How to Pay Your Bill Through SDTTC.com

What SDTTC.com is and how to use it

SDTTC.com is the online bill pay portal for San Diego Gas & Electric (SDG&E) customers. It lets you view your bill, make one-time payments, set up automatic payments, and manage your account from any device with internet access. You do not need to call SDG&E or visit a payment center to pay your bill — you can do it from home in minutes.

The site is run by SDG&E directly, so payments go straight to your utility account. You will need your SDG&E account number and a way to pay — a bank account for ACH transfers, a debit card, or a credit card. Some payment methods may charge a fee; SDG&E's website shows which ones do before you confirm.

Key Takeaways

• SDTTC.com is SDG&E's official bill pay site, where you can pay online without calling or visiting an office.
• You need your SDG&E account number to log in or pay as a guest, and a bank account or debit card to complete the payment.
• One-time payments usually post within one to two business days, while automatic payments deduct on the date you choose each month.
• If you forget your login, use the "Forgot Password" link on the home page to reset it by email or phone.
• Payments made after 5 p.m. Pacific Time may not post until the next business day.

How to log in or pay as a guest

If you have an SDG&E online account, go to SDTTC.com and enter your username and password. If you do not have an account yet, you can still pay without logging in by selecting the guest payment option and entering your account number instead.

To find your account number, look at a recent SDG&E bill — it appears near the top, usually next to your name. If you do not have a bill handy, you can call SDG&E customer service at 1-800-411-7343 to confirm it. Once you enter your account number on SDTTC.com, the site will show your current balance and due date.

Making a one-time payment

After logging in or entering your account number as a guest, select "Make a Payment" or the equivalent option on the home page. The site will display your current bill amount and due date. You can pay the full amount, a partial amount, or a different amount if you choose.

Choose your payment method: ACH transfer from a bank account (usually free), debit card, or credit card. Enter the payment details and review the amount and date before confirming. The site will show you a confirmation number when ready — save or print this for your records. One-time payments typically post within one to two business days, though payments made after 5 p.m. Pacific Time may not process until the next business day.

Setting up automatic payments

Automatic payments let you choose a date each month when SDG&E will deduct your bill amount from your bank account or card. This removes the need to remember to pay each month. To set this up, log in to your account, find the "Automatic Payments" or "Recurring Payments" section, and select "Enroll" or "Add."

You will choose a payment date (usually between the 1st and the 28th of each month), your payment method, and whether to pay the full bill or a set amount. SDG&E will deduct the payment on that date every month until you cancel. You can change the date or amount anytime by logging back in, and you can cancel automatic payments at any time without penalty.

What to do if your payment does not go through

If a payment fails, SDTTC.com will usually show an error message right away — often because the bank account or card information was entered incorrectly, the card has expired, or there are not enough funds. Check the error message, correct the information, and try again with a different payment method if needed.

If a payment was deducted from your account but does not appear on your SDG&E bill within two business days, contact SDG&E customer service at 1-800-411-7343. Have your confirmation number ready. SDG&E can trace the payment and confirm whether it posted or needs to be resubmitted.

Resetting your password or account access

If you forget your SDTTC.com password, go to the home page and select "Forgot Password" or "Forgot Username." The site will ask for your account number and email address or phone number on file. SDG&E will send you a reset link by email or a code by text message, depending on which you choose.

Click the link or enter the code to create a new password. If you do not receive the reset email or text within a few minutes, check your spam folder or try the other contact method. If you still cannot reset your password, call SDG&E customer service at 1-800-411-7343 and they can help you regain access.

Frequently Asked Questions

Is there a fee to pay my bill on SDTTC.com?

ACH transfers from a bank account are free. Credit card and debit card payments may have a fee — SDTTC.com shows the fee amount before you confirm the payment, so you can choose whether to proceed or use a different method.

How long does it take for a payment to show up on my bill?

One-time payments usually post within one to two business days. Payments made after 5 p.m. Pacific Time may not process until the next business day. Automatic payments deduct on the date you choose and post the same day or the next business day.

Can I pay someone else's SDG&E bill through SDTTC.com?

You can pay a bill if you have the account number, but the payment will go to that account. If you are not the account holder, contact SDG&E customer service to confirm whether you can authorize payments on that account, as some accounts require the primary account holder's permission.

What if I want to stop automatic payments?

Log in to SDTTC.com, go to the "Automatic Payments" section, and select "Cancel" or "Remove." The cancellation takes effect when ready, and no further payments will be deducted. You can set up automatic payments again anytime.

Can I see my payment history on SDTTC.com?

Yes. Log in to your account and look for "Payment History," "Transaction History," or a similar section. It will show all payments you have made, the dates they posted, and the amounts. You can usually read or print this history for your records.
