SPP-ERAS-2025-004 is a proposed 779 MW natural gas-fired generation project located in Harrah, Oklahoma. The project, utilizing combined cycle thermal technology, is being developed within the Southwest Power Pool (SPP) interconnection queue under queue ID SPP-ERAS-2025-004. The project's point of interconnection (POI) is the Horseshoe Lake 138kV Substation.
The project, with Oklahoma Gas & Electric (OGE) as the utility, entered the SPP queue on September 30, 2025. The service type requested is ER/NR, indicating Energy Resource / Network Resource interconnection service. The project's current status within the SPP queue is listed as active.
