   CMS ENERGY REPORTS STRONG THIRD QUARTER OPERATING PERFORMANCE; WRITEDOWN OF
                SOUTH AMERICAN ASSET RESULTS IN REPORTED NET LOSS

     JACKSON, Mich., Nov. 2, 2006 -- CMS Energy (NYSE: CMS) announced today a
reported net loss of $103 million, or $0.47 per share, for the third quarter of
2006, compared to a reported net loss of $265 million, or $1.21 per share, for
the same quarter of 2005.

     The 2006 third quarter loss stemmed primarily from an after-tax impairment
charge of $169 million, or $0.76 per share, for CMS Energy's 50 percent interest
in the GasAtacama power plant and pipeline. The non-cash charge reflects
increased uncertainty about the availability of natural gas to fuel the
720-megawatt plant in Chile.

     CMS Energy's adjusted third quarter net income, which excludes the
GasAtacama impairment and other items, was $40 million, or $0.18 per share, down
from $119 million, or $0.54 per share, for the same period of 2005. Adjusted
third quarter 2006 net income, without the expected reversal of previous
mark-to-market gains, was $70 million, or $0.31 per share, compared to $44
million, or $0.20 per share, for the same quarter of 2005.

     For the first nine months of 2006, CMS Energy had a reported net loss of
$58 million, or $0.26 per share, compared to a reported net loss of $88 million,
or $0.42 per share, for the first nine months of 2005.

     CMS Energy's adjusted nine-month net income, which excludes the GasAtacama
impairment charge and other items, was $69 million, or $0.31 per share, down
from $294 million, or $1.39 per share, for the same period of 2005.

     Adjusted nine-month 2006 net income, without mark-to-market impacts, was
$194 million, or $0.88 per share, compared to $163 million, or $0.77 per share,
for the same period of 2005.



     CMS Energy maintained its guidance for 2006 adjusted (non-GAAP) earnings,
excluding mark-to-market impacts, of about $1 per share. The Company noted that
its 2006 reported (GAAP) earnings will be substantially lower than its adjusted
earnings because of the expected reversal of mark-to-market gains and the
GasAtacama impairment charge. CMS Energy isn't providing specific reported
(GAAP) earnings guidance because of the uncertainties associated with the
reversal of mark-to-market gains.

     "Operational performance was strong during the quarter, especially in
meeting record high electric demand in Michigan in early August. Unfortunately,
the size of the GasAtacama impairment charge overshadows that fundamental
strength of our businesses and the outstanding efforts of our employees to serve
customers," said David Joos, CMS Energy's president and chief executive officer.

     CMS Energy is a Michigan-based company that has as its primary business
operations an electric and natural gas utility, natural gas pipeline systems,
and independent power generation.

Note: Adjusted (non-Generally Accepted Accounting Principles) earnings provide a
     key measure of the Company's present operating financial performance,
     unaffected by discontinued operations, asset sales, impairments, or other
     items detailed in these summary financial statements. Mark-to-market is a
     non-cash accounting adjustment that primarily reflects changes in the value
     of certain natural gas contracts.
