The MPSC has directed electric suppliers to report and compare the environmental and fuel mix characteristics of their electric supply against regional averages.

NOTE: Purchased electricity accounted for 17.22% of the electricity supplied by Detroit Edison during the period. The regional average fuel mix is used as a proxy for the actual fuel mix of certain electricity purchased by Detroit Edison because the actual fuel mix characteristics of that purchased electricity could not be discerned. The sulfur, carbon and nitrogen emissions are for the 12-month period January 2007 to December 2007.
