The proposed SPP-ERAS-2025-032 project is a 150 MW solar and battery hybrid generation project located in St. John, Kansas. The project is in the Southwest Power Pool (SPP) interconnection queue, having entered the queue on October 1, 2025. The project's point of interconnection (POI) is the St. John 115 kV Substation.
The project, under consideration by Southwest Electric Power Cooperative (SEPC), is listed as an active project in the SPP queue. It is pursuing Energy Resource/Network Resource (ER/NR) service type.
