Central Maine Power (CMP), a subsidiary of Avangrid, Inc., is urging customers to stay vigilant as scammers continue to target Maine residents through phone calls, emails, and even door‑to‑door impersonation. These schemes often involve aggressive tactics and requests for personal or financial information, falsely presented as urgent matters. 

“Scammers are becoming more sophisticated, and the best defense is staying alert and taking steps to verify who you’re dealing with,” said Mark Morisette, Vice President of Customer Service for Central Maine Power, in a news release. “If something feels off, whether it’s a phone call, a knock at the door, or an unexpected message, trust your instincts and contact CMP directly at 800-750-4000. We will never pressure you to provide personal information or demand payment through unusual methods. We encourage customers to contact us anytime they have a doubt or need assurance.” 

To help customers identify legitimate CMP employees and protect their personal information, CMP offers the following guidance: 

How to Verify a CMP Employee or Communication 

• Customers can always call CMP’s customer service line (1‑800‑750‑4000) to confirm whether there is an issue with their account or to verify the identity of someone claiming to represent the company.
• CMP employees will always carry an official ID badge and travel in CMP‑branded vehicles. 

CMP Will Never:

• Ask to see your bill or private account information.
• Send employees inside your home to use your computer or personal devices.
• Take photos of your electric bill.
• Visit your home to offer discounts, special programs, or sign‑ups.
• Ask for payment through prepaid debit cards or any other non‑refundable method. 

Customers should be especially cautious of several ongoing scam tactics. These include disconnection threats, where impostors claim a past‑due balance and demand immediate payment through prepaid debit cards; meter‑payment schemes urging cash or prepaid card purchases for fake meter upgrades; and fraudulent claims that a recent payment failed due to a “system glitch,” followed by requests for sensitive banking information. 

If customers suspect suspicious activity, they should take immediate steps to protect themselves. Anyone who believes they’ve been targeted or feels threatened should report the incident to local law enforcement and the Federal Trade Commission. CMP will never ask customers to purchase prepaid cards, and representatives are available to discuss legitimate payment options or assist with account concerns. Anyone unsure of a caller’s identity should hang up and contact CMP directly and should never share personal or account information with an unverified source. 

Here is more information from the Maine Attorney General’s office on how you can protect yourself from scams.
