Fall 2025 Indexed REC Procurement Results & Documents Now Available
On December 16, the Illinois Commerce Commission (ICC) approved the results of the Illinois Power Agency (IPA)’s Fall 2025 Indexed REC procurement event for RECs from utility-scale solar, utility-scale wind, and brownfield site photovoltaic projects in Illinois. Following the ICC approval, contracts were awarded to support the development of 1.58 gigawatts (GW) of new renewable generation from four utility-scale wind projects (1,100 MW) and two utility scale solar projects (488 MW). This action marks another step forward in the state’s renewable energy development.
“The IPA’s preliminary analysis shows that the Fall 2025 Indexed REC procurement achieved full market participation, enabling the successful development of new renewable projects throughout the state. Despite recent market challenges, REC strike prices for this event were comparable to Summer 2025 Indexed REC procurement event prices, inching up a tad but still demonstrating the resilience of Illinois’ renewable energy market. While the IPA anticipates that REC strike prices may increase in response to changes in the federal renewable energy landscape, the Agency has implemented two mechanisms to help address challenges stemming from recent market volatility, starting with the summer 2025 procurement: a one-time, post-award Annual Quantity Adjustment Mechanism and a one-time, post-award Inflation Adjustment Mechanism. These measures should help ensure some stability and predictability for project developers.”
In addition to the release of the comprehensive RA Study Report, the Agencies also published a comprehensive set of data files on December 22, 2025, providing the underlying inputs, assumptions, and modeling datasets used to produce the Resource Adequacy Study results. These materials are available on the Resource Adequacy Study web page, organized into a dedicated section for stakeholders to access and download.
Key takeaways from the RA Study include the following:
There are resource adequacy challenges in PJM and MISO which are likely to affect the costs and reliability of electricity supply for Illinois businesses and consumers.
There are pathways for Illinois to achieve its climate goals in the electricity sector while ensuring a reliable electric grid, using available commercialized technologies.
Illinois has the responsibility, authority, and policy tools to conduct planning, identify solutions, and support implementing actions to address these challenges.
The resultant Resource Adequacy Study includes three core components:
Executive Summary
Final Report
Appendices
Additional Releases and Stakeholder Engagement

The Agencies will host a stakeholder workshop in late January 2026 presenting the findings of the Resource Adequacy Study. That workshop will also outline next steps in support of the next phases of the study as defined in Section 9.15(o) of the IEPA Act, including the process and timeline associated with the development of a mitigation plan. Following the workshop, the Agencies will open a new request for stakeholder feedback.
