SPP-GEN-2026-SR35 is a proposed battery energy storage project in Paducah, Texas, with a total capacity of 252 MW. The project is in the interconnection queue of the Southwest Power Pool (SPP), and its host utility is Southwestern Public Service (SPS). No developer is identified in the available queue data. The project would connect to the grid at the Tuco-Oklaunion 345 kV transmission line.
The project entered the SPP queue on August 26, 2026, and its queue status is listed as active. It has requested both Energy Resource (ER) and Network Resource (NR) interconnection service. The proposed commercial operation date is June 30, 2028. The available data does not report an interconnection agreement status.
