A Duke executive recently told state power regulators that the utility remains committed to building two new AP1000 reactors in South Carolina, but low demand growth will likely delay the project.Licensing activities for the new nuclear plant in Cherokee County, S.C., are ongoing, the Charlotte Business Journal quoted Duke Vice President Lloyd Yates as saying Wednesday. About $300 million has already been spent preparing for the $11 billion project. Duke had set a 2016 target date for completion of the first unit. That's been pushed back to 2022 in the interceding years, and Yates indicated it would likely be pushed back further because yearly load growth stands at a meager 1 percent.According to a fact sheet by Duke, it filed an application for a combined license to build the Westinghouse reactors in late 2007. Each unit will be capable of producing 1,117 megawatts.
