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.  

Yes! With our SimplePay budget plan, you will receive a bill each month for the same amount, making it easy to budget ahead. The amount will be an average of your bills from the last 12 months.
