Detroit Edison Says Its Contract To Buy Wind Energy Approved By Michigan Public Service Commission

DTE Energy Co. (DTE: News ) said its largest contract to purchase wind power was approved by the Michigan Public Service Commission.

The approval sets in motion a 20-year agreement with Invenergy Wind that would result in 200 megawatts of new wind energy in Michigan.

The agreement – which represents a $1.1 billion commitment to renewable energy by Detroit Edison – paves the way for Invenergy Wind to install and operate a 30,000-acre wind farm near Breckenridge in Gratiot County, Michigan.

The new wind farm would host 125 1.6-MW GE wind turbines. The wind turbines are expected to be operational by late 2011 after a year of construction and would have the capacity to power nearly 54,000 homes.
