APS-Q255 is a proposed 2000 MW hybrid solar and battery project located in Coconino County, Arizona. The development project, located in the Western region, consists of 2000 MW of solar capacity. Arizona Public Service (APS) is the interconnecting utility and the entity associated with the project.
The project is in the Arizona Public Service interconnection queue (APS-Q255) with a queue entry date of May 16, 2017. The proposed commercial operation date is December 24, 2021, and the interconnection agreement (IA) has been executed. The point of interconnection (POI) is the Navajo 500kV Substation.
