How Average Monthly Billing is calculated

  • Your Average Monthly Billing payment amount is based on the average dollar amount of your last 12 months' bills.​​​
  • Each month, the difference between the average amount that you are billed and the actual usage is placed into a deferred balance, either as a credit or debit.
  • One-twelfth of the deferred balance is applied to your ave​rage amount on each bill, and the sum is rounded to the nearest dollar to determine your total Average Monthly Billing amount.

Things to know​

If you close your account or if service is turned off for non-payment or if your account becomes two months past due, your Average Monthly Billing plan will be discontinued.

​​

If you de-enroll or if you are removed from the program, we will review your account and send you a bill with the difference between what you have paid on the Average Monthly Billing plan and the amount of natural gas you have used.

  • If you have paid more for natural gas than you have used, we will issue you a credit.
  • If you have an outstanding deferred balance, a deferred payment agreement may be available to qualifying customers.
