. 7 HVAC replacements (gasto-heat pump) . 5 Hybrid Water Heaters (gasto-electric) . 2 Clothes Dryer Replacements (Gasto-Electric) . 4 Stove Replacements (gasto-lnduction) Based on these assumptions, we estimate that we will reduce emissions based on electrification by 221.5 short tons over the next 15 years through the electrification efforts associated with this project. ln addition to the electrification work, we assume grid-level emissions reduction due to the energy efficiency work of weatherization and repair. This is harder to quantify, but we'll take a shot. The NC Department of Environmental Quality website states that weatherization can save participants around $300 per year on their energy bills. Using the Duke Energy Carolina's average rate, the number of homes we plan to serve, and DEC's 2021 Emissions factor, we can do a little math: $300 savings x $.1057 per kwh = 2838 kwh saved/yrlhome 20 homes x 2B3B kwh = 56,764 kwh saved/yr 56,764 kwh/yr x 15 yr = 851,466 kwh saved ever 15-yr period 851,466 kwh x DEC 2021 Emissions Factor 0.48 = 408,703 lbs 408,703 lbs of CO2 I 2000 = 204.25 short tons over 15 years ln total, based on our estimates, we expect that we can avoid carbon emissions of 425.75 short tons over 15 years with this project. 2L, For how many years will this emissions reduction take place as a result of your project? Please consider the expected lifetime of the tech nology/progra m/i m pact etc. We hope that these changes will have a lasting impact on emissions reduction, but for the purposes of this application, we are assuming a 15-year time horizon for the emissions reduction. That mirrors the life expectancy of most appliances and the other improvements RTT intends to make in these homes. 22. Please describe the location of the emissions reduction. Where would fossilfuels have been burned if not for your project? For projects creating electricity usage reductions, it can be difficultto determine the location of the power produced. Please feel free to state "Grid-tied electricity reduction" Some of the reduction will be grid-tied electricity - projects like insulation, air sealing and other energy efficiency interventions. For the beneficial electrification interventions like water heaters, induction stoves and other appliances, we will be reducing emissions from combustion within individual homes. We estimate that about 60% of the reduction will come at the grid level, with the remaining 40% coming at the individual home, however, those percentages could shift based on what work is actually completed in each home served.
