The Marion County Solar Project is a proposed solar generation project with a total capacity of 99.96 MW. Located in Marion County, Ohio, the project is interconnected within the PJM Interconnection queue as entry PJM-AC2-195. The queue entry date is April 1, 2017, and the proposed commercial operation date is December 31, 2025. The interconnection agreement (IA) has been executed. The point of interconnection (POI) is the Galion-Roberts South 138 kV line.
The project is linked to the existing Marion County Solar Project operating plant (EIA ID 66860). The project has appeared in recent news coverage related to regulatory matters and deals.
