How is my energy usage measured?

Energy usage is typically measured by a device known as a meter, which is installed either on the exterior of your home or in a designated area inside. Ameren Illinois uses various types of meters, including analog and digital smart meters. These meters record the amount of electricity or gas consumed over a specific period, usually on a monthly basis. When a reading is taken, the meter measures the difference between the current reading and the previous one, providing an accurate account of usage during that time frame. Smart meters also have the capacity to provide real-time data on energy consumption, enabling customers to monitor their usage more closely and change their habits if necessary. This information can typically be accessed through online platforms and apps provided by Ameren. For more detailed inquiries about your specific meter reading and billing, you may want to refer to the information available on the Ameren Illinois website.
