The Ten West Link (Ten West Link or Project), formerly the Delaney-Colorado River transmission line, is a proposed 125 mile, 500 kV series-compensated transmission line project connecting the Delaney substation in Arizona and the Colorado River substation in California. The Ten West Link will add transfer capability along the congested corridor between the Palo Verde trading hub in Arizona and load centers in southern California. The California Independent System Operator (CAISO) analyzed and approved the Delaney-Colorado River 500 kV transmission line in the 2013-2014 Transmission Planning Process (TPP) as an economic transmission project. Subsequently, following a competitive solicitation process for the Project, the CAISO selected DCR Transmission, L.L.C. (DCRT) as the Approved Project Sponsor in July 2015. The Project is scheduled to begin commercial operations in December 2021.
