Less than a year after construction began, Basin Electric has energized its newest transmission line -- the Belfield-to-Rhame line in southwest North Dakota. Construction began last May on the 74-mile, 230-kilovolt transmission line. Planning for the line began in 2007.
Bryan Keller, Basin Electric’s manager of transmission system maintenance, said the line was placed in operation at 4:44 p.m. April 7. The transmission line structures are galvanized steel, single-poles with no guy wires.
The transmission line project also included construction of a new substation south of Rhame, and expansion of an existing Western Area Power Administration substation east of Belfield.
The North Dakota Transmission Authority – through the Bank of North Dakota – financed $25 million of the $39.8-million project cost. The Authority was created in 2005 to aid in the development of new transmission lines in the state.
