Center-Grand Forks 345 kV Transmission Line

Center-Grand Forks 345 kV Transmission Line

Scope

Michels was contracted to install approximately 250 miles of new, high voltage (345-kV) AC transmission line from the existing Center 345-kV substation at the Milton R. Young Station located about 4.5 miles southeast of the town of Center, N.D., in Oliver County, to the existing Prairie substation located on the western boundary of the city of Grand Forks, N.D., in Grand Forks County. The majority of transmission structures for the project was a single-pole, single-circuit, self-weathering tubular steel that oxidizes or rusts to form a dark reddish brown surface coating to protect the structure from further weathering. The steel single poles are placed on large concrete caisson foundations.
