Information for Your Electricity Delivery Service
Delivery rates are approved by the Maine Public Utilities Commission. For bills that cover both electricity supply and CMP delivery, CMP forwards energy-supply payments to the appropriate energy provider. For a schedule of CMP delivery rates, call 800.750.4000.
CMP's Delivery Role Under Maine Law
The State of Maine changed the electricity-utility business as of March 1, 2000. The law now separates electric supply from its delivery. You may choose a competitive energy provider, or automatically take energy from the Standard Offer provider. CMP no longer generates electricity. We operate the system that delivers your electricity, and we service your account.

Late Payment Charge
Bills are due on receipt. A late charge of .267% will be applied each month to the unpaid balance after 25 days from the bill postmark.

Call 800.696.1000. If call volume is heavy, an automated system will log your call and generate a repair order.
Maine sales tax does not apply to the first 750 kilowatt-hours (KWH) of residential usage.
What's a kilowatt-hour?
Electric power is measured in watts. 1,000 watts of power used for one hour is a kilowatt-hour (kWh) of energy. Example: a 100 watt bulb lit for 10 hours uses one kWh of energy.
When we cannot read your meter, we will estimate your usage for the month. You have the right to read your own meter. Call us at 800.750.4000 for more information.
