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.
TNEB Electrical tariff Rate 2023-24:
As per the latest Provisional Tariff subsidy for FY 2023-24 by the Government of Tamil Nadu, TNEB domestic tariff is splitted by two such as the rate for one unit varies between the consumption less than 500 units and above 500 units.
Note: The per unit rate for the single phase and three phase are same.
Less Than 500 Units:
If the consumer’s consumption is less than 500 units means, they has to pay zero charges for the first 100 units, ₹2.25 for the next 100 unit such as consumption between 101 to 200, ₹4.5 for the units between 200 to 400 and ₹6 per unit for the consumption between 400 to 500 units.
| Power Range | Per unit(₹) | |
| >500 units | 0-100 | |
| 101-200 | 2.25 | |
| 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.
₹6 for the next 100 units between 401 to 500, ₹8 per unit between 501 to 600, ₹9 per unit for the 601 to 800 units, ₹10 for the next 801 to 1000 units. ₹ 11 per unit for the consumption for the all remaining units.
| Above 500 Units | 0-100 | |
| 101-400 | 4.5 | |
| 401-500 | 6 | |
| 501-600 | 8 | |
