Both participate in Illinois Shines but in different groups (ComEd = Group B, Ameren = Group A), which affects REC pricing. Both are viable for solar.

How long until Illinois Shines payment arrives?

REC payments are typically distributed annually but can have processing delays. We set clear expectations and help structure financing around realistic timelines.

Do I need an Approved Vendor?
