  1. Campus Wind Turbine Project Morgan Lamping Ken Little Jennifer Turner

  2. Introduction • Started by the Boiler Green Initiative Club • Developed to create a wind turbine feasibility study

  3. Project Goals • Create an accurate, concise, and persuasive presentation on the feasibility and need of wind power at Purdue • Construct a functional and educational wind turbine on campus

  4. Siting Considerations • Height • Height of turbine and crane for installation restricted to 756 ft above sea level • Due to FAR Part 77 • Structure may not be more than 150 ft above airport elevation • Purdue Airport sits at 606 ft above sea level • Electrical Tie-ins • 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 in our desired siting area • Generally related to topography of region

  5. 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

  6. Future Siting Plans • Determine sites for wind data collection

  7. Turbine Options • Large Wind (1+ mW) • Due to siting restrictions large turbines will not be possible • Medium Wind (50 kW – 500 kW) • 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

  8. Redriven 20 KW • 20 kW rated power output @ 25 mph • 79 ft tall (ground to blade tip) • Optional 93 ft and 113 ft towers • Self-erecting • No need for cranes • Assembled on the ground and raised http://redriven.net/images_template1/20kw%20%20Farms3.JPG http://www.redriven.net/images_template1/20Kwcurve.jpg

  9. Redriven 20 KW • Electrical Output • 240 V /60 hz / 1 Phase • Electric Yaw Controller • Moves nacelle to maximize performance • Remotely controlled via web application • Dynamic Brake System • Controller uses yaw to reduce turbine speeds in high wind • Safety brake stops turbine if controller is malfunctioning or during major wind events • Sound • 61 dB at a distance of 25 feet

  10. Simple Payback Period • Total Cost of Turbine • Nacelle, Controller and Blades • $42,737 • Tower • $15,391 • Installation • Worst Case Scenario • $41,000 • Shipping • $9,000 • Environment/Siting Study • $5,000-10,000 • Sales Tax • $6000 • Total Cost • $119,000-125,ooo

  11. Simple Payback Period • Annual Maintenance Cost • ~$4,200/year • 5-year Blade Replacement • $5,170/5 years • Expected Lifetime • 30-60 years

  12. Simple Payback Period • Wind Turbine Performance • Estimated 5-7 m/s average wind • 120-168 kWh/day • 43,800-61,320 kWh/year • Increasing Energy Cost Model • Currently 5 cents/kWh • Assume rate increase of 5%/year

  13. Simple Payback Period • Complete Payback • 37 years • Average Energy Rates at Increasing Life Spans • 15 years: 20.39 cents/kWh • 30 years: 14.55 cents/kWh • 45 years: 12.61 cents/kWh • 60 years: 11.64 cents/kWh

  14. Carbon Offset • Total CO2 Offset Per Year • Offsetting coal at 2.1 lb/kWh (DOE/EPA) • 52.5 tons/year • Over 60 year life span • 3,150 tons

  15. Future Plans • This semester: • Options for transferring energy to the grid • Finalize construction and maintenance cost • Receive estimates from competitive turbine manufacturers • Fall 2009 • Begin work with contractors • Bright Idea Energy Solutions

  16. Educational Component • What? • Design an interactive educational kiosk with real time data • Tailored to all ages • Contents: • What a wind turbine is? • What it does and how it works? • The Process of the Project • The Benefits of a Wind Turbine and other Alternative Energies • Incorporate an educational dedication “plaque” on site • Create a website with the real time date from our turbine • How? • Working with the Engineering Education Department at Purdue • Meeting with Children’s Museum • Other Purdue Professors

  17. Future Plans • Brainstorm design ideas for kiosk • Visit and tour Children’s Museum in Indianapolis • Contact alternative energy faculty and environmental groups on campus • Create initial design plan for educational component • Rough sketches • General layouts • Relevant information

  18. Funding • Private funding options for infrastructure • Duke Energy • Locally operating wind energy companies • Organizational funding for educational component • Engineering Education Department • Department of Energy
