A sky crane helicopter was needed to set a few transmission structures in some particularly rough terrain during construction of the Antelope Valley Station to Neset Transmission Project in western North Dakota.

Construction and reclamation efforts continue as part of Basin Electric’s Antelope Valley Station to Neset Transmission project in western North Dakota.

Work is under way on the project’s final 62 miles. Approximately 31 miles of 345-kilovolt (kV) line will be double-circuited with member cooperative Mountrail-Williams Electric Cooperative’s 115-kV line.

Foundations are 75 percent complete and nearly 10 miles of line is strung as part of the final phase's construction, according to Amanda Wangler, Basin Electric project manager III. Completion is targeted for October 2017. 

By the end of 2016, 170 miles of transmission line were completed and energized.

Reclamation work consisting of re-vegetation efforts and building approaches will resume spring 2017, from Antelope Valley Station west toward the Charlie Creek substation and north toward the Judson substation.

Crews have completed foundation work and setting structural steel as part of the new 345-kV Tande substation, located near Tioga, ND, as well as installing voltage transformers and switches.

“The contractor plans to work through the winter and complete the substation by October 2017,” Wangler said.

Modification to the 345-kV Neset substation, to be complete by fall 2017, will complete construction on the 200-mile Antelope Valley Station to Neset Transmission project.
