Springfield, Illinois: why retail choice does not apply
Short answer. Springfield’s City Water, Light & Power is a municipal utility. CWLP customers do not use Ameren or ComEd retail choice. Springfield, Massachusetts is a different city and a different utility. Confirm the bill says CWLP before you stop shopping, and do not enroll an Ameren supplier on a CWLP account.
Streets on the edge of a city are often served by a neighboring utility, a municipal utility, or a cooperative. The utility name on the bill decides which offers exist. The city name does not.
The delivery utility and the supply decision
Springfield, Illinois is not a retail-choice shopping page. City Water, Light & Power is the utility, and a competitive supplier list written for a choice market does not apply. Confirm the utility name on the bill. If it is City Water, Light & Power, use that utility’s tariffs, budget billing, and efficiency programs. If the bill names a different, choice-eligible utility, follow that utility’s guide instead of this one.
Residential electric choice in Illinois applies in ComEd and Ameren Illinois territories. Municipal utilities such as Naperville and Springfield City Water, Light & Power are not that market. Plug In Illinois lists supplier offers against the utility price to compare. ComEd is in PJM; Ameren Illinois is in MISO.
What stays on the bill either way
Delivery charges from City Water, Light & Power pay for the local grid. They are not the supplier’s margin, and a supply switch does not remove them. Taxes and mandated riders also stay. The only piece you are testing is supply: the generation price, plus supplier fees, minus any credits that survive a careful reading of the contract.
National average prices are context, not a target. EIA reported U.S. residential average revenue of 16.5 cents per kWh for 2024 and 18.34 cents per kWh in June 2026. Those figures mix supply and delivery for the whole country. Your price to compare, basic service, or standard offer is a smaller supply number and is the one to beat.
How to run the comparison
- Read the utility name on the bill and confirm it is City Water, Light & Power. If it is not, stop and use the guide for the utility you actually have.
- Copy the default supply price (price to compare, basic service, standard offer, or SOS) and your typical monthly kWh.
- Open Plug In Illinois and filter to this utility or ZIP.
- Reject any offer that does not name City Water, Light & Power as the delivery company.
- Add monthly fees and decide whether an early termination fee is acceptable for the term.
- Enroll only with a supplier licensed under the Illinois Commerce Commission, and keep paying City Water, Light & Power until the switch date is confirmed.

Questions people ask
Who delivers electricity in Springfield, Illinois?
City Water, Light & Power is the delivery utility this guide is written for. Confirm that name on your bill, because municipal pockets and neighboring utilities use different rules.
Can I pick a supplier in Springfield, Illinois?
No. City Water, Light & Power customers are outside the retail-choice shopping model described on Power to Choose or a state REP list.

Use the bill, not a stale screenshot
Springfield, Illinois: why retail choice does not apply comes down to documents you can keep: the utility name on the bill, the supply price or default price, the kWh or demand that drove the charges, and the term and fees in any contract. National average prices from the Energy Information Administration are context. For 2024, EIA put average residential use at 865 kWh a month and the average residential price at 16.5 cents per kWh. For June 2026, EIA reported 18.34 cents per kWh of residential revenue. Those figures mix supply and delivery for the whole country. They are not a price to compare, and they are not an offer in this territory.
If a salesperson’s number and the bill disagree, keep the bill. Shop Energy Prices does not rank suppliers and does not publish a live rate table. Re-check the official shopping site or the utility tariff on the day you enroll, because offers and default prices change.
Going further on Springfield, Illinois: why retail choice does not apply
Springfield, Illinois: why retail choice does not apply is a local shopping problem only if the account is in a retail-choice territory and the account is in your name. The utility printed on the bill is the fact. The city name is a hint.
Where choice exists, you shop supply. Delivery, outages, and the meter stay with the utility. A supplier that does not name that utility is showing you the wrong product.
The benchmark is the price to compare, basic service, standard offer, or standard-offer service for that utility, not the national average. EIA’s 16.5 cents per kWh for 2024 and 18.34 cents of residential revenue per kWh in June 2026 mix supply and delivery for the whole country.
Offers change. This site does not rank companies and does not post a live table. On the day you enroll, read the contract term, the monthly fee, and the early termination fee at your own kilowatt-hours.
An illustration only: moving from 9 cents to 8 cents on 650 kilowatt-hours is 7 dollars before fees. A monthly fee or an early termination fee can erase it. Delivery does not disappear.
Addresses on the edge of a town, and addresses served by a municipal utility or a cooperative, often cannot use the investor-owned shopping site. If the bill and this page disagree, follow the bill.
What to verify before you act
Write down the utility name, the account name, the supply price or default price, and a typical month of use. Springfield, Illinois: why retail choice does not apply does not change those four facts. If a contractor, a supplier, or a city page disagrees with the bill, the bill wins. Shop Energy Prices does not sell electricity and does not keep a live rate table.
Use one official source for the benchmark: the price to compare or default service on the bill, the state shopping site if your state publishes one, or the commission docket that sets the default. EIA’s national averages are context for scale. They are the wrong number to beat.
Keep the contract PDF. Circle the term, the fee to leave, the renewal rule, and any pass-through that is not fixed. A verbal match to a competitor is not the product. If you are inside a cancellation window, follow the written notice method the same day and keep a copy.
