Suite  300
Farmington  Hills,  MI  48334


     SEMCO  Energy,  Inc.,  a  Michigan corporation (the "Company"), is about to
file  with the Securities and Exchange Commission, under Securities Act of 1933,
as  amended, a Registration Statement, Form S-3, registering 2,000,000 shares of
Common  Stock,  $1 par value (the "Common Stock") to be issued and sold pursuant
to  a  Direct  Stock Purchase and Dividend Reinvestment Plan ("the Plan").  Such
Registration  Statement  is  hereinafter  referred  to  as  the  "Registration
Statement"  and  the Prospectus which is a part of the Registration Statement is
hereinafter  referred  to  as  the  "Prospectus".

     I have examined the Registration Statement and have reviewed statements and
information  from officers and representatives of the Company and have made such
other  investigations  of fact and law as I have deemed necessary as a basis for
the  opinions  hereafter  expressed.

     As  counsel  for  the  Company  in  this  matter,  it  is  my opinion that:

     1.   The  Company is a corporation validly organized and existing under the
laws  of the State of Michigan with corporate power to carry out its business as
described  in  the  Prospectus.

     2.   When  the  Registration Statement has become effective, any applicable
state  security law has been complied with, and the Common Stock has been issued
and  sold  as  contemplated in the Registration Statement and in the Prospectus,
the  Common  Stock  will  be  legally  issued,  fully  paid  and non-assessable.

     3.   The  statements  made  in the Registration Statement under the heading
"Federal  Income  Tax  Matters"  are  correct.

     This  opinion  does  not  address  the  necessity,  if  any, for any person
involved  in  the administration or effectuation of the Plan, including the sale
of  Common  Stock  pursuant  to  the Plan, to register or otherwise qualify as a
broker, dealer, salesman, agent and/or other entity pursuant to the requirements
of  any  federal or state law (including without limitation state blue-sky laws,
the  Securities  Act  of  1933 and the Securities Exchange Act of 1934).  To the
extent  that  such  registration  or other qualification affects the validity of
this  opinion, this opinion is contingent on the proper and timely perfection of
such  registration or qualification.  Defined terms used herein, but not defined
herein,  have  the  meaning  given  to  them  in  the Registration Statement and
Prospectus.

     I  hereby  consent  to  the  filing  of  this  Opinion as an exhibit to the
Registration  Statement.

                                       Sincerely,

                                       Lawrence  J.  Gagnon
