The payment method you select will be used to pay your bills. You can update or change your payment method at any time.

If you’ve selected Credit Card as your payment method, you can enable Autopay to automatically pay your bill balance each month when it’s posted. Autopay is not available for other payment methods (e.g., Check or Bank Account).

Regardless of your payment method, you’ll still receive an email notification whenever a new bill is posted to your account.

If you turn on Dual Billing, you’ll continue to receive and pay your monthly bill directly from Central Maine Power (CMP), and you’ll also receive a separate bill from Maine Community Power Cooperative for your community solar subscription.

If you turn off Dual Billing, you’ll receive a combined bill from Maine Community Power Cooperative that includes both:

• The cost of your community solar subscription, and
• The remaining balance of your CMP bill

In this case, you can ignore your CMP bill—we’ll pay CMP on your behalf.

Even with Dual Billing turned off, you’ll still receive your CMP bill electronically or by mail, depending on the preferences set in your CMP account.

To turn Dual Billing on/off:

1. Select “Billing” from the portal menu.
2. Scroll down to the “Billing Options” section.
3. Click the "Dual Billing?" toggle to enable/disable it.

You can choose to receive a paper copy of your Maine Community Power Cooperative bill for an additional charge of $0.30/month. To receive a paper bill:

1. Select “Billing” from the portal menu.
2. Scroll down to the “Billing Options” section.
3. Click the "Paper Bill" toggle to enable it.

If you receive a paper bill, you’ll still get an email notification when a new bill is posted to your account. You can also pay your bill online at any time, if you prefer.

To assign members to our solar projects, we need to connect to your Central Maine Power (CMP) account. This connection allows us to:

• Retrieve your monthly utility bill data
• Analyze your electricity usage history
• Assign your account(s) to the right project
• Send you accurate, timely bills

We use a secure third-party service called Bayou Energy to connect to your utility account.

If you cannot find your utility account credentials, go to https://www.cmpco.com/c/portal/login and use the "Forgot Password?" or "Forgot ID?" options to recover your credentials. You can also contact Central Maine Power customer support for assistance. 

If you do not have a Central Maine Power online account, you can register for online account access at https://portal.cmpco.com/registration/select-account. You will need:

• Your Central Maine Power account number(s) from your monthly bill
• The Zip code of your service address(es)

If you need any help you can contact Central Maine Power customer support for assistance.

You can view your project assignment by selecting "Solar Project" from the portal menu. If you have not yet been assigned to a project you'll see a message that says "Your Solar Project is Coming Soon".

We assign our members to projects based on several factors. We prioritize low- to moderate-income households and residential members who do not have onsite solar or other forms of self-generation. We keep our members updated on our project development process in regular email newsletters so that you know when our next projects are coming online. If you have any questions, contact us.

After you connect your utility account(s):

• We’ll review your account and determine the best project placement.
• If any action is needed from you, we’ll let you know.
• You’ll be notified approximately 2 months in advance of your assignment to a project.
• Your electric utility billing period may shift about 1 month prior to your project assignment to align with other accounts on the same project.
• Solar credits will begin appearing on your bill once your assignment is active.

We’ll keep you informed every step of the way.
