SPP-GEN-2017-230 is a proposed 72.5 MW solar generation project located in Lincoln County, Oklahoma. The development project is listed in the interconnection queue of the Southwest Power Pool (SPP), with Oklahoma Gas and Electric (OGE) identified as the interconnecting utility. The project would connect to the grid at the Tryon 138kV Substation and has requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS).
The project entered the SPP queue on November 28, 2017, and was studied as part of the DISIS-2017-002 cluster in the 04 Southeast study area. It remains in active status, and an interconnection agreement (IA) has been executed. The proposed commercial operation date is May 1, 2028.
