sourceThe Harquahala Sunrise 2 project is a proposed 330.18 MW hybrid solar and battery energy storage project located in Maricopa County, Arizona. The development project consists of a 169.2 MW solar array coupled with a 160.98 MW battery energy storage system. The project is sponsored by DCRT.
The project is currently in the California Independent System Operator (CAISO) interconnection queue as entry CAISO-2029, with an initial queue entry date of April 15, 2021. The proposed commercial operation date is September 1, 2026. The project's interconnection status is currently in the System Impact Study phase, and the point of interconnection is the Delaney Substation 500 kV. The project has appeared in recent news coverage.
