AI summary
- NS Power characterized overall stakeholder reception as positive, noting that Synapse "generally supports the methods underlying the technical and economic analyses," Bates White called the Update "thorough, informative, and succinct," the Consumer Advocate found it "substantial forward progress," and the Small Business Advocate agreed with NS Power's stated priorities (Reply Submission, pp. 2–4).
- On the Integrated Resource Plan Atlantic Loop, NS Power confirmed its central planning case (scenario CE1-E1-R2) excludes the Loop by 2030, while committing to pursue regional integration opportunities post-2030 per Action Plan Item 1b; it declined to share commercially sensitive Quebec negotiation details, citing risk of a "cooling effect" on negotiations (Reply Submission, pp. 4–5; Appendix A, Items 3, 5, 36).
- NS Power defended its need for approximately 300 MW of new fast-acting firm generation by 2027, arguing that unresolved ELCC diversity benefit questions for combined wind/solar/storage portfolios (raised by Synapse, EfficiencyOne, and NRR) do not eliminate the demonstrated capacity gap and should not delay procurement approvals; it committed to update the 2019 Capacity Study before the next IRP (Reply Submission, pp. 6–7; Appendix A, Items 41, 56, 57).
- Responding to Demand Side Management questions from the Consumer Advocate, NS Power clarified that the Maximum Mid DSM scenario costs $347 million more on a 26-year NPV basis than Base DSM while delivering $127 million in system savings, and acknowledged EfficiencyOne's point that the 2019 DSM Potential Study may be conservative relative to current electrification activity (Appendix A, Items 10, 21, 22).
- NS Power committed to file a detailed 2030 obligations plan with the NSUARB by December 31, 2023, as directed by the Board in M11017, and noted significant alignment between the Evergreen IRP Action Plan and Nova Scotia's 2030 Clean Power Plan released October 11, 2023 (Reply Submission, pp. 8–10).
