What is Included in Your TNEB / TANGEDCO Electricity Bill?
| Charge Component | Explanation |
| Energy Charges | Calculated slab-wise based on total units consumed in the billing month. TANGEDCO uses a cumulative slab system — higher consumption moves you into higher rate slabs. |
| Fixed Charges | A monthly demand charge based on your sanctioned load (kW). This is payable regardless of how many units you consume. |
| Fuel Surcharge | A quarterly variable charge to adjust for fluctuations in fuel costs for power generation. Revised by TNERC every quarter. |
| Electricity Tax | State government tax levied at 5% on your energy charges as per Tamil Nadu Taxation laws. |
| Meter Rent | A nominal monthly rental charge for the energy meter installed at your premises by TANGEDCO. |
| Delayed Payment Surcharge | 1.5% per month surcharge applied if bill is not paid by the due date mentioned on your bill. |
Tips to Reduce Your Tamil Nadu Electricity Bill
1. Tamil Nadu provides the first 100 units FREE every month to residential consumers — plan consumption to stay close to this threshold.
2. Use energy-efficient BEE 5-star rated fans, refrigerators, and ACs — they can cut consumption by 30–40%.
3. Shift heavy loads like washing machines and water heaters to off-peak hours (10 PM – 6 AM).
4. Apply for PM Surya Ghar Muft Bijli Yojana — get up to ₹78,000 subsidy on rooftop solar installation.
5. Fix meter faults immediately — a faulty meter can lead to estimated billing which is often higher than actual consumption.
6. Check your power factor if you have a commercial/industrial connection — maintain it above 0.90 to avoid surcharges.
