Project goals: To determine the feasibility of a utility scale wind farm being constructed in the fields back campus.

Progress:

  • I have talked with Arlene DeBlanc about possible government grants
  • I have analyzed data from RP&L's tall towers survey.
  • I have analyzed data from the Indiana Tall Towers Wind Survey
  • I have analyzed the data from the weather station on the roof of Dennis
  • I have contacted numerous manufacturers for price quotes and other information on possible turbines
  • I have investigated various funding sources

Grant research

USDA Guaranteed Loans

  • B&I guaranteed loans
  • Cover up to 10 Million $ (up to 40 in some cases)
  • Guarantee 60-70% of the loans against default

Rural Business Opportunity Grant

  • Up to 50,000$ for economic development
  • Deadline for this year has already passed

EDA Public Works Grant

  • Average award of 9 Million $
  • Must show that project will help the local economy
  • Need to find or create comprehensive economic development strategy

Data Processing

RP&L Data

  • RP&L placed anemometers at the Kicks 96 tower
  • anemometers were placed at 50m and 100m, in sets of 2.
  • The data we received doesn't state where each anemometer is
    • After processing the first two sensors correspond closely (8.39 M/s, 8.31 M/s)
    • Sensor three reports a slightly higher windspeed, corresponding to a doubling of altitude (9.24 M/s)
    • Sensor four reports what appears to be an anomalously low average speed. (5.38 M/s)
  • Prior to processing all values about 30 M/s were removed
    • Removal was justified by the range of values (up to 8008 M/s) that failed sanity check
    • Removal does not affect power generated as there wind speeds above 25 M/s are not usable by the wind turbines.
    • Prior to removal of 300 M/s+ data sensors three and four had roughly similar average values
  • RP&L data shows a significantly higher windspeed than is estimated by satellite data (6.5 M/s)
    • This increased the estimated output by turbine by roughly one third.

Dennis Roof Data

  • Data was retrieved from the weather station on the roof of Dennis
  • Data ranges from January 5th 2000 to March 10 2009
  • The average wind speed over that time is 5.64 M/s
  • Assuming the sensor is at 10 M the 1/7th power rule extrapolates that the wind speed at 100M should be 7.84 M/s
    • 1/7th power law is: u/ur = (z/zr)?
    • With our numbers: (100/10)0.143=7.84 M/s
  • This indicates that the RP&L survey is more likely to be closer to the true wind speed than the satellite data.
