Tariff is nothing but a way of charging our bill depending upon the consumption with different charges. We know TNEB is providing 100 units of free electricity to all domestic consumers.

For example if we use 150 units of electricity within 60 days cycle we will be charged for only 50 units by deducting 100 units of free electricity. A report says due to this free electricity nearly 80 lakhs consumers are using electricity at free of cost.

The cost of unit consumed is distributed as energy charges, Fixed charges and consumption charges. The TNEB slab rates for domestic depends upon the number of unit consumed. It is tabulated as above.

How is TNEB electricity bill units calculated

Calculation of EB bill is very simple. It depends upon the power of the electric appliances and the number of hours we are using the appliance in a single day. Multiply it by the respective KWh rate.

What Is LT And HT In EB Bill?

  • LT and HT means low tension supply and high tension supply.
  • High tension supply is used for commercial purpose where heavy machines are equipped.
  • Low tension supply is the one used for domestic purpose. Here it is categorized based on the tariff as discussed earlier.

Electricity Bill Calculation Formula

1 UNIT = 1 KWHR OR 1000 WATTS

For eg 5000 W appliance is in operation for 2 hours

We say 5000/1000 = 5 kwhr for 1 hr 5 kw hence for 2 hours we get 10kw/hr and so 10 units is consumed.
