Notable findings for each package include: ♦ Mixed -Fuel + 3 kW PV: Packages are cost effective and achieve savings for all climate zones using the On -Bill and TDV approaches. ♦ Mixed -Fuel + 3 kW PV + 5 kWh Battery: The packages are less cost effective as compared to the 3 kW PV only package and not cost effective for LADWP and SMUD service area. ♦ Mixed -Fuel + PV only: Packages achieve positive energy cost savings and are cost effective using the On -Bill approach for all climate zones except for LADWP territory (Us 6, 8, 9 and 16). Packages achieve positive savings and are cost effective using the TDV approach for all climate zones. ♦ Mixed Fuel + PV + 5 kWh Battery: Adding battery slightly reduces On -Bill B/C ratios but is still cost effective for all climate zones except for LADWP territory. Packages achieve savings and cost effective using the TDV approach for all climate zones. ♦ All -Electric + 3 kW PV: Packages are cost effective using the On -Bill and TDV approach for all climate zones except for CZ16 under PG&E service. ♦ All -Electric + 3 kW PV + 5 kWh Battery: Similar to minimal PV only package, adding battery is cost effective as well using the On -Bill and TDV approach for all climate zones except for CZ16 under PG&E service. ♦ All -Electric + PV only: Packages are cost effective and achieve savings in all climate zones for both the On -Bill and TDV approaches ♦ All -Electric + PV + 50 kWh Battery: Adding battery slightly reduces B/C ratios for both the On -Bill and TDV approaches. Packages are not cost effective for all climate zones except CZ6, CZ8 and CZ9 under LADWP service area. 79 2019-07-25 506
