About

The ROUGH HAT HYBRID SOLAR project is a proposed 404 MW hybrid solar and battery energy storage development in Nye County, Nevada. The project consists of a 204 MW solar photovoltaic array coupled with a 200 MW battery energy storage system. It is listed in the California Independent System Operator (CAISO) interconnection queue as queue ID CAISO-1650, with an entry date of April 15, 2019. The proposed commercial operation date is July 31, 2028, and the Interconnection Agreement (IA) has been executed.

The project is interconnected to the grid via the Trout Canyon Substation at 230 kV. The transmission provider is GLW. The project is currently listed as active in the CAISO queue and has appeared in recent news coverage regarding renewable energy development in Nevada.
