Solar Renewable Energy Credit (SREC) Program:

  • Beginning in 2015, the Illinois Power Agency will use the Renewable Energy Resources Fund to purchase SRECs from system owners in a competitive auction
  • Systems placed in service after January 21st, 2015 will be eligible to bid in during Special Procurements in June and November of 2015; Systems already in place at that date will be eligible to bid in during the September 2015 Regular Procurement
  • Each SREC is equivalent to 1 MWh; Calculations of SRECs for each system are based on estimated annual production factor of 14.38%
  • SRECs are able to enter into 5-year contracts based on their project bid amount

For example, a 10 kW system will be eligible to bid 63 SRECs in the program using this formula:

10 kW / 1000 kW * 14.38% * 8760 * 5 yrs = 63 SRECs

* Other eligibility requirements apply to this program
