Finally, the per megawatt rate is ultimately determined by the Block number. A specific system size is allocated for each block. The system size for the IL SREC is defined by the inverter size and is in W AC. More information on this can be found on the program FAQ. Once the system size is met based on the number of applications Illinois has received, they will close the current block and open a new block with a new and relatively lower rate. 

Info
Illinois' REC program is filled and all applications will be placed on a waitlistSighten currently has Block 5 active. If you wish to block the incentive from populating on quotes, you can find block status here.

Here's a table for reference:

What makes IL SRECs special is they offer front loads, where you can be paid 85% of the 15-year SREC value upfront on year 1 for small systems, and up to 5-year SREC value for large systems.

Sighten calculates the value of the SRECs as: Total SRECs = System Inverter Capacity kW AC * 0.1642 / 1000 kW/MW * 8760 hours/year* 15 years. From the total number of SCREs, we multiply it by the SREC rate multiplied by the 15% discount.
