Pay your Mon Power bill through FirstEnergy's website, by phone, or by mail
Mon Power (Monongahela Power Company) is a FirstEnergy subsidiary that serves parts of West Virginia. You can pay your bill in several ways: online through the FirstEnergy website, by automatic bank draft, by phone, or by mailing a check. The fastest and most convenient method is online payment, which posts to your account within one business day.
Each payment method has different timing and requirements. If you pay online or by phone, have your account number ready — it appears on your bill statement. If you mail a payment, allow 7 to 10 business days for it to reach Mon Power and post to your account. Paying late can result in a late fee and may affect your service, so knowing your bill due date is essential.

Pay online through FirstEnergy's website
Visit the FirstEnergy website and log into your account using your username and password. If you do not have an online account, you can create one by entering your account number and service address. Once logged in, select the "Pay My Bill" option and enter the amount you want to pay.
You can pay using a debit card, credit card, or bank account. Credit card payments may carry a convenience fee, while bank account payments typically do not. After you submit your payment, you will receive a confirmation number. Keep this number for your records. The payment will post to your account within one business day, though it may take longer if you pay after business hours or on a weekend.
Set up automatic bank draft to avoid missed payments
Automatic bank draft withdraws your bill amount directly from your checking or savings account on a date you choose — usually around your bill due date. This method removes the risk of forgetting to pay and helps you avoid late fees. You can set it up online through your FirstEnergy account or by calling Mon Power customer service.
To enroll online, log into your account, go to "Billing & Payment," and select "Enroll in AutoPay." You will need to provide your bank account number and routing number. You can change or cancel automatic draft at any time through your account settings. If you cancel, you will need to resume paying by another method.
Pay by phone with Mon Power customer service
Call Mon Power at the number on your bill to pay by phone. Have your account number and payment method ready. You can pay using a debit card, credit card, or bank account. Phone payments may include a convenience fee if you use a credit card, but bank account payments typically do not.
Phone payments are processed immediately, and you will receive a confirmation number. Keep this number in case you need to reference the payment later. If you call after business hours, you can use the automated phone system to make a payment without speaking to a representative.
Mail a check or money order to Mon Power
If you prefer to pay by mail, write a check or money order and include your account number on the payment. The mailing address is printed on your bill statement — do not send payment to a different address. Mail your payment at least 10 business days before your due date to ensure it arrives and posts on time.
Keep a copy of your cancelled check or a photo of your money order receipt for your records. Mailed payments can take 7 to 10 business days to process, and delays in mail delivery can push this timeline longer. If your payment does not post by your due date, contact Mon Power to confirm they received it.
Understand late fees and service disconnection
If your payment does not arrive by the due date shown on your bill, Mon Power will charge a late fee. The amount varies but is listed in your service agreement. A late fee is added to your next bill. If you remain unpaid for 30 days or more past the due date, Mon Power may disconnect your service without further notice.
If you cannot pay your full bill by the due date, contact Mon Power immediately to discuss a payment plan or other options. Some customers may be may be able to access for assistance programs, and speaking with a representative early gives you more options than waiting until service is at risk.
What to do if your payment does not post
If you paid online or by phone and your account still shows an outstanding balance after one business day, log into your FirstEnergy account and check the payment status. The confirmation number from your payment will help you track it. If the payment appears to have failed, you may need to resubmit it.
If you mailed a check and it has been more than 10 business days since you sent it, contact Mon Power with your check number and the date you mailed it. They can search their records to confirm receipt. If the check was lost in the mail, you may need to stop payment on the original check and send a new one.
