About ComEd
Commonwealth Edison (ComEd) is Illinois’ largest electric utility, serving over 3.8 million customers across northern Illinois, including Chicago and its surrounding suburbs. While ComEd doesn’t generate electricity, it’s responsible for delivering power to your home, maintaining power lines, and responding to outages. As a subsidiary of Exelon, ComEd has been delivering electricity for more than a century, managing over 90,000 miles of power lines across an 11,400-square-mile territory.
ComEd is known for its commitment to clean energy and grid modernization, investing in smart technology to reduce outages and improve efficiency. They also offer a variety of rebates, discounts, and energy-saving programs to help customers lower their bills and reduce their carbon footprint.
ComEd’s Service Area
ComEd’s service territory stretches from the Wisconsin border down to Pontiac, Illinois, and from the Indiana border westward to the Mississippi River. This expansive area includes major cities like Chicago, Aurora, Rockford, Naperville, and Joliet, covering approximately 70% of Illinois’ population.
Where Does ComEd’s Energy Come From?
ComEd purchases electricity from a mix of sources, including renewable energy like wind and solar, natural gas, nuclear, and coal. Illinois is a leader in clean energy, with a significant portion of its power coming from nuclear and renewable sources. If you’re environmentally conscious, you can opt for a retail supplier that offers 100% renewable plans or take advantage of ComEd’s renewable energy programs.
ComEd is actively working towards a greener future. In 2023, all 54 of its facilities were powered with over 70,000 MWh of carbon-free energy, preventing more than 21,000 metric tons of carbon emissions.
Choosing a Retail Electric Provider (REP)
While ComEd delivers your electricity, you can choose who supplies it. This is where retail electric providers (REPs) come in. REPs offer different rates, contract terms, and renewable energy options, giving you more control over your energy costs.
Why Choose a REP?
- Potential savings: Some REPs offer lower rates than ComEd’s default supply price.
- Renewable energy options: Many REPs provide 100% green energy plans.
- Fixed-rate plans: Lock in a steady rate instead of dealing with seasonal price fluctuations.

Community Solar Programs

ComEd is expanding access to solar energy through community solar projects.

- Energy Generation: The solar farm produces electricity, which is fed into the local grid.
- Bill Credits: Subscribers receive credits on their monthly ComEd electric bills based on their share of the solar energy produced, effectively reducing their energy supply charges.
- Dual Billing: Participants receive two bills: one from ComEd reflecting the solar credits and another from the solar developer for the subscription fee.
Benefits:
- Cost Savings: Subscribers can save approximately 5-10% annually on electricity costs.
- Accessibility: No need for personal solar panel installations, making it accessible to a broader range of customers.
- Environmental Impact: Supports the growth of renewable energy and contributes to reducing carbon emissions.
