Champaign Electricity Rates: Ameren Price to Compare & Best Plans 2026
Champaign electricity rates jumped this summer, and the reason is not your utility. Ameren Illinois’ price to compare sits at about 11.33 cents per kWh from June 1 through September 30, 2026 — up from roughly 8.77 cents. The increase traces to a regional capacity auction, not a rate case, and Illinois’ retail choice law means you can shop the supply portion of your bill while Ameren keeps delivering the power.
TL;DR — Champaign electricity rates this summer
- Price to compare: ~11.33¢/kWh (Ameren Illinois, Jun 1 – Sep 30, 2026).
- Up from ~8.77¢ — a jump of roughly 29% for the summer season.
- The cause: the MISO capacity auction cleared at $666.50/MW-day, up about 2,122% year over year.
- You can switch suppliers. Ameren still delivers power and handles outages.
- Rates are seasonal — this summer figure resets on October 1.
- Students: start service 1–2 weeks before your lease begins.
What is the current price to compare for Champaign electricity rates?
Ameren Illinois’ residential price to compare is approximately 11.33 cents per kWh for the June 1 through September 30, 2026 period. For the first 800 kWh of usage, that figure is built from roughly 8.2¢ of supply, 0.308¢ of supply cost adjustment, and 2.765¢ of transmission.
The price to compare is the number a competitive supplier has to beat to save you money. You can confirm the current figure on Plug In Illinois, the official comparison site run by the Illinois Commerce Commission — worth using rather than a broker site, because it lists only certified suppliers and shows the terms in a standard format.
Why did Champaign electricity rates rise on June 1?
Because of capacity, not consumption. Capacity payments are what generators receive for guaranteeing they will be available on the highest-demand days — a kind of insurance premium the grid pays regardless of how much electricity actually gets produced.
MISO, the regional grid operator covering central and southern Illinois, ran a summer capacity auction that cleared at $666.50 per MW-day, against roughly $30 per MW-day the prior year. That is an increase of about 2,122%, and it flows into supply rates the following season. This is the single largest reason Champaign electricity rates moved, and it explains why neighboring Ameren territories saw the same jump at the same moment.
Two structural pressures sit behind that auction result: older generation retiring faster than replacements come online, and demand growing from data centers and electrification. The U.S. Energy Information Administration tracks state-level electricity prices over time if you want to see how Illinois compares nationally rather than judging from one bill.
What can you actually shop on your bill?
| Charge | Who sets it | Can you shop it? |
|---|---|---|
| Electric supply | Ameren default or your chosen supplier | Yes |
| Transmission | Regulated, passed through | No |
| Delivery / distribution | Ameren Illinois, ICC-regulated | No |
| Taxes and riders | State and local | No |
Only the first row is competitive. That is why a supplier promising to “cut your bill in half” is overselling — even an excellent supply rate leaves delivery, transmission, and taxes untouched.
What’s the best electricity plan in Champaign?
The best of the Champaign electricity rates offers is the one that beats 11.33¢ on a fixed term without hiding costs elsewhere. Four checks before signing:
- Fixed rate, stated term. Variable rates in a high-capacity-cost year are a genuinely bad bet.
- Watch the October reset. Because Champaign electricity rates are seasonal, an offer that looks strong against the summer price to compare may look ordinary against the winter one. Compare against the term you are locking, not today’s snapshot.
- No monthly fee, or a fee small enough that it does not cancel the per-kWh gain at your usage.
- Read the cancellation terms before a long lock. Flexibility has value when prices are moving this much.
Illinois also has an unusually strong consumer advocate in the Citizens Utility Board, which publishes independent analysis of supplier offers. If a deal seems too good, checking an independent source before enrolling is cheap insurance.
Setting up electricity as a U of I student
Champaign electricity rates matter most at move-in: Champaign-Urbana empties and refills on the university calendar, and August is the busiest connection month of the year. If you are moving into off-campus housing:
- Call 1–2 weeks before your lease start. Same-day connection is not guaranteed during move-in week.
- Budget for the summer rate. Arriving in August means your first bills land at the seasonal peak, before the October reset.
- Expect a deposit without established credit, and ask what alternatives exist.
- Decline door-to-door offers. Student neighborhoods see a spike in supplier canvassing every August; no legitimate offer requires an immediate decision.
- Schedule your move-out shutoff. Summer subleases are where forgotten accounts quietly accrue charges.

Lowering the bill when you cannot change the rate
Supply shopping is the fastest lever but rarely the biggest. The Department of Energy’s Energy Saver guidance puts heating and cooling at roughly half of a typical home’s energy use, which means summer thermostat habits often outweigh a one-cent supply difference.
In the older housing stock common around campus, the cheapest wins are usually mechanical rather than behavioral: sealing window AC units, blocking direct sun on west-facing windows in the afternoon, and clearing airflow around vents. None of it is glamorous, and all of it compounds across a hot Illinois August.
Shopping Champaign Electricity — Or Moving In?
Compare supply rates against the 11.33¢ price to compare before you lock a term — and if you are setting up a new place, line up internet at the same address in one sitting.

Illinois is split between two major utilities, and which side of the line you live on matters. Champaign sits in Ameren Illinois territory, which is served by the MISO grid. Northern Illinois, including Chicago, is ComEd territory on the PJM grid — see our Illinois electricity rates comparison for both sides. The two grids ran separate capacity auctions with different results, so the summer increases were not identical across the state.
That is worth knowing if you are comparing notes with friends elsewhere in Illinois, or if you moved to Champaign from Chicago. A supplier offer that was competitive on one side of the state is not automatically competitive on the other, because the benchmark it is measured against differs. When evaluating Champaign electricity rates, confirm the offer is quoted against the Ameren price to compare and not ComEd’s.
Municipal utilities add a third category. A handful of Illinois communities run their own electric utilities and do not participate in retail choice at all — residents there cannot shop supply regardless of what a marketer claims. Champaign is not one of them; retail choice applies here.
Three mistakes that cost Champaign households money
- Letting a fixed term expire into a variable rate. Most contracts roll to month-to-month variable pricing rather than renewing, and in a year with capacity costs this elevated, that is an expensive default. Diarize your contract end date the day you sign.
- Judging an offer against the wrong season. Champaign electricity rates reset October 1. A 12-month fixed offer should be compared against a full year of expected prices, not against the summer peak that happens to be in effect the day you shop.
- Enrolling from a door knock. Canvassing spikes in student neighborhoods every August. Ask for the terms in writing, then verify the supplier is certified on the state comparison site before giving anyone an account number.
If you believe you were switched without clear consent, the Illinois Commerce Commission accepts complaints and can investigate. Keeping the enrollment paperwork makes that process considerably easier.
