About

TSGT-GI-DISIS-2021-11 is a proposed 300 MW hybrid Solar+Battery project located in Las Animas County, Colorado. The project, developed by Tri-State Generation and Transmission Association (TSGT), consists of a 200 MW solar array coupled with a 100 MW battery energy storage system. It is interconnected to the Walsenburg-Gladstone 230kV Line.

The project entered the Tri-State Generation and Transmission Association interconnection queue on May 28, 2021. Its interconnection status is currently listed as "suspended," and its Interconnection Agreement (IA) status is also "suspended." The project has appeared in recent news coverage.
