The future of a fixture on the along the Great River Road is uncertain, with the announcement by Ameren that it will be closing the Sioux Power Plant in St. Charles County, Missouri.   The plant was built in 1967 and is slated for retirement by 2033.   It is a coal-fired plant, and Ameren is moving toward more environmentally friendly power generation in the future. 

Ameren’s Ajay Arora tells The Big Z today, the plant is about 2/3 of the way through its expected lifespan.

He says it is too early to know what will become of the plant.  Originally built by Union Electric, it accomplished many industry firsts.  It pioneered slag-removal techniques now used nationwide, was one of the first to install cyclone furnaces that can burn multiple fuels, and became the first generating plant in Missouri to burn chipped rubber tires to augment coal as an alternate fuel source.
