San Luis transmission project

WAPA issued its record of decision for the San Luis Transmission Project, April 29, 2016. For current project updates, visit the SLTP project webpage​. 

The record of decision concluded WAPA's environmental review process for the project and identified the agency preferred route and configuration for the transmission line. In 2013, WAPA proposed to construct, own, operate, and maintain a new 230-kilovolt transmission line about 62 miles in length between WAPA's Tracy Substation and WAPA's San Luis Substation and a new 70-kV transmission line about 5 miles in length between the San Luis and O'Neill Substations. WAPA also considered other transmission construction options including:

  • A new 500-kV transmission line about 62 miles in length operated at 230-kV between Western's Tracy and San Luis Substations;

  • A new 500-kV transmission line operated at 500-kV about 62 miles in length between the Tracy Substation and Pacific Gas and Electric's Los Banos​ Substation; and

  • A new 230-kV transmission line about 18 miles in length between San Luis Substation and Dos Amigos Substation.
