From the Good Energy website:  Homefield Energy has won a two-year contract with Illinois residents, pursuant to which Homefield will supply energy at a fixed low cost. Through the middle of May 2012, residents of Illinois still had the opportunity to "opt-out," meaning their business would stay with Ameren Illinois, instead of transferring to Homefield Energy. The difference between the two companies is only the cost per kilowatt hour of energy consumed. Good Energy traveled around the state speaking at public meetings and answering questions and concerns about municipal aggregation. Their goal was to make the public's transition to Homefield Energy, a subsidiary of Ameren Corporation, which also owns Ameren Illinois, as easy as possible.
