Construction is underway on the three phases of Public Service Electric and Gas’ (PSE&G) Bergen to Linden Corridor Upgrade Project, a company spokesperson told TransmissionHub on Feb. 5.
Construction of Phase 1 began in 3Q14 (August), construction of Phase 2 began in 3Q15 (July), and construction of Phase 3 began in 1Q16 (January), the spokesperson said.
As noted on the company’s website, the project involves a $1.2bn investment to build a 345-kV transmission system running from PSE&G’s Bergen switching station in Ridgefield, N.J., to its Linden switching station in Linden, N.J.
Mandated by PJM Interconnection, the project is designed to replace the existing 138-kV transmission system from Bergen to Linden with a double-circuit 345-kV transmission system, PSE&G said. PJM determined that the new transmission system is necessary to ensure reliable electric service, eliminate anticipated transmission constraints, and respond to PJM/FERC-mandated infrastructure expansion, the company said.
The project will eliminate electric system capacity issues in northern New Jersey, providing better power quality in the region, according to the company, which also noted that PJM in December 2013 assigned construction responsibility for the project to PSE&G.
The project will require overhead transmission modifications within existing PSE&G right of ways, as well as underground cable replacements and new 345-kV cable routes, the company said. There will be major upgrades to nine existing stations, and the construction of a new switching station at Newark Liberty International Airport, the company noted.
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, according to PSE&G.
The existing 138-kV 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 company said, adding that the underground transmission lines will use a combination of new and existing conduits, and existing stations will be upgraded nearly entirely within existing fence lines.
The company noted that Phase 1 will focus upon work to be performed within the PSE&G Hudson–Bergen/Marion–Bergen 230-kV and 138-kV overhead transmission corridor, and the Bergen, North Bergen, Homestead, Penhorn, and Marion stations.
The spokesperson noted that Phase 1 is on schedule for an in-service date of next June.
The company noted that Phase 2 will focus upon work to be performed within the PSE&G Linden–Bayway 138-kV overhead transmission corridor, and the Linden and Bayway stations.
The spokesperson said that Phase 2 is on schedule for an in-service date of June 2017.
PSE&G said that 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. The underground system will serve to loop together the facilities upgraded in Segment 1 and Segment 2 of the project, the company said.
The spokesperson noted that Phase 3 is on schedule for an in-service date of June 2018.
