Nova Scotia Power filed the Year Five (2025/26) TVP Pilot Evaluation Report, covering only the MURB TOU Tariff due to cybersecurity-related suspension of other TVP rates

M12932 · Nova Scotia Power Inc. (NSPI) - Time-Varying Pricing Pilot Program - 2024/25 (Year Four) and 2025/26 (Year Five) Evaluation Reports
AI summary
  • The Phase 5 evaluation (April 1, 2025 – March 31, 2026) is limited to the Murb Tou tariff for 10 enrolled Multi-unit Residential Building customers, as Cybersecurity disruptions forced temporary suspension of TOU and CPP tariffs for Domestic, Small General, and General rate classes (M12499).
  • AMI data gaps caused by the cyber incident constrained the evaluation: control group data was unavailable for November 2025, only 13% available in December, 51% in January, and ~97% in February and March, limiting demand and billing analyses to February–March 2026.
  • MURB TOU participants showed statistically significant load increases of 1.29 kW (5.3%) during morning peak and 0.78 kW (3.1%) during evening peak, along with significant snapback effects of 0.90 kW overall — the opposite of the intended load-shifting response, though NS Power cautions these results reflect a small sample size and constrained dataset.
  • Bill impacts were statistically insignificant, with participants experiencing an average estimated increase of $16.70/day during Winter; NS Power notes the tariff is designed to deliver savings during non-Winter periods, which could not be evaluated due to data limitations.
  • NS Power expects to resume the full TVP Pilot (all seven tariffs) for the 2026/27 Season beginning November 1, 2026, with no active new recruitment planned; stakeholder engagement sessions were held June 16 and July 14, 2026, with responses to comments filed as Appendix B.
