Peabody Energy Signs Customers for Midwest Plant

LCG, July 20, 2004--A number of Midwest rural electric cooperatives and municipal agencies, including Indiana Municipal Power Agency, the Missouri Joint Municipal Electric Utility Commission, and Wolverine Power Supply Cooperative in Michigan, have executed a letter of intent with Peabody Energy to acquire partial interest in the Prairie State Energy Campus in Washington County, Illinois.

The agreement calls for the group to own about one-third of the 1,500 MW project, which includes coal reserves, a generating plant and output. The project is one of two, similar coal projects that Peabody Energy is currently developing in the Midwest. Peabody hopes to start construction next year and commence operations in 2008 or 2009.
