  1. AEE ANNUAL EXPO 2005Buena Park, February 16, 2005 Debenham Energy LLC Scott@Debenhamenergy.com 619-334-9541 Renewable Technologies Update A Progress Report Debenham Energy LLC

  2. AGENDA • Wind Energy • Wind Technology, Market and Regulatory Trends • California Opportunities for Distributed Generation (DG) • Local Success Story – Victorville Federal Prison • Innovative New Products Debenham Energy LLC

  3. GE WIND 1.5 MW Debenham Energy LLC

  4. Wind Turbines Continue to GrowLarger…Taller…More Productive Debenham Energy LLC

  5. Plan Now for Coming yet Larger WTGs Debenham Energy LLC

  6. A Typical Large Turbine has Multiple Subsystems and Controls Debenham Energy LLC

  7. World Wide Market Share Debenham Energy LLC

  8. Cost of Energy Trend 1979: 40 cents/kWh 2000: 4 - 6 cents/kWh Increased Turbine Size R&D Advances Manufacturing Improvements NSP 107 MW Lake Benton wind farm 4 cents/kWh (unsubsidized) 2004: 3 - 5 cents/kWh Debenham Energy LLC

  9. Wind Cost of Energy 12 10 8 Bulk Power Competitive Price Band Low wind speed sites COE (¢/kWh [constant 2000 $]) 6 4 2 High wind speed sites 0 2020 1990 2005 2010 2015 1995 2000 Motivation for Low Wind Speed Technology R&D • Current Situation • Wind viable at higherwind speed sites(Class 6 – avg. 15 mph @ 10m) • Limited high wind sites • Subsidies important • New Focus Needed • Shift to future industry needs • Broaden range of competitive opportunities • Eliminate the need for subsidies Debenham Energy LLC

  10. Acquiring Wind Least-Cost:Size Matters Assuming the same wind speed of 8.08 M/S, a large wind farm is more economical Source: AWEA Debenham Energy LLC

  11. Fossil Energy Resources Projected to Peak Soon Debenham Energy LLC

  12. World Wide Growth Debenham Energy LLC

  13. Tehachapi Area Wind ResourceCalifornia’s Largest Plausible Wind Energy Resource345 MW Connected to 66 KV SCE Grid380 MW Connected to 230 KV Private Transmission4,000 MW Plausible New Resource Stranded by Lack of TransmissionExpectation is SCE will now Build Major New Transmission Debenham Energy LLC

  14. California Opportunities for Distributed Generation (DG) Wind Debenham Energy LLC

  15. California DG Wind • Pro’s • Self Generation Incentive Program (SGIP) • $1,000 or $1,500 per kW? • Size increased to 5 MW? (1 MW eligible) • Moved from Level 1 to Level 3-R? • Funded $125m in 2005. Program through 2014 • Net Metering Law (1 MW) • High Electric Rates • “Progressive” State • Con’s • Limited Number of Large Loads in Windy Locations • Regulatory Environment (No Green Tag Sales!) • SGIP Funding for Wind affected by PV Funding Debenham Energy LLC

  16. Why does Wind Power make sense for Distributed Generation applications? • Technology improvements have dramatically lowered costs and increased reliability • US State and Federal incentive programs are making wind projects economically attractive • Much more economical than other renewable technologies in most places • Increasingly positive public perception is making siting and permitting easier Debenham Energy LLC

  17. Implementing Wind Power for Distributed Generation • Suitable Sites • Good Wind Resource • High Utility Power Cost • State Incentive Program • Permitable (allowed with zoning variance) • Connectable (Utility Interconnection Agreement) • Mid-Size Wind Turbine Availability • Mid-Sized wind turbine production in decline • Manufacturers are too busy with large projects Debenham Energy LLC

  18. Mid-Sized Wind Turbines for Distributed Generation Applications • Located at facility “after the meter” where retail power can be displaced • Reduces facility monthly utility energy bill • Sells excess power back to utility during off-shift and/or during windy periods. • May provide additional benefits: Visual evidence that the facility generates and uses green power Debenham Energy LLC

  19. Simplifying Wind Resource Assessments Debenham Energy LLC

  20. Wind Resource Assessments Tools Becoming More Sophisticated( Watts/M2 & TOU ) Debenham Energy LLC

  21. City Zoning / Permitting Debenham Energy LLC

  22. States with Favorable Incentives for DG Wind Turbines in the United States Debenham Energy LLC

  23. In Summary • Mid-Sized wind turbines can be economical in distributed generation applications given the right combination of factors: • Windy Location • State and / or Federal Economic Incentives • High Power Cost • Good Load Match with the Host Site (Net Meter) • Other benefits may be available as well • Green Image • Green Tags (REC’s/TRC’s) Debenham Energy LLC

  24. Federal Correctional InstituteVictorville, California A Hybrid Renewable Energy Efficiency Success Story Debenham Energy LLC

  25. Victorville Federal Prison Debenham Energy LLC

  26. Overview of Project Economics Debenham Energy LLC

  27. Debenham Energy LLC

  28. Challenges and Solutions • Challenge: • Accurately Assessing the Wind Resource. • Solution: • Assessment Confirmed Independently by a Private Meteorologist and NREL. Installed 2 MET’s to Determine Optimal Location. • Challenge: • Risk Responsibility – Wind Resource, Turbine Performance/Availability • Solution: • Agreed on TMY for Wind Energy. • Used Independently Verified Performance Data Less Expected Degradation. • Availability Independently Estimated. Response Times Written Into Maintenance Subcontract. Debenham Energy LLC

  29. Challenges and Solutions • Challenge: • Operational Costs for a Single Turbine • Solution: • Scope of Operations Responsibilities Shared Between Developer and Owner • Challenge: • Funding Long Term O&M • Solution: • Sinking Fund in Place for ‘Expected” Maintenance and Repair Costs in Order to Assure that Availability is as Predicted. • Challenge: • Tax and Environmental Benefits are Substantial but Hard to Incorporate • Solution: • Production Tax Credits, Accelerated Depreciation and REC’s (Green Tags) were not Included.
