The proposed SPP-ERAS-2025-018 project is a 256 MW solar and battery energy storage hybrid generation project located in Portales, New Mexico. The project is in the Southwest Power Pool (SPP) interconnection queue, having entered the queue on October 2, 2025. It is currently listed as an active project in the queue.
The project intends to interconnect to the Oasis 230kV Substation and seeks Energy Resource/Network Resource (ER/NR) service from Southwestern Public Service (SPS). Specific details regarding the individual capacities of the solar and battery components are not available.
