Willow Creek — Hicks 345 kV Transmission Line Project

Texas is continuing to increase the integration of renewable energy into the Texas electric market. Reliable electric facilities must be in place to support the increased levels of renewable energy and to provide efficient means for this power to reach electric consumers. As part of this on-going process, Oncor is proposing this project that consists of building approximately 40 miles of double circuit electric transmission line.

The proposed project will connect the existing Willow Creek Switching Station in southwest Wise County to the proposed Hicks Switching Station in northwest Tarrant County.

This project has been recommended by the Electric Reliability Council of Texas (ERCOT) to ensure continued safe and reliable electric service to the State due to the increased integration of electric energy generated by wind production facilities. Completion of the project will enable the new transmission system to efficiently move wind-generated electric power to market and will add valuable capacity to the entire transmission system.

• Voltage and Structure Type - The project is proposed to be a 345 kV transmission line constructed on Lattice Steel V Towers.
