AI summary
- Nova Scotia Power Incorporated submitted CI C0080108 on April 9, 2026, requesting subsequent approval for Phase 1 replacements and upgrades on L-5532, a 95.9 km, 1,128-structure 69 kV Transmission Planning line built in 1955 that serves eight substations and approximately 2,915 customers.
- The $3,455,473 project estimate exceeds the 2026 2025 Ace Plan budgeted amount of $2,490,532 by $964,941, with the variance attributed to additional scope identified through engineering analysis of LiDAR inspection data after the ACE Plan submission.
- Work scope covers 75 structures, including 72 full structure replacements and 3 deteriorated asset replacements (wood poles, crossarms, anchors, guying components, insulators, and associated hardware), with contracts for wood poles ($872,345) and overhead conductor ($1,191,739) comprising the largest cost components.
- The project is classified as a Class 3 estimate with a 15% contingency ($406,120), reflecting identified risks including outage window constraints, unforeseen material or contract cost increases, and access challenges in wet or remote locations.
- Reliability concerns are cited as the primary driver: two affected feeders (91W-411 and 57W-402) are identified as CKAIDI problem feeders under NS Power's Performance Standards, with 91W-411 flagging as a problem feeder for the second consecutive year; Phase 2 (CI TBD, 2028) is noted as a planned follow-on.
