The Michigan Public Service Commission approved a 20-year agreement for the wind project near Breckenridge in Gratiot County, Michigan.
It is the utility’s largest renewables contract, at a cost of $1.1billion. Invenergy expects the wind farm to be operational by late 2011.
The facility will use 125 1.6MW GE turbines and will be far larger than any of the state’s existing installations. Michigan’s wind capacity as of June was 143.4MW.
The state’s renewable energy standard requires utilities to generate 10% of their electricity from renewable power and energy efficiency by 2015, according to the Database of State Incentives for Renewables & Efficiency.
The standard also requires Detroit Edison to secure 600MW of renewable capacity by 2015.
The utility says that in total it needs to add about 1,200MW of renewables, mostly wind.
It plans to own about half of that capacity itself, and contract with independent power producers for the rest.
