Three ways to pay your CPS Energy bill

CPS Energy, the utility serving San Antonio and surrounding areas, lets you pay by phone, online, or in person. The fastest route is their website at cpsenergy.com, where you can pay immediately with a bank account or debit card. If you prefer not to use the internet, you can call their payment line, mail a check, or walk into a payment center.

Each method has different timing — online and phone payments post the same day, while mailed checks take 7 to 10 business days to reach CPS Energy. Knowing which method works for your situation helps you avoid late fees and keeps your service from being interrupted.

Key Takeaways

  • Pay online at cpsenergy.com using your account number, which appears on your bill or in your online account.
  • Phone payments go through immediately when you call the automated line, but you will need your account number and a bank account or debit card ready.
  • Mailed checks should include your account number on the check and be sent to the address printed on your bill; allow 7 to 10 business days for delivery and processing.
  • In-person payments at CPS Energy offices accept cash, check, debit card, and credit card, and the payment posts the same day.
  • Late fees apply if your payment is not received by the due date shown on your bill, regardless of which method you use.

Paying online through cpsenergy.com

Go to cpsenergy.com and select "Pay My Bill" from the homepage. You will need your account number, which is printed on your bill in the upper right corner. If you do not have your bill handy, you can log into your online account using your email address and password — if you have not created an account yet, you can set one up during the payment process.

Enter your account number and the amount you want to pay. CPS Energy lets you pay the full balance, the minimum amount due, or a custom amount. Choose your payment method: bank account (ACH transfer) or debit card. Bank account payments are free and post within one business day. Debit card payments also post the same day but may carry a small processing fee depending on your card type.

Review the payment details and confirm. You will receive an on-screen confirmation number immediately — save or print this for your records. CPS Energy will also send you an email confirmation if you provided your email address.

Paying by phone

Call CPS Energy's automated payment line at 210-353-2222. Have your account number and a bank account or debit card ready. The system will walk you through entering your account number, the amount to pay, and your payment method. Payments made before 8 p.m. Central Time post the same day; payments after 8 p.m. post the next business day.

You will receive a confirmation number at the end of the call. Write it down or take a photo of your screen showing the confirmation. If you have questions during the process or prefer to speak with a representative, you can press the option to transfer to a live agent, though wait times vary depending on call volume.

Paying by mail

Write a check payable to CPS Energy and include your account number on the check itself — write it in the memo line or on the back. Place the check in an envelope with the payment stub from your bill, which has your account number pre-printed. Mail it to the address shown on your bill's payment section.

CPS Energy's mailing address is typically listed as a P.O. Box in San Antonio. Mail takes 5 to 7 business days to arrive, and CPS Energy needs another 2 to 3 business days to process it after receipt. This means a check mailed today may not post to your account for 7 to 10 business days. If your due date is within the next week, use online or phone payment instead to avoid a late fee.

Do not mail cash. If you must pay by mail and do not have a checking account, purchase a money order at a grocery store or bank, make it payable to CPS Energy, and mail it the same way.

Paying in person at CPS Energy offices

CPS Energy operates payment centers in San Antonio where you can pay in person. Payments made before 5 p.m. on a business day post the same day; payments after 5 p.m. or on weekends post the next business day. You can pay with cash, check, debit card, or credit card.

Find the nearest payment location on cpsenergy.com under "Pay My Bill" or call 210-353-2222 for office hours and addresses. Bring your account number or your bill. If paying by check, write your account number on the check. If paying by card, the representative will process it on the spot and give you a receipt.

What happens if you miss the due date

Your bill shows a due date, usually 20 to 25 days after the bill is issued. If your payment is not received by that date, CPS Energy charges a late fee. The amount of the late fee varies but is typically a percentage of your bill or a flat amount — check your bill or account online to see the exact fee.

If you are more than 30 days late, CPS Energy may send a disconnection notice. This gives you a window to pay before your service is shut off, usually 10 to 15 days. If you cannot pay the full amount, contact CPS Energy immediately to discuss a payment plan or hardship options. Waiting until after disconnection makes the process harder and more expensive.

Setting up automatic payments

If you want to stop thinking about due dates, you can set up automatic payments through your online account at cpsenergy.com. Log in, go to "Billing & Payments," and select "Autopay." You can choose to pay the full bill, a fixed amount, or the minimum due each month on a date you select.

Automatic payments come from your bank account and are free. You can change or cancel autopay anytime through your online account. CPS Energy will send you an email reminder before each automatic payment is processed, so you can catch any errors before the money leaves your account.

Frequently Asked Questions

What if I do not have an online account?

You can still pay without creating an account. On cpsenergy.com, select "Pay My Bill" and enter your account number and zip code. The system will let you pay as a guest. To set up autopay or view your payment history, you will need to create an account, which takes about five minutes and requires your email address and a password.

Can I pay someone else's CPS Energy bill?

Yes. Online or by phone, enter the account number of the person whose bill you are paying. You do not need to be the account holder. In person, bring the account number or bill. CPS Energy does not require you to prove a relationship to the account.

What if my payment was rejected?

Online or phone payments are usually rejected because the bank account or card information is incorrect or the account does not have enough funds. CPS Energy will tell you the reason immediately. Correct the information and try again, or use a different payment method. If the problem persists, call 210-353-2222 to speak with a representative.

How do I know if my payment went through?

You will receive a confirmation number immediately after paying online or by phone. Check your email for a confirmation message from CPS Energy. You can also log into your online account and view your payment history under "Billing & Payments." Payments typically show within one business day.

Can I pay with a credit card?

In-person payments accept credit cards. Online and phone payments accept debit cards and bank accounts, but not credit cards. Some third-party payment processors allow credit card payments for a higher fee, but CPS Energy's direct channels do not.
