What they credit you
Exports offset supply charges only, never delivery, since 2025
Published termsComEd customers who began net metering on or after 1 January 2025 are credited for exports only against supply charges, never against delivery charges. On Rate BES, net exports earn kilowatt hour credits against the Electricity Supply Charge, Transmission Services Charge and Purchased Electricity Adjustment that can carry forward for the life of the system, or you can elect a monthly money credit at those three charges: 8.413 + 1.690 − 1.551 = 8.552 cents a kWh on a residential October 2026 bill, and the adjustment changes monthly. On time-of-use Rate BEST or hourly Rate BESH the credit is money at those time-varying supply prices. Customers already in the older classes before 1 January 2025, and later customers at the same premises, also get credit against per-kilowatt-hour delivery charges for the life of the system, as long as they keep meeting that class's rules (NM1 requires Rate BES) and no DG rebate was paid on the system.
- Month to month
- On Rate BES, kilowatt hour credits "accrue throughout the lifetime of the Eligible Facilities" (the tariff applies this from the October 2022 billing period). They stay with the billing address when a new customer takes over the home. They expire after a gap in ownership of the address longer than one calendar year, and they "will not transfer when there is a change in NM classification", such as a move to the monthly money credit, Rate BEST or a retail supplier. Legacy pre-2025 credits expire at the end of the annual period, which ends with the April or October billing period as you elect, and legacy NM1 energy credits also expire if you leave Rate BES.
- Once a year
- Kilowatt hour credits under the post-2025 Rate BES class are not cashed out; they carry forward. If you receive a money credit, such as the monthly money credit option, the tariff effective 14 September 2026 lets you elect to have a net credit balance on a monthly bill paid to you on or before that bill's due date, or by the next due date if your request comes too late to process. Legacy pre-2025 customers keep a 12-month annual period, and unused credits expire at its end.

These are real companies operating in ComEd territory. Bold Energy is listed first because it is the company we introduce first. That order is our choice, not a score. The other companies are ordered by reviews, years trading and BBB grade. None of them pays us for placement. Pick the one you want and we will call you to arrange it.
Ordering combines three things we read from primary sources: Google review count and rating, years trading taken from the company’s Better Business Bureau profile rather than its own marketing, and its BBB letter grade. BBB accreditation is shown but never scored, because it is a paid membership rather than a mark of quality.
Check any contractor license yourself at the state register. Do that before you sign anything, with any company, including ours.
What this looks like on a ComEd bill
An average Illinois household, against a system sized to cover its year. The energy charge is the part that goes to zero. The fixed monthly charge underneath it is the part that never does, and it is the number that decides whether a system pays for itself.
Meter reading falling from 41926 to 41733 kilowatt hours. A 693 kilowatt hour month against 886 kilowatt hours produced leaves 0 kilowatt hours billed and 193 banked for next month, so the energy charge falls from $137.84 to $0.00 at 19.89 cents per kilowatt hour.
Illinois average household use, 693 kWh a month, at the current published residential price of 19.89¢ per kWh. Your utility still bills a fixed monthly customer charge that no system offsets, so this is the energy part of the bill, which is the part that goes away.
Battery backup is mandatory
in ComEd territory.
ComEd does not credit the power you send back at the rate it charges you to take it.
That does not make solar a bad idea in ComEd territory. It changes what you should build. When exports are worth a fraction of retail the credit stops being the return, and the job becomes using more of your own production inside the house, which usually means a larger array than a one for one utility would need.
Sizing is where that gets decided, so ask about it directly. Illinois now credits new systems’ exports against supply charges only, so exports no longer reduce delivery charges. That makes using your own production inside the house worth more than exporting it. ComEd sets its own limits. Ask ComEd what it allows before you accept that a bigger system is off the table.
A battery then does two separate jobs. It moves daytime production into the evening so you use it instead of selling it, and it keeps the house running when the grid goes down. That second job is not a bonus. Panels on their own shut off in an outage, by design, so a roof full of them powers nothing during a storm. That is the part we will not refer around.
So we treat it as a requirement, not an upgrade. We will not refer you for a panels-only system in ComEd territory, and you should be skeptical of anyone who quotes you one without raising storage first.
Our referral policy, not a legal or utility requirement
What your installer should be telling you
Get ComEd to confirm in writing which net metering class you will be in, because banked kilowatt hour credits "will not transfer when there is a change in NM classification", including a switch to the monthly money credit, Rate BEST or a retail supplier. A battery interconnected on or after 1 June 2026 must stay on a time-of-use or hourly supply product such as Rate BEST or Rate BESH, so the Rate BES kilowatt hour credit is not available with it. If you began net metering on or after 1 January 2025 and buy supply from a retail electric supplier, ComEd pays no export credit, so get the supplier's terms in writing. If you have pre-2025 solar, taking ComEd's $300 per kW DC Resource 1 DG rebate moves you to the supply-only class from the date it is issued, and a rebate paid to anyone on the system counts even if you did not receive it. Ask ComEd in writing before switching rate or supplier, or applying to net meter added panels or a battery.
What ComEd bills you anyway
In a month when your production covers everything you use, the energy charge can reach zero. This does not. It is the floor under every bill, and it is the number that decides whether a system pays for itself.
- The charge
- $16.78 a month for a single-family home
- How it is set
- ComEd has no single figure: it splits residential into four delivery classes and the fixed monthly is two charges added together, a Customer Charge plus a Standard Metering Service Charge. For 2026 a single-family home without electric space heat pays $13.26 + $3.52 = $16.78; multi-family without electric heat $9.76 + $3.52 = $13.28; single-family with electric heat $15.09 + $3.52 = $18.61; multi-family with electric heat $10.57 + $3.52 = $14.09. Each is stated as "& ADJ", an adjustment applied on top, so the floor is a little above these. The sheet also carries 2025 and 2027 columns. Illinois is deregulated, so this is delivery only.

Applying to ComEd
What ComEd itself requires, as distinct from what the state rule requires. Read from its own published guidelines on the date shown.
- The change landed on 1 January 2025
- New solar participants from that date receive credit for exported electricity at their electricity supply rate rather than the full retail rate. Delivery charges are no longer offset by exports.
- Older systems keep full retail for life, on conditions
- Anyone net metering before 1 January 2025 keeps full retail crediting for the life of the system, as long as they keep meeting their class’s rules. At ComEd, a customer who "applies for net metering for an Eligible Facility on or after January 1, 2025", or whose system received a distributed generation rebate, is on the supply-only class instead.
- The distributed generation rebate can cost you the grandfathering
- ComEd’s distributed generation rebate is $300 per kW DC, about $2,100 on a 7 kW DC system. Under ComEd’s Rider POGNM a system that received it is on the supply-only class "even if such retail customer did not receive such DG Rebate", for example when an installer or leasing company claimed it. Get the trade in writing before anyone takes the check.
- Adding panels or a battery can change your class
- At ComEd the test is a new application for net metering, not the size of the change, and since June 2026 a battery interconnected with solar must sit on a time-of-use or hourly supply product. If you are on the old arrangement and thinking about expanding, ask your utility in writing which class the change puts you in before you sign.
- What supply-only actually does to a bill, in numbers
- The state program puts it plainly. Say your system sends 400 kWh to the grid in a month and you pull 500 kWh from it. Your net usage is 100 kWh. You pay supply and transmission charges on that 100 kWh, which is the netting working as you would expect. But you pay delivery charges on the full 500 kWh, because delivery is no longer part of the calculation at all. Delivery is a large share of an Illinois bill, so this is the whole of the change and it is why the headline number moved so far.
- Buy a house with older solar here and you can inherit the good rate
- ComEd’s Rider POGNM keeps a legacy class with "a successor retail customer at an eligible premises" for "the lifetime of the Distributed Electric Renewable Generating Facilities so long as such retail customer continues to meet the eligibility requirements of such classification". The exception is a system on which a distributed generation rebate was paid: a buyer is then on the supply-only class. Ask for the rebate history before you make an offer.
- The two utilities lose grandfathering in different ways
- It is not one statewide test. In ComEd territory the rider’s test is applying for net metering for an Eligible Facility on or after 1 January 2025. In Ameren territory the trigger is doubling the nameplate capacity of the project. A change that would be safe on one side of the state line between the two territories may not be safe on the other, so ask your own utility rather than reading a general Illinois article.
- MidAmerican counted a different date
- ComEd and Ameren decided eligibility on the date permission to operate was granted. MidAmerican decided it on the date a completed net metering application was submitted. For anyone still sorting out what rate they ended up on, that distinction is the reason two neighbors who signed in the same week can be on different tariffs.
- Ask which rate a quote assumes
- Supply rate and full retail rate differ by the whole delivery component. A savings estimate built on the wrong one is not slightly wrong, it is wrong by the largest line on the bill.

ComEd net metering questions
- Does ComEd offer one for one net metering?
- No. ComEd customers who began net metering on or after 1 January 2025 are credited for exports only against supply charges, never against delivery charges. On Rate BES, net exports earn kilowatt hour credits against the Electricity Supply Charge, Transmission Services Charge and Purchased Electricity Adjustment that can carry forward for the life of the system, or you can elect a monthly money credit at those three charges: 8.413 + 1.690 − 1.551 = 8.552 cents a kWh on a residential October 2026 bill, and the adjustment changes monthly. On time-of-use Rate BEST or hourly Rate BESH the credit is money at those time-varying supply prices. Customers already in the older classes before 1 January 2025, and later customers at the same premises, also get credit against per-kilowatt-hour delivery charges for the life of the system, as long as they keep meeting that class's rules (NM1 requires Rate BES) and no DG rebate was paid on the system.
- What does ComEd pay for power sent back to the grid?
- Exports offset supply charges only, never delivery, since 2025. Kilowatt hour credits under the post-2025 Rate BES class are not cashed out; they carry forward. If you receive a money credit, such as the monthly money credit option, the tariff effective 14 September 2026 lets you elect to have a net credit balance on a monthly bill paid to you on or before that bill's due date, or by the next due date if your request comes too late to process. Legacy pre-2025 customers keep a 12-month annual period, and unused credits expire at its end.
- Do I need a battery with ComEd?
- Yes, and we treat it as mandatory. Because ComEd does not credit exports one for one, the return has to come from using your own production rather than selling it, which after dark means storage and usually a larger array than a one for one utility would need. The other half is backup: panels alone shut off in an outage, so a battery is what keeps the house running in a storm. We do not refer panels-only systems in ComEd territory. This is our referral policy, not a legal or utility requirement.
- How do I find my ComEd bill?
- Sign in at comed.com. Open My Account, then Billing. Open the latest bill and save the PDF. Or screenshot the summary page. If you cannot get to it, a rough guess at your average monthly amount is enough to start.
- What is the catch with ComEd?
- Get ComEd to confirm in writing which net metering class you will be in, because banked kilowatt hour credits "will not transfer when there is a change in NM classification", including a switch to the monthly money credit, Rate BEST or a retail supplier. A battery interconnected on or after 1 June 2026 must stay on a time-of-use or hourly supply product such as Rate BEST or Rate BESH, so the Rate BES kilowatt hour credit is not available with it. If you began net metering on or after 1 January 2025 and buy supply from a retail electric supplier, ComEd pays no export credit, so get the supplier's terms in writing. If you have pre-2025 solar, taking ComEd's $300 per kW DC Resource 1 DG rebate moves you to the supply-only class from the date it is issued, and a rebate paid to anyone on the system counts even if you did not receive it. Ask ComEd in writing before switching rate or supplier, or applying to net meter added panels or a battery.
