The Illinois Power Agency (the Agency) and the Illinois Solar for All (ILSFA) Program Administrator prioritize educating and informing participants about all aspects of their decision to go solar, including the significant financial commitment of solar installation. This includes Approved Vendors or their Designees providing participants with relevant information about net metering or other crediting approaches.

Historically, Illinois utilities have been required to provide customer bill credits for excess energy produced by their residential or small commercial solar project at the full retail rate, but under the state’s Climate and Equitable Jobs Act (“CEJA”), net metering offerings will change to supply-only starting January 1, 2025. This means that for participants interconnecting renewable energy systems to the grid in ComEd, Ameren Illinois, or MidAmerican territories after December 31, 2024, full retail rate net metering will no longer be available. Participants will be credited for excess electricity that their solar project sends to the grid at their electricity supply rate rather than the full retail rate.

ComEd and Ameren Illinois have announced that all required documentation (Certificate of Completion or Witness Test Request) must be received by the utility no later than 5 p.m. C.T. on December 13, 2024, in order to be assured eligibility to receive full retail-rate net metering. The Agency has created Frequently Asked Questions (“FAQs”) to provide information to Approved Vendors, Designees, and participants about the changes. Further updates will be shared about any potential changes to the ILSFA program as more is learned about the coming rate changes.
