Duke Energy customers to save $1.1 billion after NC reaches settlement following coal ash spill


RALEIGH, N.C. — Duke Energy customers will save more than $1.1 billion thanks to a settlement between the energy company and the State of North Carolina.

Attorney General Josh Stein said Monday, “This settlement is a win for every Duke Energy customer,” A.G. Stein said. “North Carolinians should not bear the full cost of cleaning up coal ash. Now we won’t.”


Stein says this agreement is also thanks in part to public staff and the Sierra Club.

“This agreement addresses a shared interest in putting the coal ash debate to rest as we work toward building the cleaner energy future North Carolinians want and deserve,” said Stephen De May, Duke Energy’s North Carolina president. “We were able to reach a balanced compromise that will deliver immediate and long-term savings to customers and provide greater certainty to the company over the next decade.”

For decades, Duke Energy had mixed coal ash from its facilities with water and stored the mixture in open ponds.

After a 2014 spill dumped 39,000 tons of ash from the Dan River plant in Rockingham County into the Dan River, lawmakers passed a law demanding the energy company end the use of coal ash ponds by 2030.

On April 1, 2019, the Department of Environment Quality ordered that Duke Energy excavate the remaining nine ash basins to make sure there are no future spills. The order specifically targetted the basins at Duke Energy’s Allen, Belews Creek, Cliffside/Rogers, Marshall, Mayo and Roxboro facilities.

Duke Energy issued a statement days later, arguing that excavation would put a financial strain on customers, suggesting the company would recoup the cost by increasing energy bills. The company announced that it intended to appeal.

The DEQ determined that excavation was the only option that met the requirements of the Coal Ash Management Act “to best protect public health,” specifically by disposing of the ash in a lined landfill.

The company described the DEQ’s order as “the most expensive and disruptive closure option possible,” adding that the department describes the basins in question as “low risk.”

Duke Energy, North Carolina’s Department of Environmental Quality and the Southern Environmental Law Center announced in January 2020 that six of the basins would be excavated with the ash moving to lined landfills.

DEQ touted the plan as the largest coal ash excavation in the nation’s history.

“North Carolina’s communities have lived with the threat of coal ash pollution for too long,” said DEQ Secretary Michael S. Regan. “They can now be certain that the clean-up of the last coal ash impoundments in our state will begin this year. We are holding Duke accountable and will continue to hold them accountable for their actions as we protect public health, the environment and our natural resources.”

The plan involved the excavation of almost 80 million tons of ash across six facilities and would bring an end to pending court cases.

Duke Energy praised the deal for reducing costs of the cleanup.

This plan allowed Duke Energy to leave the ash basins on which facilities and lined landfills were built at the Marshall Steam Station in Terrell and the Roxboro Plant. The company said the buried ash would be left covered and undisturbed.

“This agreement significantly reduces the cost to close our coal ash basins in the Carolinas for our customers, while delivering the same environmental benefits as full excavation,” said Stephen De May, Duke Energy’s North Carolina president. “We are fully focused on these important activities and building a clean energy future for the Carolinas.”

The company assured that the groundwater in those areas is safe and will be monitored.

“Drinking and recreational water supplies are safe now, and Corrective Action Plans will address groundwater at each site to ensure those supplies remain protected,” the company said.

The plan involved the excavation of almost 80 million tons of ash.
