Illinois Shines explained: 2026-27 REC prices, timing, and rules.

The first time many homeowners hear about Illinois Shines, it comes out of a salesperson's mouth as a number. A claim such as "you'll get money back from the state" skips important facts: the program uses utility REC contracts with Approved Vendors, and the customer's value and payment path depend on the Disclosure Form and agreement.

Illinois Shines can be an important part of a qualifying Illinois project, and it is also easy to describe incorrectly, so this is the plain version.

What Illinois Shines actually is

Illinois Shines is the public name for the state-administered Adjustable Block Program. The Illinois Power Agency oversees the program, and Approved Vendors enter REC contracts with contracting utilities for qualifying projects.

The mechanism is different from a tax credit and different from a utility rebate. Solar production can create Renewable Energy Credits, or RECs. One REC represents the environmental attributes of one megawatt-hour, or 1,000 kilowatt-hours, of qualifying generation. When those RECs are sold, the purchaser owns the associated renewable-energy attributes.

For a Small DG project, the program contract covers fifteen years of REC deliveries. The contracting utility pays the Approved Vendor under that contract. The customer's Disclosure Form and agreement must explain whether the REC value appears as a price reduction, separate payment, or another contractual benefit.

Illinois Shines REC prices for 2026-27

The price per REC is set each program year by the Illinois Power Agency and varies by project category, system size, and utility group. Residential Small Distributed Generation projects from zero to 10 kW AC and projects above 10 through 25 kW AC have separate price categories. ComEd territory is generally Group B, while Ameren Illinois territory is generally Group A.

For the 2026-27 program year that started June 1, 2026, qualifying 0-10 kW AC projects have a base price of $70.37 per REC in Group A, which includes Ameren territory, and $80.77 per REC in Group B, which includes ComEd territory. A $20-per-REC customer-owned Small DG adder may apply when all Program requirements are met.

With that eligible adder, the applicable prices would be $90.37 in Group A and $100.77 in Group B. Those are program-contract prices, not promises of what a homeowner will receive. System size, approved production, utility group, project category, adders, collateral, fees, and the customer agreement all affect the result.

The word to watch is gross. The contracting utility pays the Approved Vendor. The Disclosure Form and customer agreement control what value reaches the homeowner, in what form, and on what schedule. Ask for those terms in writing before relying on a headline REC number.

When the money actually arrives

Under the Small DG schedule effective for the 2026-27 program year, the contracting utility pays 50% of the REC contract value to the Approved Vendor at energization. The remainder is paid ratably over the following six years. That is the Approved Vendor's program payment schedule; it is not automatically the homeowner's payment schedule.

Do not assume there will be a homeowner "first check." A customer may receive value through a contract-price reduction, a separate payment, or another disclosed structure. The official Illinois Shines Disclosure Form and customer agreement should match the marketing claim.

The fifteen-year REC contract also includes delivery obligations and remedies for underperformance. System removal, performance, sale of the home, and assignment responsibilities should be reviewed in the project documents rather than assumed from a general example.

Approved Vendors, Designees, and why you cannot apply yourself

Homeowners do not submit Illinois Shines applications. Only a state-registered Approved Vendor can, and that is deliberate. The Illinois Power Agency vets Approved Vendors, requires them to follow marketing and consumer protection rules, and holds them responsible for the projects they submit.

Underneath each Approved Vendor sit Designees, which are the installers and sales organizations doing the actual work under that vendor's registration. A company you talk to might be an Approved Vendor itself, or it might be a Designee working through one. Either arrangement is legitimate and common. What matters is that someone in the chain is registered, that they file your application correctly, and that your paperwork spells out exactly how the REC money flows to you.

The application happens in two parts. Part I is filed after the required documents are signed and before installation; Program approval establishes the project's applicable block and REC price. Once the system is installed, inspected, and given permission to operate by ComEd or Ameren Illinois, Part II is filed with proof of energization. The contracting utility's first program payment to the Approved Vendor follows the applicable contract process and schedule.

The Program also requires a standardized disclosure form before the customer signs the installation contract, which lays out the system, costs, and REC arrangement in a consistent format. If a company skips that form, do not sign until the issue is resolved.

Direct Solar is registered as Illinois Shines Designee D5926 for Disclosure Form and Marketing/Sales activity under Approved Vendors Tron Solar, LLC and Sunrun Installation Services Inc. The Approved Vendor for a specific project will be identified on the official Disclosure Form and agreement. The Approved Vendor, not Direct Solar Pros acting alone, submits the project and enters the REC contract.

How Illinois Shines stacks with everything else

Illinois Shines, utility rebates, and net-billing credits are separate mechanisms, but their eligibility and billing consequences can interact. Our guide to other incentives an Illinois homeowner can claim maps the full set. For example, accepting the ComEd solar rebate may affect billing treatment. Review the current utility tariff and exact proposal instead of simply adding every headline value together.

Illinois Shines is also separate from Illinois Solar for All, which has different customer eligibility, vendor obligations, and consumer protections. We cover that separately. In a lease or power purchase agreement, incentive rights and REC ownership depend on the contract and system owner. The proposal must identify who receives each benefit.

Tax treatment can depend on the transaction and customer. Direct Solar Pros does not provide tax advice; ask a qualified tax professional how any payment, discount, rebate, or REC value applies to your situation.

Questions to ask before you sign

Ask whether the company is an Illinois Shines Approved Vendor or a Designee, and which vendor the project will be submitted under. Ask what percentage of the gross REC value you receive and whether it is a direct payment or a reduction in your system price. Ask which program year the Part I application will be filed in, because REC prices and capacity are set annually and the current year's block can fill up. And ask for the standardized disclosure form before any deposit changes hands.

If you would rather have someone walk you through the numbers for your own roof, including what the REC agreement is worth in your utility territory, schedule a free consultation and bring a recent electric bill.
