Small Business Advocate and Consumer Advocate filed submissions on Nova Scotia Power's 2024 10-Year System Outlook Report, flagging resource adequacy risks, reliability tie concerns, and gaps in long-term planning
AI summary
- The Small Business Advocate (Blackburn Law) found the System Outlook broadly consistent with the Evergreen IRP and Path to 2030 but flagged four risks: delays in resource development reducing expected wind capacity from 373 MW to 306 MW (NSPI 10-Year System Outlook, p. 21); upward-revised near-term load growth (IR-1); reliance on proposed — but not final — ECCC Clean Electricity Regulation flexibility for continued use of emitting peaking generation (IR-4(b)); and a planning reserve margin expected to fall below the 20% target in 2031–2033 (System Outlook, pp. 48–50).
- The Consumer Advocate (Pink Larkin, consulting Grid Strategies LLP) raised concern that the 'hybrid peak' scenario, though treated as the preferred approach by NSPI in multiple proceedings, is absent from the base System Outlook scenario, and requested Board direction on its development or a credible alternative.
- The Consumer Advocate identified a discrepancy between NSPI's 2024 ACE Plan (Matter M11458, Exhibit N-2) — which describes the Province's 150 MW Section 4D storage as additional to NSPI's 150 MW ECEI BESS — and NSPI's energy storage application (Matter M11539), which treats the two as a single 150 MW project, raising unresolved questions about total Energy Storage capacity through 2029.
- On the Ns Nb Reliability Intertie Project, the Consumer Advocate noted that supply-chain delays are absent from NSPI's risk register and that the planned Reliability Tie route may be subject to the same icing conditions that caused three outages on the existing L-8001 line, potentially yielding no net reliability gain during icing events; operating guidelines for a dual-outage scenario were requested.
- Both advocates referenced the anticipated transition to the Nova Scotia Independent Energy System Operator (Nsieso) and the Nova Scotia Energy Board as introducing uncertainty over future responsibility for system planning and forecasting obligations.
