1 This presentation contains "forward-looking statements" as defined in Rule 3b-6 of the Securities Exchange Act of 1934, as amended, Rule 175 of the Securities Act of 1933, as amended, and relevant legal decisions. The forward-looking statements are subject to risks and uncertainties. They should be read in conjunction with "FORWARD-LOOKING STATEMENTS AND INFORMATION" and "RISK FACTORS" sections of CMS Energy's and Consumers Energy's Form 10-K for the year ended December 31 and as updated in subsequent 10-Qs. CMS Energy's and Consumers Energy's "FORWARD-LOOKING STATEMENTS AND INFORMATION" and "RISK FACTORS" sections are incorporated herein by reference and discuss important factors that could cause CMS Energy's and Consumers Energy's results to differ materially from those anticipated in such statements. The presentation also includes non-GAAP measures when describing CMS Energy's results of operations and financial performance. A reconciliation of each of these measures to the most directly comparable GAAP measure is included in the appendix and posted on our website at www.cmsenergy.com. CMS Energy expects 2010 reported earnings to be about the same as adjusted earnings. Reported earnings could vary because of several factors. CMS Energy is not providing reported earnings guidance reconciliation because of the uncertainties associated with those factors.

|  | ELECTRIC RATE CASE U-16191* |  |

On January 22, 2010, Consumers Energy filed an application with the Michigan Public Service Commission seeking an increase of $178 million in its electric generation and distribution rates based on a test year of 12 months ending June 2011. On June 10, 2010, the MPSC staff filed a recommendation of $90 million based on a 10.35% ROE. The Staff suggested that its recommendation be adjusted upward by $25 million if the Company’s requested economic development sales tracker is not adopted by the Commission. The Staff also suggested that cap ex placed in service in 2011 be deferred for future recovery, rather than included in customer rates at this time. The Company plans to self implement a rate increase of $150 million, and filed a tariff sheet supporting this increase on July 13. The Commission approved the Company’s request and the self implemented rate increase will become effective on July 22, 2010. Below is a comparison of the Company’s self implemented amount to the MPSC Staff’s filed position.

|  | GAS RATE CASE U-16418* |  |

On August 13, 2010, Consumers Energy filed an application with the Michigan Public Service Commission seeking an increase in its gas delivery and transportation rates based on a 2011 test year. The Company requests an authorized ROE of 11%, and proposes a full decoupling mechanism, including weather. If approved, this request would add about $2.95 per month, or about 3.4%, to the typical residential customer’s average monthly bill. The $55 million revenue deficiency is detailed below.
