DTE Energy, Heritage start wind farm operation

DTE Energy and Heritage Sustainable Energy (Heritage) have started commercial operation of a wind fa

The wind farm was built after DTE Energy signed a 20-year agreement to purchase wind power and renewable energy credits from Heritage.

Anthony Earley, chairman and CEO of DTE Energy, said: "This is a way to provide our customers with renewable energy, but also to provide Michigan with sustainable economic development opportunities that have a meaningful impact on our customers' lives. We're focused on finding clean, cost-effective new sources of energy."

Heritage installed seven large-scale wind turbines at a 2,000-acre wind farm near Cadillac in order to fulfill its agreement with DTE Energy. The wind turbines, which are capable of producing about 14MW of renewable energy, are 403ft tall from ground to the tip of the upright blade.

DTE Energy expects the majority of its renewable energy to come from wind resources. The company has acquired easements on 75,000 acres of land in Huron county in Michigan's Thumb region for development of large-scale wind farms. The company also has two solar energy pilot projects that could produce about 20MW of power.
