Participants will continue to receive only one bill from ComEd, which will include the electricity supply charges from Dynegy. ComEd will continue to deliver power and respond to any disruptions in service. Residents and businesses will continue to make payments directly to ComEd.

Program History

In 2012, Hoffman Estates voters approved a referendum allowing the Village to create an electricity aggregation program on behalf of residents and businesses to reduce electricity costs. The Village, through its consultant, the Northern Illinois Municipal Electric Collaborative (NIMEC), solicited and reviewed proposals from several electricity suppliers certified in Illinois. For years 2012 through July 2014, FirstEnergy Solutions was the supplier. As of August 1, 2015, Constellation Energy is the electric supplier through August 2016 with a rate of 6.97¢/kWh. Dynegy Energy became the electric supplier for program participants in August 2016 through August 2017. ComEd still provides delivery and billing for electric service.

General information

Overview – What is municipal aggregation of electricity?
An electricity aggregation program allows municipalities to pool residential and small commercial retail customers together for the joint purchase of electricity. By creating these economies of scale, a community can leverage the buying power of thousands of residents and small businesses in an effort to obtain a lower price for the supply of electricity.

There are two main components to electricity: supply and distribution.  The supply of electricity is currently generated by ComEd at power plants.  Electricity is then transmitted and distributed to homes and businesses through ComEd's infrastructure and power lines.  With aggregation, a muncipality can seek a lower price for the supply of electricity with alternative suppliers other than ComEd; however, ComEd would continue to distribute electricity to consumers through its infrastructure.  Therefore, ComEd would continue to send out electricity bills and be contacted for service needs.  Please read the below description and reference the attached FAQs for more information.

Legislation – Why is this possible?
In 2009, the state of Illinois amended the Illinois Power Agency Act with Public Act 96-0716 to deregulate the electric market and provide for the municipal aggregation of electricity. Through deregulation, ComEd is no longer the only company that supplies electricity, but continues to provide power generated by others through its distribution system.

Process – How does it work?
In order for the Village to create a municipal aggregation program, a referendum must be approved by a majority of voters. The Village Board approved a resolution at the Dec. 5, 2011, Village Board meeting providing for the referendum question to appear on the ballot on March 20, 2012. The referendum asked:

"Shall the Village of Hoffman Estates have the authority to arrange for the supply of electricity for its residential and small commercial retail customers who have not opted out of such program?"

After referendum approval, the Village created a Plan of Operation and Governance, and held two public hearings to discuss this plan. Once the plan was in place, the Village solicited proposals and bids from suppliers who are licensed as alternative retail electric suppliers (ARES) in the state of Illinois. Bids were reviewed, and the Village determined if and who it would enter into an agreement with for energy supply. If favorable pricing does not exist, the Village will not enter into an agreement, and remain with ComEd.

Impact – How will this affect me?
All residents and small businesses will be automatically enrolled in the program unless they "opt-out." Before the next cycle of the aggregation program begins, all residents would receive notice to opt out of the program.

Regardless of whichever option residents and businesses chose, ComEd remains the utility provider delivering electricity to homes and businesses. Residents would continue to receive a ComEd bill and would continue to call ComEd in case of an outage or service need. The only difference would be a change in the supply rate of the electricity bill.

Municipal aggregation programs have been active in Ohio for several years, and are now spreading across Illinois. Over 20 Illinois municipalities passed referenda on the April 2011 ballot to begin the aggregation process (see attached list of communities). Additional communities, drawn by lower supplier pricing, put referenda on later ballots to continue in the process of establishing a municipal aggregate program with the hope of providing savings for residential and small business consumers. When aggregation agreements come to an end, the Village Board determines whether the Village will continue with its aggregation program, based on a variety of factors. An update to the aggregation program information will be made in summer 2015.
