Consumer Advocate and Synapse file critical intervenor evidence challenging NS Power's heat pump intensity, hybrid heating, and demand reduction forecasts in M12861 2026 Load Forecast proceeding
AI summary
- Consumer Advocate witness John D. Wilson (Grid Strategies) recommends the Board immediately reject NS Power's residential hybrid heating forecast of 48 MW peak mitigation and 83 GWh energy reduction as unsupported, citing an inconsistent and undocumented heating intensity methodology that has swung wildly across load forecast vintages (e.g., 2030 heat pump heating intensity ranging from 2,005 to 3,188 kWh/house across the 2022–2025 reports) (Exhibit N-8, Sections III–IV).
- Wilson finds NS Power's demand reduction forecasts for BNI Demand Response BNI Curtailment, Residential Demand Response Program DLC, and Time Varying Pricing TVP are unreasonable, recommending DLC be cut to 4 MW and TVP growth capped at 0.5 MW/year beginning in 2027, while BNI curtailment should be raised to 26 MW in 2032 to reflect consistent under-forecasting (Exhibit N-8, Section V, Tables 4–6).
- Synapse (Exhibit N-9) supports the 2026 Forecasting Methodology forecast's higher net system requirement — growing at 0.4% CAGR in energy and 1.1% in peak to 2,765 MW by 2036 — driven by EVs, electric heating, and new customers, but critiques the EV forecast as inappropriately top-down from a cancelled federal standard rather than a bottom-up realistic projection.
- Synapse raises concerns about hybrid heating participation assumptions: NS Power models 50% of new NAE heat pump systems enrolling in a hybrid curtailment program from launch in 2028 without a ramp, while E1's residential smart thermostat program achieved only 0.3% first-year participation; Synapse recommends a gradual ramp and expanded eligibility to existing NAE stock at lower rates (Exhibit N-9, Section 5.1).
- The Small Business Advocate's submission questions NS Power's adjustment to Signal49's housing completions forecast — replacing a steep projected decline with a flat 10% annual decline — arguing it is not a well-supported central forecast and requesting a lower-housing sensitivity case in future reports (Exhibit 102867).
