Question: Will projects that are already in the DISIS study process be allowed to participate in the upcoming RFP?
Answer: In this process, DESC and CRA are developing a Competitive Procurement of Renewable Energy (CPRE) program in accordance with the requirements outlined by the Public Service Commission of South Carolina in Order No. 2023-550 for Docket No. 2022-238-E. However, projects that are in either a past or then current DISIS study process are expected to be allowed to participate in future CPRE RFPs as long as they are still active in their respective queue.

Question: How will projects that propose to use Surplus Interconnection Service be evaluated in Section 3.3.1 of the Evaluation Criteria Appendix? Use of this service at a DESC owned power plant can provide expedited, low-cost interconnection service outside of the DISIS process. Would bids with projects eligible to use this interconnection service, subject to the approval of DESC, still be deducted 150 points since an existing queue position at the time of bid submittal is not feasible?
Answer: Any proposal that seeks to use Surplus Interconnection at any of DESC’s existing generation facilities by a third-party owned project will not be evaluated. However, Surplus Interconnection will be evaluated at any site for an existing third-party transmission customer of DESC. The same goes for Generator Replacement (whereby a customer may be able to replace a facility up to its existing interconnection rating in an expedited manner).

Question: How is Dominion planning on handling curtailment? Previously this was handled by when projects entered the serial queue and the last projects were assigned the most curtailment. Given the RFP will align with the cluster process now, will there be a maximum allowed non-compensated curtailment rate for projects specifically in the CPRE program, and if so, what would be the order in which Dominion’s existing facilities, other solar assets, and CPRE projects be curtailed?
Answer: The purpose of this CPRE stakeholder process is to develop a CPRE program framework. Any handling of curtailment would be specific to each CPRE. DESC does not have control over the number of PURPA QF solar facilities that may interconnect ahead of dispatchable CPRE resources. These PURPA QF generators may have priority and effectively increase the curtailment of CPRE resources. DESC does not have control over many of these factors and does not intend to guarantee curtailment or position in the curtailment queue. DESC anticipates increasing rates of curtailment as the flexible resources needed to avoid curtailment are delayed in other dockets or planned for implementation several years from now.
