To make sense economically, utility-scale wind farms need at least thirteen-miles-per-hour average wind speeds at eighty meters (262 feet) above the ground. But the tests found local wind speeds averaged just 11.5 mph.
The idea of harnessing wind power to produce electricity and attract economic development has intrigued county officials since 2006, when it was first proposed by county commissioner Wes Prater. But no one knew whether wind speeds in the county would be sufficient.
So in 2007, the Board of Commissioners funded a one-year study by an Ohio consulting firm, North Coast Wind & Power. In partnership with the city of Ann Arbor, the University of Michigan, and the Chrysler Corporation, Washtenaw County officials created the Wind Power Washtenaw Project to promote the development of wind energy in the county.
In May 2008, an eighty-meter meteorological tower was installed at the Chrysler Proving Grounds--considered the most favorable spot for winds in the county. Hopes were high, but winds were not. According to the consultant's final report, posted on the county's website, "the wind resource observed from June 2008 to June 2009 would likely not support the development of a utility-scale wind farm."
