Oncor Electric Delivery Company LLC (Oncor) is proposing to construct a new 765 kilovolt (kV) transmission line from Oncor’s proposed Dinosaur Switch, near Glen Rose to to Oncor’s existing Longshore Switch near Forsan in Howard County. The line is expected to be 235-270 miles depending on which route is used.
Multiple routes are proposed including two that could impact northern Brown County. Public meetings were held in Big Spring, Sweetwater and Stephenville during the week of June 2nd.
An application for the transmission line proposal will be sent to the Public Utility Commission of Texas (PUCT) by the end of December 2025 where the commission will vote to approve or deny the project and route. If approved, Oncor will then begin to acquire land right-of-way easements with construction planned to begin sometime in 2027.
According to Oncor, these preliminary alternative route links are subject to modification based on information received at the public participation meetings and further studies.
Detailed maps of the proposed route have not been made available on the company’s website as of publication date. For more information contact Christine Williams at Oncor at (214) 486-5841 or email transmissionprojects@oncor.com. For more information, www.oncor.com/transmissionprojects.
