Wind Turbine
Project
University Need


Promote the sustainability and need for wind power in
Indiana
Using the wind turbine as a living laboratory

Possibilities




Design new/efficient turbine blades
Design new/efficient turbine engines
Study wind/weather on Purdue’s campus
Provide power to the intramural field lights and feed
power back into the Purdue power grid

Wind Turbine
Project
Goals of the Project



Get approval from Capitol Projects Council to
allow a wind turbine to be constructed
Fundraise money to construct a wind turbine on
campus
Make an educational component to go with the
wind turbine

Location Requirements

Height


Height of turbine and crane for installation restricted to 756 ft above sea level
Due to FAR Part 77



Electrical Tie-ins



Structure may not be more than 150 ft above airport elevation
Purdue Airport sits at 606 ft above sea level
Duke Energy lines west of McCormick Rd
Purdue power lines east of McCormick Rd
Wind Quality


Determine where the most consistent wind power can be found
Generally related to topography of region

Wind Turbine
Project
Site of Interest

Planned installation near the intramural fields





Site is close to the northwest substation
In close proximity to Purdue power lines
Higher elevation than surrounding area
Highly visible to Purdue students
Proximity to campus would allow for easier
educational access

Turbine Selection

Large Wind (≥ 1 MW)


Medium Wind (50 kW to 500 kW)



Due to siting restrictions large turbines will not be possible
More feasible with height restrictions
Less efficient than large wind
Small Wind (1.5 kW to 50 kW)


Much less efficient than larger sizes
Less attention demanded
