The Tennessee Valley Authority on Sept. 27 demolished two 500-ft-tall coal stacks and two boilers at the closed Widows Creek coal-fired power plant near Stevenson, Ala. A data center will be built on the 1,500-acre site where the 1,800-MW plant now is located. Small explosive charges were used to ensure that debris would be in manageable sizes and recyclable, said TVA. The federal power producer said that 100% of the metals will be recycled and concrete will be processed. The plant began operation in 1952 and was idled in October 2015. TVA said it has closed five fossil-fuel plants since 2012, with two more closures planned by the end of 2030.
