At 70 meters (230 feet), the average airpseed is 17.5 miles per hour.
Total construction and installation costs were approximately $2 million in 2004-2005.
The WCROC wind turbine is a 1.65 MW Vestas V82. It is 230 feet in height, with individual blade length of 135 feet.
Currently, UMM uses approximately 80% of the electricity produced. As some buildings on the UMM campus are unable to use the electricity produced by the wind turbine, the remaining 20% produced is put out on the grid and is purchased by Otter Tail Power Company.
In the first three years of production (March 8, 2005 - March 8, 2008), the wind turbine has produced 16 million kWh of electricity (approximately 5.33 million kWh per year). This is enough electricity to completely meet the needs of 550 homes.
The wind turbine generates electricity any time the wind is blowing between 8 and 50 miles per hour. Maximum electrical generation takes place between 26 and 50 miles per hour. At 50 mph, the wind turbine automatically shuts down to prevent damage to its components.
