Customer 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 1-800-750-4000. Our TTY number for the deaf is 1-800-445-5631.
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 1-800-750-4000, send us an e-mail, or write to CMP Customer Service at 83 Edison Drive, Augusta, ME 04336.

What’s a kilowatt-hour?
