The ATLAS COMPLEX is a proposed hybrid Solar+Battery project located in La Paz County, Arizona. The development project has a total capacity of 5120 MW, consisting of 3200 MW of solar generation and 1920 MW of battery energy storage. The project is being developed by DCRT and is interconnected within the California Independent System Operator (CAISO) region.
The project entered the CAISO interconnection queue as queue ID CAISO-1402 on May 1, 2017, with a proposed commercial operation date of January 1, 2026. An Interconnection Agreement (IA) was executed on January 10, 2021. The point of interconnection (POI) is the Delaney-Colorado River 500 kV Line. The ATLAS COMPLEX project has been the subject of recent news coverage, with 15 articles related to deals, regulatory matters, and development.
