Tennessee Wind Working Group
TNWWG provides outreach and education to rural, windy Tennessee communities on the benefits of harnessing wind energy.
•DOE Grant through State of TennesseeDOE Grant through State of Tennessee •TNWWG provides TNWWG provides education:education: Hosts at least 4 Free All Day Workshops for select communities in Tennessee
•TNWWG provides TNWWG provides communication:communication: Maintain communication between key stakeholders including USDA, TN State Energy Office, TVA, Local Community Officials, Wind Industry, Non-profits, Schools, Environmental Groups, and interested Tennessee citizens
•TNWWG provides TNWWG provides consultation:consultation:Facilitate TN Anemometer Loan program and assist TVA Wind Resource Assessment

• Wind energy displaces– Fuel– Emissions; carbon
• Wind provides a hedge against rising fuel prices (natural gas, coal)
• Wind is an energy source with limited capacity contribution other generation is also required
• Wind can be cost-competitive with other forms of generation and may reduce electricity cost
What are the benefits of wind energy to the power system?
Where is the Wind?

TVA Wind Energy Potential

Wind energy ~ 8,000 GWh
Hydro Generation (FY ‘06)•9,900 GWh Source: TVA website
While wind energy is the most abundant cost effective renewable energy source, there are no solid policies that attract wind developers to the state of TN or the TVA region.

Construction Operation
Gravel Access Road 14’-20’ wide
Gravel Crane Pad and Turnaround ~40’ x 60’
Subsurface Concrete Foundation~40’ - 50’ diameter
Turbine Pedestal16’ – 18’ diameter
Each wind turbine requires 0.5 - 2 acres. A typical facility requires only about 1%-3% of the total land under lease.
Land Use
Local Economic Impact
• Economic Development– 1MW wind = $1.5-2 million of
taxable equipment
• Landowner Land Lease Payments– $3,000-5,000 / MW / Turbine /Yr
• Jobs– Wind energy projects create a
few long term O&M jobs– Create many short term jobs
during construction
Case Study: South Dakota
40 MW (20 turbines) of wind energy installed. $100,000/yr in land lease payments $250,000/yr tax= 1/2 county school budget

Local/Community Ownership Options
Municipalities & Municipal Utilities Palmdale, CA; Algona, IA; Moorhead, MN
Rural Electric Cooperatives Farmer/Local Investors
LLCs, Investors Pools, Cooperatives; Kas Brothers • Minwind Energy
Schools Spirit Lake, Iowa • Carleton College, Northfield, MN
Tribal Communities Example: Rosebud, SD

Wind for Schools
• Community Education– The greatest impediment to wind energy
development is education. • Student Education and Training
– Supports the education and training of K-12 students in preparation for real jobs in the future.
• Utility Education– Utility becomes educated on variability,
interconnection, and operation of grid with wind turbines operating
• Reduced Energy Costs– School sees reduced energy savings
(depends on turbines size and wind resource)
Small (1-100 kW)
Example: Bergey XL at a Farm
• Ned Trivette• 65’ tilt-up tower• Batteryless, Grid-tie• Watauga County
Wind Turbines need Towers to access good Fuel

How to Buy A Wind-Electric System
1. Energy Analysis2. Efficiency measures3. Know your wind resource4. Select your turbine5. Select your tower and the rest
of the system• Grid-tie, no batteries• Off-grid, you need
batteries. • Good idea to add
SOLAR
Do it Right! • Be Safe• Maximize your resource
Financing Options
30% Federal Tax CreditNo ceiling. Businesses and individuals
40% TN Clean Energy Technology Grant Businesses only, capped at $75,000Need to conduct due diligence to qualify (wind map or anemometer)
25% USDA 9007 Grant (farms and rural small businesses)Historically for larger systems. Need conduct due diligence to qualify (wind map or anemometer)
