Damaged Power Cables Replaced in Straits of Mackinac

American Transmission Co. has started repairing damaged cables in the Straits of Mackinac.

The underwater power cables were damaged by a ship anchor back in 2018.

Two cables were cut in half and another was damaged, leaking out about 600 gallons of insulation fluid into the straits.

It will take about seven months to lay new cables and remove the old ones.
