OBJECTIVES The objectives of IESO Nova Scotia's first IRP are: - Develop a robust long-term electricity system plan that is reliable, sustainable, and cost-effective covering the next 20 to 30 years; - Evaluate the range of energy resource...
AI summary The objectives of IESO Nova Scotia's first Integrated Resource Plan (IRP) include developing a long-term, reliable, and cost-effective electricity system, evaluating energy resources (including non-electric options), identifying procurement needs, supporting sustainability goals, and calculating avoided costs for demand-side management.
KEY QUESTIONS In the NSEB's order for IESO Nova Scotia's Approval of its Proposed Expenditure and Revenue Requirement for the Test Year Ending March 31, 2026 (M12412), the following direction was provided for this IRP: "IESO Nova Scotia is...
AI summary The Nova Scotia Energy Board (NSEB) directed IESO Nova Scotia to address specific issues in its Integrated Resource Plan (IRP), including cost analysis for new supply-side resources, regional system modeling, ELCC portfolio updates, demand response scenarios, and emissions linkage. Additional key questions focus on decarbonization targets, offshore wind opportunities, and Mersey Hydro redevelopment.

APRIL 17 STAKEHOLDER SESSION QUESTIONS Question/Comment Response Where does health and health equity get factored into IRP? What would it take to have scenarios that consider impact on Nova Scotians' Health? Health and health equity are in...
AI summary The stakeholder session question asks how health and health equity are factored into the Integrated Resource Plan (IRP). The response indicates that health and health equity are indirectly addressed through federal and provincial environmental policies and regulations that reduce emissions from electricity generation.
INDUSTRIAL GROUP Question/Comment Response Cost evaluation should also incorporate risk, not just nominal cost. Fuel-based generation carries fuel price risk, while wind and solar carry resource variability risk. These risks should be expl...
AI summary The Industrial Group emphasizes the need to incorporate risk assessment in cost evaluations, noting that fuel-based generation and renewables carry different risks. They also argue that environmental evaluation should consider factors beyond GHG reduction, such as water use and land degradation. The response highlights that risk is evaluated through alternative scenarios and that environmental policies go beyond GHG considerations.
Key Questions We support and are glad to see the NS IESO's stated intentions to confirm the resource needs of the system to achieve Nova Scotia's decarbonization targets and to determine the economic opportunity for domestic use of energy...
AI summary The text supports the NS IESO's efforts to identify resource needs for achieving Nova Scotia's decarbonization targets and assess the economic potential of offshore wind energy.
• Process - o Operating Costs : NRStor is encouraged by IESO-NS's proposal in the draft ToR to include operating and maintenance costs in addition to capital costs when evaluating existing and candidate resources, as directed by M12412. -...
AI summary NRStor recommends including operating costs in resource evaluations, advocating for technology-neutral grid service criteria, enhanced stakeholder transparency, targeted outreach to energy storage developers, and adopting a Societal Cost Test (SCT) to align with provincial climate goals. These proposals aim to improve the Integrated Resource Plan (IRP) process and ensure alignment with the Clean Power Plan and More Access to Energy Act.
Nova Scotia Power TOR Section Details/Component NS Power Feedback/ Questions Assessment Period Proposed Study Period of 2029 - 2053 NS Power is supportive of a 25-year assessment period that captures a pre-2030 and post-2050 time period. H...
AI summary Nova Scotia Power supports a 25-year Integrated Resource Plan (IRP) assessment period starting in 2028, covering 2028–2052, to align with the Clean Power Plan (CPP) work and other initiatives aimed at meeting 2030 targets, including biomass conversion and wind energy additions.
Emissions As noted above, this first IRP presents an important opportunity for the IESO to demonstrate a clear and credible commitment to climate change mitigation and emissions reduction. While it is encouraging to see GHG Reduction inclu...
AI summary The text criticizes the proposed 10% weighting for GHG reduction in the IRP, arguing it is insufficient and risks being meaningless. It recommends increasing the weighting to 50% and clarifying prorating methodology. Full marks should be awarded to zero-emission sources, while non-compliant sources receive zero marks to align with 2050 climate goals.
appreciate further clarity on how energy resources at the distribution-level will be considered in the 2026 IRP, and how that will interact with other processes (e.g., DERIR, NSPI Load Forecast etc). 4. The Clean Power Plan states that "…[...
AI summary The text requests clarity on integrating distribution-level resources into the 2026 IRP and their interaction with processes like DERIR. It advocates for the IRP Score Card to differentiate costs of imported fuels versus clean local electricity, aligning with the Clean Power Plan's goal of electrification to reduce bills and replace imported fuels.
