Nova Scotia Power filed responses to NSEB Information Requests 1–6 regarding the March 17, 2026 storm outage analysis report
AI summary
- Nova Scotia Power clarified that all outages beginning within the province-wide storm window ("Storm Start" to "Storm End") are included in event totals, including those coded as planned outages, consistent with prior storm reports M11016 and M11516 (IR-1, IR-2).
- The March 17, 2026 storm interrupted 82,355 customers (65,545 unique) for 274,172 customer hours over 18.9 hours, with geographic concentration in Halifax and Cape Breton East; all customers restored within 48 hours (IR-4, Table 1).
- Restoration was notably slower than Tropical Storm Elsa (July 2021): only 8.85% of customers restored within 6 hours vs. 20.06% for Elsa, and 46.76% within 12 hours vs. 83.96% for Elsa, despite comparable peak winds (85 vs. 81 km/h) (IR-4, Table 2).
- Tree-related outage data for 21 feeders was provided; Halifax feeder 23H-304 recorded the highest customer hours of interruption (28,229 CHI from 2 events and 3,597 customer interruptions); NS Power confirmed vegetation management is risk-based rather than cycle-based (IR-3).
- NS Power disclosed it does not track Level 1 and 2 storm restoration costs (labour, contracts, materials, travel) at the breakdown requested in IR-5, and this data is therefore unavailable for this event.
