SPP-GEN-2019-011 is a proposed battery energy storage development project located in Yoakum County, Texas, within the Southwest Power Pool (SPP) region. The project has a total proposed capacity of 207 MW, consisting entirely of a single battery storage component. No developer is identified in the available queue data. The project is planned to interconnect at the Yoakum 345kV Substation, with Southwestern Public Service (SPS) as the associated transmission utility.
The project entered the SPP interconnection queue on April 22, 2019, and currently holds an active status. It was evaluated as part of the DISIS-2019-001 study cycle in the 05 Southwest study area. It has requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS). An interconnection agreement has been executed for the project, marking an advanced stage in the interconnection process. The proposed commercial operation date is June 1, 2028.
