Entergy Texas has plans for new transmission line in Montgomery and Walker Counties, Texas. Entergy has begun the filing process with the Public Utility Commission of Texas. This line is part of the Western Regional Economic Project designed to help support population growth in Texas. The new 230 kV transmission line is expected to be constructed by mid-2020 between the Lewis Creek Substation near Willis, Texas with one of the endpoints as either: A new Rocky Creek Substation west of Huntsville, Texas or a new Quarry Substation north of Huntsville, Texas. The new Rocky Creek or Quarry to Lewis Creek will require approval from the Public Utility Commission of Texas through a Certificate of Convenience and Necessity application. Currently, they are still debating the route option. You can check the possible routes here.
