Municipal Electric Aggregation


The Village renewed its contract with Dynegy at 7.101 cents/kwhr through October 2018.



Following the passage of a 2013 voter referendum by majority vote, the Village of Clarendon Hills contracted to procure lower-cost electric supply for residents and small businesses. The Village recently renewed the program with the lowest bidder, Dynegy Energy, at a fixed rate of 7.107¢ per kWh for a 13-month term from September 2017 to October 2018.

There is no enrollment fee to join, and no early termination fee to leave the program.

ComEd default rate Sep 2017 to May 2018:

7.122¢ per kWh

Clarendon Hills rate to October 2018:

7.107¢ per kWh

The ComEd rate will readjust in June 2018 while the Clarendon Hills rate will remain fixed through October 2018.

Notices will be mailed in July with a response deadline three weeks later. Residents who wish to remain in the program and receive an opt out notice need do nothing to be automatically enrolled. Anyone not receiving an opt out notice who wishes to enroll in the program may do so by calling Dynegy at 844-351-7691 asking for the Village of Clarendon Hills rate.

Again, all residents and small businesses will automatically be enrolled unless they:

  • Choose to opt out as directed in the opt out notice; or
  • Have previously switched to another alternative Supplier; or
  • Participate in an hourly-rate program

Ratepayers who wish to reduce their carbon footprint may contact Dynegy to opt in to energy supported by 100% Renewable Energy Credits (RECs) at the slightly higher rate of 7.301¢ per kWh. If no action is taken, ratepayers will receive the lower rate of 7.107¢ which offers a minimum of 13% RECs.

Please note: No one will ever come to your home or call to enroll you in the Village’s program. Should you receive such a call from a person purporting to represent the Village, Dynegy, or ComEd, take the solicitor’s information and contact the Illinois Commerce Commission at their Consumer Services Division complaint line: 800-524-0795.

1.       How can I enroll?

During the initial three-week opt out period, you need do nothing if you received an opt out notice; you will automatically be enrolled unless you opt out. After the initial opt out period, a ratepayer may enroll at any time by calling Dynegy at 844-351-7691 and asking for the Village of Clarendon Hills rate.

2.       What is an eligible resident or small commercial account?

Any resident who is currently with ComEd and has not already switched to an Alternative Retail Electric Supplier (ARES) or who is not enrolled in a special Residential Real-Time Pricing (RRTP) program is eligible, and small commercial accounts are eligible. You must also have a residence or business located within the Village limits.

3.       What is a “small commercial account?”

A small commercial account is a commercial account that consumes less than 15,000 kWh per year.

4.       What is the current ComEd default rate?

The base ComEd rate for September 2017 through May 2018 is 7.122¢ per kWh and includes a variable charge or credit, the Purchase Electricity Adjustment (PEA). For more information, visit

5.       Will I receive two bills, one from ComEd and another from the new supplier?

No. ComEd will continue to bill you for electric supply, delivery and taxes. ComEd delivers electricity, and will continue to bill you for that, but they no longer supply it. They will pass along the fees you pay for the supply of your energy to the new supplier.

6.       Whom do I call if I have service problems?

Always call ComEd with reports of outages or downed power lines at 800-334-7661. For questions about your supply, you can call the customer service number for Dynegy. This will be listed under “Electric Supply Services” on your ComEd bill.

7.       If I am automatically enrolled in the program, can I leave the program later?

Yes, you can vacate the program at any time move your account back to the default ComEd rate service, or to another Supplier. There is no early termination fee to leave.

8.       What is ComEd’s 6-month “hold” requirement?

Please note State Regulations: If you move from the program back to ComEd for longer than two months, your account is placed in a “bundled hold” status, and you may not return to the Clarendon Hills program until a full six months has passed.

9.       I am enrolled in low-income assistance program. Will that be affected?

No. If you currently receive assistance via PIPP or LIHEAP, that status will not change and you can continue to get these benefits for your ComEd bill.

10.   I’m on ComEd’s budget-billing plan. Will that change?

No. If you are currently on the budget-billing plan, you will remain on that plan.

11.   Can I still have my payment automatically deduced from my bank account?

Yes. The way you pay your ComEd bill will not change.

12.   Will someone come to my home or call to sign me up?

No. You need do nothing to automatically be enrolled in the program. If someone calls or visits your home claiming to be the Village’s power supplier, please file a complaint with the ICC at

13.   Is my electric supply at greater risk now that deregulation has opened markets to many new suppliers?

No. By law, ComEd remains the Provider of Last Resort (POLR), so if there is an issue with securing electric supply, ComEd is required to deliver, regardless.

14.   Is any of the energy generated from renewable “green” sources?

Yes. 13% of your energy consumption is sourced from renewable generation such as solar and wind that may be represented through the purchase of Renewable Energy Certificates (RECs). 13% is the minimum currently required by the Illinois Renewable Portfolio Standard.

Since implemented through a referendum in November 2012, electric aggregation has saved residents of Clarendon Hills over $625,000 in comparison ComEd Supply rates. Due in part to competitive pressure, ComEd has reduced rates and amended rate setting practice to allow for a more adjustable rate during the year. Now ComEd is allowed to float approximately $5 per kilowatt hour monthly above or below rate and is allowed two rate setting dates (one in October, one in June). This flexibility has allowed ComEd to undercut much of the municipal aggregation market, and many communities have returned to ComEd.
