What is CMP’s eBill Service?
eBill is a FREE service from Central Maine Power that lets you view, pay and store up to 36 months of your CMP bills securely online. To learn more, view our eBill demo. ^top

How do I sign up for eBill?
Once you’ve created your online profile, you can enroll your account(s) in eBill by logging in and clicking the Receive my bill online button. From there, you can select the accounts you want to enroll.

Getting Started
To sign up for eBill, you must:

  • Be a current customer
  • Create an online profile
  • Have a valid e-mail address
  • Have access to a computer with Internet connection

For step-by-step instructions on how to create your online profile and enroll in eBill, visit our eBill demo.

If you are a Summary Billing customer (multiple accounts on one bill), have a monthly bill that was $100,000 or more in any of the previous twelve months, or you participate in net energy billing, you are unable to enroll in eBill at this time. ^top

When will I be able to access my first eBill?
Once you’ve enrolled your account(s) and agreed to the program terms, you will immediately have access to any bills associated with your account. Online billing will follow your normal billing cycle. ^top

Will I still receive a paper bill if I enroll in eBill?
eBill is a paperless billing service so you will no longer receive a paper bill in the mail. You will be able to view up to 36 months of bills online and file them for your records. You also have the option to print copies of your bill. ^top

How will I know I have a new eBill?
You will receive an e-mail notification when you have a new eBill available to view and pay. You can also set up payment reminders to receive another e-mail notification prior to your due date. ^top

Can I still pay on my account if my eBill is not available yet?
Yes, you can make an online payment at any time. You can use the link on the CMP Homepage, or there is a link available at the bottom of your eBill Homepage. ^top

Can I stay on AutoPay if I want to enroll in eBill?
Yes, you can enjoy all the convenience of eBill and AutoPay! You will need to set up automatic payments again through eBill. For step-by-step instructions, visit our eBill demo.

To avoid multiple automatic payments, we will remove your account from AutoPay and cancel all scheduled payments. Please make an online payment for your current bill and your new automatic payment will begin with your next bill. ^top

Is it possible to enroll in CMP’s eBill and other online bill websites like CheckFree?
Yes, you can enroll in multiple bill payment websites and view your bill through each. However, we suggest that you choose one site for making payments to your CMP account as you could accidentally pay your bill twice. ^top

Can I cancel eBill at any time?
Yes, you must log on to your online account and choose Change eBill Accounts to de-select the accounts you want to de-enroll. You will begin receiving paper bills again with your next billing cycle.

Please note: Any scheduled online payments and automatic payments will be canceled when you de-enroll from eBill. ^top

Payment Options

Can I have my bill paid automatically each month?
When you enroll in our AutoPay program, your payment will be automatically deducted from your checking or savings account on time, each month. If you are already enrolled in eBill, log in to your account and add an automatic payment. If you are not an eBill customer, click here to enroll.

I just enrolled in AutoPay. When will my automatic payments begin?
Your automatic payment will begin with your next bill. Or, if you chose a future start date, it will begin with next billing cycle after date you selected. Please make an online payment for any bills prior to the start of your automatic payment.

Why can’t I set up AutoPay for a specific date?
You can choose for your automatic payment to be deducted between 4 and 23 days before your due date. This ensures that your payment is posted to your account before your next billing.

Can I pay the same amount each month?
Yes, our SimplePay Plan lets you make a level monthly payment based on your electricity usage over the past year. You’ll get a bill for the same amount each month, so you’ll know ahead of time what your payment will be.

We’ll review your account every six months to make sure your payment amount is still accurate based on your actual usage and recalculate your payment if necessary. Click here to learn more and enroll.

Does it cost anything to pay my bill online?

How far in advance of the due date should I schedule my online payment?
Schedule your payments at least four business days before the actual due date. For example, if you have a bill due on the 15th of the month, schedule the payment date for the 11th or earlier. This allows enough time for us to receive the payment and credit your account by the due date. ^top

Can I make a payment for more or less than my current amount due?
You have the option to type in the amount of the payment you wish to make. Please note that an unpaid remaining balance may be subject to late fees. ^top

Can I make more than one payment per month?
Yes, you can submit multiple payments for a single account. ^top

How do I change the amount or date of a scheduled payment?
If your payment has a status of “Scheduled” you may adjust the dollar amount of your payment until 5:00 pm EST of the business day that the payment is scheduled to be submitted for processing.

You may adjust the payment date at any time. However, if your payment has already been submitted for processing, you will no longer be able to change the date.

Payments in any payment status other than “Scheduled” cannot be adjusted or cancelled online. If you have concerns about your payment, please call us at 1.800.750.4000 (residential customers) or 1.800.565.3181 (commercial customers). ^top


How can I confirm that a payment has been made?
When you log in to your online account, choose Payment History under Manage Your Account. You will see your billing and payment history for the past 24 months. ^top

When is the money for a payment taken from my bank account?
CMP submits the payment to your financial institution for processing on the scheduled payment date. ^top

I made a payment at a Payment Agency today. Why doesn’t it appear on my payment history?
Payments made through an authorized Payment Agency are not posted until the next business day. However, if you are in threat of disconnection, we are notified of your payment immediately. Please note that processing may take longer if an unauthorized Payment Agency accepted your payment. ^top

How secure is my billing, payment and personal information?
We use several methods to ensure that your information is secure.

  • Username and Password: Your username and password are unique identifiers that only you know. Keep them private so others can’t sign on to access your account information.
  • Secure Pages: All online payment webpages as well as any page that requires you to log in to access is secure. This can be verified by the URL beginning with “https”.
  • Encryption: CMP uses 128-bit encryption (data coding) to make your information unreadable as it passes over the Internet.
  • Fraud detection service: If you are making an online payment, you are asked to enter five random digits before submitting your payment in order to verify that you are not a computer. ^top

Can I pay other household bills at the CMP website?
Our online billing and payment services are for CMP bills only. ^top
