Traverse City Light & Power Wind Generator
In June 1996, Traverse City Light & Power dedicated the first utility scale wind turbine generator in Michigan. The wind turbine is a Vestas model V-44, 600 kW generator and has a blade diameter of 144 ft. on a 160 ft. tower. The wind turbine has a variable blade pitch mechanism which can capture the most energy from winds. In average annual winds of between 14-15 mph the annual production from the wind turbine is estimated between 1.1-1.2 million kWh's which is enough electricity for approximately 200 average Traverse City homes. The capital cost of approximately $650,000 was partially funded by a $50,000 grant from the State of Michigan and the U.S. Dept. of Energy's State Energy Program.
