The first step for planning a wind energy project is determining if you have enough wind to justify the expense of the system and the time and expense of operating and maintaining your equipment.
Wind Powering America provides high-resolution wind maps and estimates of the wind resource potential. The Department of Energy's Wind Program and the National Renewable Energy Laboratory (NREL) published a wind resource map for the state of Minnesota. The wind resource map shows the predicted mean annual wind speeds at 80-m height for commercial wind farms and Community Wind projects.
The Minnesota Department of Commerce provides wind maps developed for the Department by WindLogics, a Minnesota company that is at the leading edge of wind resource assessment using atmospheric modeling. These 2006 maps show the wind speed resources at 30, 80, and 100 meters, as well as capacity factor and energy production estimates for a 1.65 MW wind turbine at 80 meters.
