           CMS ENERGY ANNOUNCES FIRST QUARTER EARNINGS OF 51 CENTS PER
           SHARE, REAFFIRMS 2003 GUIDANCE OF 80 TO 90 CENTS PER SHARE

DEARBORN, Mich., May 8, 2003 - CMS Energy (NYSE: CMS) announced today
first-quarter net income of $79 million or $0.51 per share, compared to net
income of $42 million or $0.32 per share in the first quarter of 2002.

Ongoing net income (under non-Generally Accepted Accounting Principles) was $78
million or $0.50 per share, compared to ongoing net income of $79 million or
$0.60 per share in the first quarter of 2002. Management believes that ongoing
earnings provide a key measure of the Company's present operating financial
performance, unaffected by discontinued operations, accounting changes, net
asset gains or losses, or other items detailed in the attached summary financial
statements.

The $0.10 decrease in ongoing earnings compared with 2002 came despite stronger
utility earnings of $0.30 and a $0.25 gain from favorable foreign exchange
rates. These improvements were, however, more than offset by $0.33 per share of
2002 savings not repeated in 2003 and share dilution, as well as the absence of
earnings of $0.32 from businesses that have been sold.

Favorable weather and excellent power cost management improved first-quarter
results at CMS Energy's principal subsidiary, Consumers Energy. The utility
delivered 16.4 percent more gas and 5.6 percent more electricity in the first
quarter than a year earlier

Based on the first quarter results and the current outlook for the year, the
Company is reaffirming its earnings guidance for 2003 and expects:

         -        Reported net income will be roughly break even, dependent
                  largely on the timing and proceeds from planned asset sales.

         -        Ongoing net income will be in the range of $0.80 to $0.90 per
                  share.

Ken Whipple, CMS Energy's chairman and chief executive officer, said CMS Energy
has made good progress in executing its back-to-basics strategy over the past
year. He noted:

         -        CMS Energy and Consumers Energy completed $2.1 billion in
                  financings in recent weeks, boosting liquidity and financial
                  flexibility, cutting interest costs, and addressing debt
                  maturities through 2004 at the parent and well into 2004 at
                  the utility.

         -        Liquidity remains strong, in excess of the Company's cash
                  balance goal of about $400 million, split between the parent
                  and the utility.

         -        The Company is continuing its efforts to significantly reduce
                  operating expenses. The capital expenditure budget was cut
                  nearly 40 percent from 2001 to 2002 and will go down another
                  35 percent to 40 percent this year.




         -        The asset sales program remains on track, with about $3.7
                  billion in asset sales, including assumed debt, completed or
                  announced in 2002 and so far in 2003.

"The focus over the past year has been to increase our financial flexibility and
liquidity and implement our back-to-basics strategy. We're selling
underperforming and non-core assets. Our goal is to be a smaller, stronger
company with less business risk and more predictable earnings," Whipple said.
"The record shows we're making good progress, but there are still many
challenges ahead."

Looking ahead, Whipple noted that Consumers Energy has an important regulatory
agenda, with several key items before the Michigan Public Service Commission.
Those items include a request to securitize Clean Air Act expenses and other
costs, a gas rate increase case, and recovery of stranded costs linked to the
state's electric restructuring law.

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.
