Project Specifics
This project is necessary to address an increase in load as a result of new residential and commercial developments in the Central Islip area. 

This project will install approximately 2.5 miles of 750 CU underground cable, 6 PMH switchgears and 3 switches. The project will include installation of 13,200 feet of cable starting at the Tech Park substation on DPW drive. We will utilize horizontal directional drilling or open trenching. Temporary drill pits will be installed in some areas and trenching will be required to tie-in the new cable to existing equipment. 

Pole Repleacement
A single pole replacement with upgraded pole-top equipment is planned for the southeast corner of Carlton Avenue and Clift Street.

Frequently Asked Questions

Please see below for frequently asked questions. 

• Will the project include tree trimming?
  Trees growing near power lines significantly increase the chance of power outages and pose safety risks. As we expand and improve our electric circuits, we will trim trees, where necessary, following our utility best practice model (ANSI A300 standards as well as the Best Management Practices Tree Pruning publication): 8 feet to each side; 12 feet above; and 10 feet below the line.

  PSEG Long Island does not anticipate any planned power outages related to this project. However, if the need for an outage arises, customers will be notified in advance.
