The proposed project TSGT-GI-DISIS-2021-10 is a 398 MW hybrid solar and battery energy storage system located in Converse County, Wyoming. The project, developed by Tri-State Generation and Transmission Association (TSGT), consists of 199 MW of solar photovoltaic generation and 199 MW of battery storage.
The project is currently in the Tri-State Generation and Transmission Association interconnection queue, with an original queue entry date of May 28, 2021. The interconnection agreement status is currently listed as suspended, effective June 1, 2023. The point of interconnection is the DJ-LRS 230kV Line.
