7. Construction Phase: 428 new jobs $49.6 M to local economies Operational Phase: 15 local jobs $3.2 M/yr to local economies Wind energy’s economic “ripple effect” Construction Phase = 1-2 years Operational Phase = 20+ years Total economic benefit = $164.9 million New local jobs during construction = 495 New local long-term jobs = 21 to 30 Direct Impacts Indirect & Induced Impacts Totals (construction + 20yrs) As computed by K. Wadsack at NAU using the NREL “Jobs and Economic Development Impacts” (JEDI) model. Slide from the Wind Powering America update 2-09. Arizona – Economic Impacts from 100 MW of new wind development in Coconino County Construction Phase: 67 new jobs $32.7 M to local economies Construction workers, management, administrative, gas and gas station workers, etc. Operational Phase: 6 to 15 new long-term jobs $0.93 M/yr to local economies O&M Jobs, road maintenance, hardware store, supply parts, etc. Supporting businesses, such as contractors, equipment suppliers of subcomponents, grocery store clerks, retail sales, etc.

8. Wind Energy’s Economic impacts On-site direct, off-site direct, Indirect, Induced Indirect Impacts These are jobs in and payments made to supporting businesses, such as bankers financing the construction, contractor, manufacturers and equipment suppliers of subcomponents. Induced Impacts These jobs and earnings result from the spending by people directly and indirectly supported by the project, including benefits to grocery store clerks, retail salespeople and child care providers. Wind energy’s economic “ripple effect” On-siteOff-site Construction workers Management Administrativ e support Boom truck & management, gas and gas station workers, blades and towers & workers Cement truck drivers, road crews, maintenance workers Hardware store purchases and workers, spare parts and their suppliers Direct Impacts

9. Payments to Landowners: $2.5 Million/yr Local Property Tax Revenue: $4.6 Million/yr Construction Phase: 912 new jobs $133.6 M to local economies Operational Phase: 181 new long-term jobs $19.3 M/yr to local economies Construction Phase: 807 new jobs $92.7 M to local economies Operational Phase: 129 local jobs $15.6 M/yr to local economies Wind energy’s economic “ripple effect” Construction Phase = 1-2 years Operational Phase = 20+ years Total economic benefit = $924.3 million New local jobs during construction = 1,719 New local long-term jobs = 310 Direct ImpactsIndirect & Induced Impacts Totals (construction + 20yrs) All jobs rounded to the nearest 50 jobs; All values greater than $10 million are rounded to the nearest million Colorado – Economic Impacts from 1000 MW of new wind development
