What is the possible saving for my electricity bill?
For an average household, the saving is around 10-20%, but the saving range may vary from 5-25%, it depends on the ratio of the Inductive load versus Resistive load used in the premise. If the usage pattern generate lots of Resistive load from appliances i.e. Iron, Oven, Water Heater, incandescent lights, etc. then the savings may be lower. In another extreme situation where the owner already invested extensively in energy saving appliances i.e. Inverter A/C system, energy efficient fridge and washing machine, extensive use of energy saving bulbs, etc, it is common sense that further savings will be minimal.
