Site description

Duke Energy's Marshall Steam Station began operating in 1965 on the northwestern shore of Lake Norman in Terrell, North Carolina in Catawba County. It is one of the largest Duke Energy plants in the Carolinas and can generate up to 2,090-MW of electricity per year. In 2021, Duke completed construction that allowed 50% natural gas co-firing on units 3 and 4 and up to 40% natural gas co-firing on units 1 and 2. The company has planned a retirement date of 2035 for the facility, while qualifying that this date is only for planning purposes and could change. The Active Ash Basin and Industrial Landfill No. 1 in the station are regulated under the CCR rule. Both units are located northwest of the station.
