ComEd Utility: Service Territory, Rates & Electric Choice
Learn how the ComEd utility works, what its service territory covers, how electricity delivery differs from supply, and how customers can compare ComEd electricity rates, suppliers, contracts, and pricing options.
When searching for ComEd utility, ComEd service territory, or Commonwealth Edison, consumers are often trying to answer a simple question: who supplies their electricity, who delivers it, and can they choose a different supplier?
For customers in the ComEd service territory, understanding that distinction is important. ComEd remains responsible for delivering electricity through its distribution system, while eligible customers can generally choose who supplies the electricity itself. Illinois' official electric-choice guidance confirms that customers in the ComEd service territory can choose among utility supply, alternative retail electric suppliers, and residential real-time pricing options.
That means comparing electricity plans is not simply about finding the lowest advertised rate. Customers should also consider contract length, rate structure, supply charges, delivery charges, fees, renewal terms, and expected electricity usage.
What Is ComEd?
ComEd, short for Commonwealth Edison, is the electric utility responsible for delivering electricity across its service territory.
The utility's role is primarily associated with the electric grid and delivery infrastructure. This includes the distribution network that brings electricity to homes and businesses and the service responsibilities associated with that network.
ComEd customers can also have a choice regarding the company that supplies their electricity. Choosing a different electricity supplier does not mean replacing the utility responsible for delivering electricity.
The Illinois Commerce Commission explains that electricity service has separate supply and delivery components. Customers in the ComEd service territory can choose the provider of the supply portion while the utility continues to provide delivery service.
What Is the ComEd Service Territory?
The ComEd service territory is the geographic area in which Commonwealth Edison operates its electric distribution system.
If your address is served by ComEd, the utility remains responsible for delivering electricity to your property regardless of which eligible supplier provides the electricity supply.
