SPP-GEN-2022-098 is a proposed 200 MW solar generation project located in Johnston County, Oklahoma. The development project is listed in the interconnection queue of the Southwest Power Pool (SPP), with OGE identified as the associated utility. No developer has been publicly identified in the queue data. The project consists of a single solar component with a capacity of 200 MW and is proposed to connect to the grid at the Bison 345kV Substation. It has requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS).
The project entered the SPP queue on December 6, 2022, and currently holds an active status. It is being evaluated as part of the DISIS-2022-001 definitive interconnection system impact study cluster, within the 04 Southeast study area. As of the latest data, its interconnection agreement status is at the Facility Study stage, and no executed interconnection agreement has been reported. The proposed commercial operation date for the project is May 1, 2029.
