Analysis Highlights - Electric vehicles reduce carbon emissions, save customers money, and produce average ratepayer savings. However, higher up-front costs, insufficient infrastructure, range anxiety, and other factors are challenges to a...
AI summary Electric vehicles (EVs) and cold-climate heat pumps (ccASHP) reduce emissions and offer savings but face adoption barriers like cost and infrastructure. Time-of-use rates and vehicle-grid integration (V1G/V2G) can mitigate costs and peak impacts. ccASHP benefits depend on fuel prices, rebates, and system design, with hybrid systems recommended to manage winter peaks.
The economics of building electrification from the customer perspective can be more uncertain than a similar transportation analysis, dependent on current and uncertain future fuel prices and electricity rates, building type and size, coun...
AI summary The analysis compares building electrification economics to transportation, highlighting uncertainties due to fuel prices and technology. Current and best-in-class cold-climate heat pumps show net benefits, while hybrid systems reduce fossil use and peak impacts. However, large-scale adoption of standard heat pumps may increase system peaks, requiring careful consideration of cost trends and rate design.

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.
