Jersey Central Power & Light has completed a new high voltage transmission line under Barnegat Bay, connecting towns along the barrier island of northern Ocean County to the mainland.

The submarine transmission line, one of four high-voltage lines that serve 30,000 JCP & L customers from Point Pleasant Beach to Island Beach State Park, replaces one believed to have been damaged by dredging operations, the company said.

The other three lines carried the electric charge, so there were no blackouts or brownouts due to the damaged line, a spokesperson said. “The new line helps ensure that our Barrier Island customers will have the reliable service they need during these peak summer months,” JCP & L President Jim Fakult said in a statement.

An underwater trench sled was used to bury a new high voltage transmission line in the sandy bottom of Barnegat Bay.

The line, which is made up of three cables wrapped in 28 strands of aluminum armor wire, stretches over a mile across Barnegat Bay along the Tunney-Mathis Bridges, and will improve service reliability electric, said JCP & L.

For the first time, FirstEnergy workers used a special sled to dig underwater trenches to help bury the line 10 feet below the sandy base of the bay.

Pulled by a barge along the bottom of the bay, the 12-ton sled used water jets to dig a foot-wide trench for cables.

Subsequently, the trench simply collapsed behind it, leaving only a weak depression marking the location of the line.

“This project supports our commitment to use new, innovative methods to improve service reliability by using emerging technology that places the submarine line in a safer location while minimizing the impact of the work on the fragile ecosystem of the bay, ”Fakult said.
