San Luis Transmission Project

2022 Project Update: Western Area Power Administration (WAPA) will not be moving forward with executing the agreements necessary to implement the San Luis Transmission Project (SLTP).  The SLTP Proponent(s) were not able to achieve financing, and therefore, WAPA has cancelled work on the SLTP. The SLTP has also been removed from WAPA’s OASIS queue.​

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:
