Tennessee: Municipal broadband networks are only allowed in communities with an existing municipally-owned electric utility.
And even then, those municipalities are only allowed to offer broadband service to households and businesses in their service territory.
It’s important to note, however, that even with Tennessee’s preemption law, the state is home to one of the most celebrated municipal networks in the nation, EPB Fiber in Chattanooga. And in Knoxville, the city's electric utility is currently building what will be the biggest municipally-owned network in the U.S. (KUB Fiber) when it is completed.
