Project Experience: Rosiere Wind Farm, Wisconsin

The Challenge

Madison Gas & Electric needed compliance testing for a 17-unit wind farm located in Red River and Lincoln.

The Strategy

HMMH:

  • Continuously monitored A-weighted noise levels for one week, and compared the measured noise levels to limits contained within the Conditional Use Permit
  • Made tape recordings of the wind turbine noise and monitored both wind speed and direction
  • Demonstrated that for various wind conditions the wind farm was operating in compliance with local limits for both audible noise and low frequency noise, and that the turbines did not produce any pure tones
