How it works

Arbor is a free service that monitors the market for the best electricity rates in your area. Here’s how it works:

1) Link your CMP bill

Link your Central Maine Power account via your username, account number, or by uploading a bill so that Arbor can see what you are currently paying.

2) Get your rate lowered

When a lower rate is available, we show you how much you will save compared to your current rate, and then do the work for you to reserve it on your usual CMP bill.

3) Save with no interruptions

You will see a lower rate on your CMP bill - everything else stays the same! There are no service changes or commitments, and Arbor monitors the market on an ongoing basis to keep getting you the best rate. It is 100% free - Arbor is not a supplier and only gets compensated from electricity suppliers when you get a better rate on your usual CMP bill. Arbor will continue to monitor your rate compared to what is available. 

The sign up process only takes two minutes. Link your account today and start saving on your CMP bills.
