SPP-GEN-2018-089 is a proposed 196 MW wind generation project located in Castro County, Texas, within the Southwest Power Pool (SPP) region. The development project would interconnect to the transmission system of Southwestern Public Service (SPS) at the Newhart 230kV Substation, which serves as its designated point of interconnection. No developer has been publicly identified in the queue data, and the project consists of a single wind component rated at the full 196 MW.
The project entered the SPP interconnection queue on November 21, 2018, and remains in active status. It was studied as part of the DISIS-2018-002 definitive interconnection system impact study cluster, within the 05 Southwest study group. The project has requested Energy Resource Interconnection Service (ERIS) and has an executed interconnection agreement (IA) with SPP. Its proposed commercial operation date is March 1, 2028, roughly nine years after its original queue entry.
