ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

     The disclosures set forth under Item 2.01 hereof are hereby incorporated by
reference in this Item 1.01.

ITEM 2.01. COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS.

     On March 13, 2007, CMS Enterprises Company ("Enterprises"), a wholly owned
subsidiary of CMS Energy Corporation ("CMS Energy"), completed the previously
announced sale of its ownership interest in substantially all of its Argentine
assets and its northern Michigan non-utility gas gathering, processing and
pipeline businesses (the "Assets") together with certain related rights and
interests, for $130 million net to Lucid Energy LLC ("Lucid") whose financial
partners include Sociedad Argentina de Energia S.A., an Argentine company.
The $130 million of net proceeds were realized from a gross sale price of
$156.9 million, netted against approximately $26.9 million in cash which was
retained by one of the sold subsidiaries after receipt from Endesa, S.A.
("Endesa") in connection with Endesa's separate purchase of Enterprises'
ownership interest in the El Chocon plant in Argentina pursuant to a partnership
agreement right of first offer (as further described below). As a result of the
exercise of the right of first offer, the El Chocon plant that was originally
part of the Assets sold to Lucid was instead sold to Endesa. Immediately prior
to completion of the sale of the Assets, Enterprises and Lucid entered into
definitive purchase and sale agreements (the "Agreements") regarding the Assets.
The Agreements contain indemnifications, guarantees, and representations and
warranties that are typical for such sale transactions. The Agreements provide
that Enterprises' liability for breaches of representation and warranties will
be capped at the amount of $25 million for those relating to the Argentine
assets and $5 million for those relating to the Michigan businesses. Copies of
the Agreements are attached hereto as Exhibit 10.1, 10.2 and 10.3. A CMS Energy
News Release announcing the completion of the sale is attached as Exhibit 99.1.

     On March 9, 2007, CMS Energy announced that it had sold its interest in El
Chocon, an Argentine hydroelectric generating business to Endesa for $50
million. Of the $50 million, $23.1 million was paid to CMS Enterprises and the
balance was paid to one of the subsidiaries sold to Lucid Energy. Enterprises'
interest in El Chocon was originally part of the asset group that Lucid agreed
to purchase pursuant to a binding letter of intent. The letter of intent was
attached to CMS Energy's form 8-K filed on February 1, 2007 that is incorporated
by reference herein. However, Endesa had a right of first offer on Enterprises'
interest in El Chocon that it exercised. A CMS Energy News Release announcing
Endesa's exercise of its right of first offer for El Chocon is attached as
Exhibit 99.2

     As a result of the sales to Endesa and Lucid, CMS Energy realized cash
proceeds of $180 million, and will recognize an after-tax, non-cash loss of
approximately $160 million in the first quarter of 2007. CMS Enterprises will
maintain its interest in the TGN natural gas business in Argentina, which
remains subject to a potential sale to the government of Argentina or other
disposition. In recognition of Enterprises' commitment to sell its 23.5 percent
interest in TGN, CMS Energy expects to record an after-tax impairment charge of
approximately $140 million in the first quarter of 2007 to reflect the fair
value of its TGN ownership interest.

ITEM 9.01. FINANCIAL STATEMENTS AND EXHIBITS.

(B) PRO FORMA FINANCIAL INFORMATION

The accompanying unaudited pro forma condensed consolidated financial statements
reflect adjustments to the historical consolidated financial statements of CMS
Energy to give effect to the sale of interests in


                                        2



the Argentine and Michigan Businesses assuming the sale had been effective for
the periods indicated. The sales will be accounted for as discontinued
operations in accordance with Statement of Financial Accounting Standards No.
144, "Accounting for the Impairment or Disposal of Long-Lived Assets" and
Emerging Issues Task Force 03-13, "Applying the Conditions in Paragraph 42 of
FASB Statement No. 144 in Determining Whether to Report Discontinued
Operations".

Certain information and notes normally included in consolidated financial
statements prepared in accordance with accounting principles generally accepted
in the United States have been omitted pursuant to the rules and regulations of
the Securities and Exchange Commission governing pro forma information. The
unaudited pro forma condensed consolidated financial statements should be read
in conjunction with the consolidated financial statements of CMS Energy, as
contained in its 2006 Annual Report on Form 10-K.

The Unaudited Pro Forma Condensed Consolidated Balance Sheet assumes the sale of
interests in the Argentine and Michigan Businesses was consummated on December
31, 2006. Therefore, the loss on sale recognized at December 31, 2006 will
ultimately differ from the actual loss that occurred at the March 13, 2007 date
of sale. The Unaudited Pro Forma Condensed Consolidated Statements of Income
(Loss) assume the disposition occurred on January 1, 2004. The unaudited pro
forma condensed consolidated financial statements are presented for purposes of
illustration only, in accordance with the adjustments set forth below, and are
not necessarily indicative of the financial position or results of operations
that would have occurred had the sale been consummated on the dates as of which,
or at the beginning of the period which, the sale is being given effect, nor are
they necessarily indicative of future operating results or financial position of
CMS Energy.
