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 you decide that you do not want a smart electric meter or gas module, you have the option to enroll in our Non Standard Metering (NSM) service. NSM service requires Ameren Missouri to visit your property monthly to collect energy usage information. There is a non-refundable $100 setup charge to install a non-standard meter, and a $40 monthly charge to help cover the cost of monthly manual meter reads.
If you decide NSM is the right choice and want to enroll, please call our Customer Service at 866.665.7873 or send a letter of request to:
