Does ComEd still have net metering in 2026 — and how does it work now?
Yes. ComEd net metering is active in 2026 — what changed is the credit, not the program. Systems interconnected on or after January 1, 2025 earn supply-only credits, valued at ComEd's supply price of 10.399¢/kWh as of June 1, 2026. Systems interconnected by December 31, 2024 keep full-retail netting for the life of the system, which ComEd states as 30 years, unless they take the generation rebate.

What is supply-only net metering?
Supply-only netting is the rule for every ComEd system interconnected on or after January 1, 2025: electricity you export earns credits against the supply portion of your bill — the Price to Compare, 10.399¢/kWh effective June 1, 2026 — but not against delivery charges. Full retail net metering, which credited supply and delivery together, closed to new customers at the end of 2024.
Three buckets make up a ComEd bill: supply (the electricity itself), delivery (wires, poles, meters), and taxes and fees. Exported solar now touches only the first one. Solar you use directly is different — it avoids both supply and the usage-based part of delivery, because you simply buy fewer kilowatt-hours. That asymmetry is the single most important thing to understand about Illinois solar economics in 2026, and it is why self-consumption matters more than it used to.
Fixed charges behave differently again. ComEd's net metering FAQ states that the customer charge and standard metering charge "are not affected by net metering credits" — they are flat monthly amounts, not per-kilowatt-hour charges, so a kilowatt-hour credit has nothing to subtract from them. On ComEd's Hourly Pricing rate the credit works on a different basis entirely, which is covered below.

I installed solar before 2025 — do I keep full retail net metering?
Generally yes, and for a long time. ComEd's net metering FAQ states that customers who interconnected by December 31, 2024 keep full-retail netting — credits across supply, delivery, and taxes and fees — for the life of the solar energy system, which ComEd puts at 30 years. The rules changed for new interconnections; they did not reach back and strip existing ones.
The one way to lose it: taking the ComEd generation (smart-inverter/DG) rebate on a pre-2025 system converts it to supply-only netting permanently, and the choice is not reversible. Per CUB's fact sheet, taking only the storage rebate does not — the full rebate rules live in our Illinois battery incentives guide, and the solar-specific rebate math is broken down in our ComEd smart-inverter rebate guide. If you are on legacy netting and someone offers to "get you a $300-per-kW rebate," that trade is what you are being offered. Run the math before you sign.
| Legacy — interconnected before Jan 1, 2025 | Current — on/after Jan 1, 2025 | |
|---|---|---|
| Exports credited against | Supply + delivery + taxes and fees (full retail) | Supply only |
| Duration | Life of the system — ComEd states 30 years | Standard for all new systems |
| Do credits expire? | kWh credits reset annually in April or October, as elected on the Net Metering Election Form. Monetary credits do not expire for legacy customers on Hourly Pricing. | No — kWh or monetary credits do not expire |
| Smart-inverter rebate | Available — but the generation rebate converts you to supply-only, irreversibly | $300/kW solar; $300/kWh battery (battery rebate carries its own rate and program conditions) |
| Design implication | Oversizing penalized less | Self-consumption and right-sizing rewarded |
Buying a home with existing panels? The interconnection date decides which regime applies, so it is a document worth verifying before closing rather than after — and there is a form the new account holder has to file.
How do net metering credits show up on a ComEd bill?
As credits in the supply section, not as a payment. Per ComEd's FAQ, fixed-price customers who interconnected from 2025 on can choose kWh credits or monetary credits, and those credits do not expire. Customers buying at hourly prices receive a monetary credit based on the price of power during the hours they actually exported.
The practical read: in high-production months you bank credits, in winter you draw them down, and the balance carries forward rather than resetting. That is a meaningful improvement over the legacy annual reset — even though the legacy credit itself was worth more per kilowatt-hour. Your monthly bill will still show the customer charge, standard metering, and the delivery components exports do not touch.
One number to watch: 10.399¢/kWh is the residential Price to Compare effective June 1, 2026, and ComEd's next scheduled supply-price change lands October 1, 2026. Credit value moves with it. The October figure had not been published as of August 1, 2026, and we do not estimate it — we track it on our ComEd October 2026 rate reset page and update the day it posts.
The kWh-versus-monetary choice is recorded on ComEd's Net Metering Election Form, which is handled as part of your interconnection paperwork rather than published as a standalone download. ComEd does publish separate bill explainers for fixed-pricing customers under each option. Ask your installer which election was made on your behalf, and get the answer in writing.
Can net metering credits ever zero out a ComEd bill?
On the standard fixed-price rate, no. Credits there are measured in kilowatt-hours, they sit in the supply section, and ComEd states that the customer charge and standard metering charge "are not affected by net metering credits." On Hourly Pricing the mechanism is different: credits are a dollar value, calculated at the market price in the hours you exported, and ComEd's Hourly Pricing materials describe those credits being applied against the cost of your bill — with anything left over carried into the following billing cycle. The full hour-by-hour mechanics, including a documented $0-bill month and its counterexample, live on our dedicated ComEd Hourly Pricing + solar page.
The distinction is arithmetic, and it is worth understanding before anyone sells you on it. A kilowatt-hour credit can only reduce a charge that is itself billed per kilowatt-hour; it has nothing to subtract from a flat monthly fee. A monetary credit is a dollar balance, and ComEd describes applying it against what the bill costs. That is why both of ComEd's statements can be true at once, and it is the least-understood mechanic in Illinois residential solar.
Three conditions keep this honest:
- "Enough credits" is the whole condition. The dollar value of your exports has to exceed everything else on that bill. That is realistic in high-production months for a well-sized, owned system on the right rate. It is not a year-round outcome and it is never a guarantee.
- It is never a check. A credit balance beyond the bill rolls forward to future cycles. ComEd does not pay cash out — see the next section.
- Hourly Pricing floats both ways. Your supply price changes with the market every hour, so whether the rate suits your household's usage pattern is a separate decision from whether you go solar. ComEd's Hourly Pricing team takes exactly that question at 1-888-202-7787.
One thing ComEd has not made clear in writing. For a system interconnected on or after January 1, 2025 and billed on Hourly Pricing, ComEd's own materials pull in two directions: its net metering FAQ says post-2025 credits apply to the supply section, while the same answer describes credits reducing usage-based charges more generally, and its Hourly Pricing pages describe credits applying against the cost of the bill. The gap between those readings is worth roughly six cents per kilowatt-hour.
We are not going to resolve an ambiguity ComEd created. If this matters to your decision — and if a battery or a large array is involved, it does — ask ComEd for the answer in writing before you sign anything, and keep the reply. We would rather tell you a question is open than hand you a number we cannot source.
None of this is a savings promise. It is ComEd's published mechanics, and whether your roof, your usage, and the hourly rate line up is exactly what an honest review checks.
Not sure which of these rules apply to you?
Most people are one question away from knowing — your interconnection date decides almost everything on this page.

Does ComEd pay cash for excess solar power?
No. The value arrives as credits against your ComEd charges — never as a check and never as income. Post-2024 fixed-price customers may elect a monetary bill credit rather than a kWh credit, but it still offsets what you owe ComEd. Nobody is being paid by the utility for their roof.
This is where net metering gets confused with Illinois Shines, a genuinely separate program that pays for your system's renewable energy credits — and pays them to your Approved Vendor, not to you. Two different programs, two different mechanisms, both applying to the same system: how Illinois Shines actually works and pays. Confirming your installer is genuinely on that Approved Vendor list is worth doing before you sign — how to verify an Illinois Shines vendor. Ownership matters there too, since customer-owned systems earn a $20/REC adder that changes the math against leasing: lease vs PPA vs buying, compared.
If a salesperson tells you ComEd will "buy back" your power or send an annual true-up check, that is not how the ComEd tariff works, and it is worth treating as a signal about the rest of the pitch — the same goes for dealer fees quietly folded into a loan rather than disclosed upfront. Our quote-vetting checklist and our breakdown of Illinois solar dealer fees cover the other claims worth testing.
Which ComEd net metering rules apply to me?
Four questions decide almost everything on this page. Your answers stay in your browser — nothing is submitted, and the result tells you plainly when the answer is "this doesn't apply to you."
Answer the questions above and your result appears here.
How does supply-only netting change what size system I need?
It rewards matching your usage instead of maximizing exports. Exported kilowatt-hours now earn supply-level credits, while self-consumed kilowatt-hours avoid the full retail cost — so the system that pencils best is the one sized to what you actually use, not the biggest one that fits on the roof.
There is no longer a 110% cap. ComEd removed that limit on March 1, 2022, and it appears nowhere in ComEd's current net metering materials. What ComEd publishes today is guidance rather than a ceiling: your system "should be sized to meet some or all of your current or future energy needs." ComEd's materials also contemplate systems that out-produce annual usage, and describe crediting the surplus rather than refusing it. Anyone still quoting a 110% rule at you is working from four-year-old information.
- Start from your own 12 months of usage, available in your ComEd account — not a state average.
- Two ceilings do exist, and neither is usage-based: Illinois limits an eligible net metering facility to 2,000 kW, and the fast-track Level 1 interconnection path covers systems up to 25 kW of export capacity. Residential rooftop sits far below both.
- West-facing arrays age well here — late-afternoon production lines up with evening consumption, which is worth more than exporting it.
- Batteries earn their keep differently now — storing midday solar for evening use beats exporting it, though the rebate that funds them carries commitments of its own: is a home battery worth it in Illinois?
- Watch for offers that aren't really a state program — some ComEd-territory pitches now bundle a battery with an electricity-supply contract, and those multi-year agreements aren't compatible with rooftop solar at all: what those contracts actually say.
- Demand a production model built on supply-only rules and your real usage. A generic savings curve is not one. The method is in our guide to how many panels an Illinois home needs.
How do I apply for ComEd net metering?
You generally do not apply separately. ComEd's materials state that the interconnection application covers net metering enrollment, and participation begins once that application is approved and the Certificate of Completion confirming permission to operate is signed. Your installer normally files it. Your job is confirming it happened — and knowing the deadlines ComEd is working under.
A typical Illinois home system runs through Level 1 expedited review, the fastest of four paths under the state interconnection rule, 83 Ill. Adm. Code Part 466. To qualify, the system must have export capacity of 25 kW or less and nameplate capacity of 50 kW or less — and if export is not limited, nameplate cannot exceed 25 kW — plus be inverter-based and use lab-certified equipment. Essentially every residential rooftop array in ComEd territory clears this comfortably.
What it costs to apply
The Level 1 application fee is $50, published both in the state rule's application form and on ComEd's own smaller-generators page. Part 466 separately sets a standardized Level 1 interconnection cost of $200, and provides that where ComEd's costs exceed that, it recovers the difference through base delivery rates rather than billing you. An optional pre-application report — rarely needed for rooftop solar — costs $300 and must be returned within 20 business days.
The steps, in order
- Level 1 interconnection application filed with ComEd, with the $50 fee. Stating intent to generate covers net metering enrollment; there is no second application.
- ComEd confirms the application is complete, then evaluates it against the Level 1 technical screens.
- Conditional approval — ComEd countersigns, conditional on the electrical inspection, the returned Certificate of Completion, and a successful witness test.
- Installation and local electrical inspection by your municipality or county — a separate process from ComEd's interconnection review, and worth not conflating: Chicago and Aurora each run their own permitting rules, covered in our Chicago solar permits and Aurora solar permits guides. Operational testing is limited; the system may not otherwise run before permission to operate.
- Certificate of Completion submitted to ComEd with verification of the inspection.
- Meter verified or exchanged so it can measure flow in both directions.
- Witness test, then ComEd countersigns and returns the Certificate. That signature is permission to operate.
About the disconnect switch
This one is widely misreported in both directions. Part 466 does not flatly require every homeowner to install an external disconnect switch — it says the utility may require the system to be capable of being isolated. Where ComEd does require it, the isolation device must be installed, owned and maintained by you, and for a home connected to a secondary line through a standard self-contained meter, the rule states that ComEd simply removing the meter may satisfy the requirement. Separately, and unconditionally, ComEd's interconnection agreement gives it access to the disconnect and metering equipment at all times, with five business days' notice except in emergencies. Ask your installer what ComEd is requiring at your specific address, in writing, before the equipment order is placed.
You can track application status yourself through ComEd's MyGeneration portal rather than relying on status updates from a salesperson. Two things worth knowing about the meter: it records flow in both directions, and it does not measure your panels' production. Use your installer's monitoring app for that.
How long does ComEd have to approve interconnection and grant PTO?
Longer than most homeowners realize they can ask about — and shorter than many installers imply. Part 466 puts ComEd on the clock at four separate points in a Level 1 residential interconnection, and the last one is the important one: once your system passes its witness test, ComEd has ten business days to sign and return the Certificate of Completion, and the rule states that the authorization shall not be conditioned or delayed.
| Step | Who acts | Deadline | Where it's written |
|---|---|---|---|
| Application filed with the $50 Level 1 fee | You / your installer | — | 466.90(b)(1) |
| "Is it complete?" notice | ComEd | 7 business days from receipt | 466.90(b)(2) |
| Level 1 technical screens run | ComEd | 15 business days after the completeness notice | 466.90(b)(3) |
| Sign the interconnection agreement | You | 30 business days, or it's deemed withdrawn — an initial 15-business-day extension cannot be refused | 466.90(b)(5)(D) |
| Install + local electrical inspection | You, installer, local inspector | Not set by Part 466 | — |
| Witness test | ComEd | 10 business days of the commissioning date — if ComEd misses it without good cause, the witness test is deemed waived | Part 466, Appendix A |
| Certificate returned = permission to operate | ComEd | 10 business days after the system passes, and not to be conditioned or delayed | Part 466, Appendix D, Art. 2.1.3 |
Where the clock stops, honestly. Part 466 sets no deadline for ComEd to finish building any interconnection facilities or distribution upgrades a project turns out to need. Most residential rooftop systems need none — but if yours does, that stretch of the timeline is genuinely open-ended, and no page claiming a guaranteed total timeline can back it. That is also why real-world installer estimates of a few weeks between final inspection and PTO are an observation about how it usually goes, not a rule anyone can hold ComEd to.
What if my interconnection stalls?
You have a written escalation path, and it is not "call your installer again." Part 466 contains its own dispute process, and above it sits the Illinois Commerce Commission, which regulates ComEd.
- Put it in writing to ComEd, naming the deadline you believe has passed. Vague follow-ups get vague answers; a dated reference to a specific rule does not.
- Request the Part 466 informal process. After written notice, an informal meeting is to be held within 10 business days, with people who can actually decide something in the room. The informal period runs 30 days.
- File an informal complaint with the ICC — Consumer Services, 1-800-524-0795, or through the ICC's public utility complaint page. This is free, it is the step most homeowners never learn exists, and utilities respond to it.
- Formal complaint, heard by an Administrative Law Judge, if the informal route fails. Note that the rule puts a clock on you here too — after the informal and arbitration steps conclude, the window to file formally is short.
Keep every document: the application, the conditional approval, the inspection sign-off, the Certificate of Completion, and the date of your witness test. The deadlines in the table above are only useful if you can show when the clock started.
What are ComEd net metering credits actually worth?
Multiply the kilowatt-hours you export by the supply price, and that is the honest answer for a post-2024 system. At 10.399¢/kWh, exports are worth a real but modest amount — which is precisely why sizing to self-consumption beats sizing to export.
Arithmetic only, at ComEd's residential Price to Compare of 10.399¢/kWh effective June 1, 2026 — not a projection, not a savings estimate, and not a quote. It values exports alone; electricity you use as you generate it is worth more, because it avoids delivery charges as well as supply. It also does not touch the fixed customer and metering charges, which run roughly $19 a month on the standard single-family class and are broken down in our guide to your electric bill after solar. Curious what a system costs before any of these credits start accruing? See our Illinois solar cost breakdown. The supply price changes October 1, 2026.
What happens to net metering when I sell my house?
The system and its status attach to the home, not to you — but the new owner does have one thing to file. ComEd states that someone starting service at a premise that already has solar does not submit a new interconnection or net metering application. They do need to complete ComEd's Ownership/Name Change Form and send it to [email protected] within 60 days of starting service.
Note where that clock starts: starting service, not closing. A buyer who takes a few weeks to move in and open the ComEd account is working from the account date, and the window is easy to lose track of during a move. The form is linked from ComEd's net metering and interconnection FAQ page.
Keep the interconnection approval and the Certificate of Completion permanently. On a pre-2025 system that paperwork is what proves a buyer is inheriting legacy full-retail netting — a real, transferable asset worth naming in the listing. The broader sale checklist lives in our guide to selling a house with solar in Illinois.
How is ComEd net metering different from Ameren Illinois'?
Same idea, different math, and the differences are worth knowing if you are comparing quotes across the territory line. ComEd systems interconnected from 2025 on earn supply-only credits; Ameren Illinois credits exports against supply and transmission charges. The legacy tests differ too — ComEd keys on the interconnection date, while Ameren required a Construction Complete form filed in PowerClerk by 5 p.m. CST on December 31, 2024. Part of why Ameren's numbers move differently: why Ameren bills have been climbing too.
| Difference | ComEd | Ameren Illinois |
|---|---|---|
| Exports credited against | Supply only | Supply + transmission |
| Legacy full-retail test | Interconnected by Dec 31, 2024 | Construction Complete form in PowerClerk by 5 p.m. CST, Dec 31, 2024 |
| Credit election | kWh or monetary — neither expires for post-2024 systems | One-time kWh Yes/No election — irreversible |
| How legacy is lost | Taking the generation (smart-inverter) rebate | Generation rebate — or a 100%+ system-size increase |
That is the comparison, not the full picture. Ameren's own rules — its crediting election, its application path, and its rebate conditions — are covered in full on their own page: Ameren Illinois net metering, explained.
Did the 2026 CRGA law change ComEd net metering?
No. The Clean and Reliable Grid Affordability Act — Public Act 104-0458, effective June 1, 2026 — is the biggest Illinois energy law in years, and it left solar export crediting alone. Supply-only netting for post-2024 systems and legacy full-retail status for pre-2025 systems both survive it unchanged.
What CRGA did touch sits next door: energy storage rebates (see the ComEd battery storage rebate for the dollars, and its conditions) and the framework for utility virtual power plant programs (ComEd's and Ameren's), the state's nuclear provisions, and a grid-operator study due to the Illinois Commerce Commission at the end of 2026. If a battery is part of your conversation, those changes matter a great deal. If you are looking only at panels, CRGA does not change the answer on this page.
We flag this because the law's passage produced a wave of coverage suggesting Illinois solar rules had been rewritten. For net metering specifically, they were not. For the full picture of every incentive that DOES apply in 2026 — Illinois Shines, the rebate, and this page's net metering rules stacked together — see our Illinois solar incentives guide.
ComEd net metering glossary
- Net metering
- The arrangement under which electricity you export to the grid earns credits on your utility bill. In Illinois it is governed by 220 ILCS 5/16-107.5 and the utility's own tariff.
- Supply-only netting
- The crediting rule for ComEd systems interconnected on or after January 1, 2025: exports credit the supply section of the bill, not delivery.
- Legacy status
- Full-retail net metering retained by systems interconnected on or before December 31, 2024, which ComEd states lasts for the life of the system — 30 years.
- Price to Compare
- ComEd's published residential supply price, the rate that sets what an exported kilowatt-hour is worth. 10.399¢/kWh effective June 1, 2026.
- Interconnection
- The regulated process of connecting a generating system to the utility's distribution grid. Governed in Illinois by 83 Ill. Adm. Code Part 466.
- Level 1 review
- The fastest of four interconnection review paths, for inverter-based, lab-certified systems with export capacity of 25 kW or less. Nearly all residential rooftop solar.
- Certificate of Completion
- The document submitted after installation and inspection. ComEd's countersignature on it is permission to operate.
- Permission to operate (PTO)
- Utility authorization to actually run the system in parallel with the grid. Until it is granted, the system may not operate.
- Witness test
- ComEd's inspection of the finished installation. It must occur within 10 business days of commissioning, or it is deemed waived absent good cause.
- Isolation device
- Equipment allowing the utility to disconnect your system from the grid. Where required, it is installed, owned and maintained by the system owner.
- Hourly Pricing (Rate BESH)
- ComEd's optional market-following supply rate. Net metering credits on it are calculated as a dollar value at the hourly market price.
ComEd net metering FAQ
Does ComEd still offer net metering in 2026?
Yes. Systems interconnected on or after January 1, 2025 receive supply-only net metering — exported energy credits the supply section of the bill. The program is active; what changed is the credit structure, not its existence.
What is supply-only net metering?
Exports earn credits against supply charges — the electricity itself, currently 10.399¢/kWh at ComEd — rather than against delivery charges. Per the Illinois Shines FAQ and ComEd's own materials, it is the standard for all new residential interconnections since January 1, 2025.
I installed solar before 2025 — do I keep full retail net metering?
Generally yes. ComEd's net metering FAQ states customers who interconnected by December 31, 2024 keep full-retail netting — credits across supply, delivery, and taxes and fees — for the life of the solar energy system, which ComEd puts at 30 years.
Can I lose my legacy net metering by accident?
Yes — one way. Taking ComEd's generation (smart-inverter) rebate on a pre-2025 system permanently converts it to supply-only netting, and it is not reversible. Per CUB's fact sheet, taking only the storage rebate does not trigger the conversion.
Do ComEd net metering credits expire?
Not for systems interconnected on or after January 1, 2025 — ComEd states those credits, kWh or monetary, do not expire. Legacy fixed-price customers' kWh credits do reset annually, in April or October, as elected on their Net Metering Election Form. Monetary credits do not expire for legacy customers on Hourly Pricing.
Can solar ever bring a ComEd bill to zero?
On the standard fixed-price rate, no — credits there are measured in kilowatt-hours, and ComEd states the customer charge and standard metering charge are not affected by net metering credits. On Hourly Pricing the credit is a dollar value, and ComEd's Hourly Pricing materials describe credits being applied against the cost of the bill with any excess carried to the following cycle. It requires a large enough credit balance, it is not a year-round outcome, and it is never paid out as cash.
Does ComEd pay cash for excess solar power?
No — the value arrives as credits on your bill, not checks. Post-2024 fixed-price customers may elect a monetary bill credit, but it offsets your ComEd charges rather than being paid out as income. There is no annual true-up check.
Do I apply for ComEd net metering separately?
Usually not. Per ComEd's materials, the interconnection application covers net metering, and participation begins once the application is approved and the Certificate of Completion confirming permission to operate is signed.
How long does ComEd have to grant permission to operate?
Once your system passes its witness test, ComEd has 10 business days to sign and return the Certificate of Completion, and Part 466 states the authorization shall not be conditioned or delayed. Earlier in the process ComEd has 7 business days to confirm your application is complete and 15 business days after that to run the Level 1 screens. No deadline applies to building any grid upgrades a project may need.
What does a ComEd interconnection application cost?
The Level 1 application fee is $50, published in the state rule's application form and on ComEd's smaller-generators page. An optional pre-application report costs $300. Part 466 also sets a standardized Level 1 interconnection cost of $200, with any excess recovered through ComEd's base delivery rates rather than billed to you.
Do I need an external disconnect switch for solar in Illinois?
Not automatically. Part 466 allows the utility to require that a system be capable of being isolated; where ComEd requires it, the isolation device is installed, owned and maintained by the system owner. For a home on a secondary line with a standard self-contained meter, the rule states ComEd's removal of the meter may satisfy the requirement. Confirm what ComEd requires at your address in writing before equipment is ordered.
How large a solar system can I install under ComEd net metering?
There is no percentage cap. ComEd removed the old 110% of historical usage limit on March 1, 2022 and now publishes guidance that a system should be sized to meet some or all of current or future energy needs, while contemplating systems that produce more than annual usage. Illinois limits an eligible net metering facility to 2,000 kW, and Level 1 fast-track interconnection covers up to 25 kW of export capacity.
What happens to net metering if I sell my house?
The system and its status attach to the home. ComEd states a new account holder at a premise with existing solar does not file a new interconnection or net metering application, but must complete ComEd's Ownership/Name Change Form and send it to [email protected] within 60 days of starting service — the clock runs from starting service, not from closing.
Did the CRGA law change Illinois net metering in 2026?
No. The Clean and Reliable Grid Affordability Act, Public Act 104-0458, took effect June 1, 2026 and did not change solar export crediting. Supply-only netting for post-2024 systems and legacy full-retail status for pre-2025 systems both continue unchanged. CRGA addressed storage rebates, the virtual power plant framework, nuclear provisions, and a grid-operator study.
Is ComEd net metering the same as Ameren's?
No. Ameren Illinois credits exports against supply and transmission charges, while ComEd systems interconnected from 2025 on earn supply-only credits. The legacy cutoffs differ too: ComEd keys on interconnection by December 31, 2024, while Ameren required a Construction Complete form in PowerClerk by 5 p.m. CST that same day — the full rules are in our Ameren net metering guide.
When does ComEd's 10.399¢ supply price change?
That figure is ComEd's residential Price to Compare effective June 1, 2026, and the next scheduled supply-price change is October 1, 2026. Net metering credits are valued at whatever the supply price is at the time, so their value moves with it. The October figure was not published as of August 1, 2026; current numbers are posted on Plug In Illinois.

August 1, 2026 — v3: added the interconnection application and permission-to-operate process with Part 466 deadlines, an interconnection escalation path, a rules checker and a credit-value estimator, two original diagrams, a glossary and a CRGA section; removed the 110% sizing cap, which ComEd eliminated on March 1, 2022; corrected the home-sale section to include the 60-day Ownership/Name Change Form; updated the ComEd net metering FAQ citation to the 2026 edition; FAQ expanded from 11 to 16 questions. August 7, 2026 — v3.1: internal-linking pass, no fact changes (all figures re-verified current, incl. the still-unpublished Oct 1 rate reset). Added 13 links to related guides across #legacy, #payout, #design, #apply, #estimator, #vs-ameren, #crga and the related-answers grid, incl. the previously-missing pointer to the Illinois solar incentives pillar; kept this page's FAQ set as-is per the site's internal cannibalization review (comed-solar carries the trim on its side of the 6 shared questions). August 7, 2026 — v3.2: reader-engagement pass, no fact changes. Added a scroll progress indicator, a mobile sticky eligibility bar, three pull-quote callouts ($50 application fee, the 2022 sizing-cap removal, the 30-year legacy figure), two "next section" pointers, an early link to the rules checker for skim-readers, and a reading-time estimate.
