Where to pay your Central Maine Power bill

Central Maine Power (CMP) gives you four main ways to pay: online through their website, by phone, by mail, or in person at a payment location. The fastest and most convenient is online at centralmaine.com — you can pay any time without waiting for business hours, and the payment posts the same day if you submit it before 5 p.m. Eastern time on a business day.

If you prefer to pay by phone, call CMP's automated payment line at 1-800-696-1000. You'll need your account number (on your bill) and a debit card or checking account. Payments made by phone before 5 p.m. Eastern also post the same business day.

For mail payments, send your check or money order to the address printed on your bill — usually Central Maine Power, P.O. Box 4350, Augusta, ME 04330. Mail payments take 7 to 10 business days to reach CMP and post to your account, so plan ahead if your due date is coming up soon.

Key Takeaways

  • Online and phone payments through CMP post the same business day if submitted before 5 p.m. Eastern, while mail payments take 7 to 10 days.
  • You can set up automatic payments from your bank account or debit card to avoid late fees and missed due dates.
  • CMP does not charge a fee for online or phone payments made directly through their website or automated line.
  • If you're having trouble paying, contact CMP about budget billing or hardship programs before your bill becomes overdue.

Setting up automatic payments to avoid missed due dates

The easiest way to never miss a payment is to set up automatic recurring payments through CMP's website. Log into your account, go to the payment section, and choose "Autopay" or "Recurring Payment." You can have CMP withdraw the full bill amount or a fixed amount each month on a date you choose.

Automatic payments come from your checking account or debit card and post the same day they're processed. You can change or cancel the arrangement anytime through your online account, and CMP will send you a confirmation email each time a payment is made.

If you don't have online access or prefer not to set it up yourself, call CMP at 1-800-696-1000 and ask a representative to enroll you in automatic payments over the phone. You'll need your bank account or debit card information ready.

Understanding your bill due date and late payment fees

Your bill due date appears on the front of your statement, usually 20 to 25 days after the bill is issued. If you don't pay by that date, CMP charges a late fee — the amount varies but is typically a percentage of your unpaid balance or a flat fee, whichever is greater. The exact late fee is listed in your bill's terms and conditions or on CMP's website.

Payments are considered on time if they're received (not just mailed) by the due date. For online and phone payments, that means submitting before 5 p.m. Eastern. For mail, the postmark date doesn't matter — only the date CMP receives it. If you're cutting it close, use online or phone payment instead.

If your payment is more than 30 days late, CMP may disconnect your service. You'll receive a disconnection notice before that happens, usually giving you at least 10 days to pay or contact CMP about a payment plan.

What to do if you can't pay your full bill on time

If you're struggling to pay, contact CMP before your bill becomes overdue. Call 1-800-696-1000 and explain your situation. CMP offers budget billing, which spreads your annual energy costs into equal monthly payments so you're not hit with a large bill in winter or summer. You still pay the full amount over the year, but the payments are more predictable.

CMP also has hardship programs for customers facing financial difficulty. Depending on your income and household size, you may be referred to community action agencies or other local programs that can help with energy bills. These programs are separate from CMP but CMP can connect you to them.

If you receive a disconnection notice, you have options. You can request a payment extension (usually 10 to 15 days), set up a payment plan to pay the overdue amount in installments, or ask about emergency assistance programs. The key is to call CMP as soon as you know you'll be late — waiting until after disconnection makes it harder to restore service.

Reading your CMP bill to find the amount due

Your bill has several sections, but the amount you owe is clearly marked near the top or bottom of the first page, usually labeled "Amount Due" or "Total Amount Due." This is the number you need to pay by the due date shown on the same page.

Below that you'll see a breakdown of charges: the cost of electricity you used (based on your meter reading), any taxes, and fees. If you're on budget billing, your monthly payment will be the same each month even if your actual usage varies. If you're on a standard plan, the amount due changes month to month based on how much electricity you used.

Your bill also shows your account number, service address, and the meter reading date. Keep this information handy when you pay online or by phone — you'll need your account number to process the payment.

Paying online through your CMP account

To pay online, go to centralmaine.com and click "Pay My Bill" or "Login." If you don't have an online account yet, you can create one using your account number (from your bill) and service address. Once logged in, you'll see your current bill amount and due date.

Click "Make a Payment" and choose whether to pay the full amount due or a different amount. Enter your payment method (debit card or bank account), review the details, and submit. You'll get a confirmation number immediately — save this for your records. The payment posts the same business day if submitted before 5 p.m. Eastern.

CMP does not charge a fee for online payments made directly through their website. Some third-party payment processors may charge a fee, but CMP's own system is free. Always pay through centralmaine.com to avoid unnecessary charges.

Frequently Asked Questions

Can I pay my CMP bill with a credit card?

CMP's website and phone line accept debit cards and bank account transfers, but not credit cards directly. If you want to use a credit card, you can pay through a third-party payment processor, but they typically charge a fee of 2 to 3 percent. For most people, paying with a debit card or bank account is cheaper and faster.

What happens if I pay after the due date?

CMP charges a late fee if payment is received after the due date. The fee amount depends on your bill balance. If you're more than 30 days late, CMP may disconnect your service after sending a disconnection notice. Contact CMP immediately if you know you'll be late — they can discuss payment plans or extensions.

How do I know if my payment went through?

For online and phone payments, you'll receive a confirmation number right away. Log into your account a few hours later to see the payment reflected in your account balance. For mail payments, allow 7 to 10 business days and check your account online or wait for your next bill to confirm it posted.

Can I set up automatic payments for just part of my bill?

Yes. When you set up autopay through CMP's website, you can choose to pay the full bill amount each month or a fixed amount of your choosing. If you choose a fixed amount less than your bill, you'll still owe the difference by the due date, but autopay covers part of it automatically.

What if I need to dispute a charge on my bill?

Contact CMP before paying if you think your bill is wrong. Call 1-800-696-1000 and explain the issue. CMP can review your meter reading and usage. While the dispute is being investigated, you should still pay the undisputed portion by the due date to avoid late fees, even if you're disputing part of the bill.
