The proposed project would be constructed by the utilities and include the following components:
Tri-State and PSCo are proposing to use a combination of steel lattice structures and steel mono-poles. The choice of structure type would be based on location and design conditions (i.e. mountainous vs. flat terrain). The line would also use low corona hardware to minimize audible noise.
Construction would be completed in several phases: access development, staging structures, foundation construction, framing and erecting the structures, stringing conductor, clean up and reclamation. Several work phases may be in progress simultaneously at different locations along the alignment. Construction of the transmission line is expected to last approximately 18 to 24 months.
