Call CPS Energy's automated payment line at 1-210-353-2222 to pay by phone
CPS Energy's phone payment system is available 24 hours a day, 7 days a week. When you call, you'll enter your account number and choose to pay with a debit card, credit card, or bank account. The system processes the payment immediately, and you'll receive a confirmation number before you hang up. Keep that number for your records.
If you prefer to speak with a representative instead of using the automated system, you can call CPS Energy's customer service line at 1-210-353-2222 and ask to be transferred. A representative can take your payment information over the phone and answer questions about your account at the same time. Customer service hours are Monday through Friday, 7 a.m. to 7 p.m. Central Time, and Saturday 8 a.m. to 5 p.m.
Have your account number ready before you call. You'll find it on your bill in the upper right corner, or you can look it up online if you have a CPS Energy account login. The payment will post to your account within one business day.

What payment methods CPS Energy accepts by phone
CPS Energy accepts three payment methods when you call: debit card, credit card, or electronic bank transfer (also called ACH or direct debit). Debit and credit cards are processed immediately. If you pay from a bank account, the payment typically posts within one business day.
There is no fee for paying by debit card or bank account. Credit card payments may carry a fee—CPS Energy does not charge it, but your credit card company or a third-party processor may. The automated system will tell you the fee amount before you confirm the payment, so you can decide whether to proceed.
How to avoid common mistakes when paying by phone
The most common mistake is not having your account number ready. The system will ask for it first, and you cannot proceed without it. If you don't have your bill handy, look up your account number on the CPS Energy website before you call, or have a representative look it up for you.
Another mistake is paying the wrong amount. Check your bill to see what you owe—it's listed as "Amount Due" near the top. If you're unsure whether you owe a full month's bill or a partial amount, ask the representative. Overpaying is not harmful (the extra becomes a credit on your account), but underpaying may result in a late fee or service interruption if your account falls behind.
Do not hang up before you receive your confirmation number. Write it down or take a photo of it. If there's ever a dispute about whether your payment went through, the confirmation number is proof that you paid.
When to use phone payment instead of other methods
Phone payment is fastest if you need to pay immediately and don't have time to set up online payment or mail a check. It's also useful if you don't have internet access or prefer not to create an online account. The 24/7 automated line means you can pay at midnight on a Sunday if you need to.
If you pay regularly, setting up automatic payments online or through the CPS Energy app may save you time in the long run. You can schedule payments in advance and never have to think about it. However, if you pay irregularly or want to control the exact date and amount each time, phone payment gives you that flexibility.
What to do if your payment doesn't go through
If the automated system rejects your payment, it will tell you why—usually because the card or bank account information was entered incorrectly, the card is expired, or there are insufficient funds. Correct the information and try again, or call a representative for help.
If you received a confirmation number but the payment doesn't appear on your bill within two business days, contact CPS Energy customer service at 1-210-353-2222. Have your confirmation number ready. A representative can look up the payment in the system and tell you its status. Payments occasionally take longer if they were made late in the day or over a weekend, but two business days is the normal window.
Other ways to pay your CPS Energy bill
Beyond phone payment, CPS Energy offers several other options. You can pay online through the CPS Energy website or mobile app using a debit card, credit card, or bank account. You can mail a check to the address on your bill. You can pay in person at a CPS Energy office or at authorized payment locations around San Antonio.
You can also set up automatic payments so your bill is paid from your bank account on the same date each month. This removes the need to remember to pay and ensures you never miss a due date. To set up automatic payments, log into your CPS Energy account online or call customer service.
Frequently Asked Questions
Is there a fee for paying by phone?
No fee for debit card or bank account payments. Credit card payments may incur a fee from your card issuer or a third-party processor, not from CPS Energy. The system tells you the fee before you confirm, so you can choose whether to proceed.
Can I pay someone else's CPS Energy bill by phone?
Yes, if you have their account number. The system doesn't verify that you are the account holder—it only needs the account number and payment information. However, if you're paying a bill for someone else regularly, they should consider adding you as an authorized user on their account.
What if I want to set up a payment plan instead of paying the full amount now?
Phone payment is for immediate, full payments only. If you cannot pay your full bill, call customer service at 1-210-353-2222 during business hours to discuss a payment arrangement. Representatives can work with you on a plan that fits your situation.
How long does it take for a phone payment to show up on my bill?
Debit and credit card payments post within one business day. Bank account payments (ACH) also typically post within one business day. You'll receive a confirmation number immediately when you hang up, which proves the payment was made even if it hasn't appeared on your bill yet.
Can I cancel a payment after I've made it by phone?
Once you receive a confirmation number, the payment is processed and cannot be canceled. If you made a mistake—such as paying twice or paying the wrong amount—contact CPS Energy customer service immediately. They may be able to issue a refund or credit, depending on the situation.
