TNEB Electricity Bill Calculator (Tamil Nadu)

Frequently Asked Questions (FAQ) - TNEB Bills & TANGEDCO Calculator

How are fixed charges handled for TNEB Domestic (LT-IA) connections in this tneb bill calculator?

This TNEB bill calculator includes a common bi-monthly fixed charge of ₹40 (₹20/month) for domestic (LT-IA) estimations. This typically applies to connections with a load up to 2 kW. Official TNEB fixed charges, as per TANGEDCO guidelines, can vary if your connected load is above 2 kW (typically ₹35/kW/month, i.e., ₹70/kW bi-monthly). This tool uses the common ₹40 for simplicity in its primary calculation for your electricity bill.

Why are fixed charges part of a TNEB bill?

Fixed charges cover TNEB's cost of maintaining the electricity infrastructure (poles, wires, etc.) to ensure a reliable power supply in Tamil Nadu, regardless of your actual energy consumption. These are standard for most electricity consumption bills.

What if my actual fixed charge is different from the ₹40 used by this eb bill calculator tamil nadu?

If your actual fixed charge (based on your connected load from your TANGEDCO bill) is different from the assumed ₹40 bi-monthly, the total bill estimate from this tool will differ from your official TNEB bill by that fixed charge difference. The energy charge estimation based on eb bill slab rates will still be accurate.

How does the 'Domestic: Bill (₹) to Units' feature work in this tneb unit calculator?

When estimating units from a total bill amount for a domestic connection, the TNEB unit calculator first subtracts the assumed common fixed charge (₹40 bi-monthly) from your target bill amount. It then tries to find the unit consumption whose energy charge (plus this ₹40 fixed charge) closely matches your original target bill amount, helping you understand your tneb unit consumption.

What if my 'Domestic: Bill (₹) to Units' input amount for TNEB bill is less than ₹40?

If the target bill amount you enter for your TNEB bill is less than or equal to the assumed ₹40 fixed charge, it implies that the energy consumption (and thus energy charge) must be zero or negligible. In such cases, the calculator will likely estimate 0 units or a very low unit value up to 100 units (which are subsidized as part of the tneb free units scheme). For example, if you consume exactly 100 free units (which have ₹0 energy charge), your bill would consist only of the fixed charge (e.g., ₹40). If your target is, say, ₹42.25, it means you've consumed the 100 free units plus 1 unit at ₹2.25, so total 101 units.

Does the 100 units free subsidy (tneb free units 2025) apply if my consumption is high, say over 500 units?

Yes, for domestic LT-IA connections in Tamil Nadu, the energy charge for the first 100 units is typically ₹0.00 (TNEB free units 2025 subsidy) regardless of your total bi-monthly consumption. However, the per-unit rates for subsequent eb bill slab rates increase significantly for higher overall consumption. This TNEB electricity bill calculator models this common subsidy approach.

What are the key components of a TNEB domestic electricity bill?

1. Fixed Charges: A bi-monthly charge based on your connected load.
2. Energy Charges: Calculated based on the units (kWh) consumed, applied through a slab-based tariff system (eb bill slab rates). The first 100 units usually have a subsidized energy charge (tneb free units).
3. Electricity Duty/Tax: A percentage or fixed amount levied by the state government on the energy charges or total bill. (NOT included in this calculator's estimate).
4. Other Charges: Potentially meter rent (if applicable), arrears from previous bills, penalties for late payment, etc. (NOT included in this calculator's estimate). You'd see these on your official TANGEDCO bill, accessible via your consumer number tneb on the TNEB online bill payment portal or through a TNEB digital bill viewer.

Why is the Commercial (LT-V) tneb bill calculator simplified to 'Energy Charge Only'?

TNEB Commercial (LT-V) tariffs in Tamil Nadu are significantly more complex than domestic ones. They usually involve:

• Higher Fixed Charges.
• Demand Charges based on sanctioned/recorded maximum demand (kW/kVA).
• Power Factor penalties or incentives.
• Potentially Time-of-Day (ToD) tariffs where unit rates vary during peak, off-peak, and normal hours.
• Higher electricity duty/taxes.

Due to this complexity and variability, the commercial tab in this TANGEDCO calculator provides a very basic estimation of energy charges only using a simplified slab structure. It does NOT attempt to calculate the full commercial bill which would be available through official TNEB channels.

How can I find my official TNEB 'Connected Load' or 'Sanctioned Load' for accurate bill calculation?

Your 'Sanctioned Load' or 'Connected Load' (usually in kW or kVA) is often printed on your physical TNEB electricity bill. You can also find this information by logging into your account on the TANGEDCO online portal (useful for TNEB online bill payment and checking TNEB application status 2025 for services like TNEB new connection online 2025), or by contacting your local TNEB office. Knowing this is important for understanding your applicable fixed charges if you want to compare this tool's estimate to your official TANGEDCO bill more accurately. Your consumer number tneb is also vital for accessing official details like online eb bill check tamil nadu.

How to calculate eb bill in tneb?

To calculate your TNEB EB bill: 1. Note your total bi-monthly units consumed. 2. Subtract the first 100 units (which are free under the tneb free units subsidy). 3. Apply the respective TNEB tariff slab rates to the remaining units. 4. Sum up the charges from all applicable slabs to get the energy charge. 5. Add the fixed charge (this calculator assumes ₹40 bi-monthly for domestic LT-IA). The total is your estimated bill. For official figures, always check your TANGEDCO bill or use the tneb online bill payment portal.

What are the current TNEB tariff slab rates for domestic connections (eb bill slab rates)?

This TNEB bill calculator uses the following illustrative domestic (LT-IA, Bi-Monthly) eb bill slab rates: 0-100 Units: ₹0.00 (Subsidy); 101-200 Units: ₹2.25/unit; 201-400 Units: ₹4.50/unit; 401-500 Units: ₹6.00/unit; 501-600 Units: ₹8.00/unit; 601-800 Units: ₹9.00/unit; 801-1000 Units: ₹10.00/unit; Above 1000 Units: ₹11.00/unit.
