How to pay your Delmarva Power bill
Delmarva Power offers three main ways to pay: online through their website, by phone, or by mailing a check. The fastest route is online through your account at delmarva.com, where payment posts the same day if you pay before 5 p.m. Eastern time on a business day. Phone payments go through when ready but carry a fee, and mail takes 7 to 10 business days to reach their lockbox and post to your account.
You will need your account number to pay any way except online, where you can log in with your username and password instead. Your account number appears on your bill in the upper right corner and is usually 10 digits long. If you do not have your bill handy, you can look up your account number on the Delmarva Power website after you log in.
Key Takeaways
- Online payment through delmarva.com is free and posts the same business day if submitted before 5 p.m. Eastern time.
- Phone payments are processed when ready but charge a fee; call 1-800-375-3500 to pay this way.
- Mailing a check takes 7 to 10 business days to post, so send it at least two weeks before your due date to avoid a late fee.
- You can set up automatic payments from your bank account through the Delmarva Power website to avoid missing a due date.
- Late fees explore if your payment does not post by the due date shown on your bill, regardless of when you sent it.
Paying online through your Delmarva Power account
Log in to your account at delmarva.com using your username and password. If you do not have an online account yet, you can create one by clicking "Register" on the login page and entering your account number, email address, and a password. The registration process takes about five minutes and lets you view your bill, see your payment history, and pay when ready.
Once you are logged in, look for "Pay My Bill" or a similar button on your account dashboard. Enter the amount you want to pay — you can pay the full balance, a partial amount, or set up a one-time payment for a future date. Choose your payment method: bank account (ACH transfer) or debit or credit card. Bank account payments are free; card payments charge a fee that Delmarva Power will show you before you confirm. Review the payment details and click to complete the transaction.
Payments submitted before 5 p.m. Eastern time on a business day post the same day. Payments submitted after 5 p.m. or on weekends and holidays post the next business day. You will receive a confirmation number when ready after payment; save this for your records.
Paying by phone
Call Delmarva Power's payment line at 1-800-375-3500. Have your account number ready, or the phone number associated with your account. An automated system will walk you through the payment process and ask you to enter your account number using your phone keypad, then the amount you want to pay.
You will be asked to provide a debit or credit card number, or to authorize a bank account withdrawal. The system will confirm the amount and the date the payment will post. Phone payments are processed when ready, but a convenience fee applies — Delmarva Power will disclose the exact fee before you authorize the payment. If you need to speak to a representative instead of using the automated system, stay on the line after the greeting and ask to be transferred.
Paying by mail
Write a check payable to Delmarva Power and include your account number on the check itself. Mail it to the address shown on your bill — this is usually a lockbox address in Delaware or Maryland, not a local office. Include your bill stub if possible, as it helps the payment post faster.
Mail takes 7 to 10 business days to arrive and post to your account. To avoid a late fee, mail your payment at least two weeks before your due date. If your due date is approaching and you have not yet mailed a check, use online or phone payment instead. Late fees are assessed based on when the payment posts to your account, not when you mailed it.
Setting up automatic payments
Automatic payments remove the risk of missing a due date. Log in to your Delmarva Power account online and look for "Autopay," "Automatic Payment," or "Recurring Payment" in the account settings or billing section. Choose whether you want to pay the full bill amount each month or a set dollar amount, and select the date you want the payment to come out of your account.
You can authorize automatic payments from your bank account (free) or a debit or credit card (fee applies). Delmarva Power will send you a confirmation email with the details, and you can cancel or change the payment amount or date anytime by logging back into your account. If you cancel automatic payments, you will need to pay manually going forward.
What to do if your payment is late
A late fee is added to your bill if your payment does not post by the due date. The amount of the late fee varies but is typically a percentage of your bill or a flat fee — check your bill or contact Delmarva Power to learn the exact amount. Late fees do not prevent you from paying; you can still pay your full balance plus the late fee at any time.
If you are having trouble paying your bill, contact Delmarva Power at 1-800-375-3500 to discuss payment plans or other options. They may be able to extend your due date or set up a plan to spread your payment over several months. Do not ignore a bill; unpaid accounts can result in service disconnection after a certain period of non-payment.
