Utility Check

Switch Electricity Supplier in Illinois

ComEd and Ameren customers can choose their supplier, but Illinois is unusual — the regulated utility's default rate (ComEd's 'Price to Compare') is often very competitive thanks to bulk auctions. Always check whether switching actually beats the PTC before signing anything.

Average savings: $50–$300/year

How to switch in Illinois

  1. 1

    Look up ComEd or Ameren's current Price to Compare on your bill.

  2. 2

    Browse Plug In Illinois — filter for fixed-rate plans below your PTC.

  3. 3

    Verify there is no cancellation fee and no monthly fee.

  4. 4

    Watch out for variable rates that look low but reset every month.

Red flags to avoid

  • •Suppliers offering 'low intro rates' that triple after 3 months — this is the most common Illinois scam.
  • •Municipal aggregation programs that quietly switched you back to a higher-cost supplier.

Your delivery utility

When you switch suppliers, your delivery utility doesn't change — they still maintain the wires and respond to outages. Only the energy charge on your bill changes.
