Ameren History and Energy Deregulation

Ameren itself is a relatively young company, first incorporated in Missouri 1995 and becoming a major player in 1997 when the Union Electric Company in Missouri and the Central Illinois Public Service Company, which would become Illinois Rate Zone I, joined forces. The company then acquired the Central Illinois Light Company – Rate Zone II – in 2003 and Illinois Power Company – Rate Zone III – in 2004. Ameren operated in Illinois as three separate utilities before combining into one company with three rate zones in 2010. Both Union Electric and CIPS date back as far as 1902.

In 1997, Illinois legislation restructured the utility generation and delivery model allowing third-party providers to deliver electricity. This is called Energy Choice or Electric Choice. Ameren customers now have the ability to choose between basic generation service delivered by Ameren or a competitive rate delivered by a third-party provider. The benefit of Electric Choice is the low fixed-rates that customers are offered as a result of energy companies competing for your service.
