AI summary This section discusses the results of an ELCC study conducted on behalf of NS Power and IESO Nova Scotia, which updated ELCC factors for wind, solar, energy storage, and demand response. The study accounted for saturation effects and identified diversity benefits from combining different resources, contributing to firm capacity and resource adequacy.

3.2.4 Fast-Acting Generation IESO Nova Scotia has initiated a procurement process for 300 to 600 MW of fast-acting generation capacity for the province. The draft Request for Proposals (RFP) and Tolling Agreement was made available for pro...

AI summary IESO Nova Scotia has initiated a procurement process for 300 to 600 MW of fast-acting generation to support the province's clean energy transition. This capacity is critical for maintaining supply reliability as renewable energy penetration increases and peak demand grows. The 2026 10-Year Outlook Resource Plan includes 450 MW of fast-acting generation, with additional needs identified by 2035/2036.

Thermal Retirement Schedule The thermal retirement schedule complies with the 2030 coal phase-out targets. Previous 10-year load and resource outlooks presented retirements of Trenton 5 and Lingan 2 in Winter 2027/2028. Based on the curren...

AI summary The thermal retirement schedule aligns with the 2030 coal phase-out targets. Previous retirements of Trenton 5 and Lingan 2 were planned for Winter 2027/2028, but IESO Nova Scotia now expects these units to remain in service until Winter 2029/2030 to maintain adequate Planning Reserve Margin (PRM) until new fast-acting generation is operational.

6 CONCLUSION This report constitutes IESO Nova Scotia's 10-Year System Outlook for the 2026-2036 horizon and satisfies the requirement under Section 3.3.1.3 of the Nova Scotia Wholesale and Renewable to Retail Electricity Market Rules . Th...

AI summary IESO Nova Scotia's 10-Year System Outlook (2026-2036) outlines the province's transition to 80% renewable energy and coal phase-out by 2030. The report highlights the need for successful implementation of projects to maintain system adequacy and meet decarbonization targets, while studying impacts of load and generation, including inverter-based resources, to ensure system reliability.

- Net System Requirement. - a) Please explain the drivers between the increase in Renewable-to-Retail (RtR) Energy from 15 GWh in 2026 to 239 GWh in 2027 and then 286 GWh in 2028, respectively. - b) Please explain why RtR sales are assumed...

AI summary The text requests an explanation for the increase in Renewable-to-Retail (RtR) energy from 2026 to 2028, the assumption of flat RtR sales from 2028 to 2036, and a reconciliation of discrepancies between energy production increases and resource expansion figures in Table 3.

Request IR – 16 - Refer to the 2026 Report Section 4.3 Clean Electricity Regulations (CER), page 21. - Specifically considering the treatment of new fast-acting generation under the CER: - a) Please describe IESO NS's current assessment of...

AI summary The text requests the IESO NS to assess whether 450 MW of new fast-acting generation qualifies as a 'Planned Resource' under the Clean Electricity Regulations (CER), provide updated analysis on emissions performance standards, and describe implications for resource plans if the generation is not eligible as a Planned Resource.

- 8: Large-Load SIS. - a) For each of the nine projects listed in Table 8, please provide the expected in-service date, ramp schedule for load growth, load factor, and any interruptible or curtailment provisions. - b) Are these loads inclu...

AI summary The response to the SBA's information requests regarding nine large-load projects discusses in-service dates, ramp schedules, load factors, and interruptible provisions. It notes that ramp rates are not yet determined and that load factors are not considered during the System Impact Study. The response directs further questions to another document.

Request IR – 22 - The 2025 Report included several sections that do not appear in the 2026 Report, including but - not limited to various sections under "Generation Resources", "Resource Adequacy", - "Transmission Planning", "Transmission...

AI summary The 2025 Report contains sections not present in the 2026 Report, including 'Generation Resources', 'Resource Adequacy', 'Transmission Planning', 'Transmission Development', and 'Clean Energy Regulations'. The request asks for an explanation of their omission and where equivalent information can be found, including whether NS Power or IESO NS now handles these topics.

Request IR-11 Refer to the 2026 Report Section 3.2.3 – NS Community Solar, page 13, which states that "The forecast commercial operation date for the first three projects approved by the Nova Scotia Department of Energy is Q3 2027." - a. P...

AI summary The document requests information about the development status and potential risks of three Community Solar projects, as well as a reconciliation of additions and retirements in two resource plans. It emphasizes the importance of meeting commercial operation dates and understanding differences in resource planning.

Request IR-19 Refer to the 2026 Report 5.2.2 Large Load Interconnection Requests, page 23, referring to Table 8: Large-Load SIS. - a. For each of the nine projects listed in Table 8, please provide the expected in-service date, ramp schedu...

AI summary Request IR-19 asks for details on nine large-load interconnection projects, including their expected in-service dates, load factors, and impact on resource adequacy. It also inquires if these loads are included in the load forecast and the implications for capacity requirements.

2. Resource Adequacy Risks and Contingency Planning The System Outlook forecasts a reserve margin surplus in every year through Winter 2033/2034. 8 However, that surplus depends on many projects being completed on schedule. A significant n...

AI summary The System Outlook forecasts a reserve margin surplus through Winter 2033/2034, but this depends on timely project completion. The SBA argues that the surplus may not be sufficient if multiple projects are delayed, and criticizes the lack of contingency planning by IESO Nova Scotia. NSPI also questions the contingency planning approach.

Submissions Consequently, the SBA respectfully submits that the Board should consider requiring IESO to do the following: - 1. Coordinate with NSPI and other parties to obtain information relevant to system planning, rather than deferring...

AI summary The SBA submits that the IESO should improve coordination with NSPI, develop contingency plans, clarify load forecast criteria, reconsider battery degradation assumptions, and address environmental compliance risks. The submission highlights the need for the Board to ensure transparency and proper division of responsibilities between NSPI and IESO during the transition.
