Regulators of the US state of North Carolina have approved Duke Energy’s plan to replace two of its coal-fired units at Person County’s Roxboro plant with gas-fired combined cycle units. The units have a 1,360 MW of generation capacity and they are expected to enter service by 2029. The utility plans to retire the coal-fired Units 1 and 4 (380 MW and 711 MW, respectively) of the Person County Energy Complex and to continue operating Units 2 and 3 (673 MW and 698 MW, respectively) until 2034.
Duke Energy also plans to replace two of the four coal-fired units at the 2.1 GW Marshall power plant in Catawba County (North Carolina) with gas-fired generators that would have a total of 850 MW of capacity.
In November 2024, the North Carolina Utilities Commission (NCUC) approved the integrated resource plan (IRP) submitted by Duke Energy, which will notably see the utility add 3.6 GW of gas-fired capacity, 7 GW of renewables, 1.8 GW of pumped storage hydropower and 1.1 GW of battery storage by 2035 across the US State of North Carolina. In addition, Duke aims to have at least 17.5 GW of solar energy in its portfolio within the next 15 years.
