Central Maine Power's main customer service number

Central Maine Power (CMP) operates the electric grid across most of Maine. Their main customer service line is 1-800-696-1000. This number handles billing questions, outage reports, account changes, and general inquiries. The line is staffed Monday through Friday, 7:30 a.m. to 5 p.m. Eastern Time.

When you call, have your account number ready — it appears on your bill and speeds up the process. If you are calling about an outage, CMP can tell you whether the power is out in your area and when service is expected to return. For outages, you can also report online at cmpco.com or through their mobile app.

Outside business hours, an automated system takes outage reports and handles some account questions. The system can also direct you to emergency services if you have a downed power line or other safety hazard.

What to expect when you call

When you reach CMP's customer service line, you will hear a menu with options. Press 1 for billing and account questions, 2 for outages, or follow the prompts for other needs. The wait time varies by time of day and season — it is typically shorter on weekday mornings and longer on Monday mornings or during winter storms.

If you are calling about a bill, have the bill itself in front of you. The representative can explain charges, discuss payment plans, or update your contact information. If you are behind on payments, CMP has programs that may help — the representative can explain what is available based on your situation.

For outages, the system or representative will ask for your address and phone number to confirm the outage and give you an estimated restoration time. If you report a downed power line or other hazard, stay on the line and follow the representative's instructions.

Other ways to reach Central Maine Power

Beyond the phone, CMP offers several other contact methods. You can visit their website at cmpco.com to pay a bill, report an outage, view your account, or start a chat with a representative. The website also has a section for frequently asked questions and links to payment information programs.

The CMP mobile app (available on iOS and Android) lets you report outages, check outage status in your area, pay your bill, and view your account history. Many customers find the app faster than calling during peak times.

If you have a billing dispute or a complaint that phone support did not resolve, you can file a complaint with the Public Utilities Commission of Maine. Their contact information is available at maine.gov/puc.

Outage reporting and emergency situations

CMP's outage line (still 1-800-696-1000, option 2) is staffed 24 hours a day during outages. If the power goes out, call to report it and get an estimated time for restoration. The system will ask for your address and phone number and may ask whether you have anyone in your home who depends on electricity for medical equipment.

If you see a downed power line, do not touch it or go near it. Call 911 first, then call CMP at 1-800-696-1000. Stay at least 30 feet away from the line and warn others to do the same. If the line is near water or a vehicle, call 911 when ready.

During major storms, CMP's lines can be overwhelmed. If you cannot reach them by phone, use the website or app to report the outage. Both methods feed into the same system, and you will receive updates about restoration time through the method you used to report.

Billing and payment questions

When you call about your bill, have your account number and the bill itself ready. CMP representatives can explain any charge, discuss your usage, or set up a payment arrangement if you cannot pay the full amount right away. They can also update your mailing address, email, or phone number on file.

If your bill is higher than usual, the representative can tell you whether it is due to increased usage, a rate change, or a billing cycle difference. They can also discuss energy-saving steps or programs that may lower your bill.

CMP offers budget billing, which spreads your annual costs evenly across 12 months so your bill is more predictable. You can ask about this when you call, or sign up through the website.

Service area and account setup

CMP serves central, southern, and western Maine. If you are moving into CMP's service area, you can start service by calling 1-800-696-1000 or through the website. You will need to provide your name, address, and move-in date. CMP will schedule a meter read and send you information about your first bill.

If you are moving out of CMP's service area or ending service at your current address, call to schedule a final meter read. CMP will send a final bill based on your usage through the end date you provide.

If you are not sure whether CMP serves your address, enter your address on their website or call the main number. They can tell you when ready whether you are in their service area.
