Fossil Gulch Wind Park Presented By Jeff Duff Vice President, Airstreams LLC Welcome

Hagerman, Id Fossil Gulch Seven (7) GE 1.5MW SLE Turbines Owned by Colorado & Santa Fe Real Estate Construction started in 2004 (Developed by Exergy Energy) Installation and Commissioning Completed 2005, First Utility Wind Facility in Idaho Operations and Maintenance (GE Wind Energy-Contract) Performance Management (Owners Representative Airstreams, LLC)

Fossil Gulch Facts – First Utility Scale Wind Power Facility in Idaho – Each 1500 kW Rated Power Would power about homes energy needs at full capacity – 80 Meter Tower Airbus A380 wing span is 80m – 77 Meter Rotor Diameter – Cut-In Wind Speed 3.5 mps Low Wind Technology – Currently two full time technicians – Turbines are remotely monitored on a 24 hr/7 day basis

Wind Farm Development Simplified Wind Resource – Minimum 5mps+ annual average wind speed, local data collection and site measurements, Transmission - Cost to build, access and development costs, Land – Private (Royalties) and Public (Lease), roads, infrastructure, facilities, Capital - $1 - $1.35m per MW installed 20 MW plus projects Power Purchaser or Market – 10 to 30 year contracts, Purchasers will seek cheapest and reliable source, trend in states like California is for Utilities to seek competitive bids due to development demand. Project Feasibility Issues – Biological Issues, Geological Issues, Local Issues (Noise, Visual), Flight Paths Zoning and Permitting Expertise Turbine Supplier – Turbine Purchase Agreements (Demand constraints have booked most OEM’s into Q1 2009) Turbine Operations and Maintenance – Cost, Warranties, Service and Engineering Support and track Record

O&M Challenges Wind turbines located in remote areas Lack of Trained Personnel due to strong demand by other companies Warranties – Fossil Gulch was purchased with a five (5) year parts and service warranty. New projects typically have two (2) year parts and service or “Parts Only” warranties. O&M Costs typically $5 to $8 per MW on 20MW and above projects.

Industry Trends

The U.S. wind energy industry installed 2,454 megawatts (MW) in 2006, an investment of approximately $4 billion, New wind farms boosted cumulative U.S. installed wind energy capacity by 27% to 11,603 MW, Expected growth for 2007 will add 26%, nearly 3,000 MW, One megawatt of wind power produces enough electricity to serve 250 to 300 homes on average each day.

Wind Resource Energy Potential THE TOP TWENTY STATES for wind energy potential, as measured by annual energy potential in the billions of kWhs, factoring in environmental and land use exclusions for wind class of 3 and higher. 1 North Dakota 1, Colorado Texas 1, New Mexico Kansas 1, Idaho 73 4 South Dakota 1, Michigan 65 5 Montana 1, New York 62 6 Nebraska Illinois 61 7 Wyoming California 59 8 Oklahoma Wisconsin 58 9 Minnesota Maine Iowa Missouri 52

Wind Energy Potential The total amount of electricity that could potentially be generated from wind in the United States has been estimated at 10,777 billion kWh annually—more than twice the electricity generated in the U.S. today. An estimated 31 billion kWh of Wind Energy will be generated in 2007, representing less than 1% of the potential.
