One of the nation’s only gigabit networks is now the communications force behind a new smart grid completed last week in Chattanooga, Tennessee. The utility company EPB installed its last IntelliRupter last Tuesday to finish automating its power distribution network. That means if the community suffers a power outage anywhere, EPB can re-route power automatically to continue the flow of electricity. The utility company isn’t the only one getting aggressive with smart grid technology, but it does find itself on the leading edge of communications networks. The same fiber infrastructure that underlies Chattanooga’s heralded gigabit Internet service also drives the region’s utility communications.
