Final Block Sizes Included Reallocated Capacity from the 2024-25 Program Year and Following Capacity Awards for Waitlisted Projects

Illinois Shines features annual blocks of capacity that remain open until block capacity is exhausted for the Program Year, and unused or uncontracted capacity is redistributed after the close of a Program Year. A memo outlining the steps the Agency has taken to reallocate remaining capacity from the 2024-25 Program Year for use in the 2025-26 Program Year, and other important information, can be found here.

The following table summarizes the results of the aforementioned allocations and the amount of capacity that will be available at the 2025-26 Program Year opening on June 2, 2025. For a more detailed explanation of the calculations for the final block size and waitlist allocations please reference the Final Block Determinations Calculation Workbook on the Block Capacity Dashboard web page.

Please note that all 2025-26 TCS Group A and Group B capacity and all EEC CS Group A capacity has been awarded to projects on the 2024-25 Waitlists. All TCS projects submitted during the 2025-26 Program Year will be reviewed, scored, and added to the Waitlists if they meet the 5-point waitlist minimum score.  All EEC CS Group A projects submitted during the 2025-26 Program Year will be added to the EEC CS Group A waitlist.
