3.2 Changes in Capacity The basis for the 2026 10-Year System Outlook resource plan is the Government of Nova Scotia's 2030 Clean Power Plan and NS Power's Evergreen IRP scenario CE1-E1-R2 (net zero 2035, current policy and trends electrif...
AI summary The 2026 10-Year System Outlook resource plan is based on the Government of Nova Scotia's 2030 Clean Power Plan and NS Power's Evergreen IRP scenario. It anticipates a net increase in installed capacity of 2,804 MW and firm capacity of 370 MW over the next 10 years, supporting decarbonization goals and 80% renewable energy electricity sales by 2030.
Response IR - 1 - a,b) The expansion and acceleration of IESO Nova Scotia's second procurement process is aligned with the resource plan identified in the 2026 10 Year System Outlook. - c) The commissioning of 150 MW of BESS capacity in 20...
AI summary IESO Nova Scotia's second procurement process is aligned with the 2026 10 Year System Outlook and the Clean Power Plan. The commissioning of 150 MW of BESS capacity in 2025 and 2026 partially meets the 300-400 MW energy storage target. The procurement process will refine the optimal capacity, timing, and technology for future resources.
Request IR – 5 - Pdf page 13 of the report states that the fast-acting generation requirement changed from 600 - MW to 450 MW compared to the last NS Power Integrated Resource Plan (IRP). Please explain - what changes in conditions resulte...
AI summary The fast-acting generation requirement was reduced from 600 MW to 450 MW due to an agreement with NB Power for a 100 MW firm import from their RIGS project. This change was influenced by the 2023 Evergreen IRP and will be further refined in the 2026 IRP.
Request IR-6: - If the new 450 MW of fast-acting combustion turbines generating capacity is not in service by - 2030, please describe IESO Nova Scotia's specific plan to meet projected system load, as well - as maintain system reliability...
AI summary The document requests IESO Nova Scotia to outline a specific plan to meet projected system load and maintain reliability if the new 450 MW of fast-acting combustion turbines are not operational by 2030. It also asks how this plan will align with NS Power's requirements to phase out coal and achieve 80% renewables by 2030.
Request IR-04 Refer to the 2026 Report Section 3 – Existing Generation Resources, pages 7-8. - a. Please provide a comparison table showing the ELCC values from the 2025 Report and the 2026 Report. Provide the average and incremental ELCC...
AI summary The document requests clarification and additional information regarding the 2026 Report's use of Effective Load-Carrying Capacity (ELCC) values, specifically comparing data from the 2025 and 2026 reports, the basis of ELCC assumptions, and the reconciliation of ELCC values for wind resources at different penetration levels.
Request IR-8: - Reference : Exh. N-1, Table 9, and Matter M12592 regarding the ECC Dynamic Line Rating (DLR) project with a cost of $7 million, including $5.2 million in NRCan funding. - a) Please explain why this project is not included i...
AI summary Request IR-8 seeks clarification on the exclusion of the ECC Dynamic Line Rating (DLR) project from Table 9, the significance of the project, and its implications on transmission line interruptions, risk mitigation, and potential benefits such as congestion relief and cost savings. It also requests data analysis, evaluation plans, and comparisons with Ambient Adjusted Rating (AAR) solutions.
