Ameren Missouri

Providing safe, dependable power to meet your energy needs. At Ameren Missouri, we are committed to improving electric reliability in the communities we serve. This is why we are investing millions of dollars in projects throughout our service territory to provide cleaner and more dependable energy for you. We’re replacing old substations with new ones in order to meet your energy needs for decades to come. These are the substations that power critical regional assets, including children’s hospitals, medical centers, major employers and universities as well as police and fire stations. New substations are being built and upgraded lines are being installed in virtually every part of our service territory, from Southeast Missouri to St. Louis to Central Missouri. We’re adding circuits and underground lines to provide additional routes so power will continue to flow in times of emergency. In most cases, you’ll never know if a problem has been detected because there power you need will always be there when you flip the switch. Each year a portion of our poles, cables, equipment and power lines are inspected as part of our Circuit Inspection Program. Repairs are made to ensure the reliability of our system and prevent outages before they occur.¬†Ameren Missouri is part of St. Louis-based Ameren Corporation, with a generating capacity of 10,200 megawatts. Ameren Missouri has been providing electric and gas service for more than 100 years, and our electric rates are among the lowest in the nation. Ameren Missouri’s mission is to power the quality of life for our 1.2 million electric and 130,000 natural gas customers in central and eastern Missouri. Our service area covers 64 counties and more than 500 communities including the greater St. Louis area. But that’s far from all we do or stand for. While we’re busy keeping the power on, we’re also looking forward. We’re involved in programs to protect and conserve our environment, and help our communities prosper and grow.
