Advanced Technology – What is “IGCC?”

• IGCC stands for “Integrated Gasification Combined Cycle.”

• It’s a combined-cycle power plant and a coal-gasification plant designed specifically to work with each otherplant designed specifically to work with each other.

• There are currently only two of these plants in the U.S.There are currently only two of these plants in the U.S.

Why IGCC?

• Use coal as fuel for highly efficient combined-cycle plant

• Clean coal technology - less NOx, SO2 and Mercury

• Less CO2 than conventional coal-fired power plants

• Greatest potential for future CO2 capture

The TRIG™ Gasification Process

• TRIG™ - Transport Integrated Gasification

• Product of more than 15 years research

• Developed at the Power Systems Development Facility (PSDF) in Wilsonville Alabama(PSDF) in Wilsonville, Alabama

• Sponsored by the DOE, Southern Company and KBRSponsored by the DOE, Southern Company and KBR

• Natural Mississippi resource

Why Lignite?

• Natural Mississippi resource• Estimated 4 billion

mineable tons• 160 million needed for Kemper

over 40-year plant life• Low commercial value Kemper IGCC• Low commercial value
