Utilities Electricity for most of northern Illinois is provided by Commonwealth Edison, also known as ComEd. Their service territory borders Iroquois County to the south, the Wisconsin border to the north, the Iowa border to the west and the Indiana border to the east. In northern Illinois, ComEd (a division of Exelon) operates the greatest number of nuclear generating plants in any U.S. state. Because of this, ComEd reports indicate that Chicago receives about 75% of its electricity from nuclear power. Recently, the city began installing wind turbines on government buildings to promote renewable energy.
