Detroit Edison, a unit of DTE Energy Company (DTE Energy), has signed a 20-year agreement with Heritage Sustainable Energy to purchase wind power and renewable energy credits (RECs).
RECs will be used to help the utility meet the state's renewable portfolio standard.
Heritage Sustainable Energy is also planning to install seven to eight wind turbines at a wind farm near Cadillac in the US in order to fulfil its agreement with Detroit Edison.
The agreement is the first signed by Detroit Edison following a new state law passed in 2008, which states Michigan's electric utilities should provide 10% of their power from renewable resources by 2015.
The wind turbines, which can generate around 15MW of renewable energy, are anticipated to become operational by late 2009.
