“levelized payment” or “level pay” plan. Budget-billing plans allow customers to even out their monthly bills, paying more than they would in the summer and less in the winter. Such plans can help consumers minimize their bills during the winter, but it’s important to read the fine print so you understand exactly what you’re agreeing to when you sign up.
How does a budget-billing plan work?
Budget-billing plans DON’T reduce the amount customers pay to heat their homes. Rather, they spread the payments out over a certain period, usually a year. Utilities consider such factors as the total amount a customer paid for natural gas usage the year before, projected gas prices and weather conditions to come up with an estimated monthly budget amount.

The utility will continue to take monthly meter readings to determine a customer’s actual usage and at the end of the designated budget-billing period, the company will compare estimated and actual usage. At this “settlement” time, if actual usage is greater than the estimated usage, the customer will be billed for the difference or that amount will be rolled over into the next year’s bills. Some utilities will allow you to pay off that difference through deferred payment plans lasting four to 12 months, while others may demand immediate payment. If actual usage is less than the estimated amount, then the customer gets a credit. Upon request by the customer, some utilities may pay that credit by check. Also, some utilities pay interest on the credit.
Will a customer’s monthly bill ever change under a
budget-billing plan?
Yes. Budget-billing plans do not necessarily protect you from bill fluctuations. If the price of natural gas changes dramatically or if your actual usage is much higher than the estimated amount, utilities may change your monthly payment so you don’t have a large debt at the end of the budget-billing period.

For example, under Illinois Power’s “levelized payment plan,” the utility reviews a customer’s monthly bill every one to three months, and if the bill increases or decreases by at least $1 from the estimated amount, the utility will adjust the bill to keep the customer’s payments evened out. Peoples Gas reviews a customer’s account each month, and will change the monthly installment if your payment needs to change by at least 25 percent. Smaller changes will be adjusted every six months.
How is Nicor Gas’ budget-billing plan different from other utilities’ plans?
Nicor is the only major utility in the state that charges budget-billing customers interest on an unpaid balance. Nicor and other utilities pay interest on credit balances accrued by customers, but Nicor is the only company that charges interest on the unpaid balance. See the back of this page for more information on the budget-billing plans of major Illinois utilities.
