AI summary
- Board Staff IR-1 (Doc. 323177, p. 1) requests confirmation that the six annual refractory projects (2022–2027, totalling known costs of approximately $2.77M across three completed years) are discrete scopes, and asks Nova Scotia Power Incorporated to provide cost breakdowns, project scopes, and the criteria used to segment and prioritize each annual tranche of work on the same boiler asset.
- IR-2 (p. 2) seeks clarification on whether any work has yet been performed on the seven identified refractory zones (cyclones, crossover ducts, loop seal cans, return legs, and lower combustor), and if not, requests the methodology and assumptions behind the budget estimate along with supporting technical studies.
- IR-3 (p. 2–3) asks for a full explanation of Asset Management methodology and risk-rating system used to prioritize refractory components, as well as a comprehensive description of all major Point Aconi (POA) equipment categories, their service lives, and current ages.
- IR-4 (p. 3) questions whether CI C0067908 (refractory replacement, M12373) and the concurrently filed CI C0067906 (boiler refurbishment, M12372) are planned to proceed simultaneously, and why refractory work has been separated from broader boiler refurbishment projects.
- IR-6 (p. 3–4) directly links the application to Integrated Resource Plan planning, asking how a refurbishment investment at Point Aconi — slated for retirement by 2029/2030 per the 2025 10-Year System Outlook (M12386, p. 17) — aligns with the 80% renewable energy target, and whether Nova Scotia Power Incorporated intends to revise its maintenance strategy as retirement approaches.
