As the annual rate is no longer available, the Bill Estimator Tool does not provide estimations for annual rate. The Bill Estimator Tool cannot estimate charges for an hourly rate. If you are an hourly rate commercial customer, the Bill Estimator Tool can only provide you with the estimates for ComEd costs associated with your electric energy bill. If you are an hourly rate customer interested in obtaining a total-bill estimate, or you want to learn more about the hourly rate, please contact our Business Customer Service Center at 1-877-4COMED1 (1-877-426- 6331).
