The project identified in PJM's interconnection queue as PJM-C01-1952 is a proposed 976.1 MW natural gas-fired generation development project in DeKalb County, Indiana. The developer of record is Cortex Sycamore, LLC. The project's name and point of interconnection are both listed as "South Butler - Varner 345 kV & South Butler - Dunton Lake 345 kV #1 & South Butler - Dunton Lake 345 kV #2." This indicates the project would connect to three 345 kV transmission circuits running from the South Butler substation. The interconnecting utility is American Electric Power (AEP).
The project entered the PJM queue on April 24, 2026, under the Generation Interconnection service type. It is currently active and assigned to the C01 study phase, part of PJM's reformed cycle-based interconnection process. The proposed commercial operation date is May 31, 2031. The available data does not report the status of an interconnection agreement.
