Illinois IGCC Project Receives Air Permit
LCG, June 6, 2007--The Illinois Environmental Protection Agency issued the air permit to Christian County Generation LLC for the Taylorville Energy Center, a proposed coal-fired, electric generating station using an integrated gasification combined cycle (IGCC) design. Construction may begin this year, and operations could commence in 2012.
As proposed, the Taylorville Energy Center would be a 630-MW electric generating station located in central Illinois. The plant would use Illinois Basin coal that is converted to syngas using a gasification process provided by General Electric.
The estimated project cost is $2 billion, and the State of Illinois pledged $500 million in low cost bonds to help finance the plant.
In July 2006, Tenaska announced that it agreed to acquire a 50% development-stage interest in the proposed Taylorville Energy Center from The ERORA Group LLC. The agreement called for Tenaska to jointly develop the remainder of the project with The ERORA Group.
There are a number of hurdles that remain in order for the project to proceed, including approval of the Illinois Clean Coal Program Law that enables developers to enter into long-term, regulated cost-based contracts with large Illinois electric utilities.
