For all relocation projects (due to the planned installation of a building/home addition, garage, out building, shed, swimming pool, hot tub, deck, gazebo or any other structure) contact ComEd in advance of construction of the new structure to ensure required clearances are met.
If you have an existing underground electrical service that requires a relocation, an upgrade or voltage revision (e.g. main service upgrade from 100 amps to 200 amps), the following information is required:
You will be required to submit a completed electric service application. Upon completion of the application, a dedicated ComEd representative will be assigned to your project. After ComEd receives confirmation that the project has passed municipal inspection, it can take anywhere from 8 to 20 weeks to complete the underground electric service, depending on the amount of work required.
Review the overhead service booklet for additional requirements and connection diagrams.
