17 Rules of Thumb for Best-Bet Locations High elevation Relatively unobstructed fetch conditions Close proximity to existing transmission lines and substations to facilitate connection to grid OR proximity to large existing load Existing transmission lines have capacity for additional power

18 Wind Rose A wind rose is a graphic display of wind direction and magnitude. This wind rose data was collected at the University of Minnesota West Central Research and Outreach Center Turbine Location from 8/01/03 to 7/31/04 prior to construction of the turbine.
