Winfield - WinnsboroTransmission Improvements Project

The Winfield - Winnsboro Transmission Improvements Project involves rebuilding approximately 35 miles of 69-kilovolt transmission line. The line was constructed more than 70 years ago and has reached the end of its planned service life. The project replaces deteriorating wooden poles, strengthens the local power system, and decreases the severity and likelihood of wide, community-sustained power outages.

Spring 2025: SWEPCO representatives invite you to attend an in-person open house on Tuesday, March 11, 2025 from 5-7 p.m. at First Baptist Church Mount Vernon (319 Kaufman St. S, Mount Vernon, TX 75457). 

Landowners are welcome to attend the open house to view detailed maps and learn more about the project, the construction process and SWEPCO’s vegetation management program. There is no formal presentation, so you can arrive at any time during the event. 

The project involves:

• Rebuilding approximately 28 miles of the 69-kilovolt Winfield - Winnsboro transmission line
• Rebuilding about 7 miles of the 69-kV transmission line connecting the Winfield Winnsboro power line to a substation east of Mount Vernon
• Upgrading equipment at area substations.
