Repowering North-Central Austin

Ensuring Safe, Reliable Electric Service to Our Community

Transmission Poles Gracywoods

In order to serve the rapid growth and development taking place in North Austin, Austin Energy will upgrade the 811 transmission circuit along 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. 

Current Infrastructure is Outdated

Austin Energy is upgrading the voltage capacity of its older 69 kV transmission lines and infrastructure to 138 kV. In addition to increased capacity, the upgraded lines improve efficiency and ultimately lower costs for customers.

Much of the transmission infrastructure that is being replaced on the 811 transmission circuit project is more than 50 years old. It is being upgraded with a modern, and more safe and reliable infrastructure.

This project is one part of a system-wide upgrade by Austin Energy in all geographic areas of the Austin community. The upgrades will help serve the Austin community well into the 21st century.

Project Location

The 4-mile-long, 811-transmission circuit-upgrade starts at the Justin Lane Substation on North Lamar Blvd. and proceeds north along Lamar crossing at Wagon Trail Road. From there the circuit traverses the North Park Estates and Gracywoods neighborhoods until it reaches the McNeil Substation on Knollpark Drive.
