Raleigh, N.C.-  On August 17th, 2023, Duke Energy filed its combined Carbon Plan and IRP (CPIRP) proposal with the North Carolina Utilities Commission (NCUC). The Carbon Plan is mandated through HB951 and requires the NCUC to take ‘all reasonable steps’ to achieve 70 percent carbon emissions reductions from 2005 levels by 2030, and achieve carbon neutrality by 2050 using a least-cost approach.
