Did you know?

The City receives a bulk electric supply rate that is available to residents and small businesses. This is called electrical aggregation. Crystal Lake has been providing the Electric Aggregation Program since 2012.

The City recently renewed the program and contracted with Dynegy Energy Services for a 24-month period from October 2018 to October 2020. There will be a fixed rate of 7.098¢ per kWh during this time.

There is no enrollment fee to join and no early termination fee to leave the program. You will continue to receive only one bill from ComEd for electric supply, delivery and taxes, with supply fees being passed along to Dynegy Energy Services.

Rates will be changed on the October meter read date for each resident or business and will be reflected on the November bill.

Notices were mailed to all residents and small business owners beginning August 10, 2018. Two types of notices were mailed:

  1. Opt Out Notices
    Opt Out Notices were mailed to all eligible City of Crystal Lake residents and small business owners who have electric supply service with ComEd or who are enrolled in the City's previous aggregation program. Ratepayers who received an Opt Out Notice were automatically enrolled unless they opted out by August 31. However, if you missed the initial opt-out period and wish to opt out, you may still do so by contacting if Dynegy Energy Services at (844) 351-7691. If you were previously enrolled with ComEd, and did not Opt Out, you should receive a notice in September from ComEd confirming that Dynegy is your energy supplier.
  2. Opt-In Notices
    Ratepayers not currently enrolled in Crystal Lake’s program, but who are enrolled with a supplier in their own private contract, will receive an informative, Opt In Notice. Those ratepayers will not be automatically enrolled, but do so by calling Dynegy at (844) 351-7691 and asking for the Crystal Lake rate. It is recommended that ratepayers opting in should check with their current contractor regarding early termination fees. You may still enroll at any time during the 24-month program by contacting Dynegy.

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

Frequently Asked Questions

  • How can I enroll?
    You will automatically be enrolled unless you opt out, have previously switched to an alternative supplier, or participate in an hourly program. After the initial opt out period, a ratepayer may enroll by calling Dynegy at (844) 351-7691 and asking for the Crystal Lake rate of 7.098¢.

  • What defines an eligible resident or small commercial account (commercial account consumes less than 15,000 kWh per year)?
    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 City limits.

  • Who should 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, please call the customer service number for Dynegy at (844) 351-7691. This number will also be listed under “Electric Supply Services” on your ComEd bill.

  • If I am automatically enrolled in the program now, can I leave the program at any time?
    Yes, you can later leave the program and move your account back to ComEd or another Supplier. There is no early termination fee to leave.
  • 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 Crystal Lake program until a full six months has passed.
  • 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.
  • 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.
  • Can I still have my payment automatically deducted from my bank account?
    Yes. The way you pay your ComEd bill will not change.
  • 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 City’s power supplier, please file a complaint with the ICC at http://www.icc.illinois.gov/consumer/complaint.
  • Is any of the energy in the Traditional Program generated from renewable “green” sources?
    Yes. 14.5% 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). All of the energy in the Renewable Power Program is generated from “green” sources such as solar, wind and water.
