North Lamar Transmission Line Upgrade

Justin Lane Substation to McNeil Substation

Ensuring Safe, Reliable Electric Service to Our Community

To serve the rapid growth and development taking place throughout the city, Austin Energy is upgrading the transmission line that primarily parallels North Lamar Boulevard from the Justin Lane Substation south of Morrow Street to Wagon Trail Road near Braker Lane. The upgrade project will also cross Braker Lane into the North Park Estates and Gracywoods neighborhoods

Upgrading Transmission Lines

Much of the transmission infrastructure that is being replaced as part of this project is more than 50 years old. It is being upgraded with safer, more reliable, and higher capacity infrastructure.

This project is part of a systemwide upgrade by Austin Energy in all geographic areas of the Austin community. Austin Energy is upgrading the voltage capacity of its older 69 kV transmission lines and infrastructure to 138 kV to help serve Austin well into the 21st century. The upgraded lines will have increased capacity and improved efficiency, and ultimately will lower costs for customers.
