SPP-GEN-2024-SR2 is a proposed battery energy storage development project located in Franklin County, Arkansas, within the Southwest Power Pool (SPP) region. The standalone storage project has a total capacity of 72.5 MW, consisting entirely of a single battery component. No developer has been publicly identified in the queue data. The project is associated with the utility OG&E and would connect to the grid at the 161 kV Branch 5 substation (Bus #515316).
The project entered the SPP interconnection queue on February 6, 2024, and currently holds an active status. It has requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS). Its study phase is listed as "Surplus; 04 SOUTHEAST," indicating that it is being processed as a surplus interconnection request in SPP's southeast study area. The project has an executed interconnection agreement (IA) and a proposed commercial operation date of March 1, 2027.
