Calpine's Fox Energy Center Begins Operations

LCG, June 7, 2005--Calpine Corp. announced yesterday that the Phase I commercial operations have commenced for the new, 300-MW, Fox Energy Center, located near Kaukauna, Wisconsin. Wisconsin Public Service Corporation has purchased about 150 MW of capacity from the combined-cycle power plant under a long-term contract that began June 1, 2005.

After acquiring the project from a subsidiary of MidAmerica Energy Holdings, Calpine initially planned to construct a 305 MW plant to provide 235 MW to Wisconsin Public Service Corporation. Last August, Wisconsin Public Service Corporation and Calpine announced that they had executed a contract to expand the project and provide for an additional 235 MW, ten-year power sales commitment for capacity, energy and ancillary services to begin on June 1, 2006.

The Fox Energy Center utilizes General Electric's advanced 7FB combustion turbines. Phase I of the project incorporates a single combustion turbine in a combined-cycle configuration with a heat recovery steam generator (HRSG), plus supplementary duct-firing, and a steam turbine generator. Phase II will add another combustion turbine and HRSG. With the completion of Phase II, which is scheduled by the end of 2005, the plant capacity will be increased to over 550 MW. The station can burn either oil or natural gas that is delivered via the ANR Pipeline.

According to Calpine, the project is being constructed under the Calpine Construct Plus model, whereby Calpine serves as general contractor for the facility. Calpine has obtained financing for the power plant through a $400 million, 25-year, non-recourse sale/leaseback transaction with affiliates of GE CommercialFinance Energy Financial Services.
