SPP-GEN-2021-052 is a proposed 75 MW battery energy storage development project located in Muskogee County, Oklahoma. The project consists of a single battery storage component and would interconnect at the Pecan Creek 345kV substation within the service territory of OGE. No developer has been publicly identified in the available queue data.
The project is listed as active in the Southwest Power Pool (SPP) interconnection queue, which it entered on April 29, 2021. It is being evaluated under the DISIS-2021-001 definitive interconnection system impact study cluster, in the 04 Southeast study area. The project has requested Energy Resource Interconnection Service (ERIS), and its interconnection agreement has been executed. Its proposed commercial operation date is June 15, 2031.
