About Energy Choice in Peoria
Peoria's electric grid is part of Ameren Illinois's central Illinois delivery network, which serves roughly 1.2 million customers from Peoria south through East St. Louis. The delivery half of a Peoria bill — poles, wires, substations, meter reads, restoration crews — is Ameren's job under regulated rates set by the Illinois Commerce Commission. The supply half is the piece Peoria residents can shop.
Because Ameren Illinois sits inside MISO rather than PJM, wholesale supply prices in Peoria track a different market than Chicago's. A Peoria household deciding between the Ameren Price to Compare and a fixed retail contract is really deciding whether to accept the next MISO-driven PTC reset or lock a rate through it. That decision has moved a lot over the last few years as MISO capacity auctions have cleared unpredictably.
Local heating patterns shape the shopping math too. Peoria winters run cold enough that gas heat is dominant, but electric use for AC, appliances and increasingly EV charging is a real annual line item. Households with electric-heavy usage — heat pumps, well pumps, workshops — see the biggest absolute savings from a fixed 12- or 24-month Ameren-territory supply contract because more of their bill is exposed to the supply rate.
One thing that hasn't changed since deregulation: outage response. Ameren Illinois still owns every wire on every Peoria pole, and the 800-755-5000 outage line goes to Ameren whether you're on the Price to Compare or a third-party supply contract. Retail suppliers are billing entities, not utilities.

Frequently Asked Questions
Which utility serves Peoria?
Ameren Illinois is the electric utility for Peoria and most of central Illinois. Ameren owns the distribution system, reads the meters and handles outage restoration regardless of which retail supplier a household chooses.
What is the Price to Compare in Ameren Illinois territory?
It's the default supply rate Ameren Illinois charges Peoria customers who haven't shopped, set through Illinois Power Agency procurement cycles. Any competing supplier's fixed rate should be evaluated against the PTC that will actually be in effect over your contract term.
Is Peoria on the same wholesale grid as Chicago?
No. Ameren Illinois is in MISO while ComEd (Chicago) is in PJM. That's why Ameren's Price to Compare and ComEd's Price to Compare can move independently — Peoria's supply market is genuinely separate from Chicago's.
Do I have to notify Ameren Illinois when I switch suppliers in Peoria?
No. The new supplier files the switch electronically. Ameren continues to bill you and continues to deliver electricity — the only change is which company appears on the 'electric supply' line of your bill.
What if the power goes out in Peoria after I switch?
Call Ameren Illinois at 800-755-5000. Outage response is Ameren's responsibility across its central Illinois territory, and it doesn't change when a household picks a third-party supplier.
