Ameren Files for 2,100 MW Gas Plant in MO – Will M-U Gas Feed It?

Ameren Missouri (a subsidiary of Ameren Corporation) announced yesterday that it has filed an application with the Missouri Public Service Commission (MoPSC) to build the West Alton Energy Center, a 2,100-megawatt (MW) combined-cycle natural gas power plant. The company expects the plant to come online in 2031, pending regulatory approval, and to create more than 1,000 construction jobs plus roughly 45 permanent positions. Ameren will build it right next door to its existing coal-fired Sioux Energy Center in West Alton, Missouri — sitting at the confluence of the Missouri and Mississippi rivers just upriver from St. Louis — so it can reuse the transmission connections and other equipment already on site. Company officials pitched the project as around-the-clock, in-state generation that will "work alongside our other resources" as older plants retire and demand climbs. Translation: Missouri needs power that shows up whether or not the wind blows or the sun shines.
