How a TANGEDCO commercial bill is calculated
Commercial (LT-V) electricity bills from TANGEDCO have two main parts: an energy charge for the units you consume, and a fixed charge based on your sanctioned load. Commercial tariffs are higher than domestic ones and are revised by TNERC, so this calculator keeps the rate fields editable — enter your current tariff and load to get an exact figure.
The calculation
Commercial energy rates are typically in the ₹7–₹9 per unit range for LT-V supply, with a per-kW fixed charge. Because the exact numbers change with each tariff order, always use the figures printed on your latest bill.
A worked example
500 units at ₹8.05 = ₹4,025 energy charge; 5 kW load at ₹120 = ₹600 fixed charge; estimated bill about ₹4,625 before electricity tax and any other levies.
Ways to control a commercial bill
- Power factor: poor power factor can attract penalties — install capacitors to stay within the required range.
- Sanctioned load: you pay fixed charges on the sanctioned load even if unused, so right-size it.
- Solar: a rooftop solar plant with net metering can cut the energy-charge portion significantly for daytime businesses.
- Read your bill: check the tariff category — a wrongly classified connection can cost you for years.
