Sol Systems, a clean energy project developer and independent power producer, acquired the Wolf Creek Renewable Energy Center from U.S.-based solar project developer US Solar.
Located in Saline County, Illinois, the Wolf Creek is a 250 MW solar built atop a subsurface mine and adjacent to Sol’s 342 MWdc Eldorado Solar Project.
US Solar originated and advanced the project through the early stages of development, including land acquisition, permitting, and grid connection. The company secured a conditional land use permit in September 2024.
“Wolf Creek is a natural extension of our work in Saline County,” said Andrew Grin, SVP of M&A and Strategic Partnerships at Sol Systems. “Our team has deep experience building on subsurface mine sites and has developed strong relationships within this community. We’re honored that US Solar saw our work at Eldorado and Tilden and trusted Sol to carry Wolf Creek forward. That trust reflects the strong alignment between our teams and our shared commitment to responsible, community-focused development and land stewardship.”
Wolf Creek is part of US Solar’s portfolio, progressing through the Midcontinent Independent System Operator’s DPP-2022 interconnection cycle.
Sol Systems, in March 2026, reached financial close of its 144 MWac Blossom Solar Project in Morrow County, Ohio, and the 180 MWac Nightfall Solar Project in Uvalde County, Texas. A group of lenders comprising BBVA, ING Capital, Intesa Sanpaolo, NAB, Natixis CIB, and NatWest arranged the financing.
The company also secured a $675 million revolving construction finance facility in July 2025 to support the development of its upcoming portfolio of solar and storage projects. The funding will support an initial 500 MW of projects planned in Illinois, Ohio, and Texas, with the first group of projects expected to come online by the end of 2026.
According to Mercom’s Annual and Q4 2025 Solar Funding and M&A report, approximately 37.4 GW of solar projects were acquired in 2025, compared to 37.7 GW in 2024.
