Western Region Economic Project

Description: This project in Entergy Texas is composed of two projects that work together to reduce congestion in the Entergy Texas transmission system.  

The two projects are (1) Construct a new 230kV transmission line from Rocky Creek to the Lewis Creek generating station.  (2) Upgrade the existing 25 mile 138 kV line from Newton Bulk to Leach.

Estimated Projects Costs:

(1)    Rocky Creek to the Lewis Creek 230 kV Construction Cost: $125 million
(2)    Newton Bulk – Leach 138 kV Upgrade Construction Cost: $20 million
 
Benefits: The purpose of this project is to upgrade the electric transmission system to more effectively move lower-cost power into and within the southeast Texas area for all customers served from Entergy Texas' transmission system.
