AI summary

Nova Scotia Power filed CI# 38878 (Exhibit N-1, dated September 2, 2010) requesting approval for a $1,506,414 Capital Expenditures project to replace failing porcelain cutouts at 28 transmission substations province-wide, slightly exceeding the budget estimate of $1,500,961 primarily due to increased capitalized interest (+$6,045).
The justification is reliability-driven: porcelain cutouts develop hairline cracks from moisture ingress, causing failures that trigger System Reliability outages affecting multiple feeders and large numbers of customers simultaneously; NSPI acknowledged no formal studies underpin the program — it is driven by observed failure rates.
The 28 targeted substations (including Sackville/90H serving ~9,969 customers, Keltic Dr./11S serving ~10,152, and Willow Lane/15N serving ~9,722) span multiple divisions; however, NSPI stated it does not separately track cutout-specific outage data under Canadian Electrical Association codes, limiting granular performance reporting.
Cost breakdown per IR-T9 response: Contracts $900,000 (affiliate forces), Materials $304,000, Overhead $250,752, Interest $22,254, and Labour $30,000; the contract rate per hour was redacted from the public filing.
Work is scheduled for completion within 2010 (start October, in-service November, close December), with the majority executed by an Affiliate Transactions affiliate entity.
