Bolingbrook electricity after a 2025 rate headline expires

Bolingbrook households that want a lower generation charge test a licensed offer against the ComEd price to compare for the current period, not against a headline that still says 2025. ComEd delivers the power, reads the meter, and answers outage calls. A supplier, if you enroll one, replaces only the supply portion of the bill. Plug In Illinois is the public list that sets those offers beside the ComEd benchmark for this territory.

Why a year printed in a title is not a price

Older shopping pages froze a season’s cents into the address of the article. Those figures are not a contract you can sign, and they are not ComEd’s price to compare for the bill cycle you are in. Suppliers revise offers. The utility benchmark moves on a posted schedule. A screenshot from a move, a group text, or a door hanger from a prior winter fails both tests: the term may be over, and the product may not even be a ComEd product.

Treat “2025 rates” as a retired label. The living comparison is this month’s statement plus the offer document you would actually enroll. If a website still ranks companies by a number captured in 2025, skip the ranking. This site does not score suppliers and does not keep a live Bolingbrook rate board.

Which Bolingbrook accounts can leave default supply

Residential choice in Illinois applies on ComEd and Ameren Illinois accounts. Bolingbrook delivery is ComEd, in the PJM region. Ameren Illinois is in MISO and publishes a different price to compare. An offer built for an Ameren premise will not sit on a ComEd meter, even when the supplier brand is familiar from a downstate advertisement.

Municipal electric systems sit outside that model. Naperville, a nearby suburb, runs its own municipal utility. Springfield City Water, Light and Power is another municipal system and does not use the Plug In Illinois residential list. A Bolingbrook street address is not those utilities. The bill header is the test. If the statement does not name ComEd, stop and follow the company that is printed. A border block can be served differently than the rest of town, and the city name will not fix the mismatch.

You can change supply only when the account is yours. If a landlord or a condo association is the customer of record, the occupant cannot enroll a supplier for that meter. Renters who pay ComEd in their own name can shop. Renters who pay a flat amount inside the rent cannot.

What moves on the statement, and what never does

A ComEd statement splits supply from delivery. Delivery covers local wires, metering, and outage response. Taxes and riders the regulator ties to delivery remain after a switch. The supplier does not become the company you phone when a storm drops the lights.

Supply is the generation piece under test. On default service it is ComEd’s price to compare. On a competitive product it is the supplier’s price, plus any monthly fee, minus a credit the contract actually pays at your usage. National all-in averages are a different object. The Energy Information Administration 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 blend supply and delivery for the whole country. They are context for scale. They are not the ComEd number a Bolingbrook offer has to beat.

How the offer appears before and after enrollment

Before you enroll, Plug In Illinois shows the supplier, the rate structure, the term, and the utility. Stay on the ComEd filter. A row that names Ameren is another market. The contract behind the row should restate the cents or the formula, the length in months, any early termination fee, and the rule for the day the term ends. A fixed supply price holds the generation rate. It does not freeze ComEd delivery charges, which can change under Illinois Commerce Commission orders.

After a completed switch, a later ComEd bill should name the supplier on the supply line. The change usually waits for a meter-read cycle. It is not an instant handoff on the afternoon you click enroll. Keep paying ComEd. The utility often remains the single biller, with the supplier’s charge inside that statement. If a second company starts mailing a separate supply invoice, read both so you do not pay generation twice or miss one of the two.

A pass that uses your kilowatt-hours

Copy kWh from your own recent statements, not from a neighbor and not from a national average. EIA’s 2024 figure of 865 kWh a month for residential customers is countrywide context, useful only as a reminder that a townhouse and a detached house diverge. Write down a heavy month and a typical month from the ComEd history.

Then put the arithmetic in one place. This is an illustration, not a Bolingbrook tariff and not a ComEd posting. Suppose the account uses 900 kWh and the price to compare is 8 cents per kWh. Supply at that benchmark is 900 times 0.08, or $72. A supplier at 7.2 cents is $64.80 before fees, a gap of $7.20. A monthly fee of $6.95 leaves about a quarter dollar, which is not a reason to accept a cancellation penalty. Change any input and the result moves. The illustration exists so the fee is visible.

Pick the term after the arithmetic. A 12-month fixed product helps only if you expect to stay through it. If a move is likely, weigh the early termination fee against the monthly gap you just computed. Read how early termination fees work before you lock a long term. Also read the renewal rule: many fixed products roll to a variable price you did not re-shop. Put a reminder on the calendar for the month before the end date.

Enroll only with a supplier the Illinois Commerce Commission licenses. The public list is Plug In Illinois. A clipboard at the door is not a license. Statewide structure is in the Illinois choice guide, and the comparison habit is on how to compare energy rates. The benchmark itself is explained in price to compare.

Errors that wipe out a small supply gap

Shopping an Ameren price, or a Texas retail price, because the cents look lower will not place that product on a ComEd meter in Bolingbrook. Comparing a supplier’s supply rate with the entire ComEd bill, delivery included, and calling the supplier “half the cost” is the same kind of mismatch. Delivery does not leave. A monthly fee on a small account is the next trap. A few hundred kWh can lose to a fee that a large house would barely notice.

Stacking is another failure. If a supplier is already on the account, a new enrollment replaces that supply. It does not add a second generation charge you can ignore. Read whether a cancellation fee is still in force. An enrollment you did not authorize is a separate problem, often called slamming. Do not treat a welcome letter as proof you agreed. The learning center’s slamming explainer describes that pattern. Finally, do not stop ComEd payments because a salesperson said the supplier “took over the account.” Delivery never transferred.
