Ameren Missouri has a medical equipment registry, and all medical registry accounts are tagged at the meter to alert the installer. Please call our customer service number at 800.552.7583 if you would like an application for this registry or to confirm that your account is still registered.
If you are already in our medical registry, we will schedule an appointment with you to complete the meter upgrade. Please note that you will need to be at home and give consent in order for us to complete the upgrade. If you are not home for the upgrade appointment, you will need to reschedule for a time when you can be home and give consent.
If your meter has a yellow, blue or green label with the words "Type FOCUS AXRe," or "Type E650 S4x," you have an upgraded smart meter.
All meter types at Ameren Missouri are tested routinely for accuracy, including new and in-service meters. In fact, the tests that we conduct meet or exceed Missouri's regulatory requirements. Our test equipment, methods and documentation are subject to continuous review by Ameren Missouri and meet Missouri Public Service Commission accuracy requirements.
In addition to Ameren Missouri's tests, all of our smart meter suppliers test 100 percent of the meters for accuracy, utilizing very precise equipment during the production process.
We have extensive cybersecurity measures in place throughout the AMI network to secure and protect customer data.
