Community Choice Aggregation

Electrical aggregation, permitted through state statue, allows municipalities to seek alternate suppliers of electricity as a way to acquire lower rates for residents and business owners whose properties use fewer than 15,000 kWh per month. Aggregation does not alter the actual delivery of electricity, which still is provided by ComEd.

2014 Enrollment Period

The Village Board approved the aggregation program’s amended plan of operation and governance on March 17, 2014. An auction was held on April 10, 2014 to solicit bids from electricity providers. On April 11, 2014 the Village Board approved a contract with Constellation.

Information about the new contract and customer options was mailed to all all current aggregation customers. Aggregation participants have have until May 8, 2014 to choose one of the following options:

  • Easiest: Do nothing. You will be enrolled automatically in the Village’s base contract from Constellation Energy. At 7.47 cents per kilowatt hour, this is the most affordable option, but it is not green energy.
  • Greenest: Call 1.800.718.1493 to enroll in Constellation’s all-green energy option. This option, at 7.57 cents per kilowatt hour, will add about $1 to the average homeowner’s monthly bill compared to the base contract. You will need your ComEd account number. The call center is open from 7 a.m. to 7 p.m.
  • More Options: Opt out of the Village’s program and default to ComEd’s state-approved rate, or choose from a variety of suppliers at
