WHY does Ameren demonstrate a responsibility to customers and communities?

Ameren’s responsibility to 2.4 million electric and more than 900,000 natural gas customers in communities across Illinois and Missouri is clear: Electricity and natural gas are critical in our daily lives. People require energy to heat and cool their homes, and run businesses and schools. The energy we provide is also needed to save lives and respond to emergencies. With such a vital purpose, Ameren strives to keep energy safe, reliable and reasonably priced for all. As a Fortune 500 company, we serve as an engine that powers economic investment and community improvement in Illinois and Missouri.


  • Safe, reliable, reasonably priced energy
  • Quality service and customer conveniences
  • Charitable giving and volunteerism
  • Support of economic development

As part of the ongoing effort to maintain a high level of service reliability for customers and to modernize aging infrastructure, Ameren Missouri and Ameren Illinois installed smart grid technology on multiple energy distribution projects in 2017. Smart grid technology consists of equipment such as "Viper" switches and "IntelliRupters" that can quickly identify and isolate a service issue, which results in faster energy restoration for customers while permanent repairs are being made.
