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 Integrated Resource Plans (IRPs) for Duke Energy Carolinas (DEC) and Duke Energy Progress (DEP). In advance of filing our IRPs on Sept 1, 2020, Duke Energy engaged NC and SC stakeholders in a series of virtual sessions, intended to gather feedback as well as inform stakeholders about the IRP process. This Portal contains all the presentation materials and Q&A from these engagement sessions, as well as a final summary report from ICF, our third party facilitator. Under Additional Resources, stakeholders will find the official DEC and DEP 2020 IRP filing documents, and links to their associated attachments, in addition to other resources pertaining to the filings.
An IRP is a "roadmap" that identifies potential plans for a utility to meet future energy and demand requirements while considering the associated risks and benefits to customers. It identifies a cost-effective set of 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.* As noted below, the IRPs are prepared annually and are subject to change as market conditions, technologies and state and federal regulations evolve over time.
Duke Energy applies three primary objectives of increasingly clean, reliable, and affordable to guide its IRP planning process, and considers and compares resource portfolio alternatives to comply with policy objectives. With regulated service territories in both North Carolina and South Carolina, Duke Energy Carolinas and Duke Energy Progress each have a single IRP for both states that addresses the individual considerations of both state jurisdictions, resulting in four separate filings and associated regulatory processes. NC Commission Rules R8-60 require a bi-annual (every two years) IRP filing for DEC and DEP, with an annual update in the year between. SC Act 62 allows for similar timing requirements to North Carolina, allowing the Companies to maintain a bi-annual filing for both states. In both the biannual IRPs and the interim annual update reports, Duke Energy provides its latest 15-year forecast of native load requirements and a projection of supply-side and demand-side resources required to meet these load requirements. The IRPs for DEC and DEP are generally filed by Sept. 1st each year.

In the first quarter of 2020, Duke Energy initiated a process to engage stakeholders in North Carolina and South Carolina on our integrated resource planning efforts in both states. By engaging with stakeholders prior to the IRP filings, the company has an opportunity to listen and understand what is important to individual stakeholders, address their questions and determine how their feedback could potentially inform the IRP process within the 2020 requirements established under rule R8-60 in North Carolina and Act 62 in South Carolina.
To facilitate engagement, Duke Energy has contracted with ICF, who has also been helping with the company’s Integrated System Operations and Planning (ISOP) stakeholder engagement efforts. ICF’s engagement will ensure consideration of lessons learned and best practices from similar efforts across the industry. Duke Energy kicked off the IRP engagement process with targeted stakeholder listening sessions in February and March, followed by an IRP 101 virtual meeting facilitated by ICF on March 10. Duke Energy also worked with ICF to provide two IRP Forum engagement sessions for NC and SC stakeholders on March 17 and April 16, with a final follow up session with stakeholders on June 18, respectively. Topics addressed during these sessions included in both forums reflected those areas of greatest interest from stakeholders based on intervenor comments, listening sessions and pre and post-Forum surveys distributed by ICF.
Provided below are the associated materials from the two IRP Forums and one pre-filing Webinar that Duke Energy held with North Carolina and South Carolina stakeholders in 2020. ICF, which facilitated these forums, has provided a summary report for all of Duke Energy's IRP engagement activities leading up to and through the June 18 Webinar.
IRP 101, March 10, 2020
Co-led by ICF and Duke Energy, this webinar provides foundational information about the integrated resource planning process, including what it is, why it is relevant, national trends as well as Duke Energy’s approach to the process and current and regulatory requirements.
IRP Forum #1: March 17, 2020
This forum covered ICF's overview of national trends in IRP, Duke Energy's approach towards IRP, and breakout sessions on four main topics that stakeholders had identified as those of greatest interest: resource planning, carbon reduction, energy efficiency/demand response and load forecasting.
- Forum Slides
- Forum Recordings
This forum took a deeper dive on topics identified by stakeholders as most important to them. The three focus areas included: resource planning, carbon reduction, energy efficiency/demand response.
The focus of this webinar was on sharing what we heard from stakeholders and providing guidance on how Duke decided which input to incorporate into this year's IRPs.
The purpose of this webinar was to provide stakeholders a technical overview of what we filed in the DEC and DEP IRPs.
