  1. 2011 Governor’s Conference on Energy and the EnvironmentLG&E and KU Carbon Capture and Storage Project September 27, 2011

  2. LG&E and KU CCS Project Background • LG&E and KU Agreement with Department for Energy Development and Independence (DEDI) , September 2010 • Define a Project to Capture and Store CO2 from Coal Combustion • Significant Funding from DEDI with LG&E and KU Cost Share • Phase I Work to be Completed by June 30, 2011 • Components of the Project Definition • Capture Technology • Geology for Storage • CO2 Source and Site Constraints • Project Development Team • EPRI – Identify Promising Technology • KBR – Technology Selection and Process Engineering • KGS – Geological Evaluation • LG&E and KU – Project Management and Siting

  3. LG&E and KU CCS Technology Selection Process • Key Capture Technology Selection Criteria • Potential for Significant Cost Reduction Vs. Current State of the Art • Technology Not Currently Scheduled for a DOE Funded Demonstration • EPRI Identified 13 Potential Capture Technology Developers ADA* Jupiter Oxygen* 3H* Aker* MTR U of Texas Akermin* RTI U of Wyoming CAER* Siemens Babcock Thermo Babcock & Wilcox* * Provided Information Requested in EPRI Questionnaire

  4. LG&E and KU CCS Technology Selection Process • 7 of 13 Technology Vendors Responded to EPRI Questionnaire • Technology Screening Workshop in Early February of 2011 • Ranked Technologies Based on Predetermined Scoring Matrix • Short-listed 5 Vendors for Further Evaluation • Short-listed Technology Vendor Presentations in Late February of 2011 • Selection of 3H in March of 2011

  5. 3H Background • Small Research Driven Company Located in Lexington Kentucky • Self Concentrating Amine Process • DOE, EPRI, LG&E and KU are providing Funding for Bench Scale Work Through 1st Q 2014 (Independent from this DEDI/LG&E and KU CCS project) • Potential for Technology to be Ready for 50 MW Demonstration by 2016 • Additional Funding Required to be Ready for Demonstration

  6. Potential LG&E and KU Generation Sites Ghent Plant Trimble County Plant Mill Creek Plant E. W. Brown Plant KU Green River Plant LG&E 9/27/2011 6

  7. KGS Geological Evaluation of Sites KU LG&E

  8. LG&E and KU CCS Site Selection • Selected Brown as Preferred Demonstration Site • Best Geological Storage Potential • Avoids Interstate Legal Issues • New High Efficiency FGD for SO2 Removal • New NOx Control Under Construction • Sufficient Area Available for Demonstration Plant • Sufficient Process Cooling Water Available

  9. LG&E and KU Project Conclusions • Full Funding Commitments Required in Early 2013 to Complete Construction in 2016 • Estimated 50 MW Project Capital Cost with 20% Contingency • Approximately $140 Million or $2,800/KW • Approximately 2X the Cost to Construct Trimble 2 • Estimated Annual Operating Cost (excluding cost of replacement power) • Over $10 Million or Over $30/Ton Captured • To Proceed, the Project Requires Sufficient 3rd Party Funding
