The ROUGH HAT 3 development project is a proposed 614 MW hybrid solar and battery energy storage system located in Clark County, Nevada. The project consists of 307 MW of solar photovoltaic generation paired with 307 MW of battery storage. It is listed in the California Independent System Operator (CAISO) interconnection queue under queue ID CAISO-2150.
The project entered the CAISO queue on April 15, 2021, and has a proposed commercial operation date of September 15, 2028. Its interconnection status is currently in the System Impact Study phase. The point of interconnection is the Trout Canyon Substation at 230 kV. Recent news coverage has discussed the project.
