Budget Billing

Using our Budget Billing Plan is a great choice if you want to even out the seasonal highs and lows of your heating bill. The Budget Bill Plan is available year round and will begin with the next bill following sign-up.

  • We estimate your natural gas usage for the next 12 months, based on your past usage.
  • We divide the last 12 months by 11 to determine your monthly payment amount.
  • The customer pays the budget amount for 11 months. The 12 month is the reconciliation bill; the customer pays actual gas charges plus or minus any under or over collected funds from the estimated budget.
  • A Budget Bill amount may be adjusted to minimize the chance of a large difference at the end of the Budget Billing Plan year
  • A Customer’s Budget Bill amount will be recalculated for each succeeding year that the Customer remains on the Budget Billing Plan
