Electric aggregation program enrollment begins

May 1, 2017 – Oak Park’s electricity aggregation vendor will begin the enrollment process with mailings tomorrow to those customers who already participate as well as those who might want to join in the community program for the first time.

Electricity customers who receive a letter from Constellation Energy Services, but already participate in the Village’s aggregation program will be enrolled automatically after May 23, unless they choose to opt out by following the instructions in the letter.

Those electricity customers who use another power provider, but want to join the Village program, will need to follow the instructions in the letter and contact Constellation directly.

Aggregation does not alter the actual delivery of electricity, which is provided by ComEd. In fact, consumers have the option of choosing from scores of suppliers approved by the Illinois Commerce Commission. More information on providers is posted online at

The new Village contract will offer electricity at 7.179 cents per kilowatt hour for June through October, up slightly from the previous contract of 6.799 cents per kilowatt hour. The rate includes a fee of three-tenths of one cent that goes into a Village fund created to help support local renewable energy projects.

Oak Parkers enrolled in the current aggregation program, but who want to choose their own energy provider will need to mark and return the card provided in the Constellation letter. A ComEd account number or the code included in the letter is required to opt out.

More information on opting out or in is available by calling 1.877.549.6888 or visiting

Electricity aggregation, which was authorized by Illinois statute, allows municipalities to bundle residential and smaller business accounts, then use competitive bidding to seek lower rates from alternate suppliers. Voters gave the Village the authority to create a local aggregation program via referendum in 2011 and the first contract began Jan. 1, 2012.

Electricity customers who choose to opt out of the Village aggregation program will be enrolled automatically in electricity generation program provided by ComEd unless they select a provider on the open market.

Officials urge those who elect to choose an electricity provider from the state's list to read the fine print carefully. Contracts may contain unexpected fees and penalties to cancel.

The deadline to opt out or in to the Village aggregation program is May 23.
