Why does my average amount change every month?

Your usage and payment history are reviewed monthly to determine if your account is ahead or behind in paying your energy usage. When you start on Average Billing, your monthly payment is calculated based on estimated usage. Each month, your actual usage and payment history are reviewed to make updates to the average monthly payment amount. This helps to ensure that you aren't using more energy than you are paying for or paying for more energy than you are using. This helps avoid a large "wash up" (Accumulated Average Balance) at the end of the year.
