The Tennessee Valley Authority brought back one of its retired workers, Richard “Mac” Flowers, 91, to officially shut down the last operating unit at the Johnsonville Fossil Plant.
The 10-unit, coal-fired plant was the oldest in TVA’s fleet, as the first unit came online in 1951. Though it had a total capacity of 1,485 MW, only units one through four were still in operation. Units 5-10 were retired in 2015.
TVA officials said the closures were due to compliance with environmental regulations. The utility constructed the Johnsonville Combustion Turbine Plant, a natural gas-fired facility, adjacent to the Johnsonville Fossil Plant.
Another large coal closure is coming for TVA, as the utility will shut down the 741-MW coal-fired units at Allen Fossil Plant in Memphis by June and replace them with natural gas.
