CPS Energy offers three main ways to pay your bill online: through their website, through their mobile app, or by setting up automatic payments from your bank account
The fastest route is CPS Energy's website at cpsenergy.com. You log in with your account number and password, then choose a one-time payment or set up recurring payments. The site accepts debit cards, credit cards, and bank account transfers. Payment goes through immediately for card payments; bank transfers typically post within one business day.
If you prefer using your phone, CPS Energy has a mobile app available on both iOS and Android. The app works the same way as the website — you enter your account details, choose your payment method, and confirm. Many people find the app easier for quick payments when they're away from home.
The third option is automatic payments, which means CPS Energy withdraws money from your bank account on a set date each month. This removes the step of logging in and paying manually. You set it up once through the website or by calling CPS Energy at 210-353-2222, and the payment happens on its own.

Paying through the CPS Energy website
Go to cpsenergy.com and look for the "Pay My Bill" link, usually near the top of the page. Click it and you will be asked to log in. If you do not have an online account yet, you can create one using your account number, which appears on your paper bill or in any email CPS Energy has sent you.
Once logged in, your current bill amount appears on the screen. You can pay the full amount or a partial payment. Choose your payment method: debit card, credit card, or bank account. If you use a card, you may see a small convenience fee added — CPS Energy does not charge this; the payment processor does. Bank account payments have no fee.
After you enter your payment details and confirm, you will see a confirmation number. Write it down or take a screenshot. The payment is complete, and you should receive an email receipt within a few minutes.
Using the CPS Energy mobile app
Download the CPS Energy app from the Apple App Store or Google Play. Open it and log in with the same account credentials you use on the website. Your current bill and due date appear on the home screen.
Tap "Pay Now" or the payment option, then enter the amount you want to pay. Select your payment method and confirm. The app works identically to the website, so the same fees and processing times apply. You will receive a confirmation number and an email receipt.
The app also shows your usage history and lets you set payment reminders, which can help you avoid late payments. Some people set a reminder for a few days before the due date so they have time to pay without rushing.
Setting up automatic payments
Automatic payments mean CPS Energy withdraws money from your bank account on the same date each month. You choose the date — many people pick the day after they get paid. Once set up, you do not have to think about it again unless you want to change the amount or date.
To set up automatic payments, log into your account on cpsenergy.com, go to "Billing & Payment," and select "Automatic Payment." You will enter your bank account number and routing number. CPS Energy will make a small test deposit (usually under $1) to verify the account, then withdraw it back. After that, your monthly payment happens automatically.
You can also set up automatic payments by calling CPS Energy at 210-353-2222 and speaking to a representative. Have your bank account information ready. Automatic payments can be changed or stopped anytime through your online account or by calling.
What to do if your payment does not go through
If you see an error message when you try to pay, the most common causes are a mistyped account number, an expired card, or insufficient funds in your bank account. Check your account number on your bill and try again. If you are using a debit or credit card, make sure it has not expired and that you have available funds or credit.
If the problem persists, call CPS Energy at 210-353-2222. A representative can process your payment over the phone using the same payment methods available online. They can also tell you if there is a temporary issue with the website or app.
If your automatic payment fails — for example, because your bank account closed — CPS Energy will send you a notice. Contact them right away to update your payment method or arrange an alternative. A failed automatic payment can result in a late fee if not corrected quickly.
Payment deadlines and late fees
Your due date appears on your bill. If you pay online by that date, your payment counts as on time. For card payments, the money leaves your account immediately, so paying the day before the due date is safe. For bank account transfers, allow one business day, so pay by the day before the due date to be certain.
If your payment arrives after the due date, CPS Energy charges a late fee. The amount varies but is typically a percentage of your bill. Automatic payments help avoid this because the withdrawal happens automatically on the date you choose.
If you know you cannot pay by the due date, contact CPS Energy before that date. They may be able to extend your due date or set up a payment plan. Calling ahead is much better than paying late, because it can prevent the late fee and keeps your account in good standing.
Paying if you are behind on your bill
If you owe money from a previous month, you can still pay online. When you log into your account, you will see the total amount owed, which includes the current bill plus any arrears. You can pay the full amount or make a partial payment toward what you owe.
If you cannot pay the full amount at once, contact CPS Energy at 210-353-2222 to discuss a payment plan. They may allow you to spread the arrears over several months while you also pay your current bill. This keeps your service from being disconnected and gives you time to catch up.
Some customers also may have access to for hardship programs or bill assistance through CPS Energy or local nonprofits. CPS Energy can tell you what programs may be available based on your situation. It is worth asking about before your account falls too far behind.
Frequently Asked Questions
Is there a fee to pay my CPS Energy bill online?
CPS Energy does not charge a fee for online payments. However, if you pay with a credit card or debit card, the payment processor may add a small convenience fee — usually 2 to 3 percent of the amount. Bank account payments have no fee. Automatic payments also have no fee.
How long does it take for my online payment to show up on my account?
Card payments process immediately and show on your account right away. Bank account transfers typically post within one business day. Automatic payments withdraw on the date you set and post within one business day after that.
Can I pay someone else's CPS Energy bill online?
You can pay another person's bill if you have their account number. Log into the CPS Energy website, enter their account number instead of yours, and proceed with payment. You will need a payment method in your name, but the payment goes to their account.
What should I do if I do not remember my online account password?
On the CPS Energy login page, click "Forgot Password." Enter your account number and email address, and CPS Energy will send you a reset link. Follow the link to create a new password. If you do not receive the email, check your spam folder or call 210-353-2222 for help.
Can I set up automatic payments if I have a variable income?
Yes, but you have two options. You can set a fixed automatic payment amount each month, knowing some months you will pay more than your bill and others less. Or you can log in manually each month and pay what you owe. Some people use automatic payments for a base amount and then pay the difference manually in months when their bill is higher.
