ATC’s Straits-Pine River Line Consruction Continues

Construction continues on a 25-mi transmission line rebuild in the eastern Upper Peninsula of Michigan this summer. The Straits-Pine River line was originally built on wood poles in the 1930s. The double-circuit, 69-kV line is being rebuilt on nearly 300 new steel poles with new wires. The new line will continue to be operated at 69 kV, but has been designed to 138-kV standards should the need to upgrade the line arise in the future. The new line is being installed adjacent to the existing line, keeping power flowing between the two substations.
