AI summary Table 10 presents the evaluated 2023 ARet gross energy and peak demand savings from appliance retirements, including refrigerator, freezer, and room air conditioner replacements. The data highlights the number of units retired, energy savings at the meter and generator, and peak demand savings, with refrigerators contributing the largest share of first-year energy savings.

Figure 4: 2023 Tracked and Evaluated Gross Energy Savings at the Generator As presented in [Table](#page-84-2) 11, gross GHG emission reductions were calculated by applying the Nova Scotiaspecific factor 11 for GHG emissions generated by e...

AI summary The document references Figure 4 and Table 11, which present 2023 tracked and evaluated gross energy savings at the generator and calculate gross GHG emission reductions using a Nova Scotia-specific factor applied to ARET gross savings.

AI summary Table 11 presents the evaluated 2023 ARet gross GHG emission reductions, including gross energy savings, the Nova Scotia-specific GHG emissions factor, and the resulting annual GHG emission reductions in tonnes of CO2 eq.

The retirement of appliances may have occurred due to the influence of ARet even if no application was submitted. This influence can be due to a number of factors such as better awareness about the energy impacts from keeping the appliance...

AI summary The document discusses how appliance retirements may occur due to the influence of ARet even without program applications, attributing these retirements as spillover effects. The methodology for calculating spillover is outlined in Appendix III, and no change in spillover levels has been observed since the last evaluation.

AI summary Table 13 presents the 2023 ARet Effects and NTGR for various appliance types, including free-ridership rates and spillover impacts. The table indicates that refrigerators, freezers, and air conditioners have higher free-ridership rates compared to smaller appliances like small refrigerators and freezers, with dehumidifiers showing no free-ridership.
