Big Sandy-Lincoln-Midway transmission improvement project
 Tri-State is proposing to modify and upgrade the existing 79-mile Big Sandy–Lincoln–Midway 230-kilovolt transmission line. The project area includes portions of Colorado’s El Paso, Elbert and Lincoln counties.
The upgrades will occur within the existing transmission right-of-way (ROW), on an existing transmission line. The voltage and configuration will remain unchanged as a single circuit 230-kV transmission line. We propose to raise the conductor wire to provide additional ground clearance. This will involve raising some poles, replacing some poles, adding cross bracing and some cross arms on the remaining poles to increase ground clearance, and installation of an overhead optical groundwire.
This project is anticipated to be completed over a time period of approximately one year and is not related or connected to any other proposed or future transmission line projects previously identified in the region.
More detailed project information can be found at the Project Overview link below.
Project Benefits
This project would:
- Upgrade the Big Sandy–Lincoln–Midway 230-kV transmission line for operation at the higher thermal limit and increase overall structural integrity of the line.
- Increase reliability of the Tri-State transmission system.
- Decrease the economic risk of extended outages caused by catastrophic failures
Tri-State is requesting the Rural Utilities Service (RUS) to provide financial assistance for the proposed project. An Environmental Assessment (EA) will be developed, which will enable RUS to evaluate the environmental effects of the proposed project for compliance with the National Environmental Policy Act. The EA will provide a description of the project, the need for the project, alternative to the project, an analysis of the affected environment and potential effects to the natural and human environment, mitigation, and monitoring measures.
