Is your bill higher than this?

Illinois bills ran highest in July, about $193, and lowest in November, about $105. Air conditioning does most of the work in summer. If yours is well above $132 in a mild month, your rate or plan, an older air conditioner or the size of your home are the usual reasons.

Homes here use about 700 kWh a month, 20% less than the U.S. average of 870 kWh, and pay 18.79¢ per kWh, 4% higher than the U.S. average of 18.01¢, so lighter use, not the price, is what keeps bills below the national average.

Illinois lets you pick your electricity supplier

Most homes can buy power from a competing supplier while the local utility still delivers it, so the rate you pay depends on the supplier and plan you chose.
