SPP-GEN-2024-280 is a proposed 350 MW solar and battery hybrid project located in Andrews County, Texas. The project is listed as active in the Southwest Power Pool (SPP) interconnection queue, with a queue entry date of March 1, 2025. The proposed point of interconnection (POI) is the Andrews County 345 kV Substation, and the requested service type is ER/NR.
The development project consists of both solar and battery storage components, though their individual capacities are not specified. The project is interconnected with Southwestern Public Service (SPS) within the SPP region. No proposed commercial operation date or interconnection agreement (IA) status is available. The developer is not specified in the queue data.
