In this article, we present a detailed, step-by-step guide on how to use the Tamil Nadu Electricity Bill Calculator, including essential tips, tariff details, and insights to manage your energy consumption effectively.

Understanding the Tamil Nadu Electricity Tariff Structure

The Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO) determines the electricity tariff structure. The tariffs are based on consumer categories, with residential (domestic) users being the most common.

Key Tariff Components:

1. Units Consumed (kWh): Electricity usage is measured in kilowatt-hours (kWh).
2. Fixed Charges: A flat rate charged based on the connection type.
3. Variable Charges: Charges calculated based on the number of units consumed.
4. Additional Charges: Includes electricity tax and surcharges, if applicable.

The domestic tariff system operates on a slab-based pricing model, where the rate increases as the number of units consumed crosses certain thresholds.

How to Calculate Your Tamil Nadu Electricity Bill Manually

Step-by-Step Calculation:

1. Determine Units Consumed: Subtract the previous month’s meter reading from the current reading to find the total units consumed.
2. Apply Tariff Rates: Multiply the units in each slab by the corresponding rate. For example:
   • First 100 units: ₹1.50 per unit.
   • Next 100 units (101-200): ₹2.00 per unit.
   • Next 100 units (201-300): ₹3.00 per unit.
   • And so on.
3. Add Fixed Charges: A nominal fee based on your connection type, such as ₹30 for single-phase connections.
4. Include Additional Charges: Calculate 9% electricity tax on the subtotal.
5. Final Amount: Add all the charges to find your total bill.
