Illinois House Approves Taylorville IGCC Coal Project

LCG, December 2, 2010--The Illinois State House Tuesday approved Tenaska's proposed Taylorville power project by a vote of 63 to 50. The project will employ Siemens AG's integrated gasification combined cycle (IGCC) technology to gasify Illinois coal for fuel to generate electricity in the planned 602-MW facility.

The Senate is now expected to vote on the project this week. Tenaska plans to commence construction on the $3.5 billion project in mid 2011.

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.

The project, sited in Christian County, will utilize federal support. Tenaska stated that it is waiting for final approval on a $2.579 billion federal loan guarantee, and Tenaska plans to use a $417 million federal tax credit.
