By March, DTE had replaced 7,000 out of 150,000 electrical meters in the Ann Arbor area—gas meters get an add-on module—at no cost to the customer, says company engineer John Jamerson. DTE notifies customers by snail mail three weeks in advance, and the switch takes just five minutes, but during that time, there’s no electricity. So Jamerson recommends that customers who own super sensitive equipment or—here’s the big one—happen to be on a life support system give a heads-up to the power company before they arrive.
