Project

Oncor and LCRA TSC have filed an application to build a 765kV transmission line from Ward to Schleicher counties to strengthen the Texas transmission grid. The proposed line will be approximately 197 miles long and is expected to be energized by the winter of 2030, pending PUCT approval.

Deal Analysis

Oncor and LCRA Transmission Services Corporation (LCRA TSC) have announced a joint development to construct a 197-mile, 765kV transmission line in Texas, connecting Ward and Schleicher counties. The project, currently pending approval from the Public Utility Commission of Texas (PUCT), aims to bolster the state's transmission grid and is projected to be operational by winter 2030. While the deal value remains undisclosed, the involvement of Oncor, a major electric delivery company serving over 3.8 million customers, and LCRA TSC, alongside regulatory oversight from the PUCT, underscores the project's importance for grid reliability and future energy needs in Texas. This development signifies a crucial investment in Texas's energy infrastructure, addressing the increasing demand for electricity and the need for a more robust and resilient grid. The construction of a high-voltage transmission line will enhance the capacity to move power across the state, potentially unlocking renewable energy resources and improving overall grid stability. The project's success hinges on timely regulatory approvals and efficient execution by Oncor and LCRA TSC, both experienced players in the Texas energy market.
