In Shift, Duke Energy to Recycle Coal Ash at H.F. Lee Plant

By Editors of Power Engineering

Duke Energy now has new plans for coal ash from four basins at the H.F. Lee Plant in Goldsboro, North Carolina.

The energy company will now excavate the ash and recycle it into various concrete producs.

Duke had originally planned to relocate the ash to a landfill in Lee County. However, Duke is now making additional investments in technology that can remove excess carbon from the coal ash and make it more suitable for concrete.

With this move, the majority of the six million tons of ash at the site will be processed by 2028. The remaining material will be relocated to a storage facility off-site, though Duke does not intend to construct a landfill onsite.

The utility announced it had recycled nearly two-thirds of the coal ash produced across its facilities in 2015. The latest announcement comes ahead of the January 1 North Carolina deadline for announcing locations for two coal ash recycling projects.

In October, the company announced plans to excavate and reprocess coal ash from the Buck Steam Station in Salisbury, N.C.

Duke said more than half of the concrete produced in the U.S. contains coal ash.
