Lambertville

The Roseland – Pleasant Valley Project (RPV) is a $546 million investment designed to strengthen the electric transmission system by replacing older transmission facilities between PSE&G’s Roseland Switching Station in Roseland and its Pleasant Valley Switching Station in Hopewell. On average, these transmission facilities are approximately 90 years old. PSE&G completed a routine maintenance assessment and determined that the existing conditions of the towers showed signs of deterioration and are an issue that need resolution.

Authorized in April 2018 by PJM Interconnection (PJM), the regional transmission organization responsible for planning the transmission system in all or parts of 13 states, including New Jersey, the 52-mile project replaces existing lattice towers and associated infrastructure that are reaching the end of their useful life. The existing lattice towers will be replaced with new, taller Y-frame monopoles and H-Frame structures. The increased height of the replacement structures is largely due to the National Electrical Safety Code® (NESC®), as well as current construction standards. Although the Y-frame monopoles are taller than the existing lattice towers, they occupy a smaller footprint on a single foundation.  The voltage of this transmission system is remaining the same (230 kV).

The PSE&G transmission ROW through the City of Lambertville spans approximately 1 mile and maintains a consistent width of 150 feet wide.  The transmission corridor runs in a northeasterly to southwesterly direction and is bound by West Amwell to the northeast and the Delaware River to the southwest.

General Schedule of Construction

The segment of the project spanning Lambertville entails the replacement of three (3) existing lattice towers with two (2) Y-frame monopoles and one (1) H-frame structure, all of which will remain within the existing ROW. The heights of the existing lattice towers that encompass the project in Lambertville range from approximately 117.5 feet to 139.5 feet and the proposed heights of the new structures will range from approximately 135 feet to 185 feet.

NOTE: Construction schedule information is tentative and subject to change based on several factors, including weather and field conditions.

Q3 2017 thru Q4 2019

You may see our crews on the right-of-way performing geotechnical work and verifying subsurface conditions and underground utilities.  In addition, you may see construction activities to support the replacement of the electric infrastructure. Safety is our highest priority at PSE&G, and it is essential that you and anyone occupying your property refrain from going on the right-of-way during these activities.
