Data update
Published on Jun 10, 2025 by Derek Eder
As of June 10, 2025, an additional 52 megawatts (MW) of solar have been energized in the State of Illinois, bringing the total to 4,700 MW.
In a reversal from last month, the planned Large Distributed Generation (Large DG) category was reduced by 1,415 MW. Unclear if this was a data issue or something else. The total planned kW is about where it was in May 2025.
