VIDEO: TVA demolishes 50s-era Johnsonville coal plant

NEW JOHNSONVILLE, Tenn. (AP) -- The Tennessee Valley Authority has demolished a coal plant that began generating electricity in the 1950s.

The implosion early Saturday destroyed a 600-foot smokestack and 10 boilers at the former Johnsonville Fossil Plant. The TVA says the Johnsonville plant, about 80 miles west of Nashville, was its oldest coal-fired plant.

TVA has retired six of its coal plants since 2012.
