New Proposed LCRA High Voltage Powerline – Leander-Round Rock Transmission Line Project (Williamson County)

The Lower Colorado River Authority (LCRA) has proposed a new high-voltage transmission line that would serve the quickly developing area between Cedar Park, Round Rock, and Leander. The new electric transmission line is expected to transmit 138,000 kilo volts of electricity (138kV).  The proposed project would cut through southwestern Williamson County, connecting two new substations to existing stations in Leander and Round Rock.


Currently, this project is in the Environmental Assessment and Routing Analysis phase. Initial route segments and substation sites are being developed. Once the alternative routes are created and evaluated, the LCRA will move forward with filing the Certificate of Convenience and Necessity (CCN). The LCRA anticipates filing the CCN application for the project with the PUC this spring.

Currently, the PUC has opened docket number 45364 to receive public input concerning the project. This docket number will be updated once the LCRA files its project application.
