Check Aurora’s municipal aggregation program
Aurora’s official electric aggregation page describes a program for eligible residents and small businesses. As reviewed in September 2026, the city lists MC Squared Energy Services (mc2) and a supply price tied to ComEd’s published monthly tariff supply rate through December 2027.
A rate that tracks ComEd is not a fixed cents-per-kWh price for the whole term. Read your latest city notice and supplier terms, and check the name on your bill to confirm whether you participate. ComEd continues billing and handling delivery and outages under the city program.
Use the ComEd benchmark that matches your service
The Illinois Commerce Commission publishes the ComEd Price to Compare. It combines electric supply and transmission charges and excludes the Purchased Electricity Adjustment. That makes it a supply-shopping reference, rather than the cost of your entire electric bill.
If you use ComEd hourly pricing, review the actual supply costs and usage on your bills. A flat benchmark alone does not describe an hourly account. Keep the service type, comparison period, and fees consistent when you review another plan.
Review a separate supplier offer before leaving your current plan
Use Plug In Illinois to explore the available choices for your utility area. Write down the new price, whether it is fixed or variable, the term length, monthly charges, and renewal terms. Compare those terms with your current arrangement, including any city aggregation notice.
For example, a $5 monthly supplier fee adds the equivalent of 1¢/kWh at 500 kWh of usage. A lower advertised energy rate can lose its advantage after that fee. The Illinois guide provides broader service-area context, and the app helps you keep track of a plan’s renewal date.
Aurora electric rate FAQ
Why might mc2 appear on my Aurora electric bill?
It may reflect participation in Aurora’s municipal aggregation program. Compare the supplier name and terms on your bill with your latest city notice to confirm your enrollment.
Is Aurora’s aggregation price fixed for the full contract?
The city program reviewed in September 2026 ties its supply price to ComEd’s published monthly tariff supply rate. That is different from locking in one cents-per-kWh price for the full term.
Does a different supplier replace ComEd delivery?
No. For an Aurora home served by ComEd, a supplier choice changes electricity supply. ComEd remains responsible for delivery service.
