Birch Creek Energy, a St. Louis-based renewable energy company, has announced that its Earp Solar project, a 47MW utility-scale solar facility in Illinois, is now fully financed and operational.
Earp Solar: First Operational Project in Birch Creek’s IPP
Earp Solar is situated on a 229-acre (92.7 ha) site in Warren County, Illinois, and is interconnected with Ameren Illinois. The facility generates enough electricity to power more than 7,300 homes and marks the first project to become fully financed and operational within Birch Creek’s independent power producer entity (IPP), paving the way for several others scheduled to launch this year.
