How to Pay Your TXU Energy Bill

TXU offers three main ways to pay your bill: online through their website, by phone, or by mail

TXU Energy is a retail electric provider that serves customers in Texas. When your bill arrives, you have options for how and when to pay it. The fastest route is their online portal, which lets you pay when ready and see your payment post within one business day. Phone and mail payments work too, but take longer to process.

Your bill shows a due date — usually 21 days from the bill date. You can pay before that date, on it, or after it, though paying late may trigger a late fee. The amount you owe appears on your bill statement, and you can also log into your TXU account online to see what you currently owe.

Key Takeaways

• TXU's online payment portal at txu.com is the fastest way to pay, and payments post within one business day.
• You can also pay by phone by calling TXU's customer service line, or by mailing a check to the address on your bill.
• Setting up autopay through your TXU account means your bill gets paid automatically each month on a date you choose.
• Late payments may result in a fee, and non-payment can lead to service disconnection after a certain period.
• Your TXU account online shows your current balance, payment history, and due dates so you can track what you owe.

Paying online through the TXU website or app

Go to txu.com and log into your account using your username and password. If you don't have an online account yet, you can create one by entering your account number (found on your bill) and other identifying information. Once logged in, look for the "Pay My Bill" or "Make a Payment" option.

Enter the amount you want to pay — you can pay your full balance, a partial amount, or more than you owe. Choose your payment method: debit card, credit card, or bank account. TXU may charge a fee for credit card payments but not for debit card or bank account payments, so check before you submit. Review the details and confirm the payment. Your money should post to your account within one business day.

TXU also has a mobile app available on iOS and Android that works the same way. You can read it from the App Store or Google Play, log in with your account credentials, and pay from your phone.

Paying by phone or automatic payments

Call TXU's customer service number, which appears on your bill. A representative can take your payment information over the phone and process the payment when ready. Have your account number and payment method ready. Phone payments typically post within one to two business days.

If you want to avoid having to pay each month, set up autopay through your TXU account. Log in online, find the autopay or automatic payment section, and choose the date each month when you want your bill paid automatically. You can use a bank account or debit card. You can change or cancel autopay anytime through your account.

Paying by mail

Write a check or money order for the amount shown on your bill. Do not send cash. Include your account number on the check. Address the envelope to the mailing address printed on your bill statement — this address is where TXU processes payments.

Mail takes five to ten business days to arrive, so send it well before your due date to avoid a late payment. Keep a record of when you mailed it in case there is a question later. Once TXU receives and processes your check, it will post to your account, usually within three to five business days after arrival.

What happens if you miss a payment or pay late

If your payment does not arrive by the due date on your bill, TXU may charge a late fee. The amount varies, so check your bill or account for the specific fee. Continued non-payment can result in a disconnection notice, which gives you a window to pay before your service is shut off.

If you are having trouble paying your bill, contact TXU before the due date. They may be able to work out a payment plan or discuss other options. Some customers also may have access to for energy information programs through their state or local government, which can help with bill payments.

Viewing your balance and payment history

Log into your TXU account online to see your current balance, due date, and past payment history. This is useful if you want to confirm a payment went through or check what you still owe. Your online account updates regularly, though it may take a day or two for recent payments to show.

You can also call TXU customer service to ask about your balance or payment status. Have your account number ready. A representative can tell you exactly what you owe and when it is due.
