Renewable Energy and Carbon Credits

1. Renewable Energy and Carbon Credits Heath Norrick Manager of Renewable Energy Hoosier Energy REC, Inc.

2. Presentation Outline • Hoosier Corporate Profile • Carbon Credits Vs. Renewable Energy Credits (RECs) • Uses and Markets for Credits • Hoosier Efforts • Conclusions

3. Hoosier Energy REC, Inc. • Generation and transmission cooperative (G&T) • Approximately $1 billion in assets • Own & operate power plants & transmission assets • 2 coal plants (Merom @ 1,000 MW and Ratts @ 250 MW) • 2 gas plants (Lawrence @260 MW and Worthington @ 175 MW) • Own & maintain over 1,300 miles of transmission lines and 250 delivery points • Over 10 million megawatt-hours (MWh) sales in 2006 • Assisted with over $7B in new investment in central and southern Indiana in the last 15 years

5. Carbon Credits Vs. RECs Carbon Credits Renewable Energy Credits Only relates to the generation of electricity 1 MWh=1 REC RECs are defined at the state level currently for RPS purposes Debate over what types of generation produce RECs • Electricity generation is not necessary for production: Tons of CO2 reduced, avoided, or sequestered • Carbon Credits are defined by international protocols or voluntary markets • Cannot “double dip” with Carbon Credits and RECs from same source

6. Uses and Markets Carbon Credits Renewable Energy Credits Meet Renewable Portfolio Standards at state level Involves the electrical generation industry Allow companies/individuals to use green energy voluntarily 29 States now have RPS • Meet emissions limits in cap and trade systems • Involves multiple industrial sectors • Allow companies/individuals to offset carbon footprint voluntarily • EU ETS, Chicago Climate Exchange,

7. Landfill Gas Generation • Clark Floyd Landfill Generating Station • Add a third Engine by June 2009 • Increase total output to 3.6 MW

8. Biomass • Carbon neutral, baseload, generation • Potential around 15-30 MW • Utilizes local waste streams • Possible fuel mixing benefits at current coal facilities

9. Coalbed Methane • Current Project • Data Gathering/Modeling • Core Sampling • Purpose • Quantity and Quality of Gas estimation

10. Story County Wind Farm • 150 MW Total = 100 GE SLE 1.5MW Turbines • Hoosier has 25 MW • Developed by Florida Power & Light • COD November 15, 2008

11. Small Scale Wind & Solar In Operation: • Merom Education Center—15kW Wind, 3kW Solar • Victory Primary—1.8kW Wind, 3kW Solar • Decatur Switch Station—3kW Solar In Progress or Scheduled for Completion by 2009: • Worthington Primary—3-6kW Solar • Franklin Training Center—3kW Solar • Member Cooperative Wind & Solar Program • Hoosier will provide • a set financial contribution and project development guidance to REMCs wishing to install Wind or Solar Systems • REMC owned installations will have high community visibility for member education

12. Conclusions • RECs provide a vehicle for lowering carbon emissions in one sector of the economy • RECs monetize and track current carbon reduction while waiting for federal regulation • Carbon Credits and RECs share common purpose
