Nova Scotia Power filed responses to six NSEB information requests on the $1.38M Point Aconi boiler refractory refurbishment capital project, disclosing inspection findings, asset management methodology, and a maintenance-to-retirement strategy.
AI summary
- NS Power confirmed that CI C0067908 is one of a series of annual refractory projects (2022–2027) targeting the Point Aconi Generating Station CFB boiler, with each year's scope driven by condition-based inspection findings rather than a fixed replacement cycle (IR-1 Response).
- NS Power disclosed it cannot provide full cost breakdowns for prior refractory projects due to a Cybersecurity incident that impaired access to historical financial records; the 2026 project scope also remains undefined pending post-2025-outage inspection data (IR-1(b) Response).
- A Fall 2024 third-party inspection report (Attachment 1 to IR-2) documented specific degradation—including thin combustion chamber walls, damaged return legs, and scroll floor wear—and formed the technical basis for the 2025 project scope, with a 3–5 year typical Asset Management service life for refurbished refractory components.
- NS Power provided its Asset Strategy Committee Process (NSPI-AMS-001, effective June 9, 2025) as Attachment 1 to IR-3, describing a 5×5 risk matrix combining condition (probability of failure) and criticality (consequence) to score assets 1–25, with scores ≥15 triggering mandatory Capital Expenditures mitigation.
- In response to IR-6, NS Power confirmed Point Aconi is planned for retirement in 2029/2030 in alignment with the 80% renewables target, but stated annual outage-based refractory inspections will continue to retirement to prevent unplanned outages, with no full refractory replacements planned before decommissioning.
