DTE said it expects the majority of the renewable energy to come from wind resources.
Almost half, or 120 MW, would be operating by the end of 2012. The remainder would have to be commissioned by the end of 2014. The notice of intent to bid on this RFP is due by Jan. 21, 2011.
DTE plans to provide 10% of its power from renewable resources by 2015. As part of that plan, power will be purchased from a total of 600MW of renewables projects.
In September, Detroit Edison announced the approval by the Michigan Public Service Commission of a 20-year $1.1 billion power purchase agreement (PPA) with Invenergy Wind.
The deal, which was DTE's largest renewables PPA to date, was for wind farm to be built near Breckenridge in Michigan.
Another 600 MW of installed renewables capacity will be owned and operated by DTE. The company, which does not yet own any wind projects, has acquired easements on more than 75,000 acres of land in Michigan's Thumb region for the development of utility-scale wind farms.
