lts, IESO Nova Scotia will identify a preferred resource plan, and develop an action plan for post-IRP activities, including identifying target capacity and timing for near-term resource procurements. Report : IESO Nova Scotia will publish...

AI summary IESO Nova Scotia will develop an action plan for post-IRP activities, publish a public report on the IRP process, update avoided costs with Efficiency One and the DSMAG, and engage stakeholders using an 'open to all' strategy. Future IRP cadence will be defined, potentially transitioning to a fixed schedule as recommended in the Dunsky report.

APPENDIX A – IRP SCORECARD Least Cost (80%) – Measured as the cumulative total 25-year Net Present Value (NPV) of the modelled capacity expansion and production costs plus end effects. The resource plan with the lowest total NPV, including...

AI summary The document outlines the scoring criteria for the Integrated Resource Plan (IRP), evaluating four key areas: Least Cost (based on NPV), GHG Reduction (emissions), Technology Risk (reliance on emerging tech), and Economic Growth (job creation). Each criterion is scored proportionally to its weight (80%, 10%, 5%, 5%).

APPENDIX A – DRAFT IRP SCORECARD Least Cost (8070%) – Measured as the cumulative total 25-year Net Present Value (NPV) of the modelled capacity expansion and production costs plus end effects. The resource plan with the lowest total NPV, i...

AI summary The draft IRP scorecard evaluates resource plans using four criteria: Least Cost (NPV of costs), GHG Reduction (emissions), Technology Risk (reliance on unproven tech like SMRs), and Economic Growth (job creation). Scores are normalized against optimal benchmarks for each category.

the first technical working group meeting on May 13th guidelines were established and agreed to that allow members to designate an alternate representative in order to allow for continuity of support throughout the process. The ToR propose...

AI summary The Technical Working Group established guidelines for alternate representatives to ensure continuity. The TOR proposed a 70% cost and 30% non-cost weighting for resource portfolios, but stakeholders recommended increasing the cost weighting. In response, IESO Nova Scotia adjusted the scorecard, increasing cost to 80% and reducing economic growth and technology risk to 5% each.

EAST COAST ENVIRONMENTAL LAW these categories or, at minimum, consider reductions to their weights in the evaluation process. Eastward suggests that moving to 30% of the evaluation on factors other than Least Cost when electricity customer...

AI summary Eastward argues that increasing the evaluation weight of factors other than Least Cost in the Integrated Resource Plan (IRP) is inappropriate when affordability is a concern, suggesting a maximum of 15% for such factors. In response, IESO Nova Scotia has increased the cost weighting to 80% and reduced the weights for economic growth and technology risk. Eastward also questions how job creation data will be sourced for the Economic Growth criteria.

INDUSTRIAL GROUP Question/Comment Response The IG recommends that the TOR and final IRP explicitly state that the least cost NPV outcome will govern selection of the preferred resource plan, accounting for reliability and compliance constr...

AI summary The Industrial Group recommends that the TOR and final IRP prioritize the least cost NPV outcome in selecting the preferred resource plan, emphasizing affordability and customer impact. IESO Nova Scotia has adjusted the scorecard weightings, increasing cost to 80% and reducing economic growth and technology risk to 5% each. Dunsky's recommendations also suggest a detailed presentation of the preferred plan in the IRP.

10. Evaluation criteria The ToR proposes to plan future resource portfolios based on cost (70%) and other non-cost factors (30%).[20](#page-59-0) We recommend the IESO reconsider this weighting to more heavily weigh cost, particularly wher...

AI summary The ToR proposes a 70% cost and 30% non-cost weighting for resource portfolio planning. The IESO is advised to prioritize cost further, noting that GHG reduction can be addressed via OBPS carbon intensity allowances, while technology risk and economic growth metrics face implementation challenges. Non-cost criteria weights should be reconsidered.

Industrial Group To the IRP Team – On behalf of the iG, we have reviewed the comments previously filed and offer one additional consideration not yet addressed: First, we share the concern of BW regarding weighting of non-least cost factor...

AI summary The Industrial Group (IG) supports using long-term NPV as the primary determinant for the preferred resource plan in Nova Scotia's Integrated Resource Plan (IRP). It criticizes the proposed 10% weighting of the economic growth metric for overstating job creation benefits while ignoring electricity cost impacts on industries and export sectors. The IG urges explicit prioritization of NPV over non-cost metrics in the Terms of Reference (TOR) and final IRP, emphasizing affordability and reliability constraints.

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.
