Biennial Consolidated Carbon Plan and Integrated Resource Plans of Duke Energy Carolinas, LLC, and Duke Energy Progress, LLC
Docket No. E-7 Sub 1285

North Carolina General Statutes Section 62-110.9 (Carbon Plan Statute) directs the Commission to take all reasonable steps to achieve a seventy percent reduction in emissions of carbon dioxide in the State from electric generating facilities owned or operated by Duke Energy Carolinas, LLC (DEC), and Duke Energy Progress, LLC (DEP; collectively with DEC, Duke), from 2005 levels by the year 2030 and carbon neutrality by the year 2050 subject to certain discretionary limitations.

On December 30, 2022, in accordance with the Carbon Plan Statute, the Commission issued an Order Adopting Initial Carbon Plan and Providing Direction for Future Planning in Docket No. E-100 Sub 179 (Initial Carbon Plan). The Carbon Plan Statute directs the Commission to review the plan every two years after the adoption of the Initial Carbon Plan. The Initial Carbon Plan provided for the consolidation of the Carbon Plan and Integrated Resource Plan (IRP) processes (CPIRP, as consolidated) and required Duke to file its first proposed biennial CPIRP by no later than September 1, 2023.

On August 17, 2023, Duke filed its proposed 2023 CPIRP, which included three core portfolios, thirteen portfolio variants; and ten sensitivity analysis portfolios.

The Commission has scheduled five public witness hearings to receive testimony on Duke’s proposed 2023 CPIRP, as well as an expert witness hearing beginning July 22, 2024 for testimony and cross-examination of expert witnesses. There will not be an opportunity for public comments at the expert witness hearing, but the public is welcome to attend.
