About the Project
The Bergen to Linden Corridor Upgrade Project is a $1.2 billion investment [see Forward Looking statement] to build a 345kV transmission system running from PSE&G’s Bergen Switching Station in Ridgefield, NJ to its Linden Switching Station in Linden, NJ.
Mandated by PJM Interconnection, the regional transmission organization (RTO) responsible for planning the transmission system in all or parts of 13 states, including New Jersey, the project is designed to replace the existing 138kV transmission system from Bergen to Linden with a double circuit 345kV transmission system. PJM determined that this new transmission system is necessary to ensure reliable electric service, eliminate anticipated transmission constraints, and respond to PJM/Federal Energy Regulatory Commission (FERC)-mandated infrastructure expansion. The project will eliminate electric system capacity issues in Northern New Jersey, providing better power quality in the region. On December 11, 2013, PJM assigned construction responsibility for the project to PSE&G.
The project will be separated into three phases and will require overhead transmission modifications within existing PSE&G right of ways, as well as underground cable replacements and new 345kV cable routes. There will be major upgrades to 9 existing stations, and the construction of a new switching station at Newark Liberty International Airport. The route and stations extend through seven municipalities in Bergen, Hudson, Essex, and Union Counties, including Ridgefield, North Bergen, Jersey City, Bayonne, Newark, Elizabeth, and Linden. The existing 138kV lattice towers supporting the overhead lines will be replaced with monopoles or new lattice towers, depending on design conditions, material lead times, and permit conditions. The underground transmission lines will be using a combination of new and existing conduits, and existing stations will be upgraded almost entirely within existing fence lines.
PHASE 1: Marion – Bergen 345kV Conversion Overhead
Phase 1 focused upon work to be performed within the PSE&G Hudson-Bergen/Marion-Bergen 230kV and 138kV overhead transmission corridor, and the Bergen, North Bergen, Homestead, Penhorn, and Marion stations. Construction of Phase 1 commenced in Q3 2014 and was placed in-service in June 2016.
PHASE 2: Linden - Bayway 345kV Conversion Overhead
Phase 2 will focus upon work to be performed within the PSE&G Linden-Bayway 138kV overhead transmission corridor, and the Linden and Bayway stations, with an anticipated in-service date of June 2017.
PHASE 3: Bayway - Marion 345kV Conversion Underground
Phase 3 will focus on work to be performed upon the facilities interconnected by underground cable, looping together the Bayway, North Avenue, Newark Airport, Bayonne and Marion stations, with an anticipated in-service date of June 2018. The underground system will serve to loop together the facilities upgraded in Segment 1 and Segment 2 of the project.
