windmills Highway 90
The wind farm spans a stretch of farm fields six miles long and four miles wide, and is spread out over roughly 10,000 acres southeast of Interstate 90 three miles north and three miles south of Hwy 16, in Grand Meadow, Clayton, and Dexter Townships in Mower County. The amount of electricity generated is determined by the wind speed. Production starts at 9 mph and reaches full output at 27 mph. Three variable pitch blades then enable the turbine to hold the power output constant in high winds until they shut down at 56 mph to protect the blades during severe storms. To endure the Minnesota winters, they are equipped with heaters in various locations to enable operation down to -22F. However, the blades are not heated and occasional ice buildup will cause a temporary reduction of power output. • The height to the tip of the highest blade is 389 feet (slightly longer than a football field). • Each blade is a composite fiberglass material weighing 13,900 lbs. and is 122 feet long. • The base and access road of each turbine uses approximately 1 acre of farmland. • There are approximately 37 miles of underground fiber optic and electric cables connecting the turbines.
