TNEB Electricity Tariff Slabs in Tamil Nadu
TNEB electricity charges are calculated based on slab rates set by TANGEDCO. The tariff is divided into different slabs, and each slab has a fixed rate per unit. As electricity consumption increases, the per-unit cost also increases.
Domestic electricity consumers in Tamil Nadu are billed under a slab system. The first set of units may be charged at a lower rate or provided at no cost, while higher units are charged at higher rates. This slab-based system helps control electricity usage and ensures fair billing for consumers. Below are the current TNEB electricity tariff slabs for domestic users:
| Slab | Units | Rate per Unit |
|---|---|---|
| < 500 units | 0 – 100 | Free |
| 101 – 200 | ₹2.35 | |
| 201 – 400 | ₹4.70 | |
| 401 – 500 | ₹6.30 | |
| Above 500 units | 0 – 100 | Free |
| 101 – 400 | ₹4.70 | |
| 401 – 500 | ₹6.30 | |
| 501 – 600 | ₹8.40 | |
| 601 – 800 | ₹9.45 | |
| 801 – 1000 | ₹10.50 | |
| Above 1000 | ₹11.55 |
Note:
- The above slab rates are applicable for the bi-monthly billing cycle (usually 60 days).
- If your electricity bill covers less than 35 days, TNEB applies monthly slab rates, which are different.
- For example, if you consume 650 units in a month, the slab rates will be different than if you consumed the same 650 units over two months.
- This calculator uses the bi-monthly slab rates for accurate estimates.
Example of TNEB Electricity Bill Calculation for 650 Units
For example, if you consumed 650 units, your bill would be calculated as follows:
- First 100 units → ₹0
- Next 300 units (101–400) → 300 × ₹4.70 = ₹1,410
- Next 100 units (401–500) → 100 × ₹6.30 = ₹630
- Next 100 units (501–600) → 100 × ₹8.40 = ₹840
- Next 50 units (601–650) → 50 × ₹9.45 = ₹472.50
Total Bill = ₹0 + ₹1,410 + ₹630 + ₹840 + ₹472.50 = ₹3,352.50
So, your estimated bill for 650 units would be ₹3,352.50. This includes all the energy charges based on the slab rates. You can use this calculator to quickly estimate your bill for any number of units consumed.
