What is an Tariff?
A tariff is a method of charging varying fees on your power bill based on use. If you have spent 600 units, for example, you will receive a different fee for each level of unit consumption. You receive little compensation for low levels up to 100 units, a modest increase for a subsequent level up to 200 units, and another meagre increase for levels over 500 units.
Tariff Rate Details for TNEB 2023
According to the Government of Tamil Nadu’s most recent Provisional Tariff Subsidy for FY 2023–2024, the TNEB domestic tariff is divided in half, with the pricing for one unit varying depending on whether 500 units or more are consumed.
The per unit charge for single phase and three phase is the same, please note.

Domestic/House Bill Calculator for TNEB
Let’s figure out the 263 units’ power bill. The cost is 0 (100100) for the first 100 units, 225 (2.25100) for the following 101 to 200, and 283.5 (4.5 *63) INR for the final 63 units.
In this case, our total bill comes to 508.5.
