Question: Is a developer allowed to connect two Solar facilities at the same point of interconnection and file one application as a phased project?
Answer: No. The RFP and PPA do not contemplate “phased” projects, as there is one date that begins the term of the PPA and the facility is expected to perform at its as-bid MW and MWh. See Section III (Facility Eligibility Requirements and Proposal Tracks) for additional details.

Question: After reading Appendix O, it looks like we post a study deposit to enter the RSC cluster of $35,000 + $1/kWac. Then, to enter Phase I, we post 1X the study deposit. There is guidance on refundability / withdrawal penalties for those that withdraw after Phase I, but there’s no guidance on refundability / withdrawal penalties on the initial study deposit posted to enter the cluster. What happens to that study deposit our project is not selected to the “Short List” on 1/6/26?
Answer: If the interconnection request is withdrawn, any refunds of unspent deposit will be processed in accordance with the applicable procedures (Sections 6.3.3 of the NCIP; or Section 6.3.3 of the SCGIP ; or Section 4.7 of Attachment K to the LGIP).

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.
