NOTE: System purchases are the net MWh after subtracting off renewable purchases. Purchased electricity accounted for 11.8% 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.
