Duke implodes old powerhouse at retired Cliffside units

Duke Energy (NYSE: DUK) said Oct. 6 that it has imploded a shutdown part of the Cliffside Steam Station, where four coal units were retired earlier this decade as part of a clean-air deal that allowed the construction of a new coal unit (Unit 6) at the site.

Duke Energy demolished the station’s retired powerhouse as part of the company’s decommissioning program to modernize generation and dismantle older plants no longer in use. Duke noted that it has completed six implosion events at retired sites in the Carolinas since 2013.

The station began operating in 1940, with Units 1 through 4 retired in 2011. These original four units were replaced with cleaner, more efficient units. The company added Unit 5 in 1972 and Unit 6 in 2012. Both are now part of the James E. Rogers Energy Complex. 

Duke Energy Carolinas owns nuclear, coal-fired, natural gas, renewable and hydroelectric generation. That diverse fuel mix provides approximately 20,000 MW of owned electric capacity to about 2.5 million customers in a 24,000-square-mile service area of North Carolina and South Carolina. Headquartered in Charlotte, N.C., parent Duke Energy is a Fortune 250 company.
