Public Service : PSE&G Energizes Sewaren – Metuchen Reliability Project

(Newark, N.J. - Aug. 17, 2016) Public Service Electric and Gas Co. (PSE&G), New Jersey's largest utility, today announced it placed in service the Sewaren - Metuchen 230kV Conversion Project, a $125 million electric infrastructure investment needed to maintain reliability by relieving congestion on other regional transmission systems.

As part of its multi-billion dollar transmission investment portfolio, PSE&G energized the Sewaren - Metuchen project, which runs from the PSE&G switching station in Woodbridge to its switching station in Edison. Mandated by PJM Interconnection, the regional power grid operator, the project was designed to replace the existing 138,000-volt (138kV) transmission system from Woodbridge to Edison with a 230,000-volt (230kV) transmission system. The new, higher voltage line will eliminate electric system capacity issues in central New Jersey, providing better power quality in the region.

The project required overhead transmission modifications within existing PSE&G right of ways. There were major upgrades to four existing PSE&G stations, including the expansion of the Metuchen Switching Station. The existing 138kV lattice towers supporting the overhead lines were replaced with monopole structures. Existing stations were upgraded entirely within existing fence lines.

In addition to the Sewaren - Metuchen project, PSE&G energized two other strategic transmission reliability projects this summer, including the Northeast Grid Reliability Project and phase 1 of the Bergen - Linden Corridor Upgrade Project.

PSE&G invested more than $1.8 billion in electric transmission reinforcement and upgrades in 2015, part of its plan to invest $12 billion in its electric and gas infrastructure over the next five years. These investments improve the resiliency and maintain the reliability of PSE&G's system, and are a powerful stimulant of the state's economy -- supporting 6,000 jobs annually -- in the construction trades across New Jersey, and with the New Jersey-based businesses that supply the materials and resources to carry out the work.
