Tamil Nadu commercial EB bill estimate
Use this commercial TNEB bill calculator to estimate a Tamil Nadu shop or small business EB bill from consumed units, connected load, energy rate, and fixed charge. It is a planning tool, not an official TANGEDCO or TNPDCL bill.
Enter the values from your meter reading and tariff category. Adjust the rate fields if your official tariff order or bill shows different values.
Commercial EB calculation steps
Commercial electricity billing depends on the service category, consumed units, connected load, and the current tariff order. The calculator keeps those inputs visible so you can test the amount before checking the official bill.
If your service uses demand charges, power factor penalties, time-of-day rates, or special category charges, treat this result as a quick estimate only.
A shop uses 750 units with 5 kW connected load. If the energy rate is ₹8.50 and the fixed charge is ₹100 per kW, the estimate is 750 × 8.50 plus 5 × 100.
TANGEDCO commercial tariff notes
Tamil Nadu commercial connections can differ from domestic services. Before relying on an estimate, check the service category, sanctioned load, billing period, and whether extra adjustments apply.
| Item | What to check | How it affects the bill |
|---|---|---|
| Service category | Confirm that the connection is commercial or shop/business use. | Commercial rates are not the same as domestic slab rates. |
| Consumed units | Use current reading minus previous reading. | Units multiplied by the energy rate create the energy charge. |
| Connected load | Use sanctioned load or connected load from the service record. | Load multiplied by fixed charge creates the fixed charge. |
| Official adjustments | Look for arrears, taxes, demand charges, penalties, or subsidies. | These can change the final payable amount beyond the estimate. |
For official tariff interpretation, use the latest TNERC tariff order and the official TANGEDCO / TNPDCL portal.
