IL Solar Farms (> 200 MW)

Utility-scale solar farms—sometimes called solar parks—are central to the U.S. clean-energy transition, delivering hundreds of megawatts of renewable power to the grid while reducing dependence on fossil fuels. Increasingly paired with battery energy storage systems (BESS) and, in some regions, wind generation, these large installations provide grid stability, enable microgrid resilience, and support the broader electrification of transportation, industry, and digital infrastructure.

Beyond energy production, these projects stimulate local economies in IL state by generating construction and maintenance jobs, creating tax revenue, and supporting adjacent industries. They are also key assets in achieving state renewable portfolio standards (RPS), corporate sustainability targets, and national clean-energy commitments.

As deployment accelerates, solar farms will remain a cornerstone of America’s energy transformation—enabling a more resilient, distributed, and sustainable electricity system.
