ComEd Electricity Area

The Commonwealth Edison (ComEd) electric utility is one of the largest electric utilities in the country. ComEd serves more than 3.8 million customers as an electric delivery company; that is ComEd is in charge of delivering the power from the generation plants to the consumers (households, offices, schools, malls, etc.).

Before deregulation ComEd was also in charge of generating the electricity that ComEd customers consume. That has now changed, though many electric consumers are still on the ComEd default rate. ComEd earns money from the delivery charges found on the ComEd monthly electric bill. The delivery charges remain regulated by the Illinois Commerce Commission and are the same no matter which electric supplier a customer chooses.

The generation and transmission charges make up what is known as the “Price to Compare”. This is the rate that is open to competition. Consumers in Illinois try to find an electric rate from a competitive supplier that is lower than the ComEd price to compare. When you choose to buy power from a competitive supplier, the rate offered will include both generation and transmission charges.
