Topic:"Cost Effectiveness" in M11307

an and should be welcome to bid in such an RFP, allowing for a fair and complete comparison of these alternatives to minimize cost and risk to ratepayers while meeting system reliability requirements. Third, to the extent NSPI conducts tec...

AI summary The text emphasizes NSPI's need to use competitive procurement to compare resource alternatives, avoid restrictive RFP quantity targets, and consider market-driven pricing. It highlights IRP scenarios showing how wind and battery cost variations affect project timelines and retirement schedules, advocating for flexible procurement designs like 'price-to-beat' benchmarks. Regional cooperation via external control areas is also recommended to incentivize transmission investments.

G. Demand-Side Management (DSM) Programs Our comments on the final model results raised quesfions about the finding that higher levels of DSM investment do not show a reducfion in either cost or emissions. We asked for further explanafion...

AI summary Stakeholders question NS Power's model results showing minimal cost/emission reductions from higher DSM investment, noting a $7 million savings claim is counterintuitive. NS Power ignored this in their response, and the Board is urged to await further analysis before relying on these results.

that correctly iden�fying the need for capacity is paramount for all subsequent IRP runs. The study should also ask whether energy to meet those peak demands should be stored in a batery, a tank, a lake or in a regionally linked, diversifi...

AI summary The text discusses the importance of accurately identifying capacity needs for Integrated Resource Plan (IRP) runs and the need to evaluate energy storage options. It also highlights concerns regarding the effectiveness of Demand-Side Management (DSM) programs, particularly the MMDSM scenario, which is more expensive than the Base DSM plan despite some energy and capacity savings.

AI summary The text emphasizes the importance of accurately identifying capacity needs for Integrated Resource Plan (IRP) modeling and discusses energy storage options for meeting peak demands. It also highlights the need for clear standards in evaluating resource options and considers how customer behavior, especially regarding heat pumps, may evolve with increasing carbon prices and aging backup equipment. Additionally, it addresses the complexities in interpreting Net Present Value of Resource Recovery (NPVRR) results from Demand-Side Management (DSM) scenarios.

Scope of Analysis in this Report As noted above, this report provides results from two key analyses. To assess the cost-effectiveness of electrification 4 , E3 analyzed the marginal costs and benefits of building and transportation electri...

AI summary This report evaluates electrification's cost-effectiveness using three tests: Participant Cost Test (PCT), Ratepayer Impact Measure (RIM), and Societal Cost Test (SCT). It analyzes marginal costs and benefits of electrification from adopter, ratepayer, and provincial perspectives, considering Nova Scotia Power's grid greening and renewable energy integration impacts on marginal costs over time.

Key Finding 2. Most transportation electrification investments produce benefits that exceed costs from the perspective of drivers, utility ratepayers and Nova Scotia. While electric vehicles have higher up-front costs today, drivers benefi...

AI summary Transportation electrification investments, including EVs and transit buses, yield net benefits for drivers, ratepayers, and Nova Scotia due to lower long-term costs, avoided emissions, and federal rebates. Time-of-use rates and battery cost declines further enhance economic viability, though supply chain uncertainties persist.

4.2.1 Cost and Benefit Categories in Transportation BCA The model considers significant and measurable categories of benefits and costs. A brief description of each estimated cost/benefit component included in the transportation BCA is pro...

AI summary The text outlines the cost and benefit categories considered in a transportation benefit-cost analysis (BCA), including incremental EV costs, incentives, O&M savings, fuel savings, electricity supply and infrastructure costs, electricity bills, and avoided emissions. It references the California Public Utility Commission's standard practice manuals for cost-effectiveness analysis.

4.4 Building Benefit-Cost Analysis Results [Table 4-9](#page-69-0) summarizes the results of the building electrification BCA for a select configuration of representative buildings adopting heat pumps for space heating. In general, the cus...

AI summary The benefit-cost analysis of building electrification in Nova Scotia shows that heat pumps are cost-effective for single-family homes, especially with current fuel prices. However, best-in-class heat pumps require additional incentives due to higher upfront costs. The analysis is sensitive to fuel oil prices, electricity rates, and capital costs, with assumptions based on Nova Scotia Power's experience and the Evergreen IRP Scenario 3.1C.

Hydro assumptions NSP includes refurbishment of all hydro assets, despite a lack of UARB approval or evidence of stakeholder acceptance. NRR would like to see all hydro assets which are up for capital renewal – using reasonable and agreed...

AI summary NSP proposes refurbishing hydro assets without UARB approval or stakeholder evidence, while NRR advocates comparing hydro renewal costs against new resources using agreed-upon assumptions in the planning exercise.

2.1 Notable Findings and Observations - NS Power provides several findings and observations throughout the Evergreen IRP in relation to - capacity addition and generation mix, as well as load and energy efficiency. E1 views many of these -...

AI summary NS Power outlines the Bi-Directional Atlantic Loop scenario in its Evergreen IRP, involving renewable energy exchange with Hydro Quebec. E1 critiques the project's $7.5B cost (up from $2.9B in 2020), citing unclear definition, evolving scope, and added construction risks from required wind capacity. Bates White's analysis and NB Power's views are also noted as risks.

7. CONCLUSION - E1 appreciates the opportunity to provide comments on, and recommendations related to NS - Power's updated Action Plan and Roadmap and appreciates the opportunity to participate - throughout the 2022 Evergreen IRP Process....

AI summary E1 provides seven recommendations to NS Power regarding the 2022 Evergreen IRP Process, emphasizing criteria evaluation, scenario risk analysis, hybrid peak solution clarity, DSM study limitations, NPVRR interpretation, and risk matrix development for IRP scenarios.
