Rockford electricity guide

How to choose the best electricity plan
Rockford electricity shoppers should not choose a supplier based only on the advertised cents-per-kWh rate. Compare the complete supply price, monthly fees, contract terms and ComEd's current Price to Compare.

500 kWh
Lower-usage household
Apartments and smaller homes may use less electricity than the standard 1,000-kWh comparison level. Monthly charges can have a larger impact at lower usage.
1,000 kWh
Standard comparison level
Many electricity offers are presented using 1,000 kWh as a comparison point. Your actual Rockford usage may be higher or lower.
Winter
Heating can change usage
Electricity usage can vary considerably depending on whether your home uses electric heat, natural gas or another heating source.
Summer
Cooling affects demand
Air conditioning can increase electricity consumption during hot Rockford summer periods.
Understand your bill
What determines your Rockford electric bill?
Your electricity supplier is only one component of your total 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 customers may receive supply service from ComEd or an alternative retail electric supplier.
ComEd delivery
ComEd operates the electric distribution system serving its territory. Delivery charges continue to apply when a customer chooses an alternative supplier.
Transmission and adjustments
ComEd's Price to Compare includes supply and transmission components. Other adjustments and delivery charges can affect the final bill.
Before you switch
Five things to check before choosing a plan
Compare the supplier's effective price against ComEd's current Price to Compare.
Check whether the offer is month-to-month, 3 months, 6 months, 10 months, 12 months or longer.
A plan with a lower cents-per-kWh rate can still cost more if it includes a recurring monthly charge.
Determine whether you will owe a fee if you cancel before the contract expires.

Rockford electricity FAQ
Frequently asked questions
Important things to know before switching electricity suppliers in Rockford.
Who are the best electricity providers in Rockford?
The best supplier depends on your ZIP code,
electricity usage, preferred contract length,
rate structure and budget. Rockford customers
in the ComEd service territory may compare
ComEd supply service with offers from
alternative retail electric suppliers.
What is the ComEd electricity rate in Rockford?
ComEd's summer 2026 Price to Compare is
10.399 cents per kWh. This is a supply and
transmission benchmark and is not the
complete delivered electricity bill.
What is the cheapest electricity rate in Rockford?
Recent Rockford market listings include a
7.49 cents-per-kWh variable offer and a
10.10 cents-per-kWh introductory offer,
along with fixed plans around 11 cents per
kWh and higher. These rates can change and
should not be treated as guaranteed future
prices.
Does Rockford have deregulated electricity?
Illinois has a competitive electricity
supply market. Eligible customers in the
ComEd service territory can generally choose
their electricity supplier while ComEd
continues to provide regulated delivery
service.
Does ComEd choose my electricity supplier?
ComEd provides electric delivery service
within its territory. Eligible customers
may choose who provides their electricity
supply, including ComEd or an alternative
retail electric supplier.
Is a low cents-per-kWh rate always cheapest?
No. A supplier's advertised rate may be
fixed, variable or introductory. Compare
the effective supply cost, monthly charges,
contract length and cancellation provisions.
Should I choose a fixed-rate electricity plan?
Fixed-rate plans can make the electricity
supply price more predictable during the
contract. You should still compare the
complete offer and understand any early
termination fee.
Can I switch electricity suppliers in Rockford?
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 Rockford electricity bill higher in summer?
Electricity usage can increase during summer
because of air conditioning and cooling.
Your total bill depends on consumption as
well as applicable supply and delivery
charges.
How do I find the cheapest electricity plan for my Rockford home?
Start with your ZIP code and typical monthly
electricity usage. Compare available supplier
offers with the current ComEd Price to Compare,
then review the complete supplier contract and
disclosure documents before enrolling.
Rockford electricity pricing disclosure: Rates and plans displayed on this page are representative 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.
