AI summary
- Board Staff IR-1 asks NSPI to disclose the age of the failed transformer and its expected useful life, establishing the asset's condition relative to end-of-life benchmarks.
- IR-2 probes the cause of the phase-to-phase fault, the adequacy of existing protective systems, and whether a supplier warranty existed — key factors in any Prudency Review of the $2,418,415 expenditure.
- IR-3 requests a price comparison between the replacement transformer and a spare unit already ordered for the Bridgewater substation, flagging potential cost benchmarking concerns relevant to Capital Expenditures.
- IR-4 asks what new fault-prevention protections are being installed on the replacement transformer and why equivalent protections were not in place on the original unit, raising Asset Management and Health And Safety considerations.
- Responses from NSPI Manager of Regulatory Capital Lana Myatt are due July 22, 2026; the proceeding is partially confidential under Matter M12899.
