AI summary
- Ieso Nova Scotia assumed responsibility for the 10-Year System Outlook from Nova Scotia Power, marking the first filing under the More Access To Energy Act mandate; NS Power retains the Load Forecast filing in 2026 (Exhibit N-1, p. 5).
- The 10-year resource plan (Table 3, p. 15) includes 450 MW of fast-acting generation and retirement of all coal units (Lingan 1–4, Point Aconi, Trenton 5–6, Point Tupper 2) by Winter 2029/2030, with Trenton 5 and Lingan 2 retirement deferred from 2027/2028 to maintain the 20% Integrated Resource Plan Planning Reserve Margin during the transition.
- Renewable Energy additions include 273 MW of Rate Base Procurement wind (in service by December 31, 2026), 262 MW of Green Choice Program wind (2028), a second Green Choice round targeting 350 MW (assumed COD December 31, 2029), and 1,200 MW of future wind procurements through 2036 (Table 3, p. 15).
- Energy Storage additions total 400 MW by 2029/2030 (100 MW already installed, 50 MW in 2026, 250 MW future IESO-NS BESS), complemented by 100 MW of firm imports from NB Power's RIGS project approved May 28, 2026, delivering from 2028 (p. 14).
- The Environmental Compliance forecast (Figure 3, Appendix A) shows RES at 49% in 2027 and 58% in 2028, with a razor-thin 3 GWh surplus against the 80% target in 2030; the Planning Reserve Margin falls below 20% in 2034/2035 and 2035/2036, signalling capacity gaps the 2026 IRP must address (Table 4, p. 18).
