Four intervenors filed 53 combined Information Requests to Nova Scotia Power on its 2026 Load Forecast, pressing hardest on hybrid heating assumptions, EV and solar forecasting, and the exclusion of trade tariff impacts.
AI summary
- Synapse Energy Economics (Board Counsel Consultant) filed IRs 1–21 (Exhibit 102381), covering forecast accuracy for system peak demand (IR-2, referencing Board Decision M12349 Table 1), lagged temperature variables, bottom-up peak disaggregation methodology, omission of trade tariff impacts (IR-5), battery/V2G exclusions (IR-6), heat pump load modelling (IR-7), residential and commercial hybrid heating workpapers (IR-8, IR-9), EV mandate changes including cancellation of the EV Availability Standard (IR-11), solar coincidence factors (IR-13), DSM historical savings inputs from Efficiencyone (IR-15), and the anticipated ELCC study timeline (IR-21).
- Efficiencyone filed IRs 1–11 (Exhibit 102386), focusing almost entirely on the residential hybrid heating model embedded in NS Power's 2026 SAE regression: E1's calculations in IR-02 Table 1 show that the modelled program implies an average of 1,656 full-load hours of non-electric backup heating use per participant per year and ~3,034 kWh of annual energy reduction per participant, and E1 questions whether these figures are consistent with the program's intended design; E1 also asks whether hybrid heating constitutes a Demand Side Management activity under ss. 79A–79L of the Public Utilities Act Nova Scotia (IR-01(f)).
- The Consumer Advocate filed IRs 1–6 (Exhibit 102388), challenging the assumption that enrolled hybrid heating customers would use non-electric backup for ~1,729 hours/year (IR-1(f)(ii)), requesting a TVP/DLC/BNI curtailment forecast-versus-actual tracking table (IR-3), asking when NS Power will fulfil its AMI commitment to reduce system peak by 26 MW (IR-3(d)), and probing the treatment of Renewable To Retail energy in system planning (IR-6).
- The Small Business Advocate (IRs 1–8, Exhibit 102392) and Solar Nova Scotia (IRs 1–7, Exhibit 102393) raised additional methodological questions: SBA focused on AMI data sufficiency (IR-1), 2025 data reconstruction due to the NS Power cyber incident (IR-2), housing-completion adjustments to the Signal49 forecast (IR-3), and peak-model temperature lag weightings (IR-7); Solar NS questioned the near-zero industrial electrification trajectory against net-zero-by-2050 obligations under the Environmental Goals And Climate Change Reduction Act (IR-1), the 0 MW peak credit assigned to solar because the system peak occurs after sunset (IR-6), and the omission of the federal Clean Technology Investment Tax Credit from the commercial heat pump forecast despite its application to the solar forecast (IR-7).
- All responses are due July 7, 2026; the requests collectively signal that intervenors will scrutinize (a) the 50% hybrid heating participation assumption against the absence of any approved program, (b) methodological consistency in how new-technology loads are modelled versus excluded, and (c) whether the 2026 forecast adequately reflects post-filing federal policy announcements (retrofit relaunch announced May 14, 2026, one day before filing).
