Overview of the Kemper County IGCC Project UsingTranspor

t Integrated Gasification (TRIGTM)

RECS Program at the NCCC

June 09, 2011



Kemper County IGCC Project Overview 2x1 Integrated Gasification Combined Cycle (IGCC)

– 2 TRansport Integrated Gasifiers (TRIG™) – 2 Siemens SGT6 - 5000F CTs – 1 Toshiba Steam Turbine (Tandem Compound Double Flow) – 582 MW peak and 524 MW on syngas – Heat Rate 11,708 Btu/kWh (29.5% HHV Efficiency w/ CO2

control and 40+% moisture coal) – Selexol for H2S and CO2 removal – 65+% CO2 capture (~800 lb/mWh emission rate)

– Mine Mouth Lignite Owner & Operator: Mississippi Power Over $2 billion capital investment Commercial Operating Date: May 2014 Use treated effluent from Meridian as makeup water By-Products (TPY)

– ~3,000,000 - Carbon dioxide used for EOR – ~135,000 - Sulfuric acid – ~20,000 - Ammonia

TRIGTM Attributes / Advantages Simple, well established design

– Based on technology in use for 70 years

Either Air- or Oxygen-blown – Air for power

– Oxygen for liquid fuels and chemicals

High Reliability Design – Non-slagging design:

Provides 10-20 year refractory life,

Eliminates black water system

Provides non-fouling syngas cooler operation – No burners to fail and be replaced

– Dry dust removal eliminates gray water system

Lower Fuel Costs – Coarse, dry coal feed allows:

Fewer, lower power pulverizers, and

Less drying than other dry-feed gasifiers

– Cost-effective using high moisture, high-ash, low rank coals(PRB and lignite).

Excellent Environmental Performance – Lower water use compared to pulverized coal (PC)

– Excellent emissions performance

– Easier to permit compared to PC

– Lower cost carbon capture compared to PC
