You enter your zip code and current power usage and it analyzes to find the best plan.

The big benefit of this plan calculator is when you input your power usage by month. Just go back through your previous bills to gather your monthly power usage and put it into the plan calculator. A lot of the power plans have a gimmick of a low rate if your usage is exactly 1 kWh or 2 kWh.

One recent change to the plan calculator is a password was added. The password is given in the text below the calculator.

They also offer free rate monitoring. They analyze new rates everyday automatically contact you if you can save even if you have to pay a cancellation fee.
