Nova Scotia Power filed rebuttal evidence in M11689 responding to 31 intervenor recommendations on its 2024 Load Forecast Report
AI summary
- NSPI agreed with several Synapse recommendations to improve heat pump and hybrid heating modeling, EV peak impact analysis, and solar coincidence factor monitoring, while deferring scenario-based forecasting to the existing Integrated Resource Plan and 2023-2026 DSM Plan processes led by Efficiency One.
- NSPI partially rejected Synapse Recommendation 9 and 20 (scenario/sensitivity modeling for EVs, heat pumps, and DSM), arguing the existing sensitivity analysis in Section 11 and Appendix D of the Report sufficiently serves the forecast's primary planning purpose without adding undue complexity.
- On Time Varying Pricing, NSPI directed Synapse and SBA recommendations regarding peak mitigation through TOU/CPP rates to the ongoing M11822 proceeding, citing TVP Year 3 results showing ~1.1 MW of winter savings and proposed enrollment targets that make the 4 MW 2025 forecast achievable.
- NSPI rejected the Consumer Advocate's recommendation to use a 0.45 kW/vehicle EV charging peak figure, defending its 0.9 kW/vehicle (managed) and 1.6 kW/vehicle (unmanaged) estimates as better supported by Advanced Metering Infrastructure and Smart Grid Nova Scotia (M11621) pilot data, while acknowledging the nascent state of that evidence base.
- On Building Regulations and net-zero energy-ready codes, NSPI noted Nova Scotia has delayed its planned building code tier escalation, and that existing SAE model assumptions already capture incremental efficiency improvements from envelope, heating, and solar adoption trends.
