                    CMS ENERGY REPORTS FIRST QUARTER RESULTS
                     AND REAFFIRMS ONGOING EARNINGS GUIDANCE

               JACKSON, Mich., May 6, 2004 -- CMS Energy (NYSE: CMS) announced a
reported net loss of $11 million, or $0.07 per share, for the first quarter of
2004, compared to reported net income of $82 million, or $0.52 per share, for
the same quarter of 2003.

               Ongoing (non-Generally Accepted Accounting Principles) net income
for the first quarter was $71 million, or $0.44 per share, compared to ongoing
net income of $81 million or $0.50 per share in the same period of 2003. This
year's milder weather more than accounted for the difference. The first quarter
results are consistent with the Company's 2004 ongoing earnings guidance of
$0.85 per share, up from $0.81 per share in 2003.

               Ongoing earnings provide a key measure of the Company's present
operating financial performance, unaffected by discontinued operations, asset
sales or other items detailed in the attached summary financial statements.

               The first quarter reported loss includes an impairment charge of
$81 million, or $0.50 per share, related to the April 2004 sale of the Loy Yang
power plant and coal mine in Australia. The charge, which was anticipated,
reflects the reduction in the value of the Australian dollar since 1997 when CMS
Energy invested in the project.

               Because proceeds from the Loy Yang sale were better than
projected, CMS Energy improved its 2004 guidance from a reported net loss of
about $0.50 per share to a loss of about $0.35 per share.

               Some recent CMS Energy highlights:

               -    Michigan's governor signed legislation that allows Consumers
                    Energy, CMS Energy's principal subsidiary, to continue to
                    offer its Appliance Service Plan. The state Legislature
                    approved the bill by overwhelming margins after thousands of
                    customers expressed their support for the program. About
                    160,000 residential customers are enrolled in the Appliance
                    Service Plan.

               -    The Palisades nuclear plant broke the continuous generating
                    record for Consumers Energy power plants and continues to
                    better the old mark of 345 days. On April 20, Palisades hit
                    the one-year mark for continuous generating.







               Ken Whipple, CMS Energy's chairman and chief executive officer,
said that the Company's transition to a smaller, utility-based company continues
to show results.

                  "We are maintaining our focus on operational excellence,
increasing our financial flexibility, and reducing debt," Whipple said. "Our
goal is to become a smaller, stronger company with more predictable earnings and
we're making progress toward that goal."

               CMS Energy is an integrated energy company, which has as its
primary business operations an electric and natural gas utility, natural gas
pipeline systems, and independent power generation.
