LCG, October 12, 2006--CMS Enterprises, a subsidiary of CMS Energy, announced yesterday that it has signed agreements with Peabody Energy to co-develop the Prairie State Energy Campus. The proposed electric generating station is located in Washington County, Illinois and is adjacent to the new Lively Grove Mine, which would supply low-cost coal directly to the plant. The plant is to include two, 800-MW units and is estimated to cost over $2.5 billion.
With the new agreements, CMS Enterprises and Peabody Energy will co-develop the project and each own 15 percent through a jointly owned limited liability company.

Illinois for the right to purchase an additional 6 percent equity share of
the Prairie State Energy Campus.
According to Peabody Energy, the agreements now give the project's partners the right to purchase a 53 percent equity ownership in the project. The agreements allow the cities of Columbia, Missouri; Princeton, Kentucky; and

The major permits necessary for construction of the Prairie State facility have been received, according to Peabody Energy.
