Public Service Electric and Gas Company (PSE&G) plans to file for approval with the New Jersey Board of Utilities to upgrade transmissions lines in New Jersey, US, in May.
Under the North Central Reliability Project, the utility plans to overhaul transmission lines and substations from existing 138kV power to 230kV power in the northern and central regions of the state.
The project, expected to cost between $300m and $350m, will maintain reliability, provide better power quality and reduce transmission system congestion in the region.
PSE&G president and CEO Ralph LaRossa said that the project is essential to meet the region's demand for electricity over the long term and ensure reliable service.
The project would upgrade existing PSE& amp;G transmission lines and stations from the Roseland Switching Station in Essex County to the West Orange Switching Station in Essex County and to the Sewaren Switching Station in Middlesex County.
The 138kV transmission lines will be replaced with 230kV lines across 35 miles through West Orange to Woodbridge.
With the approval, the utility will begin work on the upgrades in early 2012 and complete it by June 2014.
