Jersey Central Power & Light (JCP&L), a subsidiary of First Energy, has completed the upgrade of electrical infrastructure projects that were damaged in Hurricane Sandy.

The company said the upgrades and installation work cost over $15m to improve the electric service reliability for its customers.

JCP&L has completed projects across northern and central New Jersey service areas, including rebuilding transmission lines, upgrading substation equipment, and rebuilding infrastructure and reconnecting service to homes on the barrier islands that were damaged during the storm.

Jersey Central Power & Light Operations vice president Anthony Hurley said, "With customers using more electricity during the summer months, we focus on completing major repairs and conducting ongoing maintenance prior to June 1."

The company rebuilt the Whippany-Roseland 230kV transmission line and replaced 19 towers for $12m, reconnected services to about 30,000 customers in Monmouth and Ocean counties, and reconstructed 34.5kV transmission line in Sussex County.

In addition, the company upgraded equipments at substations in Colts Neck and Neptune in Monmouth County, installed new poles to extend a distribution line and create a new connection point in Riverdale in Morris County, and installing protective devices for the Oyster Creek Substation in Ocean County.

It also replaced utility poles, installed animal guards, wire, fusing, and other equipment as part of circuit upgrades, installed equipment on additional circuits, and replaced underground cable.
