SPP-GEN-2026-SR23 is a proposed 200 MW battery energy storage development project located in Johnston County, Oklahoma. The project is listed in the interconnection queue of the Southwest Power Pool (SPP), the regional transmission organization serving the area, with OGE identified as the associated utility. No developer name is included in the available queue data. The project would connect to the grid at the Bison 345kV Substation, its designated point of interconnection.
The project entered the SPP interconnection queue on June 22, 2026, and currently holds an active status. It has requested both Energy Resource (ER) and Network Resource (NR) interconnection service, and its proposed commercial operation date is September 30, 2028. The available data does not indicate the status of an interconnection agreement.
