AI summary
- The Board accepted the Integrated Resource Plan 2023 Evergreen IRP Updated Action Plan and Roadmap as filed, finding the process transparent, thorough, and an improvement over the 2020 IRP, with intervenors generally supportive.
- The Board directed NS Power to undertake further study on the effective load carrying capacity (ELCC) diversity benefit of combined clean resources (wind, solar PV, battery storage, and demand response), and to complete updated battery energy storage capacity analysis before committing to 2029–2030 combustion turbine additions.
- The Board cautioned NS Power not to delay or defer any part of the Evergreen IRP process in anticipation of the new Nova Scotia Nova Scotia Independent Energy System Operator (IESO) — established under the Energy Reform 2024 Act passed April 5, 2024 — assuming IRP responsibilities, expected sometime in 2025.
- Key unresolved planning issues addressed in the proceeding include the Atlantic Loop's feasibility, hydrogen tariff development, procurement processes for 2030 decarbonization targets, and the NS-NB Reliability Tie project's urgency.
- NS Power is directed to file its next Evergreen IRP Update no later than January 31, 2025, with the 2030 targets of coal phase-out and 80% renewable sales identified as the critical planning horizon.
