Nova Scotia Power filed its 2023 Evergreen IRP Action Plan and Roadmap update, outlining a near-term resource development path to meet 2030 decarbonization targets across wind, storage, fast-acting generation, and demand response.
AI summary
- The 2023 Evergreen IRP, modeled across 24 scenarios, finds that approximately 1,500 MW of new wind capacity (beyond the existing 600 MW) and 200 MW of solar are required by 2030 to meet coal phase-out and 80% renewable electricity targets (p. 5–6).
- All modeled scenarios select the Ns Nb Reliability Intertie Project (a second 345 kV AC line between Onslow NS and Salisbury NB) and at least 100 MW of 4-hour Energy Storage battery capacity by 2030, with storage additions beginning as early as 2025 (p. 7).
- New fast-acting generation (combustion turbines) of approximately 300 MW by 2027 and an additional 300–600 MW by 2030 is identified in all scenarios to balance variable renewable output and maintain planning reserve margins; Small Modular Reactors (Nuclear Power) appear only in No Atlantic Loop scenarios at the end of the 2048 planning horizon (p. 6–7, 15).
- The Action Plan includes updated Demand Side Management avoided costs in collaboration with the DSMAG, expansion of demand response pilot programming to 75 MW nameplate capacity by 2025, and further assessment of a hybrid peak electrification scenario that showed cost savings relative to base load scenarios (p. 16–17).
- Roadmap monitoring items cover Federal Clean Electricity Regulations, offshore wind, hydrogen tariff impacts, wind integration studies, and an annual evergreen IRP refresh process with stakeholder comment opportunities (p. 18–19).
