What is it?
A change in law in January 2010 allows
residents and small businesses in a community

to seek lower prices for electric supply.
What are the benefits?
The key benefit is the opportunity to achieve savings
in the cost of electricity supply.
Other advantages are that the price of electricity is fixed
for the duration of the contract and that certain costs, like
fuel adjustment charges not included in the default supply price,
are included in the electric aggregation price.
What if the initial price is higher than the utility’s?
The municipality is not obligated to accept a proposed price.
How long would the supply price continue?

How does a municipality establish a municipal electric aggregation program
for its residential and small business constiuents?

the community may seek lower prices for their electric supply.

programs where companies are calling me to sell me electricity over the

A small business that uses 15,000 kilowatthours or less per year is eligible.

Yes. The term “municipality” refers to units of government including cities,
villages, unincorporated areas of counties, and townships.

ordinance to place the issue on the ballot. Then the county or township’s
residents vote on whether to accept it.

of a regulated utilitiy who live in a city that is within the county eligible?

How does one enroll in a municipal electric aggregation program?
Residential and small business constitutents in communities whose voters
have passed a referendum to approve electric aggregation are enrolled
automatically. No one, however, is obligated to participate. Residents may
“opt out” for any reason and without penalty or cost.
Will a new resident of the municipality be eligible to participate?
Yes, and enrollment can be accomplished in three steps:
1. Sign up for service with Ameren
2. Obtain your Ameren account number.
3. Then call the municipality’s electric supply provider.

Yes, by simply following the steps above.
Will I have to participate?
No. You have a legal right to opt for any reason and at no cost or
How does one opt out?
Both the supplier and Ameren notify every eligible resident and small
business by letter of their right to opt out and indicate ways to do so,
including a toll-free number to the supplier’s customer service desk.
Does that mean one would be able to remain with Ameren?
Will I be penalized if I opt out?
Will I be able to join if I already have a contract with an alternate supplier?
Yes, but you will want to check your contract to make sure you would
not be subject to a fee for cancelling your contract early.
If I am with an alternate supplier, will I be switched to the municipal program?
No. Your account will not be included on the eligibility list to avoid the
risk of an early cancellation fee. You will have the choice to enroll,
however, if you wish.
Will I get two bills if we get a different electricity supplier?
Normally not. You will want to check with your municipality to find out
how billing will be handled under your program.
Who will I call if I have a question about the bill?
You will continue to call Ameren’s toll-free number for service and billing
Whom will I call if my power goes out or for other service problems?
You will call Ameren, which continues to provide distribution services
in the municipality.
Will I risk poorer service from Ameren if I opt out?
No. Standards by law and regulation for the quality of Ameren’s service
does not change.
Will I be hurting my delivery company by switching?
No. Ameren provides distribution service only. Any electricity it delivers
within the community is provided by the Illinois Power Agency.
Will the delivery company raise rates if too many people switch?
No. Again, Ameren does not supply power, so a change in the electric
supplier will not affect Ameren’s rates.
What will the rate be?
That is determined by bid from qualified electric suppliers.
How will I know what the rate is before the program begins?
The new supplier will notify each resident and small business customer
by letterof the bid price to compare and terms and conditions.
That correspondence also will provide information about how to opt out
for any customer who wishes to do so.
How long will the contract be for?
The duration will be determined in the bid. Suppliers usually propose rates
for contracts of various durations.
Will the fixed price last the entire term of the contract?
What will be included in the price?
Included are the supply of electricity, transmission, and related charges
What happens if bids come in higher than the current default price?
Municipalities are not required to accept bids and may reject them.
