Invenergy completes Michigan’s largest wind farm

Invenergy LLC, a closely held renewable-energy developer, began commercial operations at Michigan’s largest wind farm.

The 212.8-megawatt Gratiot County Wind Power Project has 133 General Electric wind turbines, Chicago-based Invenergy said Wednesday in a statement on its website.

DTE Energy Co., a Detroit-based power company, owns 69 of the wind turbines and Invenergy owns the rest. DTE is buying all the power from the wind farm under a 20-year contract, it said in a separate statement.
