  1. Overview of Coal-Fueled Power Plants

  2. Agenda • What Is Coal? • Electricity from Coal • Why Coal? • Future of Coal SKS - 2

  3. Coal Plant – Jeffrey Energy Center SKS - 3

  4. US Coal Regions Sources: Energy Information Administration, Annual Coal Report, 2004, DOE/EIA-0584(2004) (Washington, DC, September 2005). SKS - 4

  5. Unit Trains Sources: University of Wyoming at smtc.uwyo.edu/coal/ images/coaltrain3.jpg SKS - 5

  6. Electric Generation from Coal • Conventional Combustion • Pulverized Coal • Circulating Fluidized Bed • Others • Gasification • Integrated Gasification Combined Cycle (IGCC) SKS - 6

  7. Coal Boiler Schematic SKS - 7

  8. US Generation by Fuel - 2003 Sources: US DOE EIA, Energy Information Administration, Form EIA-906, "Power Plant Report." SKS - 8

  9. Representative Emissions and Water Usage SKS - 9

  10. Representative Costs * Highly fuel cost dependent SKS - 10

  11. Typical Annual Demand Profile SKS - 11

  12. Typical Load Duration Curve SKS - 12

  13. The Future of Coal – Large Capacity Additions Sources: US DOE EIA, “Annual Energy Outlook 2006 (Early Release)" SKS - 13

  14. The Future of Coal - Emissions • Permittable Emissions Limits • SOx • CO2 • Mercury • Tighter limits increase capital and operating costs of conventional technologies. • Tighter limits provide opportunities for newer technologies, namely IGCC SKS - 14

  15. Future of Coal - IGCC Process Schematic SKS - 15

  16. The Future of Coal - IGCC Benefits Challenges Low Emissions and High Efficiency Low Emissions From High Sulfur Coal Lower Cost Mercury Removal Lower Water Use Lower Cost CO2 Removal Expect Less Resistance to Permitting Higher Project Cost Uncertainty in Cost and Schedule Commissioning Duration Availability Financing SKS - 16

  17. Summary • Coal Is a Sensible Choice for Current and Future Power Projects • Conventional Coal Is Currently More Proven and Lower Capital Cost • IGCC Has Advantages in Performance and Emissions Reduction Capabilities, Including CO2 and Hg • IGCC Expected to Face Some Obstacles to Market Acceptance in Short Term • IGCC Expected to Become Increasingly Popular Choice Over the Next 5 to 15 Years SKS - 17
