Frequently Asked Questions

Is ComEd Hourly Pricing worth it?

Hourly Pricing can save 10-15% if you can shift usage to off-peak hours (typically overnight and early morning). However, prices can spike during extreme weather, so it's best for customers with flexible schedules.

Should I switch from ComEd to an alternative supplier?

It depends on current market conditions and your risk tolerance. Fixed-rate plans offer price stability, while ComEd's default rate fluctuates. Compare current offers on PlugInIllinois.org to see if switching makes sense.

What happens if my alternative supplier goes out of business?

You automatically return to ComEd's default supply rate with no interruption in service. ComEd always delivers your electricity regardless of your supplier.
