On May 16, 2022, Duke Energy filed a proposed Carolinas Carbon Plan with the North Carolina Utilities Commission (NCUC)

According to a press release, Duke Energy’s proposal was shaped by significant stakeholder input, including engagement with more than 300 organizations from both North Carolina and South Carolina.

After evaluating the proposal, along with alternate proposals from intervenors, input from public hearings, and an extensive evidentiary hearing, the NCUC issued its final plan on January 4.

As outlined in North Carolina law, the final plan will be reviewed and adjusted every two years going forward.

The order requires Duke Energy to refresh its modeling — including impacts of the Inflation Reduction Act, Infrastructure Investment Jobs Act, and other future legislative changes and changing conditions — and file a new proposal with the NCUC by Sept. 1, 2023.

In August 2023, it will also file an Integrated Resource Plan with the Public Service Commission of South Carolina, which will take into account the carbon plan, the Inflation Reduction Act and Infrastructure Investment Jobs Act, and other factors relevant to resource planning.

Duke Energy’s Statement

"We believe this is a constructive outcome that advances our clean energy transition, supporting a diverse, 'all of the above' approach that is essential for long-term resource planning. We've already made incredible progress, retiring two-thirds of our aging coal plants in North Carolina and South Carolina and reducing emissions by more than 40% since 2005 – we will continue this ongoing work of lowering carbon emissions to reduce risk for our customers while balancing affordability and reliability.

"The communities we serve are already seeing the benefits of this transition. Customers in both states deserve a clean energy plan that supports communities and keeps rates as low as possible, while ensuring the continued economic competitiveness that the Carolinas depend on. We look forward to thoroughly reviewing the NCUC order and incorporating it into our resource planning, including our filings in South Carolina in August 2023."
