An implosion early Sunday morning brought down the plant’s power house and three boilers. A subsequent implosion on Monday brought down the remaining precipitator. The two events were the culmination of nearly two-years of preparation and mechanical demolition at the site.
Duke continues to excavate the coal ash basins at the Dan River site. Coal ash from seven decades of plant operations is currently stored in two ash basins and a dry ash storage area on site. Crews have so far removed more than 750,000 tons of coal ash by rail to a fully-lined landfill in Virginia. About half of the approximate 3 million tons of coal ash will be stored at this site, with the remaining ash stored in a new facility on plant property.
The 1949 Dan River plant was retired in 2012 when a new 620-MW natural gas-fired combined-cycle plant began commercial operation.
To date, Duke Energy has retired seven of 14 coal plants in North Carolina.
