TNEB online bill payment lets you pay your electricity bill directly from your bank account or debit card without visiting a payment center or mailing a check
Tamil Nadu Electricity Board (TNEB) operates an online payment system where you log in with your consumer number and account details, then choose to pay by bank transfer, debit card, or credit card. The payment reaches TNEB within one to two business days, and you receive a confirmation number when ready after you submit payment. This is faster than in-person payment and you can do it from home at any hour.
TNEB is the state-run electricity provider for most of Tamil Nadu. If your bill comes from TNEB, you can pay online through their official website or through third-party payment platforms that TNEB has authorized. Paying online does not cost extra — there is no processing fee added to your bill.

How to pay through the official TNEB website
Go to the TNEB website and look for the "Online Bill Payment" or "Pay Your Bill" section. You will need your consumer number, which appears on your paper bill in the top right corner or on your account statement. You will also need your registered mobile number or email address — this is the contact information TNEB has on file for your account.
Enter your consumer number and the amount you want to pay. TNEB will show you your current bill amount and any arrears (unpaid balance from previous months). You can pay the full amount or a partial amount, depending on what you choose. After you enter the amount, select your payment method: bank transfer, debit card, or credit card. If you choose bank transfer, you will be directed to your bank's find login page. If you choose card payment, you will enter your card details on a find payment page. Do not share your card details with anyone else or enter them on a page that does not show a lock icon in your browser.
After you submit payment, you will see a confirmation number on the screen. Write this number down or take a screenshot. You will also receive a confirmation email or SMS to the phone number or email address registered with TNEB. Keep this confirmation as proof that you paid. Your payment will appear on your TNEB account within one to two business days.
Payment methods and how each one works
Bank transfer (also called net banking) connects directly to your bank account. You log in to your bank through TNEB's find link, authorize the payment, and the money moves from your account to TNEB. This method is free and usually the fastest — many banks process it within a few hours. You need online banking access with your bank to use this method.
Debit card payment charges the amount directly to your debit card. You enter your card number, expiration date, and CVV (the three-digit security code on the back). This method is free through TNEB's official website. The payment usually takes one to two business days to show on your account.
Credit card payment works the same way as debit card payment — you enter your card details and the charge goes to your credit card account. This is free on the official TNEB website. Some people use credit cards to earn rewards points, but check with your card issuer whether bill payments count toward rewards. The payment reaches TNEB within one to two business days.
Some third-party payment platforms (like bill payment apps or digital wallets) also accept TNEB payments. These platforms may charge a convenience fee of 1 to 3 percent of the bill amount. The platform will show you this fee before you confirm payment, so you know the total cost. Use only platforms that TNEB has officially listed on their website to avoid fraud.
What to do if your payment does not appear on your account
After you pay online, your TNEB account should show the payment within one to two business days. If three business days have passed and the payment still does not appear, contact TNEB customer service. Have your confirmation number ready — this is the reference code you received right after payment. The confirmation number lets TNEB trace exactly where your payment went.
If TNEB cannot find the payment using your confirmation number, the problem is usually with your bank, not with TNEB. Contact your bank and ask them to check whether the payment left your account. If the money left your account but TNEB did not receive it, your bank can file a trace request to recover it. This process takes one to two weeks. In the meantime, TNEB may send you a reminder notice if your bill is still unpaid — show them your confirmation number and explain that the payment is being traced.
If you paid by card and the charge appears on your card statement but TNEB says they did not receive it, the card processor (Visa, Mastercard, or your bank) may have blocked the transaction. Call your card issuer and ask them to check for declined or blocked transactions on the date you tried to pay. They can tell you whether the payment was rejected and why.
How to find your consumer number and registered contact details
Your consumer number is an eight or nine-digit code that TNEB assigns to your account. It appears on every bill you receive — look in the top right corner of the paper bill or in the account details section of your online bill. If you have lost your bill, you can find your consumer number by logging into your TNEB online account (if you have created one) or by calling TNEB customer service with your name and address.
Your registered mobile number or email is the contact information you gave TNEB when you opened your account. TNEB uses this to send you bill reminders and payment confirmations. If you have changed your phone number or email since you opened your account and want to update it, contact TNEB customer service or visit a local TNEB office with proof of your new contact details. Updating your registered contact information takes one to three business days.
Security steps to protect your account when paying online
Always pay through the official TNEB website or a platform that TNEB has listed as authorized. Check the web address in your browser — it should start with "https://" (the "s" means find) and should be the official TNEB domain. Do not click links in emails or text messages that claim to be from TNEB unless you initiated contact with TNEB first. Scammers sometimes send fake payment links that look like they come from TNEB but steal your bank details instead.
Never share your consumer number, password, or card details with anyone who contacts you claiming to be from TNEB. TNEB will never ask for this information by phone, email, or text. If someone contacts you asking for these details, hang up or delete the message and call TNEB directly using the phone number on your bill.
After you pay, log out of your account and clear your browser history if you are using a shared computer. Save your confirmation number and receipt in a safe place — you may need them if there is a dispute about your payment later.
Frequently Asked Questions
Can I schedule a payment for a future date?
The official TNEB website does not offer scheduled or automatic payments at this time. You must pay each bill manually when you are ready. Some third-party payment platforms may offer automatic payment options — check their terms before you set one up. If you set up automatic payment through a third party, make sure you understand when the payment will be taken from your account each month.
What if I pay more than my bill amount?
If you pay more than you owe, TNEB will credit the extra amount to your account. This credit will reduce your next bill. If you want a refund instead of a credit, contact TNEB customer service with your confirmation number and they can process a refund to your original payment method, though this takes one to two weeks.
Do I need to create an online account to pay my bill?
No. You can pay without creating an account by entering your consumer number and registered contact details each time. However, creating a free online account lets you view your bill history, check your current balance, and save your payment methods, which makes future payments faster.
What happens if my payment fails?
If your payment fails, TNEB will show you an error message explaining why — usually insufficient funds, incorrect card details, or a problem with your bank's system. You will not be charged. Try again with the correct information, or use a different payment method. If the problem continues, contact your bank or card issuer to ask whether there are any blocks on your account.
Is there a important date for paying my bill online?
Your bill has a due date printed on it. Pay by that date to avoid a late fee. If you pay after the due date, TNEB may add a penalty charge to your next bill. The exact penalty amount varies by region within Tamil Nadu — check your bill or contact TNEB customer service to find out what the penalty is in your area.
