Board Staff, Consumer Advocate, and Small Business Advocate file 35 combined Information Requests to Nova Scotia Power on the Time-Varying Pricing Pilot Year Four (2024/25) and Year Five (2025/26) Evaluation Reports, with responses due September 14, 2026
AI summary
- NSEB Board Staff issued IRs 1–10 (Exhibit 103362) covering CPP event scheduling gaps, control group matching for de-electrified participants, rate-class switching, off-peak energy savings, heating scenario mix, commercial enrollment discrepancies, demand charge modeling, and MURB load analysis across Year 4 and Year 5 reports
- Consumer Advocate filed IRs 1–19 (Exhibit 103366) probing commercially significant findings including statistically significant TOU bill increases of 12.3 $/day in Winter (Appendix A, p. 73), absence of aggregate MW or dollar quantification of peak reduction, recalculation status of avoided-cost benefits using the August 2024 Demand Side Management Avoided Cost series, Rate Design Scorecard completion, and Customer Information System upgrade timelines for time-differentiated demand charges
- Small Business Advocate filed IRs 1–6 (Exhibit 103367) focused on commercial class performance disparities — notably that General rate class achieved 9.7 kW CPP load reduction while Small General showed statistically insignificant response — and questioned whether the shift to a Linear Mixed Effects model explains why statistically significant commercial results appear for the first time in Year 4
- Across all three sets of IRs, intervenors pressed Rate Design concerns including the 6% load-shift ceiling imposed by non-coincident demand charges, NS Power's stated inability of current systems to support peak/off-peak demand differentiation, and whether the demand charge — or the pricing signal ratio — is the binding constraint on deeper load shifting
- The Consumer Advocate highlighted that only 209 of approximately 2,500 Eco Shift enrollees are also TVP participants, and asked whether NS Power will incentivize or require enabling technology (smart thermostats, water heating controls) as a condition of or inducement for TVP enrolment, given the measured +0.40–0.46 kW load-reduction enhancement from technology co-enrolment
