Reliant's online bill pay system lets you make one-time payments or set up automatic payments from your bank account

Reliant Energy serves customers in Texas, and their bill pay system works through their website or mobile app. You can pay your full balance, a partial amount, or set up recurring payments that happen automatically each month. Payments typically post within one to two business days, though you can schedule them for a future date if you want to time them with your paycheck.

The system accepts payments from a checking or savings account. You'll need your Reliant account number (found on your bill) and your bank routing and account numbers. If you don't have online access set up yet, you'll create a username and password the first time you log in.

Key Takeaways

  • You can pay through Reliant's website or their mobile app using your bank account information.
  • One-time payments usually post within one to two business days, but you can schedule them in advance.
  • Automatic payments let you set a recurring date each month so you never miss a due date.
  • You'll need your Reliant account number and your bank's routing and account numbers to get your free guide.
  • If you're having trouble logging in or making a payment, Reliant's customer service can walk you through the process by phone.

Setting up a one-time payment online

Log into your Reliant account on their website or open the Reliant mobile app. From your account dashboard, look for a "Pay My Bill" or "Make a Payment" button — the exact wording varies slightly between the website and app. Click it and you'll be asked to enter the amount you want to pay.

Next, you'll select or add a bank account. If this is your first payment, you'll enter your bank's routing number and your account number. Reliant will ask whether it's a checking or savings account. Then you'll choose the date you want the payment to go through — either today or a future date up to several weeks out.

Review the details one more time before confirming. Reliant will show you a confirmation number and send you an email receipt. Keep that confirmation number in case you need to track the payment later.

Setting up automatic monthly payments

Automatic payments work the same way as a one-time payment, except they repeat on a date you choose each month. From the "Pay My Bill" section, look for an option that says "Automatic Payment," "Recurring Payment," or "Autopay." You'll enter your bank account information the same way you would for a one-time payment.

Then you'll pick the day of the month you want the payment to happen — many people choose the day after they get paid or a few days before the due date. Reliant will deduct the full current bill amount on that date each month. If you want to change the amount or the date later, you can log back in and adjust it anytime.

Automatic payments are useful if you want to avoid late fees and don't want to remember to pay each month. You can cancel or pause them at any time through your account.

What happens if a payment fails

If your bank rejects a payment — usually because of insufficient funds or an incorrect account number — Reliant will send you a notice. The payment won't go through, and your bill will still be due. You'll need to fix the problem and try again, either by making a new payment or updating your bank account information.

If you have automatic payments set up and one fails, Reliant may attempt it again a few days later. Check your account or your email for notices about failed payments so you can address them quickly and avoid a late fee.

Paying by phone or mail if you don't want to use online pay

If you prefer not to pay online, Reliant accepts payments by phone. Call the number on your bill and a representative can take a payment over the phone using your bank account information. There's no fee for this service.

You can also mail a check or money order to the address listed on your bill. Include your account number on the check so Reliant knows which account to credit. Mailed payments take longer to post — usually five to ten business days depending on mail delivery — so plan ahead if your due date is coming up soon.

Keeping track of your payment history

Once you log into your Reliant account, you can see a record of all payments you've made. This history shows the date you made the payment, the amount, and the date it posted to your account. If you ever need to dispute a charge or confirm that a payment went through, this record is where you'll find that information.

Reliant also sends email confirmations for each payment, so check your email inbox and spam folder if you're looking for a receipt. You can read or print these confirmations for your records.

Frequently Asked Questions

Can I pay my bill before the due date?

Yes. You can make a payment anytime, and paying early won't hurt you. If you schedule a payment for a date before your due date, it will post on that date and reduce what you owe. This is useful if you want to spread payments across the month or pay as soon as you get paid.

Is there a fee to pay my bill online?

No. Reliant doesn't charge a fee for online bill pay through their website or app. Paying by phone is also free. The only payment method that might have a fee is a third-party payment processor if you use one outside of Reliant's system, so stick with Reliant's official channels.

What if I schedule a payment but then want to cancel it?

You can cancel a scheduled payment as long as it hasn't posted yet. Log into your account, find the payment in your history, and look for a "Cancel" option. Once a payment has posted, you can't cancel it, but you can contact Reliant to discuss a refund or credit if there was an error.

How do I know if my automatic payment went through?

Check your Reliant account online — your balance should decrease by the payment amount. Reliant also sends email confirmations. If you don't see the payment posted within two business days, contact Reliant to confirm it was processed. You can also check your bank account to see if the money left your account.

What should I do if I can't log into my Reliant account?

If you've forgotten your password, use the "Forgot Password" link on the login page to reset it. If you don't have an account yet, you'll need to create one before you can pay online. Reliant's customer service team can also help you regain access by phone — the number is on your bill.
