Ameren Illinois upgraded 1.2 million electric meters and over 800 natural gas meters. If the meter at your location needs updating or exchanged, we will use normal operational practices. Please make sure there is nothing blocking access to the meter, such as locked gates or locked doors. If Ameren can safely access the meter at your home or business, you don’t need to be present at installation or exchange. If you normally have to allow a meter reader access to the meter in your home or business, you will need to be present to allow the installer access to the meter.

The meter upgrade will take less than 15 minutes to complete at your premise. Installers from Ameren Illinois will knock on your door to inform you that they are installing the device. Meter installers can be identified as Ameren employees or Ameren contractors by their ID badges and by Ameren or the contractors name on their vehicles. If you are not present during the upgrade, a door hanger will be left behind, notifying you that the upgrade took place.

Yes, for electric residential customers, brief electrical service interruption will occur during the first 10 to 15 minutes of the meter upgrade. Both residential and smaller commercial customers may need to reset any digital clocks on appliances and electronics. We apologize for any inconvenience this may cause. For larger electric commercial installations, there is typically no service interruption and there is no service interruption when we upgrade the gas meter.

It depends on the type of meter used at the residence or business. Those with an analog meter, when the smart meter is installed, there will be no noticeable changes, and a meter reader will still be sent to their premise to gather monthly energy usage for a period of time after. However, this will change as Ameren continues to improve our network and starts to read energy usage remotely. Those with an automated meter that uses one-way communications, when the smart meter is installed, the meter reads will continue to be read wirelessly. In addition, we will let you know when new benefits become available following meter installation. To learn more, visit: www.AmerenIllinois.com/SmarterOptions. 

If we are unable to access the existing meter, we will leave behind a door hanger with information to contact Utilitra, our installation contractor, at 1.866.849.1905 to reschedule the meter upgrade appointment.

Ameren Illinois 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 1-800-755-5000 if you would like an application for this registry or if you want to confirm your account is still registered. Also, if you are already in our medical registry, we will schedule an appointment with you to complete the meter upgrade.

If you have questions related to scheduling an appointment or meter installation, please Ameren Illinois.com customer service at 800.755.5000 for any questions.

If you decide that you do not want a smart meter, you have the option to enroll in our Non Standard Metering (NSM) service. Unlike our Standard Metering service, which uses the smart meter to transmit your energy usage wirelessly to Ameren Illinois, the Non Standard Metering service will require a manual meter read. There are monthly fees to participate in the Non Standard Metering program and no additional charge for the smart meter. The NSM fees 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 800.755.5000 to learn more about the fees.

Just like older meters, smarter meters collect energy usage data. Smart meters also collect additional operational data such as hourly usage data, voltage data, outage data and diagnostic flags to help us provide more reliable service to you. Smart meters do not collect, store or transmit personal identifying information such as names and addresses or social security numbers.

We use our customer’s energy usage and operational data for billing purposes and troubleshooting and resolving problems with equipment or services. In addition, customers can view hourly energy usages which can help better manage energy usage and costs, even on the go. Customers can create an online account, enroll in a demand response program, called Peak Time Rewards, sign up for alerts or purchase a Home Area Network. If Home Area Network is available to you, a link will be present on the Ameren app which can be downloaded from the app store on a smart mobile device. 

No. We treat personal information and data about our customers as confidential. You retain ownership of your own privacy data (including energy usage), and Ameren Illinois will not disclose that information to external parties without your permission, except for official Ameren Illinois business or as required by law.

We have extensive cybersecurity measures in place throughout the Advanced Metering Infrastructure network to secure and protect customer data. First, access to meters and usage data is controlled with authorization requirements. Second, information is secured at the meter and all the way back to our systems with advanced encryption. Third, we placed all pole-top network devices in locked and alarmed boxes to prevent unauthorized access. Fourth, data from the network must pass through firewalls and security components before reaching Ameren. Finally, all access to the Advanced Metering Infrastructure system is logged and recorded to alert us of unusual activity.

Our smart meters communicate using a low-power radio frequency (RF) signal. Radio frequency is another term for radio waves or wireless signals. This allows for the two-way wireless communication between Ameren and the meters through our next generation energy delivery system

Research and studies have been conducted on radiofrequency (RF) fields and health for several decades, and this body of research has been reviewed by many public health and regulatory agencies. None of these organizations have found that the RF signals from smart meters cause or contribute to any adverse health effects. In addition, the meter transmits RF for only a few minutes each hour at an extremely low signal strength level comparable to other home devices such as cordless phones or wireless baby monitors.

You probably have one or more commonly used household devices that transmit and receive data using radio frequency signals, including video game controllers, cell phones, televisions, computers, baby monitors, radios, security systems, garage door openers and Wi-Fi routers.

The Food and Drug Administration (FDA), Federal Communications Commission (FCC), World Health Organization (WHO), American Cancer Society (ACS) and National Cancer Institute (NCI) consider smart meters safe.

The wireless signal from smart meters is weaker than that of most common household wireless devices. If other wireless devices in your home do not interfere with your medical device, it is extremely unlikely that a smart meter will interfere. However if you suspect interference, please let us know so we can investigate a solution. Also, the wireless signals from advanced meters comply with all Federal Communications Commission (FCC) regulations for commonly used consumer wireless devices.
