Latest Answer: Yeah, the electricity tariff table given above is pretty accurate. Hence for an average domestic household, the average tariff is Rs. 2.80 per unit of electricity. The fixed charges of Rs. 20 for a single-phase connection or Rs. 60 for a three-phase connection have to be paid only by the consumers who use more than 40 units of electricity in a month. If you stay within the first slab of energy usage, then you just have to pay for your consumption and will be exempted from paying the minimum fixed charge
