About

The VIKTORIA SOLAR project is a proposed 500 MW hybrid solar and battery energy storage development in Yuma County, Arizona. The project consists of 250 MW of solar photovoltaic generation paired with a 250 MW battery energy storage system. It is located within the California Independent System Operator (CAISO) region and is interconnected to the San Diego Gas & Electric (SDGE) utility grid at the Hoodoo Wash Switchyard 500 kV point of interconnection.

The project, identified in the CAISO interconnection queue as CAISO-1435, entered the queue on May 1, 2017. Its proposed commercial operation date is June 30, 2030, and the Interconnection Agreement (IA) has been executed. The VIKTORIA SOLAR project has been the subject of recent news coverage, with at least seven articles published regarding regulatory matters and business deals related to the project.
