SPP-GEN-2024-GR1 is a proposed 492 MW natural gas-fired generation project located in Oklahoma County, Oklahoma. The development project is listed in the interconnection queue of the Southwest Power Pool (SPP), with OG&E identified as the associated utility. The project's proposed point of interconnection is the Horseshoe Lake 138kV substation, and it has requested Energy Resource Interconnection Service (ERIS).
The project entered the SPP queue on January 8, 2024, and currently holds an active status. It is categorized under the study phase "Replacement; 04 SOUTHEAST," indicating it is being processed through SPP's replacement generation pathway in the southeast study area. An interconnection agreement (IA) has been executed for the project, and its proposed commercial operation date is December 31, 2026.
