Illinois SRECs are solar renewable energy credits that the state buys from system owners through a program called Illinois Shines. For the 2025–26 program year, a typical residential system earns roughly $66 to $75 per credit, and the full 15-year value is paid as a single lump sum shortly after your panels are installed and verified. The Illinois Power Agency runs the program, sets the prices, and requires every project to go through a state-registered Approved Vendor.1Illinois Power Agency. Illinois Shines Factsheet
What an SREC Actually Is
When your solar panels generate electricity, they produce two things: the power itself and a separate environmental attribute called a Renewable Energy Credit. Illinois Shines buys those credits from you under a long-term contract, and that purchase is what people mean when they talk about the SREC payment. The credits count toward utilities’ obligations under the state’s Renewable Portfolio Standard, and at least half of Illinois’s solar REC procurement target flows through Illinois Shines.2DSIRE. Adjustable Block Program (Illinois Shines)
The price you get is locked in when your Part I application is approved, so the rate does not drift up or down after you’re in.
Current REC Prices by System Size
Prices vary by system capacity and by which pricing group your application falls into. Smaller systems earn more per credit because their per-watt installation costs are higher. For the 2025–26 program year, distributed generation REC prices are:3Illinois Power Agency. IL Shines REC Prices 2025-2026 Program Year
- 0–10 kW (typical residential): $66.34 to $75.48
- 10–25 kW (larger residential or small commercial): $57.18 to $69.78
- 25–100 kW: $59.53 to $69.65
- 100–200 kW: $55.63 to $65.09
- 200–500 kW: $45.64 to $53.40
- 500–2,000 kW: $42.37 to $49.57
- 2,000–5,000 kW: $31.96 to $37.39
Public school projects get their own higher pricing tier, running from $42.15 to $93.17 depending on system size.3Illinois Power Agency. IL Shines REC Prices 2025-2026 Program Year
Your total payout is the price per REC multiplied by the credits your system is estimated to produce over the contract term. Illinois Shines uses a declining-block structure: when a block fills to capacity, the next block opens at a lower price. Applying earlier in a program year usually means a better rate.
Who Qualifies
The program divides projects into Small Distributed Generation, which covers systems up to 25 kW and includes most home rooftop arrays, and Large Distributed Generation for systems above 25 kW up to 5 MW.4Illinois Shines. Small Distributed Generation5Illinois Shines. Large Distributed Generation
To qualify, your project must:6Illinois Shines. Adjustable Block Program Program Guidebook
- Be located in Illinois and connected to an Illinois electric utility, or to a municipal utility or rural cooperative that has opted in.
- Use new panels, inverters, and racking that have never previously generated electricity.
- Have received permission to operate from the utility on or after June 1, 2017. Systems energized before that date are not eligible.
- Have documented site control, meaning the Approved Vendor can show a deed, lease, letter of intent, or similar proof.
- Be interconnected with the grid so production can be measured.
Homeowners, commercial property owners, tenants with site control, nonprofits, and public schools can all participate. If you can’t put panels on your own roof, community solar subscriptions are a separate track under Illinois Shines with their own pricing.
How and When You Get Paid
For a residential system up to 25 kW, Illinois Shines pays 100 percent of the REC contract value as a lump sum at energization.4Illinois Shines. Small Distributed Generation You receive the full 15-year value shortly after your Part II application clears, not spread out over the contract.
Larger projects are paid differently. Systems above 25 kW up to 5 MW get 15 percent at energization, with the rest paid out ratably over six years.7Illinois Shines. REC Contracting and Re-Batching Traditional community solar projects run on a pay-as-deliver basis over 20 years, with biannual adjustments tied to subscription reports.8Illinois Shines. Part I and II Application Timeline
The utility pays your Approved Vendor directly. The vendor then passes your share along, either as a check or as a reduction in the cost of the installation, depending on how your contract with them is structured.9Illinois Shines. Sample DG Power Purchase Agreement Disclosure Form That arrangement is one of the most important things to nail down before signing anything.
Projects approved by the Illinois Commerce Commission after June 1, 2026, use updated 2026 REC delivery contracts with both 15-year and 20-year options depending on the project category.10Illinois Shines. 2026 Long-Term Renewable Resources Procurement Plan and Illinois Power Agency Publishes Final 2026 Illinois Shines REC Delivery Contracts
Applying Through an Approved Vendor
You cannot apply to Illinois Shines yourself. Every application goes through an Approved Vendor registered with the program, and the state maintains a public directory where you can confirm a company is in good standing before you hire them.11Illinois Shines. Find An AV, Designee, or Subcontractor
The vendor submits a Part I application while the project is still being planned. Part I details the planned size, equipment, and estimated production, and it reserves your spot at the current block’s price.12Illinois Shines. Illinois Shines Portal Help Guides – Part I Applications Once the system is installed and the utility grants permission to operate, the vendor submits Part II with final documentation and photos verifying that what was built matches what was proposed.13Illinois Shines. Illinois Shines Portal Help Guides – Part II Applications Payment does not release until Part II clears.
Waitlists
Each program year has a fixed amount of incentive capacity. When capacity runs out for a specific pricing group and project category, new applications go onto a waitlist and get priority when capacity reopens, most commonly at the start of the next program year.14Illinois Shines. Consumer FAQs
Being waitlisted delays your Illinois Shines payment but does not affect net metering credits or any federal tax credit you’re entitled to. Ask your vendor about current block availability before signing. If a block is close to full, moving quickly can be the difference between locking in today’s price and waiting for a lower one.
What to Check Before You Sign
Before you sign an installation contract or subscription agreement, your Approved Vendor is required to give you a standardized Disclosure Form for your signature.15Illinois Shines. Vendor Disclosure Form Resources The form lists the total system cost, expected energy production, the system’s nameplate capacity in kilowatts, first-year production in kilowatt-hours, and the anticipated value of the REC incentive. It’s the document that lets you check the vendor’s numbers against what the state has actually approved.
If a vendor pushes you to sign the installation contract before providing the Disclosure Form, that runs against program rules. The Illinois Power Agency can order corrective actions, additional training, suspension of a vendor’s ability to register new projects, or full revocation of Approved Vendor status for consumer protection violations.16Illinois Shines. Consumer Protection Handbook Severe cases can be referred to the Illinois Attorney General’s Office or the Illinois Commerce Commission. The IPA publishes information about enforcement actions, so a vendor’s history is at least partly visible before you hire them.
The 15-Year Obligation Behind the Lump Sum
The upfront payment covers 15 years of RECs. Even though the money arrives shortly after installation, your system is expected to keep producing those credits for the full contract term, and the credits go to the program to help meet Illinois’s renewable energy targets. The specific terms covering underperformance, damage, or any clawback provisions live in the REC delivery contract itself. Ask your vendor to walk through those provisions before you sign rather than discovering them later.
Other Benefits That Stack on Top
The SREC payment is separate from net metering, which credits you on your utility bill for excess electricity your system exports. Illinois currently uses supply-only net metering, so you get credit against the supply portion of your bill but continue paying delivery charges on any electricity you pull from the grid.17Illinois Solar for All. Net Metering Changes in Illinois – Frequently Asked Questions for Participants Net metering credits and any applicable federal residential clean energy credit are on top of your Illinois Shines payment, not netted against it. Federal credit availability has changed recently, so confirm the current year’s rules with the IRS or a tax professional before counting on a specific amount.
