TL;DR
Two community solar projects on a reclaimed Illinois coal mine site have nearly 650 subscribers, including local households and institutions. The projects exemplify land reuse, grid modernization, and community access to clean energy.
Two community solar projects in Minonk, Illinois, have been commissioned on a reclaimed former coal mine site, serving nearly 650 subscribers, including residential and institutional customers. This development highlights land reuse and advances Illinois’ renewable energy goals, with significant community participation and grid modernization efforts.
The two solar projects, with a combined capacity of 9.8 MW across approximately 40 acres, are built on a site that previously extracted coal from the Colchester Coal Seam for about 75 years. They are certified brownfield sites under Illinois Shines, reflecting their role in transforming disturbed land into productive use. The projects are among the first in Illinois to incorporate Distributed Energy Resource Management Systems (DERMS), a smart grid technology that enhances grid stability by managing distributed energy resources in real time.
Nearly all available capacity has been subscribed, with over 650 individual participants. About 450 are residential customers, including approximately 200 low-income households, expanding access to clean energy savings for underserved communities. Institutional anchors include Rush University Medical Center and the College of DuPage, which together account for 40% of the energy offtake, providing stability and encouraging broader participation.
Developed by TurningPoint Energy and operated by Nexamp, this is their first collaboration in Illinois. The projects demonstrate how land previously used for coal extraction can be repurposed for renewable energy, supporting Illinois’ clean energy transition while maintaining local economic benefits.
Community Solar on Former Coal Mine Highlights Land Reuse and Grid Innovation
This project exemplifies the potential for repurposing former coal mining sites for renewable energy, supporting environmental cleanup and economic development. The high subscriber interest, including low-income households, demonstrates growing community engagement in clean energy. The integration of DERMS technology enhances grid reliability and paves the way for smarter, more resilient energy systems in Illinois, aligning with state goals for increased renewable capacity and grid modernization.

Illinois’s Transition from Coal to Renewables on Reclaimed Land
Illinois has a long history of coal mining, with many sites now being reclaimed for new uses. The Minonk projects mark a significant milestone as the first community solar developments on a certified brownfield site in Woodford County, illustrating the state’s efforts to balance energy heritage with renewable growth. This follows broader trends in Illinois to integrate renewable energy into existing infrastructure and land, supported by programs like Illinois Shines.
Previous projects have focused on large-scale solar farms, but community solar offers broader access, especially for low-income households. The use of advanced grid management systems like DERMS reflects Illinois’s commitment to modernizing its grid to accommodate increasing renewable generation, which is critical as the state aims to meet its clean energy targets.
“Standing on this former coal site today and seeing it continue its role in powering our communities is a powerful symbol of Illinois’ energy future.”

Uncertainties Over Long-Term Community Participation and Grid Impact
It is not yet clear how sustained community engagement will be over time or how the integration of DERMS will perform at scale in Illinois’s evolving grid. Additionally, the long-term economic impacts for low-income subscribers and the broader grid stability are still being evaluated as the projects operate beyond initial deployment.
Monitoring Community Engagement and Grid Performance Post-Launch
Next steps include ongoing monitoring of subscriber retention, especially among low-income households, and assessment of DERMS technology’s performance in managing grid stability. Further expansion of community solar on other brownfield sites in Illinois is expected as part of state renewable initiatives. Stakeholders will also watch for policy updates that could influence future projects.
