City of Zion Electric Aggregation
Background: Following the passage of a 2012 voter Referendum, the City of Zion has managed an electric aggregation program. The average participating resident has enjoyed savings on their ComEd bills for years.
The City has again contracted with Chicago-based MC Squared Energy Services (MC2) for 12 months through August 2025 in a ComEd Price Match electric aggregation program. The rate is exactly the ComEd rate—guaranteed—so no resident will ever pay more than the ComEd rate.
The new ComEd base rate has declined to 6.72¢ per kWh, plus a monthly variable portion called the Purchased Electricity Adjustment (PEA). To view the current ComEd rate, visit www.ilagg.com/comedrate.
Residents in Zion’s aggregation program pay exactly the same rate (including the PEA) as ComEd supply customers. There is no enrollment fee and no early termination fee if residents leave the program.
Notices were mailed to ratepayers on June 18, 2024. All residents can choose to participate or remain with ComEd. In all cases, the rate remains identical to ComEd’s.
How to Opt Out: Return the enclosed postage-paid card, visit www.mc2energyservices.com/municipal-aggregation/optout, or call (312) 751-2202.
2. “Electric Aggregation Program Opt In Notice” — Your account remains unchanged, but you may contact MC2 to enroll. There are no termination fees by law.
3. “Informational Content Only” — Your account remains unchanged; no action is needed.
4. “Informational Notice: Return to ComEd Supply Service” — You are currently enrolled with MC2 and will return to ComEd. You need take no action. All accounts still pay the same rate.
Program Benefits:
- Zero rate risk — residents never pay more than ComEd’s rate.
- No hidden fees or early termination charges.
- Join or leave the program anytime at no cost.
- City receives a civic contribution at zero added cost.
No one from MC2, ComEd, or the City will ever visit or call to enroll you. Report false solicitations to the Illinois Commerce Commission at www.icc.illinois.gov/complaints. Never share your ComEd account number unless you fully intend to enroll and have reviewed all terms.
Electric Aggregation Program FAQs
1. How can I enroll?
During the initial three-week opt-out period, do nothing if you received an opt-out notice; you’ll automatically be enrolled unless you choose to opt out.
2. I switched to another supplier but want to join this program. How?
Call MC2 at (833) 811-0298, Mon–Fri 8am–5pm, and provide your ComEd account info. Illinois law forbids suppliers from charging termination fees.
3. Will I get two bills?
No. ComEd will continue billing for supply, delivery, and taxes. ComEd delivers your electricity, while MC2 supplies it behind the scenes.
4. If I’m automatically enrolled, can I leave later?
Yes—there are no termination fees.
5. Does this affect low-income assistance programs (PIPP or LIHEAP)?
No, your benefits are unaffected.
6. Does this impact my Community Solar enrollment?
No, community solar credits remain separate and unaffected.
7. What if I move?
If you stay within Zion, call MC2 to re-enroll at your new address. New residents may join by calling (833) 811-0298.

What do I need to do?
Nothing if you received an enrollment notice—you’ll automatically switch to MC2 at the ComEd rate unless you opt out.
