APS-Q360 is a proposed 550 MW hybrid solar and battery energy storage project located in Maricopa County, Arizona. The project consists of 550 MW of solar photovoltaic generation. It is interconnected to the Arizona Public Service (APS) grid at the Delaney 500kV point of interconnection.
The project is listed in the APS interconnection queue as of September 30, 2020, with a proposed commercial operation date of December 1, 2023. The interconnection agreement (IA) for the project has been executed. The project is currently listed as active in the interconnection queue.
