Duke Energy chief executive Jim Rogers says his company won't build any more coal-fired power generators unless they have the potential to capture and sequester carbon emissions.
Rogers said carbon-sequestration, a process that stores carbon dioxide underground, won't work in the Carolinas, so the utility is only considering future coal-fired plants elsewhere.
Those remarks came two weeks after the Charlotte-based utility won final approval from state regulators to build an 800-megawatt coal-fired unit at its Cliffside plant.
Rogers defended the environmental impact of the project, noting that the company plans to shut down four smaller coal-burning units, all built in the 1940s, as part of the upgrade at Cliffside.
He said the $2.4 billion project is a transitional step as the industry works toward a low-carbon world.
