). The creation of the Independent Energy System Operator of Nova Scotia (IESO, IESO Nova Scotia) has implications for the continued ownership of these filing requirements, which are described herein. NS Power and IESO Nova Scotia have bee...
AI summary The document discusses the transition of responsibilities for the Load Forecast and 10-Year System Outlook (10YSO) reports between NS Power and the newly created IESO Nova Scotia. NS Power will prepare the Load Forecast report while IESO Nova Scotia will take over the 10YSO report, avoiding duplication of efforts. The 10YSO report is an annual assessment of system capacity and resource adequacy, reflecting progress toward 80% renewable energy and the phase-out of coal by 2030.

AI summary The table presents a 10-Year System Outlook (10YSO) with load forecasts, system peak, required capacity, existing and new firm resources, retirements, and reserve margin percentages for various years from 2026/2027 to 2035/2036. It outlines the capacity additions and retirements, including wind, storage, and coal-to-gas conversions, along with the resulting reserve margins.
5.3.1 Western Valley Transmission System The Western Valley transmission study was initiated to identify if load growth and new generation in the area necessitate system upgrades and/or protection scheme changes. System upgrades could incl...
AI summary The Western Valley transmission study was initiated to assess if load growth and new generation in the area require system upgrades or changes to protection schemes. Upgrades may include reactive power sources, while protection changes may involve Automatic Action Schemes (AAS) or Remedial Action Schemes (RAS). The study covers 2027 and 2032 for both normal and N-1 scenarios, with 2027 results identifying necessary upgrades.
5.4 Planned Projects The transmission plan presented in this section provides a summary of the planned reinforcement of the Nova Scotia transmission system. The proposed projects are required to maintain system reliability and security and...
AI summary This section outlines planned transmission system reinforcements in Nova Scotia to ensure reliability, security, and compliance with standards. Projects are based on system impact studies and may change due to technical studies, load forecasts, or other factors determined by IESO Nova Scotia.
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.
