AI summary
- NS Power confirmed its central planning case is based on scenario CE1-E1-R2 (No Atlantic Loop, Net Zero 2035, Base Fuel Prices), selected as the lowest 26-year NPV scenario, and stated it does not anticipate Atlantic Loop availability by 2030; regional integration opportunities beyond 2030 remain under active study per Action Plan Item 1b (Items 3, 5, 15, 19, 35, 50, 53).
- Multiple stakeholders (Bates White, Consumer Advocate, Small Business Advocate) pressed for competitive all-source RFPs and robust stakeholder engagement on procurement planning; NS Power acknowledged best-practice procurement is required but characterized detailed procurement decisions as outside IRP scope, noting capital investments will be subject to NSUARB review (Items 1, 7, 47, 48).
- The Consumer Advocate and Efficiency One challenged the IRP's DSM/MMDSM cost modeling as counter-intuitive, with NS Power clarifying that across three comparable scenarios, incremental MMDSM costs exceed Base DSM by an average $347M NPV while delivering approximately $127M in system savings, and noting the 2019 DSM Potential Study remains the best available source (Items 10, 21, 22, 24, 25, 49).
- Synapse, NRR, Energy Storage Canada, and Efficiency One raised concerns that the 2019 capacity value study undervalues the ELCC diversity benefit of combined wind, solar, battery storage, and demand response; NS Power acknowledged the issue and committed to addressing it in future IRP iterations, but argued Board approval of new firm capacity should not be contingent on further modelling refinement (Items 41, 56, 60, 61, 62).
- Stakeholders including the Consumer Advocate, Eastward Energy, and PHP supported a third-party-led multi-stakeholder study of the hybrid peak mitigation scenario; NS Power endorsed the concept but requested it be led by an impartial third party, and confirmed the NS-NB Reliability Tie is targeting a 2028 in-service date (Items 4, 8, 13, 20, 29, 45, 54).
