Wempletown 345 kV (queue ID PJM-C01-2112) is a proposed 250 MW solar generation project in Winnebago County, Illinois. The development project is sponsored by Gemini Solar LLC and would connect to the transmission system operated by PJM Interconnection at the Wempletown 345 kV point of interconnection, located within the service territory of the utility ComEd. The project is designated as a Generation Interconnection service request.
The project entered the PJM interconnection queue on April 24, 2026, and is listed with an active status. It is part of PJM's Cycle 1 (C01) study phase under the reformed interconnection process. The project has a proposed commercial operation date of December 31, 2029. The available data does not indicate whether an interconnection agreement has been executed. The project is not linked to an existing operating plant in EIA records, and no recent news coverage of it has been identified.
