What is Tariff:

The way of charging your electricity bill based on the consumption with different charges is called a tariff. i.e you have consumed 600 units means, you get different prices for each step of unit levels. You get small money for low units up to 100 and small amount hike with another level up to 200 units and again small hike for 500 units levels.

201-400 4.5
401-500 6

 

More than 500 Units:

In case, if the consumer consumes more than 500 units (even if one unit extra) then they shall pay ₹0 for the first 100 units, ₹4.5 per unit for next 300 units such as 101 to 400.
