As temperatures fall, TVA raising Boone Lake water levels

With another cold snap expected tonight into Friday morning, the Tennessee Valley Authority has halted all non-emergency maintenance at its generation and transmission facilities — including Boone Dam — to reduce the risk to the valley’s power supply, agency spokesman Travis Brickey said Wednesday.

“We’re under a conservative operation alert, which means we’re curtailing any maintenance activities that could cause the risk that we would not be able to operate that facility,” Brickey said. “Part of the project at Boone is replacing the chains that control the head gate. The head gate must be open to let water into the penstock to allow the blades to turn the turbine and run the generator.

“If for some reason there was an accident or something happened while they were working on those chains so that we couldn’t open the head gate, then we couldn’t generate electricity at that unit.”
