New Power Plant Proposal for Wisconsin

LCG, December 2, 2004--Midwest Power, LLC has expressed renewed interest in developing a 225-MW power plant near the town of Beloit, Wisconsin. Further details regarding the project are expected shortly, following a meeting by town supervisors to review the proposal.

The announcement follows the Dane County Circuit Court decision issued Monday that the Wisconsin Public Service Commission's (WPSC) approval of We Energies' Oak Creek project violated state statutes and that the WPSC must start the approval process over. On Tuesday the PSCW, which approved the Oak Creek project in November 2003, unanimously voted to appeal the court decision. PSCW General Counsel David Gilles stated, "The Commission is very concerned about the effect of construction delays on future electric reliability in Southeast Wisconsin and on overall costs of the project."

The Oak Creek project, estimated to cost $2.15 billion, includes two 615-MW, supercritical pulverized coal units and would be the largest coal plant in Wisconsin.
