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.


To ask a question or dispute a bill, you can call 800.750.4000, send us an email, or write to CMP Customer Service at 83 Edison Drive, Augusta, ME  04336.

Payment Arrangements

If you have trouble paying your bill, a payment plan may help. Call 800.750.4044 for more information or learn more about available assistance programs.

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.

Report a Power Outage

Call 800.696.1000.  If call volume is heavy, an automated system will log your call and generate a repair order.

Sales-Tax Exemption

Maine sales tax does not apply to the first 750 kilowatt-hours (KWH) of residential dwelling.

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.

Estimated Bills

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.
