POWER honored for South Jersey Energy Grid Project

Rebuilt transmission line strengthens power reliability and fortifies system against storms

HAILEY, Idaho (Feb. 7, 2019) ‒ The New Jersey Alliance for Action recognized POWER Engineers Incorporated (POWER) and other partners last week for its role in rebuilding a major transmission line and increasing reliability in southern New Jersey. Atlantic City Electric contracted POWER to rebuild the 41-mile-long transmission line, which was honored with the New Jersey’s Leading Infrastructure Projects Award on Feb. 6.

The award highlights innovative, pioneering and landmark construction initiatives that greatly affect the state’s economy and honors the businesses and organizations that work together as partners to ensure the project’s success. In 2018, POWER received similar recognition from the Alliance for its work on a major 345 kV underground transmission project in the state.

The recognized project includes transmission system enhancements that traverse five counties and 13 municipalities through approximately 41 miles of southern New Jersey. The project consists of constructing a new 230 kV line from the Orchard substation in Salem County to the Cardiff substation in Atlantic County and rebuilding a series of 138 kV lines connecting substations from Upper Pittsgrove Township in Salem County to Egg Harbor Township in Atlantic County. POWER’s transmission line engineering design services replaced existing double-circuit, steel-lattice towers with new steel monopoles, and overhead-to-underground transition structures. POWER’S design calls for lines on one side of the poles to transmit 138 kV and on the other side 230 kV, providing increased power capacity to benefit area customers.

The new steel transmission poles have a smaller footprint than the lattice towers and less of an environmental impact. POWER’s design also called for drilled pier and vibratory caisson foundations. For one area of the project that couldn’t be accessed by drill rigs, concrete trucks or cranes, crews installed vibratory caisson foundations by helicopter. The use of the helicopter provided a more efficient and safer option for crews when access to energy infrastructure was limited.
