Depends on the meters. My electric utility just replaced their old (circa 1999) smart meters which were one way broadcast with a new smart meter that's supposed to be two way capable. I didn't notice a lot of change at their data collection base station (which happens to be at the corner of my driveway), so I don't know if they already had a transmitter in addition to a receiver, or if it's small enough to fit in the existing equipment box or if they're using a different station.
