SPP-GEN-2017-146 is a proposed 151.8 MW wind generation project located in Castro County, Texas. The development project is entirely wind-powered, with a single wind component accounting for its full capacity. It lies within the Southwest Power Pool (SPP) region, and the interconnecting utility is Southwestern Public Service (SPS). The project's point of interconnection is the Deaf Smith–Plant X 230 kV line, and it has requested Energy Resource Interconnection Service (ERIS).
The project entered the SPP interconnection queue on November 27, 2017, and was studied as part of the DISIS-2017-002 cluster within the 05 Southwest study area. Its queue status is listed as active, and an interconnection agreement (IA) has been executed. The proposed commercial operation date is October 15, 2026. The available data does not identify a developer or a formal project name.
