WILMINGTON, N.C. - For more than 40 years, the two red-and-white striped smokestacks at Duke Energy's L.V. Sutton Plant have served as a distinguishing landmark on the Wilmington landscape. In the coming weeks, the company will celebrate the plant's legacy and transform the landscape by beginning to mechanically remove the stacks.
The project is part of an effort to use more efficient energy sources and demolish retired coal plants.
"These colorful stacks represent more than just a local power plant," reflected John Elliott, Duke Energy district manager. "They are a symbol of our long history of powering the Cape Fear region and contributing to industrial growth in the Carolinas.
"As demolition of the structures begins, we will renew our commitment to providing customers with affordable, reliable energy from the new natural gas plant on site," he added.
As part of the demolition plan, Duke Energy's contractor will use a helicopter to place steel equipment on each stack to assist in removing the inner lining of the structures. Next, the contractor will attach a doughnut-shaped device to the top of each stack. Over the next few months, the equipment will descend the height of the 550-foot stacks, methodically removing sections of concrete at a rate of approximately five to 10 feet per week.
The Sutton coal plant began operating in 1954. Duke Energy retired the plant and began decommissioning the units after the company brought a new natural gas-fired unit into service at the same site in December 2013.
The Sutton Plant is one of nine retired coal plants across the Carolinas experiencing a major transformation through Duke Energy's decommissioning and demolition program.
Removing the smokestacks marks another milestone in the multiyear, complex process.

State issues draft permits necessary for coal ash removal
On July 2, the N.C. Department of Environment and Natural Resources issued draft wastewater and stormwater permits for the Sutton Plant.
The final permits, after a public comment period and approval by the state, are necessary for the company to begin drying and excavating coal ash from the site and moving it to fully lined, permanent storage locations.
Regulators have included additional provisions and more stringent limits in the draft permit to ensure water quality remains protected during the basin closure process.
