The Illinois Power Agency’s draft 2026 Long-Term Renewable Resources Procurement Plan contains proposed REC prices for the Illinois Shines and Illinois Solar for All programs for the 2026-27 Program Year. These REC prices are calculated using the REC Pricing Model spreadsheet, which is included as Appendix E of the draft 2026 Long-Term Plan.
An error in the REC Pricing Model that impacted the calculation of modeled REC prices for the Illinois Shines Group B Traditional Community Solar program has been brought to the Agency’s attention by a stakeholder. The Agency has corrected the error, which changed REC prices for Group B Traditional Community Solar. No other category was affected by this change. An updated version of Appendix E has been posted to the 2026 Appendices page of IPA website.
