New IGCC Project Under Consideration in Indiana

LCG, March 10, 2005--Tondu Corp. is exploring the development of a new, coal-fired electric generating station in St. Joseph County, Indiana, and the project is under review by local officials. The 500-MW, advanced plant is based upon an integrated gasification combined cycle design that would be fueled by a mix of coal and petroleum coke. The project site under consideration is near New Carlisle and was previously targeted by Allegheny Energy Supply for the construction of a natural gas-fired, generating station.

The integrated gasification combined cycle (IGCC) process includes coal gasification, with the gas from the coal passed through a gas turbine to generate electricity. The hot exhaust gas from the turbine heats water to produce steam to power a steam turbine and generate electricity a second time. The IGCC plant design results in relatively high initial capital costs; however, its improved efficiency and reduced emissions are expected to improve long-term profitability and educe the environmental impact. With prices for the primary alternative fuel, natural gas, roughly more than twice the norm, the economic outlook for new coal plants is positive.

A number of other proposed coal generating stations have received grants from the Department of Energy to support advanced coal technology projects. Excelsior Energy, Inc. and ConocoPhillips will receive a $38 million grant for the development of a new, 531-MW, IGCC plant to be located near Hoyt Lakes, Minnesota. Orlando Utilities Commission (OUC) and Southern Power, the unregulated subsidiary of Southern Company, will receive a $235 million grant for the development of a 285-MW, advanced coal plant to be built at OUC's existing Stanton Energy Center near Orlando, Florida. Peabody Energy will receive a $19.7 million grant to demonstrate a technology to achieve ultra-low emissions at the proposed 300-MW, Mustang Energy Project located near Peabody's Lee Ranch Coal Company operations in New Mexico.
