Illinois Senate Blocks Taylorville IGCC Coal Project

LCG, January 13, 2011--The Illinois Senate on Wednesday did not approve proposed rate subsidies for Tenaska's planned Taylorville power project by a vote of 18 to 33. The Illinois State House previously approved Tenaska's proposal by a vote of 63 to 50 on November 30, 2010.

Tenaska planned to commence construction on the $3.5 billion project in mid 2011. Without the Senate approval, Tenaska will need to reconsider its plans.

The project design incorporates Siemens AG's integrated gasification combined cycle (IGCC) technology to gasify Illinois coal for fuel to generate electricity in the 602-MW facility.

Tenaska expects the coal gasification process will allow over 50 percent of the CO2 produced to be captured, thereby reducing the carbon emissions from the facility. The captured CO2 would then be sequestered, either by storing the CO2 underground in Illinois or transporting the CO2 via pipeline to Gulf Coast states, where it would be injected into oil fields to enhanced oil recovery.

Tenaska plans to rely upon federal support for the project, which is sited approximately 200 miles south of Chicago in Christian County. Tenaska has stated that it is waiting for final approval on a $2.579 billion federal loan guarantee and that it plans to use a $417 million federal tax credit.
