Oncor, LCRA TSC File Application to Build 765kV Transmission Line From Schleicher to Bell Counties

Why It Matters

The project addresses Texas’ escalating electricity demand and strengthens the state’s grid resilience, positioning the region to meet future load growth efficiently. Its approval would mark a critical step toward modernizing transmission capacity across the ERCOT market.

Key Takeaways

• Oncor and LCRA TSC filed CCN for 765 kV line Schleicher‑Bell.
• Project part of Texas STEP, one of four 765 kV lines.
• PUCT decision expected September; line could be energized by 2030.
• 765 kV line offers higher efficiency and lower land use than 345 kV.
• Public outreach reached thousands; landowners within 500 ft will be notified.

Pulse Analysis

Texas’ electric grid is confronting unprecedented demand spikes driven by population growth and the rise of data‑center and renewable‑energy projects. The state’s Strategic Transmission Expansion Plan (STEP) was crafted to pre‑empt bottlenecks by deploying next‑generation, high‑voltage corridors that can move bulk power across long distances with minimal losses. By introducing 765 kV lines—already commonplace in the broader U.S. and Canada—STEP seeks to reduce reliance on a patchwork of lower‑voltage assets that strain right‑of‑way availability and increase operational costs.

The recent Certificate of Convenience and Necessity filing by Oncor and LCRA Transmission Services Corporation signals the first formal regulatory step for the Schleicher‑to‑Bell corridor. The application bundles an environmental assessment, routing studies, and a record of extensive community outreach that gathered feedback from thousands of residents. Landowners within 500 feet of any proposed alignment will receive detailed notices, ensuring they can participate as intervenors or protestors. The Public Utility Commission of Texas will evaluate multiple route alternatives, weighing technical feasibility, environmental impact, and stakeholder input before issuing a final decision, expected in September.

Should the project receive approval, the 765 kV line could be operational by 2030, delivering a high‑capacity conduit that improves transmission efficiency, lowers per‑megawatt land consumption, and enhances system flexibility. For utilities, the line offers a cost‑effective path to meet ERCOT’s reliability standards without the need for extensive new low‑voltage infrastructure. Moreover, the development aligns Texas with national transmission trends, potentially attracting further investment in renewable generation that depends on robust, long‑haul transmission corridors. The initiative therefore represents a pivotal advancement in the state’s effort to secure a resilient, future‑ready power grid.
