The Tennessee Valley Authority is blaming vegetation growth along a 161,000-volt line on Williams Island for at least two power interruptions to EPB on Tuesday afternoon.
About 32,000 homes and businesses from Red Bank to Graysville lost power, at least temporarily, when problems on a TVA line cut power to EPB. Both TVA and EPB rerouted power using smart grid technologies to limit the interruptions.
Jason Regg, a right-of-way manager for TVA, said the utility will dispatch a boat and tree-trimming equipment to Williams Island to clear vegetation that apparently interfered with the transmission line that delivers TVA-generated power to EPB.
Tuesday's power fluctuations and interruptions were the first for TVA from a falling tree or vegetation so far this fiscal year.
TVA has maintained 99.999 percent reliable delivery of power its its distributors for the past 14 years.
Chattanooga attorney Thomas Wyatt, a partner in Summers & Wyatt, was appointed Tuesday as one of the first eight judges that will help implement Tennessee's new workers compensation law, starting July 1.
The new administrative workers compensation court replaces the judicial review process for such claims and is designed to be quicker and less expensive.
