Is your bill higher than this?

South Dakota bills ran highest in July, about $176, and lowest in October, about $115. Air conditioning does most of the work in summer. If yours is well above $140 in a mild month, your rate, an older air conditioner or the size of your home are the usual reasons.

Homes here use about 990 kWh a month, 13% more than the U.S. average of 870 kWh, and pay 14.20¢ per kWh, 21% lower than the U.S. average of 18.01¢, so the lower price, not lighter use, is what keeps bills below the national average.
