Business segments

Ameren is a power company.  The firm operates two reportable business segments:

  • Ameren Missouri – Operates energy centers and delivers electric and natural gas services in Missouri. Includes Ameren Missouri Energy Management & Trading and Ameren Missouri Wholesale.
  • Ameren Illinois – Provides electric and natural gas services in Illinois.

History

1902 saw a merger between three utilities:  Missouri Edison Electric Company, Citizens Electric Lighting and Power Company, and Imperial Electric Light, Heat, and Power Company. The resulting firm was Union Electric, which was incorporated in 1922 as Union Electric Light and Power Company. In 1931 Union Electric bought Keokuk Dam, providing power over a longer distance than ever before.

During World War I Union Electric grew by serving rural areas and acquiring many small light and power companies in Illinois and Missouri. In 1937 it changed its name to Union Electric Company of Missouri, with its Illinois and Iowa operations becoming subsidiaires. In 1945 the Iowa and Illinois divisions were merged into one subsidiary called Union Electric Power Company.

By the 1950s Union Electric was the third largest distributor of natural gas in Missouri. In 1963 it finished building one of the largest pumped storage plants, the Taum Sauk Plant. In 1995 it merged with CIPSCO. A new firm, Ameren Corporation, was then created to serve as a holding company for Union Electric’s operations. Ameren ranked 11th in the U.S. in terms of generating capacity.
