in  1998.  The  Gas
Distribution Business added an average of 7,359 new gas sales customers in 1998.
During  the  same  period, an average of 2,900 gas sales customers switched from
gas  sales  service  to  the  ATS  program.
     The  October  1997 rate increase referred to above was granted primarily to
allow  for  the  recovery of costs related to a change in accounting for retiree
medical  benefits.  The  rate increase was approved in the October 1997 Order of
the  MPSC  ("1997  rate  case")  (see  Note  2  in the Notes to the Consolidated
Financial  Statements).

GAS  TRANSPORTATION  REVENUE - The  gas  transportation  revenue  of  the  Gas
Distribution  Business  increased by $7.5 million in 1999 when compared to 1998.
$4.2  million of the increase is due to revenues from customers participating in
the  ATS  program  as  discussed  previously  and  the remainder is attributable
primarily  to gas transportation revenues of ENSTAR. In 1998, gas transportation
revenue  increased  by  $1.6  million  when  compared  to 1997, due primarily to
revenues  of approximately $2.5 million from the ATS program offset partially by
lower  off-peak  Michigan  transportation  rates approved in the 1997 rate case.

OTHER  OPERATING  REVENUE - During  1999  and  1998,  other  operating  revenue
increased  by  $.6  million and $1.6 million, respectively, over the prior year.
The  increase  is  due primarily to an increase in balancing charges and various
miscellaneous  fees  charged  to  customers.

OPERATING  EXPENSES - In  1999,  the  operating expenses of the Gas Distribution
Business  increased  by $6.4 million (or 12.3%) when compared to 1998. Operating
expenses  attributable  to  ENSTAR for November and December of 1999 account for
$6.0  million of the increase. The operating expenses of the Michigan operations
increased  by  $.4  million  (or  less  than  1%)  when  compared  to  1998.
     The  $.4  million  increase  in  the  Michigan  operation's  1999 operating
expenses  includes a number of offsetting increases and decreases. The decreases
include  approximately  $1.0  million  attributable  to  an overall reduction in
general  and  administrative  expenses  due  to cost cutting measures undertaken
during  the  past  year  and  reductions  in  compensation  and employee benefit
expenses  due  primarily  to lower employee levels as a result of the 1998 early
retirement program and changes to the Company's employee benefit plans. See Note
9  in the Notes to the Consolidated Financial Statements for more information on
the  early  retirement  program.  The  decreases  also include approximately $.4
million  due  to  lower uncollectible gas accounts and approximately $.4 million
relating  to  general  taxes.  The  decrease  in  general  taxes is made up of a
reduction  of  $1.3  million in property taxes 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. Approximately 38% of the $1.3 million
reduction  in  property tax expense relates to taxes expensed in prior years and
the  remainder  relates  to  1999.
     The  above  decreases  in operating expenses of the Michigan operation were
offset  by  a  number  of  increases.  Information technology expense, primarily
year-2000  (or  "Y2K")  computer remediation, increased in 1999 when compared to
1998  by  approximately  $1.0  million  and  incentive compensation increased by
approximately  $.4  million due primarily to lower incentive compensation in the
prior  year  as  a  result  of lower Company earnings. Depreciation expense also
increased  in  1999 by $.8 million as a result of additional property, plant and
equipment  placed  in  service.
     The Gas Distribution Business' operating expenses decreased by $2.7 million
(or  5%)  in  1998  when  compared  to  1997.  Approximately $1.9 million of the
decrease  is  attributable to an overall reduction in general and administrative
expenses  due  to  cost cutting measures undertaken during 1998, lower incentive
compensation  due  to  the  decrease  in  Company  earnings,  and  reductions in
compensation  and  pension  expenses due primarily to lower employee levels as a
result  of  the

Company's early retirement program and changes to the Company's employee pension
plans.  The  remainder  of  the  decrease  was  due  to  lower uncollectible gas
accounts,  regulatory  expenses,  insurance  costs  and  a one-time reduction in
employee  benefit  expenses  related  to  the  early  retirement program, offset
partially  by  an  increase in depreciation expense as a result of new property,
plant  and  equipment  placed  in  service  and  an  increase in retiree medical
expense.  The  1997  rate case authorized a customer rate increase to offset the
impact  of  the  additional  retiree  medical  expense.

OUTLOOK - The  Company's  strategy  for  its  Gas  Distribution  Business  is to
increase  its  earnings  potential  and  expand  through  market  growth  and
acquisitions  that  are  expected by the Company to provide incremental revenue,
cost  synergies  and  additional  business  opportunities.  In 1999, the Company
acquired  ENSTAR  pursuant  to  this  strategy. Management is evaluating ways to
offer  new  products and services in ENSTAR's service territory. The acquisition
of  ENSTAR  increased  the  Gas  Distribution  Business'  customer  base  by
approximately 102,000 (or approximately 40%) and is expected to increase the Gas
Distribution  Business'  revenues,  expenses, operating income and net income in
2000. Based on several factors and assumptions, management currently expects the
acquisition  of  ENSTAR to be accretive to both earnings and cash flow per share
in  2000.  The factors and assumptions considered by management include, but are
not  limited  to, the price at which the Company can sell new common equity, the
timing  of  the sale of such new common equity, ENSTAR's revenue growth, and the
Company's  ability  to achieve certain synergies. For years after 2000, earnings
and  cash  flow  per  share  may or may not be accretive depending on how actual
events  compare  to  such  factors  and  assumptions.
     With the approval of profit incentive and sharing mechanisms by the MPSC in
1998,  the  Michigan operation is allowed to retain a portion of its earnings in
excess  of its authorized return, if any, and credit the remainder to customers.
Specifically,  if  the Company's return on equity for its Michigan-based natural
gas  distribution  business  exceeds  12.75%, amounts equal to 50% of the excess
return  between  12.76% and 16.75%, plus amounts equal to 75% of the excess over
16.75%,  would  be credited to customers, i.e., would be reflected prospectively
in reduced rates. In 1999, the Company was not required to credit any amounts to
its  customers.
     In  1998,  the  MPSC  also  authorized  the Company to, among other things,
suspend its GCR clause and freeze for three years in its base rates a gas charge
of $3.24 per Mcf. The GCR suspension and new rates took effect in April 1999 and
generally extend through March 2002. The $3.24 gas charge represents a reduction
of  approximately  $.33  per  Mcf  from  rates  prior  to  April  1999.  The Gas
Distribution  Business  was  able  to  offer this GCR suspension and rate freeze
partly as a result of agreements reached with TransCanada. Under 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 same three year period at a cost below
the  $3.24  charged  to  customers.  As  a  result  of  the  MPSC  order and the
TransCanada agreements, Michigan customers have lower rates and the Michigan gas
distribution  operation  retains the sales margin on the sale of gas, subject to
the  customer  profit  sharing mechanism described previously. See Note 2 of the
Notes to the Consolidated Financial Statements for additional information on the
MPSC  order  and  the  TransCanada  agreements.
     In  1999,  the  number  of customers in Michigan and at ENSTAR increased by
approximately  2.7%.  The  customer  growth  rate  for the U.S. gas distribution
industry  has  averaged  approximately  1% annually during the last three years.
     Operating  expenses  have been reduced through the early retirement program
offered during 1998, the redesign of employee benefits during 1998 and increased
use  of  technology  to  achieve  operating  efficiencies.  The Gas Distribution
Business  will  continue  its  efforts  to control or reduce operating expenses.
     The  Michigan  gas  distribution  operation  competes  with  suppliers  of
alternative  energy  sources  such  as  coal  and #6 fuel oil to meet the energy
requirements  of  its  industrial  customers.  This  competition  did not have a
material  impact  on the financial results of the Company in 1999. To lessen the
possibility  of  a  fuel  switch  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  alternate  energy  sources. At present, the residential energy
cost of natural gas in Alaska is more than 40% less than fuel oil, the next most
economical  energy  choice.
     As is the case with many gas distribution utilities, there is the potential
risk  for  industrial  and  electric  generating  plants  on  the  Company's gas
distribution  system  and  also located in close proximity to interstate natural
gas  pipelines  to  bypass  the  Company and connect directly to such pipelines.
However,  management  is  currently  unaware  of  any  significant

OPERATIONS


bypass efforts by the Company's customers. The Company has 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.
     For  information  on  environmental  matters,  regulatory  matters  and the
application  of  SFAS  71,  "Accounting  for  the  Effects  of  Certain Types of
Regulation",  refer to Notes 2 and 14 of the Notes to the Consolidated Financial
Statements.


PIPELINE  CONSTRUCTION  SERVICES

During  1999,  the  pipeline  construction  services  segment  ("Construction
Services")  made  four  business  acquisitions  that together do business in the
mid-western  and  the  southeastern  areas  of the United States. In addition to
expanding the geographic reach of Construction Services, these acquisitions have
also  expanded underground construction service offerings in new industries such
as  telecommunications  and  water  supply.  The  acquisitions also included two
non-union  businesses that can provide more competitive services to customers in
certain  regions  of  the  country.
     The businesses in the Company's construction services segment have all been
acquired  since  mid-1997  and each acquisition has been accounted for using the
purchase  method  of  accounting.  As a result, Construction Services' operating
results  for  1999,  1998  and  1997 include the results of each of the acquired
businesses  for  the  periods  subsequent  to  their  acquisition  dates.

     Construction Services also started an overhead-line construction company in
Florida  in January 1998. However, the operations of this start-up business were
halted  in  mid-1998  in  response  to  lower  than expected business levels and
earnings.  The  start-up  business  generated  an  operating loss of $.9 million
during  1998.
     Construction  Services'  primary  business  is  underground  pipeline
construction which is seasonal in nature. Construction Services generally incurs
operating  losses  during  the  winter  and  spring  months  when  underground
construction  is  inhibited  and  generates the majority of its operating income
during  the  summer  and  fall  months.

OPERATING  REVENUES - Construction  Services'  operating  revenues  increased to
$58.3  million  during  1999,  a $32.4 million (or 125%) increase over 1998. The
increase  is  due  primarily to the revenues of K&B, Iowa, Flint and Long, which
were  all  acquired  during 1999, and a $3.9 million increase in the revenues of
Sub-Surface.  Operating  revenues  during  1998  increased by $12.7 million when
compared  to  1997. The $12.7 million increase is due primarily to the timing of
the  acquisitions  of  Sub-Surface  and  King.

Page 30

OPERATING  INCOME - Construction  Services'  operating  income for 1999 was $2.6
million  compared  to  an  operating  loss  of $.1 million in 1998 and operating
income of $.8 million in 1997. Construction Services' operating income for 1998,
excluding  the  start-up  business mentioned above, would have been $.8 million.
The  increase  in  operating  income  in  1999,  when  compared  to 1998, is due
primarily  to  operating  income attributable to the businesses acquired in 1999
and  the  increase  in operating revenues of Sub-Surface, offset partially by an
increase  in  Sub-Surface's  operating  expenses.  The  1997 results reflect the
operations of Sub-Surface for the period subsequent to its acquisition in August
1997, which excludes the seasonal losses which are typical during the first half
of the year. The doubling of operating expenses in each of 1998 and 1999 was due
primarily  to  the operating expenses associated with the businesses acquired in
these periods plus an  increase in  Sub-Surface's  expenses  in  1999  as  noted
previously.

OUTLOOK - Management believes there are opportunities for growth in the pipeline
construction  industry.  Management  views  the  industry  as  large  but highly
fragmented  and  believes  that  customer  preference  is  shifting from smaller
construction  companies  to  much  larger  contractors. Management also believes
there  is  a  trend in the utility industry towards outsourcing services such as
those  provided  by  Construction Services, and management's goal is to position
Construction  Services  to  take  advantage  of  this  trend.
     Construction  Services  competes  with  small-  and  medium-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. The
Company's  goal  is  to  expand Construction Services' market share by acquiring
established  construction  companies that have a strong customer base. Achieving
these  goals  is  dependent upon the availability of good acquisition candidates
and,  among  other  things, the Company's ability to successfully integrate such
acquisitions.


ENGINEERING  SERVICES

The  Company's  engineering  services  business  ("Engineering  Services")  is
comprised  of  two  companies, Maverick Pipeline Services, Inc. ("Maverick") and
Oilfield  Materials  Consultants,  Inc. ("OMC"). The acquisition of Maverick, in
December  1997,  was  accounted  for  as a purchase. Therefore, the consolidated
financial  statements  and  the  table  below  include the results of Maverick's
operations  since  December  1997. The acquisition of OMC, in November 1998, was
accounted  for  as  a  pooling  of  interests and, accordingly, the consolidated
financial  statements  and  the  table  below  have been restated to include the
financial  results  of  OMC as if it were part of the Company for all of periods
presented.
     Maverick purchased the assets and certain liabilities of Drafting Services,
Inc.  ("DSI")  in  September  1999  and  Pinpoint Locators, Inc. ("Pinpoint") in
October  1999. DSI specializes in surveying and drafting services for interstate
pipeline  companies  while Pinpoint performs conventional and global positioning
system  (GPS) surveys of both interstate pipelines and fiber optic communication
routes.  Both  acquisitions  were  accounted  for  using  the purchase method of
accounting  and  will  be  operated  as  divisions  of  Maverick.

OPERATING  REVENUES - The  operating revenues of Engineering Services were $17.5
million  in  1999 compared to $41.3 million in 1998. The decrease in 1999 is due
primarily to lower revenues from turn-key projects and lower pipeline inspection
revenues  as  a  result  of  a  slowdown  and  deferral of pipeline projects and
engineering  work in various sectors of the energy industry. The downturn in oil
prices in late 1998 and early 1999 led to the reduction in pipeline construction
and  inspection

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


projects in 1999. There has also been a reduction or deferral of new engineering
projects  for  the  gas distribution industry due to the cash flow impact on the
industry  of  the  warm  weather  during  the  past  two  years.
     Engineering Services' operating revenues in 1998 increased $35.7 million or
nearly  eight-fold  from  1997.  Approximately  $24.5  million  of  the increase
represents  the  1998 revenues of Maverick, which was acquired in December 1997.
Maverick's  1998 revenues reflect a $20 million turn-key project it completed in
Vineland,  New  Jersey.  Maverick  performed the engineering and design work and
also managed construction of the project (this type of project is referred to as
a  "turn-key"  project).  The  remainder  of  the  increase in 1998  engineering
revenues  ($11.2  million), when compared to 1997, is attributable to OMC. OMC's
200% increase in revenues was due to growth in OMC's customer base and growth in
quality  assurance  and  quality  control  projects.

OPERATING  INCOME - Engineering  Services  incurred  an  operating  loss  of $.5
million  in 1999 compared to operating income of $2.9 million and $.8 million in
1998  and  1997,  respectively.  The significant decrease in operating income in
1999  was  due  primarily  to  decreases in operating revenues and corresponding
project  costs  as  a  result  of the slowdown and deferral of projects as noted
previously  and  unanticipated ground restoration and clean-up costs incurred in
1999  associated  with  a large pipeline turn-key project completed in 1998. The
$2.1  million  increase  in operating income in 1998, when compared to 1997, was
attributable  primarily  to the operating income of Maverick, which was acquired
in  December  1997,  and  growth  in  OMC's  business  as  noted  previously.

OUTLOOK - The  Company's goal is to expand Engineering Services in North America
and  select  foreign countries through the growth of its existing operations and
through  acquisitions.  Management  believes  there  is  a  trend in the utility
industry  towards  outsourcing  services  such  as those provided by Engineering
Services,  and  management's  goal  is  to position Engineering Services to take
advantage  of  this  trend.  It is also anticipated that the demand for turn-key
services  will  increase  and  the  Company  plans  to  aggressively pursue such
projects. In addition to providing services to the gas and petroleum industries,
Engineering  Services  also  plans  to  market  its  services  to  customers  in
telecommunications  and  other  industries.
     Engineering  Services  competes  with  regional, national and international
firms  as well as in-house engineering and field service departments. Because of
the minimal initial capital requirements, it is likely that new competition will
arise  from  other  firms  that  possess  the  professional  requirements  and
qualifications.  The  Company's  strategic  objective  is  to  build  a  sizable
underground  facilities  engineering  business  that  provides  a  wide array of
services to utilities and other companies installing underground pipe, cable and
facilities  in  North America. Achieving these goals and objectives is dependent
upon  the  availability  of good acquisition candidates and, among other things,
the  Company's  ability  to  successfully  integrate  such  acquisitions.
     There has been a reduction in oil and gas production and related activities
due  to  the  downturn in oil prices in late 1998 and early 1999. There has also
been  a  reduction  or  deferral  of  new  engineering  projects  for  the  gas
distribution industry due to the cash flow impact of the warm weather during the
past two years. As a result, Engineering Services has experienced a reduction in
the level of available projects. Management believes that the level of available
projects  will  increase  as  gas  distribution  companies  start  releasing new
engineering projects and as pipeline construction and inspection projects become
available  as  a  result  of  the  recovery  in  oil  prices  in  late  1999.


PROPANE,  PIPELINES  AND  STORAGE

The  Company  completed its first full calendar year in the propane distribution
business in 1999. The Company entered the propane distribution business with the
acquisition  of  Hotflame  Gas,  Inc. and Hotflame Transport Co., Inc. (together
known  as  "Hotflame")  on  March  31,  1998.  The  acquisition  of Hotflame was
accounted for as a purchase and, therefore, only the results of operations since
April  1998  are included in the consolidated financial statements and the table
below.  Hotflame's  1998  operating  results  do  not include the winter heating
months  of  January  through  March.
     The  Company's pipeline and storage operations consist of several pipelines
and an ownership interest in a gas storage facility, all of which are located in
Michigan.

</TABLE>


OPERATING  REVENUES - Operating  revenues  were $6.3 million in 1999 compared to
$4.9  million  in  1998 and $3.0 million in 1997. The increases in 1999 and 1998
were  due  primarily to the operating revenue of Hotflame, which was acquired on
March  31,  1998.

OPERATING  INCOME - The  Company's  Propane,  Pipelines  and Storage segment had
operating  income  of $2.3 million in 1999 compared to $1.6 million in 1998. The
increase  was due primarily to pipeline expense reductions and the operations of
Hotflame.  As  discussed  above,  the  operating  results  for  1998 include the
operating  income  of  Hotflame  earned after its acquisition on March 31, 1998.
     Weather  in  Hotflame's  market  area  was  10%  warmer than normal in 1999
compared  to  22%  warmer  than  normal  in  1998.  Operating  income  on  a
weather-normalized basis would have been higher by $.3 million for both 1999 and
the  period  of  April  through  December  of 1998. The impact of weather on the
operating  income of the propane, pipelines and storage segment relates entirely
to  the  propane business. In addition to the impact of weather, Hotflame's 1999
profit  margins  were  slightly  lower as a result of price reductions caused by
increased  competition  in  the  propane  industry.
     Operating  income  in  1998, when compared to 1997, was generally unchanged
with  nearly  all  income  coming  from the pipeline and storage operations. The
propane  operation  did  not  contribute any operating income in 1998 due to the
combination  of the warm weather and the fact that the operating results did not
include  operating  income  from the profitable winter heating months of January
through  March.

OUTLOOK - Management believes that the gas pipeline and storage operations could
experience  opportunities  for  growth  with  the  increased deregulation of gas
markets.  As  gas  markets  expand or are deregulated, management feels that the
quantity  of  gas  moving  through the Great Lakes Region will increase, thereby
creating  additional  pipeline  and  storage  opportunities.
     The  Company's  propane  business  competes  with  other  regional  propane
providers  and  with  other  energy  sources  such  as natural gas, fuel oil and
electricity.  The  propane business has become increasingly competitive and less
profitable,  which  necessitates  large scale operations to be successful in the
long term. The Company will continue to assess regional growth opportunities and
the  strategic  fit  of  this  business  over  the  coming  year.


ENERGY  MARKETING

The  Company  sold the subsidiary comprising its gas marketing business ("Energy
Services")  effective  March  31,  1999.
The  business  was  sold  because  management  concluded that it did not fit the
Company's  new  strategic  direction  due  to  the high risks and generally poor
returns associated with the business. The Company recognized a gain on the sale.
The  gain
is  reported  in other income (discussed in the subsequent section) and thus, is
not  reflected  in  operating  income  in  the  following  table.

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


GAS  MARKETING  MARGIN - Gas  marketing  margin for 1999, when compared to 1998,
decreased  by  $2.9  million. There were no gas marketing revenues subsequent to
March  31, 1999, the effective date of the sale of Energy Services, which is the
primary  reason  for  the  decrease  in  margin.
     Gas  marketing  margin  for 1998 decreased by $4.7 million when compared to
1997  due  primarily  to  the impact of warm weather on market demand, increased
competition,  restructuring  activities at Energy Services and a decrease in gas
marketing volumes. The warm weather reduced prices which decreased gas marketing
margins.  During  1998,  Energy  Services  terminated agreements with all of its
third-party  gas  marketing  companies  in  an effort to reduce risks, eliminate
lower  margin  transactions  and  improve  profitability.

OPERATING  INCOME - Energy Services had an operating loss of $.3 million in 1999
compared to an operating loss of $.7 million in 1998 and operating income of $.2
million  in  1997.  The  smaller operating loss in 1999 was due primarily to the
results  of  restructuring  activities undertaken in 1998 (discussed previously)
and  the  timing  of  the  sale  of  Energy  Services.  Energy Services was sold
effective  March  31,  1999 and therefore the 1999 operating loss of $.3 million
includes  results  from  January  through  March  only.
     The  decrease  in  operating  income  in 1998, compared to 1997, was due to
additional  overhead and administrative expenses incurred to properly manage the
gas  marketing  business  and  the  decrease  in  gas marketing margin discussed
previously, offset partially by a corresponding decrease in third-party marketer
incentive  payments.

</TABLE>

DIVESTITURE  OF  ENERGY  MARKETING  BUSINESS - The  Company  sold the subsidiary
comprising  its  energy  marketing  business  effective  March  31,  1999.  The
divestiture  resulted  in  a  gain  of  $1.1  million  ($.7  million after tax).

DIVESTITURE  OF  NOARK  INVESTMENT - On  January  14, 1998, the Company sold its
entire  interest  in  the  NOARK Pipeline System Partnership ("NOARK"). Refer to
Note  15  of  the  Notes to the Consolidated Financial Statements for additional
information  regarding  NOARK.
     In December 1997, the Company reduced its reserve for NOARK by $5.0 million
(after-tax) based on the terms of the pending sale. The sale occurred in January
1998 and, including subsequent adjustments, resulted in a final gain on the sale
of  NOARK  of  $1.7  million  (after-tax).  The adjustments to the gain included
income  tax  benefits  related  to  tax  losses generated by the partnership and
adjustments  to  discount rates used to compute the present value of future cash
flows  pursuant  to  the  terms of the sale. The discount rates were adjusted to
better  reflect  actual  market  rates  at  the  time  of  the  sale.

INTEREST  EXPENSE - Interest expense increased by $5.8 million (or 39%) in 1999,
when  compared to 1998, due to an increase in the level of debt outstanding from
1998  to  1999.  The Company incurred the additional debt to finance its ongoing
capital  expenditure and business acquisition programs and for general corporate
purposes.  The  Company  incurred  $290 million of additional short-term debt on
November  1,  1999  to  finance  the  acquisition  of ENSTAR. Approximately $3.3
million of the increase in interest expense in 1999 relates to this $290 million
of  debt.
     Interest  expense  increased  by  $1.8 million (or 13%) in 1998 compared to
1997 due to the higher levels of debt outstanding during the first half of 1998.
The  additional  debt had been incurred to finance the Company's ongoing capital
expenditure  and  business  acquisition  programs  and  for  general  corporate
purposes.  During August 1998 the Company sold 1.82 million shares of its common
stock  and  used  a  significant portion of the net proceeds to repay short-term
debt.

     See  Note  5 of the Notes to the Consolidated Financial Statements for more
information  on  debt  issuances  and  refinancings.

OTHER - In  1999,  other income increased by $1.7 million when compared to 1998.
Approximately  $.8  million  of  the increase relates to life insurance proceeds
received  upon  the death of a retired Company executive, $.4 million relates to
gains  on the sale of pipeline property and other equipment, $.2 million relates
to  an  increase in equity income from partnership investments and the remainder
is  attributable  to  higher  miscellaneous  non-operating  income.
     Other  income  increased  by $.6 million in 1998 when compared to 1997. The
increase  was  due  primarily  to  the  impact  of  discontinuing  the Company's
unprofitable  appliance merchandising programs in 1997 and an increase in equity
income  from partnership investments in gas pipeline and gas storage facilities.


ACCOUNTING  METHOD  CHANGE  AND  EXTRAORDINARY  ITEM

The Company changed its method of accounting for property taxes during 1998. The
cumulative  effect of the change in accounting method increased 1998 earnings by
$1.8  million.  The Company also incurred an extraordinary charge of $.5 million
after-tax  during 1998 for the early redemption of all of its outstanding 8.625%
debentures  due April 15, 2017. Refer to Note 1 of the Notes to the Consolidated
Financial  Statements  for  more  information  on  these  items.


LIQUIDITY  AND  CAPITAL  RESOURCES

issuance,  of Company stock issued for acquisitions. Also, 1998 includes $14,073
of  Company  stock issued for the acquisition of OMC. The acquisition of OMC was
accounted  for  as  a  pooling  of  interests.
</TABLE>


     Property  additions  for  the Gas Distribution Business represent primarily
new  customer  service  lines and, to a lesser extent, gas main and service line
replacements. In addition, the Company invested approximately $2.4 million, $4.5
million  and $8 million in technology in 1999, 1998 and 1997, respectively. This
technology  consists  of  automated  meter  reading,  automated  dispatch  and
scheduling,  in-truck  computer  terminals  and  other  computer  infrastructure
improvements  which  have increased customer service and operational efficiency.
     Business  acquisitions were approximately $305.1 million, $20.4 million and
$15.6  million in 1999, 1998 and 1997, respectively. The significant increase in
1999  was  due  to  the  acquisition  of  ENSTAR for approximately $290 million.
     In  2000,  the Company plans to spend approximately $50 million on property
additions  for the Gas Distribution and Diversified Businesses. In addition, the
Company  plans to incur additional expenditures for business acquisitions during
2000.

CASH  FLOWS  FROM  OPERATIONS - The  Company's  net cash provided from operating
activities totaled $41.2 million in 1999, $24.7 million in 1998 and $9.0 million
in  1997.  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 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  with  available  capacity

approximating  35%  to 40% of average annual gas sales. Generally, gas is stored
during  the months of April through October and withdrawn for sale from November
through  March.

CASH  FLOWS  FROM  FINANCING - The  Company  received  net  cash  from financing
activities  of  $287.4 million, $4.9 million and $32.4 million in 1999, 1998 and
1997,  respectively.

     The Company issued 374,000 shares, 367,000 shares and 298,000 shares of its
common  stock  in  1999,  1998  and  1997,  respectively,  to  meet the dividend
reinvestment  and  stock  purchase  requirements  of  the Company's Direct Stock
Purchase  and  Dividend  Reinvestment  Plan ("DRIP"). Since May 1999 the Company
purchased  159,000  shares  of  its common stock on the open market. The Company
also  purchased  162,000  shares of its common stock on the open market in 1997.
     In August 1998, the Company sold 1.82 million shares of its common stock in
a  public  offering.  The  proceeds  of  the  offering  were $26.2 million after
underwriting  discounts  but  before expenses. The Company used the net proceeds
from  the  stock  issuance  to  repay  short-term debt and for general corporate
purposes.
     In  November 1999, the Company called for redemption all outstanding shares
of its $2.3125, Series A Convertible Cumulative Preferred Stock and Series A, B,
C, and D Cumulative Preferred Stock of its subsidiary, SEMCO Energy Gas Company.
Holders  of  the  6,168  outstanding  shares  of  $2.3125,  Series A Convertible
Cumulative  Preferred  Stock  had  the  option of receiving $25 in cash for each
share redeemed or converting each share into 4.11 shares of the Company's common
stock.  1,055  shares  were redeemed for cash and 5,113 shares were converted to
common  stock.  The Company paid cash of $105 per share to holders of the 31,000
outstanding  shares of Series A, B, C, and D Cumulative Preferred Stock. A small
premium  was  paid  as  part  of  the  redemption  of  the Series A, B, C, and D
Cumulative  Preferred  Stock and is reflected in dividends on preferred stock in
the  Consolidated  Statement  of  Income  for  1999.
     In April 1998 the Company redeemed all of its outstanding 8.625% debentures
due  April  15, 2017. The redemption was accomplished using short-term debt. The
Company  issued,  in  November  1998,  $5 million of 6.40% medium-term notes due
November 2008, $15 million of 6.50% medium-term notes due November 2005, and $10
million  of  7.03%  medium-term  notes  due  November 2013. In October 1997, the
Company  issued  $30  million of 6.83% notes due October 2002 and $30 million of
7.20%  notes  due  October 2007. The net proceeds from the issuance of the notes
were  used  to  repay  short-term  debt  and  for  general  corporate  purposes.
     The  Company's  net  funds  borrowed  (paid)  on  notes payable were $302.3
million,  ($20.6  million)  and  ($20.0  million)  in  1999,  1998  and  1997,
respectively.  On  November  1,  1999,  the  Company financed the acquisition of
ENSTAR  with  a  $290  million  unsecured  bridge  loan facility ("ENSTAR bridge
loan").  The  Company made payments of $3.1 million and $9.2 million during 1999
and  1998,  respectively,  on  a  note payable associated with the sale of NOARK
("NOARK  note")  (See  Note  15  of  the  Notes  to  the  Consolidated Financial
Statements). The net change in notes payable includes the combined cash borrowed
or  paid  on  the  Company's  short-term  lines of credit with banks, the ENSTAR
bridge  loan  and  the  NOARK  note.
     Cash dividends paid per share for common shareholders were $.863, $.744 and
$.70 in 1999, 1998 and 1997, respectively. The 1999 dividends include a one-time
special  cash  dividend  of  $.05  per  share.

NON-CASH  FINANCING  ACTIVITIES - The  Company  issued  .2  million  shares, 1.3
million  shares  and  less  than  .1  million  shares of its common stock to the
shareholders of businesses acquired during 1999, 1998 and 1997, respectively. Of
the  shares issued in 1998, .9 million were for the acquisition of OMC which was
accounted for using the pooling of interests method of accounting. See Note 3 of
the  Notes  to the Consolidated Financial Statements for more information on the
OMC acquisition. As part of a business acquisition in 1999, the Company owes $.8
million  to  the  shareholder  of  the  business  acquired. The $.8 million plus
interest  must  be  paid  on  or  before  April  2002.

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  December  31, 1999, the Company had $110 million of short-term
credit  facilities,  of  which  $25.4  million  was  unused.
     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  or  trust  preferred  securities. The bridge loan matures on October 30,
2000.  Prepayments  of  $56,000,000  will  be required on the six and nine month
anniversaries  of  the funding date (November 1, 1999) if the bridge loan is not
prepaid  prior  to  such  dates.
     In  November  1999,  the  Company  and SEMCO Capital Trust I, SEMCO Capital
Trust  II  and  SEMCO  Capital Trust III ("Capital Trusts") filed a registration
statement  on  Form  S-3 ("1999 registration statement") with the Securities and
Exchange  Commission  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. The $500 million registered in the 1999
registration  statement includes an aggregate principal amount of $142.4 million
of  unsold  securities  registered  by  the  Company on a registration statement
declared  effective  in
July  1998.
     During  2000, the Company will make the final payment of $.8 million on the
NOARK  note.  See  Note 15 of the Notes to the Consolidated Financial Statements
for  a  discussion  of  the  amounts  to be paid in conjunction with the sale of
NOARK.
     The  Company's  ratio  of earnings to fixed charges was 2.18, 2.17 and 2.42
for  1999,  1998  and  1997,  respectively.


MARKET  RISK  INFORMATION

The  Company's  primary market risk arises from fluctuations in commodity prices
and  interest  rates.  The Company manages interest rate risk through the use of
derivative  instruments  and  limits  the  use  of  such  instruments to hedging
activities.  If  the Company did not use derivative instruments, its exposure to
such risk would be higher. See Note 8 of the Notes to the Consolidated Financial
Statements  for  additional  information  on  the  Company's  risk  management
activities.
     The  Company  is  subject  to  interest  rate  risk  in connection with the
issuance  of  variable-  and fixed-rate debt. In order to manage interest costs,
the  Company  uses  interest  rate  swap  agreements  and  exchanges  fixed- and
variable-rate  interest  payment  obligations  over  the  life of the agreements
without  exchange  of  the  underlying principal amounts. A sensitivity analysis
model  was  used  to  calculate  the  fair values of the Company's interest rate
swaps,  utilizing  applicable  forward  interest rates in effect at December 31,
1999.  The  sensitivity  analysis  involved increasing or decreasing the forward
rates  by a hypothetical 10% and calculating the resulting unfavorable change in
the  fair values of the interest rate sensitive instruments. The results of this
analysis, which may differ from actual results, showed this type of change would
reduce  the  fair  values by approximately $2.4 million. Losses in excess of the
amounts  determined  in  the sensitivity analysis could occur if market rates or
prices  exceed  the  10% shift used for the analysis. The analysis also does not
quantify  short-term  exposure  to  hypothetically adverse price fluctuations in
inventories.  See  Note  8 of the Notes to the Consolidated Financial Statements
for  additional  information on the Company's accounting policies for derivative
instruments.
     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  derivative  instruments  to  manage  its  exposure to
commodity  price risk since all of the natural gas requirements of the Company's
Michigan  gas  distribution  operations are covered under the TransCanada supply
arrangement

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


and  ENSTAR's  natural  gas  requirements are primarily covered by two long-term
supply arrangements and an RCA-approved commodity cost pass through mechanism to
its  customers.
     Prior to the sale of Energy Services on March 31, 1999, the Company entered
into various long-term sales commitments which extended up to 60 months into the
future.  The  Company  also  utilized  derivative  financial  and  commodity
instruments,  including  futures  contracts, options and swaps, to reduce market
risk  associated with fluctuations in the price of gas. Since the sale of Energy
Services,  the  Company  no  longer  uses  these  types  of  instruments.


IMPACT  OF  INFLATION

The  cost  of  gas  sold  by  ENSTAR  is recovered from natural gas distribution
customers  on  a  current  basis  through  its  purchased gas adjustment ("PGA")
clause.  Prior  to  April  1,  1999,  the  cost  of gas sold by the Michigan gas
distribution operations was recovered from natural gas distribution customers on
a  current  basis  through  its  GCR  clause. The MPSC authorized the Company to
suspend its GCR clause and freeze for three years in its base rates a gas charge
of  $3.24  per Mcf. The GCR suspension and rate freeze took effect in April 1999
and  generally  extend  through  March  2002.  See  Note  2  of the Notes to the
Consolidated  Financial  Statements  for more information regarding the Michigan
rate  freeze.
     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.


YEAR  2000

STATE  OF READINESS - The Company uses computer systems, equipment, software and
related  devices  ("technology  systems")  that  have  date-sensitive  embedded
technology  that  previously could not distinguish between the year 1900 and the
year  2000  ("Y2K").  If  not  corrected, this could have caused the Company to,
among  other things, report inaccurate data, issue inaccurate bills or incur gas
delivery  problems. The Company initiated an enterprise-wide plan to prepare for
Y2K  (the  "Y2K  Plan").  The Y2K Plan had four phases: (i) identification; (ii)
remediation;  (iii)  testing;  and (iv) contingency planning. The identification
phase  included  identification,  inventory, assessment, and prioritization plan
development  for  all  technology  systems.  The  remediation phase involved the
upgrading, modification, or replacement of technology systems. The testing phase
included  testing  the  remediated  technology  systems  to  ensure  that  they
accurately  handle  the  year 2000 date and monitoring the remediated systems to
ensure  that  Y2K problems were not reintroduced. The contingency planning phase
involved the development of contingency plans to address certain risk scenarios.
     The  Y2K  Plan was used for traditional information technology ("IT") which
includes  essential  business  systems  such  as  payroll,  billing,  accounting
systems,  wide  area networks, local area networks, personal computers, etc. The
Company  also  used  the  Y2K  Plan  for  process control computers and embedded
systems  contained  in  buildings,  equipment  and  the  gas supply and delivery
systems.
     The  Company  completed  all  four  phases of its Y2K Plan during 1999. The
Company  has  been  operating  in  2000  and  has experienced no significant Y2K
related  problems  with  its  internal  systems  or  with  any critical vendors,
suppliers  or  customers.  However,  the  Company  continues to monitor internal
systems  as  well  as vital functions of the Company dependent on third parties.
Contingency  plans  are still in place if any Y2K issues surface in the upcoming
months. Of course, there can be no assurance as to whether the contingency plans
will successfully address all contingencies that may arise in the future. In the
event  that  the  Company  is  unsuccessful in addressing any future Y2K issues,
there  could  be a material adverse effect on the Company's liquidity, financial
condition  and  results  of  operations.

COST  OF  REMEDIATION - The  Company  expensed  the  cost  of  modifications  to
technology  systems  as  incurred, while capitalizing and amortizing the cost of
new  software  over its useful life. Expenses incurred through December 31, 1999
related  to  the  Y2K  Plan  were  approximately  $2.3  million. The Company has
incurred  an  opportunity  cost  for  implementing  the  Y2K  Plan  by deferring
potentially  beneficial  IT  projects.

RISK  ASSESSMENT - The  Company  identified  what  it  believed  were  the  most
significant worst case Y2K scenarios. These scenarios were (i) interference with
the  Company's  ability  to  receive  and  deliver  gas to customers and perform
services  for customers; (ii) interference with the Company's ability to monitor
gas  pressure and safety throughout the Company's gas distribution system; (iii)
interference  with  communications  during  safety  related emergencies and (iv)
interference  with  the  Company's  ability  to  bill  and receive payments from
customers.  These scenarios could have resulted in the Company not being able to
deliver gas or perform other services for a period of time, which could have had
a  material  adverse  effect on the Company's liquidity, financial condition and
results  of  operations.  The Company's Y2K Plan was used to address these worst
case  scenarios  and,  as  a  result,  none  of the scenarios have materialized.


NEW  ACCOUNTING  STANDARDS

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
balance  sheet  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.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


1.     SIGNIFICANT  ACCOUNTING  POLICIES

COMPANY  DESCRIPTION - SEMCO Energy, Inc., is an investor-owned holding company.
SEMCO  Energy,  Inc.  and its subsidiaries (the "Company") operate four business
segments:  (1)  gas  distribution;  (2)  pipeline  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 business 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 Alaska-based
operation  and  the  Michigan-based  operation  are  known  together as the "Gas
Distribution  Business"  and  operate  as  divisions of SEMCO Energy, Inc. SEMCO
Energy Gas Company, which had conducted the Michigan gas distribution operation,
was  merged  into  SEMCO  Energy,  Inc.  on  December  31,  1999.  The  pipeline
construction  services segment ("Construction Services") currently does business
in  the  mid-western and southeastern areas of the United States. In addition to
constructing  underground  gas pipelines, Construction Services is expanding its
underground  construction  services  into  other  industries  such  as
telecommunications  and  water  supply.  The  engineering  services  segment
("Engineering  Services")  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  ("Energy  Services")
effective  March  31,  1999.

BASIS OF PRESENTATION - The financial statements of the Company were prepared in
conformity with generally accepted accounting principles. 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.
Certain  reclassifications  have  been  made  to  the  prior  years'  financial
statements  to  conform  to  the  1999  presentation.

PRINCIPLES  OF CONSOLIDATION - The consolidated financial statements include the
accounts of SEMCO Energy, Inc. and its wholly-owned subsidiaries. Investments in
unconsolidated companies at least 20% owned, but not greater than 50% owned, are
reported  using  the  equity  method  of  accounting.
     Certain  of  the  Company's  diversified businesses, primarily Construction
Services  and Engineering Services, supply services at a profit to the Company's
regulated  gas  distribution business. In these situations, 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, $400,690, $595,000 and
$437,000  of  profit on revenues earned from the Company's regulated business by
the  Company's diversified businesses was not eliminated during consolidation in
1999,  1998  and  1997,  respectively.  All  other  significant  intercompany
transactions  have  been  eliminated.

RATE REGULATION - The rates of 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  ("MPSC")  authorizes  the  rates  charged  to  all  of the remaining
Michigan  customers.  The  gas  distribution  operation  in Alaska is subject to
regulation by the Regulatory Commission of Alaska ("RCA") which has jurisdiction
over,  among  other  things,  rates,  accounting  procedures,  and  standards of
service.

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  4.0%,  3.9%  and  3.6%  for  the  years  1999,  1998  and  1997,
respectively. Certain investments in unconsolidated companies recorded using the
equity  method  are  reported in the property of the diversified businesses. See
Note  13  for  further  discussion.

GAS IN UNDERGROUND STORAGE - The gas inventory held by the Battle Creek division
of  the Gas Distribution Business is stated at last-in, first-out ("LIFO") cost.
At  December  31,  1999  and  1998,  the  replacement  cost  of the Battle Creek
division's  gas

Page 45

<PAGE>
SEMCO  Energy,  Inc.  and  Subsidiaries

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


inventory  did  not  exceed  the  LIFO  cost.  The remainder of gas inventory in
Michigan  is  reported  at  average  cost.
     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.
Goodwill  is  amortized on a straight-line basis over periods of up to 40 years.
Periodically,  the  Company  reviews  the  recoverability  of  goodwill.  The
measurement  of possible impairment is based primarily on the ability to recover
the  balance  of  the  goodwill  from expected future operating cash flows on an
undiscounted  basis.  In management's opinion, no impairment existed at December
31,  1999.  Amortization  expense  was $1,593,121 in 1999, $515,444 in 1998, and
$339,347  in  1997.  Amortization  expense  in  1999  included  two  months  of
amortization  attributable  to  the  acquisition  of  the  Alaska-based  gas
distribution  operation.  See  Note  3  for  further  discussion.

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. Engineering
Services  and  Construction Services recognize revenues as services are rendered
and recognize accrued revenue for services rendered but not billed at month end.
The  propane  business  recognizes  propane  sales  in  the same period that the
propane is delivered to customers. Prior to its sale, Energy Services recognized
marketing  revenues, and any related hedging gains or losses, in the same period
natural  gas was delivered to customers. See Note 8 for further discussion about
Energy  Services'  hedging  activities.

COST  OF  GAS - Prior  to  April  1,  1999,  the  Company's  Michigan-based  gas
distribution  operation  had  a  regulator  approved  gas  cost recovery ("GCR")
mechanism for the geographic areas subject to the regulatory jurisdiction of the
MPSC,  and a purchased gas adjustment ("PGA") mechanism for the geographic areas
subject  to  the  jurisdiction  of  the  City  Commission of Battle Creek, which
allowed  for  the  adjustment  of  rates  charged  to  customers  in response to
increases  and  decreases in the cost of gas purchased. Effective April 1, 1999,
the  MPSC  authorized the Company to suspend its GCR clause and freeze for three
years  in  its  base rates a gas charge of $3.24 per Mcf. The GCR freeze and new
rates  generally  extend  through March 2002. As a result of the GCR suspension,
customer  rates  in  Michigan will not be adjusted during the three year period.
See  Note  2  for  more  information.
     The  Alaska-based  gas distribution operation also has a regulator approved
PGA  mechanism which allows for the adjustment of rates charged to customers for
increases  and  decreases  in the cost of gas purchased. All gas sales rates are
adjusted  annually  to  reflect changes in the operation's cost of purchased gas
based  on  estimated  costs  for  the  upcoming
12-month  period.  The  PGA  may  be adjusted quarterly if it is determined that
there  are  significant  variances  from  the  estimates  used  in  the  annual
determination. Any difference between actual cost of gas purchased and the RCA's
approved  rate  adjustment  is  deferred  and  included with applicable carrying
charges  in  the  next  PGA.
     In  accordance  with the GCR and PGA mechanisms, the Company had $3,009,000
recorded in current assets at December 31, 1999 for gas charges recoverable from
customers.  Also  at  December  31, 1999, the Company had $5,715,000 recorded in
current  liabilities  for  amounts payable to customers in accordance with these
mechanisms.

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.

EXTRAORDINARY  CHARGE - During 1998, the Company redeemed all of its outstanding
8.625%  debentures  due  April  15,  2017  at  a redemption price of 104% of the
principle  amount  of  $23,548,000.  The  payment  of  the  call premium and the
unamortized  debt  expense  associated  with  the  diversified businesses of the
Company  is  reflected  in  the  consolidated statement of income for 1998 as an
extraordinary  charge  of  $499,000  after-tax.

CHANGE  IN  METHOD OF ACCOUNTING - During 1998, the Company implemented a change
in  its  method of accounting for property taxes so that such taxes are expensed
monthly during the fiscal period of the taxing authority for which the taxes are
levied. This change provides a better matching of property tax expense with both
the  payment  of  services  and those services provided by the taxing authority.
Prior  to  1998,  the  Company  expensed  property taxes monthly during the year
following  the  assessment  date.  The  cumulative  effect  of  this  change  in
accounting  for  property taxes increased 1998 earnings by $1,784,000 after-tax.
The  pro  forma  effect on prior years' consolidated net income of retroactively
recording  property  taxes as if the new method of accounting had been in effect
for  all  periods  presented  is  not  material.

2.     REGULATORY  MATTERS

1999  RCA  ORDER - In  July  1999,  the  Company  announced that it had signed a
definitive  purchase  and  sale  agreement  to  acquire  the  assets and certain
liabilities  of  ENSTAR  Natural Gas Company and the outstanding stock of Alaska
Pipeline  Company  (together  known  as "ENSTAR") from Ocean Energy, Inc ("Ocean
Energy").  In October 1999, the Company received an order from the RCA approving
a  joint  application  for the transfer of the Certificate of Public Convenience
and  Necessity  held  by  ENSTAR  Natural  Gas  Company  and  for  a transfer of
controlling  interest  in  Alaska  Pipeline  Company.  The RCA's order contained
certain  conditions,  including  the  obligation to file by July 1, 2000 certain
revenue  requirement  and  cost  of service information and the prohibition from
encumbering  ENSTAR's  assets  for financing of non-utility business activities.

1998  MPSC  ORDER - In  September  1998,  the  division  of the Gas Distribution
Business  subject  to  the  jurisdiction of the MPSC received authority from the
MPSC  to: (1) implement an experimental residential gas customer choice program;
(2)  suspend  its  GCR clause; (3) roll into its base rates and freeze for three
years  a  gas  charge  of  $3.24  per  thousand  cubic  feet ("Mcf"); (4) freeze
distribution  rate  adjustments for the same three year period, with exceptions;
(5) suspend the income sharing mechanism adopted in October 1997 and adopt a new
income  sharing mechanism for use during the 1999, 2000 and 2001 calendar years;
and (6) establish gas service performance criteria. The new rates took effect in
April  1999  and  generally  extend  through  March  2002.
     Under  the  experimental  residential  gas  customer-choice  program  and a
similar program in Battle Creek, up to approximately 8,300 residential customers
per  year will be allowed to choose their own gas supplier during the three year
period  that  began  April  1,  1999.  As  a  result,  up  to 25,000 residential
customers,  10%  of  the  Michigan residential customer base, will be allowed to
choose  their  own  gas  supplier  by  the  third  year  of  the  programs.  The
customer-choice  gas  is  delivered

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


under  a  tariff  similar  to an existing tariff used to provide such service to
Commercial  and  industrial  customers. The program has not, and is not expected
to, significantly affect the income of the Gas Distribution Business because the
approved  rates  for  transportation  service  are designed to recover all costs
other  than  the  cost  of  gas  and  provide a return in approximately the same
amounts  as  from  Michigan  residential  customers  for whom the Company is the
natural  gas  supplier.
     Several  of  the  changes in the MPSC order are interrelated. The $3.24 gas
charge represents a reduction of approximately $.33 per Mcf from the rates prior
to  April  1999.  The suspension of the GCR clause means that customers will pay
$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 Gas Services,
Inc.  ("TransCanada").  Under 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 at a cost below the $3.24 price
charged  to  customers.  As  a  result,  the Michigan gas distribution operation
retains  the  sales  margin  on  the  sale  of gas, subject to a customer profit
sharing  mechanism described below. Included in receivables at December 31, 1999
is  approximately  $38  million  representing amounts ultimately due the Company
under the terms of the TransCanada agreements. Under the agreements, the Company
does  not  have  title to gas in its leased storage facilities and it must remit
payments  to TransCanada in accordance with a contractual delivery schedule that
is  designed  to  include  the  gas  delivered to the leased storage facilities.
Differences  between  these  scheduled  deliveries  and actual deliveries to the
Company's  distribution  system or Company-owned storage facilities result in an
amount  due  the  Company.  This  amount  is settled between TransCanada and the
Company  after  each  anniversary  date  (April  1)  of  the  agreements.
     The  MPSC  order  is applicable only in the geographic areas subject to the
regulatory  jurisdiction  of  the  MPSC,  and,  therefore, does not govern rates
regulated  by  the City of Battle Creek, Michigan. However, the Gas Distribution
Business  voluntarily  reduced its Battle Creek gas charge to the $3.24 level to
correspond  with  its  gas  charge  under  the  MPSC  order.
     There are two exceptions to the three year distribution rate freeze: first,
the profit incentive and sharing mechanism described in the following paragraph,
and  second,  rate revisions arising in response to unanticipated legislative or
accounting  actions.
     The  new  profit  incentive  and  sharing  mechanism  substantially matches
mechanisms  approved  by  the  MPSC for two other major natural gas utilities in
Michigan  and  provides  for  a  higher threshold than was previously applicable
(i.e.  12.75% return on equity). Under the mechanism, if the Company's return on
equity  for its Michigan-based natural gas distribution business exceeds 12.75%,
amounts  equal  to  50%  of  the  excess  return between 12.76% and 16.75%, plus
amounts  equal  to 75% of the excess over 16.75% would be credited to customers,
i.e.,  would  be  reflected  prospectively  in  reduced  rates.  Four safety and
reliability  performance  measures  need  to  be  met in order not to reduce the
return  on  equity  threshold  used  in  the  income  sharing  mechanism.

1997  GENERAL  RATE  CASE - In October 1997, the MPSC approved the merger of the
Company's  two  MPCS  regulated  gas  distribution  subsidiaries,  Southeastern
Michigan  Gas  Company  and  Michigan  Gas  Company, in a general rate case. The
approval  of  the merger allowed the Company to combine the rate structures, GCR
clauses,  tariffs,  and  rules  and  regulations  for  those  two  companies. It
additionally  granted  a rate increase to the combined companies, which included
the  recovery  of  costs  related  to a change in accounting for retiree medical
benefits. There were also adjustments to other fees and rates as a result of the
rate case. Overall, the adjustments offset one another and the rate case did not
have  a  material  impact  on the Company's results of operations. The MPSC also
granted the Company the ability to offer its commercial and industrial customers
the  option to aggregate their demand for gas into a pool and choose a supplier.
Finally,  the  MPSC approved an incentive regulation, where profits generated in
excess  of  the authorized rate of return would be shared with the customers. As
discussed  previously, a 1998 MPSC order suspended this incentive regulation and
adopted  a  new  profit incentive and sharing mechanism for use during the 1999,
2000  and  2001  calendar  years.

REGULATORY  ASSETS AND LIABILITIES - The Gas Distribution Business is subject to
the  provisions  of  Statements  of  Financial Accounting Standards ("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.  The  following  regulatory assets and liabilities were
recorded  in the consolidated statements of financial position as of December 31
(in  thousands  of  dollars):

     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.


3.     MERGERS  AND  ACQUISITIONS

ENSTAR  ACQUISITION AND 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. The Company acquired ENSTAR
from  Ocean  Energy  for  approximately  $290,000,000  in  cash,  which included
adjustments for working capital and the purchase of $58,700,000 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 amount of purchase price in excess of these estimated fair
values  classified  as goodwill. The goodwill was approximately $134,400,000 and
is  being  amortized  on  a  straight-line  basis over 40 years. The preliminary
allocation  of  the purchase price is subject to adjustment based on the results
of  an  independent  study  being  conducted  to  determine  actual fair values.
However,  the Company believes that the preliminary determination of fair values
reasonably  present  the  significant  effects  of  the  acquisition  of ENSTAR.
     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 $170,000,000 of
medium-term  notes,  $35,000,000  of  trust  preferred  securities and 7,084,000
shares  of  common  stock of the Company producing net proceeds of approximately
$85,000,000  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 $290,000,000 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.

     The  acquisition  of  OMC  was accounted for under the pooling of interests
accounting  method,  and  accordingly, the consolidated financial statements for
the  periods  prior to the merger were restated to include the financial results
of  OMC. For the periods preceding the merger of the Company and OMC, there were
no  intercompany  transactions  which  required  elimination  from  the combined
results  of  operations  and  there were no adjustments necessary to conform the
accounting  practices  of  the  two  companies.
     The  remainder of the diversified business acquisitions have been accounted
for  using  the  purchase  method  of  accounting.  As  a  result, the Company's
operating  results  for  1999,  1998,  and  1997  include  the  results of these
businesses  for  the  period subsequent to their acquisition dates. Any goodwill
associated  with these acquisitions is being amortized on a straight line method
over  a  period  of  up  to 40 years. There were no adjustments necessary to the
accounting  practices  of  these  companies to conform with the practices of the
Company.

     In  addition  to  the  consideration  shown  above,  the  acquisition  of
Sub-Surface  included  non-compete agreements requiring payments of $235,000 per
year during the two years following the acquisition and $160,000 per year during
the third through fifth year following the acquisition. The Hotflame acquisition
also included non-compete agreements requiring payments of approximately $67,000
per  year  during  the  three years following the acquistion. In addition to the
consideration  shown  above,  the  acquisitions  of K&B and Pinpoint provide for
additional  amounts to be paid if certain post-acquisition operating results are
achieved.  See  Note  14  for  further  information.


4.     INCOME  TAXES

SFAS  NO.  109 - The  Company  accounts for income taxes in accordance with SFAS
109,  "Accounting  For Income Taxes." SFAS 109 requires an annual measurement of
deferred tax assets and deferred tax liabilities based upon the estimated future
tax  effects  of  temporary  differences  and  carry  forwards.

PROVISION  FOR  INCOME  TAXES - The components of the provision for income taxes
are  as  follows  (in  thousands  of  dollars):

5.     CAPITALIZATION

REGISTRATION  STATEMENT - In  November 1999, the Company and SEMCO Capital Trust
I, SEMCO Capital Trust II and SEMCO Capital Trust III ("Capital Trusts") filed a
registration  statement  on  Form  S-3  ("1999 registration statement") with the
Securities  and  Exchange  Commission  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 $500,000,000. The $500,000,000 registered in
the  1999  registration  statement  includes  an  aggregate  principal amount of
$142,400,000  of  unsold  securities registered by the Company on a registration
statement  declared  effective  in  July  1998.

COMMON  STOCK  EQUITY - The  Company  issued  374,000 shares, 367,000 shares and
298,000  shares of it common stock in 1999, 1998 and 1997, respectively, to meet
the  dividend  reinvestment  and  stock  purchase  requirements of the Company's
Direct  Stock  Purchase  and Dividend Reinvestment Plan ("DRIP"). Since May 1999
the  Company  purchased 159,000 shares of its common stock on the open market to
offset  the  number  of shares sold through the DRIP during the same period. The
Company  also purchased 162,000 shares of its common stock on the open market in
1997.
     The  Company  issued  246,000 shares, 1,276,000 shares and 26,000 shares of
its  common  stock  to the shareholders of businesses acquired during 1999, 1998
and  1997,  respectively.  Of  the  shares  issued in 1998, 905,000 were for the
acquisition of OMC which was accounted for using the pooling of interests method
of  accounting. See Note 3 of the Notes to the Consolidated Financial Statements
for  more  information  on  the  OMC  acquisition.
     The Company contributed 44,000 and 30,000 shares of Company common stock to
one  of  the  Company's  401(k)  plans  in  1999  and  1998,  respectively.
     In  August 1998, the Company sold 1,820,000 shares of its common stock in a
public  offering.  The  proceeds  of  the  offering  were  $26,153,000  after
underwriting  discounts  but  before expenses. The Company used the net proceeds
from  the  stock  issuance  to  repay  short-term debt and for general corporate
purposes.
     The  Company  issued five percent stock dividends in May 1998 and May 1997.
Earnings per share of common stock, cash dividends per share of common stock and
average  number  of common shares outstanding were restated to reflect the stock
dividends.

CUMULATIVE  CONVERTIBLE  PREFERRED  STOCK - In November 1999, the Company called
for  redemption  all  outstanding  shares  of  its $2.3125, Series A Convertible
Cumulative  Preferred Stock. Holders of the 6,168 outstanding shares of $2.3125,
Series  A Convertible Cumulative Preferred Stock had the option of receiving $25
in  cash  for  each  share  redeemed  or  converting  each

Page 52

SEMCO  Energy,  Inc.  and  Subsidiaries



share into 4.11 shares of the Company's common stock. 1,055 shares were redeemed
for  cash  and  5,113  shares  were  converted  to  common  stock.
     There  were  6,218  shares  of the Company's $2.3125 cumulative convertible
preferred  shares  outstanding  at  December  31,  1998.

CUMULATIVE  PREFERRED  STOCK  OF  SUBSIDIARY - In  November  1999,  the  Company
redeemed  all  outstanding  shares  of  the  Series  A,  B,  C, and D Cumulative
Preferred  Stock  of  its subsidiary, SEMCO Energy Gas Company. The Company paid
cash  of $105 per share to holders of the 31,000 outstanding shares of Series A,
B,  C,  and D Cumulative Preferred Stock. A premium of $155,000 was paid as part
of  the  redemption  of  the  Cumulative  Preferred  Stock  and  is reflected in
dividends  on  preferred stock in the Consolidated Statement of Income for 1999.

LONG-TERM  DEBT - In  April  1998,  the  Company redeemed all of its outstanding
8.625%  debentures  due  April  15,  2017  at  a redemption price of 104% of the
principle  amount  of  $23,548,000.  The  redemption  was  accomplished  using
short-term  debt.  Later  in 1998, the Company issued $30,000,000 of medium-term
notes  with  interest  rates  ranging  from 6.40% to 7.03%. In 1997, the Company
issued $60,000,000 of notes, half of which had an interest rate of 6.83% and the
other  half  of  which  had  an interest rate of 7.2%. The net proceeds from the
issuance  of  the  notes  were  used  to  repay  short-term debt and for general
corporate  purposes.
     The  Company  has  long-term and short-term debt arrangements which contain
restrictive  financial  covenants including, among others, limits on the payment
of  dividends beyond certain levels. The Company is currently in compliance with
all  of  the  covenants  in  these  agreements.
     There  are  no  annual  maturities  or  sinking  fund  requirements for the
Company's  existing  debt  over  the next five years, except for the maturity of
$30,000,000  of  6.83%  notes in 2002 and $55,000,000 of 8.0% notes due in 2004.


6.     SHORT-TERM  BORROWINGS

The  Company  maintains  unsecured  lines  of  credit  at  two  banks  totaling
$110,000,000.  The  outstanding  balances  owed by the Company on these lines of
credit  at  December  31, 1999, 1998 and 1997 were $84,600,000, $59,800,000, and
$71,000,000,  respectively.  Interest  on  all such lines are at variable rates,
which  do  not exceed the banks' prime lending rates. These arrangements are set
to  expire  during  2000  and  the  Company expects they will be renegotiated at
comparable  terms.  In  addition,  the  Company  has  a  $290,000,000 short-term
unsecured  bridge  loan  which  was  used  to  acquire  ENSTAR.  The
interest  rate  on  the bridge loan can range from 100 to 150 basis points above
the  London Interbank Offered Rate ("LIBOR"). The bridge loan matures on October
30,  2000.  Payments  of  $56,000,000 will be required on the six and nine month
anniversaries  of  the funding date (November 1, 1999) if the bridge loan is not
prepaid  prior  to  such  dates.  The  Company
also  has  a  note  payable in connection with the sale of its investment in the
NOARK  Pipeline  System  Partnership  ("NOARK")  (see  Note  15).
     Information  regarding these borrowings for each of the last three years is

7.     FINANCIAL  INSTRUMENTS

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.
     The  estimated  fair  values of the Company's long-term debt as of December
31,  1999  and  1998  are  as  follows  (in  thousands  of  dollars):

HEDGING ARRANGEMENTS - Refer to Note 8 for a description of hedging arrangements
and  their  fair  values.


8.     RISK  MANAGEMENT  ACTIVITIES  AND  DERIVATIVE  TRANSACTIONS

The  Company's  primary market risk arises from fluctuations in commodity prices
and  interest rates. The Company manages this risk through the use of derivative
instruments  and  limits  the use of such instruments to hedging activities. The
Company's  risk  management  policy  expressly  prohibits  the  utilization  of
derivatives for trading purposes. A derivative transaction is considered to be a
hedge  if  it meets the hedging criteria as outlined in SFAS 80, "Accounting for
Futures  Contracts."  Any changes in market value and gains and losses resulting
from  settlements  are deferred for these hedges until the hedged transaction is
complete.  If  a loss of correlation occurs in one of these derivative financial
instruments, such as (i) the market value of the hedge and (ii) the market price
ultimately  received  for  the hedged item are significantly different, the open
hedge  position  would  be  marked  to  market  and  gains  and  losses would be
recognized  in the statement of income currently. All derivative instruments are
marked  to market on the date of their termination, consistent with the guidance
for  hedge  activities. If the Company did not use these derivative instruments,
its  exposure  to  risk  would  be  greater.
     The  Company  is  subject  to  interest  rate  risk  in connection with the
issuance of variable and fixed-rate debt. In order to manage interest costs, the
Company uses interest rate swap agreements and exchanges fixed and variable-rate
interest payment obligations over the life of the agreements without exchange of
the  underlying principal amounts. The notional amount of the Company's interest
rate  swaps  was  $85,000,000  at  December  31,  1999.  The fair value of these
interest  rate  swaps  at  December  31,  1999  was  approximately  $2,720,000,
representing  the  net amount that the Company would receive if these agreements
were  terminated  on  December  31,  1999.
     The  Company  currently  does  not use derivative instruments to manage its
exposure  to  commodity  price risk since all of the natural gas requirements of
the  Company's  Michigan  gas  distribution  operations  are  covered  under the
TransCanada  supply  arrangement  and  ENSTAR's  natural  gas  requirements  are
primarily  covered  by  two  long-term  supply  arrangements and an RCA-approved
commodity  cost  pass  through  mechanism  to  its  customers.
     Prior  to  the  sale  of Energy Services in March of 1999 (see Note 1), the
Company  entered  into sales commitments which extended up to 60 months into the
future.  The  Company  also  utilized  derivative  financial  and  commodity
instruments,  including  futures  contracts, options and swaps, to reduce market
risk  associated  with  fluctuations in the price of natural gas. As of December
31,  1998  the Company had approximately $14,990,000 of futures contracts with a
fair  value of ($4,798,000), and $2,085,000 in commodity price swaps with a fair
value  of  ($654,000).  The  Company  also  had  approximately  $2,202,000  in

Page 54

SEMCO  Energy,  Inc.  and  Subsidiaries



net  deferred  gains, on contracts closed prior to December 31, 1998, related to
sales  commitments in the following month. The deferred gains and losses on both
the  open  and  closed  contracts  are  included  in  other  current  assets.
     The  Company  also hedged certain of its sales commitments with gas held in
storage.  At  December 31, 1998, the Company held approximately 3,829,000 Mcf in
storage  with  a  carrying value of $8,879,000, and approximately 888,000 Mcf of
outstanding gas loans owed to third parties with a carrying value of $2,286,000.


9.     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. The Company's
prepaid  pension  benefit cost at December 31, 1999 is net of an accrued benefit
cost  of  $788,000  related  to  the  SERP.
     On  December 31, 1997, the pension plans that cover primarily the employees
of  the  Company's  Michigan-based  gas  distribution  business  were amended to
provide  a  special  frozen  benefit to all employees with at least two years of
service on December 31, 1997. This special frozen benefit added both three years
of  service  and  three  years  of age to all eligible employees for purposes of
computing accrued pension benefits at December 31, 1997. In conjunction with the
amendment,  the  Company  offered  an  early  retirement program to all eligible
employees  with  at least two years of service on December 31, 1997. The program
was  open  from January 14, 1998 through February 27, 1998 and offered employees
the additional options of receiving either a lump-sum pension benefit payment or
an  immediate  annuity  commencing  April 1, 1998. One hundred and one employees
accepted the early retirement offer. As a result of the early retirement program
and  in  accordance  with  the provisions of SFAS 88, "Employers' Accounting for
Settlements  and  Curtailments  of  Defined  Benefit  Pension  Plans  and  for
Termination  Benefits",  the Company incurred a one-time gain which reduced 1998
net periodic pension costs by $1,641,000. This reduction was partially offset by
a one-time charge in the net retiree medical costs discussed below. In 1999, the
Company  also  changed certain actuarial assumptions and methods for its pension
plans.

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  1992,  the  MPSC issued a generic order addressing the adoption of SFAS
106 by utilities under its jurisdiction. The order allowed Michigan utilities to
adopt  SFAS 106 for accounting and ratemaking purposes, subject to a final order
in  a  general rate case and required the external funding for amounts recovered
in rates. The general rate case approved by the MPSC in October 1997 allowed for
such  recovery  of  retiree  medical  benefits, as discussed in Note 2. Prior to
getting  rate  approval  in  October 1997, the Company 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  division of the Gas Distribution Business under the jurisdiction
of  the  City Commission of Battle Creek was allowed a rate increase in December
1995  to recover its retiree medical costs. In 1999, the Company changed certain
actuarial  assumptions  and  methods  for  its  retiree  medical  plans.
     In  1999,  1998  and  1997,  the  Company expensed retiree medical costs of
$1,396,000,  $3,897,000  and  $2,471,000, respectively. The 1999 retiree medical
expense includes $899,000 of amortization of previously deferred retiree medical
costs. The 1998 retiree medical expense includes a one-time charge of $1,298,000
related  to  the  early  retirement  program  and  $899,000  of  amortization of
previously deferred retiree medical costs. The 1997 expense excludes $304,000 of
retiree  medical  costs  which the Company deferred and recorded as a regulatory
asset  in  accordance  with  the  MPSC's  order  discussed  previously.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


     The  Company  established  certain  Voluntary  Employee Benefit Association
("VEBA")  trusts  in  1997  to fund its retiree medical benefits and contributed
$2,500,000,  $2,339,000  and  $2,023,000  to  the trusts in 1999, 1998 and 1997,
respectively.  The  Company  also  partially funds retiree medical benefits on a
discretionary  basis through an Internal Revenue Code Section 401(h) account. In
1998  and  1997,  the  Company  made cash contributions to the 401(h) account of
$124,000  and  $508,000,  respectively. No cash contributions were made in 1999.
     The  following  two  tables  provide  reconciliations  of  the plan benefit
obligations,  plan  assets,  funded  status  of  the plans and components of net
periodic  benefit  costs  (in  thousands  of  dollars):

</TABLE>

     The  1999  postretirement  medical costs were developed based on the health
care  plan  in  effect  at January 1, 1999. As of December 31, 1999, the actuary
assumed that retiree medical cost increases in 2000 would be 7.0% for ENSTAR and
7.4%  for the Company's other businesses and prescription drug cost increases in
2000  would  be 7.0% for ENSTAR and 9.6% for the Company's other businesses. The
actuary  also  assumed that retiree medical costs and prescription drug costs at
ENSTAR  would  decrease  uniformly to 6.0% in 2002 and thereafter, and that such
costs  for  the  Company's  other businesses would decrease uniformly to 5.5% in
2005  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,  1999  by $4,862,000 and the aggregate of the service and interest
cost  components  of  net  periodic  retiree medical costs for 1999 by $391,000.

401(K)  PLANS, PROFIT SHARING PLANS AND THE EMPLOYEE STOCK OWNERSHIP TRUST - The
Company  has  defined  contribution plans, commonly referred to as 401(k) plans,
covering the employees of certain of its businesses or divisions. Prior to 1998,
the  Company  also  had an Employee Stock Ownership Trust ("ESOT"). During 1998,
the  Company  merged  the  assets  of  the  ESOT into a 401(k) plan that covered
approximately  the  same  group  of  employees. Under the provisions of the ESOT
prior  to  the  merger,  Company  contributions were discretionary. In 1997, the
Company contributed $400,000 in Company stock to the ESOT. Certain of the 401(k)
plans contain provisions for Company matching contributions. The amount expensed
for  the  Company  match  provisions was $716,315 and $491,000 in 1999 and 1998,
respectively.  Company  matching  contributions  were  not  required  in  1997.
     The  Company has profit sharing plans, covering the employees of certain of
its  businesses or divisions. Annual contributions are generally determined by a
formula which contains minimum contribution requirements. Profit sharing expense
was  $147,713  for  1999.  There was no profit sharing expense in 1998 and 1997.


10.     STOCK-BASED  COMPENSATION

At  the  Company's  1997  annual  meeting, the shareholders approved a long-term
incentive  plan  providing  for  the  issuance  of  up  to  500,000  shares  of
non-qualified  common  stock  options  over  the next ten years adjusted for any
subsequent  stock  dividends  and stock splits. 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. Additionally, pursuant to an executive employment agreement, the
Company  granted  30,000  common  stock  options during 1997. These options vest
three  years  after  the  grant  date 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. Fair value of the
options  was estimated at the date of grant using a Black-Scholes option pricing
model  with  the  following  weighted  average  assumptions:

     In  October  1995, the Financial Accounting Standards Board ("FASB") issued
SFAS  123,  "Accounting  for  Stock-Based  Compensation."  In  general, SFAS 123
recommends  that all stock-based compensation given to employees in exchange for
their  services  be expensed based on the fair value of the options granted. The
Company  has  chosen  to  continue  accounting  for  these  transactions  under
previously  existing  accounting  standards  as allowed in SFAS 123. However, if
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 below (in thousands of dollars, except for per
share  amounts):

11.     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,  warrants,  or  convertible  securities  ("dilutive
securities")  were  exercised.  Accordingly,  income  available  to  common
shareholders  is  also adjusted for any changes to income that would result from
the  assumed  conversion of the dilutive securities. The diluted EPS calculation

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


12.     BUSINESS  SEGMENTS

The  Company  adopted  SFAS 131, "Disclosure about Segments of an Enterprise and
Related  Information," during 1998. SFAS 131 established 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 that 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, extraordinary charges, changes in
accounting  method  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 are combined and
reported  as  one segment and referred to as "all other." The Company's propane,
pipelines  and  storage  business  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 this business
segment.
     The  Company  currently  operates  four  business  segments.  They  are gas
distribution, pipeline construction services, engineering services, and propane,
pipelines  and  storage.  The  Company sold the subsidiary comprising its energy
marketing  business  effective  March  31,  1999.  Refer  to  Note 1 for a brief
description  of  each  business  segment.
     The  accounting  policies  of  the 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.

13.     INVESTMENTS  IN  AFFILIATES

The  equity  method of accounting is used for interests in affiliates 20% to 50%
owned.  These  affiliate  companies  are  generally  involved  in  natural  gas
transmission, storage or associated operations. The Company records income taxes
on  its  share  of  undistributed  earnings  of these affiliates at the time the
earnings  are included in consolidated income. At December 31, 1999, the Company
held  the  following  interests  in  these  affiliates:

14.     COMMITMENTS  AND  CONTINGENCIES

CAPITAL  INVESTMENTS - The  Company's plans for expansion and improvement of its
natural  gas  delivery  system and its other diversified business properties are
continually  reviewed.  Aggregate  capital expenditures for property in 2000 are
projected  at approximately $50,000,000. In addition, the Company is planning to
incur  additional  expenditures  for  business  acquisitions  in  2000.

GUARANTEES - On  January  14,  1998, the Company sold its entire 32% interest in
NOARK.  The  sale  released  the  Company  from  all its NOARK guarantees, which
related  to  40%  of  NOARK's  debt.  See Note 15 for more information on NOARK.

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." Vehicle leases comprise a significant portion of total
lease  expense.  Leases  on 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.
     The  following  is a schedule by year of future minimum lease payments that
have  initial  or  remaining  noncancelable lease terms in excess of one year at
December  31,  1999:

<TABLE>
<CAPTION>
<S>      <C>               <C>           <C>
2000     $1,053,000        2003           $  458,000
2001        578,000        2004              381,000
2002        518,000        Thereafter      1,060,000
</TABLE>

Page 62

<PAGE>
SEMCO  Energy,  Inc.  and  Subsidiaries



     Total  lease  expense approximated $2,253,000, $2,164,000 and $2,092,000 in
1999,  1998  and  1997,  respectively.  The annual future minimum lease payments
shown  in  the  previous  schedule are substantially less than the lease expense
incurred in 1997 through 1999 because most of the vehicle leases at December 31,
1999  were  on  a month-to-month basis and were cancelable at any time. However,
management  expects  to  renew  or  replace  substantially  all  leases.

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  Gas  Distribution  Business 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 Gas Distribution Business 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 be
reasonably  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.

CONTINGENCIES - The  terms of certain of the Company's acquisition agreements in
1999  provided  for  additional consideration to be paid if certain results were
achieved.  The  former  owners  of  PinPoint  Locators,  Inc.  were  given  the
opportunity  to  receive  additional  consideration  based  upon  the  future
profitability  of  the PinPoint division. The former owners of K&B Construction,
Inc. were given the right to receive from the Company an additional sum of money
provided  the  future  results  of operations exceed certain targeted levels. No
additional  consideration  was  paid  in  1999.


15.     DIVESTITURE  OF  NOARK  INVESTMENT

The  Company  sold  its  entire  interest  in  NOARK to ENOGEX Arkansas Pipeline
Corporation  ("EAPC")  in  1998.  NOARK  is  a  302-mile  intrastate natural gas
pipeline  which  experienced  significant  cost  overruns  during  construction,
resulting in higher than expected financing costs. In addition, competition from
two  interstate  pipelines required NOARK to discount its transportation charges
to  attract  volumes  to  the  pipeline.  Even  with discounted rates, NOARK had
operated  at  less  than  65% capacity since its inception in 1992. As a result,
NOARK  continued  to  generate  losses  and  its  operating  cash  flows  were
insufficient  to  meet  principal  and  interest  payments  on  its  debt.
     In  1996,  the Company recorded a $21,000,000 after-tax non-cash write-down
of  its  general partnership interest in NOARK. In 1997, the Company reduced its
reserve  for  NOARK  by  $5,025,000  after-tax based on the terms of the pending
sale.  When  the  sale  was  finalized  in  1998, the Company incurred a gain of
$1,708,000  after-tax.
     Pursuant  to  terms  included in the sales agreement, the Company paid EAPC
$3,100,000  and  $9,200,000  in  April 1999 and 1998, respectively, and will pay
$800,000  in April 2000. The sale released the Company from all debt obligations
and  guarantees  related  to  NOARK. The Company will receive annual payments of
$842,000  from  EAPC  for  17  years  beginning  in  the  year  2004.

NOTES  TO  THE  CONSOLIDATED  FINANCIAL  STATEMENTS


16.     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.

We  have  audited the accompanying consolidated statements of financial position
and  capitalization  of  SEMCO  Energy,  Inc.  (a  Michigan  corporation)  and
subsidiaries  as  of  December  31,  1999 and 1998, and the related consolidated
statements  of  income,  changes  in shareholders' investment and cash flows for
each  of  the three years in the period ended December 31, 1999. These financial
statements  are  the  responsibility  of  the  Company's  management.  Our
responsibility is to express an opinion on the financial statements based on our
audits.
     We  conducted  our  audits  in  accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether  the consolidated financial statements are
free  of  material  misstatement.  An audit includes examining, on a test basis,
evidence  supporting  the  amounts and disclosures in the consolidated financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made  by  management,  as well as evaluating the overall
financial  statement  presentation.  We  believe  that  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, 1999 and 1998, and the results
of  their  operations  and  their  cash flows for each of the three years in the

RE:  Form  10-K  Report  for  the  Year  Ended  December  31,  1999


To  the  Board  of  Directors:

This  letter is written to meet the requirements of Regulation S-K calling for a
letter  from  a  registrant 's independent accountants whenever there has been a
change  in  accounting  principle  or  practice.

We  have  been  informed  that,  as  of January 1, 1999, SEMCO Energy, Inc. (the
"Company")  changed  its method of amortizing unrecognized gains (losses) on its
pension  plans and postretirement medical plans.  According to the management of
the  Company,  this  change  was made to provide a better means to recognize the
gains  (losses)  that  are  currently being deferred and recognized over several
years.

A  complete coordinated set of financial and reporting standards for determining
the  preferability  of  accounting  principles  among  acceptable  alternative
principles  has  not  been  established  by the accounting profession.  Thus, we
cannot  make  an  objective  determination  of  whether the change in accounting
described  in  the  preceding  paragraph is to a preferable method.  However, we
have  reviewed  the  pertinent  factors,  including  those  related to financial
reporting, in this particular case on a subjective basis, and our opinion stated
below  is  based  on  our  determination  made  in  this  manner.

We are of the opinion that the Company's change in method of accounting is to an
acceptable  alternative  method  of  accounting,  which,  based upon the reasons
stated for the change and our discussions with you, is also preferable under the
circumstances  in  this  particular  case.  In arriving at this opinion, we have
relied  on  the  business  judgment  and  business  planning of your management.

We  have  not audited the application of this change to the financial statements
of  any  period  subsequent  to  December  31,  1999.

Very  truly  yours,

Arthur  Andersen  LLP
