What is Illinois Shines, and how does it actually pay?
Illinois Shines is the state's solar incentive — officially the Adjustable Block Program, run by the Illinois Power Agency. For 2026–27 it pays $80.77 per renewable energy credit in ComEd territory and $70.37 in Ameren territory, plus $20 more per REC if you own the system. Payments go to your Approved Vendor — 50% at energization, the rest over six years — and typically reach you as a lower contract price.

What is Illinois Shines?
Illinois Shines is the everyday name for the Adjustable Block Program — the state solar incentive, administered by the Illinois Power Agency, under which utilities buy renewable energy credits (RECs) from qualifying systems at published prices. Created by the Future Energy Jobs Act in 2016 and expanded by the Climate & Equitable Jobs Act in 2021, it's the largest Illinois-specific solar incentive.
One REC represents one megawatt-hour (1,000 kWh) of production. Residential systems are contracted over a 15-year delivery term based on the system's IPA-approved production model — not metered month to month. The 2026–27 program year opened June 1, 2026.
How much does Illinois Shines pay in 2026?
For program year 2026–27, published REC prices are $80.77 in ComEd territory (Group B) and $70.37 in Ameren Illinois territory (Group A) for systems up to 10 kW — plus a $20-per-REC adder when the customer owns the system. Larger residential tiers price lower per REC, and prices are set by block.
| Parameter (PY 2026–27) | Value |
|---|---|
| Group B REC price — ComEd territory, systems ≤10 kW | $80.77/REC |
| Group A REC price — Ameren Illinois territory, ≤10 kW | $70.37/REC |
| Customer-owned adder (cash or loan ownership) | +$20/REC |
| Larger residential tiers (>10–25 kW, Small DG) | Priced lower per REC — see the IPA price sheet |
| REC delivery term | 15 years |
| What 1 REC represents | 1 megawatt-hour (1,000 kWh) of production |
As a scale illustration, a customer-owned 7 kW system in ComEd territory can represent roughly $12,000–$13,000 of gross REC value across the 15-year term. The worked math — and the caveats that come with it — lives on our Illinois Solar Facts hub; the full incentive stack is on our Illinois Solar Incentives guide.
Who actually receives the money — and when?
Not you, directly — and never quarterly. Under the Consumer Rate Guarantee Act (Public Act 104-0458, effective June 1, 2026), REC payments go to the project's Approved Vendor: 50% at energization, with the remainder paid ratably over the subsequent six years. Your benefit typically arrives as a lower contract price or better terms — not a check in the mail.
That makes one question non-negotiable when comparing offers: how, exactly, is the REC value reflected in my price — stated in dollars, in writing? Your Illinois Shines Disclosure Form should match what the salesperson said; if the pitch and the form differ, believe the form. Any pitch describing quarterly homeowner REC checks is describing the program wrong — twice.
Who are Approved Vendors and Designees — and what's the Disclosure Form?
An Approved Vendor is the IPA-registered entity that submits your project into Illinois Shines and holds the REC contract. A Designee — often the installer or sales company you actually deal with — operates under an Approved Vendor's registration. Before you sign anything, they must provide the IPA-required Disclosure Form stating system size, projected production, price, and terms.
Every legitimate Illinois Shines pitch can name its Approved Vendor — verify it on the program's official Approved Vendors & Designees list. Refusal to name the vendor or produce the Disclosure Form ends the conversation. Problems with a seller go to the Illinois Shines Consumer Complaint Center.
What is Illinois Shines not — and what stacks with it?
It's one of three separate value streams — and it's none of the others. Illinois Shines is not net metering (how exports credit your bill — supply-only for systems interconnected on or after January 1, 2025), not the $300/kW smart-inverter rebate (a separate one-time utility payment), and not the federal tax credit, which expired December 31, 2025.
- Net metering governs bill credits for exported energy — covered in depth in our ComEd Solar Guide.
- The smart-inverter rebate ($300/kW solar; $300/kWh battery with a qualifying rate) is a separate utility payment — see the facts hub.
- The federal §25D credit ended December 31, 2025 — what expired and what didn't: Did the solar tax credit end?
- Illinois Solar for All is the separate income-eligible pathway with its own rules — overview here.
All three state-level pieces — Shines RECs, supply-only netting, and the rebate — stack on the same system.
Is Illinois Shines still available right now?
Yes — the 2026–27 program year opened June 1, 2026 with fresh capacity. But capacity is allocated in finite blocks that fill through the year, so we never publish a live availability number here. Check the program's official Block Capacity Dashboard yourself — and treat any salesperson's countdown as unverified until you've seen it there.
How do you actually get Illinois Shines?
You never file with the state — the Approved Vendor does. Your side: receive the Disclosure Form before signing, let the vendor submit the project for pre-installation review, install under local permits and utility interconnection, pass post-installation verification, then energize — which triggers the first 50% payment to the vendor, with the remainder following over six years.
- Disclosure Form first. Provided before you sign anything — size, projected production, price, terms.
- Project submission. The Approved Vendor submits your project for pre-installation review (Part I).
- Installation under local permits and ComEd/Ameren interconnection approval.
- Post-installation verification (Part II) confirms the system as built.
- Energization. The system turns on with permission to operate — triggering the first 50% REC payment to the vendor.
- Remaining payments flow to the vendor ratably over the subsequent six years.
Your leverage points are the Disclosure Form, the contract, and knowing which Approved Vendor holds the project.
Illinois Shines FAQ
Is Illinois Shines the same as the federal solar tax credit?
No. Illinois Shines is a state program and remains active for 2026–27. The federal residential credit (§25D) expired December 31, 2025 and can't be claimed on 2026 cash or loan purchases — the two are unrelated programs with unrelated rules.
Do homeowners get an Illinois Shines check every quarter?
No — twice over. Payments go to the Approved Vendor, not the homeowner, as 50% at energization plus the remainder ratably over the subsequent six years under PA 104-0458. Your benefit typically arrives as a lower contract price.
How much is the $20 customer-owned adder actually worth?
It stacks on the base price when you own the system with cash or a loan: $100.77 per REC in ComEd territory and $90.37 in Ameren territory on the ≤10 kW tier — a concrete, sourced reason ownership out-earns third-party deals on REC value.
Does a lease or PPA still get Illinois Shines value?
Yes — at the base REC price, without the $20 adder, paid to the system's owner. Whether any of that value reaches you depends entirely on the offer's pricing, so ask for the pass-through stated in dollars, in writing.
How many RECs will my system produce?
One REC per megawatt-hour. As an illustration, a 7 kW system producing around 1,200 kWh per kW annually generates roughly 8.4 MWh a year — about 126 RECs across the 15-year term. Your actual count comes from the program's IPA-approved production model for your specific roof.
What is the Illinois Shines Disclosure Form?
The standardized, IPA-required document every Approved Vendor or Designee must provide before contract signing — system size, projected production, price, and terms in one place. No form, no signature. If the form and the pitch differ, believe the form.
Can Illinois Shines run out of money?
Capacity is finite and allocated in blocks per program year — blocks can fill, and new projects may wait for reopened capacity. Check current status on the official Block Capacity Dashboard rather than relying on any sales claim about scarcity.
Does Illinois Shines stack with net metering and the smart-inverter rebate?
Yes. They're three separate programs that apply to the same system: Shines pays for RECs, supply-only net metering credits your exports, and the $300/kW smart-inverter rebate is a one-time utility payment. Each has its own rules.
