  2. Iowa Stored Energy Park “It’s The Responsible Thing To Do”

  3. (Animation from Web Site)

  4. We’ve found the geologic formation. The Department of Energy backs the project. Energy customers support the idea. Investors are coming on board. Where We Are:

  5. The Site Fits CAES Storage Requirements • Size • Permeability • Depth • Cap Rock • Porosity • Chemistry

  6. Located west of “downtown” Dallas Center, Iowa Within city limits, but still primarily rural Landowners & citizens coming on board

  7. Increased demand requires new resources Federal & State mandates on emissions likely Trends, challenges, and needs point to ISEP Why The Department Of Energy Backs ISEP

  8. Iowa Stored Energy Park “It’s The Responsible Thing To Do”What Energy Customers Say…

  9. Helps reduce/control MY household energy costs Uses a resource (wind) not being used enough Can decrease dependency on foreign energy Can decrease dependency on fossil fuels Is a clean and healthy source of energy

  10. Load Duration Curve 12 10 8 Demand MW 6 4 2 0 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% % Hours

  11. Energy Generation 12 Diesel GT 10 CAES Demand in MW ISEP Wind 8 Coal 2 Coal 1 6 4 2 0 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% % Hours

  12. Costs $/MWh in 10% to 50% Capacity Factor. 90 Compression 80 Fuel + VOM Fixed Costs 70 $/MWh 60 50 40 30 20 10 0 Coal-PC CC SC CAES

  13. 268 MW of CAES can save utility owners $5 Million per Year in cost of energy * Additional operational savings will come from better flexibility of CAES Black & Veatch: 200 MW CAES offers system benefits of $100 million/year How Much Would CAES Save? * Comparison: CAES to CC or Coal at 30% Capacity Factor

  14. $1,000,000 from Municipal Utility Funds $3,500,000 from Federal Funds Funding to date

  15. Leaving Research Phase Entering Development Phase Moving Forward Research Development Construction ending 2007 -2009 2009 - 2011
