ComEd began as the Western Edison Light Company, one of several companies owned by inventor and researcher Thomas Edison. In July 1892, another Edison employee moved to Chicago to run Edison's local company, Chicago Edison. Sam Insull had a sharp business mind and eagerly increased his knowledge of electricity. Through improved marketing and increased demand for electric lighting, Commonwealth Edison was born in September 1907. ComEd is a unit of Chicago-based Exelon Corporation, a Fortune 100 energy company with approximately 10 million electricity and natural gas customers. ComEd powers the lives of more than 4 million customers across northern Illinois, or 70 percent of the state’s population. ComEd's service territory borders Iroquois County to the south (roughly Interstate 80), the Wisconsin border to the north, the Iowa border to the west and the Indiana border to the east.
