The North Carolina Utilities Commission (NCUC) has 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 detail, Duke Energy plans to hold two solar tenders between 2025 and 2026, targeting 3,460 MW of solar to be commissioned by 2031, as well as to procure 1,200 MW of onshore wind by 2033. In addition, the NCUC order also approved Duke Energy conducting an advanced request for information process to study the development of up to 2,400 MW of offshore wind by 2035. The utility also plans to develop 1,834 MW of pumped storage hydropower by 2034 and 1.1 GW of BESS capacity by 2031.
As for gas-fired generation, Duke Energy plans to add four combustion turbines by 2030 (totalling 900 MW), as well as three CCGT units by 2031 (totalling 2,720 MW). The plan will also see Duke Energy retiring its remaining coal-fired generating units, which total more than 8,000 MW, by 2036. Finally, the approved plan will the conduction of early development activities associated with 300 MW of advanced nuclear generation to be commissioned by 2034 and an additional 300 MW to be ready by 2035.
Duke Energy Carolinas and Duke Energy Progress, subsidiaries of Duke Energy, currently own 34.5 GW of capacity, supplying electricity to 4.6 million customers in the US States of North Carolina and South Carolina.
