The proposed solar project TSGT-GI-DISIS-2021-06 is a 140 MW solar generation facility located in Montezuma County, Colorado. The project is being developed by Tri-State Generation and Transmission Association (TSGT). It is currently active in the DISIS queue of the Transmission System Group of the West region, having entered the queue on May 27, 2021. The interconnection agreement (IA) for the project has been executed.
The point of interconnection (POI) for the project is the Main Switch 115kV Substation. Recent news coverage has discussed the development project.
