SPP-GEN-2025-SR4 is a proposed 150 MW battery storage project located in Kinsley, Kansas. The project is listed in the Southwest Power Pool (SPP) interconnection queue with an entry date of August 18, 2025. The proposed project's point of interconnection (POI) is the Great Bend-Spearville 230kV line.
The project, which has an active status in the queue, is being developed within the Sunflower Electric Power Corporation (SUNC) service area. It is designated as providing both Energy Resource (ER) and Network Resource (NR) service.
