NSUARB Board Staff issued 26 Information Requests to Nova Scotia Power on its 2024 Load Forecast Report, probing methodology changes, economic assumptions, and electrification forecasts
AI summary
- Board Staff questioned year-over-year changes in Forecasting Methodology across multiple forecast components, including revised population projections (IR-5, IR-18), updated economic driver data (IR-7, IR-8), changed end-use intensity figures (IR-15), and discrepancies in the February 4, 2023 system peak event data between the 2023 and 2024 reports (IR-25).
- Several IRs probe Heat Pumps and Strategic Electrification assumptions, including the basis for a 100% heat pump saturation rate by 2050 (IR-10), heat pump intensity adjustments attributed to the 2023 Polar Vortex (IR-11), water heater saturation actuals versus forecast (IR-12), and the 70/30 managed-to-unmanaged EV charging ratio (IR-13).
- Board Staff challenged the continued use of potentially outdated inputs, including a structural building efficiency index based on 2013 data (IR-19), economic model inputs described as "a decade out of date" (IR-21), and a COVID adjustment variable despite positive Nova Scotia GDP growth since 2021 (IR-21).
- IR-17 questioned NS Power's application of a uniform price elasticity of -0.15 across all rate classes, citing NS Power's own Appendix C evidence from matter M11683 showing class-differentiated short- and long-run elasticities as a more robust approach.
- IR-26 raised the scope of the hydrogen sensitivity analysis in Appendix D, asking why only two hydrogen facilities are anticipated by 2034 and requesting a phased load demand table as those facilities ramp operations.
