SPP-GEN-2025-SR27 is a proposed 50 MW battery storage project located in Roswell, Chaves County, New Mexico. The project is in the Southwest Power Pool (SPP) interconnection queue as of July 1, 2025, and is listed as an active project. The interconnecting utility is Southwestern Public Service (SPS).
The project's point of interconnection (POI) is the Chaves County 115 kV Substation. The designated service type for the project is Energy Resource (ER).
