Great Southwestern Construction Minimizes Environmental Impacts During T-Line Construction
Great Southwestern Construction successfully constructed the 144-mile Antelope Valley Station to Judson transmission line for Basin Electric Power Cooperative (Basin Electric) in North Dakota.The two-year project was designed to expand and upgrade the transmission system in the Bakken Formation, an area covering approximately 200,000 square miles that is rich with opportunity for oil and gas exploration and production.
The 345kV, single circuit line consists of direct embed monopole, 3-pole and H-frame structures, and begins in Beulah, ND, and runs west toward Grassy Butte then north to Williston. The line ties into the newly constructed Judson substation, which was also built by Great Southwestern Construction.
