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 cmpco.com 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.

Sincerely,

Joe Purington
President and CEO, Central Maine Power Company

How Are Prices Determined?

Who is responsible?

The prices, practices, and level of profitability are regulated primarily by the Maine Public Utilities Commission (PUC). The PUC was created by Maine law and began work in 1914. Its three commissioners were nominated by the Governor and confirmed by the Maine Senate.

The Commissioners are assisted by legal, technical, financial and consumer-assistance staff. PUC proceedings use court-like standards of evidence, procedure and decisions that allow opportunities for interested citizens or groups to participate as formal interveners in the process.

Maine Public Service Commission

Office location: 101 Second St. Hallowell, ME 04347

Mailing address: 18 State House Station Augusta ME 04333-0018

Telephone: 207.287.3831

Website: www.maine.gov/mpuc

Our transmission prices are determined by the Federal Energy Regulatory Commission (FERC).

How does the PUC set delivery prices?

There are five components that make up a delivery price. The PUC separately sets the five pieces that make up our delivery prices.

The distribution piece covers the costs of local power lines, meter readers, and bucket trucks. For most customers, this makes up the majority of their delivery price.
The transmission piece covers the costs of large power lines and substations and is regulated by the Federal Energy Regulatory Commission.
The stranded cost piece covers costs of power contracts with small hydro, biomass, waste-burning and nuclear plants that were left over from before we became a delivery-only utility (we ceased selling energy when that part of the electric business was de-regulated in March 2000). Stranded costs continue to decline.
The conservation assessment piece funds energy efficiency initiatives.
The Electricity Lifeline Program (ELP) provides assistance to residential customers who qualify for the Home Energy Assistance Program.

What options do I have to purchase my electricity supply?
Central Maine Power provides transmission and delivery of electricity. CMP is not a supplier and does not generate or sell electricity. The Maine Public Utility Commission chooses the Standard Offer (default) supplier using competitive bids to supply electricity at the best price. You may also shop for and choose another supplier if you prefer. Full details are on the Choose a Supplier page.
