About Energy Choice in Champaign
Champaign — home of the University of Illinois — is in Ameren Illinois territory, which covers most of central and southern Illinois. Ameren is a combined electric-and-gas utility for Champaign, so the same company delivers both fuels and sends one consolidated bill even when supply is shopped from a competing provider.
For electric supply, Ameren Illinois's default rate is set through auctions procured by the Illinois Power Agency and posted as a Price to Compare. Because Champaign is inside MISO rather than PJM, the wholesale price signals driving Ameren's PTC can look very different from ComEd's on any given month — a good reason not to assume a Chicago-market fixed rate is also a good deal in Champaign.
Champaign also has an active history of municipal electric aggregation. The city has previously negotiated group supply contracts on behalf of residents who didn't opt out; individual households are still free to pick their own Alternative Retail Electric Supplier at any time. If you're currently on the aggregation rate, benchmark it against both Ameren's Price to Compare and the fixed offers available for your ZIP.
On the gas side, Ameren Illinois runs a natural gas Choice program too, letting Champaign households pick a certified gas supplier while Ameren continues to move the fuel through its pipes and respond to emergencies.
