AI summary The document outlines the Integrated Resource Plan (IRP) process, including objectives, evaluation criteria, key questions, and timelines. Stakeholder feedback was incorporated into the final Terms of Reference (ToR) submitted to the NSEB. Assumptions and scenarios for IRP analysis are to be developed with stakeholder consultation, covering environmental policies, demand forecasts, renewable integration, and emerging technologies.

1. IRP planning and modeling horizon The ToR states: "An IRP assesses both supply-side and demand-side resources within the context of the Nova Scotia planning environment, including all applicable Federal and Provincial environmental poli...

AI summary The ToR for the IRP emphasizes a 20-30 year planning horizon for Nova Scotia's power grid, but stakeholders recommend clarifying the base case (e.g., 25 years) and retaining flexibility for the Reliability Intertie's in-service date. The ToR's current focus on 2029-2053 is tied to the Reliability Intertie's 2028 in-service date, though delays may require adjustments.

11. Items to consider adding to the ToR There are at least three other considerations that are unmentioned in the ToR that should be considered. First, there is no mention of the role of load forecasting. Our understanding is that load for...

AI summary The text suggests three additions to the Terms of Reference (ToR): load forecasting development, fuel supply considerations for conventional and emerging resources, and grid stability studies. These are critical for the Integrated Resource Plan (IRP) to address reliability, fuel costs, and grid stability as inverter-based resources increase.

AI summary Nova Scotia Power provides feedback on the Integrated Resource Plan (IRP) and the NSEB's directives for the IESO-NS. They look forward to reviewing modelling outcomes and appreciate the additional questions related to resource needs and Mersey Hydro redevelopment. NS Power supports a planning horizon starting in 2028.

e management and transmission" (s. 9q), the roles and responsibilities for considering energy resources at the distribution-level in the 2026 IRP are currently unclear to SNS. (The final report in the Distributed Energy Resources Integrati...

AI summary The text highlights uncertainty around the 2026 IRP's treatment of distribution-level energy resources, noting NS Power deferred a DER potential assessment and SNS seeks clarity on DER integration. Dunsky's review criticized the IRP for overlooking DER value as non-wires alternatives, while referencing Ontario's evolving DER planning practices.

e we noted during the April 17th session the potential value in having an in-person session for at least one of these meetings, on reflection we do not think it is critical to convene an inperson TWG. Releasing all pre-IRP studies with ade...

AI summary Synapse supports the NS IESO's Terms of Reference for the 2026 IRP, emphasizing the need for timely release of pre-IRP studies, robust regional modeling, and demand-side management considerations. They suggest minor timeline adjustments for the ToR.
