Underground Line Replacement Enhances Service Reliability for JCP&L's Barrier Island Customers

Rhea-AI Summary

JCP&L, a FirstEnergy Corp. (NYSE: FE) subsidiary, is undertaking a $12.5 million project to replace an underwater high-voltage power line serving New Jersey's barrier islands. The new 34.5-kilovolt line will be one of four power sources serving over 13,000 customers across multiple beach communities.

The project involves installing a 7,500-foot submarine cable using an environmentally friendly 12-ton sled that creates minimal disruption to aquatic life. The sled uses water jets at 150 PSI to create a trench one foot wide and over 10 feet deep. A barge will transport the cable equipment while pulling the sled at speeds up to 10 feet per minute. The project is expected to be completed by mid-December.

HOLMDEL, N.J., Nov. 22, 2024 /PRNewswire/ -- Jersey Central Power & Light (JCP&L), a subsidiary of FirstEnergy Corp. (NYSE: FE), is replacing an underwater, high-voltage power line to enhance service reliability to New Jersey's barrier islands. The $12.5 million project is expected to be completed in mid-December.

Once in service, the new 34.5-kilovolt line will be one of four high-voltage power sources crossing the Barnegat Bay to serve more than 13,000 JCP&L customers on the barrier islands, including the communities of Point Pleasant Beach, Bay Head, Mantoloking, Normandy Beach, Brick, Lavallette, Dover/Toms River, Ortley Beach, Seaside Heights, Seaside Park, Berkeley and Island Beach State Park.

Doug Mokoid, FirstEnergy's President, New Jersey: "The replacement of this high-voltage line offers service-enhancing redundancy into our barrier island system and delivers the power capacity that the local communities require when the population swells in the summer months. Completing this work in an innovative, environmentally sensitive manner is also important to us."

A new 7,500-foot submarine cable will be installed using a special 12-ton sled that is designed to be environmentally friendly and cause minimal disruption to aquatic life. This sled, which is about the size of a school bus, will use water jets to create a trench. The jets will shoot water at a pressure of 150 pounds per square inch to create a trench that is one foot wide and more than 10 feet deep, allowing for the installation of the new cables.

A large barge will transport heavy reels of armored submarine cable and equipment while pulling the sled at speeds of up to 10 feet per minute. As the sled moves along the bay floor, the trench collapses behind it, leaving a shallow depression to mark the cable's location.

JCP&L serves 1.1 million customers in the counties of Burlington, Essex, Hunterdon, Mercer, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex, Union and Warren. Follow JCP&L on X @JCP_L, on Facebook at facebook.com/JCPandL or online at jcp-l.com.
