AI summary
- Nova Scotia Power Inc confirmed Lingan Unit 2 (LIN2) has a rated capacity of 148 MW and was recalled to service multiple times between Q2 2025 and August 2026, generating a cumulative total of approximately 239,495 MWh across eight dispatch intervals (IR-1(c) table).
- The 2026/2027 winter planning reserve margin stands at 22% of firm peak with LIN2 available, just above the NPCC reliability criterion of 20%; NSPI stated that without LIN2's capacity contribution, the system would not meet the required System Reliability threshold (IR-2).
- Firm import constraints limit near-term alternatives: Newfoundland provides ~145.4 MW firm via the Maritime Link Base Block, but no additional dispatchable resources exist there; New Brunswick's 100 MW firm capacity is not expected until as early as 2028, contingent on the NS-NB reliability intertie and NB Power RIGS project being commissioned (IR-3).
- The $4,392,251 approval request covers capital expenditures only; a separate $1,331,000 in 2025 OM&G costs — expensed as non-regulated — is also submitted for reclassification to regulated operating expenditures consistent with the Board's prior decision in M11706 (IR-5).
- NSPI disclosed cumulative capital investments of approximately $5.48M across three prior LIN2 capacity requirement CIs (2022/23 through 2024/25) and confirmed that future 2026/27 and 2027/28 project amounts remain TBD, dependent on as-found inspection results during annual maintenance outages; the 2026/27 amount is expected to be similar to the current $4.39M project (IR-6, IR-7).
