BYRON - WEMPLETOW 345 kV (queue ID PJM-C01-1235) is a proposed 175 MW battery energy storage development project in Ogle County, Illinois. The project is being developed by Acciona Energy USA Global LLC and would connect to the transmission system of ComEd, the local utility. Its point of interconnection is the Byron–Wempletow 345 kV line, from which the project takes its name.
The project is listed as active in the interconnection queue administered by PJM Interconnection, where it entered the queue on April 23, 2026, under the Generation Interconnection service type. It is currently in study phase C01, part of PJM's cycle-based interconnection process. The proposed commercial operation date is July 4, 2030. The available data does not indicate that an interconnection agreement has been executed.
