Desert Rainbow Generation Tie-Line
The Desert Rainbow Generation Tie-Line (Gen-Tie) project would interconnect the proposed Desert Rainbow Project, a photovoltaic electricity generation and battery energy storage system facility (Generation Project), to the regional transmission grid at a point of interconnection (POI) located at the existing Salt River Project (SRP) Pinal West to Jojoba 500-kilovolt (kV) transmission line.
Location
The Project would originate at the Generation Project substation, located in proximity to West Riggs Road and between South 155th Avenue and South Bullard Avenue. See the figure below for the location of Gen-Tie Project’s route options.
