AI summary

Board Staff (IR-1) pressed Nova Scotia Power Incorporated to explain what changed between August 2025 — when NSP forecast D055 spending would stay within budget — and year-end, resulting in a 107% overage of approximately $11.5M above the approved 2025 Ace Plan budget for Routine D055.
IR-2 requests a cost breakdown by category (labour, materials, contractor services, overhead) for 2025, as well as a year-by-year historical spend and volume breakdown from 2019–2025 across Bin Work, Field Driven Work, and Street Light and Service Removals.
IRs 4 and 5 probe the two primary cost drivers identified in the application: $10.2M attributed to advancement of higher-priority condition-driven Bin Work (including Glace Bay area feeder projects), and $1.7M tied to increased deficiencies identified through regional operations and engineering.
IR-6 requests detailed Excel-format project lists including estimated costs, feeder numbers, customer counts, risk assessments, and locations, alongside feeder-level reliability metrics (SAIFI, SAIDI, outage causes, customer interruptions) from 2021 onward, excluding Major Events and Loss of Supply.
IRs 3, 7, 8, 9, and 10 examine broader Asset Management practices, including forecasting methodology adequacy, asset prioritization and selection criteria, premature replacement, system hardening and resilience considerations, and integration of cost-effective technological solutions.
