SPP-GEN-2026-SR29 is a proposed battery energy storage project located in Thomas County, Kansas, with a total capacity of 196.56 MW. The development project is within the Southwest Power Pool (SPP) region, and the associated transmission utility is Sunflower Electric Power Corporation (SUNC). The project would connect to the grid at the Mingo 115kV point of interconnection. No developer or project name has been publicly identified in the queue data.
The project entered the SPP interconnection queue on June 4, 2026, and holds an active status. It has requested Energy Resource (ER) interconnection service and has a proposed commercial operation date of October 1, 2029. The available data does not indicate the status of an interconnection agreement.
