Timberland 230kV Transmission Line and Substation Project (Liberty and Harris Counties)

Southeast Texas' population and economic opportunities continue to grow year after year. To support this growth, Entergy Texas, Inc. (ETI) has launched a project designed to bring additional power to one of the fastest growing areas in Texas. The Timberland 230kV Transmission Line and Substation Project calls for the construction of a new transmission line and new substation. The work will support and enable economic growth in Southeast Texas as well as enhance reliability for our existing and future customers.
The purpose of this project is to connect the new Timberland Substation near the community of Plum Grove in Liberty County to the existing China to Heights 230kV transmission line, in the vicinity of Eastgate and Luce Bayou.  The existing China Substation is located just west of China in Jefferson County. The Heights Substation is currently under construction and is located near Porter Heights in Montgomery County. The Heights Substation is scheduled to go into service in early 2019. Once the proposed project is completed, the transmission line and substation will provide an additional source of power for the growing developments around the expansion of the Grand Parkway, HWY 99. This new source of power will help ensure reliable service to meet the local power needs by providing a distribution service to support the area's load growth. The Timberland project will be designed to allow for the future economic development growth in the area.
There are a number of routes that the new 230kV transmission line could take between the existing China-Heights transmission line and new Timberland Substation. Potential routes, along with the various segments that they would be comprised of, are listed in this brochure along with the routing criteria used to develop them. ETI has also included the preliminary construction specifications so you will know what to expect once the project is underway and complete.
All routes and route segments included in this notice are available for selection and approval by the Public Utility Commission of Texas.
