How to choose the best electricity plan
Don't choose a Joliet electricity supplier based only on the advertised cents-per-kWh rate. Compare the complete supply price, contract terms, monthly charges and ComEd's current Price to Compare.
Compare My ZIP Code
500 kWh
Apartment or lower-usage household
Lower-usage customers should pay particular attention to monthly recurring charges because fixed fees can have a larger effect on the effective cost per kWh.
1,000 kWh
Standard comparison level
1,000 kWh is a useful comparison benchmark, but your actual Joliet electricity usage may be higher or lower.
Summer
Air conditioning can raise usage
Cooling demand can increase household electricity consumption during hot Illinois summer weather.
Winter
Heating source matters
Homes using electric heating can have substantially different winter usage from homes heated with natural gas.
Understand your bill
What determines your Joliet electric bill?
Your electricity supplier is only one component of your final bill. ComEd delivery charges and other applicable charges also affect what you pay.
Electricity supply
This is the portion associated with the electricity supply itself. Eligible Joliet customers may receive supply from ComEd or an alternative retail electric supplier.
ComEd delivery
ComEd operates the distribution system that delivers electricity to customers in its service territory. Delivery charges remain applicable regardless of supplier choice.
Transmission and adjustments
ComEd's Price to Compare combines electric supply and transmission components. Other adjustments and delivery charges can affect the final bill.
Before you switch
Five things to check before choosing a Joliet plan
Compare the supplier's effective price with the current ComEd Price to Compare.
Check whether the offer is month-to-month, 6 months, 10 months, 12 months or longer.
A monthly recurring charge can materially change the effective cost, particularly for lower-usage households.
Determine whether you can leave the contract without a cancellation fee, including if you move before the term ends.

Joliet electricity FAQ
Frequently asked questions
Important things to know before switching electricity suppliers in Joliet.
Who are the best electricity providers in Joliet?
The best supplier depends on your ZIP code,
electricity usage, preferred contract length,
rate structure and budget. Joliet customers
in the ComEd service territory can compare
ComEd supply service with eligible alternative
retail electric suppliers.
What is the ComEd electricity rate in Joliet right now?
ComEd's summer 2026 Price to Compare is
10.399 cents per kWh from June 1 through
September 30, 2026. This represents electric
supply and transmission charges and is not
the complete delivered electricity bill.
Is Joliet served by ComEd?
Much of Joliet's residential electricity market
is served by ComEd. Exact utility service should
always be confirmed using the customer's
electricity bill or ZIP/service address because
utility boundaries do not always follow city
boundaries.
Does Joliet have deregulated electricity?
Illinois has a competitive electricity supply
market. Eligible customers in the ComEd service
territory can generally choose who provides
their electricity supply while ComEd continues
to provide delivery service.
Is a 11.19¢ electricity plan cheaper than ComEd?
Not based on the supply rate alone. ComEd's
summer 2026 Price to Compare is 10.399¢ per kWh,
although the comparison can be affected by the
Purchased Electricity Adjustment, supplier
fees and other plan terms. Compare the complete
current offers before switching.
Should I choose a fixed-rate electricity plan?
A fixed-rate plan can make the supply price
more predictable during the contract period.
However, the fixed rate may be higher than
ComEd's current or future supply price, so
customers should compare the complete offer.
Can I switch electricity suppliers in Joliet?
Eligible ComEd customers can generally choose
an alternative retail electric supplier for
the supply portion of their service. ComEd
continues to provide delivery service and
handles outages.
Why is my Joliet electricity bill higher in summer?
Electricity usage can increase during summer
because of air conditioning and cooling.
Your total bill depends on electricity
consumption as well as supply, delivery and
other applicable charges.
How do I find the cheapest electricity plan in Joliet?
Start with your ZIP code and typical monthly
electricity usage. Compare current supplier
offers with ComEd's Price to Compare and then
review the complete contract, monthly fees,
cancellation terms and renewable disclosures
before enrolling.
Joliet electricity pricing disclosure: Rates and plans displayed on this page are representative Joliet/ComEd market snapshots and can change frequently. Supplier rates may differ by ZIP code, usage, plan eligibility, promotional terms and contract. ComEd's Price to Compare is not the complete electricity bill because delivery and other applicable charges are separate. The lowest advertised cents-per-kWh rate does not necessarily represent the lowest total cost. Always review the current supplier disclosure statement and contract terms before enrolling.
