Consumers Energy is installing so-called Smart Meters in homes in parts of Michigan.  Spokesman Roger Morgenstern says they will give customers a way to accurately track their power useage. Under the system, individual customers also will be able to opt out of a Smart Meter if they choose.  Morgenstern says one of the biggest advantages of Smart Meters is they will help the Jackson-based utility pinpoint the scope of a power outage. He says if the power goes out, Consumers Energy will instantly know exactly which customers are in the dark, and they can repair the problem quickly.
