ComEd is an energy delivery company. We do not own power plants and we do not make electricity. We deliver electricity to your home or business. To do this, we manage more than 90,000 miles of power lines in an 11,400-square-mile territory. Since 2001, we have invested more than $5 billion in our electrical transmission and distribution system to continue to provide customers like you with the quality service you expect and deserve.

Providing safe, reliable electric service to our 4 million customers is just part of what we do. We also help you discover new ways to save money on your electric bill and show you how you can help the environment by decreasing your carbon footprint. We're doing our part for the environment as well.
