SPP-GEN-2024-178 is a proposed 199 MW battery storage project located in Harrison County, Texas. The project is in the Southwest Power Pool (SPP) interconnection queue, with a queue entry date of March 1, 2025. The proposed project, which will interconnect at the Pirkey 138 kV Substation, is currently listed as active in the queue and is being developed within the AEP utility service area.
The project's service type is listed as ER/NR, indicating it is seeking both Energy Resource and Network Resource interconnection service. The technology detail specifies "Battery/Storage / Battery". There is no information available regarding a proposed commercial operation date, interconnection agreement status, developer, or news coverage.
