Wind Energy=Fastest Growing Electric Generation Source

• Global- Climate Change, Carbon Constraints

• National- Climate Change, Energy Independence, Economic Growth

• State- Climate Change, Renewable Portfolio Standards, Economic Growth

• Local- Economic Opportunity

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

• 40-2.5 MW Turbines 67- 1.5MW Turbines

• Generates enough electricity for 30,000 average U.S. homes

• Permanent disturbed footprint is often less than 100 acres

• 200 construction jobs and 10-15 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 $50-100 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

• 4th 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 200,000-300,000 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
