Why Wind?
• No air, water or soil pollution
• No waste to dispose of
• Renewable: we’ll never run out of fuel
• Lease payments to landowners
• Taxes to communities
• Purchase of local goods and services
• Land continues to be used as before

1. A computer turns
the rotor to face the
wind.
3. The blades turn a
shaft inside the
nacelle that spins a
generator that
makes electricity.
4. Power cables
inside the tower
take electricity
from the
generator to
underground
power lines.
2. The blades begin
to rotate when the
wind speed reaches
8 mph
How Wind Turbines Make Electricity
5. Underground
lines take the
electricity to our
substation. From
there, the
electricity goes
into overhead
power lines.

Developing a Wind Project
• Identify high wind potential areas based on regional maps
• Conduct site survey of property
• Install meteorological towers and measure wind 12-18 months
• Obtain required permits
• Conduct environmental studies
• Define boundaries and turbine locations
• Start construction 9-12 months
• Total time: 24-48 months

Environmental Responsibility
• Environmental assessments determine suitability of prospective sites
• Land and wildlife respected and protected during construction and operations
• Land restored after construction
• Recognized nationally for environmental leadership

Lee-DeKalb Wind Energy Center
• 145 GE wind turbines – 19 in Lee County and 126 in DeKalb County
• 217.5 megawatts
• Each turbine uses about one acre of land, including access roads
• Approximately 75 landowners involved in project
31
Lee-DeKalb Wind Energy Center
• Towers are 262 feet tall at the hub
• Each wind turbine has three blades
• Atop each tower sits a nacelle
• Nacelle houses the generator
• Operates in wind speeds up to 55 mph
• Best wind speed is 25 and 35 mph
32
Lee-DeKalb Economic Benefits Estimated over 30 Years
• $400 million direct investment
• $42 million expected in property taxes
• $50 million expected in landowner payments
• $50 million in salaries and benefits to about 20 employees
• $60 million expected in purchase of local goods and services over 30 years
