Where to pay your Naperville electric bill

Naperville is served by Nicor Gas for natural gas and ComEd for electricity. If you live in Naperville, your electric bill comes from ComEd, which is the regulated utility for northern Illinois. You have one choice for your electricity supplier — ComEd — but you do have multiple ways to pay your bill each month.

You can pay ComEd online through their website at ComEd.com, by phone at 1-877-426-6331, by mail, or in person at authorized payment locations. Online payment is the fastest route: you can set it up in minutes and schedule payments in advance. If you pay by mail, send your check to the address printed on your bill — mail typically takes 7 to 10 days to arrive, so send it early enough that ComEd receives it before your due date.

ComEd also offers automatic payment through bank account deduction or credit card. This removes the risk of a late payment if you forget to submit it manually. You can enroll in automatic payment on ComEd.com or by calling their customer service line.

Key Takeaways

  • ComEd is your only electricity provider in Naperville, and you can pay your bill online, by phone, by mail, or through automatic bank deduction.
  • Your bill includes generation and delivery charges, and the delivery portion is regulated by the Illinois Commerce Commission.
  • ComEd offers budget billing, which spreads your annual costs evenly across 12 months so your bill stays roughly the same each month.
  • If you cannot pay your full bill, contact ComEd about payment plans or low-income assistance programs before your account falls behind.
  • You can reduce your bill by understanding time-of-use rates, fixing air leaks, and adjusting your thermostat when you are away.

Reading your ComEd bill and understanding the charges

Your ComEd bill has two main parts: the generation charge and the delivery charge. The generation charge is what you pay for the electricity itself. The delivery charge is what you pay ComEd to maintain the poles, wires, and equipment that bring that electricity to your home. The delivery charge is regulated by the Illinois Commerce Commission, which means ComEd cannot raise it without approval from the state.

Your bill also shows your usage in kilowatt-hours (kWh). One kilowatt-hour is the amount of electricity it takes to run a 100-watt light bulb for 10 hours. Your bill compares this month's usage to the same month last year, so you can see whether you are using more or less electricity than you did before.

Look for any riders or adjustments on your bill — these are extra charges or credits that ComEd adds for things like infrastructure improvements or fuel cost adjustments. These are separate from your base generation and delivery rates. If you see a charge you do not recognize, call ComEd at 1-877-426-6331 to ask what it covers.

Budget billing and payment plans

If your electric bill swings wildly from month to month — high in summer when you run air conditioning, low in winter — ComEd's budget billing program may help you plan ahead. Budget billing calculates your average monthly cost based on your usage over the past 12 months and spreads that amount evenly across 12 equal payments. This means your bill stays roughly the same each month instead of spiking in hot or cold weather.

Budget billing does not reduce what you pay overall — it just redistributes it. At the end of the year, ComEd reconciles your actual usage against what you paid, and you either owe a balance or receive a credit. You can enroll in budget billing on ComEd.com or by phone.

If you cannot pay your bill in full when it is due, ComEd offers payment plans that let you spread the cost over several months. Contact ComEd before your account becomes past due — the sooner you call, the more options you have. ComEd can also refer you to low-income assistance programs if your household income falls below certain thresholds.

How to lower your electric bill

Your generation charge depends on how much electricity you use, so reducing usage is the most direct way to lower your bill. Start by finding the biggest energy users in your home: air conditioning, heating, water heating, and refrigeration typically account for the majority of residential electricity use. Adjusting your thermostat by a few degrees when you are away or asleep can save 10 to 15 percent on heating and cooling costs.

Seal air leaks around windows, doors, and ductwork so your heating and cooling system does not have to work as hard. Replace incandescent light bulbs with LED bulbs, which use about 75 percent less electricity and last much longer. Unplug devices and chargers when you are not using them, or plug them into a power strip that you can turn off — many devices draw power even when they appear to be off.

ComEd also offers a home energy audit that identifies where your home is losing energy. You can request one on ComEd.com. Some audits are free; others may have a small fee. The audit report will show you specific upgrades — like insulation, weatherstripping, or HVAC maintenance — that could reduce your bill.

What to do if you receive a disconnection notice

If your account falls behind, ComEd will send you a disconnection notice before they shut off your service. The notice tells you how many days you have to pay before the disconnection happens. Do not ignore this notice — contact ComEd immediately at 1-877-426-6331 to discuss your options.

ComEd is required by Illinois law to offer a payment plan before disconnecting service. You can also ask about the Low Income Home Energy Assistance Program (LIHEAP), which provides one-time bill assistance to households that meet income limits. LIHEAP is administered through the City of Naperville's Department of Community Services, and you can reach them at 630-305-7600 to learn whether you may be may be able to access and how to apply.

If you are a senior citizen or have a medical condition that makes electricity essential, tell ComEd when you call. Illinois has additional protections for these households, including extended payment plans and restrictions on when disconnection can occur.

Comparing your bill to your neighbors and tracking usage over time

ComEd provides a usage comparison on your bill that shows how your electricity consumption compares to similar homes in your area. This comparison accounts for home size and weather, so it gives you a realistic benchmark. If your usage is significantly higher than similar homes, it signals that you may have an efficiency problem worth investigating.

You can also track your usage in real time through ComEd's online account portal or mobile app. This lets you see which days or times you use the most electricity, which can help you identify patterns. For example, if your usage spikes on certain days, you might discover that a particular appliance is running more than you expected.

Keep your bills for at least one year so you can spot trends. If your bill jumps unexpectedly and your usage has not changed, it could signal a problem with your meter or an appliance failure. Contact ComEd if you suspect a meter issue — they can test it at no charge.

Understanding ComEd's rate structure and when rates change

ComEd's rates have two components: the generation rate, which ComEd sets and can change, and the delivery rate, which the Illinois Commerce Commission must approve. The generation rate can change more frequently because it reflects the cost of fuel and wholesale electricity markets. The delivery rate is more stable because it is regulated.

ComEd typically files for rate changes with the Illinois Commerce Commission once per year. When a rate change is approved, ComEd notifies customers and the new rates take effect on a date specified in the order. You can find information about pending or approved rate cases on the Illinois Commerce Commission website at icc.illinois.gov.

Your bill will show the effective date of any rate change. If you want to understand how a rate change affects your specific bill, you can calculate it: multiply your usage in kilowatt-hours by the new generation rate and the new delivery rate, then add any riders or adjustments. ComEd's customer service team can also walk you through the calculation if you call.

Frequently Asked Questions

Can I choose a different electricity supplier in Naperville?

No. Naperville is in ComEd's service territory, and ComEd is the only supplier. Illinois law allows some customers in other parts of the state to choose alternative suppliers, but that option is not available in northern Illinois. You can only choose how you pay ComEd and whether you enroll in programs like budget billing.

What happens if I pay my bill late?

ComEd charges a late fee if your payment arrives after the due date shown on your bill. The fee is a percentage of your bill balance. If your account remains unpaid for 30 days or more, ComEd may disconnect your service. Contact ComEd before you fall behind to discuss a payment plan.

How often does ComEd read my meter?

ComEd reads most residential meters once per month. If you have a smart meter, ComEd can read it remotely. If you believe your meter has been read incorrectly, you can request a meter test by calling 1-877-426-6331. ComEd performs the test at no charge if the meter is found to be inaccurate.

Does ComEd offer any discounts for seniors or low-income households?

ComEd does not offer a direct discount, but Illinois residents who are seniors, disabled, or low-income may be may be able to access for the Low Income Home Energy Assistance Program (LIHEAP). Contact the City of Naperville's Department of Community Services at 630-305-7600 to learn more about this program and how to apply.

Can I set up automatic payments without a bank account?

ComEd's automatic payment option requires either a bank account for direct deduction or a credit or debit card. If you do not have either, you can still pay online using a prepaid card, or pay by phone with a card. You can also mail a check or pay in person at authorized payment locations.
