SPP-GEN-2018-071 is a proposed 151 MW battery energy storage development project located in Kay County, Oklahoma. The standalone storage project consists of a single battery component rated at 151 MW. No developer has been publicly identified in the available queue data. The project is planned to interconnect into Oklahoma Gas and Electric's (OG&E) Ranch Road 345 kV substation by tapping a 0.1 gen-tie line into the existing Frontier II gen-tie line. The interconnecting utility is OGE.
The project entered the Southwest Power Pool (SPP) interconnection queue on October 25, 2018, and remains in active status. It was studied in the DISIS-2018-002 cluster within the 04 Southeast study area, and it has requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS). An interconnection agreement has been executed for the project. Its proposed commercial operation date is December 31, 2027.
