The deferred balance amount is the cumulative difference between your monthly Average Monthly Billing amount and what you would owe if you were not signed up for Average Monthly Billing. The deferred balance amount can be found on your monthly bill. If the bill amount is positive, 1/12 will be added to your bill. If the bill amount is negative, 1/12 will be subtracted from your bill. If you're a new Average Monthly Billing customer, the deferred balance will begin in the second month. The deferred balance must be paid in full if you cancel Average Monthly Billing or change electricity providers.
