Question: Is there consideration for projects with existing IAs to bid into the 2026 RFP?
Answer: No. Projects with existing IAs are not eligible for bid into the 2026 RFP. The 2025 RFP allowed projects with existing IAs to bid into a limited, one-time early selection round and was meant to be a final attempt to allow projects that were eligible for tax credits to be selected in the RFP.

Question: Does Duke anticipate that the 2026 RFP and subsequent procurement cycles will follow the timeline outlined in the 2026 RFP Stakeholder presentation (with July proposal due dates), rather than the September due dates observed in prior RFP cycles?
Answer: Yes, we anticipate the 2026 RFP to follow the timeline outlined in the 2026 RFP Stakeholder presentation in order to keep the RSC in between annual cluster cycles. We do not yet have the timeline developed for subsequent procurement cycles.

Question: The RFP is ambiguous in projects that are qualified to bid based on Section III (g) of the RFP document. Can a project with a terminated PPA and a terminated IA bid for the RFP even if the PPA was executed in a prior RFP year between 2022 and 2025?
Answer: Market participants that have been selected in a prior RFP that have elected to terminate their Power Purchase Agreement and Interconnection Agreement (and pay any associated penalties) are eligible to submit a new Interconnection Request into the Resource Solicitation Cluster for 2026 and bid into the RFP. The project will be subject to all aspects of the 2026 RSC including the costs for the Interconnection Facilities and Network Upgrades identified in the 2026 RSC.

Question: For the 2026 RFP, will there be a new PV Curtailment portfolio view shared with market participants ahead of bids being submitted?
Answer: Please see the Excel file “Estimated PV Curtailment – 2025 CPIRP” showing the estimated curtailment in future years available in the 2026 Solar RFP:Q&A Documents page of this website. It includes two potential scenarios based on the results of the 2025 CPIRP modeling: the Recommended (NTAP) Portfolio and the High Load Sensitivity Analysis Portfolio. This information is subject to change due to several factors including shifts in projected loads, the pending merger of DEP and DEC, and future policy changes.

Question: The 2026 RFP does not include standalone storage. Are there any plans to include standalone storage in the 2027 RSC, or any other solicitations?
Answer: The Companies are currently planning on holding a 2026 Solar and Solar Paired with Storage RFP and also a 2026 SC Battery RFP. The latter will only seek standalone storage sited in SC, as required in the SC Energy Security Act (aka “Act 41”). This RFP website will include more information on the 2026 SC Battery RFP in the coming weeks, as the 2026 SC Battery RFP is still in development and the docket is still open in SC (Docket 2025-217-E).

Question: There is a standard advisory on Duke pre-apps that states: This project may be contingent on significant network upgrades exceeding one hundred million dollars that are currently assigned but will be necessary to allow new generation to connect in this region of the DEP system. These upgrades could take up to 5 years from start date to be completed. The project proposed in this pre-application cannot connect to the transmission system until required network upgrades are completed. How should we interpret this in submitting our bid pricing and online timeline?
Answer: Contingent network upgrades do potentially have an impact on the timing of the project reaching full network interconnection service, but the costs of those upgrades may be assigned to prior queued generators. Bidders with questions about a pre-application and its results should reach out to their account manager on the Renewable Integration Team.
