Florham Park

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 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 structures 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 Borough of Florham Park spans approximately 1 mile and maintains a consistent width of 225 feet to accommodate two side-by-side transmission systems.  The transmission corridor runs in a northeasterly to southwesterly direction and is bound by the Livingston Township to the northeast and the Borough of Chatham to the southwest.

General Schedule of Construction

The segment of the project spanning Florham Park entails the replacement of six (6) existing lattice towers with six (6) Y-frame monopoles, all of which will remain within the existing ROW, with no additional land rights required. The heights of the existing lattice towers that encompass the project in Florham Park range from approximately 78 feet to 128 feet and the proposed heights of the new structures will range from approximately 110 feet to 150 feet.

In Service

We have completed have completed the replacement of the new structures and have strung the new power line.  The transmission line is in service.

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.
