Tri-State transmission line upgrade complete, energized

The association's Big Sandy-Lincoln-Midway transmission line is back in service after being reconstructed to better withstand storms and wind prevalent to the area.

The association’s upgrade of its 79-mile, 230-kilovolt Big Sandy-Lincoln-Midway transmission line was recently completed and the eastern and southern Colorado power path was energized last week in time for the springtime irrigation loads that rely on its service to this largely agricultural region served by Tri-State member Mountain View Electric Association (Limon, Colo.).

During this project, approximately 56 miles of the line was upgraded from its original 1977 design. The remaining 23 miles of line was upgraded during the past five years after a series of storms damaged some of the 35-year-old structures supporting the line.

The upgraded power path also carries a new overhead optical ground wire to facilitate the G&T’s continuing efforts to improve its telecommunications system network.

The line rebuild included installation of improved transmission line structures that are designed to better withstand adverse weather conditions in this storm-prone area of the state.

Big Sandy Substation is located northeast of Limon, Colo. The line then extends south to Lincoln Substation, which is located near Tri-State’s Limon Generating Station. From that point, the line is strung along a 50-mile path to Midway Substation, located south of Fountain, Colo.
