Fundamentals of Wind Energy Development Wind Land Transmission Permits Market

Local Permitting: County Projects < 105 MW Studies/ Environmental Requirements Timeline Challenges/ Benefits

State Permitting: EFSC Wind Projects > 105 MW required, possible election on smaller projects Studies/Environmental Requirements Timeline Challenges/Benefits

Federal Permitting: NEPA Federal process guided by the National Environmental Policy Act, Federal Lands EIS or EA Challenges/ Benefits

Typical 100 MW Wind Farm A $250 million dollar average capital cost MW Turbines MW Turbines Generates enough electricity for 30,000 average U.S. homes Permanent disturbed footprint is often less than 100 acres 200 construction jobs and permanent jobs

Long Term Economic Benefits Local County Tax Revenue 10 direct high paying benefited jobs, ongoing operations and maintenance activities Lease and royalty payments paid to project landowners throughout life of project Indirect jobs created to support new industry Total local private sector economic activity generated during the life of the project will total $ million.

Short Term Economic Benefits 8-12 month construction period provides high intensity burst of economic activity Project construction: average of over 200 workers and a $10,000,000 payroll Total economic benefit of construction activity includes $20 million in revenue to local industries; $15 million in labor income and 350 direct and indirect jobs $10 million in construction goods and services purchased locally, resulting in close to $15 million worth of indirect economic activity Substantial benefit to local housing, lodging, restaurant and entertainment industries from out of area labor

Environmental Issues Wildlife : Birds, Bats, Owls Visual Impacts Noise 4 th generation wind farm technology has overcome many of the early drawbacks: greatly reduced noise, dangers to bird life, visual impact remain most difficult to mitigate impact of wind farms

Environmental Benefits Carbon Dioxide Reduction: a typical 100 MW wind farm reduces carbon production by 200, ,000 tons annually Sulfur Dioxide, Nitrous Oxide, Mercury, and Particulate free energy source Wind power uses no water, especially important for power generation in arid Oregon agricultural areas

Why is Wind growing in Oregon? Wind Transmission Land Economic Benefits Regulatory Environment Access to Markets Key factors that set Oregon apart in successful wind projects is a government and business climate conducive to project development, and large existing transmission infrastructure
