SPP-GEN-2018-052 is a proposed 70 MW battery energy storage development project located in Lea County, New Mexico. The project consists of a single battery component and is in the interconnection queue of the Southwest Power Pool (SPP), with Southwestern Public Service (SPS) as the interconnecting utility. No developer has been publicly identified in the queue data. The project would connect to the grid at the Roadrunner 115kV Substation and has requested Energy Resource Interconnection Service (ERIS).
The project entered the SPP interconnection queue on May 29, 2018, and was studied as part of the DISIS-2018-001 cluster in the 05 Southwest study area. It remains in active status, and an interconnection agreement has been executed. The proposed commercial operation date is December 31, 2027.
