Flowerfield Reliability Project

Reliability Projects

We're making upgrades to enhance our system's ability to withstand extreme weather and meet energy demands.

Project Specifics

This project was completed in January 2021.

PSEG Long Island will upgrade the existing Flowerfield Substation to address the load growth need in your area. This work will also include the installation of a new substation exit feeder and circuit, underground cable and reconductoring overhead lines. The overhead work will include converting 4,000 feet of single phase, primary branch line to three phase, primary main line. These upgrades will ensure that you and your neighbors receive safe, reliable electric power for years to come.


  • Late September 2019: Inside substation construction, approximately 7 months to complete
  • October 2019: Underground and overhead construction, approximately 3 months to complete

Project Route
Underground work will occur along Mills Pond Road starting at the intersection of North Country Road (25A) and run south to the intersection at Moriches Road. Along the underground portion of the project route, there will be several temporary drill pits for the installation of underground cable. This will allow us to tie the new feeder into existing overhead facilities.

Overhead reconductoring will take place along the following locations:

  • North Country Road (25A): intersections of Edgewood Avenue and Pia Boulevard
  • 2nd Street: Lake Avenue to Moriches Road
  • Moriches Road: intersection of Evon Lane to 7th Avenue

Frequently Asked Questions

Please see the questions below.

  • What are the work hours?
    Crews are scheduled to work Monday through Friday from 7:00 a.m. – 4:00 p.m.
  • Will there be tree trimming?
    Tree trimming is not expected with this project, however if the need arises during construction the work will be minimal and follow our utility best practice model (ANSI A300 standards as well as the Best Management Practices Tree Pruning publication).
  • Will the project include new poles or pole replacements?

New Poles: Three new wood distribution poles will be added at the following locations; one near the intersection of Moriches Road and Mills Pond Road, one near the intersection of Lake Avenue and 2nd Street and one on North Country Road (25A) near the intersection of Mills Pond Road.

Pole Replacements: Along the overhead reconductoring route (Moriches Road and 2nd Street), many wood distribution poles will be replaced with similarly sized wood distribution poles. Also, four wood transmission poles near the substation and Long Island Railroad tracks will be replaced with similarly sized wood transmission poles.

  • Will there be any power outages?
    We do not anticipate any power outages related to this project. However, in the event that a brief outage is required, all affected customers will be notified in advance of any power outage.
