GE already makes smart meters with two-way communications between the consumer and the utility. There are a number of different networking paths that a utility can use to aggregate and transport information back to its data center. In its lab, GE is testing a WiMax system for communication from a home back to a utility. There are 140 million electric meters in the U.S. Converting a large number of them to smart meters will take about 10 years, GE executives said.
