SPP-GEN-2026-SR27 is a proposed 300 MW battery energy storage development project located in Muskogee County, Oklahoma. The standalone storage project is listed in the interconnection queue of the Southwest Power Pool (SPP), with OGE identified as the associated utility. No developer name has been disclosed in the available queue data. The project would connect to the grid at the Pecan Creek 345kV Substation.
The project entered the SPP interconnection queue on June 26, 2026, and holds an active status. It has requested Energy Resource (ER) interconnection service and has a proposed commercial operation date of June 15, 2028. The queue data does not include information on the status of an interconnection agreement.
