Demolition to begin on Jefferies Generating Station


MONCKS CORNER, S.C. – Santee Cooper awarded the contract for the demolition of Jefferies Generating Station near Moncks Corner to DEMCO Inc. DEMCO has started pre-demolition site work and is currently beginning general preparations, collecting and sorting materials and equipment, and setting up for asbestos abatement.

Demolition work begins this month, with the dismantling of Jefferies’ two 300 ft. stacks taking place from February through May. Because of the proximity of transmission lines, the hydroelectric station and the Tailrace Canal, the stacks will be disassembled mechanically from the top down using a hydraulic tool, called a stack muncher, for crushing and cutting the stacks’ concrete columns and brick liners.

Beginning in April, the turbine building will be dismantled, followed by the boilers and cooling towers from July through December. The warehouse area will be demolished in January 2018.

Crews are scheduled to work five days a week, 10 hours a day (during daylight hours), and noise from the site is expected to be minimal. Once the demolition is completed, the ground will be layered with soil, graded and covered with grass. The process is expected to be complete in the winter of 2018.

Jefferies Generating Station’s two coal-fired units were retired Dec. 31, 2012, and two oil-fired units were retired Oct. 1, 2015. The Jefferies hydroelectric units will continue to operate.
