AI summary
  • The Nova Scotia Energy Board (NSEB) issued its decision letter dated September 1, 2026, formally approving Nova Scotia Power Inc.'s (NS Power) Unforeseen and Unbudgeted (U&U) capital expenditure of $2,418,415 for replacement of the 67C-T64 Transformer at the Whycocomagh Substation (CI C0082085).
  • The Board found the costs "justified and reasonable," accepting that the transformer failed due to an internal phase-to-phase fault caused by insulation degradation after more than 40 years of service — below the estimated 50-year useful life — and that the damage was non-repairable, requiring immediate action.
  • NS Power's extended final cost date of December 2026 (beyond the normal six-month window) was attributed to a Cybersecurity event that rendered computer systems unavailable during project completion in October 2025, delaying expenditure validation and reconciliation.
  • The Board explicitly cautioned NS Power that, now recovered from the cyber event, it is expected "to return to filing applications on time to avoid delay in their approval" — signalling regulatory patience has limits on timing deviations.
  • The approval sheet (signed by COO Dave Pickles on June 11, 2026 and countersigned by the Board on September 1, 2026) confirms a $0 budget amount against a $2,418,415 project estimate, consistent with the unbudgeted nature of the filing.
