APS-Q275 is a proposed 1000 MW hybrid solar and battery project located in Navajo County, Arizona. The project consists of 1000 MW of solar capacity. Interconnection is with Arizona Public Service (APS) at the Cholla 500kV Substation.
The project is in the APS interconnection queue as of March 30, 2018, with a proposed commercial operation date of December 31, 2020. The interconnection agreement (IA) has been executed. The project has appeared in recent news coverage.
