The fastest way to pay CPS Energy is online through their website or mobile app, by phone, or in person at a payment location

CPS Energy serves the San Antonio area. You can pay your bill the same day you receive it, and you have several ways to do it depending on what works for your schedule. Online and mobile payments usually post within one business day. Phone payments and in-person payments at authorized locations process immediately.

Your bill arrives by mail or email, depending on how you signed up. The due date is printed on the front of your bill — typically 20 to 21 days after the bill date. Paying by the due date keeps you from owing a late fee.

Key Takeaways

  • CPS Energy's website and mobile app let you pay anytime without calling, and payments post within one business day.
  • Phone payments at 210-353-2700 process the same day, but you will need your account number and a payment method ready.
  • In-person payment locations include CPS Energy offices and authorized retailers like H-E-B and Walmart, where you can pay cash or card immediately.
  • Setting up automatic payments through your bank or CPS Energy's autopay program removes the risk of missing a due date.
  • Late fees apply if you pay after the due date printed on your bill, so mark that date on your calendar or set a phone reminder.

Paying online or through the CPS Energy mobile app

Go to cpsenergy.com and log into your account. If you do not have an online account yet, you can create one using your account number (printed on your bill) and your service address. Once logged in, select "Pay My Bill" and enter the amount you want to pay.

You can pay with a debit card, credit card, or bank account. CPS Energy does not charge a fee for debit or bank account payments, but credit card payments carry a fee of about 2.5 percent. The payment posts to your account within one business day.

The CPS Energy mobile app works the same way. Download it from the Apple App Store or Google Play, log in with the same username and password you use on the website, and follow the same steps. Mobile payments process on the same timeline as website payments.

Paying by phone

Call CPS Energy at 210-353-2700 to pay by phone. Have your account number and a debit card, credit card, or bank account information ready. The automated system will walk you through the payment. If you prefer to speak with a representative, you can stay on the line after the automated menu.

Phone payments process immediately. The payment shows up in your account right away, though it may take one business day to appear on your next bill statement. Like online credit card payments, phone payments by credit card carry a fee.

Paying in person at a CPS Energy office or authorized location

CPS Energy has payment locations throughout San Antonio. The main office is at 500 W. Market Street, but there are several others. You can also pay at authorized retailers including H-E-B, Walmart, and other locations listed on the CPS Energy website.

Bring your bill or account number and your payment method — cash, check, debit card, or credit card. In-person payments process immediately. If you pay by check, write your account number on the check so CPS Energy can match it to your account.

Setting up automatic payments to avoid late fees

CPS Energy's autopay program deducts your payment from your bank account on a date you choose each month. You can set it up on the website under "Billing & Payment" or by calling 210-353-2700. Autopay is free and removes the risk of forgetting to pay by the due date.

You choose the payment amount — you can pay the full bill, a fixed amount, or just the minimum. You can change or cancel autopay anytime. If your bill varies month to month, you may want to set autopay for a fixed amount slightly less than your average bill, then pay any remaining balance manually when the bill arrives.

What happens if you miss the due date

A late fee applies if your payment is not received by the due date on your bill. The fee amount depends on your bill size. If you are more than 30 days late, CPS Energy may disconnect your service. If that happens, you will owe a reconnection fee in addition to your unpaid balance.

If you cannot pay the full bill by the due date, contact CPS Energy before the due date passes. They may be able to set up a payment plan that lets you pay in installments. Calling ahead is better than waiting — it shows you are working to resolve the debt and may help you avoid disconnection.

Understanding your account number and how to find it

Your account number is a unique identifier for your service address. It appears on your bill, in the top right corner usually. You will need it to pay by phone, set up autopay, or log into your online account.

If you cannot find your account number, log into your online account on cpsenergy.com, call 210-353-2700, or check an old bill. Keeping your account number handy makes payments faster, especially if you pay by phone or in person.

Frequently Asked Questions

Can I pay my CPS Energy bill with a credit card without a fee?

No. CPS Energy charges a fee of roughly 2.5 percent for credit card payments, whether you pay online, by phone, or in person. Debit card and bank account payments have no fee. If you want to use a credit card, factor the fee into your decision.

What if I pay online but my payment does not show up right away?

Online payments post within one business day. If you pay on a Friday evening, it may not appear until Monday. If more than one business day has passed and you do not see the payment, log into your account to confirm it went through, or call 210-353-2700 to check the status.

Can I set up autopay to pay a different amount each month?

No. Autopay deducts a fixed amount you choose. If your bill varies, set autopay for a lower amount and pay the difference manually when the bill arrives, or turn off autopay and pay manually each month.

What if I want to pay my bill but I do not have a bank account or credit card?

You can pay in cash at authorized retailers like H-E-B or Walmart, or at a CPS Energy office. Bring your bill or account number. Cash payments process immediately and do not carry a fee.

Is there a penalty for paying early or paying more than the due amount?

No. You can pay anytime before or after the bill arrives, and you can pay more than the amount due. Overpayments stay on your account as a credit toward your next bill.
