Oncor Electric Delivery Company received approval from the Public Utility Commission of Texas to build the Dinosaur to Longshore 765 kV Transmission Line, a new extra-high-voltage line in West Texas. The application, filed February 19, 2026 under PUC Docket No. 59315, considered 130 alternative routes spanning approximately 235 to 270 miles.
On July 24, 2026, the administrative law judges at SOAH issued a Proposal for Decision recommending Route 559. On August 28, 2026, the Public Utility Commission of Texas approved the Dinosaur to Longshore project and adopted Route 559 as the approved route. The Dinosaur to Longshore and Longshore to Drill Hole projects, together, encompass more than 400 miles of new 765-kV transmission infrastructure stretching across West and Central Texas.
This project has generated some of the most visible landowner opposition of any case in this group, including concerns involving Dinosaur Valley State Park. The project is expected to affect approximately 550 parcels, with right-of-way activity anticipated from 2027 through 2029 and completion currently planned for 2029.
Landowner and attorney Dan Gattis can help you understand what the PUCT’s approval of Route 559 means for your property, what to expect as right-of-way activity moves forward, and how to protect your land and your rights.
