A special message from our President and CEO, Joe Purington

When I was growing up in Jay, Maine, my dad worked at the mill and my mom in the school cafeteria. These were steady jobs in our community that could support a family and keep oil in the tank, gas in our car and food on the table. But even then, there were times when our neighbors struggled to stay warm in winter.

We know this winter may be tough for many Maine families. We have seen the price of everything—from home heating oil to groceries—go through the roof. Electricity supply is not immune to cost increases, especially as New England must import natural gas to generate electricity and heat homes. This makes it more expensive.

Recently, the Maine Public Utilities Commission announced that the Standard Offer price for electricity supply will be going up by 49% or almost $32 a month for our average residential customer in 2023.

I want to let you know that CMP only delivers the electricity you use and does not influence or control the supply price even though we are required to include and collect the cost in our monthly bills. You will find your supply charges on a separate supplier page of your bill.

We can offer you ways to better understand your energy use and perhaps better manage your electricity costs. At you can find free tools for energy management, budget and payment plans for your bills, information on how you can choose a different energy supplier and information on other sources of assistance. In addition, you can call us at 800.750.4000, Monday through Friday, from 7:30am - 6pm.

As someone born and raised in rural Maine, I know winters can be hard and long, but we will get through it—we always do. And here at CMP, we will be here to help in any way we can.

President and CEO, Central Maine Power Company
