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.

Things to Consider When Choosing a REP

  • Rate vs. ComEd’s Price-to-Compare: Always check if the REP’s rate is lower than ComEd’s default rate.
  • Contract terms: Avoid long-term contracts if you prefer flexibility.
  • Early termination fees: Some REPs charge fees if you cancel early.
  • Customer reviews: Look for feedback on billing accuracy and customer service.
  • Renewable Content: If sustainability is important to you, look for REPs offering green energy plans.

Grid Modernization and Renewable Integration

To support the growth of renewable energy, ComEd is investing in grid modernization. These investments are essential to accommodate new technologies and renewable energy sources, ensuring reliable delivery of clean energy to customers.

Community Solar Programs

ComEd Community Solar

ComEd is expanding access to solar energy through community solar projects. In 2023, over 54,000 solar systems and related energy storage facilities were connected to the ComEd system, including the 100th community solar site in northern Illinois. These projects enable approximately 25,000 residential customers to benefit from solar energy without installing panels on their own homes.

How It Works:

  • Subscription Model: Customers subscribe to a share of a local solar farm operated by third-party developers.
  • 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.
Give-A-Ray Program: Targeted at income-eligible customers, this initiative covers subscription fees, providing significant savings, up to $1,000 annually, for participants.

Enrollment:

Interested customers can find more information and sign up through ComEd’s official website or by contacting approved community solar developers in their area.

Supporting Electric Vehicle Adoption

ComEd is also facilitating the adoption of electric vehicles (EVs) by preparing to power up the state’s largest EV battery plant. This initiative is part of a broader effort to support the clean energy transition and economic development in northern Illinois communities.

Innovation and Customer Engagement

Through programs like Customer Innovation, ComEd is exploring new ways to make energy efficiency, electrification, and distributed energy resources more accessible and effective for all customers.

If you value reliability, clean energy, and strong customer support, ComEd is a solid choice. While you can stick with their default supply, shopping around for a REP could save you money or align better with your environmental goals.
