Integrated Resource Planning in the Carolinas
Customers in North Carolina and South Carolina desire a resource plan that supports communities and keeps rates as low as possible while ensuring continued economic competitiveness and access to increasingly clean energy. Duke Energy has made strong progress in the energy transition, retiring two-thirds of our Carolinas coal plants and reducing emissions by more than 40% since 2005. Our 4.5 million customers in both states benefit from a diverse, reliable mix of resources and already receive more than half of their energy from nuclear, hydroelectric and solar, making Duke Energy a national leader in carbon-free generation.
An IRP is a “road map” that helps support these goals by identifying potential plans for Duke Energy’s utilities in the Carolinas to meet future energy and demand requirements while considering the associated risks and benefits to customers. The IRP identifies supply and demand side resources needed to meet a utility’s projected demand over time to ensure reliable service to customers under certain conditions as projected at the time the IRP was prepared.
By Aug. 15, 2023, we will file an IRP with the Public Service Commission of South Carolina. By Sept. 1, 2023, we will file a combined Carbon Plan and IRP (CPIRP) proposal filing with the North Carolina Utilities Commission
In the first quarter of 2023, Duke Energy initiated engagement with stakeholders in North Carolina and South Carolina to discuss the development of Duke Energy’s upcoming resource plans in both states.

IRP Reference Information Portal
The purpose of this Reference Information Portal is to provide a central location for stakeholders to access meeting information, materials and relevant reference information related to Duke Energy’s IRP for Duke Energy Carolinas (DEC) and Duke Energy Progress (DEP) in the Carolinas.
In the first quarter of 2023, Duke Energy initiated engagement with stakeholders in North Carolina and South Carolina to discuss the development of the upcoming resource plans. The information gathered in this stakeholder process will inform the IRPs filed in both states.
This Portal contains all the presentation materials and Q&A from these engagement sessions – content will be updated as material becomes available. Under Additional IRP Resources, stakeholders will also find additional documents and links related to the IRP process in both states in addition to other resources pertaining to the filings.
