SPP-GEN-2019-053 is a proposed 50 MW battery energy storage development project located in Edwards County, Kansas. The project consists of a single battery storage component with a capacity of 50 MW. It would connect to the transmission system at the Great Bend-Spearville 230 kV line, within the service territory of Sunflower Electric Power Corporation (SUNC). No developer has been publicly identified in the available queue data.
The project is in the interconnection queue of the Southwest Power Pool (SPP), which it entered on May 24, 2019. It was evaluated in the DISIS-2019-001 cluster study, in the 03 Central study area, and has requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS). The project's queue status is listed as active, and an interconnection agreement has been executed. The proposed commercial operation date is December 1, 2028.
