CMS ENERGY CORP 8-K Report, Corporate Update (Nov 5, 2010)

Filed November 5, 2010For Securities:CMSCMS-PCCMSACMSCCMSD

Summary

CMS Energy Corporation, through its subsidiary Consumers Energy, reported a significant development on November 4, 2010, with an order from the Michigan Public Service Commission (MPSC) approving an increase in retail electric rates. This order authorizes an additional $145.7 million in annual revenue, based on a projected test year and a 10.7% rate of return on common equity, with the new rates effective November 5, 2010. Notably, Consumers Energy had previously self-implemented a rate increase of $150 million in July 2010. The MPSC's order requires a reduction of $4.25 million from this self-implemented amount and mandates a refund to customers for the difference between the self-implemented rates and the finally authorized rates, plus interest. The order also extends a pilot decoupling mechanism for another year, which adjusts rates based on weather-normalized sales performance. Additionally, the MPSC's decision addresses various other regulatory matters, including rate design, cost allocation, and the establishment of a trust for spent nuclear fuel disposal costs.
