NSPI files Year Four evaluation report for its Time-Varying Pricing Pilot Program, documenting load reductions across residential, commercial, and MURB customer classes through TOU and CPP tariffs.
AI summary
- The Time Varying Pricing pilot, launched in 2021, reached 8,376 participants by the end of Phase 4 (April 2024–March 2025), with residential TOU (5,616) and CPP (2,642) customers achieving statistically significant peak load reductions; retention rates remain high across all cohorts.
- Residential TOU participants achieved meaningful load reductions during both morning and evening peak hours, with overall annual bill savings of approximately $0.30/day; CPP participants saved a similar amount per day and demonstrated a daily price elasticity of response consistent with active load shifting.
- Commercial TOU and CPP results were more mixed — commercial TOU participants showed significant peak-hour load reductions but also a statistically significant increase in overall daily usage of ~15.9 kWh/day, while commercial CPP participants achieved strong load reductions during events but faced average daily bill increases during Winter.
- The newly launched Affordable Multifamily Housing And Non Profit Organizations Amf-adjacent MURB TOU pilot (10 buildings enrolled November 2024) showed statistically significant evening peak load reductions of 0.48 kW and no increase in monthly demand despite removal of the demand charge, though bill impacts were not statistically significant in Year 1.
- Nova Scotia Energy Board directives addressed in Attachment VII include analysis of demand response overlap between NS Power and Efficiency Nova Scotia (E1), coincidence of CPP events with system margin conditions, performance assessment for General Service class customers, and a review of marketing and communication practices around bill savings expectations.
