The official formation of the Ameren Company occurred on December 31, 1997, through a 'merger of equals' between Union Electric Company and CIPSCO Inc. This event marked a significant consolidation in the utility sector, creating a larger entity with a broader operational scope.

The merger brought together two companies with deep roots in the energy sector. Union Electric Company, formed in 1922, and CIPSCO Inc., which traces its origins back to 1902, both had long histories of providing essential services. This merger was a strategic move to enhance market presence and operational efficiency.

Charles W. Mueller, the CEO of Union Electric Company, and Clifford L. Greenwalt, who led CIPSCO Inc., were key figures in the merger that created Ameren. The merger of these two entities was a pivotal moment in the evolution of the utility industry. It set the stage for the Ameren Corporation as it is known today.
