Question: During the call on April 9, a “Tranche 1 report from 2024 RFP” was provided in chat. The provided pdf document actually appears to be dated 2019. Wondering if the wrong doc was attached? Is there a 2024 document that can be shared?

Answer: The link provided during the stakeholder meeting was to a 2019 CPRE report, not a 2024 RFP report. The latest RFP report from August 2024 is available at https://www.dukeenergyrfpcarolinas.com/RFP-Documents

Question: There was a request on the 1/29/2025 stakeholder call for comments to the pro forma documents. Which documents should stakeholders be using as the baseline?

Answer: 2025 RFP documents are not yet available. The Companies plan to use the 2024 RFP documents as a starting point, these are available on the IE’s website in the 2024 documents section - www.dukeenergyrfpcarolinas.com/2024-RFP-Documents. The slide deck from the 2025 Stakeholder Engagement session is also available on the IE’s website at https://www.dukeenergyrfpcarolinas.com/StakeholderMaterials.

2025-General

2025-GEN 00002
Published On: 04/15/2025

Question: We had a question regarding co-located projects submitting into the Duke RFP. If a co-located project is selected to enter the RSC, would the project need to submit two separate queue positions, or can it submit a single queue position for the entire project?

Answer: A “co-located” solar paired with storage project still has only 1 point of interconnection. A project that chooses to bid both solar-only and solar paired with storage will only submit one interconnection request, which is the same approach as the 2023 and 2024 RFPs.

2025-Interconnection

2025-INT 00002
Published On: 04/24/2025

Question: We are trying to understand all the financial requirements and corresponding refundability for the Resource Solicitation Cluster that will take place in parallel with the bid process. • What are the study costs / fees to enter Phase 1? • What is the refundability, if any, of the study costs during Phase 1? • How are the study costs remitted to Duke Energy. Is that cash? LOC? Bond? • As we understand it, if our project is invited to Short List, we enter Phase 2. Are there are additional study costs / deposits required to remain in RSC into Phase 2? o If so, what is the refundability of these additional study costs? • We understand that if our project is invited to Short List, we are to post a security in connection with the RFP. o How is that calculated? o What is the refundability of the security? o If Duke accepts our project, but requires us to offer a PPA price that is lower than we originally submitted, are we able to withdraw and keep our security? • Other than Network / Facility upgrade costs, are there any other financial requirements on the project to continue on through the RSC or the bidding process (other than what’s stated above)?

Answer: Please refer to the RFP Guidance document for the solicitation along with the applicable interconnection procedures for details regarding the financial requirements. The North Carolina Interconnection Procedures, the South Carolina Appendix CS and the Large Generator Interconnection Procedures are all available online. The LGIP is part of the Open Access Transmission Tariff and is posted on OATI OASIS.
