Compare ComEd Electricity Rates

When it comes to managing your energy costs in Illinois, understanding and comparing ComEd electricity rates can help you make smarter financial decisions. Whether you’re a homeowner or a small business owner, choosing between sticking with ComEd’s default supply service or switching to an alternative energy supplier can significantly impact your monthly electric bill. 

What is ComEd? 

Commonwealth Edison, commonly known as ComEd, is the largest electric utility in Illinois, serving over 4 million customers. It operates as a suppliers utility, meaning it both delivers electricity and, for many customers, supplies it as well.

 However, ComEd is a regulated utility and does not generate electricity; instead, it purchases it on the wholesale market and passes that cost to consumers with no makeup. 

This setup allows you, the consumer, to shop around for your electricity supply through the state’s Energy Choice program while ComEd continues to deliver the electricity to your home or business, maintain the power lines, and respond to outages. 

Understanding ComEd Electricity Rates

ComEd electricity rates for supply service are updated periodically and are approved by the Illinois Commerce Commission. These rates typically reflect the wholesale cost of power and can fluctuate depending on market conditions. 

As of the most recent updates, the supply charge from ComEd is measured in cents per kilowatt-hour, and it’s separate from the delivery charges. While delivery charges are regulated and fixed, supply rates are where you have a choice and potential savings. 

For example, if ComEd’s current supply rate is 7.8 kWh for a 12 month term. That difference might seem small, but over a year, it can add up especially for high usage households. 

Choosing Between ComEd And An Alternative Supplier 

When comparing ComEd electricity rates to those offered by alternative suppliers, it’s important to consider a few factors: 

  • Fixed vs Variable Rates – ComEd offers a standard fixed rate. Some alternative suppliers utility companies offer variable rates that can change month to month. Variable rates can be risky if market prices spike.  
  • Contract Terms – Alternative suppliers often require you to sign a contract for a set period. Make sure you’re aware of early termination fees. 
  • Renewable Energy Options – Many third party suppliers offer green energy plans, which may be slightly more expensive but contribute to sustainability goals. 
  • Customer Service And Reputation – Check reviews and ratings of any supplier before switching. Good customer support can be crucial, especially when resolving billing or contract issues. 
  • Hidden Fees – Some suppliers may advertise low rates but include additional fees in the fine print. Always read the terms and conditions carefully. 

How To Compare ComEd Electricity Rates 

There are several online tools and official state-run websites like the Illinois Commerce Commission’s Plug In Illinois that let you compare ComEd electricity rates side-by-side with rates from other suppliers utility companies. These platforms are user-friendly and help you view: 

  • The price per kWh 
  • Term Length 
  • Renewable Content 
  • Any Applicable Fees 
  • Supplier Contact Information

Using these tools, you can quickly determine if switching from ComEd’s default rate will save you money. 

Is It Worth Switching? 

In many cases, switching to a third-party supplier can result in savings, especially when market rates are low. However, some customers have found themselves paying more due to variable rates to overlooked contract terms. That’s why it’s essential to compare carefully, consider your electricity usage habits, and be mindful of contract details. 

It’s also worth noting that ComEd’s supply rates tend to be competitive because they reflect the real time wholesale market, and they don’t profit from the sale of electricity. This neutrality can make them a relatively safe option if you prefer not to shop around or manage contracts. 

In a deregulated energy market like Illinois, consumers are empowered to choose who supplies their electricity. By taking the time to compare ComEd electricity rates with those of other suppliers utility companies, you can find a plan that better fits your lifestyle and energy goals. 

Remember, while ComEd will always be your utility provider for delivery and maintenance, your electricity supplier is up to you. Just make sure to read the find print, understand your usage, and make an informed decision. Doing so can lead to consistent savings and peace of mind.
