Ameren Illinois runs on MISO, not PJM. ComEd runs on PJM. They are separate utilities with separate grid operators and separate rate structures — a ComEd figure does not apply to an Ameren bill or the reverse.

Three reasons a bill jumps

The rate changed

Filed rate changes are public and dated. The current ones for Ameren Illinois are in the table above. Most of the recent regional increases have landed in delivery and transmission, which you cannot shop away by switching suppliers.

Your usage changed

Air conditioning, electric heat, an EV or a heat pump can move consumption 30–50% without anything else changing. Compare kilowatt-hours against the same month last year, not dollars — dollars move with the rate.

The billing period was longer

A 34-day cycle against a 28-day one is 21% more energy at the same daily usage. Check the service period dates before assuming a rate rise.

What to do about it

In order of how much they move the number: reduce the kilowatt-hours you buy, shift usage into cheaper hours if you are on time-of-use, and generate your own. Solar addresses the third and it only makes sense once you know your real rate and your real usage.

Common questions

Why is my Ameren Illinois bill so high?

Three things move it: the rate, your usage, and the length of the billing cycle. Compare kilowatt-hours to the same month last year first — dollars move with the rate, kilowatt-hours are the actual quantity.

How much is Ameren Illinois per kWh?

About 11.3¢ — Price to Compare — supply plus transmission, before delivery. Divide your bill total by kWh used for your own all-in figure.

Will solar eliminate my bill?

No. You keep a fixed customer charge and you still draw at night. Solar reduces how many kilowatt-hours you buy, which is a different thing from a zero bill.
