SPP-GEN-2026-SR10 is a proposed 150 MW battery storage project located in Spearman County, Texas. The project is listed in the Southwest Power Pool (SPP) interconnection queue with an entry date of January 14, 2026. The proposed point of interconnection (POI) is the Hitchland 345kV substation. The project's service type is listed as Energy Resource (ER) and its status is active.
The development project is under consideration for interconnection to Southwestern Public Service (SPS), a utility operating within the SPP region. No information is available regarding the developer or a proposed commercial operation date. The project has not appeared in recent news coverage and is not linked to an existing operating plant in the Energy Information Administration (EIA) database.
