City of Elmhurst Electric Aggregation Program

Following the passage of a March 2012 voter Referendum, the City of Elmhurst contracted to procure electric supply in a municipal electric aggregation program for residents and small businesses.

The City has continued to monitor the power supply market and recently was able to contract a program with ELIGO ENERGY IL, LLC whereby residents and small businesses will pay exactly the ComEd rate and 25% Renewable Energy Certificates (RECs) will be purchased for the City.  This program will position the City to be designated as an EPA Green Power Partner Community at zero increased cost to the residents!  The program is for a 24-month term starting with meter read dates in May 2021 and ending at meter read dates in May 2023.

The cost of serving each electric account varies greatly, depending on usage patterns. Some ratepayer accounts will be served by ComEd supply service and others will be switched to the new supplier, ELIGO ENERGY, and pay the exact same ComEd rate every month.  ELIGO ENERGY will purchase RECs for the City based on the historical usage for accounts on ELIGO ENERGY supply and ComEd supply. At times during the contract you may be switched between ComEd and Eligo Energy. You will still pay the same rate.

Residents in the Elmhurst Green Electricity Aggregation Program, whether receiving service from ComEd or from ELIGO ENERGY will pay the same rate. 

Why are some accounts at ComEd and some at Eligo Energy?

Suppliers analyze every meter; depending on complex usage patterns, certain accounts are selected to remain at ComEd and others switch to Eligo. The net effect is same for all: all pay the 

ComEd rate; for zero added costs, and Green Power is procured for both those served by ComEd supply, and those enrolled with Eligo. Additionally, the City will receive an annual civic contribution to support local sustainability initiatives  at zero added cost to residents and the City.


For more information, visit or call Eligo at 630-352-3470 Monday through Friday, 8am to 6pm.


No one from Eligo, ComEd, or the City will ever visit your home or call you to enroll. If a solicitor claims to be the City supplier, Eligo, or ComEd, take their information and report the incident to the ICC at Never reveal your ComEd account number or allow a solicitor to view your ComEd bill unless you are certain you wish to enroll with that supplier and have read all terms and conditions. Questions: Email or leave your name and callback number at 800-727-3820 and someone will reach out to you shortly.

The program is anticipated to reduce carbon emissions by more than 100,000 tons annually. RECs purchased for the City’s energy consumption will be sourced from wind power generators located in the Midwest and are Green-e certified.

This program enables the City to receive the designation of an EPA Green Power Partner Community. The U.S. Environmental Protection Agency lists the following benefits of attaining designation as a Green Power Partner Community:

  • Improved living and community environment
  • Reduced greenhouse gas emissions and other pollutants
  • Demonstrated civic leadership
  • Enhanced community image and increased citizen pride
