ComEd Electric Bills Went Up

ComEd electric bills went up—here's what to know:
Starting June 1, 2025, ComEd’s electricity supply rate went up to about 10 cents per kilowatt-hour. That’s a 45% increase from this time last year, when the rate was 6.9 cents.
For most customers, that means paying around $10.60 more every month on their electric bill.
This increase applies to the supply and transmission part of the bill—not the delivery. Supply and transmission usually make up more than half of the total bill.
ComEd says it does not make a profit from this part of the bill and that it simply passes these supply costs along to customers.
The new rate is expected to stick until October.
What they're saying: ComEd says the increase comes from a power auction held last year by PJM Interconnection, a company that manages the electricity grid in northern Illinois. ComEd says it was not involved in the auction and doesn’t keep any of the extra money from the higher rates.
"These costs go into effect in June and will be reflected in the 'supply' portion of customer bills, which ComEd passes on directly to customers with no markup. ComEd does not profit from this increase, was not part of the auction, does not supply capacity, and does not retain any proceeds of the capacity charge payments. ComEd is responsible for the "delivery" portion of bills, which pays for the work ComEd does to maintain and upgrade the system to ensure safe and reliable electric service for all customers," ComEd said in a statement.
AG Raoul's Response
Illinois Attorney General Kwame Raoul had been trying to lower the prices that led to this rate increase.
Back in April, he filed a complaint with federal energy regulators asking for a do-over of the electricity auction that caused the price jump.
Raoul said the rules used in the auction were flawed and unfair to consumers, and asked that the auction be rerun under improved rules that were already approved for future use.
He also said if the auction wasn't redone before the higher prices went into effect, then he wants the government to order refunds for customers based on the lower prices a fairer auction would produce.
Raoul said a rerun of the auction could cut the price increase in half.
What we don't know: It’s unclear how much relief ComEd customers will see from a credit tied to a state energy law, the Climate and Equitable Jobs Act (CEJA), which is expected to vary month to month.
"We’re glad CEJA gives customers some relief in the short term, and in the long term, we will continue to work at fixing the root causes of this price spike, mainly poor policy from PJM Interconnection, the power grid operator for northern Illinois," said Sarah Moskowitz, Executive Director of Citizens Utility Board (CUB). "As we advocate for pro-consumer reforms at PJM and the State Capitol, we also urge ComEd to work with customers to keep them connected this summer."
What's next: So far this year, ComEd says it's helped more than 100,000 customers get $31 million in financial help. You can visit ComEd.com/BillSupport to see what assistance programs you may qualify for.
CUB has also set up a website—CUBHelpCenter.com—with tips for saving energy and getting bill help.
Next Year
ComEd customers may face another steep price increase in 2026 and 2027.
According to the Illinois Radio Network, grid operator PJM Interconnection announced the results of its base residual auction on Tuesday and said some customers could see an increase of 1.5% to 5% in their bills.
Capacity Charge Updates
The Capacity Charge increased in June 2025 for all ComEd customers, including Hourly Pricing participants. Learn what this means for your energy bill and how you still have an opportunity to save with Hourly Pricing.
Understanding Changes to Your Capacity Charge
Electric utility customers pay capacity charges. This supply cost is power for your use now and in the future, ensuring there will be enough capacity when you need it. The Capacity Charge is a standard item on all customers’ bills and changes every June based on your energy usage from the previous summer and the Capacity Charge Rate, which is determined by electricity market conditions.
The Capacity Charge is included as a portion of all customers’ monthly bills, either as a separate line item for Hourly Pricing participants or within the Electricity Supply Charge for default fixed-price rate customers.
Why did the Capacity Charge increase?
The Capacity Charge increased due to rising supply costs, which is the price ComEd pays for electricity on the wholesale market. These costs are passed directly to you with no markup.
“Supply” represents the amount of electricity a customer uses. ComEd is responsible for the “delivery” portion of your bill. Delivery costs pay for the work ComEd does to maintain and upgrade the system to ensure safe and reliable electric service for all customers. The Illinois Commerce Commission reviews and approves the ComEd delivery rates.
The Capacity Charge increased for all ComEd customers in June 2025. On average, the monthly residential customer bill in the ComEd service territory is expected to rise by about 10%.

How Does This Affect Hourly Pricing Participants?
Hourly Pricing participants can expect to experience a similar level of savings as they have in the past since the Capacity Charge rose at the same level for the hourly rate and the default fixed-price rate.
As an Hourly Pricing participant, you pay for electricity at the hourly market price and can still take advantage of lower-priced hours to see savings in the long run.

How to Manage Your Energy Bill
Making small adjustments to your energy use can help you lower your energy supply costs and manage your future Capacity Charge starting next summer. You can expect to see a similar level of savings on Hourly Pricing since the Capacity Charge rose at the same level for both the hourly and default fixed-price rates.
Hourly prices typically follow predictable seasonal patterns, so it can be easy to shift your energy use to save money.
Reducing your energy use, especially for large appliances, during high-demand hours this summer can lower the Capacity Obligation on your bills starting in June 2026. Shifting your usage during hot summer afternoons between 2 p.m. and 6 p.m. can have the biggest impact on your future bills.
Precool your home at night to avoid high energy costs during the day, especially during hot summer afternoons. Review the Summer Guide for more helpful tips to reduce your energy use.
Hourly Pricing Alerts can help you reduce your future Capacity Charge. Real-time alerts notify you if the current price of electricity is trending high, and day-ahead alerts notify you if energy is expected to be in high demand during specific hours the next day. If you use less energy during the day-ahead alert period, you could lower your Capacity Charge for the following year.
