Is your bill higher than this?

Idaho bills ran highest in July, about $153, and lowest in October, about $92. Air conditioning does most of the work in summer. If yours is well above $114 in a mild month, your rate, an older air conditioner or the size of your home are the usual reasons.

Homes here use about 900 kWh a month, 4% more than the U.S. average of 870 kWh, and pay 12.65¢ per kWh, 30% lower than the U.S. average of 18.01¢, so the lower price, not lighter use, is what keeps bills below the national average.
