How TNEB bill payment works
TNEB (Tamil Nadu Electricity Board), now operating as TANGEDCO (Tamil Nadu Generation and Distribution Corporation), sends you a bill each month for the electricity you used. You can pay that bill in three main ways: online through the TANGEDCO website or mobile app, by mail with a check or demand draft, or in person at an authorized payment agent or TANGEDCO office. Payment is due by the date printed on your bill — if you miss that date, TANGEDCO adds a late fee and may disconnect your power.
Your bill shows your consumer number (a unique ID for your connection), the amount due, and the due date. Keep this number handy for any payment method you choose. The bill also shows your meter reading, how many units you used, and the rate per unit, so you can understand what you are paying for.
Key Takeaways
- TANGEDCO bills must be paid by the due date shown on your bill, or you will face a late fee and risk disconnection.
- Online payment through the TANGEDCO website or authorized apps is the fastest method and gives you an instant receipt.
- You can pay at authorized agents, TANGEDCO offices, or banks across Tamil Nadu without needing internet access.
- Paying by mail takes longer and requires you to send a check or demand draft; keep a copy of your bill as proof.
- Your consumer number is required for every payment method, so locate it on your bill before you start.
Paying online through TANGEDCO's website or app
The TANGEDCO website (tangedco.gov.in) has a bill payment portal where you enter your consumer number and the amount due. You can pay using a debit card, credit card, or net banking from most Indian banks. The payment is processed immediately, and you receive a confirmation number on screen — write this down or take a screenshot, as it serves as your receipt.
TANGEDCO also has a mobile app available on Android and iOS. The app works the same way: enter your consumer number, review the bill amount, and pay by card or net banking. The app may also show your payment history and upcoming due dates, which can help you plan ahead.
Online payment carries no extra fee beyond what TANGEDCO charges for the electricity itself. The transaction is secure, and your payment reaches TANGEDCO's account within hours. If you do not receive a confirmation number, contact TANGEDCO customer service before assuming the payment went through — sometimes a payment fails silently if your bank connection drops.
Paying in person at agents and TANGEDCO offices
TANGEDCO has authorized payment agents at post offices, banks, and dedicated collection centers across Tamil Nadu. You can walk in with your bill, give your consumer number and the amount due to the agent, and pay in cash or by check. The agent will give you a receipt stamped with the date and payment amount — keep this until your next bill arrives to confirm the payment was recorded.
You can also pay directly at TANGEDCO offices in your district. These offices are open during business hours (usually 9 a.m. to 5 p.m., Monday through Friday). Bring your bill and your consumer number. Payment in cash is fastest; if you pay by check or demand draft, ask the office staff when the payment will be recorded in their system, as it may take a few days to clear.
In-person payment is useful if you do not have internet access or prefer not to use cards online. The downside is that you must travel to an agent or office during their hours, and if you go near the due date, you risk arriving after they close or after the deadline has passed.
Paying by mail with check or demand draft
You can mail a check or demand draft to TANGEDCO along with a copy of your bill. Write your consumer number on the back of the check. Mail it to the TANGEDCO office address for your district (this address is usually printed on your bill or available on the website). Keep a photocopy of your bill and the front and back of your check as proof of payment.
Payment by mail is slow. The check must arrive at TANGEDCO, be opened, recorded, and cleared by the bank — this process typically takes two to three weeks. If your due date is within a week, do not use mail; you risk a late fee or disconnection. Mail payment is most useful if you are paying well in advance or if you have no other way to send money.
If you mail a check and do not see the payment recorded on your next bill, contact TANGEDCO with your proof of mailing. Checks can be lost or delayed, so having documentation protects you if there is a dispute.
What happens if you miss the due date
If you do not pay by the due date on your bill, TANGEDCO adds a late fee (the amount varies by state rules and your bill size). Your next bill will show both the original amount and the late fee. You must pay both to bring your account current.
If you remain unpaid for 30 to 60 days (the exact timeline depends on TANGEDCO's policy), TANGEDCO may disconnect your power. A disconnection notice is usually sent before the actual cutoff, giving you a chance to pay and avoid it. Once disconnected, you must pay the full amount due plus a reconnection fee to restore power.
If you cannot pay the full amount by the due date, contact TANGEDCO immediately. Some regions offer payment plans or hardship programs for customers facing temporary difficulty, though availability varies. Calling or visiting an office before you miss the deadline gives you the best chance of working out an arrangement.
Finding your consumer number and bill details
Your consumer number is printed on every TANGEDCO bill, usually near the top in large text. It is a unique identifier for your electricity connection and is required for every payment method. If you have lost your bill, you can find your consumer number by logging into your TANGEDCO online account (if you have registered one) or by calling TANGEDCO customer service with your name and address.
Your bill also shows the due date, the amount due, your meter number, and a breakdown of charges. Read the bill carefully to make sure the amount matches what you expect. If you see an error or an unusually high charge, contact TANGEDCO before paying to ask about it — they can explain the charges or investigate if something is wrong.
Keeping records of your payments
Always keep proof of payment. If you pay online, save your confirmation number and take a screenshot of the receipt. If you pay in person, keep the stamped receipt from the agent or office. If you pay by mail, keep a photocopy of your check and bill. These records protect you if there is ever a dispute about whether you paid on time.
Check your next bill to confirm that your payment was recorded. Sometimes there is a delay between when you pay and when it appears on your account, especially for in-person or mailed payments. If a payment does not show up within two weeks, contact TANGEDCO with your proof of payment and ask them to investigate.
Frequently Asked Questions
Can I set up automatic payments so I do not have to pay each month?
TANGEDCO does not currently offer automatic recurring payments through their website or app. You must initiate each payment manually. However, some banks offer bill payment services where you can schedule a payment to TANGEDCO in advance; check with your bank about this option.
What if I pay online but do not get a confirmation number?
If your payment screen closes without showing a confirmation number, do not assume the payment failed. Check your bank account to see if the money was deducted. If it was, contact TANGEDCO customer service with your bank transaction details and they can look up the payment. If the money was not deducted, try paying again.
Can I pay someone else's TNEB bill if I have their consumer number?
Yes, you can pay another person's bill online or in person if you have their consumer number and the bill amount. You do not need to be the account holder. This is useful for paying a family member's or friend's bill, though some payment agents may ask for identification.
What is the difference between the amount on my bill and what I actually owe?
Your bill shows the electricity charges, taxes, and any other fees TANGEDCO adds. The total at the bottom is what you owe. If you paid part of a previous bill, that amount may be subtracted. If you are unsure what you owe, call TANGEDCO or check your online account — they can tell you the exact amount due today.
Can I get a refund if I overpay my TNEB bill?
If you pay more than the amount due, TANGEDCO will credit the extra amount to your next bill. You do not receive a cash refund. If you overpay significantly and want a refund instead, contact TANGEDCO to request one; they can process it, though it may take several weeks.
