PEWAUKEE, Wis. (AP) — The corporate whose underwater energy cables had been broken by an anchor strike in Michigan’s Straits of Mackinac three years in the past mentioned Monday it was starting to put in replacements.
A ship anchor in April 2018 struck three of American Transmission Co.’s six cables, which moved electrical energy between the Decrease Peninsula and the Higher Peninsula. Two had been severed and one other was critically broken.
About 600 gallons of insulation fluid leaked into the straits, a channel that connects Lake Huron and Lake Michigan.
The parts of the cables nearer to shore had been underground, whereas these in deeper waters the place the strike occurred lay on the lake flooring.
The corporate reconfigured the undamaged cables right into a single circuit so the circulation of electrical energy may proceed. However two working circuits are wanted for reliability, which the $105 million substitute venture will present, the corporate mentioned.
Ending elimination of the previous cables and laying the brand new ones will take about seven months.
“Along with our contractor companions, we’re dedicated to making sure this venture is accomplished safely and in an environmentally delicate matter,” mentioned Tom Finco, a vp of the corporate primarily based in Pewaukee, Wisconsin.
The 2 new cables, shifting a mixed 138,000 volts, will include stable insulation with no fluids.
