Collins 345 kV (queue ID PJM-C01-1808) is a proposed 940 MW nuclear generation project in Grundy County, Illinois. The development project is being pursued by NRG Tully Energy Center LLC. It would connect to the transmission system at the Collins 345 kV point of interconnection, within the service territory of the utility ComEd.
The project is listed as active in the PJM Interconnection queue. It entered the queue on April 24, 2026, as a generation interconnection request and is being evaluated in study cycle C01. Its proposed commercial operation date is May 1, 2036. The available data does not indicate the status of an interconnection agreement for the project.
