A special message from our President and CEO, Joe Purington

At Central Maine Power Company, we are proud to have knowledgeable, well trained customer service representatives who can talk to you about the many options available if you are facing challenges in paying your electricity bill.

CMP does not supply electricity and we do not control the cost of supply, even though the charge appears on your CMP bill. The Maine Public Utilities Commission has announced a sizeable increase in the cost of the Standard Offer Provider supply cost, which took effect January 1, 2022. You can see your supplier and their charges on page 3 of your bill.

We can offer you free tools to understand and manage your energy usage so you can make choices in your home and perhaps reduce your usage and cost. We can also offer you guidance about payment plans and sources of assistance if your bill will be difficult to pay. We ask that you call us so we can take the time to explain these options and help you plan. You can reach us at 800.750.4000, Monday through Friday, from 7:30am - 6pm.

As a native Mainer I know how long the Maine winters can be. As the President and CEO of CMP I’d like to help you find a way to make the season less challenging.

Sincerely,

Joe Purington
President and CEO, Central Maine Power Company
